The systematic literature review is based on a critical need in the area of values, where there are many uncertainties around universal definitions and drivers of values and traits. The study evaluated definitions, categories, drivers and the interdependence between values and personality traits and behaviours. Over 5,873 studies over a 70-year…

The goal of this article was to examine gender-typed behavior longitudinally and to consider its relationship with sexual orientation in adulthood. Data were from 10,624 respondents who completed Wave 1 (adolescence), Wave 3 (emerging adulthood), and Wave 4 (early adulthood) of the National Longitudinal Study of Adolescent to Adult Health. First,…

Research has supported the existence of distinct behavioral patterns, demographic correlates, and etiologic mechanisms for aggressive (AGG) versus nonaggressive but delinquent (DEL) antisocial behavior. Though behavioral genetic studies have the potential to further crystallize these dimensions, inconsistent results have limited their…

It has been hypothesized that sensation seeking and impulsivity, which are often conflated, in fact develop along different timetables and have different neural underpinnings, and that the difference in their timetables helps account for heightened risk taking during adolescence. In order to test these propositions, the authors examined age…

In a study involving 101 severely developmentally disabled children (1-16 years old), stereotyped behaviors without objects was positively correlated with self-manipulation and chronological age and was negatively correlated with complex object manipulation, developmental age, developmental quotient, and teacher attention. Stereotyped behavior…

Examined whether graduate students (N=40) experienced developmental transitions similar to those suggested in adult development theories by using a structured interview protocol to collect data on developmental tasks. Findings indicated that the developmental transitions reflected in a composite developmental framework were applicable to graduate…

Presents a developmental study of changes in infant attachment behaviors. Five groups of female infants, 8, 11, 14, 19, and 24 months of age, were observed during varying types of separation experiences. Changes in proximity behaviors and contact behaviors were analyzed. (BD)

Assessed Type A behavior pattern for 122 teenagers who had heart rate measured during rest and presentation of mental arithmetic stressor under timed and competitive conditions. Examined whether sex, age, task performance, and behavior pattern predicted heart rate reactivitiy. Found no significant main effects for behavior pattern, sex, or age;…

Competence in action perception seems to be achieved very early in life. Because research has indicated that competent perceivers of action must be able to discriminate breakpoints in behavior, then recognition memory for breakpoints should be superior to that for nonbreakpoints at all ages where competence in action perception exists. Two studies…

Describes the compliance-resisting behaviors in selected communication by first-, fourth-, and tenth-grade students. Seeks to assess the development of ability to construct compliance-resisting strategies. (MS)

Reviews and integrates several aspects of peer interaction in the infant/toddler period. Reveals convergence between age-related changes in social skills and similarly timed cognitive developments. (HOD)

Compared coupling characteristics of clapping simultaneous with walking or galloping, consistency across trials, and phasing variability among 4-, 6-, 8-, and 10-year-olds. Found that for walk/clap tasks, children adopted adult-like coupling patterns by age 8 and with the same consistency by age 10. Across age, children became less variable in…

Interpretation of experimental tasks is influenced by knowledge of the language used, by assessment of what the experimenter intends, and by how subjects themselves would normally represent the physical situation. Whether these processes in which children engage in cognitive studies differ from those employed by adults in similar tasks was…

Examined the ability of three-year-olds, four-year-olds, kindergartners, and second graders to predict how certain internal and external conditions affect behavior. In two studies, a forced-choice procedure revealed that even the youngest group could predict the effect of various causes, while a third study examined more complex types of causal…

Developmental changes in specific types of fantasy play and the relation of role taking, egocentrism, and receptive vocabulary were examined in two- to six-year-olds. Both frequency and duration of material and ideational fantasy play increased with age, but play patterns differed. Data suggest developmental progression from object to person…
