Prior knowledge and subtyping effects in children's category learning

Two experiments examined how 5- and 10-year-old children revise their category representations when exposed to exemplars that are congruent or incongruent with existing knowledge. During training children were presented with exemplars containing features that were congruent or incongruent with children's social stereotypes together with a stereotype-neutral feature. In the knowledge-subtyping condition this neutral feature predicted the stereotype-congruence of the other features. In the knowledge-standard condition the neutral feature was uncorrelated with stereotype-congruence. At test children made judgements about feature co-occurrence within the learned category. In each experiment these judgements were influenced by both stereotypical beliefs and exemplar observation. Stereotypical beliefs, however, had a greater influence on co-occurrence judgements in the knowledge-subtyping than in the standard conditions. In Experiment 2 these effects were shown to generalize to judgements about features that were not presented during training. These results challenge current models of knowledge-based categorization by showing that exemplar structure determines whether novel exemplar features are incorporated into category representations.     

Tridimensional personality traits of college student marijuana users

The present study examined the possibility that marijuana use among college students might be associated with particular personality traits. College student volunteers (N = 176) were administered the Tridimensional Personality Questionnaire and a drug-use questionnaire. Analysis of variance showed that the mean score on Novelty Seeking was significantly higher and on Persistence significantly lower among lifetime marijuana users than among nonmarijuana using peers. Programs for prevention among college students may be enhanced by approaches tailored to individuals scoring high on Novelty Seeking and low on Persistence.     

Within-Person Variability in Goal Content and Goal Frame: Amount,Patterns, Antecedents,and Consequences of Variation in Goal Orientation Over Time

Several studies have examined goal fluctuation over time, focusing on variability in goal level. This study investigated within-person variation in goal content and goal frame. Drawing from Motivated Action Theory (DeShon & Gillespie, 2005 DeShon, R. P. and Gillespie, J. Z. 2005. A motivated action theory account of goal orientation. Journal of Applied Psychology, 90: 1096–1127. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) we examined variability in goal orientation over time in terms of amount, patterns, antecedents, and consequences. Participants completed a dispositional goal orientation measure and then daily surveys assessing perceptions, behavior, and goal orientation prior to a single performance episode. Results indicated there was substantial within-person variability, there were patterns in this variability involving goal-related behaviors and dispositional goal orientation, and certain patterns predicted exam performance. These findings suggest it may be useful to focus on not only goal level but also goal content and goal frames in future goal regulation research.     

Abstracting Sequences: Reasoning That Is a Key to Academic Achievement

The ability to understand sequences of items may be an important cognitive ability. To test this proposition, 8 first-grade children from each of 36 classes were randomly assigned to four conditions. Some were taught sequences that represented increasing or decreasing values, or were symmetrical, or were rotations of an object through 6 or 8 positions. Control children received equal numbers of sessions on mathematics, reading, or social studies. Instruction was conducted three times weekly in 15-min sessions for seven months. In May, the children taught sequences applied their understanding to novel sequences, and scored as well or better on three standardized reading tests as the control children. They outscored all children on tests of mathematics concepts, and scored better than control children on some mathematics scales. These findings indicate that developing an understanding of sequences is a form of abstraction, probably involving fluid reasoning, that provides a foundation for academic achievement in early education.     

To Jim,from Fiji

A braided epistolary essay, “To Jim, from Fiji,” explores three kinds of relationships: how musicians share music; the relationship of an artist to art itself; and human interaction with the divine via music. The article begins as a personal letter to the writer's Jungian therapist, then tells the story of a trip to Fiji, where music became the entryway to a deep and connective experience. The sections weave together to develop an inquiry into how humans use music to relate with each other and with a numinous reality, where the artist can become “vassal and vessel both.”     

The influence of perceived accountability and outcome interdependence on goals and effort

Self‐regulatory processes are central to achievement contexts, as individuals spend much of their time in these situations pursuing goals. This study investigated the effects of accountability and outcome interdependence on goal and effort regulation over time. Participants completed five task trials, reporting goals and intended effort prior to each trial and receiving performance feedback after each trial. Hierarchical linear modeling analyses indicated that there was a positive within‐person relationship between performance and subsequent goals. More importantly, findings indicated that the performance–goal relationship was moderated by accountability and the performance–effort relationship was moderated by outcome interdependence. These results reveal that the goal and effort regulation patterns observed in prior studies are influenced by common social contextual factors, leading to different patterns of self‐regulation.     

On individual differences in person perception: raters' personality traits relate to their psychopathy checklist-revised scoring tendencies

This study investigated raters' personality traits in relation to scores they assigned to offenders using the Psychopathy Checklist-Revised (PCL-R). A total of 22 participants, including graduate students and faculty members in clinical psychology programs, completed a PCL-R training session, independently scored four criminal offenders using the PCL-R, and completed a comprehensive measure of their own personality traits. A priori hypotheses specified that raters' personality traits, and their similarity to psychopathy characteristics, would relate to raters' PCL-R scoring tendencies. As hypothesized, some raters assigned consistently higher scores on the PCL-R than others, especially on PCL-R Facets 1 and 2. Also as hypothesized, raters' scoring tendencies related to their own personality traits (e.g., higher rater Agreeableness was associated with lower PCL-R Interpersonal facet scoring). Overall, findings underscore the need for future research to examine the role of evaluator characteristics on evaluation results and the need for clinical training to address evaluators' personality influences on their ostensibly objective evaluations.     

Sun protective behaviour,optimism bias,and the transtheoretical model of behaviour change

This study investigated the relationship between sun protective behaviours and three psychological variables influencing health behaviour: decisional balance, optimism bias, and the transtheoretical model of behaviour change. Two hundred participants completed the ‘Readiness to Alter Sun Protective Behaviour’ questionnaire, and a short questionnaire investigating optimism bias, decisional balance, attitudes, and experiences of sun protection and skin cancer. Participants were evenly distributed between the precontemplation, contemplation, and action stages. Participants in the action stage were significantly more likely to endorse the perceived advantages associated with sun protective behaviour than participants in the precontemplation and contemplation stages. They also reported sunbathing significantly less—and being more concerned about contracting skin cancer—than participants in the earlier stages. Decisional balance and optimism bias scores varied systematically across the stages of change; however, decisional balance was the only significant psychological predictor of sun protective behaviours. Optimism bias was greatest in the precontemplation stage, whereas the action stage was characterised by more positive attitudes to sun protection. This suggests that knowledge of the real risks of skin cancer might be a precursor to behaviour change, but only a change in attitudes results in a move to the action stage and measurable behaviour change.
