Color categories and color appearance

We examined categorical effects in color appearance in two tasks, which in part differed in the extent to which color naming was explicitly required for the response. In one, we measured the effects of color differences on perceptual grouping for hues that spanned the blue-green boundary, to test whether chromatic differences across the boundary were perceptually exaggerated. This task did not require overt judgments of the perceived colors, and the tendency to group showed only a weak and inconsistent categorical bias. In a second case, we analyzed results from two prior studies of hue scaling of chromatic stimuli (De Valois, De Valois, Switkes, & Mahon, 1997; Malkoc, Kay, & Webster, 2005), to test whether color appearance changed more rapidly around the blue-green boundary. In this task observers directly judge the perceived color of the stimuli and these judgments tended to show much stronger categorical effects. The differences between these tasks could arise either because different signals mediate color grouping and color appearance, or because linguistic categories might differentially intrude on the response to color and/or on the perception of color. Our results suggest that the interaction between language and color processing may be highly dependent on the specific task and cognitive demands and strategies of the observer, and also highlight pronounced individual differences in the tendency to exhibit categorical responses.     

System justification and the defense of committed relationship ideology

A consequential ideology in Western society is the uncontested belief that a committed relationship is the most important adult relationship and that almost all people want to marry or seriously couple (DePaulo & Morris, 2005). In the present article, we investigated the extent to which the system justification motive may contribute to the adoption of this ideology. In Studies 1 and 2, we examined whether a heightened motive to maintain the status quo would increase defense of committed relationship values. In Study 3, we examined the reverse association, that is, whether a threat to committed relationship ideology would also affect sociopolitical system endorsement. As past research has found that the justification of political systems depends upon how much these systems are perceived as controlling, in Study 4 we tested whether the defense of the system of committed relationships would also increase when framed as controlling. Results from Studies 1-4 were consistent with our hypotheses, but only for men. In Study 5, using cross-cultural data, we sought to replicate these findings correlationally and probe for a cause of the gender effect. Results from more than 33,000 respondents indicated a relationship (for men) between defense of the sociopolitical system and defense of marriage in countries where the traditional advantages of men over women were most threatened. In Studies 6 and 7, we investigated when this gender difference disappears. Results revealed that when we measured (Study 6) or manipulated (Study 7) personal relationship identity rather than relationship ideology, effects also emerge for women.     

The development of the Social Bullying Involvement Scales

This study reports findings of a newly developed measure of social bullying based on Underwood's [2003] framework of social aggression. The Social Bullying Involvement Scales (SBIS) consist of four scales measuring the extent to which children experience social victimization, engage in social bullying, witness social bullying, and intervene in social bullying. The sample consisted of 636 participants (311 females and 325 males, age range 11-16 years; 71% White). Confirmatory factor analysis supported a revised version of Underwood's framework for each of the four participant role scales. Internal consistencies for each scale ranged from .93 to .97. Results revealed that social victimization was related to an increase in anxiety, depressive, and externalizing behaviors. Social bullying was associated with an increase in general externalizing behaviors only. Social witnessing was moderately correlated with depression scores. Intervening in social bullying was not linked with psychological maladjustment or externalizing behaviors. The SBIS provides a comprehensive measure of social victimization, social bullying, social witnessing, and social intervening.     

The relationship between intelligence and multiple domains of religious belief: Evidence from a large adult US sample

High levels of religiosity have been linked to lower levels of intelligence in a number of recent studies. These results have generated both controversy and theoretical interest. Here in a large sample of US adults we address several issues that restricted the generalizability of these previous results. We measured six dimensions of religiosity (rather than just one or two), along with a multi-scale instrument to assess general intelligence. We also controlled for the influence of the personality trait openness on facets of religious belief and practice. The results indicated that lower intelligence is most strongly associated with higher levels of fundamentalism, but also modestly predicts central components of religiosity such as a sense of religious identification and private religious practice. Secondly, we found that a higher level of openness - often assumed to lead to lower religiosity - is weakly associated with reduced fundamentalism but with increased religious mindfulness, private religious practice, religious support, and spirituality. These new results provide a framework for understanding the links between reasoning and faith.     

Personality accounts for stable preferences and expectations across a range of simple games

Behaviour on even simple experimental games shows considerable individual differences, but previous attempts to link these preferences to stable personality traits have had mixed results. Here we address three limitations of earlier studies, namely: (1) uncertainties concerning the reliability of preferences; (2) use of personality instruments with limited cross-study comparability; and (3) confounds where more than one psychological motive can lead to a particular choice. Sixty-seven participants completed 12 distinct real-money games twice over a two-week interval along with 6 measures concerning their expectations about other players’ choices. Personality was measured using the full NEO-PI-R. Choices were highly stable across time (r = .84). Moreover, choices on the 12 games and 6 expectations reflected a single underlying dimension of “prosocial orientation”, measuring concern for the payoffs received by other players. Scores on the prosocial orientation dimension were related to personality, with openness, (low) neuroticism, and (low) extraversion retained as significant predictors.     

The Role of Parental Distress in Moderating the Influence of Child Neglect on Maladjustment

Despite pervasive evidence of the harmful impact of neglect on children’s adjustment, individual differences in adaptation persist. This study examines parental distress as a contextual factor that may moderate the relation between neglect and child adjustment, while considering the specificity of the relation between neglect and internalizing versus externalizing problems. In a sample of 66 children (33 with a documented child protective services history of neglect prior to age six), neglect predicted internalizing, and to a lesser extent externalizing, problems as rated by teachers at age seven. Parental distress moderated the relation between neglect and internalizing, but not externalizing, problems. Specifically, higher levels of neglect predicted more internalizing problems only among children of distressed parents. These findings indicate that parent-level variables are important to consider in evaluating the consequences of neglect, and point to the importance of considering contextual factors when identifying those children most at risk following neglect.
