Children with Attention-Deficit/Hyperactivity Disorder (ADHD) are thought to have fundamental deficits in the allocation of attention for information processing. Furthermore, it is believed that these children possess a fundamental difficulty in motoric timing, an assertion that has been explored recently in adults and children. In the present study we extend this recent work by fully exploring the classic Wing and Kristofferson (1973) analysis of timing with typically developing children (n=24) and children with ADHD (n=27). We provide clear evidence that not only do children with ADHD have an overall timing deficit, they also time less consistently when using a similar strategy to typically developing children. The use of the Wing and Kristofferson approach to timing, we argue, will result in the discovery of robust ADHD-related timing differences across a variety of situations. 相似文献

Mood affects social cognition and "theory of mind", such that people in a persistent negative mood (i.e., dysphoria) have enhanced abilities at making subtle judgements about others' mental states. Theorists have argued that this hypersensitivity to subtle social cues may have adaptive significance in terms of solving interpersonal problems and/or minimising social risk. We tested whether increasing the social salience of a theory of mind task would preferentially increase dyspshoric individuals' performance on the task. Forty-four dysphoric and 51 non-dysphoric undergraduate women participated in a theory of mind decoding task following one of three motivational manipulations: (i) social motivation (ii) monetary motivation, or (iii) no motivation. Social motivation was associated with the greatest accuracy of mental state decoding for the dysphoric group, whereas the non-dysphoric group showed the highest accuracy in the monetary motivation condition. These results suggest that dysphoric individuals may be especially, and preferentially, motivated to understand the mental states of others. 相似文献

Trait anxiety is a characteristic predisposition to appraise stimuli as threatening and respond with anxiety. Trait anxiety is proposed to serve as a vulnerability factor for greater frequency and intensity of anxiety experiences as well as the development of anxious pathology. Cognitive, behavioral, and physiological components of trait anxiety have been described. Common self-report measures of trait anxiety are reviewed with an emphasis on: components assessed, factor structure, internal consistency, reliability, and construct validity. Measures were selected if instructions ask individuals to endorse items based on their characteristic, rather than a time sensitive, response. Selection criteria resulted in a focus on the following measures: the State-Trait Anxiety Inventory (STAI), Beck Anxiety Inventory-Trait (BAIT), Cognitive Somatic Anxiety Questionnaire (CSAQ), Endler Multidimensional Anxiety Scales-Trait (EMAS-T), Four Systems Anxiety Questionnaire (FSAQ), State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA), and the Three Systems Anxiety Questionnaire (TSAQ). While the STAI has the advantage of normative data and frequent use in prior research, newer measures, such as the BAIT and the STICSA, demonstrate greater discriminant validity. The strengths and weaknesses of each of the reviewed measures are highlighted. Recommendations for measure selection and future research are provided. 相似文献

It has previously been shown that when picture pairs are repeated across blocks in a post-cue naming task, former distractors are named faster than former targets: the “negative repetition effect” (Mayall, Humphreys, & Kotsanis, 2002). In the present study the time course of this effect was examined. Experiment 1 demonstrated that the effect became apparent after a lag of only two intervening trials, with former targets being named faster than former distractors after a lag of zero trials. Experiment 2 used a new baseline condition with repeated picture pairs for which no response was required on the first presentation. Comparisons with this baseline indicated that the negative repetition effect is the result of suppression of former targets as opposed to facilitation of former distractors. The results support the proposal of Mayall et al. that the negative repetition effect reflects a form of speech monitoring that is applied when there is competition in the process of mapping from semantics to name representations. 相似文献
