Although many theories of emotion hypothesise a crucial role for the self-perception of visceral activity, there has been little empirical investigation of the relationship between visceral self-perception and emotion. In this study, 52 undergraduates (19 males, 33 females) performed a heartbeat detection task and were classified as good (n=9) or poor (n=43) heartbeat detectors. Subjects were then presented with sets of two film clips, each targeting one of three different emotional valences (amusement, anger, fear). Subjects reported their affective responses to the clips on 9-point scales indicating intensity and pleasantness. Good detectors reported more intense emotions than poor detectors across all three emotional valences, but no differences were found on pleasantness ratings between the groups. These results suggest that visceral perception plays a role in the experience of the intensity of emotions. 相似文献

Decision-making research has thoroughly investigated how people choose from a set of externally provided options. However, in ill-structured real-world environments, possible options for action are not defined by the situation but have to be generated by the agent. Here, we apply behavioral analysis (Study 1) and functional magnetic resonance imaging (Study 2) to investigate option generation and subsequent choice. For this purpose, we employ a new experimental task that requires participants to generate options for simple real-world scenarios and to subsequently decide among the generated options. Correlational analysis with a cognitive test battery suggests that retrieval of options from long-term memory is a relevant process during option generation. The results of the fMRI study demonstrate that option generation in simple real-world scenarios recruits the anterior prefrontal cortex. Furthermore, we show that choice behavior and its neural correlates differ between self-generated and externally provided options. Specifically, choice between self-generated options is associated with stronger recruitment of the dorsal anterior cingulate cortex. This impact of option generation on subsequent choice underlines the need for an expanded model of decision making to accommodate choice between self-generated options. 相似文献

Abstract Surgery can be regarded as a major stressor for any patient. High preoperative emotional arousal may negatively influence adjustment during surgery as well as the postoperative recovery rate. Consequently, the strategies individuals employ for coping with this stress are of prime importance for the quality of their adaptation. This paper reports the construction and empirical assessment of a new instrument for measuring strategies employed to cope with surgical stress. Factor analysis of this instrument, the Coping with Surgical Stress Scale (COSS), yielded five factors: Rumination, Optimism and Trust, Turning to Social and Religious Resources, Threat Avoidance, and Information Seeking. Internal consistencies of the corresponding subscales were satisfactory. Results concerning external relationships of the COSS with dispositional coping, state and trait anxiety, and indicators of perioperative adjustment showed that the COSS is a useful instrument for measuring surgery-related coping. 相似文献

Cognitive behavioral therapy is an effective treatment for virtually all psychiatric disorders. However, very few patients have access to it and few therapists are trained in the theory and practice of cognitive behavioral therapy. Based on the existing evidence and the articles of this series, the following recommendations are made: (a) all mental health care providers (including Psy.D. and social workers) need to be trained in the practice and theories of empirically supported treatments, specifically cognitive behavioral therapy; (b) clinical practice also needs to be based on theory, not just treatment manuals; and (c) psychological treatments have to move beyond the DSM boundaries. 相似文献

Recent research suggests synesthesia as a result of a hypersensitive multimodal binding mechanism. To address the question whether multimodal integration is altered in synesthetes in general, grapheme‐colour and auditory‐visual synesthetes were investigated using speech‐related stimulation in two behavioural experiments. First, we used the McGurk illusion to test the strength and number of illusory perceptions in synesthesia. In a second step, we analysed the gain in speech perception coming from seen articulatory movements under acoustically noisy conditions. We used disyllabic nouns as stimulation and varied signal‐to‐noise ratio of the auditory stream presented concurrently to a matching video of the speaker. We hypothesized that if synesthesia is due to a general hyperbinding mechanism this group of subjects should be more susceptible to McGurk illusions and profit more from the visual information during audiovisual speech perception. The results indicate that there are differences between synesthetes and controls concerning multisensory integration – but in the opposite direction as hypothesized. Synesthetes showed a reduced number of illusions and had a reduced gain in comprehension by viewing matching articulatory movements in comparison to control subjects. Our results indicate that rather than having a hypersensitive binding mechanism, synesthetes show weaker integration of vision and audition. 相似文献

Can sexist behavior in a job application context threaten women and cause them to underperform on a subsequent cognitive ability test? In a simulated job interview, 46 women and 46 men -- undergraduate and graduate students from the University of Heidelberg, Germany -- were confronted with either sexist (dominant and physically close) behavior by a male interviewer or non-sexist (friendly and neutral) behavior by the same confederate. Participants then solved math items and language-related items from a German standard intelligence test. In accordance with our hypothesis, the results indicated that female participants in the sexist condition performed significantly worse on the mathematical test than female participants in the control condition. The performance of female participants on the language-related test and male participants on both the math and language-related tests did not differ by experimental condition. After the sexist job interview, women’s impaired performance, occurring on the math items only (i.e., specific to the domain in which women are negatively stereotyped), suggests an influence of psychological and interpersonal processes on seemingly objective test outcomes. 相似文献

Learning and memory processes critically involve the orchestrated regulation of de novo protein synthesis. On the other hand it has become clear that regulated protein degradation also plays a major role in neuronal plasticity and learning behavior. One of the key pathways mediating protein degradation is proteosomal protein destruction. The anaphase-promoting complex/cyclosome (APC/C) is an E3 ubiquitin ligase that targets proteins for proteosomal degradation by the 26S proteasome. While the APC/C is essential for cell cycle progression it is also expressed in postmitotic neurons where it has been implicated with axonal outgrowth and neuronal survival. In this study we addressed the role of APC/C in learning and memory function by generating mice that lack the essential subunit APC2 from excitatory neurons of the adult forebrain. Those animals are viable but exhibit a severe impairment in the ability to extinct fear memories, a process critical for the treatment of anxiety diseases such as phobia or post-traumatic stress disorder. Since deregulated protein degradation and APC/C activity has been implicated with neurodegeneration we also analyzed the effect of Apc2 deletion in a mouse model for Alzheimer's disease. In our experimental setting loss of APC2 form principle forebrain neurons did not affect the course of pathology in an Alzheimer's disease mouse model. In conclusion, our data provides genetic evidence that APC/C activity in the adult forebrain is required for cognitive function. 相似文献

The Bruce and Young (1986) framework makes a number of important distinctions between the types of representation needed to recognize a familiar face. Here, we return to these, focussing particularly on face recognition units. We argue that such representations need to incorporate idiosyncratic within-person variability, asking questions such as 'What counts as a picture of Harrison Ford?'. We describe a mechanism for achieving this, and discuss the relation between image variability and episodic face memories, in the context of behavioural and neurophysiological data. 相似文献
