Adult literacy skills are critical assets of individuals as well as societies in terms of economic (e.g., human capital) and social well-being. Thus, it is important to monitor the long-term trends and sources of skill gain/loss. Yet, temporal sources of adult literacy skill variation are understudied. The current study analyzed three comparable,…

The rising costs of recruiting and hiring workers and the seismic shift of age demographics in the United States workforce has created much stir around the concept of generational cohorts. Although much has been done by researchers and practitioners alike to attempt a better understanding of each generational group's leadership preferences,…

We studied the effect of the number and characteristics of siblings (sex, age) on school achievement in several grades (kindergarten, first grade, and fifth grade), in two large French cohorts, with more than 16,000 children. Running linear mixed-effects models, we find that, independently of socioeconomic status, having more siblings is…

This longitudinal study examined developmental changes in conflict inhibition and error correction in three cohorts of children (5, 7, and 9 years of age). At each point of assessment, children completed three levels of Luria's tapping task (1980), which requires the inhibition of a dominant response and maintenance of task rules in working…

Life Span psychological and life course sociological perspectives have long acknowledged that individual functioning is shaped by historical and sociocultural contexts. Secular increases favoring later-born cohorts are widely documented for fluid cognitive performance and well-being (among older adults). However, little is known about secular…

In this study, the values of students in the physical education and sport departments were examined according to their gender, age, grade, and departments. The questionnaire method was used in the study. As the data collection tool, the Portrait Values Questionnaire was applied. The study group consisted of a total of 389 students 126 of whom were…

The present study used a cohort-sequential design to examine developmental changes in children's ability to bind items in memory during early and middle childhood. Three cohorts of children (aged 4, 6, or 8 years) were followed longitudinally for 3 years. Each year, children completed a source memory paradigm assessing memory for items and…

Maternal education captured at a single time point is commonly employed as a predictor of a child's cognitive development. In this article, we ask what bearing the acquisition of additional qualifications has upon reading performance in middle childhood. This was a secondary analysis of the United Kingdom's Millennium Cohort Study, a cohort of…

This study was designed to analyze the relationship of students' learning motivation and their academic performances in science. The study made use of 21 junior and senior Biological Science students to conclude on the formulated research problems. The respondents had a good to very good motivation in learning science. In general, the extent of…

The current study demonstrates the application of an analytic approach for incorporating multiple time trends in order to examine the impact of cohort effects on individual trajectories of eight drugs of abuse. Parallel analysis of two independent, longitudinal studies of high-risk youth that span ages 10 to 40 across 23 birth cohorts between 1968…

In Western cultures, life narratives are typically expected to recount the narrator's life from birth to the present. Disparate autobiographical memories need to be integrated into a more or less coherent story, which is facilitated by an overarching temporal macrostructure. The temporal macrostructure consists of elaborated beginnings that…

The Supports Intensity Scale-Children's Version (SIS-C)was developed to assess the support needs of children and youth aged 5 to 16 years with intellectual and developmental disabilities. Data from the standardization sample of the SIS-C were analyzed to evaluate the impact of the age cohorts (5-6, 7-8, 9-10, 11-12, 13-14, and 15-16 years) used to…

The ability to narrate stories and a synchronic self-concept develop in the pre- and primary school years. Life story theory proposes that both developments extend to an even later developmental stage, that is, to adolescents' acquisition of a coherent life story. Cross-sectional evidence supports the emergence of a life story in adolescence, but…

This paper evaluated age differences in emergency department care and inpatient hospitalizations in 252 preadolescent and adolescent youth with autism spectrum disorders (ASDs; ages 9-18). Records from youth with ASDs were linked to acute care utilization records and were compared to a demographically similar comparison group of youth without ASDs…
