Tourette syndrome (TS) is a neuro‐developmental disorder characterized by the occurrence of motor and vocal tics: involuntary, repetitive, stereotyped behaviours that occur with a limited duration, often typically many times in a single day. Previous studies suggest that children and adolescents with TS may undergo compensatory, neuroplastic changes in brain structure and function that help them gain control over their tics. In the current study we used single‐pulse and dual‐site paired‐pulse transcranial magnetic stimulation (TMS), in conjunction with a manual choice reaction time task that induces high levels of inter‐manual conflict, to investigate this conjecture in a group of children and adolescents with TS, but without co‐morbid Attention Deficit Hyperactivity Disorder (ADHD). We found that performance on the behavioural response‐conflict task did not differ between the adolescents with TS and a group of age‐matched typically developing individuals. By contrast, our study demonstrated that cortical excitability, as measured by TMS‐induced motor‐evoked potentials (MEPs), was significantly reduced in the TS group in the period immediately preceding a finger movement. This effect is interpreted as consistent with previous suggestions that the cortical hyper‐excitability that may give rise to tics in TS is actively suppressed by cognitive control mechanisms. Finally, we found no reliable evidence for altered patterns of functional inter‐hemispheric connectivity in TS. These results provide evidence for compensatory brain reorganization that may underlie the increased self‐regulation mechanisms that have been hypothesized to bring about the control of tics during adolescence. 相似文献

The location negative priming (NP) effect refers to the fact that the processing of a current target stimulus (probe trial) is delayed when it appears at a location that has recently contained a distractor event (prime trial), relative to when it occurs at a previously unoccupied position. One view is that the process causing the NP effect involves the inhibition of the internal representation of the prime-distractor event, and that the future processing of target stimuli that involve this event are prolonged because this distractor inhibition is persistent. In this study, we examined the possibility that the NP process (inhibition) could act proactively; specifically asking whether inhibition could be allocated to a location merely predicted to hold a future distractor event. To do this, we cued the probe distractor's location using an otherwise traditional location NP paradigm. No evidence of a proactive NP process was obtained. Probe-trial target latency was the same whether it appeared at the cued distractor location or at a new location, but was delayed when it occupied the prime-distractor location (NP effect). The location NP process is seemingly a reactive one, applying inhibition only when an actual distractor is present, much as past theories have implied. 相似文献

Seventy-one children in three groups (reading disabilities, ADHD without reading disabilities, and normal controls) were compared on their ability to rapidly name colors, letters, numbers, and objects (RAN Tasks) and alternating letters/numbers and letters/numbers/colors (RAS tasks). Children with reading disabilities were found to be slower on letter- and number-naming tasks and made more errors on all tasks than controls or children with ADHD. There was an age effect for the RAN/RAS tasks, with younger children with reading disabilities performing more poorly on all tasks, while the older children with reading disabilities showed poorer performance only on the letter- and number-naming tasks. 相似文献

In recent years, facial difference is increasingly on the public and academic agenda. This is evidenced by the growing public presence of individuals with an atypical face, and the simultaneous emergence of research investigating the issues associated with facial variance. The scholarship on facial difference approaches this topic either through a medical and rehabilitation perspective, or a psycho-social one. However, having a different face also encompasses an embodied dimension. In this paper, we explore this embodied dimension by interpreting the stories of individuals with facial limb absence against the background of phenomenological theories of the body, illness and disability. Our findings suggest that the atypical face disrupts these individuals’ engagement with everyday projects when it gives rise to disruptive perceptions, sensations, and observations. The face then ceases to be the absent background to perception, and becomes foregrounded in awareness. The disruptions evoked by facial difference call for adjustments: as they come to terms with their altered face, the participants in our study gradually develop various new bodily habits that re-establish their face’s absence, or relate to its disruptive presence. It is through these emergent habits that facial difference comes to be embodied. By analyzing the everyday experiences of individuals with facial limb absence, this article provides a much-needed exploration of the embodied aspects of facial difference. It also exemplifies how a phenomenological account of illness and disability can do justice both to the impairments and appearance issues associated with atypical embodiment. 相似文献

The aim of this randomized controlled trial was to evaluate the efficacy of an evidence-based parenting program (the Triple P-Positive Parenting Program), intending to improve parenting skills and children's well-being. Parents participating in a Group Triple P program (n=50 couples) were compared with parents of a non-treated control group (n=50 couples) and parents participating in a marital distress prevention program (couples coping enhancement training (CCET)) (n=50 couples). The two major goals of this study were (a) to evaluate the efficacy of Triple P compared with the two other treatment conditions over a time-span of 1 year and (b) to answer the question whether this program that was developed in Australia is culturally accepted by Swiss parents. Results revealed that Triple P was effective with Swiss families. Mothers of the Triple P group showed significant improvements in parenting, parenting self-esteem, and a decrease in stressors related to parenting. Women trained in Triple P also reported significantly lower rates of child's misbehavior than women of the two other conditions. However, in men only a few significant results were found. Positive effects of the relationship training (CCET) were somewhat lower than those for the Triple P. These findings are further discussed. 相似文献

We elaborate on the approach to syllogistic reasoning based on “case identification” (Stenning & Oberlander, 1995; Stenning & Yule, 1997). It is shown that this can be viewed as the formalisation of a method of proof that dates back to Aristotle, namely proof by exposition (ecthesis), and that there are traces of this method in the strategies described by a number of psychologists, from Störring (1908) to the present day. We hypothesised that by rendering individual cases explicit in the premises, the chance that reasoners would engage in a proof by exposition would be enhanced, and thus performance improved. To do so, we used syllogisms with singular premises (e.g., this X is Y). This resulted in a uniform increase in performance as compared to performance on the associated standard syllogisms. These results cannot be explained by the main theories of syllogistic reasoning in their current state. 相似文献

This study examined how comprehension-based silent reading rate (CBSRR) is affected by grade, genre, and text position. Second and fourth graders read 2 grade-specific passages (one narrative, one informational) in 4 sections, each followed by 4 comprehension questions. Analyses of rate with a criterion level of comprehension showed higher performances on informational than narrative texts and better performances as students moved through sections of a text. Percentages of students attaining CBSRR decreased across the four sections of both genres and at both grade levels. Implications of findings are discussed and question are raised about text complexity and silent reading patterns. 相似文献

The examination of blood flow velocity (BFV) changes during the performance of mental tasks is one of the applications of transcranial Doppler (TCD) ultrasonography. The purpose of this review is to summarize the results of the functional TCD literature, to investigate the effects of methodological differences between studies, and to provide guidelines for future research. It is concluded that larger series of more homogeneous groups concerning age and handedness, and stricter criteria for subject selection and laboratory setting are required. The implication of quantitative and qualitative performance measures and psychological parameters (motivation, anxiety, and task anticipation) could also yield important information. We recommend future agreement upon a more standardized methodology. TCD promises to be a useful tool to provide further insight into the cerebral organization and temporal reactivity of the human brain. 相似文献

The correspondence between the Hare Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995) and the Hare Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991, 2003) was examined in forensic (N = 175) and correctional (N = 188) samples. Intermeasure correlations for Total scores (.95 forensic, .94 correctional) and the original 2-factor, D. J. Cooke and C. Michie's (2001) 3-factor, and R. D. Hare's (2003) 4-facet models (range = .87-.95) were high. Area under the curve values for the PCL:SV were .98 in both samples (cutoff = PCL-R Total score of 25). The PCL:SV performed well as a screen, maximizing false positive relative to false negative errors. Close correlations for prediction of violent recidivism in the correctional sample were obtained for the PCL-R (.42) and PCL:SV (.37). Results indicate the robust relation between the measures is maintained whether they are completed on the basis of file review only or file plus interview and whether the same or different raters score the measures. 相似文献
