Despite its avowed goal of understanding individual behavior, the field of behavior analysis has largely ignored the determinants of consistent differences in level of performance among individuals. The present article discusses major findings in the study of individual differences in intelligence from the conceptual framework of a functional analysis of behavior. In addition to general intelligence, we discuss three other major aspects of behavior in which individuals differ: speed of processing, working memory, and the learning of three-term contingencies. Despite recent progress in our understanding of the relations among these aspects of behavior, numerous issues remain unresolved. Researchers need to determine which learning tasks predict individual differences in intelligence and which do not, and then identify the specific characteristics of these tasks that make such prediction possible. 相似文献

The two fundamental dimensions assumed to underlie emotional experience—pleasure and arousal—are considered to be independent across individuals. We present evidence from an experience sampling study demonstrating that this independence does not necessarily hold when considering the affective experiences of a single individual. Participants (N = 80) reported how they were feeling in terms of pleasure and arousal nine times a day for seven days. The data showed that, although on average pleasure and arousal were independent, within-person pleasure–arousal associations substantially varied and ranged from strongly positive to strongly negative. This finding demonstrates that pleasant/unpleasant feelings usually co-occur with high arousal for some (reflecting joy/stress), but with low arousal for others (reflecting relaxation/sadness) and that persons differ in whether arousal is usually pleasant or unpleasant. These differences were found to be related to dispositional reward responsiveness, with high reward responsive individuals being characterized by a positive relation between pleasure and arousal and vice versa. 相似文献

The purpose of this study was to investigate consumption patterns of gay‐oriented sexually explicit media (SEM) among men who have sex with men (MSM) in Norway, with a particular emphasis on a possible relationship between gay SEM consumption and HIV risk behavior. Participants included 529 MSM living in Norway recruited online to complete a SEM consumption and sexual risk survey. Of the 507 participants who responded to the all items measuring exposure to SEM, 19% reported unprotected anal intercourse with a casual partner (UAI) in last 90 days, and 14% reported having had sero‐discordant UAI. Among those with UAI experience, 23% reported receptive anal intercourse (R‐UAI) and 37% reported insertive anal intercourse (I‐UAI). SEM consumption was found to be significantly associated with sexual risk behaviors. Participants with increased consumption of bareback SEM reported higher odds of UAI and I‐UAI after adjusting for other factors using multivariable statistics. MSM who started using SEM at a later age reported lower odds of UAI and I‐UAI than MSM who started earlier. Future research should aim at understanding how MSM develop and maintain SEM preferences and the relationship between developmental and maintenance factors and HIV sexual risk behavior. 相似文献

In experimental game-theoretic research, to the extent that sex has been considered at all, the approach has been to focus on the individual level of analysis. This paper reports the results of experiments designed to focus on sex/gender and to expand the level of analysis to include the institutional level. An asymmetric game was designed such that players in the male and female institutional locations had 3 and 2 alternatives, respectively. Players earned the institutional locations based on a test, so that top and bottom scorers respectively merited the 3- and 2-alternatives locations. Game-theoretic understandings of sex-of-player were compared to the expectations states theory concept of sex status; that is, men expect and are expected to perform more competently than women. Results indicated that top-scorer men and women behave similarly; bottom-scorer men resist their low merit status (behaving the most rationally of all player groups); bottom-scorer women accept their low merit status (behaving the most irrationally of all player groups). Whereas game theory cannot provide a coherent understanding of these findings, the concept of sex status helps to interpret the behavior of all four player groups and shows how judgments about rationality and irrationality depend critically on the interpretive framework used. 相似文献

This study examines the predictors of two measures of anxiety, viz. free-floating anxiety and somatic anxiety (Crown & Crisp, 1979), in (a) male and female money market dealers, and (b) money market dealers working in organizations of differing national ownership, in the City of London. Previous research suggests that differences in anxiety may be sex-based, and also that takeovers and mergers, particularly by foreign-based organizations, result in particular anxieties. Following interviews, 225 questionnaires were completed by dealers in the City of London. Analysis of questionnaire data indicates that the sources of anxiety are different for the sexes; and that the sources of anxiety are different for dealers working in U.K.-owned and U.S.-owned financial institutions. The implications of the results and suggestions for future research are discussed. 相似文献

Age,Emotion Regulation,and Affect in Adulthood: The Mediating Role of Cognitive Reappraisal 下载免费PDF全文

Evidence indicates that older adults experience high levels of emotional well‐being. However, little is known empirically about the underlying mechanism of this state. The purpose of the present study was to investigate whether emotion regulation mediates the link between age and affect in adulthood. The sample consisted of 516 Japanese participants aged 30 (±1), 50 (±1), and 70 (±1) years, who were registered with an Internet survey company. Cognitive reappraisal and expressive suppression were measured as emotion regulation strategies. Positive and negative affect were assessed. Older participants reported lower negative affect than younger participants, while positive affect was not correlated with age. Cognitive reappraisal partially mediated the relationship between age and affect, whereas expressive suppression did not. The results suggested that age‐related increase in cognitive reappraisal could contribute to improvements in affect, but that another adaptive form of emotion regulation may mediate the relationship between age and affect. Our study thus indicates that developments in emotion regulation could explain the mechanism of stable everyday affect throughout adulthood, and that researchers should further explore another form of adaptive emotion regulation. 相似文献

Disordered eating habits such as binge-eating, purging, and extreme diet restriction have been linked to a variety of deficits in emotion regulation. Two such aspects of emotion regulation are alexithymia and emotional expressivity, although much of the research is limited to females. This study examines associations between these aspects of emotion regulation and symptoms of bulimia nervosa (BN) in men and women. Participants were 201 female and male undergraduates who completed self-report measures of emotion regulation and BN symptoms. Consistent with prior research, results indicate that alexithymia predicted BN symptoms in females, but not in the presence of emotional expressivity, which proved to be the only unique predictor of BN symptoms. In the male sample, alexithymia predicted BN symptoms over and above emotional expressivity. These findings suggest that BN symptoms in males may partly be explained by one facet of emotion regulation, but they also highlight important gender differences in disordered eating. Future research should further examine the role of emotion regulation in eating pathology in males. 相似文献

We used census data on the civilian non-institutional adult population to analyze trends in labor force participation by race/ethnicity and sex in U.S. occupations from 1970 to 2010 in decennial periods. We examined these data for the main effects and interactions of race/ethnicity and sex across the total labor market and within 35 detailed occupations. Results from a log-linear analysis revealed that, as a whole (across race/ethnicity), more women participated in the labor force from 1970 to 2010. The proportions of working racial/ethnic minorities to both the population and the people in the labor force increased across all decades except for Black men. Although White (Caucasian) men continuously comprised the largest racial/ethnic–sex group working across five decades in absolute numbers, their percentage of the total working population declined from 1970 (54%) to 2010 (37%). In our analyses of 35 occupations, significant sex differences within racial/ethnic groups emerged. Overall, with some exceptions, Asian men and women and White women were more likely to be absorbed into occupations typically associated with professional status whereas Black, Hispanic, and American Indian men and women were more likely to be absorbed into occupations typically associated with low skill, low wages, and low status. Implications for the role of psychologists in future research, practice, and policy are discussed. 相似文献

More than Just the Breadwinner: The Effects of Fathers' Parenting Stress on Children's Language and Cognitive Development 下载免费PDF全文
Despite numerous studies on parenting stress suggesting negative influences on parent–child interactions and children's development, the majority of these studies focus on mothers' parenting stress with little or no acknowledgement of fathers. Using data from the National Early Head Start Research and Evaluation Project, this study examined (i) the effects of fathers' parenting stress during toddlerhood on children's language and cognitive outcomes when children are 3 years old (ii) whether the effects of fathers' parenting stress on children's language and cognitive development vary by child gender? Results from mixed linear models showed fathers' parenting stress predicted children's lower cognitive scores, but there were no gender differences in the effects of fathers' parenting stress on children's cognitive outcomes. In the language domain, boys, not girls, were found to be more susceptible to the effects of fathers' parenting stress. These findings indicated that fathers, in addition to mothers, should be included in early parenting research and interventions. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

Men's and women's personalities appear to differ in several respects. Social role theories of development assume gender differences result primarily from perceived gender roles, gender socialization and sociostructural power differentials. As a consequence, social role theorists expect gender differences in personality to be smaller in cultures with more gender egalitarianism. Several large cross‐cultural studies have generated sufficient data for evaluating these global personality predictions. Empirically, evidence suggests gender differences in most aspects of personality—Big Five traits, Dark Triad traits, self‐esteem, subjective well‐being, depression and values—are conspicuously larger in cultures with more egalitarian gender roles, gender socialization and sociopolitical gender equity. Similar patterns are evident when examining objectively measured attributes such as tested cognitive abilities and physical traits such as height and blood pressure. Social role theory appears inadequate for explaining some of the observed cultural variations in men's and women's personalities. Evolutionary theories regarding ecologically‐evoked gender differences are described that may prove more useful in explaining global variation in human personality. 相似文献
