Relational learning with and without awareness: Transitive inference using nonverbal stimuli in humans 总被引:5,自引:0,他引:5

Learning complex relationships among items and representing them flexibly have been shown to be highly similar in function and structure to conscious forms of learning. However, it is unclear whether conscious learning is essential for the exhibition of flexibility in learning. Successful performance on the transitive inference task requires representational flexibility. Participants learned four overlapping premise pairs (A > B, B > C, C > D, D > E) that could be encoded separately or as a sequential hierarchy (A > B > C > D > E). Some participants (informed) were told prior to training that the task required an inference made from premise pairs. Other participants (uninformed) were told simply that they were to learn a series of pairs by trial and error. Testing consisted of unreinforced trials that included the non-adjacent pair, B versus D, to assess capacity for transitive inference. Not surprisingly, those in the informed condition outperformed those in the uninformed condition. After completion of training and testing, uninformed participants were given a postexperimental questionnaire to assess awareness of the task structure. In contrast with expectations, successful performance on the transitive inference task for uninformed participants does not depend on or correlate with postexperimental awareness. The present results suggest that relational learning tasks do not necessarily require conscious processes. 相似文献

Participants (168 female and 118 male undergraduate students) completed a brief questionnaire, a measure of perceived educational and career‐related barriers, and a measure of coping efficacy. As expected, women and ethnic minorities anticipated significantly more career‐related barriers than did men and European American students, respectively. Ethnic minorities also exhibited more perceived educational barriers and lower self‐efficacy for coping with perceived career‐related barriers relative to their European American counterparts. Findings are discussed in terms of their theoretical implications and practical career counseling applications. 相似文献

Walton's Argumentation Schemes for Presumptive Reasoning: A Critique and Development 总被引:3,自引:0,他引:3
J. Anthony Blair 《Argumentation》2001,15(4):365-379
The aim of the paper is to advance the theory of argument or inference schemes by suggesting answers to questions raised by Walton's Argumentation Schemes for Presumptive Reasoning (1996), specifically on: the relation between argument and reasoning; distinguishing deductive from presumptive schemes, the origin of schemes and the probative force of their use; and the motivation and justification for their associated critical questions. 相似文献

This study examined headache characteristics and psychological variables associated with pediatric headache in a specialty treatment clinic. Children were referred by pediatric neurologists to a hospital-based pediatric behavioral medicine clinic for behavioral treatment in conjunction with medical management of the pain. Headache typology of the children indicated that 1/3 of the sample reported at least daily headaches, and a large percentage of patients described experiencing headaches that lasted for more than a day (26%). Child and parent report of pain revealed a fairly high level of correspondence for headache activity. Regarding other psychological characteristics, children in this study endorsed higher than expected levels of somatization even after adjusting for headache symptoms. Compared with children's report, parents' report showed only slightly higher levels of secondary gain experienced by children because of pain. Gender differences were not found. The implications of these findings for improving our understanding of pediatric headache are discussed. 相似文献

Research has shown that, under certain conditions, people with a strong belief in a just world (BJW) perceive themselves to be less at risk for serious negative events (e.g., contracting AIDS). We extended this work by investigating the relation between BJW and high‐risk sexual behavior Gay and bisexual men (N= 102) responded to a questionnaire that measured individual differences in BJW, personality characteristics related to perceived relationship threat (e.g., interpersonal control), and frequency of condom use and anal intercourse. Results generally supported predictions. For example, among respondents low in interpersonal control, a strong BJW was associated with less frequent condom use. These results have implications for research on BJW, as well as research on the predictors of high‐risk sexual behavior. 相似文献

Three experiments examined the ability of birds to discriminate between the actions of walking forwards and backwards as demonstrated by video clips of a human walking a dog. Experiment 1 revealed that budgerigars (Melopsittacus undulates) could discriminate between these actions when the demonstrators moved consistently from left to right. Test trials then revealed that the discrimination transferred, without additional training, to clips of the demonstrators moving from right to left. Experiment 2 replicated the findings from Experiment 1 except that the demonstrators walked as if on a treadmill in the center of the display screen. The results from the first 2 experiments were replicated with pigeons in Experiment 3. The results cannot be explained if it is assumed that animals rely on static cues, such as those derived from individual postures, in order to discriminate between the actions of another animal. Instead, this type of discrimination appears to be controlled by dynamic cues derived from changes in the posture of the demonstrators. 相似文献

The role of drug expectancy in the control of human drug seeking 总被引:2,自引:0,他引:2

Human drug seeking may be goal directed in the sense that it is mediated by a mental representation of the drug or habitual in the sense that it is elicited by drug-paired cues directly. To test these 2 accounts, the authors assessed whether a drug-paired stimulus (S+) would transfer control to an independently trained drug-seeking response. Smokers were trained on an instrumental discrimination that established a tobacco S+ in Experiment 1 and a tobacco and a money S+ in Experiment 2 that elicited an expectancy of their respective outcomes. Participants then learned 2 new instrumental responses, 1 for each outcome, in the absence of these stimuli. Finally, in the transfer test, each S+ was found to augment performance of the new instrumental response that was trained with the same outcome. This outcome-specific transfer effect indicates that drug-paired stimuli controlled human drug seeking via a representation or expectation of the drug rather than through a direct stimulus-response association. 相似文献
