We recently demonstrated that transient covert attention increases the apparent contrast of a stimulus (Carrasco, Ling, & Read, 2004). Schneider (2006) proposes that the observed increase in apparent contrast is largely due to sensory interactions occurring between the precue a nd stimulus,rather than to attention. Specifically, hereports that cuing effects only occur at contrasts ne ar detection threshold, and that there a re confounding sensoryinteractions between the cue and stimulus at suprathreshold detection contrasts. Our response is twofold. First, we outline the key methodological differences between our original study and Schneider's that are likely to account for the different results, and explain how we had ruled out the sensory interaction explanation of the cue. Second, we directly test the prediction put forth by Schneider. If the effects were due to sensory interactions, reversing the luminance polarity of the precue in our paradigm should lead to differential cuing effects. We replicate one of the experiments of our original study and add a condition in which the cue luminance is either black or white. Our results replicated our previous findings-they showed an increase in apparent contrast to a high-contrast stimulus when it was precued. Moreover, we found that the black cue and the white cue had the same effect, thus ruling out the alternative explanation proposed by Schneider. Transient attention does alter contrast appearance. 相似文献

The present case series with two patients explored whether virtual reality (VR) distraction could reduce claustrophobia symptoms during a mock magnetic resonance imaging (MRI) brain scan. Two patients who met DSM-IV criteria for specific phobia, situational type (i.e., claustrophobia) reported high levels of anxiety during a mock 10-min MRI procedure with no VR, and asked to terminate the scan early. The patients were randomly assigned to receive either VR or music distraction for their second scan attempt. When immersed in an illusory three-dimensional (3D) virtual world named SnowWorld, patient 1 was able to complete a 10-min mock scan with low anxiety and reported an increase in self-efficacy afterwards. Patient 2 received "music only" distraction during her second scan but was still not able to complete a 10-min scan and asked to terminate her second scan early. These results suggest that immersive VR may prove effective at temporarily reducing claustrophobia symptoms during MRI scans and music may prove less effective. 相似文献

Anxiety of childhood is a common and serious condition. The past decade has seen an increase in treatment-focussed research,
with recent trials tending to give greater attention to parents in the treatment process. This review examines the efficacy
of family-based cognitive behaviour therapy and attempts to delineate some of the factors that might have an impact on its
efficacy. The choice and timing of outcome measure, age and gender of the child, level of parental anxiety, severity and type
of child anxiety and treatment format and content are scrutinised. The main conclusions are necessarily tentative, but it
seems likely that Family Cognitive Behaviour Therapy (FCBT) is superior to no treatment, and, for some outcome measures, also
superior to Child Cognitive Behaviour Therapy (CCBT). Where FCBT is successful, the results are consistently maintained at
follow-up. It appears that where a parent is anxious, and this is not addressed, outcomes are less good. However, for children
of anxious parents, FCBT is probably more effective than CCBT. What is most clear is that large, well-designed studies, examining
these factors alone and in combination, are now needed. 相似文献

Rostral prefrontal cortex (PFC) is a large brain region, and is unusually large in humans. Therefore, it seems likely that it might support functions that are central to cognition. However, until recently, almost nothing was known about what these functions might be. The 'gateway hypothesis' places these abilities at the centre of human mental processing. It maintains that rostral PFC supports mechanisms that enable us to attend, to a novel degree, either to environmental stimuli, or by contrast, to self-generated or maintained representations (i.e. the 'thoughts in our head'). In this way, investigations into the functions of rostral PFC will reveal key new insights into how human and non-human mental abilities differ. 相似文献

Using a questionnaire survey, this study compared psychological adaptation (self-esteem, life satisfaction, and mental health problems) of Turkish adolescents in Norway and Sweden, and examined to what extent ethnic and majority identities, acculturation strategies, and perceived discrimination accounted for adaptation among Turkish adolescents. The samples consisted of 407 Turks (111 in Norway and 296 in Sweden) with a mean age of 15.2 years and 433 host adolescents (207 in Norway, 226 in Sweden) with a mean age of 15.6 years. Turks in Norway reported poorer psychological adaptation than Turks in Sweden. Predictors of good adaptation were Turkish identity and integration, whereas poor adaptation was related to marginalization and perceived discrimination. The results indicated that the poorer adaptation of Turks in Norway compared to that of Turks in Sweden could be due to lower degree of Turkish identity and higher degree of perceived discrimination. 相似文献

Ten individuals, residing in a treatment facility specializing in the rehabilitation of sex offenders with developmental disabilities, participated in an arousal assessment involving the use of the penile plethysmograph. The arousal assessments involved measuring change in penile circumference to various categories of stimuli both appropriate (adult men and women) and inappropriate (e.g., 8- to 9-year-old boys and girls). This approach extends the existing assessment literature by the use of repeated measurement and single-subject experimental design. Data from these assessments were analyzed to determine if clear and informative outcomes were obtained. Overall, three general patterns of results emerged. Some participants showed differentiated deviant arousal or higher levels of arousal to specific inappropriate stimuli (deviant is a term used in the existing sex-offender literature to describe this type of arousal). Other participants showed undifferentiated deviant arousal, in which case they showed nonspecific arousal to inappropriate stimuli. The remaining participants showed no arousal to inappropriate stimuli but did show arousal to appropriate stimuli. Implications for assessment, treatment, and future directions are discussed. 相似文献

We illustrate Fairweather's approach to Experimental Social Innovation and Dissemination with two experimental studies of programs to reduce homelessness for 168 and 225 people with mental illness and often substance abuse. Literally homeless participants were randomly assigned to programs that emphasized consumer choice or to the usual continuum of care, in which housing and services are contingent on sobriety and progress in treatment. A drop-in center that eliminated barriers to access to services was more successful than control programs in reducing homelessness, but after 24 months only 38% of participants had moved to community housing. A subsequent apartment program, in which individuals in the experimental condition moved to subsidized apartments directly from the street, with services under their control, had 79% in stable housing (compared to 27% in the control group) at the end of 6 months. Groups in this study did not differ on substance abuse or psychosocial outcomes. 相似文献

Does emotion affect how people see? We investigated the effects of emotion and attention, as well as their conjoint effect, on contrast sensitivity, a dimension of early vision. We manipulated the emotional valence and the attentional distribution of cues preceding a target stimulus and asked observers to judge the orientation of the target as contrast varied. This study provides the first behavioral evidence that (a) emotion enhances contrast sensitivity irrespective of attention and (b) emotion potentiates the effect of attention on contrast sensitivity. 相似文献

Metaphors can be understood in either of two ways: via a comparison process or via a categorization process. What determines which process will be used? According to a recent variant of comparison theory, novel metaphors must be processed as comparisons; only conventional metaphors can be processed as categorizations. We argue that choice of process is determined not by conventionality, but instead by the semantic and referential properties of the metaphor itself. We identified a type of novel metaphor that is indeed understood more quickly as a comparison than as a categorization. We then generated variants of such metaphors to make comparison difficult and found that these new novel metaphors were understood more quickly as categorizations than as comparisons. We conclude that metaphors can be processed as categorizations from the start, depending on their semantic and referential properties. 相似文献
