This study examined age differences in phasic heart rate in response to neutral, negative and positive pictures. Heart rate changes and subjective ratings were analyzed in 22 middle-aged (40-55 years) and 30 older (56-78 years) participants. The effects of valence on the HR pattern across time were similar to that obtained by Bradley and co-workers. Conversely to previous studies, we did not report any age-related reduction in cardiac reactivity. Instead, when viewing positive pictures, the triphasic wave form appeared in the group of older adults, but for younger participants, it was replaced by a sustained deceleration. These results were interpreted in the light of the socioemotional selectivity theory.  相似文献

This experiment investigated the role of conflict in the response and evaluative categorization systems in the affective congruency effect using event-related brain potentials (ERPs). Participants completed a primed evaluative decision task in which the proportion of congruent to incongruent trials was manipulated. The size of the affective congruency effect increased along with the proportion of congruent trials. ERP data identified the locus of this effect in the response system: the lateralized readiness potential (LRP) showed that preferential response activation occurred in motor cortex following prime onset, and the fronto-central N2 (conflict monitoring) component indicated that conflict occurred when the response activated by the prime differed from the target response, irrespective of the affective congruency of the prime and target. The extent of this conflict covaried with strategic processing of primes, as participants directed less attention to primes that were likely to elicit conflict. These data support a response conflict account of affective congruency effects in the evaluative decision task and indicate that strategic control of attention is important in determining the extent to which conflict occurs.  相似文献

Previous studies have identified two powerful ways to regulate emotional responses to a stressor: experiencing incidental positive emotions and using cognitive reappraisal to reframe the stressor. Several cognitive and motivational theories of positive emotion support the formulation that incidental positive emotions may facilitate cognitive reappraisal. To test the separate and interacting effects of positive emotions and cognitive reappraisal, we first adapted an established picture-based reappraisal paradigm by interspersing blocks of positive emotion inducing and neutral pictures. Across two pre-registered studies (Studies 1, 2), reappraisal effectively decreased self-reported negative emotions and increased self-reported positive emotions; however, experiencing incidental positive emotions did not facilitate reappraisal success. In another preregistered study (Study 3), we employed a more powerful positive emotion induction via virtual reality (VR), used a social stress anticipation task, and instructed participants to reappraise the anticipated stressor positively. Although there was a robust effect of the positive emotion induction (relative to the neutral induction) on feeling more positive emotions throughout stress anticipation, the results again indicated that incidental positive emotions did not facilitate cognitive reappraisal. We propose that incidental positive emotions and cognitive reappraisal may constitute separate pathways of influence when regulating one's responses to negative events.  相似文献

The aim of this research was to study the influence of both the emotional content and the physical characteristics of affective stimuli on the psychophysiological, behavioral and cognitive indexes of the emotional response. We selected 54 pictures from the IAPS, depicting unpleasant, neutral, and pleasant contents, and used two picture sizes as experimental conditions (120 x 90 cm and 52 x 42 cm). Sixty-one subjects were randomly assigned to each experimental condition. We recorded the startle blink reflex, skin conductance response, heart rate, free viewing time, and picture valence and arousal ratings. In line with previous research (e.g., Bradley, Codispoti, Cuthbert, and Lang, 2001), our data showed an effect of the affective content on all the measurements recorded. Importantly, effects of the size of the affective pictures on emotional responses were not found, indicating that the emotional content is more important than the formal properties of the stimuli in evoking the emotional response.  相似文献

This brief commentary highlights seven sins in the study of emotion that are explicitly treated in contemporary affective neuroscience. These sins are (1) Affect and cognition are subserved by separate and independent neural circuits; (2) Affect is subcortical; (3) Emotions are in the head; (4) Emotions can be studied from a purely psychological perspective; (5) Emotions are similar in structure across age and species; (6) Specific emotions are instantiated in discrete locations in the brain; and (7) Emotions are conscious feeling states. Each of these is briefly discussed and evidence from affective neuroscience that bears on these sins is noted. The articles in this Special Issue underscore the vitality of research in affective neuroscience and illustrate how some of these sins can be addressed and rectified using concepts and methods from affective neuroscience.  相似文献

Behold the wrath: Psychophysiological responses to facial stimuli   总被引:3,自引:0,他引:3  
The complex musculature of the human face has been shaped by natural selection to produce gestures that communicate information about intentions and emotional states between senders and receivers. According to the preparedness hypothesis, different facial gestures are differentially prepared by evolution to become associated with different outcomes. As attested by psychophysiological responses in Pavlovian conditioning experiments, expressions of anger and fear more easily become signals for aversive stimuli than do expression of happiness. Consistent with the evolutionary perspective, the superior conditioning to angry faces is stronger for male than for female faces, for adult than for child faces, and for faces directed toward the receiver rather than directed away. Furthermore, it appears to be primarily located in the right cerebral hemisphere. The enhanced autonomic activity to angry faces signaling electric shock is not mediated by conscious cognitive activity, but is evident also when recognition of the facial stimulus is blocked by backward masking procedures. Similarly, conditioned responses can be established to masked angry, but not to masked happy faces. Electromyographic measurement of facial muscle activity reveals a tendency for emotional facial expression to rapidly and automatically elicit its mirror image in the face of the receiver, typically accompanied by the appropriate emotional experience. The research reviewed in this paper supports the proposition that humans have been evolutionarily tuned to respond automatically to facial stimuli, and it is suggested that such early automatic reactions shape the subsequent conscious emotional processing of the stimulus.The responsibility for this paper is shared equally between the authors. The research reviewed in the paper has been supported by separate grants to both authors from the Swedish Council for Research in the Humanities and Social Sciences, The Swedish Council for the Coordination and Planning of Research, and the Bank of Sweden Tercentennial Fund.  相似文献

Executive functions (EF) and especially inhibition have been shown to play an essential role in team sports. However, the underlying cortical mechanisms of EF in real game situations are barely understood, since previous studies predominantly used tests with simplified stimuli in seated positions. Consequently, the aim of the current study was to explore cortical responses to sport-specific stimuli in a standing stop signal task (SST). Cortical activity was investigated in 17 adult amateur soccer players using mobile electroencephalography (EEG) in a standard- (Std) and a sport-specific (Sp) SST. Whereas mean reaction times were significantly longer in the Sp-SST, stop error-rates demonstrated no significant difference. Further, analysis of event-related spectral perturbation (ERSP) in a frontal cluster also showed no significant differences between Std- and Sp-SST for go and stop conditions. Thus, sport-specific stimuli in a standing SST may exhibit similar inhibitory cortical processes as the standard SST, although requiring longer processing times with regards to the more complex visual stimulation. Future studies are needed to further develop realistic paradigms for evaluating sport-specific cognitive performance.  相似文献

The intention of this paper is to reveal how emotional dynamics of girls' fear and repulsion of fat operate within spaces of physical activity including Physical Education (PE). Through engagement with girls' everyday embodied experiences, understandings and practices of physical activity this paper weaves dialogue between contemporary obesity and health discourses and girls' emotional embodied experiences of encountering material and non-tangible spaces of physical activity. This paper draws from PhD research of a feminist ethnographic study with PE teachers and female pupils in Scottish primary and secondary schools; the paper reveals girls encounters with both material objects – such as swimming pool water—and non-material, discursive spaces of school-based physical activity, rooted within contemporary health discourses which perpetuate a ‘fear of fatness’. Such intra-active encounters reveal new ways of understanding how girls and young women come to feel their bodies inside of contemporary obesity debates.  相似文献

The present study examined how contextual learning and in particular emotionality conditioning impacts the neural processing of words, as possible key factors for the acquisition of words’ emotional connotation. 21 participants learned on five consecutive days associations between meaningless pseudowords and unpleasant or neutral pictures using an evaluative conditioning paradigm. Subsequently, event-related potentials were recorded while participants implicitly processed the learned emotional relevance in a lexical decision paradigm. Emotional and neutral words were presented together with the conditioned pseudowords and a set of new pseudowords. Conditioned and new pseudowords differed in the late positive complex. Emotionally and neutrally conditioned stimuli differed in an early time window (80–120 ms) and in the P300. These results replicate ERP effects known from emotion word recognition and indicate that contextual learning and in particular evaluative conditioning is suitable to establish emotional associations in words, and to explain early ERP effects in emotion word recognition.  相似文献

ObjectivesThis study tested the generalizability of basic needs theory (BNT; Deci & Ryan, 2000) across situations in which dancers learn and perform within vocational dance. Specifically, we examined the inter-relationships between daily and typical perceptions of autonomy support, basic psychological need satisfaction, and changes in affective states, across dance situations that were divergent in their learning and evaluative potential (dance classes, rehearsals, and performances). Genre differences were also examined.DesignA one-month diary study examined the inter-relationships between typical and daily perceptions of autonomy support, basic psychological need satisfaction and positive and negative affect among dancers studying three distinct genres and in three situations (classes, rehearsals, performances).MethodFifty-five dancers completed a series of scales tapping the variables of interest. Abbreviated versions of the scales were completed before (affective states) and after (affective states, basic needs and autonomy support) dance classes, rehearsals and performances over four weeks. Analyzes tested the BNT sequence across the learning and performance situations. Interactions between typical and state experiences were tested. Cross-genre comparisons were also made.ResultsResults partially supported the BNT sequence across classes, rehearsals and performances. There were situational differences in the salience of each need as a predictor of affective states. When comparing genres, some differences were also found in perceived autonomy support, basic need satisfaction and affective states.ConclusionsFindings point to the importance of promoting autonomy supportive dance teaching to facilitate dancers' day-to-day experiences of well-being.  相似文献

Instances of sustained cooperative behaviour in humans can be considered as an adaptive strategy that enhances the probability of reaching a goal. This study investigates psychophysiological responses to cooperation in healthy subjects, while considering outcome and gender as potential moderators of these responses. Salivary cortisol levels (Csal), heart rate (HR), skin conductance level (SCL), nonspecific skin conductance responses (NSRs), and mood states were measured at different points before, during and after a Lego house‐building task in undergraduate men (n = 22) and women (n = 20). Once the task was finished, the experimenter informed the participants about the outcome obtained (positive or negative). Cooperation produces an increase in HR, SCL, and NSR responses. When the outcome is positive it produces a gradual diminution in Csal levels, but when the outcome is negative there is a significant increase in Csal levels after the task followed by a progressive decrease. Men with positive outcomes showed a lower area under curve (AUC) in Csal than women with a negative outcome. Men had more NSR responses in all periods other than the rest period. Several mood states are differently affected by the combined effect of outcome and gender. Our laboratory results can be generalized to other situations in which negotiation, mediation, and cooperative strategies are relevant for taking decisions and/or solving problems.  相似文献

This study investigated whether individualism-collectivism (cultural) differences would account for the observed relationship between ethnic group status and affective responses to and fairness perceptions of affirmative action interventions. Forty-nine international (Latin America and East Asia), 116 minority, and 106 majority participants from a major southwestern university and its community provided fairness and affective response ratings to an affirmative action scenario. Implementation policy and qualification of the recipient were also manipulated. Though ethnicity was related to individualism-collectivism, the latter did not explain any variance in affective response ratings. Minority and international participants reported more positive affect and higher agreement and fairness levels than did majority participants. Participants in the preferential treatment and equally qualified conditions had more favorable responses than those in the reverse-discrimination and less qualified conditions.  相似文献

Subjects at three age levels were administered picture pair or word pair discrimination lists. They pronounced or pointed as a method of choice, and they pronounced or pointed at the correct item (or remained silent) during rehearsal. The results indicated that with picture pairs, pronunciation facilitated learning as a method of choice and a type of rehearsal in nursery school Ss. For fifth grade and college Ss, there was no significant difference between pronouncing and pointing as a method of choice. However, spoken rehearsal was superior to control performance for fifth grade Ss. College Ss performed equally well in the control and pronouncing conditions, but pointing during rehearsal produced significantly more errors than pronouncing. Word pairs produced no significant pronunciation effects. These results were discussed within an internalization of speech perspective.  相似文献

The present study investigated the role of emotional tone of voice in the perception of spoken words. Listeners were presented with words that had either a happy, sad, or neutral meaning. Each word was spoken in a tone of voice (happy, sad, or neutral) that was congruent, incongruent, or neutral with respect to affective meaning, and naming latencies were collected. Across experiments, tone of voice was either blocked or mixed with respect to emotional meaning. The results suggest that emotional tone of voice facilitated linguistic processing of emotional words in an emotion-congruent fashion. These findings suggest that information about emotional tone is used in the processing of linguistic content influencing the recognition and naming of spoken words in an emotion-congruent manner.  相似文献

A computer game was used to study psychophysiological reactions to emotion‐relevant events. Two dimensions proposed by Scherer (1984a, 1984b) in his appraisal theory, the intrinsic pleasantness and goal conduciveness of game events, were studied in a factorial design. The relative level at which a player performed at the moment of an event was also taken into account. A total of 33 participants played the game while cardiac activity, skin conductance, skin temperature, and muscle activity as well as emotion self‐reports were assessed. The self‐reports indicate that game events altered levels of pride, joy, anger, and surprise. Goal conduciveness had little effect on muscle activity but was associated with significant autonomic effects, including changes to interbeat interval, pulse transit time, skin conductance, and finger temperature. The manipulation of intrinsic pleasantness had little impact on physiological responses. The results show the utility of attempting to manipulate emotion‐constituent appraisals and measure their peripheral physiological signatures.  相似文献

Executive functions (EF) are crucial for the athletes’ success, and they are even more essential in open skill sports (e.g. volleyball and football). In these sports, due to continuously changing conditions, goal-directed behaviours need to be repeatedly adjusted and corrected. One of the most important EF is the ability to continuously switch between two different tasks being required in a random sequence. We used a task-switching protocol in elite volleyball athletes, usually playing different roles, with the aim of evaluating if each role is characterized by specific switching abilities. On the basis of the specific competences requested by the game, thirty-six elite volleyball athletes were assigned to three groups: Strikers, Defenders and Mixed. Each player completed a customized sport-specific task-switching paradigm. Data evidenced that each role has specific characteristics. In Reaction Times, the Strikers were the fastest to answer to stimuli, while the Defender group provided a worse performance, particularly when defensive actions, that probably require more cognitive elaboration, had to be processed. Different effects emerged by the Errors. In fact, the Mixed group, which was the one with more expertise, appeared to be more accurate in the responses.Although preliminary, these results showed a minimal degree of cognitive flexibility for highly specialized Strikers and a maximum level for Mixed, allowing thus to highlight specific profiles of athletes. Data observed indicate the possibility to develop a test assessing the executive domain during the recruitment in a team, revealing a useful tool for choosing the most suitable role.  相似文献

Verbally labelling emotional stimuli has been shown to reliably decrease emotional responding. The present study compared the use of identical emotional labels during two types of verbal labelling: subjective labelling of one's own emotional response and objective labelling of the stimulus. We recorded skin conductance responses (SCRs) to emotional pictures presented at four brief durations preceding a backward mask. We observed that as the exposure duration increased, SCRs decreased during objective labelling of the stimuli. However, when participants subjectively labelled their own emotional state, SCRs increased as exposure duration increased. In addition, subjective labelling produced larger SCRs than objective labelling at a shorter exposure duration when the presented stimuli were biologically prepared. These results indicate that only objective labelling results in decreased emotional responding, and describe a novel interaction between bottom-up stimulus characteristics and top-down cognitive effects on physiological responses.  相似文献

In four experiments we examined under what conditions children around 4 years of age could overcome their normal tendency to treat a picture as transparent and attend to it also as a thing in itself. In Experiment 1, many children chose a picture of food as something “you can really eat” even after having identified it as “just a picture.” In Experiment 2, however, children were able to respond appropriately to implicit requests for a picture as distinct from a real exemplar of the thing represented when the context indicated the correct response. In these tasks, children could succeed by treating picture status simply as an attribute. In Experiments 3 and 4, children were asked to comment on the appearance and reality of pictures, deceptive (trick) objects and real things. Significantly poorer performance on pictures and tricks than on real things suggested that some children have difficulty holding two interpretations of the same input; that is, understanding that a picture has two identities.  相似文献
