Rodney King and O. J. Revisited: The Impact of Race and Defendant Empathy Induction on Judicial Decisions

White university students participated in a study to investigate the impact of defendant race and empathetic induction on a subsequent juror decision-making task. Participants read a passage involving a Black or a White defendant in a criminal case. They were subsequently induced to feel no empathy, low empathy, or high empathy for the defendant. When compared to participants in the low- and control empathy conditions, those in the high-empathy condition reported greater target empathy, made attributions that were more situational, and assigned more lenient punishments. The results also indicate that group membership can moderate the impact of empathetic induction. When compared to the participants in the Black defendant condition, those in the White defendant condition reported greater target empathy, made attributions that were more situational, and assigned more lenient punishments. Implications for both empathy and judicial decision-making research are discussed.     

A comparative analysis of serial ordering in ring-tailed lemurs (Lemur catta)

Research over the last 25 years has demonstrated that animals are able to organize sequences in memory and retrieve ordered sequences without language. Qualitative differences have been found between the serial organization of behavior in pigeons and monkeys. Here the authors test serial ordering abilities in ring-tailed lemurs, a strepsirrhine primate whose ancestral lineage diverged from that of monkeys, apes, and humans approximately 63 million years ago. Lemurs' accuracy and response times were similar to monkeys, thus suggesting that they may share mechanisms for serial organization that dates to a common primate ancestor.     

Judgment of angle size: An experimental appraisal

Previous work on the estimation of angle size suggested that three factors play a significant part in the forming of an accurate estimation: the size of the angle, its orientation, and the mode in which the response is made. An examination of the judgment by 60 Ss of 12 angles under varied conditions of orientation, response mode, and cue was carried out with the result that the importance of size and orientation was confirmed. Despite an overall significant difference in estimation between response modes, there was no indication of a consistent effect across angles for the different modes. Predictions on the influence of orientation made by Fisher and Beery were tested, and while the former investigator was adequately supported, the latter was held to have reported results on a limited sample of angles which do not generalize to the wider range of angles used in the present study.     

Monkeys match and tally quantities across senses

We report here that monkeys can actively match the number of sounds they hear to the number of shapes they see and present the first evidence that monkeys sum over sounds and sights. In Experiment 1, two monkeys were trained to choose a simultaneous array of 1-9 squares that numerically matched a sample sequence of shapes or sounds. Monkeys numerically matched across (audio-visual) and within (visual-visual) modalities with equal accuracy and transferred to novel numerical values. In Experiment 2, monkeys presented with sample sequences of randomly ordered shapes or tones were able to choose an array of 2-9 squares that was the numerical sum of the shapes and sounds in the sample sequence. In both experiments, accuracy and reaction time depended on the ratio between the correct numerical match and incorrect choice. These findings suggest monkeys and humans share an abstract numerical code that can be divorced from the modality in which stimuli are first experienced.     

Transcendence and the Moral Self: Identity Integration, Religion, and Moral Life

Although moral reasoning is able to account for some of the variability in moral behavior, much remains unexplained. Recently, a number of components of personality have been proposed as bridging the gap between moral reasoning and moral behavior. The present study investigates the role that identity integration (the extent to which one's moral values have become integrated into identity) and religious orientation (one's motivation for engaging in religious practice) play in moral functioning. A sample of 60 undergraduates was assessed on identity integration, religious orientation, moral reasoning, and self-reported altruism. We found positive correlations among moral reasoning, identity integration, intrinsic religious orientation, and self-reported altruism. A hierarchical regression analysis, however, revealed moral reasoning to be the only significant predictor of self-reported altruistic behavior. We discuss the relationship between moral reasoning and identity integration and the extent to which the intrinsic religious orientation scale may be a measure of identity integration in the religious domain.
