Theories concerning the structure, or format, of mental representation should (1) be formulated in mechanistic, rather than metaphorical terms; (2) do justice to several philosophical intuitions about mental representation; and (3) explain the human capacity to predict the consequences of worldly alterations (i.e., to think before we act). The hypothesis that thinking involves the application of syntax‐sensitive inference rules to syntactically structured mental representations has been said to satisfy all three conditions. An alternative hypothesis is that thinking requires the construction and manipulation of the cognitive equivalent of scale models. A reading of this hypothesis is provided that satisfies condition (1) and which, even though it may not fully satisfy condition (2), turns out (in light of the frame problem) to be the only known way to satisfy condition (3). 相似文献

Determining response or remission status in body dysmorphic disorder (BDD) usually requires a lengthy interview with a trained clinician. This study sought to establish empirically derived cutoffs to define treatment response and remission in BDD using a brief self-report instrument, the Appearance Anxiety Inventory (AAI). Results from three clinical trials of BDD were pooled to create a sample of 123 individuals who had received cognitive-behavioral therapy for BDD, delivered via the Internet. The AAI was compared to gold-standard criteria for response and remission in BDD, based on the clinician-administered Yale–Brown Obsessive Compulsive Scale, modified for BDD (BDD-YBOCS), and evaluated using signal detection analysis. The results showed that a ≥ 40% reduction on the AAI best corresponded to treatment response, with a sensitivity of 0.71 and a specificity of 0.84. A score ≤ 13 at posttreatment was the optimal cutoff in determining full or partial remission from BDD, with a sensitivity of 0.75 and a specificity of 0.88. These findings provide benchmarks for using the AAI in BDD treatment evaluation when resource-intensive measures administered by clinicians are not feasible. 相似文献

ObjectivesThe term “clutch” is colloquially used to describe important or crucial situations in sport, with clutch performance referring to successful performances during these pressurised circumstances. Positioning the clutch as an objective, situational variable, however, may not account for the athletes' subjective appraisal of such situations. Accordingly, this study aimed to explore athletes' perceptions of clutch situations, and further, how these perceptions influenced their performance.MethodSixteen athletes (Mage = 26.88 years) participated in event-focused, semi-structured interviews soon after a clutch performance (M = 4 days later). Data were analysed utilising reflexive thematic analysis.ResultsFour themes were generated: (1) the clutch involves situational and subjective factors, suggesting that the appraisal of the clutch is influenced by situational and subjective components; (2) the perception of the clutch comes and goes, suggesting that there may be multiple, fluctuating episodes of the clutch within an event; (3) pressure affects performance, and performance affects pressure, suggesting that the appraisal of pressure was perceived to impact performance, and that performance also influenced appraisal of pressure; and, (4) experience of anxiety during the clutch is varied, suggesting that the experience of anxiety is not inherent to clutch performance.ConclusionsThe clutch has traditionally been considered an objective, situational variable. This study suggests, however, that the clutch relies upon the athlete appraising pressure in response to these situational variables, which may not always occur. Further, other subjective factors may increase the appraisal of pressure, suggesting that the clutch cannot solely be considered as a situational variable. 相似文献

It has been proposed that one means of understanding a person's current behaviour and predicting future actions is by simulating their actions. That is, when another person's actions are observed, similar motor processes are activated in the observer. For example, after observing a reach over an obstacle, a person's subsequent reach trajectory is more curved, reflecting motor priming. Importantly, such motor states are only activated if the observed action is in near (peripersonal) space. However, we demonstrate that when individuals share action environments, simulation of another person's obstacle avoiding reach path takes place even when the action is in far (extrapersonal) space. We propose that action simulation is influenced by factors such as ownership. When an “owned” object is a potential future obstacle, even when it is viewed beyond current action space, simulations are evoked, and these leave a more stable memory capable of influencing future behaviour. 相似文献

Theory of Mind (ToM) is the ability to infer other people’s mental states like
intentions or desires. ToM can be differentiated into affective (i.e.,
recognizing the feelings of another person) and cognitive (i.e., inferring the
mental state of the counterpart) subcomponents. Recently, subcortical structures
such as the basal ganglia (BG) have also been ascribed to the multifaceted
concept ToM and most BG disorders have been reported to elicit ToM deficits. In
order to assess both the correlates of affective and cognitive ToM as well as
involvement of the basal ganglia, 30 healthy participants underwent
event-related fMRI scanning, neuropsychological testing, and filled in
questionnaires concerning different aspects of ToM and empathy. Directly
contrasting affective (aff) as well as cognitive (cog) ToM to the control (phy)
condition, activation was found in classical ToM regions, namely parts of the
temporal lobe including the superior temporal sulcus, the supplementary motor
area, and parietal structures in the right hemisphere. The contrast aff > phy
yielded additional activation in the orbitofrontal cortex on the right and the
cingulate cortex, the precentral and inferior frontal gyrus and the cerebellum
on the left. The right BG were recruited in this contrast as well. The direct
contrast aff > cog showed activation in the temporoparietal junction and the
cingulate cortex on the right as well as in the left supplementary motor area.
The reverse contrast cog > aff however did not yield any significant clusters.
In summary, affective and cognitive ToM partly share neural correlates but can
also be differentiated anatomically. Furthermore, the BG are involved in
affective ToM and thus their contribution is discussed as possibly providing a
motor component of simulation processes, particularly in affective ToM. 相似文献

With reference to Henderson's (2004) assumption that inventors are “expert problem solvers”, we studied the ability of inventors to solve complex problems (CPS) using a sample of 46 German inventors. The participants had to use FSYS 2.0, a computer-simulated microworld. Additionally, we assessed metacognition, in particular the participants' ability to make deliberate use of divergent and convergent thinking. This ability was expected to be an important skill involved in solving complex problems (Dörner, Kreuzig, Reither, & Stäudel, 1983). We assumed a positive correlation between the individual success of inventors (number of granted and marketed patents) and CPS abilities. Controllability of divergent and convergent thinking turned out to be a predictor of the success of inventors and allowed us to identify the top 10% performers. Oddly however, the best problem solvers were inventors with exactly one granted patent. Data from a posteriori conducted interviews help explaining the results. 相似文献

How Do Propensity Score Methods Measure Up in the Presence of Measurement Error? A Monte Carlo Study
Patricia Rodríguez De Gil Aarti P. Bellara Rheta E. Lanehart Reginald S. Lee Eun Sook Kim 《Multivariate behavioral research》2013,48(5):520-532
Considering that the absence of measurement error in research is a rare phenomenon and its effects can be dramatic, we examine the impact of measurement error on propensity score (PS) analysis used to minimize selection bias in behavioral and social observational studies. A Monte Carlo study was conducted to explore the effects of measurement error on the treatment effect and balance estimates in PS analysis across seven different PS conditioning methods. In general, the results indicate that even low levels of measurement error in the covariates lead to substantial bias in estimates of treatment effects and concomitant reduction in confidence interval coverage across all methods of conditioning on the PS. 相似文献
