Used Visual Expectation Paradigm to describe information processing changes and individual differences during first year of life. Found regular age changes in mean reaction time and variability but not in minimum reaction time, suggesting that growth rate of sensory-detection information is constant during first year but age changes occur in level…

Speculates on underlying processes for the reaction time variance and age differences in anticipation latency using the Visual Expectation Paradigm. Discusses the dichotomization of reactive and anticipatory behavior, limitations of longitudinal designs, drawbacks in using standard procedures and materials, and inferences that can be made…

Examined two hypotheses regarding activity level: (1) early appearing stability; and (2) inversion of intensity. Measured behavioral intensity or activity level six times between the neonatal period and first grade. Results indicated that parent ratings supported activity level stability. Observations revealed that intense neonatal activity…

In this longitudinal study, 60 mothers rated their toddler's personality traits concerning social relations and exploration of the physical and social world. Data showed that mothers of toddlers from older cohorts were more likely to have stable and consistent, but not more negative, perceptions of their child's personality over six months than…

Forty 3.5- to 4.5-year-olds discussed past events with their mothers and completed tasks indexing their ability to reason about conflicting mental representations and understanding of knowledge. Found that theory-of-mind scores were related to memory conversation participation, independent of age and linguistic skill, and to the frequency of…

Michigan State University's College of Human Medicine has added modules on developmental screening to the second-year medical curriculum, teaching students to specialize their basic interviewing and physical assessment skills by considering the patient's developmental stage as well as age-specific risks, issues, and concerns.

Positively correlated were verbal fluency scores and scores for strategies expected to distinguish levels of verbal fluency among 64 third-graders and 71 sixth-graders. When a smaller sample of similarly aged students completed expanded versions of tasks, results revealed grade and gender differences in strategy use and level of task performance.…

A sample of seventh, ninth, and eleventh graders generated self-descriptors for the role of the self in the classroom, with friends, with parents, and in romantic relationships. Findings revealed that the self becomes increasingly differentiated into role-related multiple selves with age. (GLR)

This study examined the receptive vocabulary of 102 first-, third-, and sixth-grade Spanish/English bilingual students of Hispanic origin. It found that, although students in all three grade levels functioned comparably well on the Spanish instruments, performance on the English instruments increased with grade level.

Examined perceptions of personal control in 1,267 individuals in 4 generations of families participating in multiple cohort, longitudinal study spanning 1971-91. Over 20 years, mean levels of personal control became more internal among 560 individuals who participated in all measurements, probably reflecting environmental factors. Found…

In two experiments, five year olds produced more instances in slot-filler categories than taxonomic categories, and eight year olds produced more instances in taxonomic categories than slot-filler categories; for five year olds, slot-filler categories led to superior recall and shorter response latencies than did taxonomic categories.

Explores the process of personal and social transformation involved in becoming a mature student through the construction of four narratives derived from the biographical accounts of 21 students entering higher education. Demonstrates the gendered nature of conceptions of self in these accounts. Shows that education is a key site for the…

Three samples of 8- to 16-year olds were assessed three times at yearly intervals on eight water-level items. Within-child change over age was viewed as stochastic process of the child changing or remaining in one of three latent strategy states. Although there was improvement in task performance over age, the general finding was that strategy…

Prevelance of self-reported victimization was found to be high, both while youth were in and out of school. Males and younger students reported higher rates of victimization. Males and 9th grade students were more likely to report engaging in delinquent behaviors. Students who report moderate/high levels of delinquency were more likely to report…

Examined visual attention and implications for recognition memory in a longitudinal sample of full-term and preterm infants at 5, 7, and 12 months. Found differences between full-terms and preterms in several aspects of visual attention. Infants showed consistent attentional styles over various conditions. Shorter looks and higher shift rates…
