Can memory requirements account for species' differences in invisible displacement tasks?

We tested the hypothesis that poor performance on the Piagetian invisible displacement task is related to increased memory requirements. Rhesus monkeys and orangutans received 3 types of problems (invisible, visible, and no transfer problems) each containing a number of steps equivalent to that of standard invisible displacements. If failure to solve invisible displacements was due to increased memory requirements, then the primates should perform at chance level on all 3 problems. However, rhesus monkeys solved visible and no transfer problems, but not invisible transfer problems. Half of the orangutans solved all 3 transfer problems, although their performance on invisible transfer problems was lower than that on the other problems. A subsequent cuing phase led to improved performance, and a few monkeys solved invisible transfer problems.     

The Cultural Factor in Lay Perception of Jealousy as a Motive for Wife Battery1

Cultural psychology is concerned with the comparative study of the way culture and psyche shape each other: This process is particularly well illustrated in the social construction of some feelings. Although sexual jealousy seems to be universal, people differ in the intensity of their reactions and in the type of stimuli perceived as threatening. Replicating previous research in Britain by Delgado and Bond (1993), a questionnaire research survey was conducted in Spain to determine if lay perception considers jealousy a justification for wife battery. The comparison of results shows striking differences: The harmdoer was seen as more guilty in Britain and the victim was seen as more guilty in Spain. Results demonstrate cultural differences in the perception of jealousy; when jealousy is a motive for assault, there are also cultural differences in judgments of responsibility. Emotions function differently in different cultures regarding perceived causes and justification for conduct.     

Imagery and the autonomic nervous system: some methodological issues.

The present paper is concerned with the role played by image content in the mediation of autonomic nervous system (ANS) arousal. The minimum methodological requirements of such studies are described including controls for imaging, image content, and expectancy effects. Studies meeting these requirements are then reviewed. It is concluded that image content can be a significant modifier of ANS arousal and that this property is not restricted to images containing affective, e.g., phobic, content. These conclusions have relevance to research into techniques such as biofeedback, Transcendental Meditation, and progressive relaxation, where imagery many have a profound influence but where it has received little direct empirical attentiol.     

Moderate Aerobic Exercise, T'ai Chi, and Social Problem-Solving Ability in Relation to Psychological Stress

This study evaluated the importance of exercise mode, social problem-solving ability, gender, and age in relation to anxiety and perceived daily hassles. Adult participants were classified as moderate aerobic exercisers, T'ai Chi exercisers, or sedentary via completion of a questionnaire. Social problem-solving ability, state and trait anxiety, and frequency and severity of daily hassles were measured. As predicted, scores indicating effective social problem-solving ability were associated with fewer reported severe daily hassles and with lower scores on state and trait anxiety. For state and trait anxiety, a main effect of exercise mode emerged after age and gender were controlled. A 3-way interaction involving age, gender, and exercise mode suggested that age and gender moderate the effects of exercise on anxiety, that is, the stress-reducing efficacy of different exercise modes may be dependent on a person's age and/or gender. Implications for theory, research, and practice are discussed.     

冲突与支持影响情侣依恋的文化差异

采用香港和美国的被试,运用亲密关系经历量表、冲突量表和社会支持量表,考察了冲突和支持对于情侣依恋影响的文化差异。结果发现,当以依恋焦虑为因变量时,冲突、支持和文化 × 冲突 × 支持都是显著的预测变量;当以依恋逃避为因变量时,仅文化和文化 × 支持是显著的预测变量。由此可见,文化影响冲突 × 支持与依恋焦虑的关系：在香港,情侣之间的冲突和支持各自对于依恋焦虑的作用在很大程度上相互抵消;在美国,情侣之间冲突的负面影响比支持的积极影响要强,冲突 × 支持越高,依恋焦虑越高。对于依恋逃避,文化差异仅调节支持与依恋逃避的关系：在香港,支持对依恋逃避的影响要比美国强。整个研究表明,对不同类型的情侣依恋,文化的调节作用不同。     

Elderly homicide in Chicago: a research note

There is a body of knowledge about elderly crime victims, but we know little about the characteristics of elderly perpetrators, especially of homicide. The few studies that have been published are based on small samples and are somewhat dated. In an examination of homicides committed in Chicago over a 31-year period, we compared cases involving perpetrators aged over 60 years (n = 443) with those involving younger perpetrators (n = 24,066). There were a number of significant differences. Elderly killers were more likely to be White and to commit suicide afterwards. Their victims were more likely to be spouses, females, and aged over 60 years. Inter-racial homicide was more common for younger offenders. The low number of homicides involving the elderly is explained by reference to routine activity theory.     

Information distortion in the evaluation of a single option

Extending previous work on biased predecisional processing, we investigate the distortion of information during the evaluation of a single option. A coherence-based account of the evaluation task suggests that individuals will form an initial assessment of favorability toward the option and then bias their evaluation of subsequent information to cohere with their initial disposition. Three experiments tested this hypothesis. Initial disposition was manipulated (Studies 1 and 3) or measured (Study 2), and attribute ratings were collected as indicators of information distortion. Results from all three experiments indicate that attribute evaluations were biased to favor initial dispositions. These findings provide evidence that information distortion is one cause of primacy effects in judgment and decision-making settings involving a single option.     

Gaming magazines and the drive for muscularity in preadolescent boys: a longitudinal examination

The development of a drive for muscularity among boys has been linked to various cultural influences, one of which is exposure to mass media depicting the muscular male body ideal. We sought to determine whether self-reported exposure to four ideal-body magazine genres (health/fitness, fashion, sports, and gaming) predicted an increased drive for muscularity 1 year later. A sample of 104 Black and 77 White preadolescent boys (mean age 8.77) participated in a 2-wave longitudinal panel study. Controlling Wave 1 grade, perceived thinness/adiposity, and drive for muscularity, exposure to video gaming magazines predicted a significant increase in Wave 2 drive for muscularity, but only for White boys. Discussion calls for the inclusion of video gaming magazine exposure measures in future research on print media and male body ideals, along with empirical exploration of racial themes in gaming magazines.     

The Increment of Social Axioms over Broad Personality Traits in the Prediction of Dyadic Adjustment: An Investigation Across Four Ethnic Groups

This study investigates the relationship between personality, social axioms, and dyadic adjustment. A sample of 420 participants (210 heterosexual couples), approximately evenly distributed between four ethnic backgrounds (Romanian, Hungarian, German, and Rroma), was investigated in a cross‐sectional approach with the Romanian versions of the Social Axioms Survey, the Dyadic Adjustment Scale, and the Revised NEO Personality Inventory. The analyses were based on the actor–partner interdependence model. The results showed that social axioms show incremental validity over personality traits in the prediction of dyadic adjustment, attesting to the usefulness of a worldview measure in predicting interpersonal outcomes over and above that provided by a measure of personality. Three of the five dimensions of social axioms were associated with dyadic adjustment, with either actor or partner effects. A few significant differences have been found between the various ethnic groups on effects of the social axioms on dyadic adjustment: The positive actor effect of reward for application is not visible for German men, the negative partner effect of social cynicism is not detectable for Rroma men, and the negative partner effect of social complexity is not visible for Rroma women.
