Individuals in a social dilemma may experience a self-control conflict between urges to act selfishly and their better judgment to cooperate. Pairing a public goods game with a subtle framing technique, we test whether perception of self-control conflict strengthens the association between self-control and cooperation. Consistent with our hypothesis, cooperative behavior is positively associated with self-control in the treatment that raised the relative likelihood of perceiving conflict, but not associated with self-control in the treatment that lowered the likelihood. These results indicate that it is important to understand the role of self-control in cooperation.  相似文献

高校"问题学生"行为失范已得到社会的普遍关注,基于前人研究的基础,立足客观实际,开辟新视角,将社会角色理论引入对这一问题的研究,不仅对"问题学生"和"行为失范"进行了重新界定,从角色转换、角色冲突、角色错位、角色失败四个方面分析了高校"问题学生"行为失范产生的缘由,并提出了相应的对策。  相似文献

The authors integrate theoretical work on the performance of gender with a life course perspective to frame an analysis of in-depth interviews with 17 long-term married couples. The findings indicated that couples' sexual experiences are characterized by change over time, yet that change is shaped by the intersection of gender and age. Midlife couples (ages 50 - 69) were distressed by changes in their sex lives likely because they impede couples from performing gendered sexuality. The source of this distress stems from age-related physical changes; however, it manifests in different ways for husbands and wives. In contrast, later life couples (ages 70 - 86) were more likely to emphasize the importance of emotional intimacy over sex as they age. Marital sex is a source of conflict for many midlife couples because of husbands' and wives' incongruent experiences, but later life husbands and wives tend to have more congruent experiences of marital sex.  相似文献

Data from the 1999-2000 Chinese Health and Family Life Survey were merged with community-level data from the 1982, 1990, and 2000 Chinese censuses to examine the relationship between the local sex ratio (number of men per 100 women) and sexual outcomes among women (N = 1,369). Consistent with hypotheses derived from demographic-opportunity theory, multilevel logistic regression analyses showed that women are more likely to be sexually active, to have had premarital sexual intercourse, to have been forced to have sex, and to test positive for a sexually transmitted infection when there is a relative abundance of age-matched men in their local community. Education, birth cohort, and geographic location also emerged as significant predictors of women's sexual experiences.  相似文献

Objective

The aim of this study was to investigate the effect of experience of childhood abuse among university students on self-perception and submissive behavior.

Methods

The study group consisted of 646 students attending various departments of the Karadeniz Technical University Faculty of Education in Trabzon, Turkey. Participants were administered the Childhood Trauma Questionnaire, the Social Comparison Scale and the Submissive Acts Scale in a classroom setting.

Results

Analysis revealed a significant negative correlation between self-perception and all forms of abuse (physical abuse, sexual abuse, and emotional abuse and neglect), and a positive correlation between submissive behavior and all forms of abuse. The students' emotional abuse and neglect scores varied significantly according to gender, with males having higher emotional abuse and neglect scores than those of girls. Additionally, males had higher physical abuse scores than girls.

Conclusion

Childhood abuse emerged as a significant predictor of negative self-perception and submissive behavior. In addition, with the exception of sexual abuse, other forms of abuse vary according to gender. The experiences of childhood abuse may have a long-term impact on various features of character and behavior.  相似文献

Research on the functional independence of verbal operants (Skinner, 1957) has demonstrated inconsistent findings. One explanation may be that these studies have not manipulated the motivating operation (MO) to facilitate the emergence of mands (Hall & Sundberg, 1987; Lamarre & Holland, 1985). In the current study, 1 participant, diagnosed with autism, was taught to tact high-preference and low-preference leisure items, and emergence of mands was tested under varying MO conditions. Results showed the emergence of mands following periods of arranged deprivation, and greater maintenance for a highly preferred relative to a less preferred stimulus. However, mands only emerged when presession tact trials were conducted. These results suggest that in a state of deprivation, transfer of stimulus control from discriminative to motivational conditions may occur without direct training.  相似文献

Gutierrez (2006) experimentally demonstrated the effects of joint control and particularly the role of response mediation in the sequencing behavior of adults using an unfamiliar language. The purpose of the current study was to replicate and extend the procedures used by Gutierrez by comparing the effects of joint control training with the effects of a prompt-and-fade procedure on the acquisition of a sequencing task. The effects of each procedure on delayed sequencing behavior were also tested. Ten undergraduate students participated in 2 experiments. The results indicated that all participants acquired the sequencing response in fewer trials and maintained accurate delayed responding when the component responses necessary for joint control were directly taught. Finally, when the self-echoic mediation component was blocked, accurate responding deteriorated in 8 of 10 participants.  相似文献

This study was a systematic extension of Karmali, Greer, Nuzzulo-Gomez, Ross, and Rivera-Valdes (2005) and Ahearn, Clark, MacDonald, and Chung (2007). We investigated the effects of a tact correction procedure on stereotypic vocalizations in 4 children diagnosed with autism who ranged in age from 6 to 16 years. Participants had limited vocal verbal repertoires and were primarily dependent on prompts for the emission of appropriate vocalizations. A multiple-baseline design across participants was used. Data were collected on instances of stereotypic vocalizations and independent tacts during baseline conditions and on instances of stereotypic vocalizations, independent tacts, and echoic-tacts during intervention. Procedural integrity and social validity data were also obtained. The results indicated a decrease in stereotypic vocalizations for 3 of the 4 participants and a slight increase in appropriate vocal verbal behavior (i.e., tacting) for all participants. The study provides support for the use of tact correction procedures to decrease stereotypic vocalizations and increase appropriate vocalizations in children with autism.  相似文献

This study was designed to explore the grandparent-grandchild relationship from the perspective of South African adolescents, and to investigate whether grandparental involvement is independently associated with adolescents’ psychological well-being. Data were collected from 204 adolescents (mean age = 13.69) using a school-based survey. Results revealed high levels of contact between grandparents and grandchildren, although involvement varied depending on grandparent, grandchild, and family characteristics. Grandparental involvement was significantly associated with more adolescent prosocial behavior, independent of parental involvement. The findings suggest a unique association between grandparental involvement and prosocial behavior that is robust across different cultural contexts.  相似文献

Though many studies have suggested that social and behavioral skills play a central role in gender stratification processes, we know little about the extent to which these skills affect gender gaps in academic achievement. Analyzing data from the Early Child Longitudinal Study-Kindergarten Cohort, we demonstrate that social and behavioral skills have substantively important effects on academic outcomes from kindergarten through fifth grade. Gender differences in the acquisition of these skills, moreover, explain a considerable fraction of the gender gap in academic outcomes during early elementary school. Boys get roughly the same academic return to social and behavioral skills as their female peers, but girls begin school with more advanced social and behavioral skills and their skill advantage grows over time. While part of the effect may reflect an evaluation process that rewards students who better conform to school norms, our results imply that the acquisition of social and behavioral skills enhances learning as well. Our results call for a reconsideration of the family and school-level processes that produce gender gaps in social and behavioral skills and the advantages they confer for academic and later success.  相似文献
