Time perception, crucial for adaptive behavior, has been shown to be altered by emotion. An arousal-dependent mechanism is proposed to account for such an effect. Yet, physiological measure of arousal related with emotional timing is still lacking. We addressed this question using skin conductance response (SCR) in an emotion regulation paradigm. Nineteen participants estimated durations of neutral and negative sounds by comparing them to a previously memorized duration. Instructions were given to attend either to temporal or to emotional stimulus features. Attending to emotion with negative sounds generated longer subjective duration and greater physiological arousal than attending to time. However, a shared-attention condition showed discrepancy between behavioral and physiological results. Supporting the idea of a link between autonomic arousal and subjective duration, our results however suggest that this relation is not as direct as was expected. Results are discussed within recent model linking time perception, emotion and awareness. 相似文献

Although adequate emotion regulation is considered to be essential in every day life, it is especially important in social interactions. However, the question as to what extent two different regulation strategies are effective in changing decision-making in a consequential socially interactive context remains unanswered. We investigated the effect of expressive suppression and emotional reappraisal on strategic decision-making in a social interactive task, that is, the Ultimatum Game. As hypothesized, participants in the emotional reappraisal condition accepted unfair offers more often than participants in the suppression and no-regulation condition. Additionally, the effect of emotional reappraisal influenced the amount of money participants proposed during a second interaction with partners that had treated them unfairly in a previous interaction. These results support and extend previous findings that emotional reappraisal as compared to expressive suppression, is a powerful regulation strategy that influences and changes how we interact with others even in the face of inequity. 相似文献

The present study examined the relationship between unilateral brain damage and the effect of nonverbal perceptual priming using a picture-fragment completion task. Subjects consisted of 11 left brain-damaged patients, 8 right brain-damaged patients, and 10 healthy normal controls. The mean score of normal controls was significantly higher than those of left and right brain-damaged patients. Although there were significant effects of priming in all the groups, a significant difference in amplitude of priming effects was found only between right brain-damaged patients and normal controls. The correlation between amount of fragmentation at which there was identification and priming effect was not significant. We conclude that the right hemisphere is more involved in perceptual priming of form than is the left hemisphere, and form-dependent processing in the perceptual priming task has an asymmetrical distribution in the right and left hemispheres. 相似文献

The role of social cognition in emotion 总被引:3,自引:0,他引:3
Although recent research has shown that social cognition and emotion engage overlapping regions of the brain, few accounts of this overlap have been offered. What systems might be commonly or distinctively involved in each? The close functional relationship between social cognition and emotion might be understood in terms of a central role for mental state attribution in the understanding, learning and regulation of emotion. In each of these cases, mental state attributions might be supported by either stimulus-driven or more reflective processes. 相似文献

A sample (n=48) of eight-year-olds with specific language impairments is compared with age-matched (n=55) and language matched controls (n=55) on a range of tasks designed to test the interdependence of language and mathematical development. Performance across tasks varies substantially in the SLI group, showing profound deficits in production of the count word sequence and basic calculation and significant deficits in understanding of the place-value principle in Hindu-Arabic notation. Only in understanding of arithmetic principles does SLI performance approximate that of age-matched-controls, indicating that principled understanding can develop even where number sequence production and other aspects of number processing are severely compromised. 相似文献

This study used a sample of 154 cabin attendants to examine the role of self-efficacy in the performance of emotion work. On the basis of the literature, we hypothesized that self-efficacy would have a moderating influence on the relationship between emotional job demands (i.e., feeling rules and emotionally charged interactions with passengers) and emotional dissonance, and on the relationship between emotional dissonance and well-being (emotional exhaustion and work engagement). In addition, we predicted that emotional dissonance mediates the relationship between emotional job demands and well-being. The results of a series of hierarchical multiple regression analyses generally supported these hypotheses. Results confirmed that emotionally charged interactions with passengers are related to emotional exhaustion and engagement through their influence on emotional dissonance. Furthermore, self-efficacy buffers the relationship between emotional job demands and emotional dissonance, and the relationship between emotional dissonance and work engagement (but not exhaustion). 相似文献

In contextual cueing, the position of a search target is learned over repeated exposures to a visual display. The strength of this effect varies across stimulus types. For example, real-world scene contexts give rise to larger search benefits than contexts composed of letters or shapes. We investigated whether such differences in learning can be at least partially explained by the degree of semantic meaning associated with a context independently of the nature of the visual information available (which also varies across stimulus types). Chess boards served as the learning context as their meaningfulness depends on the observer's knowledge of the game. In Experiment 1, boards depicted actual game play, and search benefits for repeated boards were 4 times greater for experts than for novices. In Experiment 2, search benefits among experts were halved when less meaningful randomly generated boards were used. Thus, stimulus meaningfulness independently contributes to learning context-target associations. 相似文献

Three experiments evaluated whether facial expression can modulate the allocation of focused attention. Identification of emotionally expressive target faces was typically faster when they were flanked by identical (compatible) faces compared with when they were flanked by different (incompatible) faces. This flanker compatibility effect was significantly smaller when target faces expressed negative compared with positive emotion (see Experiment 1A); however, when the faces were altered to disrupt emotional expression, yet retain feature differences, equal flanker compatibility effects were observed (see Experiment 1B). The flanker-compatibility effect was also found to be smaller for negative target faces compared compatibility with neutral target faces, and for both negative and neutral target faces compared with positive target faces (see Experiment 2). These results suggest that the constriction of attention is influenced by facial expressions of emotion. 相似文献

The perceptual restoration of musical sounds was investigated in 5 experiments with Samuel's (1981a) discrimination methodology. Restoration in familiar melodies was compared to phonemic restoration in Experiment 1. In the remaining experiments, we examined the effect of expectations (generated by familiarity, predictability, and musical schemata) on musical restoration. We investigated restoration in melodies by comparing familiar and unfamiliar melodies (Experiment 2), as well as unfamiliar melodies varying in tonal and rhythmic predictability (Experiment 3). Expectations based on both familiarity and predictability were found to reduce restoration at the melodic level. Restoration at the submelodic level was investigated with scales and chords in Experiments 4 and 5. At this level, key-based expectations were found to increase restoration. Implications for music perception, as well as similarities between restoration in music and speech, are discussed. 相似文献

The present study examined the role of crosstalk in dual-task interference using a combination of a nonspeeded visual task
and an auditory-manual reaction time (RT) task. The potential for dual-task crosstalk was introduced by presenting in the
visual task objects (e.g., a cup with a handle), which “afford” associated responses that were either spatially compatible
or incompatible with the response in the RT task. Crucially, the degree of crosstalk was varied by instructing participants
either to attend to the left–right orientation of the objects, creating explicit cross-task response-code overlap (“strong
crosstalk”), or to attend to object identity (no direct overlap; “weak crosstalk”). The data indicated a relative benefit
for cross-task compatible trials, which was much greater with strong crosstalk than with weak crosstalk. Crucially, however,
even on compatible trials dual-task performance was substantially worse with strong crosstalk than with weak crosstalk. This
overall cost of crosstalk suggests interference of response codes even on compatible dual-task trials.

Motor theories of speech perception have been re-vitalized as a consequence of the discovery of mirror neurons. Some authors have even promoted a strong version of the motor theory, arguing that the motor speech system is critical for perception. Part of the evidence that is cited in favor of this claim is the observation from the early 1980s that individuals with Broca’s aphasia, and therefore inferred damage to Broca’s area, can have deficits in speech sound discrimination. Here we re-examine this issue in 24 patients with radiologically confirmed lesions to Broca’s area and various degrees of associated non-fluent speech production. Patients performed two same-different discrimination tasks involving pairs of CV syllables, one in which both CVs were presented auditorily, and the other in which one syllable was auditorily presented and the other visually presented as an orthographic form; word comprehension was also assessed using word-to-picture matching tasks in both auditory and visual forms. Discrimination performance on the all-auditory task was four standard deviations above chance, as measured using d′, and was unrelated to the degree of non-fluency in the patients’ speech production. Performance on the auditory–visual task, however, was worse than, and not correlated with, the all-auditory task. The auditory–visual task was related to the degree of speech non-fluency. Word comprehension was at ceiling for the auditory version (97% accuracy) and near ceiling for the orthographic version (90% accuracy). We conclude that the motor speech system is not necessary for speech perception as measured both by discrimination and comprehension paradigms, but may play a role in orthographic decoding or in auditory–visual matching of phonological forms. 相似文献

This study examined the effects that the acoustic-phonetic structure of a stimulus exerts on the processes by which lexical candidates compete for activation. An auditory lexical decision paradigm was used to investigate whether shortening the VOT of an initial voiceless stop consonant in a real word results in the activation of the lexical-semantic network of its voiced competitor, i.e., does acoustically modified time prime penny via dime. Results for normal subjects showed semantic priming for related pairs and mediated priming for voiced competitors, consistent with cascade models of language processing allowing for interaction between phonological and semantic levels of processing. Although Broca's aphasics showed semantic priming (dime primed penny), they failed to show priming in the context of a lexical competitor. These results are consistent with the hypothesis that these patients have a lexical processing deficit characterized by an overall reduction in lexical activation. 相似文献

The present study of two hundred and seven university students examined the structural relation of future-orientation (both valence and instrumentality), career decision-making self-efficacy and career indecision (choice/commitment anxiety and lack of readiness) in a sample of 218 college students. Future time perspective was viewed as a key input to career decision making. Structural equation modeling results indicated that valence was not significantly related to career decision-making self-efficacy, choice/commitment anxiety and lack of readiness. However, instrumentality completely mediated the relation between valence and career decision-making self-efficacy, choice/commitment anxiety and lack of readiness. Instrumentality was significantly related to career decision-making self-efficacy and lack of readiness. Career decision-making self-efficacy completely mediated the relation between instrumentality and choice/commitment anxiety; however, it only partially mediated the relation between instrumentality and lack of readiness. Although the proposed model was invariant across gender, the findings indicated that women reported higher instrumentality and lower lack of readiness than did men. No differences were found for career decision-making self-efficacy and choice/commitment anxiety across gender. The findings suggest that psychologists, counselors, and teachers should consider the role of future time perspective in university students' career development. 相似文献

Maladaptive emotion regulation is a risk factor for depression when an individual is experiencing stressful interpersonal events. Although emotion regulation has several different dimensions, little is known about which of these mediate the relationship between interpersonal stress and depressive symptoms. The current study examined self-ratings of emotion regulation, interpersonal stress, and depression in a sample of non-clinical undergraduate students (N = 152). Our results indicated that two facets of emotion regulation (i.e., lack of emotional clarity and limited access to emotion regulation strategies) fully mediate the relationship between interpersonal stress and depression. Hence, to minimize depressive symptoms when experiencing interpersonal stress, our findings suggest that it is important for individuals to be clear about their feelings and to attempt to transition from negative feelings to alternative feelings. 相似文献
