In three experiments, one-year-old infants were observed responding to mechanical, noise-making toys that operated predictably or unpredictably. Interest centered on (1) whether increasing temporal predictability would reduce distress, (2) causes of reduction in distress, and (3) the role of information about the onset of each bout of stimulation…

The facial expressions of twenty-eight 13-month-old middle-class children were videotaped during the 3-minute separation episode of the Ainsworth strange-situation procedure. Anger was the dominant negative emotion expressed by the majority of children; patterns of emotion expression varied with type of attachment; and the proportion of time anger…

Examined whether an infant's reaction to a stranger would be indirectly influenced by the infant observing a stranger-third party interaction. Subjects were 45 15-month-old infants. Results suggest indirect effects influence social interactions and show that significant others can play an important role in mediating these effects. (Author/RH)

When mothers of 12 infants 10 weeks of age displayed noncontingent, practiced facial and vocal expressions of joy, anger, and sadness, infants responded differently to each expression. Infants' matching responses to maternal affects were only part of complex but predictable behavioral patterns that indicate meaningful affect states and possibly…

Videotape study of preschool children, two to five years of age, and adults who posed the six facial expressions of happiness, surprise, anger, fear, sadness, and disgust. Poses were scored using the MAX system. Results showed that consistent differences between partial and complete poses were observed for negative expressions. (Author/RWB)

Analyzes the moral acts of 19 dyads of 4-year-olds in a cognitively simplified version of the Prisoner's Dilemma Game in relationship to their friendship, emotions, and processes of conflict resolution. (HOD)

To investigate affective and dispositional factors in the motivation of children's helping, 60 children ranging from preschool to sixth grade were observed in laboratory distress incidents. Results indicated that helping tended to be positively correlated with positive affect and negatively correlated with negative and neutral affect. (Author/RH)

A developmental model of story liking predicts that (1) reader identification increases with greater perceived similarity between character and reader; (2) increased identification leads to greater suspense; (3) liking of story outcome is a joint function of character valence and outcome valence; and (4) overall liking of story increases with…

Preschool, third-grade and sixth-grade children, and adults were shown vignettes depicting eight types of experiences and asked for their own (for children) or the children's (for adults) expected emotional reactions. Overall, adults showed an absence of developmental considerations in their implicit theories of children's emotional…

Investigates a proposed four-stage developmental sequence that describes how children explain changes in sad and angry feelings and how their ability to understand is related to their theories of how feelings change. (HOD)

Distress in response to brief maternal separations was examined in a sample of 93 predominantly home-reared infants using the Ainsworth strange situation paradigm. At 18 months, the age when separation protests begin to decline, securely attached infants are better able than anxiously attached infants to tolerate maternal separations. (Author/RH)

Involving 82 preschool children and grade 2 students, a study was conducted to (1) determine whether heart rate, facial, and self-report indices could be used to differentiate between different vicariously induced negative emotional states; (2) examine developmental differences in the degree of differentiation; and (3) assess the pattern of…

Compares the separation distress of 26 19-month-old Downs Syndrome infants in the Strange Situation with that of 43 normal infants who were observed at 12 1/2 and 19 1/2 months to assess whether Downs Syndrome infants responded more similarly to cognitively comparable normals than to age-comparable normals. (HOD)

First-, third-, fifth-, and tenth-grade children listened to eight stories designed to elicit prosocial or self-protective display rules. Children predicted protagonists' verbal and facial expressions to emotion-laden situations. Findings indicated knowledge of control of emotional displays increases between first and fifth grades, but then levels…
