Effects of proactive interference on non-verbal working memory

Working memory (WM) is a cognitive system responsible for actively maintaining and processing relevant information and is central to successful cognition. A process critical to WM is the resolution of proactive interference (PI), which involves suppressing memory intrusions from prior memories that are no longer relevant. Most studies that have examined resistance to PI in a process-pure fashion used verbal material. By contrast, studies using non-verbal material are scarce, and it remains unclear whether the effect of PI is domain-general or whether it applies solely to the verbal domain. The aim of the present study was to examine the effect of PI in visual WM using both objects with high and low nameability. Using a Directed-Forgetting paradigm, we varied discriminability between WM items on two dimensions, one verbal (high-nameability vs. low-nameability objects) and one perceptual (colored vs. gray objects). As in previous studies using verbal material, effects of PI were found with object stimuli, even after controlling for verbal labels being used (i.e., low-nameability condition). We also found that the addition of distinctive features (color, verbal label) increased performance in rejecting intrusion probes, most likely through an increase in discriminability between content–context bindings in WM.     

Gender‐Based Judgments of Traffic Violations: The Moderating Influence of Car Type1

This paper reports the findings of a study investigating interpretations of driver behavior during a traffic accident. Using authentic road‐accident reports including figurative depictions of the accident and a photograph of the car involved, participants were asked to make judgments of the driver's carelessness and aggression before and during the accident. Contextual factors were manipulated by altering the type of car driven (following Davies, 1999) and the sex of the driver. Results showed that car type influenced the allocation of cause of the accident, with drivers of a BMW being described as having acted more aggressively, and drivers of Smart Cars having been depicted as acting more carelessly, despite the actions of both drivers being held constant. In addition, the actions of the female driver were interpreted as more attributable to driver carelessness than driver aggression or external factors. Results are discussed with reference to car‐type stereotypes. Ways in which such biased interpretations could influence how drivers respond to other road users in real‐life situations are suggested.     

Trajectories of classroom externalizing behavior: Contributions of child characteristics, family characteristics, and the teacher-child relationship during the school transition

The unique and interactive contributions of past externalizing behavior, negative parenting, and teacher-child relationship quality to externalizing behavior trajectories after the transition to school were examined. In a sample of 283 children, random regression analyses indicated that conflict in the teacher-child relationship during the school transition contributed to faster rates of increase in externalizing behavior from kindergarten through third grade above and beyond negative parenting and initial levels of externalizing behavior. A significant interaction between teacher-child closeness and the externalizing behavior intercept indicated that decreases in externalizing behavior were associated with teacher-child closeness, especially for children with the highest levels of externalizing behavior upon school entry. Family socioeconomic status and initial levels of classroom externalizing behavior in kindergarten were also significant contributors to the prediction of externalizing behavior trajectories.     

The supramodal brain: implications for auditory perception

ABSTRACT

The perceptual brain is designed around multisensory input. Areas once thought dedicated to a single sense are now known to work with multiple senses. It has been argued that the multisensory nature of the brain reflects a cortical architecture for which task, rather than sensory system, is the primary design principle. This supramodal thesis is supported by recent research on human echolocation and multisensory speech perception. In this review, we discuss the behavioural implications of a supramodal architecture, especially as they pertain to auditory perception. We suggest that the architecture implies a degree of perceptual parity between the senses and that cross-sensory integration occurs early and completely. We also argue that a supramodal architecture implies that perceptual experience can be shared across modalities and that this sharing should occur even without bimodal experience. We finish by briefly suggesting areas of future research.     

Deriving childhood temperament measures from emotion-eliciting behavioral episodes: scale construction and initial validation

The authors describe the development and initial validation of a home-based version of the Laboratory Temperament Assessment Battery (Lab-TAB), which was designed to assess childhood temperament with a comprehensive series of emotion-eliciting behavioral episodes. This article provides researchers with general guidelines for assessing specific behaviors using the Lab-TAB and for forming behavioral composites that correspond to commonly researched temperament dimensions. We used mother ratings and independent postvisit observer ratings to provide validity evidence in a community sample of 4.5-year-old children. 12 Lab-TAB behavioral episodes were employed, yielding 24 within-episode temperament components that collapsed into 9 higher level composites (Anger, Sadness, Fear, Shyness, Positive Expression, Approach, Active Engagement, Persistence, and Inhibitory Control). These dimensions of temperament are similar to those found in questionnaire-based assessments. Correlations among the 9 composites were low to moderate, suggesting relative independence. As expected, agreement between Lab-TAB measures and postvisit observer ratings was stronger than agreement between the Lab-TAB and mother questionnaire. However, for Active Engagement and Shyness, mother ratings did predict child behavior in the Lab-TAB quite well. Findings demonstrate the feasibility of emotion-eliciting temperament assessment methodologies, suggest appropriate methods for data aggregation into trait-level constructs and set some expectations for associations between Lab-TAB dimensions and the degree of cross-method convergence between the Lab-TAB and other commonly used temperament assessments.     

Willingness to date across race: differences among gay and heterosexual men and women

Willingness to date members of other races was examined among 200 men with same-sex dating preference (n = 100) and opposite-sex dating preference (n = 100), and 200 women with same-sex dating preference (n = 100) and opposite-sex dating preference (n = 100) who were randomly selected from an Internet dating web site. Overall, results indicated a greater willingness among gay participants than heterosexual participants to date people of other races. A 2 (Sex) x 2 (Sexual Orientation) analysis of variance showed an interaction, with lesbian women more willing to date other races than gay men, while among heterosexual participants men were more willing than women to date other races. The role of mate selection theory, and the importance of the status afforded various races in U.S. society, were applied to interpret people's willingness to date other races.     

The Disappearance of Adulthood

In 1982, Neil Postman wrote The Disappearance of Childhood. In that work, Postman recounted the invention of childhood in the modern world and its demise at the hands of, among other things, the electronic media (principally television). In Postman’s view, television had transformed education into ‘edutainment.’ The implications of this loss were devastating. Taking up where Postman left off I wish to reexamine his claim and amend and update his thesis by suggesting that, after the latest electronic turn, we now live in societies where a meaningful conception of adulthood is disappearing. It is disappearing, in part, because of an impoverished conception of citizenship. Yet it is additionally undermined because, claims to the ascendancy of the ‘knowledge worker’ notwithstanding, the fundamental connection between education and employment is unraveling. In this climate, the purposes of education are constantly queried and scrutinized as its telos is redefined by criteria external to the practice of education: cost-effectiveness, value-for-money, and so on. I suggest that only be reclaiming a meaningful conception of adulthood can education be defended and only by so doing can individuals hope to understand the world around them.
