The bivalency effect is a block-wise response slowing that is observed during task-switching when rare stimuli that cue two tasks (bivalent stimuli) are encountered. This adjustment in response style affects all trials that follow bivalent stimuli, including those trials that do not share any features with bivalent stimuli. However, the specific stimulus and response properties that trigger the bivalency effect are not well understood. In typical bivalency effect experiments, bivalent stimuli can be congruent or incongruent with respect to the response afforded by the irrelevant stimulus feature, and this distinction has never been examined. In the present study, we show that cognitive load defined by the response incongruence on bivalent trials plays a critical role in producing the subsequent response slowing observed in the bivalency effect, as well as maintaining the magnitude of the bivalency effect across practice. We propose that the bivalency effect reflects a process involved in predicting future cognitive load based on recent cognitive load experience. This is in line with a recent proposal for a role of the ACC in monitoring ongoing changes in the environment to optimize future performance (Sheth et al., in Nature 488:218–221, 2012).  相似文献

Our quasi-experimental, longitudinal treatment study examined whether Attributional Retraining (AR) facilitated adjustment among young adults (n = 324) making the challenging school-to-university transition. An AR by performance orientation group 2 × 4 design showed AR primarily benefited high-risk students: Failure-ruminators (high failure preoccupation, low perceived control) receiving AR reported higher intrinsic motivation and more adaptive attribution-related emotions than their no-AR peers. Failure-acceptors (low failure preoccupation, low perceived control) receiving AR had higher intrinsic motivation, higher grade point averages, and fewer course withdrawals than their no-AR counterparts. Thus, AR had differential benefits (emotions, achievement) for vulnerable students who were psychologically distinct.  相似文献

In this 15-year longitudinal study the authors investigated individual and contextual factors that predispose adolescents from a disadvantaged urban area to drug dependence in adulthood. Adolescents were recruited from schools serving East Harlem in New York City. Of the 838 participants followed to adulthood, 59% were women, 55% were African American, and 45% were Puerto Rican. Self-report data were obtained on externalizing and internalizing problems, substance use, and contextual influences across adolescence and young adulthood. Drug dependence was assessed in adulthood. Multivariate logistic regressions of drug dependence were performed on the whole sample and separately by gender. Each of the domains was associated with adult drug dependence. Although mean gender differences were found, most associations of risk factors with drug dependence did not vary significantly by gender. Treating externalizing and internalizing problems, reducing substance use, and providing coping skills for adverse contextual influences in adolescence and young adulthood may reduce the likelihood of becoming drug dependent in adulthood.  相似文献

In the United States, adult entertainment striptease (also called exotic dance, nude dancing, and topless dancing) has both live and imaginary spectators. The real audience consists of those who actually enter a club (cabaret, theater), such as patrons and club personnel. However, there are people who only imagine what exotic dance is. I will comment on real and imaginary exotic dance spectators, the values they have, the actions they take that impact exotic dance, and the implications of these actions. A mosaic of contested meanings of exotic dance affects its existence or modification as well as American civil liberties. There are some feminist and uninformed imaginary spectators. Most active is an absent, imaginary audience of a segment of the politically active Christian Right that adheres to its interpretation of Scripture. Imaginary spectators are usually blind and deaf to the actual language of a dance form. Some believe exotic dance to be sinful and/or to cause crime, property depreciation, and disease, contrary to scientific evidence. These spectators’ actions in many places have destroyed the contemporary genre of exotic dance, hurt the industry economically, and caused the loss of jobs. Actual spectators, patrons who expect to see the same full nudity and sexy dance movements that are seen in “high” (“elite”) forms of art such as ballet, opera, modern dance, and theater, believe in free expression and unfettered enterprise and join the defense of exotic dance.  相似文献

As the Journal of Media and Religion (JMR) begins its seventh year, the editors pause to reflect on research directions and make recommendations for future research. Based on studies in JMR and other sources, three research approaches are identified: (1) The Proliferation of Mediated Religion, or the idea that media are creating multiple places of worship beyond the physical walls of traditional congregations, (2) Religious Audiences as Interpretive Communities, where shared interpretations of popular media content are increasingly important in understanding religious groups, and (3) Media Criticism drawing on the cultural aspects of religion in critiquing media genres and texts.

A dominant theme across the three approaches is that individuals are increasingly willing to have religious experiences through media of popular culture. The numinous is recommended as an integrative concept to facilitate research of new forms of mediated religion.  相似文献

Three models (independent, interdependent, and mediational) were hypothesized in this study, to examine the interrelation of personality, family, and peer determinants and their effects on tobacco use by young adults. Mothers were first interviewed about their children when they were between the ages of 1 and 10 years old. Three subsequent interviews were conducted with the children when they reached adolescence and young adulthood. Results show support for the mediational model. In accordance with family interactional framework conceptions, there was a sequence in patterning: from parenting during early adolescence; to personality and peer factors, extending to smoking in late adolescence; and culminating in smoking in adulthood. With a developmental approach, a number of psychosocial measures were related in both younger and older children. Nevertheless, some interesting developmental differences emerged. The findings suggest at least four possible targets for therapeutic or preventive intervention: the parent, the child, the adolescent, and the peer group.  相似文献

The interrelationship of sets of father and daughter factors in explaining depressive mood in normal female adolescents was examined. Separate questionnaires were given to 403 college students and their fathers. A mediational model was found, in which two sets of paternal variables were related to the daughter personality set, which in turn was related to her depressive mood. In addition, protective personality attributes of the daughter served both to offset the impact of paternal risk factors and to further strengthen paternal protective factors to reduce frequency of depressive mood. Comparisons are made with an earlier study of sons' depressive mood (Brook, Brook, Whiteman, & Gordon, 1983).  相似文献

Remembering the distance or end-location of an interpolated movement interfered equally with the retention of criterion movement end-location. Interpolated distances were recalled less well than interpolated locations. These results were interpreted as evidence of capacity interference rather than structural interference with a visual/kinesthetic integrated store.  相似文献

Inductive learning and reasoning, as we use it both in everyday life and in science, is characterized by flexible inferences based on statistical information: inferences from populations to samples and vice versa. Many forms of such statistical reasoning have been found to develop late in human ontogeny, depending on formal education and language, and to be fragile even in adults. New revolutionary research, however, suggests that even preverbal human infants make use of intuitive statistics. Here, we conducted the first investigation of such intuitive statistical reasoning with non-human primates. In a series of 7 experiments, Bonobos, Chimpanzees, Gorillas and Orangutans drew flexible statistical inferences from populations to samples. These inferences, furthermore, were truly based on statistical information regarding the relative frequency distributions in a population, and not on absolute frequencies. Intuitive statistics in its most basic form is thus an evolutionarily more ancient rather than a uniquely human capacity.  相似文献
