Much work has been done to investigate participants' ability to detect repeated targets, but the presentstudy examined the influence of recently attended stimuli on target masking. Participants performed a target identification task in which the item that masked the target was either a recently attended item or a novel item. When it was identical to a previously attended stimulus, the mask was rendered considerably less effective. We have termed this effect a repeated mask reduction (RMR). This simple manipulation resulted in a large, reliable effect on the efficacy of visual masking in a single-target identification paradigm. In Experiments 1, 2, and 3, we demonstrated the basic effect and noted that the RMR increased as task difficulty increased. Experiments 4 and 5 suggested that attention to the first instance of the mask was crucial to this effect by showing that the magnitude of the RMR was unaffected by repetition of nonmask distractors and that the magnitude of the effect was reduced when less attention was paid to the first instance of the mask. 相似文献

Instructors of personality assessment are challenged with teaching students how to execute the tacit thinking skills necessary to make sound test interpretations. The author provides a concrete tool for teaching students how to make interpretive inferences from verbal personality test data utilizing the construct of verbal abstract reasoning. Applied specifically to Thematic Apperception Test interpretation, the author discusses how the construct of verbal abstract reasoning can be utilized: as a model for providing explicit instruction on the implicit process of drawing inferences in test interpretation; for grounding students in data when constructing interpretations and avoiding making overpersonalized interpretations; as a means of basing interpretations on a convergence of data; as a means of gauging the level of confidence one can place in interpretations; and for understanding inferences drawn from other tests, such as the Rorschach. 相似文献

Aversive conditioning and extinction were evaluated in children with anxiety disorders (n=23), at-risk for anxiety disorders (n=15), and controls (n=11). Participants underwent 16 trials of discriminative conditioning of two geometric figures, with (CS+) or without (CS-) an aversive tone (US), followed by 8 extinction trials (4 CS+, 4 CS-), and 8 extinction re-test trials averaging 2 weeks later. Skin conductance responses and verbal ratings of valence and arousal to the CS+/CS- stimuli were measured. Anxiety disordered children showed larger anticipatory and unconditional skin conductance responses across conditioning, and larger orienting and anticipatory skin conductance responses across extinction and extinction re-test, all to the CS+ and CS-, relative to controls. At-risk children showed larger unconditional responses during conditioning, larger orienting responses during the first block of extinction, and larger anticipatory responses during extinction re-test, all to the CS+ and CS-, relative to controls. Also, anxiety disordered children rated the CS+ as more unpleasant than the other groups. Elevated skin conductance responses to signals of threat (CS+) and signals of safety (CS-; CS+ during extinction) are discussed as features of manifestation of and risk for anxiety in children, compared to the specificity of valence judgments to the manifestation of anxiety. 相似文献

The perception of a face allows us to recognize the person, infer his or her emotional state, better understand what the person is saying, and derive general information, such as age and gender. This unique visual stimulus has generated a wealth of research, and subsequently theoretical and methodological debate. This special issue brings together 16 original papers that show the extraordinary diversity and fruitfulness of the approaches now being pursued. They are aimed at understanding different aspects of face perception in populations ranging from healthy children to adults with brain lesions and with techniques covering the entire spectrum from paper‐and‐pencil tests to functional brain imaging. Together, these contributions provide an insightful overview of the current state of research on face perception and exemplify the questions that dominate the field. To one such question, whether ‘face perception’ is a special issue in the broad field of the cognitive neurosciences, the answer is clearly yes! 相似文献

Data from 363 male smokeless tobacco users and their romantic partners were analyzed to discern the role of support in cessation. Women reported playing a part in enrollment (71%), and more than half examined program materials or discussed cessation activities with the chewers. Women's reports of delivered support correlated substantially with men's experience of received support. Men's received positive support predicted abstinence at 6-month follow-up (odds ratio = 1.29, confidence interval = 1.03-1.61) and more than 24 hr of abstinence for those still using tobacco at 6 months (odds ratio = 1.75, confidence interval = 1.30-2.36) and moderated the effect of baseline depression and addiction on abstinence. Women played a major role through all stages of cessation. 相似文献

Physicians used either an autonomy-supportive or a controlling interpersonal style to counsel smokers based on National Cancer Institute guidelines. Physician autonomy support was rated from audiotapes, and patients' perceived competence and autonomous motivation for quitting were self-reported on questionnaires. Validated point prevalences for 6, 12, and 30 months and for continuous cessation were examined. The intervention did not have a direct effect on quit rates; however, structural equation modeling supported the self-determination process model of smoking cessation. The model indicated that the autonomy-supportive intervention was rated as more autonomy supportive, that rated autonomy support predicted autonomous motivation, and that autonomous motivation predicted cessation at all points in time. Perceived competence contributed independent variance to cessation only at 6 months. 相似文献

Investigations of patterning discriminations by nonhuman animals have generally found that positive patterning is easier to learn than negative patterning. Studies of patterning discriminations in human causal learning tasks have failed to document any differences between positive and negative patterning. In the present study, human participants predicted an outcome on trials involving either a compound cue or its elements. Positive and negative patterning problems were successfully solved in a within-subjects design; negative patterning problems proved to be more difficult when an additional, 50% contingent cue was included (Experiment 2), but not when it was excluded (Experiment 1). Possible reasons for these results are discussed. The discussion concludes with an analysis of exemplar models (e.g., Pearce, 1994) of human causal learning and considers the conditions under which these models do and do not anticipate our results. 相似文献
