Extremes of self-esteem and narcissism and the experience and expression of anger and aggression

This study examined the level of self-esteem and narcissism as personality variables involved in the disposition to experience and express anger. Three hundred thirty-eight subjects were sampled across two higher education centres and one student teaching programme in the United Kingdom. It was reasoned that individuals with both high self-esteem and narcissism would report especially high tendencies to experience and express anger and aggression and that those with high self-esteem and low narcissism would report the lowest. These predictions were influenced by theories that emphasise the role of threats to high self-esteem in the production of aggression and violence. Results indicate that groups defined by their extreme scores on self-esteem and narcissism scales produced levels of anger expression in the predicted direction. The importance of considering extreme levels of self-esteem and narcissism (in conjunction with other factors) in an analysis of anger is discussed with reference to currently influential theories in the field.

Cognitive and Personality Characteristics of Masculinity and Femininity Predict Wayfinding Competence and Strategies of Men and Women

Bem (1974) reconceptualized masculinity and femininity as independent and orthogonal constructs that both men and women possess to varying degrees. This perspective was used as a starting point to investigate whether the contributions of gender-typed characteristics can help to account for commonly observed gender differences in wayfinding (the ability to identify one’s current location and successfully navigate to an unseen location in the environment) favoring men. We further divided gender-typed characteristics into cognitive and personality characteristics to assess their separate influence on wayfinding and explored whether gender-typed characteristics predicted self-reported use of masculine wayfinding strategies (i.e., orientation strategies) and self-reported wayfinding competence. Participants were 452 college women and men in a southern U.S. public university. They completed the Gender-Stereotypic Characteristics questionnaire (Diekman and Eagly 2000), a social comparison questionnaire (created by the authors), a wayfinding strategy questionnaire (Lawton 1994), and a wayfinding competence questionnaire (Hegarty et al. 2002). For both men and women, higher masculine cognitive characteristics significantly correlated with greater use of orientation wayfinding strategies typical of men. For men, both higher masculine and feminine cognitive characteristics predicted better overall wayfinding competence whereas for women, only higher masculine cognitive characteristics predicted better overall wayfinding competence. For both men and women, higher feminine personality characteristics predicted poorer wayfinding competence. These results demonstrated the importance of considering cognitive and personality characteristics of masculinity and femininity in explaining individual differences in wayfinding.     

Self-ratings of positive and negative affect and retrieval of positive and negative affect memories

Abstract

Based on analysis of self-ratings of mood, positive affect (PA) and negative affect (NA) have been proposed as basic, orthogonal mood dimensions (Watson & Tellegen, 1985). The present study asked subjects (N = 61) to not only provide self-ratings of PA and NA terms but also to retrieve personal memories associated with those terms. Self-rated PA was associated with latency to retrieve PA- but not NA-related memories; self-rated NA was associated with latency to retrieve NA- but not PA-related memories. Self-ratings of PA and NA were not significantly correlated, nor were retrieval latencies for PA and NA memories. Individual item correlations also revealed a strong direct relationship between self-ratings and retrieval latency. The dissociations involving a non-self report measure strengthen the distinction between PA and NA, and the individual item correlations are interpreted as showing that self-ratings of affect are based upon the ease of retrieval of personal memories.     

Personality and conditioning of tumescence and detumescence

Retrospective questionnaire surveys have associated extroversion with sexual hedonism and both introversion and neuroticism with sexual inhibition, guilt and fear. These findings have been related by Eysenck to his general theory of personality. In the present study. eight normally functioning adult males participated in eight laboratory sessions involving conditioning and deconditioning of sexual arousal. Direct relationships were found between magnitude of sexual conditioning and extroversion, and between magnitude of sexual deconditioning and introversion. The findings with respect to neuroticism were suggestive but nonsignificant. The findings are discussed in terms of Eysenck's (1967) general theory of personality and Gray's (1972) extension of that theory.

Face aftereffects suggest interdependent processing of expression and sex and of expression and race

Bruce and Young (1986) proposed that functionally different aspects of faces (e.g., sex, identity, and expression) are processed independently. Although interdependent processing of identity and expression and of identity and sex have been demonstrated previously, evidence for interdependent processing of sex and expression is equivocal. Using a visual adaptation paradigm, we show that expression aftereffects can be simultaneously induced in different directions along anger–fear continua for male and female faces (Experiment 1) and for East Asian and Black African faces (Experiment 2). These findings for sex- and race-contingent expression aftereffects suggest that processing of expression is interdependent with processing of sex and race and are therefore problematic for models of face perception that have emphasized independent processing of functionally different aspects of faces. By contrast, our findings are consistent with models of face processing that propose that invariant physical aspects of faces and changeable social cues can be processed interdependently.     

Perception and masking of wholes and parts

These exerpiments show that the effects of masking on reports of target lines depend on the context in which the target lines appear. Subjects viewed brief presentations of target lines either alone or in drawings of three-dimensional objects, and each target display was preceded and followed by one of several different mask stimuli. There were two main findings: (a) A mask containing a haphazard array of lines interfered more with single lines than it did with lines in objects. (b) A mask containing drawings of the object displays interfered more with lines in objects than did either of two control masks containing relatively flat, less coherent patterns. In a control condition, the object mask interfered slightly less with reports of single lines than either of the control masks did. The discussion considers how the effects obtained here bear on models of the processing of wholistic stimuli and their component parts.     

Selection and consolidation of objects and actions

Response selection bottleneck models attribute performance costs under dual-task conditions to the human inability to select more than one response at a time. Consistent with this claim Pashler (1991) found that carrying out a speeded manual choice reaction time (RT) task does not impair the unspeeded report of a cued visual target from a masked display. In contrast, Jolicoeur and DellAcqua (1999, Experiment 2) observed pronounced interference between a speeded manual choice RT task and the unspeeded report of a small number of visually presented letters, a finding they attributed to resource sharing between response selection and stimulus consolidation. We demonstrate that comparable costs are obtained with the same task combination used by Pashler (1991) if only task order is reversed—a manipulation that is likely to increase the necessity of consolidating the target stimulus into working memory. We also found that these costs are not diminished if the location of the target to be reported is cued in advance (reducing demands on spatial focusing) and that they do not vary with the number of target features to be reported. These findings support a consolidation account of costs in dual-task performance.     

Values and Beliefs of Vegetarians and Omnivores

Abstract

Following the claim by some anthropologists and sociologists that 1 symbolic meaning of meat is a preference for hierarchical domination (C. J. Adams, 1990; N. Fiddes, 1989; D. D. Heisley, 1990; J. Twigg, 1983), the authors compared the values and beliefs of vegetarians and omnivores in 2 studies conducted in New Zealand. They compared the full range of vegetarians and omnivores on right-wing authoritarianism, social dominance orientation, human values, and consumption values. The participants tending toward omnivorism differed from those leaning toward veganism and vegetarianism in 2 principal ways: The omnivores (a) were more likely to endorse hierarchical domination and (b) placed less importance on emotional states. Accordingly, the acceptance or rejection of meat co-varied with the acceptance or rejection of the values associated with meat; that finding suggests that individuals consume meat and embrace its symbolism in ways consistent with their self-definitions.

科学技术革命与流行病学思维的发展

人类认识自然界的思维方式千变万化,根据其历史发展的顺序,可分为四种基本思维方式。即:直观的和思辨的思维方式、实证的和逻辑的思维方式、概率的和统计的思维方式、开放的和非线性的思维方式[1]。这四种思维方式分别建立在不同的科学技术水平上。也就是说,其发展过程是随着科学技术的发展而形成的。纵观流行病学概念和思维的发展过程,也经历了上述的各个阶段。而且其思维方式每上升一个阶段都是由科技发展所决定的。由此可见,流行病学思维的发展与科技革命是息息相关的。1　古代病因概念———直观的经验的思维方式的产物古人通过长期的观…
