Functional magnetic resonance imaging (fMRI) was used to assess neural activation as participants learned to segment continuous streams of speech containing syllable sequences varying in their transitional probabilities. Speech streams were presented in four runs, each followed by a behavioral test to measure the extent of learning over time. Behavioral performance indicated that participants could discriminate statistically coherent sequences (words) from less coherent sequences (partwords). Individual rates of learning, defined as the difference in ratings for words and partwords, were used as predictors of neural activation to ask which brain areas showed activity associated with these measures. Results showed significant activity in the pars opercularis and pars triangularis regions of the left inferior frontal gyrus (LIFG). The relationship between these findings and prior work on the neural basis of statistical learning is discussed, and parallels to the frontal/subcortical network involved in other forms of implicit sequence learning are considered. 相似文献

AbstractObjective: Because the working memory (WM) has a limited capacity, the cognitive reactions towards persuasive information in the WM might be disturbed by taxing it by other means, in this study, by inducing voluntary eye movements (EMi). This is expected to influence persuasion.Methods: Participants (N?=?127) listened to an auditory persuasive message on fruit and vegetable consumption, that was either framed positively or negatively. Half of them was asked to keep following a regularly moving dot on their screen with their eyes. At pretest, cognitive self-affirmation inclination (CSAI) was assessed as individual difference to test possible moderation effects.Results: The EMi significantly lowered the quality of the mental images that participants reported to have of the persuasive outcomes. With regard to self-reported fruit and vegetable consumption after two weeks, EMi significantly lowered consumption when CSAI was high but it significantly increased consumption when CSAI was low.Conclusions: The results verify our earlier findings that induced EM can influence persuasion. Although it remains unclear whether the effects of EMi were caused by disturbing mental images of persuasive outcomes or self-regulative reactions to these images, or both, the WM account may provide new theoretical as well as practical angles on persuasion. 相似文献

The negative effect of cross‐examination‐style questioning on children's accuracy is likely to be due to the complex and credibility‐challenging questions that characterize the interview. Given that cross‐examination occurs after at least one prior interview, however, it is equally possible that repeated interviewing per se impairs children's accuracy, and that the questions asked have little bearing on children's responses. To examine this issue, 5‐ and 6‐year‐old children (n= 82) and 9‐ and 10‐year‐old children (n= 103) took part in a surprise event and were then interviewed using an analogue of direct examination. Either 1 week or 6 months later, half of the children were re‐interviewed with an analogue of cross‐examination designed to challenge their direct examination responses. Remaining children were re‐interviewed with the same questions that were asked during direct examination. Children's accuracy decreased following their second interview, irrespective of age or delay; however, delay particularly impacted younger children's second interview performance. Children's accuracy was most impaired following a cross‐examination‐style interview. Overall, cross‐examination‐style questioning appears to be particularly detrimental to obtaining accurate event reports from children. 相似文献

Abstract This pilot study tested the efficacy of the My Disaster Recovery (MDR) website to decrease negative affect and increase coping self-efficacy. Fifty-six survivors of Hurricane Ike were recruited from a larger study being conducted at the University of Texas Medical Branch at the first anniversary of the storm. Restricted randomization was used to assign participants to the MDR website, an information-only website, or a usual care condition. Group×time interactions indicated that MDR reduced participant worry more than the other conditions. A similar trend was also identified for depression. Both websites were accessed a small to moderate amount and participants reported mixed satisfaction for both websites. Although the effect sizes for worry and depression were in the moderate to large range, small sample size and timing of the intervention qualify the findings. These preliminary findings encourage further evaluation of MDR with a larger, demographically diverse sample and indicate that the MDR website might be helpful in reducing worry and depression. 相似文献

This article presents a repertory grid study of young people who had experienced civil war in Sierra Leone, some as child soldiers and others as noncombatants. Unexpected findings included that the former combatants viewed themselves more favorably than did noncombatants. The findings are discussed in terms of individual and social construing processes, drawing on narratives and interview and focus group responses obtained from the participants in the larger investigation of which this study was part. Particular consideration is given to the role of forgiveness. 相似文献

One barrier to widespread public access to empirically supported treatments (ESTs) is the limited availability and high cost of professionals trained to deliver them. Our earlier work from 2 clinical trials demonstrated that front-line addiction counselors could be trained to deliver a manualized, group-based cognitive behavioral therapy (GCBT) for depression, a prototypic example of an EST, with a high level of adherence and competence. This follow-up article provides specific recommendations for the selection and initial training of counselors, and for the structure and process of their ongoing clinical supervision. We highlight unique challenges in working with counselors unaccustomed to traditional clinical supervision. The recommendations are based on comprehensive feedback derived from clinician notes taken throughout the clinical trials, a focus group with counselors conducted 1 year following implementation, and interviews with key organization executives and administrators. 相似文献

This study investigated whether childhood physical abuse was associated with functional somatic syndromes (FSS) in women while controlling for age, race, and four clusters of potentially confounding factors: (a) Other childhood adversities, (b) adult health behaviors, (c) socioeconomic status and stressors, and (d) mental health. A regional subsample of the 2005 Canadian Community Health Survey of 7,342 women was used. Women reported whether they had been diagnosed with chronic fatigue syndrome (CFS), fibromyalgia (Fm), irritable bowel syndrome (IBS), or multiple chemical sensitivities (MCS). Fully 749 reported having been physically abused by someone close to them during their youth. When controlling for potentially confounding factors, childhood physical abuse was significantly associated with CFS (OR = 2.11; 95% CI = 1.22, 3.65), Fm (OR = 1.65; 95% CI = 1.08, 2.52), and MCS (OR = 2.82; 95% = CI 1.90, 4.17). Clinicians using reattribution and stepped care approaches in the management of FSS should assess for a history of abuse. 相似文献

Object drawing can be supported by a number of cognitive resources, each making available visual information about the object being drawn. These resources include perceptual input, short-term visual memory, and long-term visual memory. Each of these resources has the potential to make available distinct forms of visual representation, including viewpoint-specific and viewpoint-independent representations, object-specific and category representations, and separate representations of object colour. We review neuropsychological and developmental evidence supporting these claims, including evidence that the same drawing can reflect the influence of multiple forms of visual representation. Seven experiments are then reported, investigating object drawing by 4- to 6-year-old children, to confirm the support for drawing provided by different forms of visual representation. Young children are selected for investigation because their drawing is relatively unconstrained by culturally determined norms which, in our culture, dictate that objects should be drawn just as they appear from the vantage point of the drawer. To distinguish the support provided by object and category representations, the experiments exploit the privileged links between count nouns as object labels, and representations of object categories. In addition, pre-established representations, visual or otherwise, are precluded from influencing drawing by asking the children to draw novel objects, and by creating novel count nouns with which to label the objects. The results reveal how viewpoint-specific perceptual representations, object-specific representations of shape and of colour, and category representations of shape can each impact on object drawing, and in some circumstances on the same drawing. It appears that simple drawing tasks have the potential to reveal some of the distinct types of representation able to support visual cognition. 相似文献

In three experiments, we investigated transsaccadic object file representations. In each experiment, participants moved their eyes from a central fixation cross to a saccade target located between two peripheral objects. During the saccade, this preview display was replaced with a target display containing a single object to be named. On trials in which the target identity matched one of the preview objects, its colour either matched or did not match the previewed object colour. The results indicated that colour changes disrupt perceptual continuity, but only for the class of objects for which colour is diagnostic of object identity. When the colour is not integral to identifying an object (for example, when the object is a letter or an object without a characteristic colour), object continuity is preserved regardless of changes to the object's colour. These results suggest that object features that are important for defining the object are incorporated into its episodic representation. Furthermore, the results are consistent with previous work showing that the quality of a feature's representation determines its importance in preserving continuity. 相似文献

The performance of 93 children aged 3 and 4 years on a battery of different counterfactual tasks was assessed. Three measures: short causal chains, location change counterfactual conditionals, and false syllogisms—but not a fourth, long causal chains—were correlated, even after controlling for age and receptive vocabulary. Children's performance on our counterfactual thinking measure was predicted by receptive vocabulary ability and inhibitory control. The role that domain general executive functions may play in 3- to 4-year olds' counterfactual thinking development is discussed. 相似文献
