Tourette syndrome (TS) is a neurodevelopmental disorder characterized by motor and vocal tics. Tics are repetitive and uncontrolled behaviours that have been associated with basal ganglia dysfunction. We investigated saccadic eye movements in a group of young people with TS but without co‐morbid ADHD. Participants performed two tasks. One required them to perform only pro‐saccade responses (pure pro‐saccade task). The other involved shifting, unpredictably, between executing pro‐ and anti‐saccades (mixed saccade task). We show that in the mixing saccade task, the TS group makes significantly fewer errors than an age‐matched control group, while responding equally fast. By contrast, on the pure pro‐saccade task, the TS group were shown to be significantly slower to initiate and to complete the saccades (longer movement duration and decreased peak velocity) than controls, while movement amplitude and direction accuracy were not different. These findings demonstrate enhanced shifting ability despite slower reflexive responding in TS and are discussed with respect to a disorder‐related adaptation for increased cognitive regulation of behaviour. 相似文献

Philosophers have developed three theories of luck: the probability theory, the modal theory, and the control theory. To help assess these theories, we conducted an empirical investigation of luck attributions. We created eight putative luck scenarios and framed each in either a positive or a negative light. Furthermore, we placed the critical luck event at the beginning, middle, or end of the scenario to see if the location of the event influenced luck attributions. We found that attributions of luckiness were significantly influenced by the framing of the scenario and by the location of the critical event. Positively framing an event led to significantly higher lucky ratings than negatively framing the same exact event. And the closer a negative event was placed toward the end of a scenario, the more unlucky the event was rated. Overall, our results raise the possibility that there is no such thing as luck and thereby pose serious challenges to the three prominent theories of luck. We instead propose that luck may be a cognitive illusion, a mere narrative device used to frame stories of success or failure. 相似文献

Reformed epistemology, roughly, is the thesis that religious belief can be rational without argument. After providing some background, I present Plantinga's defense of reformed epistemology and its influence on religious debunking arguments. I then discuss three objections to Plantinga's arguments that arise from the following topics: skeptical theism, cognitive science of religion, and basicality. I then show how reformed epistemology has recently been undergirded by a number of epistemological theories, including phenomenal conservatism and virtue epistemology. I end by noting that a good objection to reformed epistemology must criticize either a substantive epistemological theory or the application of that theory to religious belief; I also show that the famous Great Pumpkin Objection is an example of the former. 相似文献

Researchers conducting psychotherapy process research aim to understand the process by which efficacious psychotherapies achieve therapeutic benefits. A key challenge in this research is how to maximise what can be learned from naturalistic longitudinal data. We provide a selective overview of research examining the process of change in cognitive therapy of depression. While the efficacy of this treatment is widely recognised, a consensus regarding how the treatment reduces depressive symptoms and provides protection from relapse and recurrence has yet to be reached. We review the current state of the research addressing the process of change in cognitive therapy, highlighting how specific methodological features can be used to better understand the process by which this treatment achieves its effects. We highlight the importance of two key challenges to making causal inferences from a process–outcome relation: (a) establishing the temporal precedence of predictors to outcome variables, and (b) evaluating whether any relations identified could be spurious. We argue that methodologically rigorous studies tend to support key claims of the model underlying cognitive therapy of depression. We conclude by considering future directions. For example, we highlight the importance of efforts to understand patient characteristics that may moderate process–outcome relations and could ultimately prove useful in tailoring treatment to best suit individual patients. 相似文献

Cognitive diagnosis models of educational test performance rely on a binary Q‐matrix that specifies the associations between individual test items and the cognitive attributes (skills) required to answer those items correctly. Current methods for fitting cognitive diagnosis models to educational test data and assigning examinees to proficiency classes are based on parametric estimation methods such as expectation maximization (EM) and Markov chain Monte Carlo (MCMC) that frequently encounter difficulties in practical applications. In response to these difficulties, non‐parametric classification techniques (cluster analysis) have been proposed as heuristic alternatives to parametric procedures. These non‐parametric classification techniques first aggregate each examinee's test item scores into a profile of attribute sum scores, which then serve as the basis for clustering examinees into proficiency classes. Like the parametric procedures, the non‐parametric classification techniques require that the Q‐matrix underlying a given test be known. Unfortunately, in practice, the Q‐matrix for most tests is not known and must be estimated to specify the associations between items and attributes, risking a misspecified Q‐matrix that may then result in the incorrect classification of examinees. This paper demonstrates that clustering examinees into proficiency classes based on their item scores rather than on their attribute sum‐score profiles does not require knowledge of the Q‐matrix, and results in a more accurate classification of examinees. 相似文献

Emotional reasoning refers to the use of subjective emotions, rather than objective evidence, to form conclusions about oneself and the world. It is a key interpretative bias in cognitive models of anxiety disorders and appears to be especially evident in individuals with anxiety disorders. However, the amenability of emotional reasoning to change during treatment has not yet been investigated. We sought to determine whether emotional reasoning tendencies change during a course of routine cognitive-behavioural therapy (CBT). Emotional reasoning tendencies were assessed in 36 individuals with a primary anxiety disorder who were seeking treatment at an outpatient clinic. Changes in anxiety and depressive symptoms as well as emotional reasoning tendencies after 12 sessions of CBT were examined in 25 individuals for whom there was complete data. Emotional reasoning tendencies were evident at pretreatment assessment. Although anxiety and depressive symptoms decreased during CBT, only one of six emotional reasoning interpretative styles (pertaining to conclusions that one is incompetent) changed significantly during the course of therapy. Attrition rates were high and there was not enough information regarding the extent to which therapy specifically focused on addressing emotional reasoning tendencies. Individuals seeking treatment for anxiety disorders appear to engage in emotional reasoning, however routine individual CBT does not appear to result in changes in emotional reasoning tendencies. 相似文献

This paper describes the development and preliminary psychometric evaluation of an instrument that measures the frequency of adaptive behaviours and cognitions related to therapeutic change during cognitive behavioural therapy (CBT), for symptoms of anxiety and depression. Two studies were conducted. In study one, 661 participants completed an online survey with 28 items targeting adaptive behaviours and cognitions. Exploratory factor analysis performed on part of the sample (n = 451) revealed that a four-factor solution ‘characterised’ the data. This led to the development of a 12-item instrument, the Frequency of Actions and Thoughts Scale (FATS). Confirmatory factor analysis was used to confirm the factor structure of the FATS using the remaining sample (n = 210), which revealed an acceptable model fit. In study two, 125 participants with clinically significant symptoms of anxiety, depression, or both were recruited to an Internet-delivered CBT (iCBT) treatment course. Participants completed the FATS and other measures throughout treatment, after treatment, and at three-month follow-up. Correlations and residual change scores of the FATS and its subscales with measures of anxiety, depression, behavioural activation, and CBT-related skills usage supported the construct validity of the FATS. A significant increase in FATS scores over treatment was also observed. The findings provide preliminary support for the psychometric properties of the FATS, which appears to have utility in research investigating mechanisms of change in CBT. 相似文献
