Early adolescence represents a particularly vulnerable period of development during which young people are susceptible to establishing lifelong behavior patterns associated with poor life, health, and educational outcomes. Previous research demonstrates older adolescents and young adults often experience negative life events (NLEs) prior to…

As education continues to integrate technological advancements into learning and instruction, a resource dedicated to the latest findings and implications becomes necessary. This handbook provides academicians, researchers, and practitioners with a comprehensive view of the historical, conceptual, theoretical, and practical perspectives of…

Research indicates that mental health social workers risk being confronted with fatal and nonfatal client suicidal behaviors during professional practice. Although reactions to client suicidal behavior have been documented, there is little empirical evidence about coping behaviors and available supports following client suicidal behavior. This…

The estimation processes used by fifth through eighth grade students as they responded to computational estimation test items were examined. Interview-based process descriptions were cross-validated using large group test data from an open-ended test and a multiple choice test. Five question formats were used to test different estimation…

To document movement patterns and to examine developmental interrelationships, the ontogeny of rooting, lip, lateral tongue, mouth opening, biting, and Babkin reflexes and the development of emerging chewing behaviors were observed in two normal infants over a period from 1 week to 35 weeks of age.

The emotional impact of televised interpersonal dramas was investigated, with specific emphasis being given to age- and gender-related differences in children's spontaneous nonverbal expressive reactions. Participants were 27 female and 22 male children in three age groups: 4-5, 7-8, and 13-14 years. Facial expressions were unobtrusively…

Two studies examined the relationship between cognitive rigidity and cognitive inertia, with a total of 52 children and adults with mental retardation and 50 nonretarded individuals. Findings provide some support for the theory that there are age-related inherent structural differences leading to greater rigidity in older adults. (DB)

Three studies explored age, sex, and individual differences in children's defensiveness about four feelings: happiness, anger, sadness, and fear. Also investigated was the relation between children's defensiveness and their mothers' comfort with and expression of feelings. Participants included children ranging in age from 4 through 11 years of…

This study examined age and sex differences in young children's skills in decoding nonverbal facial cues of emotional states. The purpose was threefold: (1) to determine whether older preschoolers were better decoders than younger preschoolers; (2) to see whether sex differences would be apparent throughout the preschool period or emerge only…

Following World War I, researchers began to study psychological and behavior problems resulting from war experiences. Today these problems are defined as Posttraumatic Stress Disorders (PTSD). The PTSD problems of Vietnam veterans have been widely reported but less is known about World War II and Korean veterans. A study was undertaken to examine…

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…

Tests two hypotheses concerning developmental change in the speed of cognitive processes: (1) age differences in processing time reflect changes that are specific to particular tasks, and (2) age differences in processing speed do not reflect task-specific change but are due instead to more general developmental change. (HOD)

Investigates to what extent discrimination learning through time delay of multistimulus, distinctive-feature prompts is a function of the inclusion and configuration of the S-prompt. Results of two experiments with children aged four and five indicate that most subjects did not learn the task assigned unless two distinctive-feature prompts were…

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…
