One widely acknowledged way to improve our memory performance is to repeatedly study the to be learned material. One aspect that has received little attention in past research regards the context sensitivity of this repetition effect, that is whether the item is repeated within the same or within different contexts. The predictions of a…

How do Latino immigrants in the United States understand existing racial categories? And how does the existing U.S. racial order influence this understanding? Using data from the New Immigrant Survey (NIS), our analysis points to changes in how the U.S. racial order might operate in the future. We find that most Latino immigrants recognize the…

In an experiment with 109 undergraduates, we examined the effect of mood, cognitive style, and cognitive ability on implicit learning in the Artificial Grammar (AG) and Serial Reaction Time (SRT) tasks. Negative mood facilitated AG learning, but had no significant effect on SRT learning. Rational cognitive style predicted greater learning on both…

The current study investigated the mechanisms underlying peer contagion of depressive symptoms in adolescence. Five annual measurements of data were gathered from a large (N = 842) community-based network of adolescents (M = 14.3 years at first measurement). Results showed that, after controlling for selection and deselection of friends on the…

Considerable research has examined the contrasting predictions of configural and elemental associative accounts of learning. One of the simplest methods to distinguish between these approaches is the summation test, in which the associative strength of a novel compound (AB) made of two separately-trained cues (A+ and B+) is examined. The…

We explored the meanings that undergraduate students make of their education and how these meanings relate to students' perceived stress, styles of coping with stress, and optimism. Participants completed a meaning of education questionnaire, the Perceived Stress Scale, the COPE (a measure of coping styles), and the Life Orientation Test-Revised.…

Much theorization and research have been done independently on thinking styles and psychosocial development. The primary objective of this research was to further investigate the predictive power of thinking styles for psychosocial development through replicating Zhang and He's (in press) study of Chinese university students in Shanghai, mainland…

In this study, we predicted achievement based on a variety of school demographic and background variables and identified schools that had achievement profiles that exceeded or fell short of their expected achievement levels. We identified schools that were over- or underperforming and surveyed parents, teachers, and administrators in an effort to…

This study reports adolescent expectancy-value motivation, and its relation to fitness knowledge and psychomotor skill learning in physical education. Students (N = 854) from 12 middle schools provided data on expectancy-value motivation, fitness knowledge and psychomotor skill learning. Results from dependent t-test and MANOVA indicated that 8th…

In studies of child development, the combined effect of multiple risks acting in unison has been represented in a variety of ways. This investigation builds upon this preceding work and presents a new procedure for capturing the combined effect of multiple risks. A representative sample of 2,899 British children had their cognitive development…

The aim of this study was to test the direction of effect in the relationship between bullying and empathy. The participants were 205 sixth-grade students, randomly selected from urban and rural schools in Cyprus. A six-month, two-time-point longitudinal design was used in which the participants completed the bullying subscale of the Revised…

Friendships are essential for adolescent social development. However, they may be pursued for varying motives, which, in turn, may predict similarity in friendships via social selection or social influence processes, and likely help to explain friendship quality. We examined the effect of early adolescents' (N = 374, 12-14 years) intrinsic and…

This study examined how the two cerebral hemispheres recruit semantic processing mechanisms by combining event-related potential measures and visual half-field methods in a word priming paradigm in which semantic strength and predictability were manipulated using lexically associated word pairs. Activation patterns on the late positive complex…

In 3 studies (N = 188) we tested the hypothesis that children use a perceptual access approach to reason about mental states before they understand beliefs. The perceptual access hypothesis predicts a U-shaped developmental pattern of performance in true belief tasks, in which 3-year-olds who reason about reality should succeed, 4- to 5-year-olds…

Performance on three verbal measures (story recall, paired associated learning, category fluency) designed to assess the integration of long-term semantic and linguistic knowledge, phonological working memory and executive resources within the proposed "episodic buffer" of working memory (Baddeley, 2007) was assessed in children with intellectual…
