Imagery ability and the identification of hands: A chronometric analysis

In a replication of Cooper and Shepard's (1975) study of hand recognition, it was found that individual differences in imagery ability had a significant influence on reaction times to such stimuli (Experiment 1). However, it was found (Experiment 2) that individual difference effects were only seen if prior instructions to use imagery were given to the subjects.     

Repeated testing does not confound cognitive performance in the Western Australian magpie (Cracticus tibicen dorsalis)

The Criterion Validity of Broad Factor Scales versus Specific Facet Scales

We compared the validities of two Big Five personality factor scales with those of two lower-level facet scales that constituted each factor scale, with respect to self-report behavior criteria. Results demonstrated that the factor scales yielded significantly and substantially lower validities than did their constituent facet scales. These findings support our claim that separate scale scores should be reported routinely for the individual personality facets that define a broad factor, particularly when those facets do not correlate highly and when criteria of interest relate substantively to certain facets within the factor scale but not to others.     

Profiling the "pro-environmental individual": a personality perspective

There is considerable scientific interest in the psychological correlates of pro‐environmental behaviors. Much research has focused on demographic and social‐psychological characteristics of individuals who consistently perform such actions. Here, we report the results of 2 studies in which we explored relations between broad personality traits and pro‐environmental actions. Using a wide variety of behavior and personality measures, we consistently found moderate positive relations between Openness to Experience and pro‐environmental activities in both a community sample (Study 1: N = 778) and an undergraduate student sample (Study 2: N = 115). In Study 2, we showed that the effect of Openness on pro‐environmental behaviors was fully mediated by individuals’ environmental attitudes and connection to nature. Our findings suggest that high levels of aesthetic appreciation, creativity, and inquisitiveness, but not personality traits associated with altruism, may have motivated the performance of pro‐environmental actions among our respondents. Implications for intervention development are discussed.     

Role Ethics or Ethics of Role-Play? A Comparative Critical Analysis of the Ethics of Confucianism and the Bhagavad Gītā

Both Confucianism and the Bhagavad Gītā emphasize the moral authority of social roles. But how deep does the likeness between these ethical philosophies run? In this essay I focus upon two significant points of comparison between the role-based ethics of Confucianism and the Gītā: (1) the interrelation between formalized social roles and family feeling, and (2) the religious dimension of moral action. How is it that Confucians ground their social roles in family feeling, while the Gītā emphasizes rupture between role and sentiment? Furthermore, are we to understand Confucianism as presenting a social philosophy that eschews religious concerns, whereas the Gītā denies the moral significance of family feeling in lieu of obtaining soteriological freedom? Examining the aesthetic and religious dimensions of the ethics of Confucianism and the Gītā clarifies a key distinction that both views implicitly make, albeit for divergent reasons: the difference between living one’s roles and playing one’s roles.     

On the prediction of academic performance with personality traits: A replication study

We describe a large sample study (N = 652) that had two purposes. The first was to replicate a previous study (Paunonen & Ashton, 2001a, Journal of Research in Personality) in which we showed that lower-level personality trait measures related to achievement motivation predict the academic success of university students. The second purpose was to test our earlier conclusion that such lower-level traits are frequently superior to broader personality factors for accuracy in prediction. Both purposes were met in this study, providing more evidence for our general claim that aggregating narrow personality trait measures into broad factor measures can sometimes have negative consequences regarding the prediction and understanding of important outcomes, including academic performance.     

Relational aggression in marriage

Drawing from developmental theories of relational aggression, this article reports on a study designed to identify if spouses use relationally aggressive tactics when dealing with conflict in their marriage and the association of these behaviors with marital outcomes. Using a sample of 336 married couples (672 spouses), results revealed that the majority of couples reported that relationally aggressive behaviors, such as social sabotage and love withdrawal, were a part of their marital dynamics, at least to some degree. Gender comparisons of partner reports of their spouse's behavior revealed that wives were significantly more likely to be relationally aggressive than husbands. Structural equation modeling demonstrated that relational aggression is associated with lower levels of marital quality and greater marital instability for both husbands and wives. Implications are drawn for the use of relational aggression theory in the future study of couple conflict and marital aggression Aggr. Behav. 36:315–329, 2010. © 2010 Wiley‐Liss, Inc.     

Mirror neurons, the representation of word meaning, and the foot of the third left frontal convolution

Previous neuroimaging research has attempted to demonstrate a preferential involvement of the human mirror neuron system (MNS) in the comprehension of effector-related action word (verb) meanings. These studies have assumed that Broca's area (or Brodmann's area 44) is the homologue of a monkey premotor area (F5) containing mouth and hand mirror neurons, and that action word meanings are shared with the mirror system due to a proposed link between speech and gestural communication. In an fMRI experiment, we investigated whether Broca's area shows mirror activity solely for effectors implicated in the MNS. Next, we examined the responses of empirically determined mirror areas during a language perception task comprising effector-specific action words, unrelated words and nonwords. We found overlapping activity for observation and execution of actions with all effectors studied, i.e., including the foot, despite there being no evidence of foot mirror neurons in the monkey or human brain. These "mirror" areas showed equivalent responses for action words, unrelated words and nonwords, with all of these stimuli showing increased responses relative to visual character strings. Our results support alternative explanations attributing mirror activity in Broca's area to covert verbalisation or hierarchical linearisation, and provide no evidence that the MNS makes a preferential contribution to comprehending action word meanings.
