Of two minds: The interactive effect of construal level and identity on political polarization

Construal level theory posits that that when people are thinking abstractly (vs. concretely) they rely more on their core and consistent attitudes and values. However, past research has been mixed on whether abstract thinking causes liberals and conservatives to become more or less polarized. In the current research, we examine how identity salience moderates the effect of construal level on political polarization. Results from two studies suggest that identity salience (political vs. national) plays a key role in predicting how construal level affects attitude polarization. When people's political identity was made salient, liberals and conservatives were more polarized about political issues when thinking abstractly (vs. concretely). Conversely, when national identity was salient, liberals and conservatives were less polarized when in an abstract (vs. concrete) mindset. Broadly, this research highlights the importance identity salience has in understanding the role abstract (vs. concrete) thinking has on people's attitudes and values.     

Monocular and Binocular Vision in the Control of Goal-Directed Movement

In the present research the authors examined the time course of binocular integration in goal-directed aiming and grasping. With liquid-crystal goggles, the authors manipulated vision independently to the right and left eyes of 10 students during movement preparation and movement execution. Contrary to earlier findings reported in catching experiments (I. Olivier, D. J. Weeks, K. L. Ricker, J. Lyons, & D. Elliott, 1998), neither a temporal nor a spatial binocular advantage was obtained in 1 grasping and 2 aiming studies. That result suggests that, at least in some circumstances, monocular vision is sufficient for the precise control of limb movements. In a final aiming experiment involving 3-dimen- sional spatial variability and no trial-to-trial visual feedback about performance, binocular vision was associated with greater spatial accuracy. Binocular superiority appeared to be most pronounced when participants were unable to adjust their limb control strategy or procedure on the basis of terminal feedback about performance.     

Evaluating the effect of educational media exposure on aggression in early childhood

Preschool-aged children (M = 42.44 months-old, SD = 8.02) participated in a short-term longitudinal study investigating the effect of educational media exposure on social development (i.e., aggression and prosocial behavior) using multiple informants and methods. As predicted, educational media exposure significantly predicted increases in both observed and teacher reported relational aggression across time. Follow-up analyses showed that educational media exposure also significantly predicted increases in parent reported relational aggression across more than a two year period. Results replicate and extend prior research that has demonstrated links between educational media exposure and relational aggression, but not physical aggression, during early childhood.     

Gender Differences in Associations with Deviant Peer Groups: Examining Individual,Interactional, and Compositional Factors

Researchers have long known that boys are more likely to have deviant peers than are girls. Yet, little research has tried to explain why boys and girls differ in their decision to associate with deviant peers. With the salience of deviant peers well established as a robust predictor of delinquency, we address the question, are the predictors of association with deviant peers different for boys and girls? In our examination of family and community processes, individual effects, and peer group composition factors, we find that the predictors of association with deviant peers differ by gender. In addition, our findings suggest gender divergences in the causes of both deviant peer association and deviant peer pressure. We discuss the implications of our research for both theoretical development and appropriate model estimation.     

Mammograms and the management of existential discomfort: Threats associated with the physicality of the body and neuroticism

The current research employs ideas from terror management theory to investigate why mammograms may be psychologically problematic. This perspective suggests that individuals, particularly those high in neuroticism, are threatened by that which reminds them of their physical and mortal nature. In Study 1, a laboratory experiment demonstrated that when concerns about mortality were primed, reminders of one's physical nature (i.e. creatureliness) led women who were high in neuroticism to report reduced willingness to imagine undergoing a mammogram. In Study 2, a field experiment among women receiving a mammogram showed that priming creatureliness increased perceptions of discomfort with the procedure for women high in neuroticism. Theoretical and practical implications are discussed.     

A survey of smoking status and cancer risk perceptions among participants attending a hospital-based head and neck screening program

Abstract

Screening for head and neck cancer is underutilized. Given that lack of knowledge of the risk factors may partially account for screening underutilization. we surveyed subjective risk and knowledge of risk factors for head and neck cancer among 124 individuals who attended a free. hospital-based head and neck cancer screening. Few participants were current smokers. Most attendees perceived their risk as similar to others of their age and sex. Personal health habits comprised almost all of the risk-decreasing factors, yet less than half of the risk-increasing factors. generated. Personal habits were less frequently endorsed than factors such as pollution and heredity. Those who mentioned a risk behavior, or a family cancer history, reported higher subjective risk. Those who mentioned a personal health habit reported lower subjective risk. Results highlight needed efforts to increase screening among high-risk individuals through targeted education messages.

Word learning is a lifelong activity constrained by cognitive biases that people possess at particular points in development. Age of acquisition (AoA) is a psycholinguistic variable that may prove useful toward gauging the relative weighting of different phonological, semantic, and morphological factors at different phases of language acquisition and development. Our aim here was to evaluate AoA as a statistical tool for taking “snapshots” of cognitive development. We examined a large corpus of English nouns (n = 1,381) with AoA as the outcome variable in three separate multivariate regressions, encompassing different age ranges (early–middle–late). Predictors included perceptual (e.g., imagery), phonological (e.g., phonological neighborhood density), and lexical (e.g., word length) factors. Different combinations of predictors accounted for significant proportions of the variance for different AoA ranges (i.e., early–middle–late). For example, imageability and frequency are stronger predictors of early relative to late word learning. These corpus analyses support a hybrid model of word learning in which multiple perceptual and linguistic factors are differentially weighted over time. This statistical approach may provide independent corroboration of and motivation for experimental studies in language learning and cognitive development.     

Balance and dyslexia: An investigation of adults’ abilities

Balance ability in dyslexia is an issue of considerable theoretical and applied significance, but the literature currently lacks consensus. This study applied objective measures to established balance tasks. 17 dyslexic adults and 20 controls matched for age and IQ undertook the heel-to-toe balance test for 1 minute. Further “dual task” tests were also undertaken in which the subject had to balance while undertaking secondary cognitive tasks (counting, slow choice reaction, fast choice reaction). Two factor analyses of variance revealed significant between-group balance differences in the dual task conditions. 24–82% of the dyslexic group showed balance impairment, depending on the criterion chosen. At the group level, the results are directly consistent with the Nicolson and Fawcett (1990) automatisation deficit hypothesis, but the considerable within-group heterogeneity deserves further investigation.
