Social-Emotional Development

S ocial-emotional development includes the child’s experience, expression, and management of

emotions and the ability to establish positive and rewarding relationships with others (Cohen and others 2005). It encompasses both intra- and inter­ personal processes.

The core features of emotional devel­ opment include the ability to identify and understand one’s own feelings, to accurately read and comprehend emotional states in others, to manage strong emotions and their expression in a constructive manner, to regu­ late one’s own behavior, to develop empathy for others, and to establish and maintain relationships. (National Scientific Council on the Developing Child 2004, 2)

Infants experience, express, and per­ ceive emotions before they fully under­ stand them. In learning to recognize, label, manage, and communicate their emotions and to perceive and attempt to understand the emotions of others, children build skills that connect them with family, peers, teachers, and the community. These growing capacities help young children to become compe­ tent in negotiating increasingly com­

plex social interactions, to participate effectively in relationships and group activities, and to reap the benefits of social support crucial to healthy human development and functioning.

Healthy social-emotional develop­ ment for infants and toddlers unfolds in an interpersonal context, namely that of positive ongoing relationships with familiar, nurturing adults. Young children are particularly attuned to social and emotional stimulation. Even newborns appear to attend more to stimuli that resemble faces (John­ son and others 1991). They also pre­ fer their mothers’ voices to the voices of other women (DeCasper and Fifer 1980). Through nurturance, adults support the infants’ earliest experi­ ences of emotion regulation (Bronson 2000a; Thompson and Goodvin 2005).

Responsive caregiving supports infants in beginning to regulate their emotions and to develop a sense of predictability, safety, and responsive­ ness in their social environments. Early relationships are so important to developing infants that research experts have broadly concluded that, in the early years, “nurturing, stable and consistent relationships are the

key to healthy growth, development and learning” (National Research Council and Institute of Medicine 2000, 412). In other words, high- quality relationships increase the likelihood of positive outcomes for young children (Shonkoff 2004). Experiences with family members and teachers provide an opportunity for young children to learn about social relationships and emotions through exploration and predictable interac­ tions. Professionals working in child care settings can support the social- emotional development of infants and toddlers in various ways, including interacting directly with young chil­ dren, communicating with families, arranging the physical space in the care environment, and planning and implementing curriculum.

Brain research indicates that emo­ tion and cognition are profoundly interrelated processes. Specifically, “recent cognitive neuroscience findings suggest that the neural mechanisms underlying emotion regulation may be the same as those underlying cogni­ tive processes” (Bell and Wolfe 2004, 366). Emotion and cognition work together, jointly informing the child’s impressions of situations and influ­ encing behavior. Most learning in the early years occurs in the context of emotional supports (National Research Council and Institute of Medicine 2000). “The rich interpenetrations of emotions and cognitions establish the major psychic scripts for each child’s life” (Panksepp 2001). Together, emo­ tion and cognition contribute to atten­ tional processes, decision making, and learning (Cacioppo and Berntson 1999). Furthermore, cognitive pro­ cesses, such as decision making, are affected by emotion (Barrett and oth­

ers 2007). Brain structures involved in the neural circuitry of cognition influ­ ence emotion and vice versa (Barrett and others 2007). Emotions and social behaviors affect the young child’s abil­ ity to persist in goal-oriented activity, to seek help when it is needed, and to participate in and benefit from rela­ tionships.

Young children who exhibit healthy social, emotional, and behavioral adjustment are more likely to have good academic performance in elemen­ tary school (Cohen and others 2005; Zero to Three 2004). The sharp dis­ tinction between cognition and emo­ tion that has historically been made may be more of an artifact of scholar­ ship than it is representative of the way these processes occur in the brain (Barrett and others 2007). This recent research strengthens the view that early childhood programs support later positive learning outcomes in all domains by maintaining a focus on the promotion of healthy social emo­ tional development (National Scientific Council on the Developing Child 2004; Raver 2002; Shonkoff 2004).

Interactions with Adults Interactions with adults are a fre­

quent and regular part of infants’ daily lives. Infants as young as three months of age have been shown to be able to discriminate between the faces of unfamiliar adults (Barrera and Maurer 1981). The foundations that describe Interactions with Adults and Relationships with Adults are inter­ related. They jointly give a picture of healthy social-emotional development that is based in a supportive social environment established by adults. Children develop the ability to both

respond to adults and engage with them first through predictable interac­ tions in close relationships with par­ ents or other caring adults at home and outside the home. Children use and build upon the skills learned through close relationships to inter­ act with less familiar adults in their lives. In interacting with adults, chil­ dren engage in a wide variety of social exchanges such as establishing con­ tact with a relative or engaging in sto­ rytelling with an infant care teacher.

Quality in early childhood programs is, in large part, a function of the interactions that take place between the adults and children in those programs. These interactions form the basis for the relationships that are established between teachers and children in the classroom or home and are related to children’s develop­ mental status. How teachers interact with children is at the very heart of early childhood education (Kontos and Wilcox-Herzog 1997, 11).

Relationships with Adults Close relationships with adults

who provide consistent nurturance strengthen children’s capacity to learn and develop. Moreover, relation­ ships with parents, other family mem­ bers, caregivers, and teachers provide the key context for infants’ social- emotional development. These special relationships influence the infant’s emerging sense of self and under­ standing of others. Infants use rela­ tionships with adults in many ways: for reassurance that they are safe, for assistance in alleviating distress, for help with emotion regulation, and for social approval or encouragement. Establishing close relationships with

adults is related to children’s emo­ tional security, sense of self, and evolv­ ing understanding of the world around them. Concepts from the literature on attachment may be applied to early childhood settings, in considering the infant care teacher’s role in separa­ tions and reunions during the day in care, facilitating the child’s explora­ tion, providing comfort, meeting physi­ cal needs, modeling positive relation­ ships, and providing support during stressful times (Raikes 1996).

Interactions with Peers In early infancy children interact

with each other using simple behav­ iors such as looking at or touching another child. Infants’ social interac­ tions with peers increase in complexity from engaging in repetitive or routine back-and-forth interactions with peers (for example, rolling a ball back and forth) to engaging in cooperative activi­ ties such as building a tower of blocks together or acting out different roles during pretend play. Through inter­ actions with peers, infants explore their interest in others and learn about social behavior/social interac­ tion. Interactions with peers provide the context for social learning and problem solving, including the experi­ ence of social exchanges, cooperation, turn-taking, and the demonstration of the beginning of empathy. Social interactions with peers also allow older infants to experiment with different roles in small groups and in different situations such as relating to familiar versus unfamiliar children. As noted, the foundations called Interactions with Adults, Relationships with Adults, Interactions with Peers, and Rela­ tionships with Peers are interrelated.

Interactions are stepping-stones to relationships. Burk (1996, 285) writes:

We, as teachers, need to facilitate the development of a psychologically safe environment that promotes posi­ tive social interaction. As children interact openly with their peers, they learn more about each other as indi­ viduals, and they begin building a history of interactions.

Relationships with Peers Infants develop close relationships

with children they know over a period of time, such as other children in the family child care setting or neighbor­ hood. Relationships with peers provide young children with the opportunity to develop strong social connections. Infants often show a preference for playing and being with friends, as compared with peers with whom they do not have a relationship. Howes’ (1983) research suggests that there are distinctive patterns of friendship for the infant, toddler, and preschooler age groups. The three groups vary in the number of friendships, the stability of friendships, and the nature of inter­ action between friends (for example, the extent to which they involve object exchange or verbal communication).

Identity of Self in Relation to Others

Infants’ social-emotional develop­ ment includes an emerging awareness of self and others. Infants demon­ strate this foundation in a number of ways. For example, they can respond to their names, point to their body parts when asked, or name members of their families. Through an emerg­ ing understanding of other people in their social environment, children gain

an understanding of their roles within their families and communities. They also become aware of their own prefer­ ences and characteristics and those of others.

Recognition of Ability Infants’ developing sense of self-

efficacy includes an emerging under­ standing that they can make things happen and that they have particular abilities. Self-efficacy is related to a sense of competency, which has been identified as a basic human need (Connell 1990). The development of children’s sense of self-efficacy may be seen in play or exploratory behaviors when they act on an object to pro­ duce a result. For example, they pat a musical toy to make sounds come out. Older infants may demonstrate recog­ nition of ability through “I” statements, such as “I did it” or “I’m good at draw­ ing.”

Expression of Emotion Even early in infancy, children

express their emotions through facial expressions, vocalizations, and body language. The later ability to use words to express emotions gives young children a valuable tool in gaining the assistance or social support of oth­ ers (Saarni and others 2006). Tem­ perament may play a role in children’s expression of emotion. Tronick (1989, 112) described how expression of emotion is related to emotion regula­ tion and communication between the mother and infant: “the emotional expressions of the infant and the care­ taker function to allow them to mutu­ ally regulate their interactions . . . the infant and the adult are participants in an affective communication system.”

��

Both the understanding and expres­ sion of emotion are influenced by cul­ ture. Cultural factors affect children’s growing understanding of the meaning of emotions, the developing knowl­ edge of which situations lead to which emotional outcomes, and their learn­ ing about which emotions are appro­ priate to display in which situations (Thompson and Goodvin 2005). Some cultural groups appear to express cer­ tain emotions more often than other cultural groups (Tsai, Levenson, and McCoy 2006). In addition, cultural groups vary by which particular emo­ tions or emotional states they value (Tsai, Knutson, and Fung 2006). One study suggests that cultural differ­ ences in exposure to particular emo­ tions through storybooks may contrib­ ute to young children’s preferences for particular emotional states (for exam­ ple, excited or calm) (Tsai and others 2007).

Young children’s expression of posi­ tive and negative emotions may play a significant role in their development of social relationships. Positive emotions appeal to social partners and seem to enable relationships to form, while problematic management or expression of negative emotions leads to difficulty in social relationships (Denham and Weissberg 2004). The use of emotion- related words appears to be associ­ ated with how likable preschoolers are considered by their peers. Children who use emotion-related words were found to be better-liked by their class­ mates (Fabes and others 2001). Infants respond more positively to adult vocal­ izations that have a positive affective tone (Fernald 1993). Social smiling is a developmental process in which neu­ rophysiology and cognitive, social, and

emotional factors play a part, seen as a “reflection and constituent of an inter­ active relationship” (Messinger and Fogel 2007, 329). It appears likely that the experience of positive emotions is a particularly important contributor to emotional well-being and psychologi­ cal health (Fredrickson 2000, 2003; Panksepp 2001).

Empathy During the first three years of life,

children begin to develop the capacity to experience the emotional or psycho­ logical state of another person (Zahn- Waxler and Radke-Yarrow 1990). The following definitions of empathy are found in the research literature: “knowing what another person is feel­ ing,” “feeling what another person is feeling,” and “responding compassion­ ately to another’s distress” (Levenson and Ruef 1992, 234). The concept of empathy reflects the social nature of emotion, as it links the feelings of two or more people (Levenson and Ruef 1992). Since human life is relation­ ship-based, one vitally important func­ tion of empathy over the life span is to strengthen social bonds (Anderson and Keltner 2002). Research has shown a correlation between empathy and pro- social behavior (Eisenberg 2000). In particular, prosocial behaviors, such as helping, sharing, and comforting or showing concern for others, illustrate the development of empathy (Zahn- Waxler and others 1992) and how the experience of empathy is thought to be related to the development of moral behavior (Eisenberg 2000). Adults model prosocial/empathic behav­ iors for infants in various ways. For example, those behaviors are modeled through caring interactions with oth-

ers or through providing nurturance to the infant. Quann and Wien (2006, 28) suggest that one way to support the development of empathy in young children is to create a culture of caring in the early childhood environment: “Helping children understand the feel­ ings of others is an integral aspect of the curriculum of living together. The relationships among teachers, between children and teachers, and among children are fostered with warm and caring interactions.”

Emotion Regulation The developing ability to regulate

emotions has received increasing attention in the research literature (Eisenberg, Champion, and Ma 2004). Researchers have generated various definitions of emotion regulation, and debate continues as to the most useful and appropriate way to define this con­ cept (Eisenberg and Spinrad 2004). As a construct, emotion regulation reflects the interrelationship of emotions, cognitions, and behaviors (Bell and Wolfe 2004). Young children’s increas­ ing understanding and skill in the use of language is of vital importance in their emotional development, opening new avenues for communicating about and regulating emotions (Campos, Frankel, and Camras 2004) and help­ ing children to negotiate acceptable outcomes to emotionally charged situa­ tions in more effective ways. Emotion regulation is influenced by culture and the historical era in which a person lives: cultural variability in regula­ tion processes is significant (Mesquita and Frijda 1992). “Cultures vary in terms of what one is expected to feel, and when, where, and with whom one may express different feelings” (Cheah

and Rubin 2003, 3). Adults can pro­ vide positive role models of emotion regulation through their behavior and through the verbal and emotional support they offer children in manag­ ing their emotions. Responsiveness to infants’ signals contributes to the development of emotion regulation. Adults support infants’ development of emotion regulation by minimizing exposure to excessive stress, chaotic environments, or over- or understimu­ lation.

Emotion regulation skills are impor­ tant in part because they play a role in how well children are liked by peers and teachers and how socially compe­ tent they are perceived to be (National Scientific Council on the Develop­ ing Child 2004). Children’s ability to regulate their emotions appropriately can contribute to perceptions of their overall social skills as well as to the extent to which they are liked by peers (Eisenberg and others 1993). Poor emotion regulation can impair chil­ dren’s thinking, thereby compromising their judgment and decision making (National Scientific Council on the Developing Child 2004). At kindergar­ ten entry, children demonstrate broad variability in their ability to self-regu­ late (National Research Council and Institute of Medicine 2000).

Impulse Control Children’s developing capacity to

control impulses helps them adapt to social situations and follow rules. As infants grow, they become increasingly able to exercise voluntary control over behavior such as waiting for needs to be met, inhibiting potentially hurtful behavior, and acting according to social expectations, including safety

��

rules. Group care settings provide many opportunities for children to practice their impulse-control skills. Peer interactions often offer natural opportunities for young children to practice impulse control, as they make progress in learning about cooperative play and sharing. Young children’s understanding or lack of understand­ ing of requests made of them may be one factor contributing to their responses (Kaler and Kopp 1990).

Social Understanding During the infant/toddler years,

children begin to develop an under­ standing of the responses, commu­ nication, emotional expression, and actions of other people. This develop­ ment includes infants’ understanding of what to expect from others, how to

engage in back-and-forth social inter­ actions, and which social scripts are to be used for which social situations. “At each age, social cognitive under­ standing contributes to social compe­ tence, interpersonal sensitivity, and an awareness of how the self relates to other individuals and groups in a com­ plex social world” (Thompson 2006, 26). Social understanding is particu­ larly important because of the social nature of humans and human life, even in early infancy (Wellman and Lagattuta 2000). Recent research sug­ gests that infants’ and toddlers’ social understanding is related to how often they experience adult communica­ tion about the thoughts and emotions of others (Taumoepeau and Ruffman 2008).

At around eight months of age, children purposefully engage in reciprocal interac­ tions and try to influence the behavior of others. Children may be both interested in and cautious of unfamiliar adults. (7 mos.; Lamb, Bornstein, and Teti 2002, 340) (8 mos.; Meisels and others 2003, 16)

For example, the child may:

• Attend to an unfamiliar adult with interest but show wariness or become anxious when that adult comes too close. (5–8 mos.; Parks 2004; Johnstone and Scherer 2000, 222)

• Take the infant care teacher’s hands and rock forward and backwards as a way of asking her to sing a favorite song. (8 mos.; Gustafson, Green, and West 1979; Kaye and Fogel 1980)

• Engage in games such as pat­ a-cake and peek-a-boo. (7–9 mos.; Coplan 1993, 3)

• Make eye contact with a family member.

• Vocalize to get an infant care teacher’s attention.

At around 18 months of age, children may participate in rou­ tines and games that involve complex back-and-forth inter­ action and may follow the gaze of the infant care teacher to an object or person. Children may also check with a familiar infant care teacher when uncertain about something or someone. (18 mos.; Meisels and others 2003, 33)

For example, the child may:

• Move close to the infant care teacher and hold his hand when a visitor enters the classroom but watch the visitor with inter­ est. (18 mos.; Meisels and oth­ ers 2003)

• Bring a familiar object to an adult when asked. (15–18 mos.; Parks 2004)

• Allow an unfamiliar adult to get close only after the adult uses an object to bridge the interac­ tion, such as showing interest in a toy that is also interesting to the child. (18 mos.; Meisels and others 2003)

• Watch, and then help the infant care teacher as she prepares snack.

• Seek reassurance from the infant care teacher when unsure if something is safe. (10–12 mos.; Fogel 2001, 305; Dickstein and Parke 1988; Hirshberg and Svejda 1990)

At around 36 months of age, children interact with adults to solve problems or commu­ nicate about experiences or ideas. (California Department of Education 2005, 6; Marvin and Britner 1999, 60).

For example, the child may:

• Participate in storytelling with the infant care teacher. (30–36 mos.; Parks 2004)

• Tell a teacher from the class­ room next door about an upcoming birthday party. (36 mos.; Parks 2004)

• Help the infant care teacher bring in the wheeled toys from the play yard at the end of the day.

• Ask a classroom visitor her name.

8 months

At around eight months of age, children seek a special relationship with one (or a few) familiar adult(s) by initiating interactions and seek­ ing proximity, especially when distressed. (6–9 mos.; Marvin and Britner 1999, 52)

For example, the child may:

• Seek comfort from the infant care teacher by crying and looking for him. (7 mos.; Lamb, Bornstein, and Teti 2002, 372)

• Cry out or follow after a parent when dropped off at the child care program. (6–9 mos.; Ainsworth1967, 4)

• Lift her arms to be picked up by the special infant care teacher. (8 mos.; Meisels and others 2003, 17; Ainsworth 1967, 5)

• Crawl toward a parent when startled by a loud noise. (8.5 mos.; Marvin and Britner 1999, 52)

• Turn excitedly and raise his arms to greet a family member at pick-up time. (8 mos.; Ainsworth 1967, 5)

18 months

At around 18 months of age, children feel secure exploring the environ­ ment in the presence of important adults with whom they have devel­ oped a relationship over an extended period of time. When distressed, children seek to be physically close to these adults. (6–18 mos.; Mar­ vin and Britner 1999, 52; Bowlby 1983)

For example, the child may:

• Run in wide circles around the outdoor play area, circling back each time and hug the legs of the infant care teacher before running off again.

• Snuggle with the special infant care teacher when feeling tired or grumpy.

• Wave at the special infant care teacher from the top of the slide to make sure he is watch­ ing.

• Follow a parent physi­ cally around the room.

• Play away from the infant care teacher and then move close to him from time to time to check in. (12 mos.; Davies 2004, 10)

36 months

At around 36 months of age, when explor­ ing the environment, from time to time children reconnect, in a variety of ways, with the adult(s) with whom they have de­ veloped a special relationship: through eye contact; facial expressions; shared feelings; or conversations about feelings, shared activities, or plans. When distressed, chil­ dren may still seek to be physically close to these adults. (By 36 mos.; Marvin and Britner 1999, 57)

For example, the child may:

• Feel comfortable playing on the other side of the play yard away from the infant care teacher, but cry to be picked up after falling down. (24–36 mos.; Lamb, Bornstein, and Teti 2002, 376)

• Call “Mama!” from across the room while playing with dolls to make sure that the moth­ er is paying attention. (24–36 mos.; Schaffer and Emerson 1964)

• Call for a family member and look out the window for him after being dropped off at school. (24–36 mos.; Marvin and Britner 1999, 56)

• Communicate, “This is our favorite part” when reading a funny story with the infant care teacher.

• Bring the grandmother’s favorite book to her and express, “One more?” to see if she will read one more book, even though she has just said, “We’re all done reading. Now it’s time for nap.” (Teti 1999; 18–36 mos.; Marvin and Britner 1999, 59)

• Cry and look for the special infant care teacher after falling.

• Seek the attention of the special infant care teacher and communicate, “Watch me!” be­ fore proudly displaying a new skill.

At around eight months of age, children show interest in familiar and unfamiliar peers. Children may stare at another child, explore another child’s face and body, and respond to siblings and older peers. (8 mos.; Meisels and others 2003)

For example, the child may:

• Watch other children with inter­ est. (8 mos.; Meisels and others 2003)

• Touch the eyes or hair of a peer. (8 mos.; Meisels and others 2003)

• Attend to a crying peer with a serious expression. (7 mos.; American Academy of Pediat­ rics 2004, 212)

• Laugh when an older sibling or peer makes a funny face. (8 mos.; Meisels and others 2003)

At around 18 months of age, children engage in simple back-and-forth interactions with peers for short periods of time. (Meisels and others 2003, 35)

For example, the child may:

• Hit another child who takes a toy. (18 mos.; Meisels and oth­ ers 2003, 35)

• Offer a book to another child, perhaps with encouragement from the infant care teacher. (18 mos.; Meisels and others 2003, 35)

• Tickle another child, get tickled back, and tickle him again. (18 mos.; Meisels and others 2003, 35)

• Engage in reciprocal play, such as run-and-chase or offer-and­ receive. (12–13 mos.; Howes 1988, v; 10–12 mos.; Ross and Goldman 1977)

• Play ball with a peer by rolling the ball back and forth to each other. (12–15 mos.; Parks 2004; 9–16 mos.; Frankenburg and others 1990)

At around 36 months of age, children engage in simple cooperative play with peers. (36 mos.; Meisels and others 2003 70)

For example, the child may:

• Communicate with peers while digging in the sandbox together. (29–36 mos.; Hart and Risley 1999, 124)

• Act out different roles with peers, sometimes switching in and out of her role. (By 36 mos.; Segal 2004, 44)

• Build a tall tower with one or two other children. (36 mos.; Meisels and others 2003, 70)

• Hand a peer a block or piece of railroad track when building.

• Fuss to communicate needs or wants; begin to cry if the infant care teacher does not respond soon enough. (11–19 mos.; Hart and Risley 1999, 77)

• Repeat sounds to get the infant care teacher’s attention. (11–19 mos.; Hart and Risley 1999, 79)

Behaviors leading up to the foundation (�� to �� months)

During this period, the child may:

• Continue to rely on adults for reassurance and help in con­ trolling feelings and behavior. (Lally and others 1995)

• Reenact emotional events in play to try to gain mastery over these feelings. (Greenspan and Greenspan 1985)

• Use words to ask for specific help with regulating emotions. (Kopp 1989)

• Express wants and needs verbally; for example, say, “hold me” to the infant care teacher when feeling tired or over­ whelmed. (30–31.5 mos.; Parks 2004, 130)

��

Foundation: Impulse Control The developing capacity to wait for needs to be met,

to inhibit potentially hurtful behavior, and to act according to social expectations, including safety rules

8 months

At around eight months of age, children act on impulses. (Birth–9 mos.; Bronson 2000b, 64)

For example, the child may:

• Explore the feel of hair by pulling it. (4–7 mos.; American Academy of Pediatrics 2004, 226)

• Reach for an interesting toy that another child is mouthing.

• Reach for another child’s bottle that was just set down nearby.

• Turn the head away or push the bottle away when finished eat­ ing (8 mos.; Meisels and others 2003, 19).

Chart continues on next page.

18 months

At around 18 months of age, children respond positively to choices and limits set by an adult to help control their behavior. (18 mos.; Meisels and others 2003, 34; Kaler and Kopp 1990)

For example, the child may:

• Stop drawing on the wall when a parent asks. (18 mos.; Meisels and others 2003)

• Choose one toy when the infant care teacher asks, “Which one do you want?” even though the child really wants both.

• Express “no no” while ap­ proaching something the child knows she should not touch, because the infant care teacher has communicated “no no” in the past when the child tried to do this.

• Look to the infant care teacher to see his reaction when the child reaches toward the light switch.

• Stop reaching for the eyeglass­ es on the infant care teacher’s face when she gently says, “no no.” (Scaled score of 10 for 7:16–8:15 mos.; Bayley 2006, 87; 12 mos.; Meisels and others 2003, 27)

36 months

At around 36 months of age, children may sometimes exercise voluntary control over actions and emotional expres­ sions. (Bronson 2000b, 67)

For example, the child may:

• Jump up and down on the couch but stop jumping and climb down when a parent enters the room. (36 mos.; Meisels and others 2003)

• Experience difficulty (e.g., cry, whine, pout) with transitions. (30–36 mos.; Parks 2004, 320)

• Begin to share.

• Handle transitions better when prepared ahead of time or when the child has some control over what happens.

• Touch a pet gently without needing to be reminded.

• Wait to start eating until others at the table are also ready.

Impulse Control

Behaviors leading up to the foundation (� to � months)

During this period, the child may:

• Cry when hungry or tired.

• Fall asleep when tired.

Behaviors leading up to the foundation (� to �� months)

During this period, the child may:

• Crawl too close to a younger infant lying nearby.

• Refrain from exploring another baby’s hair when reminded to be gentle. (8–10 mos.; Brazel­ ton 1992, 256)

• Look at the infant care teacher’s face to determine whether it is all right to play with a toy on the table. (12 mos.; Meisels and others 2003, 25)

• Bite another child who takes a toy.

• Reach for food on a plate before the infant care teacher offers it. (12 mos.; Meisels and others 2003, 25)

Behaviors leading up to the foundation (�� to �� months)

During this period, the child may:

• Begin to use words and dra­ matic play to describe, under­ stand, and control impulses and feelings. (Lally and others 1995)

• Communicate, “Mine!” and take a doll out of the hands of a peer. (23–24 mos.; Parks 2004, 330)

• Throw a puzzle piece on the floor after having trouble fitting it in the opening. (24 mos.; Meisels and others 2003)

• Open the playground door and run out, even after being asked by the infant care teacher to wait. (24 mos.; Meisels and others 2003)

• Start to take another child’s toy, then stop after catching the eye of the infant care teacher. (24 mos.; Meisels and others 2003)

• Use a quiet voice at naptime. (30 mos.; Meisels and others 2003)

• Understand and carry out simple commands or rules. (Bronson 2000b, 85)

• Have a tantrum rather than attempt to manage strong feel­ ings. (Brazelton 1992)

• Be able to wait for a turn.

Foundation: Social Understanding The developing understanding of the responses, communication,

emotional expressions, and actions of other people

8 months

At around eight months of age, children have learned what to expect from familiar people, understand what to do to get another’s attention, engage in back-and-forth interactions with others, and imitate the simple actions or facial expressions of others.

For example, the child may:

• Smile when the infant care teacher pauses, to get her to continue playing peek-a-boo or pat-a-cake.

• Squeal in anticipation of the infant care teacher’s uncover­ ing her eyes during a game of peek-a-boo.

• Learn simple behaviors by imi­ tating a parent’s facial expres­ sions, gestures, or sounds.

• Try to get a familiar game or routine started by prompting the infant care teacher.

• Quiet crying upon realizing that the infant care teacher is ap­ proaching.

18 months

At around 18 months of age, children know how to get the infant care teacher to respond in a specific way through ges­ tures, vocalizations, and shared attention; use another’s emo­ tional expressions to guide their own responses to unfamiliar events; and learn more com­ plex behavior through imitation. Children also engage in more complex social interactions and have developed expectations for a greater number of familiar people.

For example, the child may:

• Gesture toward a desired toy or food while reaching, making imperative vocal sounds, and looking toward the infant care teacher.

• Seek reassurance from the infant care teacher when unsure about something.

• Vary response to different infant care teachers depending on their play styles, even before they have started playing; for example, get very excited upon seeing an infant care teacher who regularly plays in an exciting, vigorous manner.

• Engage in back-and-forth play that involves turn-taking, such as rolling a ball back and forth.

• Look in the direction of the infant care teacher’s gesturing or point­ ing.

• Learn more complex behaviors through imitation, such as watching an older child put toys together and then doing it.

36 months

At around 36 months of age, children can talk about their own wants and feelings and those of other people, describe familiar routines, participate in coordinated episodes of pretend play with peers, and interact with adults in more complex ways.

For example, the child may:

• Name own feelings or desires, explicitly contrast them with another’s, or describe why the child feels the way he does.

• Describe what happens during the bedtime routine or another familiar everyday event.

• Move into and out of pretend play roles, tell other children what they should do in their roles, or extend the sequence (such as by asking “Wanna drink?” after bringing a pre­ tend hamburger to the table as a waiter).

• Help the infant care teacher search for a missing toy.

• Talk about what happened during a recent past experi­ ence, with the assistance of the infant care teacher.

• Help the infant care teacher clean up at the end of the day by putting the toys in the usual places.
