A reanalysis of Stephens' intercorrelations of Wechsler subtests, achievement tests, and Piagetian tasks was conducted. (EJ 055 112) Piagetian tasks contributed almost equally to the definition of the general factor in intelligence along with the Wechsler subtests and the achievement tests. Communality outweighed differences between intelligence…

Two experiments were conducted to study the development of mental rotation abilities in late childhood, adolescence, and adulthood. Subjects were third, fourth, and sixth graders, and college students. (MP)

Discusses the main language policies that have been implemented in the Peoples' Republic of China since 1949 and presents the learning experiences of six learners differing in age and language backgrounds. Suggests individual learning histories reflect the policy changes. (Author/VWL)

Examined developmental and individual differences in tendencies to favor analytic over heuristic responses in three tasks (inductive reasoning, deduction under belief bias conditions, probabilistic reasoning) in children varying in age and cognitive ability. Found significant increases in analytic responding with development on first two tasks.…

Examined the role of individual differences in working memory and lexical access in age- and reading skill-related differences in performance on phonological synthesis tasks. The performance of 28 kindergarten, first-, and second-grade students with normal reading skills, and that of 28 reading-disabled second graders, was compared under four…

Examined Swedish children's inhibition behavior using mothers' and psychologists' ratings of inhibition at age 18 and 24 months to predict later ratings through age 16 years. Prediction was more reliable for children rated as very inhibited or very uninhibited than for those in nonextreme group through age six. Only for inhibited girls did early…

Three studies explored age changes and individual differences in preschoolers' sustained attention in different contexts. Found that changes occurred earlier for play and television viewing than for reaction time tasks. Results suggest that children have stable tendencies to sustain attention but that attention varies with task demands and…

Examined mothers' and preschoolers' emotion talk for age- and gender-related patterns in use of labels and explanations. Found that children used emotion words mainly in labels. Boys' emotion talk increased with age. The youngest girls had more emotion talk than same-age boys. Mothers used more explanations than labels with boys but similar…

Examined impact of phonological-awareness training with or without explicit attention to articulation and with or without manipulation of sounds. Subjects were 7- to 11-year olds with reading difficulties. Found that children in all training conditions outperformed controls on all tests except math. Individual differences in response related to…

Used time-lapse video to record sleep/wake states of preterm infants for three 24-hour periods at 33 and 35 weeks conceptional age. Found that very-low-birthweight preterm infants showed marked stability and developmental change in the organization of sleep/wake states from a very early age, and their states were related to demographic variables…

Background: The international literature has documented that self-determination is impacted by environmental factors, including living or work settings; and by intraindividual factors, including intelligence level, age, gender, social skills and adaptive behaviour. In addition, self-determination has been correlated with improved quality of life…

A study explored girls' emerging attitudes toward breast care and breast self-exam (BSE) and the extent to which girls had given thought to these issues. Analyses focused specifically on individual differences related to age, stage of breast development, perceived normalcy of breast development, and body image. The sample consisted of 43 white,…

An investigation was made of the relationships between creativity and factors associated with the aging process of retired and current artists over the age of 65. Its focus was to determine differences among three groups of creative people--continuing artists, retired artists, and new artists--in terms of their views of how aging affects…

This technical report describes a series of three studies designed to instruct students in the relationship between texts, comprehension questions, and two sources of answer information--the text to which a given question refers and their own background knowledge. The focus of the technical report is on individual differences in the amount and…

This report examines: (1) the extent to which rural school administrators personally use microcomputers for administrative tasks; (2) whether such use is determined by differences in sex, age, size of school district, and type of administrative assignment; and (3) the kinds of administrative computer applications that are most prevalent. Subjects…
