Emotional and Social Development in Early Childhood

What you’ll learn to do: describe key emotional and social developments of early childhood

The time between a child’s second and sixth birthday is full of new social experiences. At the beginning of this stage, a child selfishly engages in the world—the goal is to please the self. As the child gets older, they realize that relationships built on give-and-take. They start to learn to empathize with others. They learn to make friends. Learning to navigate the social sphere is not easy, but children do it readily.

While the child is learning about their place in various relationships, they are also developing an understanding of emotion. A two-year-old does not have a good grasp on their emotions, but by the time a child is six, they understand their emotions better. They also understand how to control their emotions—even to the point that they may put on a different emotion than they are actually feeling. Further, by the time a child is six years old, they understand that other people have emotions and that all of the emotions involved in a situation (theirs and other people’s) should be taken into consideration. That said, although the six-year-old understands these things, they are not always good at putting the knowledge into action. We’ll examine some of these issues in this section.

Developing a Concept of Self

Self-Concept

Early childhood is a time of forming an initial sense of self. A self-concept or idea of who we are, what we are capable of doing, and how we think and feel is a social process that involves taking into consideration how others view us. It might be said, then, that in order to develop a sense of self, you must have interaction with others.

Exaggerated Sense of Self

One of the ways to gain a clearer sense of self is to exaggerate those qualities that are to be incorporated into the self. Preschoolers often like to exaggerate their own qualities or to seek validation as the biggest or smartest or child who can jump the highest. Much of this may be due to the simple fact that the child does not understand their own limits. Young children may really believe that they can beat their parent to the mailbox, or pick up the refrigerator.

This exaggeration tends to be replaced by a more realistic sense of self in middle childhood as children realize that they do have limitations. Part of this process includes having parents who allow children to explore their capabilities and give the child authentic feedback. Another important part of this process involves the child learning that other people have capabilities, too…and that the child’s capabilities may differ from those of other people. Children learn to compare themselves to others to understand what they are “good at” and what they are not as good at.

Self-Control

One important aspect of self-concept is how we understand our ability to exhibit self-control and delay gratification. Self-control involves both response inhibition and delayed gratification. Response inhibition involves the ability to recognize a potential behavior before it occurs and stop the initiation of behaviors that could result in undesired consequences. Delayed gratification refers to the process of forgoing immediate or short-term rewards to achieve more valuable goals in the longer term. The ability to delay gratification was traditionally assessed in young children with the “Marshmallow Test.” During this experiment, participants were presented with a marshmallow (or another small treat) and were given a choice to eat it or wait for a certain period of time without eating it, so that they could have two marshmallows eventually (Mischel et al., 2011).

While self-control takes many years to develop, we see the beginnings of this skill during early childhood. This ability to delay gratification in young children has been shown to predict many positive outcomes. For instance, preschoolers who were able to delay gratification for a longer period of time had higher levels of resilience, better academic and social competence, and greater planning ability in their adolescence (Mischel et al., 1988). Recent research has linked poor delayed gratification in young children to poor eating self-regulation, specifically regarding eating when not hungry (Hughes et al., 2015) and behavioral problems (Willoughby et al., 2011; Kim et al., 2012).^[1]

Social Development: The Importance of Play

Erikson: Initiative vs. Guilt

Erik Erikson believed that the relationships that people have are what influence personality development. At the beginning of early childhood, the child is still in the autonomy versus shame and doubt stage (stage 2).

By age three, the child begins stage 3: initiative versus guilt. The trust and autonomy of previous stages develop into a desire to take initiative or to think of ideas and initiate action. Children are curious at this age and start to ask questions so that they can learn about the world. Parents should try to answer those questions without making the child feel like a burden or implying that the child’s question is not worth asking.

These children are also beginning to use their imagination (remember what we learned when we discussed Piaget!). Children may want to build a fort with the cushions from the living room couch, open a lemonade stand in the driveway, or make a zoo with their stuffed animals and issue tickets to those who want to come. Another way that children may express autonomy is in wanting to get themselves ready for bed without any assistance. To reinforce taking initiative, caregivers should offer praise for the child’s efforts and avoid being overly critical of messes or mistakes. Soggy washrags and toothpaste left in the sink pale in comparison to the smiling face of a five-year-old emerging from the bathroom with clean teeth and pajamas!

That said, it is important that the parent does their best to kindly guide the child to the right actions. If the child does leave those soggy washrags in the sink, have the child help clean them up. It is possible that the child will not be happy with helping to clean, and the child may even become aggressive or angry, but it is important to remember that the child is still learning how to navigate their world. They are trying to build a sense of autonomy, and they may not react well when they are asked to do something that they had not planned. Parents should be aware of this, and try to be understanding, but also firm. Guilt for a situation where a child did not do their best allows a child to understand their responsibilities and helps the child learn to exercise self-control (remember the marshmallow test). The goal is to find a balance between initiative and guilt, not a free-for-all where the parent allows the child to do anything they want to. The parent must guide the child if they are to have a successful resolution in this stage.

Gender and Early Childhood

Gender Identity, Gender Constancy, and Gender Roles

Another important dimension of the self is the sense of self as male or female. Preschool aged children become increasingly interested in finding out the differences between boys and girls both physically and in terms of what activities are acceptable for each. While two-year-olds can identify some differences and learn whether they are boys or girls, preschoolers become more interested in what it means to be male or female. One’s own sense of their gender is their gender identity. Gender identity emerges between ages two and four and by age four, most children have a stable sense of their gender identity.

Children learn at a young age that there are distinct expectations for boys and girls. Gender roles, or the expectations associated with being male or female, are learned in one’s culture throughout childhood and into adulthood. Cross-cultural studies reveal that children are aware of gender roles by age two or three. At four or five, most children are firmly entrenched in culturally appropriate gender roles (Kane 1996). Children acquire these roles through socialization, a process in which people learn to behave in a particular way as dictated by societal values, beliefs, and attitudes.

Children may also use gender stereotyping readily. Gender stereotyping involves overgeneralizing about the attitudes, traits, or behavior patterns of women or men. A recent research study examined four- and five-year-old children’s predictions concerning the sex of the persons carrying out a variety of common activities and occupations on television. The children’s responses revealed strong gender-stereotyped expectations. They also found that children’s estimates of their own future competence indicated stereotypical beliefs, with the females more likely to reject masculine activities.

Children who are allowed to explore different toys, who are exposed to non-traditional gender roles, and whose parents and caregivers are open to allowing the child to take part in non-traditional play (allowing a boy to nurture a doll, or allowing a girl to play doctor) tend to have broader definitions of what is gender appropriate, and may do less gender stereotyping.

Transgender Children

Many young children do not conform to the gender roles modeled by the culture and even push back against assigned roles. However, a small percentage of children actively reject the toys, clothing, and anatomy of their assigned sex and state they prefer the toys, clothing and anatomy of the opposite sex. Approximately 0.3 percent of the United States population identify as transgender or identifying with the gender opposite their natal sex (Olson & Gülgöz, 2018). Some of these children may experience gender dysphoria, or a marked incongruence between one’s assigned gender and their experienced/expressed gender (American Psychiatric Association, 2022). However, other children do not experience discomfort regarding their gender identity. Transgender adults have stated that they identified with the opposite gender as soon as they began talking (Russo, 2016).

Current research is now looking at those young children who identify as transgender and have socially transitioned. In 2013, a longitudinal study following 300 socially transitioned transgender children between the ages of 3 and 12 began (Olson & Gülgöz, 2018). Socially transitioned transgender children identify with the gender opposite than the one assigned at birth, and they change their appearance and pronouns to reflect their gender identity. Findings from the study indicated that the gender development of these socially transitioned children looked similar to the gender development of cisgender children, or those whose gender and sex assignment at birth matched. These socially transitioned transgender children exhibited similar gender preferences and gender identities as their gender matched peers. Further, these children who were living everyday according to their gender identity and were supported by their families, exhibited positive mental health.

Some individuals who identify as transgender are intersex; that is born with either an absence or some combination of male and female reprodu tive organs, sex hormones, or sex chromosomes (Jarne & Auld, 2006). In humans, intersex individuals make up more than 150 million people, or about two percent of the world’s population (Blackless et al., 2000). There are dozens of intersex conditions, and intersex individuals demonstrate the diverse variations of biological sex. Greater attention to the rights of chi dren born intersex is occurring in the medical field, and intersex children and their parents should work closely with specialists to ensure these children develop positive gender identities.

Learning Through Reinforcement and Modeling

Learning theorists suggest that gender role socialization is a result of the ways in which parents, teachers, friends, schools, religious institutions, media, and others send messages about what is acceptable or desirable behavior for males or females. This socialization begins early—in fact, it may even begin the moment a parent learns that a child is on the way. Knowing the sex of the child can conjure up images of the child’s behavior, appearance, and potential on the part of a parent. And this stereotyping continues to guide perception through life. Consider parents of newborns. Shown a 7-pound, 20-inch baby, wrapped in blue (a color designating males) describe the child as tough, strong, and angry when crying. Shown the same infant in pink (a color used in the United States for baby girls), these parents are likely to describe the baby as pretty, delicate, and frustrated when crying (Maccoby & Jacklin, 1987). Female infants are held more, talked to more frequently and given direct eye contact, while male infants’ play is often mediated through a toy or activity.

One way children learn gender roles is through play. Parents typically supply boys with trucks, toy guns, and superhero paraphernalia, which are active toys that promote motor skills, aggression, and solitary play. Daughters are often given dolls and dress-up apparel that foster nurturing, social proximity, and role play. Studies have shown that children will most likely choose to play with “gender appropriate” toys (or same-gender toys) even when cross-gender toys are available because parents give children positive feedback (in the form of praise, involvement, and physical closeness) for gender normative behavior (Caldera, Huston, and O’Brien 1998).

Sons are given tasks that take them outside the house and that have to be performed only on occasion, while girls are more likely to be given chores inside the home, such as cleaning or cooking, that are performed daily. Sons are encouraged to think for themselves when they encounter problems, and daughters are more likely to be given assistance even when they are working on an answer. This impatience is reflected in teachers waiting less time when asking a female student for an answer than when asking for a reply from a male student (Sadker and Sadker, 1994). Girls are given the message from teachers that they must try harder and endure in order to succeed while boys successes are attributed to their intelligence. Of course, the stereotypes of advisors can also influence which kinds of courses or vocational choices girls and boys are encouraged to make.

Friends discuss what is acceptable for boys and girls, and popularity may be based on modeling what is considered ideal behavior or appearance for the sexes. Girls tend to tell one another secrets to validate others as best friends, while boys compete for position by emphasizing their knowledge, strength or accomplishments. This focus on accomplishments can even give rise to exaggerating accomplishments in boys, but girls are discouraged from showing off and may learn to minimize their accomplishments as a result.

Gender messages abound in our environment. But does this mean that each of us receives and interprets these messages in the same way? Probably not. In addition to being recipients of these cultural expectations, we are individuals who also modify these roles (Kimmel, 2008).

One interesting recent finding is that girls may have an easier time breaking gender norms than boys.^[4] Girls who play with masculine toys often do not face the same ridicule from adults or peers that boys face when they want to play with feminine toys. Girls also face less ridicule when playing a masculine role (like doctor) as opposed to a boy who wants to take a feminine role (like caregiver).

The Impact of Gender Discrimination

How much does gender matter? In the United States, gender differences are found in school experiences. Even into college and professional school, girls are less vocal in class and much more at risk for sexual harassment from teachers, coaches, classmates, and professors. These gender differences are also found in social interactions and in media messages. The stereotypes that boys should be strong, forceful, active, dominant, and rational, and that girls should be pretty, subordinate, unintelligent, emotional, and talkative are portrayed in children’s toys, books, commercials, video games, movies, television shows, and music. In adulthood, these differences are reflected in income gaps between men and women (women working full-time earn about 74 percent the income of men), in higher rates of women suffering rape and domestic violence, higher rates of eating disorders for females, and in higher rates of violent death for men in young adulthood.

Gender differences in India can be a matter of life and death as preferences for male children have been historically strong and are still held, especially in rural areas (WHO, 2010). Male children are given preference for receiving food, breast milk, medical care, and other resources. In some countries, it is no longer legal to give parents information on the sex of their developing child for fear that they will abort a female fetus. Clearly, gender socialization and discrimination still impact development in a variety of ways across the globe. Gender discrimination generally persists throughout the lifespan in the form of obstacles to education, or lack of access to political, financial, and social power.

Family Life and Parenting Styles

Parenting Styles

Relationships between parents and children continue to play a significant role in children’s development during early childhood. We will explore two models of parenting styles. Keep in mind that most parents do not follow any model completely. Real people tend to fall somewhere in between these styles. And sometimes parenting styles change from one child to the next or in times when the parent has more or less time and energy for parenting. Parenting styles can also be affected by concerns the parent has in other areas of their life. For example, parenting styles tend to become more authoritarian when parents are tired and perhaps more authoritative when they are more energetic. Sometimes parents seem to change their parenting approach when others are around, maybe because they become more self-conscious as parents or are concerned with giving others the impression that they are a “tough” parent or an “easy-going” parent. And of course, parenting styles may reflect the type of parenting someone saw modeled while growing up.

Baumrind’s Parenting Styles

Baumrind (1971) offers a model of parenting that includes three styles. The first, authoritarian, is the traditional model of parenting in which parents make the rules and children are expected to be obedient. Baumrind suggests that authoritarian parents tend to place maturity demands on their children that are unreasonably high and tend to be aloof and distant. Consequently, children reared in this way may fear rather than respect their parents and, because their parents do not allow discussion, may take out their frustrations on safer targets – perhaps as bullies toward peers.

Permissive parenting involves being a friend to a child rather than an authority figure. Children are allowed to make their own rules and determine their own activities. Parents are warm and communicative but provide little structure for their children. Children may fail to learn self-discipline and may feel somewhat insecure because they do not know the limits.

Authoritative parenting involves being appropriately strict, reasonable, and affectionate. Parents allow negotiation where appropriate and discipline matches the severity of the offense. A popular parenting program that is offered in many school districts is called “Love and Logic” and reflects the authoritative or democratic style of parenting just described.

Today we recognize a fourth style within the Baumrind framework: uninvolved parenting. These parents are disengaged from their children. They do not make demands on their children and are non-responsive. These children can suffer in school and in their relationships with their peers (Gecas & Self, 1991).

The most important thing to remember about parenting is that you can be a better, more objective parent when you are directing your actions toward the child’s needs while considering what they can reasonably be expected to do at their stage of development. Parenting is more difficult when you are tired and have psychological needs that interfere with the relationship. Some of the best advice for parents is to try not to take the child’s actions personally, and be as objective as possible.

Class and Culture

The impact of class and culture cannot be ignored when examining parenting styles. The two models of parenting described above assume that authoritative and athletic coaching styles are best because they are designed to help the parent raise a child who is independent, self-reliant, and responsible. These are qualities favored in “individualistic” cultures such as the United States, particularly by the middle class.

Authoritarian parenting has been used historically and reflects the cultural need for children to do as they are told. African-American, Hispanic, and Asian parents tend to be more authoritarian than non-Hispanic whites. In collectivistic cultures such as China or Korea, being obedient and compliant are favored behaviors. In societies where family members’ cooperation is necessary for survival, as in the case of raising crops, rearing children who are independent and who strive to be on their own makes no sense. But in an economy based on being mobile in order to find jobs and where one’s earnings are based on education, raising a child to be independent is very important.

Working class parents are more likely than middle-class parents to focus on obedience and honesty when raising their children. In a classic study on social class and parenting styles called Class and Conformity, Kohn (1977) explained that parents tend to emphasize qualities that are needed for their own survival when parenting their children. Working class parents are rewarded for being obedient, reliable, and honest in their jobs. They are not paid to be independent or to question the management; rather, they move up and are considered good employees if they show up on time, do their work as they are told, and can be counted on by their employers. Consequently, these parents reward honesty and obedience in their children. Middle-class parents who work as professionals are rewarded for taking initiative, being self-directed, and assertive in their jobs. They are required to get the job done without being told exactly what to do. They are asked to be innovative and to work independently. These parents encourage their children to have those qualities as well by rewarding independence and self-reliance. Parenting styles can reflect many elements of culture.

Child Care Concerns

About 75.7 percent of mothers of school-aged and 65.1 percent of mothers of preschool aged children in the United States work outside the home^[5]. Since more women have been entering the workplace, there has been a concern that families do not spend as much time with their children. This, however, may not be true. Between 1981 and 1997, the amount of time that parents spent with children increased overall (Sandberg and Hofferth, 2001). Modern numbers for this vary widely, as many parents who work outside of the home also devote significant amounts of time to childcare, to 14 hours a week, compared with 10 in 1965.^[6] The amount of this time that is undistracted and involved may be close to 34 minutes a day.^[7]

Seventy-five percent of children under age 5 are in scheduled child care programs. Others are cared for by family members, friends, or are in Head Start Programs. Older children are often in after school programs, before school programs, or stay at home alone after school once they are older. Quality childcare programs can enhance a child’s social skills and can provide rich learning experiences. But long hours in poor quality care can have negative consequences for young children in particular. What determines the quality of child care? One very important consideration is the teacher/child ratio. States specify the maximum number of children that can be supervised by one teacher. In general, the younger the children, the more teachers required for a given number of children. The lower the teacher to child ratio, the more time the teacher has for involvement with the children and the less stressed the teacher may be so that the interactions can be more relaxed, stimulating and positive. The more children there are in a program, the less desirable the program as well. This is because the center may be more rigid in rules and structure to accommodate the large number of children in the facility.

The physical environment should be colorful, stimulating, clean, and safe. The philosophy of the organization and the curriculum available should be child-centered, positive, and stimulating. Providers should be trained in early childhood education as well. A majority of states do not require training for their child care providers. And while formal education is not required for a person to provide a warm, loving relationship to a child, knowledge of a child’s development is useful for addressing their social, emotional, and cognitive needs in an effective way. By working toward improving the quality of childcare and increasing family-friendly workplace policies, such as more flexible scheduling and perhaps childcare facilities at places of employment, we can accommodate families with smaller children and relieve parents of the stress sometimes associated with managing work and family life.

Learning and Behavior Modification

Parenting and Behaviorism

Parenting generally involves many opportunities to apply principles of behaviorism, especially operant conditioning. In discussing operant conditioning, we use several everyday words—positive, negative, reinforcement, and punishment—in a specialized manner. In operant conditioning, positive and negative do not mean good and bad. Instead, positive means you are adding something, and negative means you are taking something away. Reinforcement means you are increasing a behavior, and punishment means you are decreasing a behavior. Reinforcement can be positive or negative, and punishment can also be positive or negative. All reinforcers (positive or negative) increase the likelihood of a behavioral response. All punishers (positive or negative) decrease the likelihood of a behavioral response. Now let’s combine these four terms: positive reinforcement, negative reinforcement, positive punishment, and negative punishment. (See table below.)

The most effective way to teach a person or animal a new behavior is with positive reinforcement. In positive reinforcement, a stimulus is added to the situation to increase a behavior. Parents and teachers use positive reinforcement all the time, from offering dessert after dinner, praising children for cleaning their room or completing some work, offering a toy at the end of a successful piano recital, or earning more time for recess. The goal of providing these forms of positive reinforcement is to increase the likelihood of the same behavior occurring in the future.

Positive reinforcement is an extremely effective learning tool, as evidenced by nearly 80 years worth of research. That said, there are many ways to introduce positive reinforcement into a situation. Many people believe that reinforcers must be tangible, but research shows that verbal praise and hugs are very effective reinforcers for people of all ages. Further, research suggests that constantly providing tangible reinforcers may actually be counterproductive in certain situations. For example, paying children for their grades may undermine their intrinsic motivation to go to school and do well. While children who are paid for their grades may maintain good grades, it is to receive the reinforcing pay, not because they have an intrinsic desire to do well. The impact is especially detrimental to students who initially have a high level of intrinsic motivation to do well in school. Therefore, we must provide appropriate reinforcement, and be careful to ensure that the reinforcement does not undermine intrinsic motivation.

In negative reinforcement, an aversive stimulus is removed to increase a behavior. For example, car manufacturers use the principles of negative reinforcement in their seatbelt systems, which go “beep, beep, beep” until you fasten your seatbelt. The annoying sound stops when you exhibit the desired behavior, increasing the likelihood that you will buckle up in the future. Negative reinforcement is also used frequently in horse training. Riders apply pressure—by pulling the reins or squeezing their legs—and then remove the pressure when the horse performs the desired behavior, such as turning or speeding up. The pressure is the negative stimulus that the horse wants to remove.

Sometimes, adding something to the situation is reinforcing as in the cases we described above with cookies, praise, and money. Positive reinforcement involves adding something to the situation in order to encourage a behavior. Other times, taking something away from a situation can be reinforcing. For example, the loud, annoying buzzer on your alarm clock encourages you to get up so that you can turn it off and get rid of the noise. Children whine in order to get their parents to do something and often, parents give in just to stop the whining. In these instances, children have used negative reinforcement to get what they want.

Operant conditioning tends to work best if you focus on trying to encourage a behavior or move a person into the direction you want them to go rather than telling them what not to do. Reinforcers are used to encourage behavior; punishers are used to stop the behavior. A punisher is anything that follows an act and decreases the chance it will reoccur. As with reinforcement, there are also two types of punishment: positive punishment and negative punishment.

Positive punishment involves adding something in order to decrease the likelihood that a behavior will occur again in the future. Spanking is an example of positive punishment. Receiving a speeding ticket is also an example of positive punishment. Both of these punishers, the spanking and the speeding ticket, are intended to decrease the reoccurrence of the related behavior.

Negative punishment involves removing something that is desired in order to decrease the likelihood that a behavior will occur again in the future. Putting a child in time out can serve as a negative punishment if the child enjoys social interaction. Taking away a child’s technology privileges can also be a negative punishment. Taking away something that is desired encourages the child to refrain from engaging in that behavior again in order to not lose the desired object or activity.

Often, punished behavior doesn’t really go away. It is just suppressed and may reoccur whenever the threat of punishment is removed. For example, a child may not cuss around you because you’ve washed his mouth out with soap, but he may cuss around his friends. A motorist may only slow down when the trooper is on the side of the freeway. Another problem with punishment is that when a person focuses on punishment, they may find it hard to see what the other does right or well. Punishment is stigmatizing; when punished, some people start to see themselves as bad and give up trying to change.

Reinforcement can occur in a predictable way, such as after every desired action is performed (called continuous reinforcement), or intermittently, after the behavior is performed a number of times or the first time it is performed after a certain amount of time (called partial reinforcement whether based on the number of times or the passage of time). The schedule of reinforcement has an impact on how long a behavior continues after reinforcement is discontinued. So a parent who has rewarded a child’s actions each time may find that the child gives up very quickly if a reward is not immediately forthcoming. Children will learn quickest under a continuous schedule of reinforcement. Then the parent should switch to a schedule of partial reinforcement to maintain the behavior.

Everyday Connection: Behavior Modification in Children

Parents and teachers often use behavior modification to change a child’s behavior. Behavior modification uses the principles of operant conditioning to accomplish behavior change so that undesirable behaviors are switched for more socially acceptable ones. Some teachers and parents create a sticker chart, in which several behaviors are listed. Sticker charts are a form of token economies. Each time children perform the behavior, they get a sticker, and after a certain number of stickers, they get a prize or reinforcer. The goal is to increase acceptable behaviors and decrease misbehavior. Remember, it is best to reinforce desired behaviors, rather than to use punishment. In the classroom, the teacher can reinforce a wide range of behaviors, from students raising their hands, to walking quietly in the hall, to turning in their homework. At home, parents might create a behavior chart that rewards children for things such as putting away toys, brushing their teeth, and helping with dinner. In order for behavior modification to be effective, the reinforcement needs to be connected with the behavior; the reinforcement must matter to the child and be provided consistently.

Time-out is another popular technique used in behavior modification with children. It operates on the principle of negative punishment. When a child demonstrates an undesirable behavior, she is removed from the desirable activity at hand. For example, say that Sophia and her brother Mario are playing with building blocks. Sophia throws some blocks at her brother, so you give her a warning that she will go to time-out if she does it again. A few minutes later, she throws more blocks at Mario. You remove Sophia from the room for a few minutes. When she comes back, she doesn’t throw blocks.

There are several important points that you should know if you plan to implement time-out as a behavior modification technique. First, make sure the child is being removed from a desirable activity and placed in a less desirable location. If the activity is something undesirable for the child, this technique will backfire because it is more enjoyable for the child to be removed from the activity. Second, the length of the time-out is important. The general rule of thumb is one minute for each year of the child’s age. Sophia is five; therefore, she sits in a time-out for five minutes. Setting a timer helps children know how long they have to sit in time-out. Finally, as a caregiver, keep several guidelines in mind over the course of a time-out: remain calm when directing your child to time-out; ignore your child during a time-out (because caregiver attention may reinforce misbehavior), and give the child a hug or a kind word when time-out is over.

Childhood Stress and Development

Stress in Early Childhood

What is the impact of stress on child development? The answer to that question is complex and depends on several factors including the number of stressors, the duration of stress, and the child’s ability to cope with stress.

Children experience different types of stressors that could be manifest in various ways. Normal, everyday stress can provide an opportunity for young children to build coping skills and poses little risk to development. Even long-lasting stressful events, such as changing schools or losing a loved one, can be managed fairly well.

Some experts have theorized that there is a point where prolonged or excessive stress becomes harmful and can lead to serious health effects. When stress builds up in early childhood, neurobiological factors are affected; in turn, levels of the stress hormone cortisol exceed normal ranges. Due in part to the biological consequences of excessive cortisol, children can develop physical, emotional, and social symptoms. Physical conditions include cardiovascular problems, skin conditions, susceptibility to viruses, headaches, or stomach aches in young children. Emotionally, children may become anxious or depressed, violent, or feel overwhelmed. Socially, they may become withdrawn and act out towards others, or develop new behavioral ticks such as biting nails or picking at skin.

Consequences of Toxic Stress

Children who experience toxic stress or who live in extremely stressful situations of abuse over long periods of time can suffer long-lasting effects. The structures in the midbrain or limbic system, such as the hippocampus and amygdala, can be vulnerable to prolonged stress (Middlebrooks and Audage, 2008). High levels of the stress hormone cortisol can reduce the size of the hippocampus and effect a child’s memory abilities. Stress hormones can also reduce immunity to disease. If the brain is exposed to long periods of severe stress, it can develop a low threshold, making a child hypersensitive to stress in the future.

With chronic toxic stress, children undergo long term hyper-arousal of brain stem activity. This includes an increase in heart rate, blood pressure, and arousal states. These children may experience a change in brain chemistry, which leads to hyperactivity and anxiety. Therefore, it is evident that chronic stress in a young child’s life can create significant physical, emotional, psychological, social and behavioral changes; however, the effects of stress can be minimized if the child has the support of caring adults.

Trauma in Childhood

All types of abuse, neglect, and other potentially traumatic experiences that occur before the age of 18 are referred to as adverse childhood experiences (ACEs). Children may go through a range of experiences that classify as psychological trauma, these might include neglect, abandonment, sexual abuse, physical abuse, parent or sibling treated violently, separation or incarceration of parents, or having a parent with a mental illness. These events have profound psychological, physiological, and sociological impacts and can have negative, lasting effects on health and well-being.

Kaiser Permanente and the Centers for Disease Control and Prevention’s 1998 study on adverse childhood experiences determined that traumatic experiences during childhood are a root cause of many social, emotional, and cognitive impairments that lead to increased risk of unhealthy self-destructive behaviors, risk of violence or re-victimization, chronic health conditions, low life potential, and premature mortality. As the number of adverse experiences increases, the risk of problems from childhood through adulthood also rises. Nearly 30 years of study following the initial study has confirmed this. Many states, health providers, and other groups now routinely screen parents and children for ACEs.

Food Insecurity

In 2017 11.8% of households experienced low food security, or food insecurity, at some point during that year.^[8] Food insecurity happens when a family has limited or uncertain availability of safe, nutritious food. The most recent statistics suggest that households with children are more at risk for food insecurity, with nearly 18% of children under the age of 18 living in households that have experienced food insecurity within the year.^[9] Lack of proper nutrition is a stress on the body in general. Children who are undernourished may have physical developmental delays. Further, food insecurity has been correlated with poor school performance in both reading and math.^[10]
