Feeling inhibited and socially not at ease is reflected in the trait social inhibition (SI). SI is associated with psychopathology that arises in young adulthood, such as anxiety. We aim for a better insight into the genetic and environmental contributions to SI across the life span, and as such examine their contributions to SI stability and…

Some researchers indicate that the transition to high school deflects adolescent developmental trajectories. Others assert that it provides a new possibility for the promotion of adolescents' socioemotional well-being. One critical view missing in such claims is that individual variabilities interact with environmental influences. We employed the…

According to several developmental theories some children are more sensitive to the quality of their environment than others, but most supporting empirical evidence is based on relatively distal markers of hypothesized sensitivity. This study provides evidence for the validity of behaviorally observed Environmental Sensitivity as a moderator of…

Twin studies find ~20% of the variance in achievement in public examinations taken at age 16 in the United Kingdom can be explained by experiences not shared within families. Nonshared environmental (NSE) influences, including measurement error, explain why monozygotic (MZ) twins differ from each other. Such influences work independently of…

Parental sensitivity and nurturance are important mechanisms for establishing biological, emotional, and social functioning in childhood. Sensitive, nurturing care is most critical during the first three years of life, when attachment relationships form and parental care shapes foundational neural and physiological systems, with lifelong…

Self-perceived abilities (SPA), which play an important role in academic achievement, have been recently reported to be fully attributable to genetic and non-shared environmental influences. To replicate and extend this finding, 732 Croatian twins (15-22 years old) were assessed on cognitive ability, self-assessed intelligence (SAI), and Five…

Investigated how urban elderly spend their days. Obtained detailed time budgets for one full day from 535 persons with differing levels of independence in contrasting environmental settings. Consistent patterns appeared across groups, particularly in the amount of time spent in the various social contexts and in most discretionary activities.…

This paper reviews 35 studies important in the historical development of field dependence, a popular research topic in psychology. The first section involves antecedents of the concept of field dependence, such as the influence of Kurt Lewin. Part two deals with the development of field dependence as an individual differences variable. Part three…

Examined violent and victimized male prisoners (n=942). Identified two types of predatory inmates: those having trouble relating to others and those who were assaultive. Victims lacked experience to cope with environment. Both violent and victimized inmates had distinctive personalities, specific environmental needs, and both rated prison setting…

Previous research provides support for two distinct models of expectation behavior in experimental games. The similarity pattern describes expectations that are similar to the actor's behavior regardless of whether the actor is cooperative or competitive. The triangularity pattern describes expectations that are both similar and dissimilar to…

One way to connect research with its clinical application is to examine the interplay between context and child. This article discusses the relationship between temperamental characteristics and the caregiving environment. During the first year of life, individual temperament differences in newborns are moderately stable and influence the nature…

The current study was designed to examine performance effects and fatigue effects associated with different total SAT testing times. In addition, the researchers examined personality, motivation, and other determinants of individual differences in examinee fatigue before, during, and after testing.
