In contemporary theorizing, there is a controversy about the role of spatial location in the selection of visual information; some theories postulate that position plays a unique role, whereas other theories hold that position is just one selection dimension that is not different from other dimensions, such as color and shape. In this context, a paradigm introduced by Tsal and Lavie (1988) promised to be of fundamental importance. With that paradigm, Tsal and Lavie found that, after reporting a first letter of a prespecified color, subjects preferred to switch their reporting to letters from array positions adjacent to that letter over continuing to report letters of the same color as that of the first letter. This switch from color to position provided firm evidence in favor of the “position-special” views as opposed to the “all-attributes-are-equal” views. In the present study, six experiments, employing Tsal and Lavie’s paradigm and variations of that paradigm, are reported. Experiments 1, 2, 4, and 5 show that evidence for a switch from selection on the basis of color to selection on the basis of position is not obtained when subjects are forced to fixate the fixation point and possibly also not under normal contrast conditions without fixation controls. Experiment 3 shows that switching from color to position is difficult. Experiments 2, 5, and 6 show that evidence for a switch is obtained only under low-contrast conditions when subjects are not forced to fixate the fixation point. It is concluded that the Tsal and Lavie paradigm is an asymmetric paradigm. The results reported by Tsal and Lavie constituted a major threat for the “all-attributes-are-equal” theories and provided firm support for the “position-special” theories. The results reported in the present study are compatible with the all-attributes-are-equal theories, but, at the same time, do not constitute a major threat for the contemporary position-special theories.  相似文献

Historically, researchers have sought to identify environmental causes of employee turnover. This paradigm has led to the underemphasis of individual differences as being an important cause of individuals' turnover decisions. The results of the meta-analysis show that personality traits do have an impact on individuals' turnover intentions and behaviors. The trait of Emotional Stability best predicted (negatively) employees' intentions to quit, whereas the traits of Conscientiousness and Agreeableness best predicted (negatively) actual turnover decisions. A theoretically developed path model showed important direct effects from personality to intentions to quit and turnover behaviors that were not captured through job satisfaction or job performance. These direct effects indicate that employees who are low on Emotional Stability may intend to quit for reasons other than dissatisfaction with their jobs or not being able to perform their jobs well. The direct effects on turnover suggest that individuals who are low on Agreeableness or high on Openness may engage in unplanned quitting. Personality traits had stronger relationships with outcomes than did non-self-report measures of job complexity/job characteristics.  相似文献

Existing transformational leadership research has focused primarily on the behaviors of leaders and their effects on followers. The authors extended this research by examining the social networks of managers who exhibit transformational leadership behaviors. Their focus was on the network of relationships that managers develop and whether they hold key positions in the organization's informal social networks. In a field study using data from 39 managers and 130 nonmanagement employees of 6 organizations, the authors found that managers who score higher on transformational leadership tend to hold more central positions in organizational advice and influence networks. Furthermore, the direct reports of these leaders were also more central in informal organizational networks. These results illuminate one of the ways that managers who exhibit transformational leadership behaviors may exert influence in organizations.  相似文献

In this study we tested 4-, 9-, 12-, and 18-month-old C57BL/6 mice in the 250-msec delay eyeblink classical conditioning procedure to study age-related changes in a form of associative learning. The short life expectancy of mice, complete knowledge about the mouse genome, and the availability of transgenic and knock-out mouse models of age-related impairments make the mouse an excellent species for expanding knowledge on the neurobiologically and behaviorally well-characterized eyeblink classical conditioning paradigm. Based on previous research with delay eyeblink conditioning in rabbits and humans, we predicted that mice would be impaired on this cerebellar-dependent associative learning task in middle-age, at ~9 months. To fully examine age differences in behavior in mice, we used a battery of additional behavioral measures with which to compare young and older mice. These behaviors included the acoustic startle response, prepulse inhibition, rotorod, and the Morris water maze. Mice began to show impairment in cerebellar-dependent tasks such as rotorod and eyeblink conditioning at 9 to 12 months of age. Performance in hippocampally dependent tasks was not impaired in any group, including 18-month-old mice. These results in mice support results in other species, indicating that cerebellar-dependent tasks show age-related deficits earlier in adulthood than do hippocampally dependent tasks.  相似文献

This article is concerned with the relationships which hold between the clinical practice and the theory of family therapy; and between these and academic research. These relationships are seen as tenuous and thin because, in the first place, there is a lack of rigorous theoretical underpinning; and second, the research methods employed do not fit in with current family therapy practice, and with the theory that underlies this practice. The role of the concept of narrative process modes is proposed as a bridging and mediating one. The external, internal and reflective narrative process modes are seen as relevant from the point of view of family therapy process research, and the clinical practice of marital and family therapy.  相似文献

Despite a well‐documented connection between religion and mortality, the link between religion and obesity‐related outcomes and behaviors has not been adequately studied, particularly among adolescents. This study examines whether self‐reported religious beliefs influence decisions about physical activity and diet in a sample of Jewish adolescents (n = 351). The results show that reporting a stronger influence of religious beliefs on health behaviors is associated with behaviors related to physical activity, but not diet. In adjusted regression models, individuals who report that their religious beliefs influence decisions about being physically active “a lot” have significantly more active days per week than those who say their religious beliefs do not influence such decisions. Similar effects are seen with regard to the students’ overall amount of sedentary time. The results shed light on previously documented relationships between religion and health, provide practical implications for religious organizations and leaders, and suggest areas for future research.  相似文献

Three propositions that are central to J. R. Harris's group socialization theory (1995, 1998) are considered in this review. These propositions are as follows: (a) Parental behaviors have no long-term effects on children's psychological characteristics, (b) peer groups are the primary environmental influence on psychological functioning, and (c) dyadic relationships are situation-specific and do not generalize. The evidence that J. R. Harris has outlined in support of each of these propositions is reviewed, as is additional empirical research not considered by J. R. Harris. Serious limitations to each proposition are identified. The available evidence is more consistent with a model of multiple socialization agents. An expanded research agenda that permits a more definitive test of J. R. Harris's propositions and social relationship theory is proposed.  相似文献

Double video paradigm (DVP) studies have found contradictory evidence regarding the young infants' ability to discriminate their mother's 'replay' image from 'live'. This study examined the hypothesis that 4-month-old infants whose mothers showed high-levels-of-playful-behavior are more likely to discriminate social contingency in the DVP. We also examined the relationships between the infants' DVP behaviors and mothers' free-play behaviors at home with their 3-month-old infants. The results supported our hypothesis. Further, when the mothers' behaviors were reduced to playful companion (PC) and sensitive support (SS) by a principal component analysis, the level of PC was closely related to the infants' detection of social contingency, but SS was not. The different functions of mothers' 'playfulness' and 'sensitivity' in communication with their infants are discussed.  相似文献

The Stroop effect is one of the most famous examples of interference in human perception. The present study demonstrates that a position Stroop paradigm, comparable to the classical color-word interference paradigm, resulted in the same pattern of interference for the spatial dimension; however, the interference was significantly weaker. By exchanging the original oral response for a manual response in the spatial paradigm, we showed that the verbal component is crucial for the Stroop effect: Manual responses lead to a disappearance of the interference effect. Moreover, with manual responses word position was recognized at the same speed for the baseline condition and for words that were incongruent as well as congruent with the spatial position. The results indicate (1) that the Stoop effect depends heavily on verbal components and (2) that differing processing speeds between reading and position recognition do not serve as a proper explanation for the effect. In addition, the provided paradigm plausibly transfers the classical color-word interference to the spatial dimension.  相似文献

This study examines the relationship between television viewing and sex role attitudes/behaviors from the perspective of cultivation theory. It uses a sample of fourth- and fifth grade children to examine if television viewing is related to children's attitudes and behaviors in relation to household chores that are typically viewed as something boys do or something girls do. The sample was equally divided into fourth and fifth graders as well as boys and girls; the racial distribution was 64% white, 21% black, and 14% other races. There were statistically significant relationships between television viewing and scores on an index of attitudes toward sex-stereotyped chores that maintained statistical significance under conditions of multiple controls. Although viewing was not related to which chores the children actually performed, there were statistically significant relationships between attitudes, behaviors, and viewing. For both the boys and girls there were moderate to strong statistically significant relationships which increased with television viewing, between attitudes about who should do certain chores, and about whether or not the children said they did chores typically associated with the other sex.  相似文献

This study evaluated whether behaviors often taught as part of social skills training are judged favorably by others. Community judges evaluated the performances of people in various situations requiring one of three social skills: following instructions, accepting criticism, and negotiating to resolve conflicts. These skills were displayed in videotaped scenes by actors with and without mental retardation who acted out roles that had different types of authority relationships, and when different components or clusters of behavior (nonverbal, specific verbal, or general verbal behaviors) were performed well or poorly. The highest ratings by judges were of videotaped scenes that depicted correct use of all behaviors, regardless of which skill was being examined, whether or not the actor had mental retardation, or what the relationship was between the two actors. The lowest ratings were of videotaped scenes that depicted poor performance of all behaviors, and intermediate ratings were obtained when only some of the behaviors were performed poorly. These results, as well as the verbal responses of judges to questions, indicated that the different behaviors commonly used in teaching the skills of following instructions, accepting criticism, and negotiating are relevant to judgment of social performance, and are likely to be reinforced and maintained by social contingencies.  相似文献

外貌吸引力对亲密关系的建立和发展发挥着不可忽视的作用。由于高外貌吸引力个体被认为具有更多的社会理想特质和更优良的基因, 因此被视为具有更高的配偶价值, 从而有效地促进亲密关系的建立。然而在亲密关系发展中, 由于不匹配的外貌吸引力引起低外貌吸引力伴侣采取一系列的伴侣保留、嫉妒、侮辱和性强迫行为, 从而加速亲密关系的破裂。也有研究指出高外貌吸引力男性可能不具有良好的基因, 而女性也不会在繁殖高峰期偏爱高外貌吸引力男性。“美的就是好的”的看法正在受到质疑, 研究结果也已引发了诸多争议和分歧, 相关的直接证据亦有待进一步夯实。  相似文献

In order to investigate the relationships between mousekilling and conspecific aggression, behavioral variables of killer and nonkiller rats were compared in a “resident-intruder” paradigm, in resident as well as in intruder animals. The occurrence of offensive items (offensive sideways, attack) was significantly higher in killer rats when they were residents; their corresponding opponents displayed more defensive behaviors. No significant difference in aggressive behaviors was noted when the comparison was done in the intruders. These results and those of previous studies suggest that there is a correlation between mousekilling and intraspecific offensive behaviors. Some similarities in the situations where both behaviors are elicited–eg, introduction of an unfamiliar intruder into a familiar environment–may contribute to the existence of such a correlation and the possibility of common mechanisms underlying both behaviors is discussed.  相似文献

What leads some women to form romantic and sexual relationships with men, and other women to form intimate relationships with women? This article presents a new conceptual paradigm for understanding women's sexual orientation that is emerging from research in such diverse fields as social psychology, sex research, evolutionary psychology, attachment theory, and neuroscience. This approach acknowledges the potential plasticity of women's sexuality and the emphasis that women place on close relationships as a context for sexuality. Research also raises the possibility that for women the biological determinants of sexual desire, attraction, and attachment are not inherently linked to a partner's gender. This article begins with a brief survey of research on women's same‐sex romantic and sexual relationships not only in the United States today but also in other cultures and historical periods. These and other findings are used to critique prevailing conceptual models of women's sexual orientation. Finally, key elements in an alternative paradigm are described.  相似文献

The purpose of the present study was twofold: (1) to review empirical studies published between 1966-1995 utilizing J. E. Marcia's [(1966) “Development and Validation of Ego Identity Status,” Journal of Personality and Social Psychology, Vol. 3, pp. 551–558] identity status paradigm for the purpose of observing any patterns of gender difference on issues related to identity structure, content, and context; (2) to present results of a single empirical study that examined the question of possible gender differences in how relationships are used in the identity formation process. Results of the review indicated few gender differences in identity structure, content, developmental process, and context; only the domains of sexuality and family roles may hold greater salience for women than men. Results from the single empirical investigation found identity status, rather than gender, to be associated with how relationships were used in the identity formation process. A discussion of possible future research directions on gender and identity status is presented.  相似文献
