组织成员地位的形成及影响机制

组织成员地位通常是指组织内个体受组织其他成员尊重和钦佩的程度,是近些年备受关注的一个心理学构念。虽然组织成员地位与权力、阶层、面子、基于组织的自尊等概念具有一定的关联性,但它们之间存在着明显的界限。组织成员地位主要受到外在显性因素(形体特征、人口统计特征)、内在心理因素(人格、认知、情绪、行为)以及神经生理因素(睾酮激素、皮质醇激素)的影响,并能够对组织成员的认知、情绪、行为和绩效产生显著的影响。未来研究应当进一步区分组织成员地位的维度,探索组织成员地位的生物学基础和文化差异,关注组织成员地位的动态演化及其后果,并检验团队和组织层面地位分布的作用机制。     

When the cat’s away,some mice will play: A basic trait account of dishonest behavior

In line with every-day observation, research has established substantial individual differences in ethical behavior, especially dishonesty and cheating. However, these individual differences have remained mostly unexplained, especially in terms of traits as specified in models of basic personality structure. Theoretically, a prime candidate to account for these differences is the Honesty–Humility factor proposed as the sixth basic personality dimension within the HEXACO Model of Personality. Despite clear theoretical links, corresponding behavioral evidence is scarce and limited due to methodological caveats. In a series of six behavioral experiments we thus bridge the gap between behavioral ethics and personality research – critically testing whether individual differences in dishonest behavior can be accounted for by basic traits in general, and Honesty–Humility in particular. We implement different cheating paradigms, tasks, incentive structures, samples, and sets of covariates to evaluate the robustness and generality of results. Overall, variance in dishonest behavior was indeed accounted for by Honesty–Humility which was the only consistent predictor of cheating across the various experimental setups and beyond relevant covariates including other personality factors. The results thus corroborate that individual differences in ethical behavior can be accommodated by comprehensive models of personality structure in general and the Honesty–Humility factor in particular.     

Individual differences in impulsive choice and timing in rats

Individual differences in impulsive choice behavior have been linked to a variety of behavioral problems including substance abuse, smoking, gambling, and poor financial decision-making. Given the potential importance of individual differences in impulsive choice as a predictor of behavioral problems, the present study sought to measure the extent of individual differences in a normal sample of hooded Lister rats. Three experiments utilized variations of a delay discounting task to measure the degree of variation in impulsive choice behavior across individual rats. The individual differences accounted for 22-55% of the variance in choice behavior across the three experiments. In Experiments 2 and 3, the individual differences were still apparent when behavior was measured across multiple choice points. Large individual differences in the rate of responding, and modest individual differences in timing of responding were also observed during occasional peak trials. The individual differences in timing and rate, however, did not correlate consistently with individual differences in choice behavior. This suggests that a variety of factors may affect choice behavior, response rate, and response timing.     

Task-Intrinsic and Social-Extrinsic Sources of Arousal for Motives Assessed in Fantasy and Self-Report

ABSTRACT A review of the literature on individual differences in motive dispositions points toward the importance of distinguishing between motives as assessed in fantasy and self-report. We proposed that these two modes of assessment have identified independent motivational systems that influence behavior in different ways. Two experiments were designed to show that the two kinds of motives are unrelated to one another and are aroused by different factors in a performance situation. It was hypothesized that motives as assessed from fantasy (seen as implicit needs) are primarily aroused by factors intrinsic to the process of performing an activity, whereas motives obtained through self-report inventories (seen as self-attributed needs) are aroused by social factors that are extrinsic to the process of performing an activity (e.g., the way in which a task is presented by an experimenter). In the first experiment, performance on a memory task was shown to depend on the interaction of subjects' self-reported motive for achievement with achievement-arousing instructions, whereas performance on a word-finding puzzle depended on the interaction of subjects' fantasy need for achievement with the puzzle's level of intrinsic challenge. A second experiment generalized these findings to the power domain.     

Nature over nurture: temperament, personality, and life span development

Temperaments are often regarded as biologically based psychological tendencies with intrinsic paths of development. It is argued that this definition applies to the personality traits of the five-factor model. Evidence for the endogenous nature of traits is summarized from studies of behavior genetics, parent-child relations, personality structure, animal personality, and the longitudinal stability of individual differences. New evidence for intrinsic maturation is offered from analyses of NEO Five-Factor Inventory scores for men and women age 14 and over in German, British, Spanish, Czech, and Turkish samples (N = 5,085). These data support strong conceptual links to child temperament despite modest empirical associations. The intrinsic maturation of personality is complemented by the culturally conditioned development of characteristic adaptations that express personality; interventions in human development are best addressed to these.     

Psychological and neurological predictors of abusive supervision

Although the negative effects of abusive supervision are well documented, less is known about the individual differences that drive supervisors to be abusive. We use a self‐control perspective to understand the unique roles of both psychological and neurological characteristics of supervisors in the prediction of abusive behavior. Specifically, we find a positive relationship between narcissism and abusive supervision, whereas political skill and intrinsic neurological connectivity in executive control regions of the brain negatively relate to abusive supervision. Our results further show that the relationship between narcissism and abusive supervision diminishes for those who are strong in terms of political skill. In addition, neurological executive control moderates the relationship between political skill and abusive behavior. When connectivity in executive control regions of the brain is lower, political skill becomes a more important factor in reducing the display of abusive behavior. Overall, we demonstrate how combinations of characteristics (both psychological and neurological) can provide a more in‐depth understanding of the emergence of abusive supervision.

Causality orientations moderate the undermining effect of rewards on intrinsic motivation

The present study tested the hypothesis that individual differences in autonomy or control causality orientation would moderate the undermining effect of rewards on intrinsic motivation. Equal numbers of autonomy- and control-orientated participants provided solutions to an interesting puzzle under reward or no reward conditions. Participants were then required to provide further solutions to the puzzle in a free-choice period. The time spent in solving the puzzle during the free-choice period constituted the dependent measure of intrinsic motivation. Results revealed a significant interaction effect of causality orientations and reward condition on intrinsic motivation. Control-oriented participants assigned to the reward condition exhibited significantly lower levels of intrinsic motivation compared to those assigned to the no reward condition. In contrast, there was no significant difference in intrinsic motivation levels across the reward conditions for autonomy-oriented individuals. Findings indicate that an autonomy-oriented causality orientation offered a degree of ‘protection’ from the undermining effect of rewards on intrinsic motivation. This is in keeping with self-determination theory in terms of the interactive effects of environmental events and interpersonal factors on intrinsic motivation.     

Twins and the study of rater (dis)agreement

Genetically informative data can be used to address fundamental questions concerning the measurement of behavior in children. The authors illustrate this with longitudinal multiple-rater data on internalizing problems in twins. Valid information on the behavior of a child is obtained for behavior that multiple raters agree upon and for rater-specific perception of the child's behavior. Rater-disagreement variance varsigma2(rd) accounted for 35% of the individual differences in internalizing behavior. Up to 17% of this varsigma2(rd) was accounted for by rater-specific additive genetic variance varsigma2(Au). Thus, the disagreement should not be considered only to be bias/error but also as representing the unique feature of the relationships between that parent and the child. The longitudinal extension of this model helps to make a distinction between measurement error and the raters' unique perception of the child's behavior. For internalizing behavior, the results show large stability across time, which is accounted for by common additive genetic and common shared environmental factors. Rater-specific shared environmental factors show substantial influence on stability. This could mean that rater bias may be persistent and affect longitudinal studies.     

Intrinsic motivations and the non-profit health sector: Evidence from Ethiopia

Economists have traditionally assumed that individual behavior is motivated exclusively by extrinsic incentives. Social psychologists, in contrast, stress that intrinsic motivations are also important. In recent work, economic theorists have started to build psychological factors, like intrinsic motivations, into their models. Besley and Ghatak (2005) propose that individuals are differently motivated in that they have different “missions”, and their selection into sectors or organizations with matching missions enhances organizational efficiency. We test Besley and Ghatak’s model using data from a unique cohort study. We generated two proxies for intrinsic motivations: a survey-based measure of the health professionals philanthropic motivations and an experimental measure of their pro-social motivations. We find that both proxies predict health professionals’ decision to work in the non-profit sector. We also find that philanthropic health workers employed in the non-profit sector earn lower wages than their colleagues.

Observations on the behavior of gibbons (Hylobates leucogenys, H. gabriellae, and H. lar) in the presence of mirrors

Three captive gibbons (Hylobates leucogenys, H. gabriellae, and H. lar) were videotaped in the course of longitudinal exposure to mirrors introduced into their familiar cage or island housing situation. The gibbons, which differed in age, sex, species, and rearing condition, exhibited great individual differences in their behavioral reactions to mirrors, spanning from a minimal reaction dominated by social responses to a dramatic sequence of progressive behavioral change that featured a variety of contingency testing behaviors and included mirror-mediated, self-directed behavior. Additional information on the mirror competence of gibbons was provided by modified mark tests and a hidden object task. The results are discussed in relation to current criteria for self-recognition in primates and factors involved in individual and species differences in reactions to mirror exposure.     

Individual differences and cross-situational consistency of dyadic social behavior

A new theoretical analysis of individual differences and cross-situational consistency of behavior is proposed. The authors hypothesized that the social behavior of mice (Mus musculus) is determined by individual differences among animals in behavior emitted (i.e., actor effects), in behavior elicited from social partners (partner effects), and by unique responses of one animal to another (relationship effects). Each effect represents a distinct facet of individual differences with different psychological meaning; likewise, the cross-situational consistency of each effect has a distinct psychological meaning. Individual differences in behavior emitted were observed, and these actor effects were consistent longitudinally. Individual differences in behavior elicited from social partners were observed, and these partner effects were also consistent longitudinally. Unique responses to specific social partners also determined behavior but were inconsistent longitudinally. The theoretical importance of reconceptualizing the concepts of individual differences and cross-situational consistency in behavior is discussed. ((c) 2005 APA, all rights reserved).     

Curious eyes: individual differences in personality predict eye movement behavior in scene-viewing

Visual exploration is driven by two main factors - the stimuli in our environment, and our own individual interests and intentions. Research investigating these two aspects of attentional guidance has focused almost exclusively on factors common across individuals. The present study took a different tack, and examined the role played by individual differences in personality. Our findings reveal that trait curiosity is a robust and reliable predictor of an individual's eye movement behavior in scene-viewing. These findings demonstrate that who a person is relates to how they move their eyes.     

Sexual Strategies Theory: Built for the Short Term or the Long Term?

The evolutionary paradigm has provided psychology with a different perspective on human behavior, and with beneficial results. Sexual Strategies Theory (SST; Buss and Schmitt 1993) has been the primary evolutionary theory for studying human sexual behavior. A review of some SST-related research suggests that some of the paradigm??s anticipated female-male differences are supported. However, closer examination of this research also reveals substantial female-male similarities in sexual behavior, inconsistent or unclear definitions of several important SST concepts, and the functional omission of several important topics from the SST research agenda. Further, male-female differences in sexuality may be driven by a subset of males. Directions for future research are suggested, including greater attention to individual and contextual factors.     

Sexual behavior in young adulthood: a population-based twin study.

OBJECTIVE: With behavior genetic analyses of data from young adult twins, we evaluated theoretical perspectives that differentially emphasize biological dispositions, social/cultural factors, or universal pathways to explain individual differences in sexual behaviors. DESIGN: We fit biometric sex limitation models to three aspects of sexual behavior reported by 4,925 Finnish twins ages 23-27. MAIN OUTCOME MEASURE: From a postal questionnaire, we obtained self-report information on initiation/abstinence of sexual intercourse, onset age, and number of sexual partners. RESULTS: Genetic and non-shared environmental influences were significant for all three measures. There were trends for common environmental influences on initiation and, in females, age at first intercourse. Some differential effects in males and females were found. Results comparing onset age and number of partners among experienced twins from pairs concordant and discordant for initiation found genetic and environmental influences on initiation/abstinence overlapped those found for the other aspects of sexual behavior. CONCLUSIONS: These results document genetic variation in individual differences in sexual behavior of young adults. Incorporating genetic dispositions into integrated models of sexual behavior will facilitate more effective health promotion and risk taking intervention.     

Sexual behavior of Colombian high school students

This paper presents the results of a survey on the sexual behavior of Colombian high school students. It documents significant gender differences in the sexual behavior of Colombian adolescents as compared with the more egalitarian sexual behavior of their American and European counterparts. The study indicates that prostitutes are playing a decreasing role in the sexual lives of Colombian males as a result of a trend toward premarital coital permissiveness among Colombian females. The findings also support previous studies which indicate that there are intrinsic gender differences in the intensity and frequency of sexual desire.     

Genetically influenced change in sensation seeking drives the rise of delinquent behavior during adolescence

Sensation seeking is associated with an increased propensity for delinquency, and emerging research on personality change suggests that mean levels of sensation seeking increase substantially from childhood to adolescence. The current study tested whether individual differences in the rate of change of sensation seeking predicted within-person change in delinquent behavior and whether genetically influenced differences in rate of personality change accounted for this association. Sensation seeking and delinquent behavior were assessed biennially between ages 10-11 and 16-17 in a nationally representative sample of 7675 youths from the National Longitudinal Study of Youth: Children and Young Adults (CNLSY). Analyses using latent growth curve modeling found that within-person change in sensation seeking was significantly and positively correlated with within-person change in delinquency from childhood to adolescence. Furthermore, behavioral genetic analyses of a subset of 2562 sibling pairs indicated that there were substantial genetic influences on both initial levels of sensation seeking and change in sensation seeking during early adolescence, with over 80% of individual differences in change due to genetic factors. Finally, these genetically driven increases in sensation seeking were most important for predicting increases in delinquency, whereas environmental paths between sensation seeking and delinquency were not significant. These results suggest that developmental changes in delinquent behaviors during adolescence are driven by a genetically governed process of personality change.
