已有大量研究揭示了近似数量系统与计算流畅性的相关关系, 但缺少对二者关系原因的系统检验与论证。视觉形状知觉假设有别于传统的数量领域特异性解释, 认为对形状的快速知觉是近似数量系统与计算流畅性的共同认知机制, 即视觉形状的快速知觉能力可以解释二者之间的相关关系。近似数量系统和计算流畅性在加工过程中依赖对形状的快速知觉, 二者在加工过程中都涉及了复杂视觉刺激的快速处理。视觉形状知觉假设得到了一系列研究结果的支持, 但局限在视觉形状知觉与二者关系的探讨上, 视觉形状知觉在二者关系中作用的加工机制仍不清楚。未来研究需要结合多种研究方法和技术, 多角度深入探讨视觉形状知觉在二者关系中作用的认知与脑机制, 并将研究结果应用于数学课堂教学和计算困难的干预中。  相似文献

This study investigated how target sex, target age, and expressive ambiguity influence emotion perception. Undergraduate participants (N = 192) watched morphed video clips of eight child and eight adult facial expressions shifting from neutral to either sadness or anger. Participants were asked to stop the video clip when they first saw an emotion appear (perceptual sensitivity) and were asked to identify the emotion that they saw (accuracy). Results indicate that female participants identified sad expressions sooner in female targets than in male targets. Participants were also more accurate identifying angry facial expressions by male children than by female children. Findings are discussed in terms of the effects of ambiguity, gender, and age on the perception of emotional expressions.  相似文献

Studies dealing with emotion regulation have known a fast expansion during the last twenty years. Yet, they are most often based on models centered on endogenous cognitive and behavioral processes as well as the pursuit of welfare, and do not consider the social aspect of emotions and emotion expression which elicit exogenous emotion regulation processes from social interaction partners. The goal of this article is to show that both endogenous and exogenous emotion regulation processes are complementary and indivisible, and to suggest working hypotheses about how they connect. In the first part of this document, after a quick reminder of the different theoretical approaches of (individual) endogenous emotion regulation, we emphasize works about social approach behaviors (social affiliation) in emotional situations. These studies report that social interactions are sometimes sought as they would allow for the endogenous implementation of interpersonal emotion regulation strategies, especially by means of emotion expression. Individual and interpersonal endogenous emotion regulation processes would then complementarily modify the emotions experienced by an individual faced with a critical situation. The second part of this article underlines that social interaction partners actually are operators of exogenous emotion regulation processes rather than passive reservoirs of resources an individual may pick up to regulate their emotions. For that purpose, we especially consider the ways relatives (directly or indirectly, explicitly or implicitly) constrain the social affiliation behaviors and emotion expressions of an individual who experiences emotions. Thus, we argue that those behaviors are strongly influenced not only by the nature and intensity of emotions, but also by: firstly, social learning about how to feel, what to express and how to regulate emotions in a specific situation; secondly, features of the social environment as well as social expectations and demands about sharing emotions versus inhibiting their expression; and thirdly, the exogenous emotion regulation strategies a partner may use to regulate an individual's emotions. This set of studies entices us to consider endogenous and exogenous emotion regulation processes as acting jointly to promote not only the adaptation to emotional situations, but also the quality of social bonds between members of a social network. Social integration is thus central in the study of emotion regulation processes.  相似文献

We examine how affect and accessible thoughts following a major natural disaster influence everyday risk perception. A survey was conducted in the months following the 2004 south Asian Tsunami in a representative sample of the Swedish population (N = 733). Respondents rated their experienced affect as well as the perceived risk and benefits of various everyday decision domains. Affect influenced risk and benefit perception in a way that could be predicted from both the affect‐congruency and affect heuristic literatures (increased risk perception and stronger risk‐benefit correlations). However, in some decision domains, self‐regulation goals primed by the natural disaster predicted risk and benefit ratings. Together, these results show that affect, accessible thoughts and motivational states influence perceptions of risks and benefits.  相似文献

The objective of this correlational study was to investigate how dispositional mindfulness is related to the experience of time as operationalized by the assessment of the time perspectives, impulsiveness, and duration judgment tasks. A sample of students (N = 63) completed self-report measures of mindfulness (FMI, CHIME), the time perspectives (ZTPI), impulsiveness (BIS), conducted psychophysical tasks of (a) auditory duration discrimination in the milliseconds range, (b) visual duration reproduction in the multiple-second range, and performed an attention task, the Attention Network Test. Being more mindful in daily life was related to less impulsiveness, better emotional handling of the past, and a more pronounced future perspective. Mindfulness was also related to more accurate timing in the milliseconds and multiple-seconds range but not to attentional control. These findings suggest a close association between dispositional mindfulness with the temporal organization of behaviour and the perception of time.  相似文献

The present functional magnetic resonance imaging study examined the neural response to familiar and unfamiliar, sport and non-sport environmental sounds in expert and novice athletes. Results revealed differential neural responses dependent on sports expertise. Experts had greater neural activation than novices in focal sensorimotor areas such as the supplementary motor area, and pre- and postcentral gyri. Novices showed greater activation than experts in widespread areas involved in perception (i.e. supramarginal, middle occipital, and calcarine gyri; precuneus; inferior and superior parietal lobules), and motor planning and processing (i.e. inferior frontal, middle frontal, and middle temporal gyri). These between-group neural differences also appeared as an expertise effect within specific conditions. Experts showed greater activation than novices during the sport familiar condition in regions responsible for auditory and motor planning, including the inferior frontal gyrus and the parietal operculum. Novices only showed greater activation than experts in the supramarginal gyrus and pons during the non-sport unfamiliar condition, and in the middle frontal gyrus during the sport unfamiliar condition. These results are consistent with the view that expert athletes are attuned to only the most familiar, highly relevant sounds and tune out unfamiliar, irrelevant sounds. Furthermore, these findings that athletes show activation in areas known to be involved in action planning when passively listening to sounds suggests that auditory perception of action can lead to the re-instantiation of neural areas involved in producing these actions, especially if someone has expertise performing the actions.  相似文献

Despite often showing behaviorally typical levels of social cognitive ability, unaffected siblings of children with autism spectrum disorder have been found to show similar functional and morphological deficits within brain regions associated with social processing. They have also been reported to show increased activation to biological motion in these same regions, such as the posterior superior temporal sulcus (pSTS), relative to both children with autism and control children. It has been suggested that this increased activation may represent a compensatory reorganization of these regions as a result of the highly heritable genetic influence of autism. However, the response patterns of unaffected siblings in the domain of action perception are unstudied, and the phenomenon of compensatory activation has not yet been replicated. The present study used functional magnetic resonance imaging to determine the neural responses to intentional biological actions in 22 siblings of children with autism and 22 matched controls. The presented actions were either congruent or incongruent with the actor’s emotional cue. Prior studies reported that typically developing children and adults, but not children with autism, show increased activation to incongruent actions (relative to congruent), within the pSTS and dorsolateral prefrontal cortex. We report that unaffected siblings did not show a compensatory response, or a preference for incongruent over congruent trials, in any brain region. Moreover, interaction analyses revealed a sub-region of the pSTS in which control children showed an incongruency preference to a significantly greater degree than siblings, which suggests a localized deficit in siblings. A sample of children with autism also did not show differential activation in the pSTS, providing further evidence that it is an area of selective disruption in children with autism and siblings. While reduced activation to both conditions was unique to the autism sample, lack of differentiation to incongruent and congruent intentional actions was common to both children with ASD and unaffected siblings.  相似文献

It is argued that causal understanding originates in experiences of acting on objects. Such experiences have consistent features that can be used as clues to causal identification and judgment. These are singular clues, meaning that they can be detected in single instances. A catalog of 14 singular clues is proposed. The clues function as heuristics for generating causal judgments under uncertainty and are a pervasive source of bias in causal judgment. More sophisticated clues such as mechanism clues and repeated interventions are derived from the 14. Research on the use of empirical information and conditional probabilities to identify causes has used scenarios in which several of the clues are present, and the use of empirical association information for causal judgment depends on the presence of singular clues. It is the singular clues and their origin that are basic to causal understanding, not multiple instance clues such as empirical association, contingency, and conditional probabilities.  相似文献
