A study in the U.S.–Mexican intergroup context examined how collective relative gratification (RG) versus deprivation affects the relationship between intergroup contact and interpersonal closeness and subtle prejudice towards an out-group. Participants were Mexican university students in Mexico (N = 239) and non-Mexican students in California (N = 90). As predicted, Mexicans experienced less gratification/higher relative deprivation (RD), and low quality intergroup contact and expressed lower interpersonal closeness and higher subtle prejudice than U.S. Americans. Differences between countries were larger amongst participants reporting higher RD. Second-stage moderated mediation analysis showed that the mediating effects of contact between country and interpersonal closeness and subtle prejudice, respectively, were larger amongst participants who felt relatively gratified than those who felt relatively deprived. These findings underline the importance of recognizing the moderating effect of differences in the RG versus RD levels of minority and majority groups when anticipating the potential benefits of intergroup contact for prejudice reduction. 相似文献

Recognition of words and kaleidoscope pictures showed a double dissociation of left and right hippocampal activity using magnetic source imaging (MSI). MSI has advantages over alternative imaging techniques that measure hemodynamic changes for identifying regional changes in brain activity in real time and on an individual subject basis without the need for image subtraction. In this study, lists of words or kaleidoscope pictures were presented for memorization followed by tests of list items and foils during which brain activity was recorded. There was greater activation in the left than the right hippocampus with abstract nouns (e.g., relief) and greater activation in the right than the left hippocampus with kaleidoscope pictures. This dissociation was evident on a case by case basis. This study demonstrates the specialization of the two medial temporal lobe (MTL) regions, including the hippocampi, for mnemonic processing of verbal and pictorial items that are difficult to encode verbally. 相似文献

Wright and Shea (1991) described intentional stimuli as explicitly identified information necessary to successfully perform a task, whereas incidental stimuli are not explicitly identified as crucial to task performance but have the potential to become associated with particular responses because of their selective presence in the training environment. Shea and Wright (1995), using a speeded-choice RT task, indicated that manipulating the strength of association between incidental information and the responses, by changing the discriminability of incidental stimuli while fixing the strength of the association between the intentional stimuli and each response, had a significant impact on task performance. The present experiment further examined the role played by incidental stimuli when the strength of association between the intentional stimuli and the associated responses was reduced, by minimising stimulus-response compatibility. It was assumed that this latter manipulation would have a similar impact as increasing the strength of incidental stimuli-response relationships. That is, the relative contribution of the incidental stimuli would increase, resulting in an increase in context-dependent behaviour during tests in which the intentional and incidental stimuli activated different responses. The results were in agreement with this prediction and consistent with a model for contextual-dependent performance proposed by Shea and Wright (1995) as well as with the outshining hypothesis forwarded by Smith (1988, 1994). 相似文献

Motor programming during practice conditions high and low in contextual interference 总被引:2,自引:0,他引:2
Immink MA Wright DL 《Journal of experimental psychology. Human perception and performance》2001,27(2):423-437
Random practice has been reported to demand greater time for movement preparation during acquisition than blocked practice. The present study revealed that this could be attributed to a more complete engagement of the motor programming process during random practice. This cost, however, was localized to the motor programming subprocess that S. T. Klapp (1995) associated with organizing the internal structure of a movement chunk rather than an alternative subprocess responsible for organizing movement chunks into the correct serial order. The more thorough employment of motor programming during acquisition by random practice participants resulted in a more efficient use of this planning operation during retention, as well as more accurate movement reproduction. These data support the claim that practice conditions high in contextual interference support improvements in both movement preparation and memory strength. 相似文献

This paper considers the role of physicaleducation researchers within current publicconcerns about body shape and weight. UsingUlrich Beck's notion of `risk' it examines howcertainty about children, obesity, exercise andhealth is produced in the contexts of `expert'knowledge and recontextualised in the academicand professional physical education literature.It is argued that the unquestioning acceptanceof the obesity discourses in physical educationhelps to construct anxieties about the body,which are detrimental to students and silencesalternative ways of thinking and doing physicaleducation. 相似文献

Recent developments in online support and counselling suggest that the users of chat rooms, for example, or the Samaritans' e-mail 'listening' service, have already discovered the power of writing as a self-help vehicle. Developments in computer-mediated counselling and therapy are essentially text-based and client-driven. The therapeutic use of expressive and reflective writing is not widely recognised in British counselling and therapy circles. The empirical foundations for the therapeutic uses of the literary arts are, however, well established. This review aims to map the use of 'writing therapy' by drawing together cross-disciplinary research and practitioner reports which might support the place of writing as a creative therapy in its own right, whether as an adjunct to face-to-face counselling or as a self-help tool. 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
Hogarth L Dickinson A Wright A Kouvaraki M Duka T 《Journal of experimental psychology. Animal behavior processes》2007,33(4):484-496
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

Mental fatigue influence on effort-related cardiovascular response: difficulty effects and extension across cognitive performance domains 总被引:2,自引:0,他引:2

Two experiments investigated cardiovascular effects of mental fatigue as a function of (1) the difficulty of the cognitive
challenge with which participants were confronted, and (2) the relevance of that challenge to the activity that instigated
the fatigue. In the first, participants performed an easy (fatigue low) or difficult (fatigue high) counting task and then
were presented an arithmetic challenge (task B relevance high) or a scanning challenge (task B relevance low) with instructions
that they would avoid a noise if they attained a modest performance standard. Analysis of blood pressure responses assessed
during the work periods revealed fatigue main effects, reflecting stronger responses for High Fatigue participants, regardless
of the character of the second task. In the second, the procedure was the same except that it included a high performance
standard and provided the chance to win a prize. Analysis of the pressure data revealed fatigue x work period interactions,
reflecting relatively stronger responses among High Fatigue participants in work period 1, but relatively weaker responses
among these participants in work period 2. Results confirm previous findings and support an analysis of fatigue influence
on effort and associated cardiovascular responses. They also argue against the idea that mental fatigue influence may be confined
to relevant cognitive performance realms.

The memory conformity effect is when people's memories become similar to one another's following a discussion. The present study examined whether an individual's beliefs in the quality of their memory, relative to another person's, mediates susceptibility to memory conformity. Perceived encoding duration was manipulated by telling dyad members that one person had encoded a set of pictures for either half or twice as long as their partner. In fact, actual encoding duration was the same for all participants. Dyad members each encoded slightly different versions of otherwise identical pictures and discussed them prior to an individual free recall test. Participants who believed that they had encoded the pictures for half as long as their partner were more susceptible to memory conformity, as indicated by their increased tendency to report errant items at test that had been encountered from their partner rather than items that they had actually seen. This effect of perceived encoding duration on memory conformity was mediated through response order. A source monitoring test found that these unseen items were errantly attributed to the pictures approximately 50% of the time. The findings are discussed in relation to the role of metamemory in susceptibility to memory conformity. 相似文献

This paper argues that the form of explanation at issue in the hard problem of consciousness is scientifically irrelevant,
despite appearances to the contrary. In particular, it is argued that the ‘sense of understanding’ that plays a critical role
in the form of explanation implicated in the hard problem provides neither a necessary nor a sufficient condition on satisfactory
scientific explanation. Considerations of the actual tools and methods available to scientists are used to make the case against
it being a necessary condition, and work by J.D. Trout that exploits psychological research on the hindsight and overconfidence
biases is used to show that it is not a sufficient condition. It is argued, however, that certain intellectual and moral concerns
give us good reason to still try to meet the hard problem’s explanatory challenge, despite its extrascientific nature. 相似文献
