A feature of depression is the distressing experience of intrusive, negative memories. The maladaptive appraisals of such intrusions have been associated with symptom persistence. This study aimed to experimentally manipulate appraisals about depressive intrusions via a novel computerized cognitive bias modification (CBM) of appraisals paradigm, and to test the impact on depressive intrusion frequency for a standardized event (a depressive film). Forty-eight participants were randomly assigned to either a session of positive or negative CBM. Participants then watched a depressing film (including scenes of bereavement and bullying) and subsequently monitored the occurrence of depressive intrusions related to the film in a diary for one week. At one-week follow-up, participants completed additional measures of intrusions – the Impact of Event Scale (IES) and an intrusion provocation task. As predicted, compared to the negative condition, participants who underwent positive CBM showed a more positive appraisal bias. Further, one week later, positive CBM participants reported fewer intrusions of the film and had lower IES scores. Our findings demonstrate that it is possible to manipulate maladaptive appraisals about depressive intrusions via a computerized CBM task. Further, this effect transfers to reducing intrusive symptomatology related to a standardized event (a depressive film) over one week, suggesting novel clinical implications. 相似文献

Recognition of natural scenes from global properties: seeing the forest without representing the trees 总被引:1,自引:0,他引:1
Human observers are able to rapidly and accurately categorize natural scenes, but the representation mediating this feat is still unknown. Here we propose a framework of rapid scene categorization that does not segment a scene into objects and instead uses a vocabulary of global, ecological properties that describe spatial and functional aspects of scene space (such as navigability or mean depth). In Experiment 1, we obtained ground truth rankings on global properties for use in Experiments 2-4. To what extent do human observers use global property information when rapidly categorizing natural scenes? In Experiment 2, we found that global property resemblance was a strong predictor of both false alarm rates and reaction times in a rapid scene categorization experiment. To what extent is global property information alone a sufficient predictor of rapid natural scene categorization? In Experiment 3, we found that the performance of a classifier representing only these properties is indistinguishable from human performance in a rapid scene categorization task in terms of both accuracy and false alarms. To what extent is this high predictability unique to a global property representation? In Experiment 4, we compared two models that represent scene object information to human categorization performance and found that these models had lower fidelity at representing the patterns of performance than the global property model. These results provide support for the hypothesis that rapid categorization of natural scenes may not be mediated primarily though objects and parts, but also through global properties of structure and affordance. 相似文献

The current study examined the accuracy of the multiple-stimulus without replacement (MSWO) preference assessment for identifying preferred common classroom activities as reinforcers with children with behavioral disorders. The accuracy of predictions from the MSWO regarding high, medium, and low stimulus preference was tested by providing contingent access to activities for completing math problems within an independent seatwork format. Overall, there was an interaction effect between preference ranking (high, medium, or low) and number of problems completed. The results confirm and extend previous findings regarding the accuracy of predictions with the MSWO. The findings also reveal, however, some individual differences that may account for instances in which student behavior did not conform to predictions of stimulus preference assessments. 相似文献

The five articles in this special section examine personality and racial/ethnic relations from the perspective of Mischel and Shoda's Cognitive–Affective Personality System (CAPS) Theory. In this introductory piece, we first provide a primer on CAPS theory. In particular, we try to highlight the role that context plays in the construction and manifestation of personality as well as the dynamic ways that people interpret and react to input from their environment. We then review research on race-based rejection sensitivity as a programmatic illustration of the role expectancies play in racial/ethnic relations. Finally, we summarize and tie together the articles that comprise this section via a set of emergent themes that are common to the present contributions. 相似文献

In four experiments, we investigated the effect of giving rats exposure to a distinctive environmental context before a phase of training in which an injection of LiCl was paired with that context. The results of Experiments 1 and 2 were consistent with the possibility that such preexposure served to retard subsequent conditioning to the context (i.e., produced a latent inhibition effect). Experiments 3 and 4 demonstrated that allowing the rats to consume a novel-flavored solution during preexposure enhanced the latent inhibition effect. The relevance of these findings both for theories of latent inhibition and for the use of preexposure as a clinical intervention for the reduction of conditioned nausea in humans is considered. 相似文献

In two experiments, we examined age differences in collaborative inhibition (reduced recall in pairs of people, relative to
pooled individuals) across repeated retrieval attempts. Younger and older adults studied categorized word lists and were then
given two consecutive recall tests and a recognition test. On the first recall test, the subjects were given free-report cued
recall or forced-report cued recall instructions (Experiment 1) or free recall instructions (Experiment 2) and recalled the
lists either alone or in collaboration with another subject of the same age group. Free-report cued recall and free recall
instructions warned the subjects not to guess, whereas forcedreport cued recall instructions required them to guess. Collaborative
inhibition was obtained for both younger and older adults on initial tests of free-report cued recall, forced-report cued
recall, and free recall, showing that the effect generalizes across several tests for both younger and older adults. Collaborative
inhibition did not persist on subsequent individual recall or recognition tests for list items. Older adults consistently
falsely recalled and recognized items more than did younger adults, as had been found in previous studies. In addition, prior
collaboration may exaggerate older adults’ tendency toward higher false alarms on a subsequent recognition test, but only
after a free recall test. The results provide generality to the phenomenon of collaborative inhibition and can be explained
by invoking concepts of strategy disruption and source monitoring. 相似文献

Limited research has been conducted on the structure of the pars triangularis (PT) in dyslexia despite functional neuroimaging research finding it may play a role in phonological processing. Furthermore, research to date has not examined PT size in ADHD even though the right inferior frontal region has been implicated in the disorder. Hence, one of the purposes of this study was to examine the structure of the PT in dyslexia and ADHD. The other purposes included examining the PT in relation to overall expressive language ability and in relation to several specific linguistic functions given language functioning often is affected in both dyslexia and ADHD. Participants included 50 children: 10 with dyslexia, 15 with comorbid dyslexia/ADHD, 15 with ADHD, and 10 controls. Using a 2 (dyslexia or not) × 2 (ADHD or not) MANCOVA, findings revealed PT length and shape were comparable between those with and without dyslexia. However, children with ADHD had smaller right PT lengths than those without ADHD, and right anterior ascending ramus length was related to attention problems in the total sample. In terms of linguistic functioning, presence of an extra sulcus in the left PT was related to poor expressive language ability. In those with adequate expressive language functioning, left PT length was related to phonological awareness, phonological short-term memory and rapid automatic naming (RAN). Right PT length was related to RAN and semantic processing. Further work on PT morphology in relation to ADHD and linguistic functioning is warranted. 相似文献

Self-kindness when facing stress: The role of self-compassion,goal regulation,and support in college students’ well-being 总被引:1,自引:0,他引:1

This project brought together the constructs of goal and emotion regulation as a way of understanding college students’ well-being,
building on previous work that identified the ability to disengage in goal pursuit and to redirect energy toward alternative
goals as an important contributor to well-being. In Study 1, we assessed the amount of variance in well-being accounted for
by measures of goal management, adding to the regression measures of student stress and self-compassion, the latter defined
as a healthy form of self-acceptance and characterized as a tendency to treat oneself kindly in the face of perceived inadequacy.
In Study 2, the stress scale was replaced by measures of perceived need and availability of support. Across studies, although
factors such as goal management, stress, and need for and availability of support were important predictors of well-being,
self-compassion accounted for a significant amount of additional variance in well-being. 相似文献

It is a reasonable assumption that universal properties of natural languages are not accidental. They occur either because they are underwritten by genetic code, because they assist in language processing or language learning, or due to some combination of the two. In this paper we investigate one such language universal: the suffixing preference across the world's languages, whereby inflections tend to be added to the end of words. A corpus analysis of child-directed speech in English found that suffixes were more accurate at cuing the grammatical category of the root word than were prefixes. An artificial language experiment found that there was a learning advantage for suffixes over prefixes in terms of grammatical categorization within an artificial language. The results are consistent with an account of language universals that originate in general purpose learning mechanisms. 相似文献

The purpose of the current research was to evaluate how gender stereotypes and sexist attitudes affect responses to hypothetical job applicants. In Study 1 (N?=?93) undergraduate and graduate students in the Southwestern USA evaluated a male, female, or gender-ambiguous resume. They also completed the Ambivalent Sexism Inventory (ASI; Glick and Fiske 1996). Hypotheses were tested using ANOVA. Results suggested that participants who expressed more hostile sexist attitudes evaluated the gender-ambiguous applicant more negatively than a male or female applicant. In Study 2 (N?=?117), graduate and undergraduate participants were asked to indicate the gender of the ambiguous applicant. Those who scored high on hostile sexism, and perceived a gender-ambiguous applicant to be male, provided the most favorable evaluations. 相似文献
