The social brain undergoes developmental change during adolescence, and pubertal hormones are hypothesized to contribute to this development. We used fMRI to explore how pubertal indicators (salivary concentrations of testosterone, oestradiol and DHEA; pubertal stage; menarcheal status) relate to brain activity during a social emotion task. Forty‐two females aged 11.1 to 13.7 years underwent fMRI scanning while reading scenarios pertaining either to social emotions, which require the representation of another person’s mental states, or to basic emotions, which do not. Pubertal stage and menarcheal status were used to assign girls to early or late puberty groups. Across the entire sample, the contrast between social versus basic emotion resulted in activity within the social brain network, including dorsomedial prefrontal cortex (DMPFC), the posterior superior temporal sulcus, and the anterior temporal cortex (ATC) in both hemispheres. Increased hormone levels (independent of age) were associated with higher left ATC activity during social emotion processing. More advanced age (independent of hormone levels) was associated with lower DMPFC activity during social emotion processing. Our results suggest functionally dissociable effects of pubertal hormones and age on the adolescent social brain.  相似文献

This study examined whether emotion processing traits and task performance are associated with positive schizotypy. Positive schizotypy individuals (n=34, assessed with the Magical Ideation and Perceptual Aberration Scales) reported greater attention to emotions but less emotional clarity than controls (n=56). Moreover, a significantly larger percentage of the schizotypy group was classified as emotionally overwhelmed. Positive schizotypy individuals also exhibited absent affective priming and increased incongruent errors at a short stimulus onset asynchrony and an absence of an effect of emotion on recognition memory, but an increased memory response bias for negative words. Results could not be accounted for by level of neuroticism or current mood. These results suggest that positive schizotypy is associated with the processing of emotional information.  相似文献

This study examined the effect of provocateurs' emotion displays on first through fourth graders' social information processing (SIP). Rating and nomination sociometric techniques were used to identify rejected-aggressive, rejected-nonaggressive, average-nonaggressive, and popular-nonaggressive groups. Children viewed videotaped ambiguous provocation situations in which provocateurs' emotion displays were varied systematically. After each vignette, children's recall of story details, attribution of intent, and problem-solving responses were obtained. Half of the children were randomly assigned to a condition where they were asked directly about provocateurs' emotions, and the remaining children were not asked about provocateurs' feelings. Results revealed both developmental and social adjustment differences in SIP. In addition, provocateurs' emotion displays and asking versus not asking about those displays influenced multiple aspects of SIP.  相似文献

ABSTRACT

Background and Objectives: Negative cognitive emotion regulation (ER) strategies are particularly important within the framework of anxiety problems amongst youths and how they cope with stressful events. The aim of this study was to examine the associations between both negative and positive ER style and cardiac regulation under stressful conditions.

Design: Eighty-nine adolescents (M?=?13.31 years, SD?=?0.68, 44.94% girls) were exposed to a socially relevant stress induction protocol.

Methods: Participants’ emotion regulation strategies were assessed and their cardiac function was recorded.

Results: A negative ER style predicted heart rate (HR) entropy at the stressful stage after controlling for anxiety scores. In addition, heart rate variability reactivity and recovery and HR entropy recovery were larger (p?<?.05) in the low negative ER style group (n?=?16) than in the high negative ER style group (n?=?23).

Conclusions: Results suggest that individuals with a highly negative ER style have diminished autonomic flexibility.  相似文献

The degree to which emotional aspects of stimuli are processed automatically is controversial. Here, we assessed the automatic elicitation of emotion-related brain potentials (ERPs) to positive, negative, and neutral words and facial expressions in an easy and superficial face-word discrimination task, for which the emotional valence was irrelevant. Both emotional words and facial expressions impacted ERPs already between 50 and 100 ms after stimulus onset, possibly reflecting rapid relevance detection. Following this initial processing stage only emotionality in faces but not in words was associated with an early posterior negativity (EPN). Therefore, when emotion is irrelevant in a task which requires superficial stimulus analysis, automatically enhanced sensory encoding of emotional content appears to occur only for evolutionary prepared emotional stimuli, as reflected in larger EPN amplitudes to faces, but not to symbolic word stimuli.  相似文献

Cognitive models of social phobia (SP) assume that following social evaluative stress, individuals with SP engage into dysfunctional post-event processing (PEP), a detailed negative review of the past event. While previous research has already shown, that children with high levels of social fears suffer from more frequent negative PEP, it remains unclear how stable PEP is across time in this age group and whether it leads to degraded self-appraisals of performance. Therefore in the present study we exposed a group of high (HSA) and low socially anxious children (LSA; both n = 20), aged 10–12 years, to a social evaluative situation and assessed negative and positive PEP as well as self-rated performance at 2.5 h and one week after the task. Our results revealed that HSA children reported more negative PEP than LSA children, independent of levels of depression. Moreover, negative PEP was related to measures of social anxiety and performance ratings within the tasks. Only the performance ratings in HSA children worsened over the course of the following week and were related to more negative PEP. Thus, these results speak for the high clinical relevance dysfunctional PEP may have for the maintenance of social fears already in childhood.  相似文献

The voice is a marker of a person's identity which allows individual recognition even if the person is not in sight. Listening to a voice also affords inferences about the speaker's emotional state. Both these types of personal information are encoded in characteristic acoustic feature patterns analyzed within the auditory cortex. In the present study 16 volunteers listened to pairs of non-verbal voice stimuli with happy or sad valence in two different task conditions while event-related brain potentials (ERPs) were recorded. In an emotion matching task, participants indicated whether the expressed emotion of a target voice was congruent or incongruent with that of a (preceding) prime voice. In an identity matching task, participants indicated whether or not the prime and target voice belonged to the same person. Effects based on emotion expressed occurred earlier than those based on voice identity. Specifically, P2 (approximately 200 ms)-amplitudes were reduced for happy voices when primed by happy voices. Identity match effects, by contrast, did not start until around 300 ms. These results show an early task-specific emotion-based influence on the early stages of auditory sensory processing.  相似文献

The aim of the present study was to compare the performance of older and younger adults on an emotional priming task. Moreover, a nonemotional priming paradigm was used as a control task to disentangle age-related changes due to emotional processing difficulties from modifications due to a decline of executive inhibitory control abilities. Twenty-two young and 22 older healthy participants completed an emotional priming task and a nonemotional priming task. In the older adult group, reaction times in the emotional priming paradigm were not influenced by any of the prime conditions, whereas both groups exhibited similar facilitation effects induced by the congruent prime in the nonemotional task. The selective lack of an emotional priming effect in older adults shown in this preliminary report suggests that aging-induced changes in the ability to recognize emotions implicitly are directly dependent on emotional processing difficulties and not due to a general age-related modification of cognitive processes.  相似文献

The human face conveys important social signals when people interact in social contexts. The current study investigated the relationship between face recognition and emotional intelligence, and how societal factors of emotion and race influence people's face recognition. Participants’ recognition accuracy, reaction time, sensitivity, and response bias were measured to examine their face‐processing ability. Fifty Caucasian undergraduates (38 females, 12 males; average age = 21.76 years) participated in a face recognition task in which they discriminated previously presented target faces from novel distractor faces. A positive correlation between participants’ emotional intelligence scores and their performance on the face recognition task was observed, suggesting that face recognition ability was associated with emotional or social intelligence. Additionally, Caucasian participants recognized happy faces better than angry or neutral faces. It was also observed that people recognized Asian faces better than Caucasian ones, which appears to be contradictory to the classic other‐race effect. The present study suggests that some societal factors could influence face processing, and face recognition ability could in turn predict social intelligence.  相似文献

This study examined both perceiver and poser asymmetries in processing facial emotion. Posers were left brain-damaged (LBD), right brain-damaged (RBD), and normal control (NC) right-handed males videotaped while expressing happiness and anger. Perceivers rated the facial expressions for asymmetry in original and reversed orientations. Overall, expressions viewed in the reversed orientation were rated as more left-sided than in the original orientation. In the reversed orientation, the more extensive left hemiface of the NCs and LBDs fell in the perceiver's left hemispace. This finding is consistent with previous research demonstrating a left hemispace bias for free-field viewing of emotional faces. Expressions were produced significantly more intensely on the left than the right hemiface by NCs and LBDs; expressions of RBDs were not significantly lateralized.  相似文献

Negative life events, cognitive emotion regulation and emotional problems   总被引:1,自引:0,他引:1  
A new questionnaire, named the Cognitive Emotion Regulation Questionnaire, has been constructed, measuring nine cognitive coping strategies people tend to use after having experienced negative life events. A test–retest design was used to study the psychometric properties and relationships with measures of depression and anxiety among 547 high school youngsters. Principal component analyses supported the allocation of items to subscales, while alphas of most subscales exceeded 0.80. Cognitive coping strategies were found to play an important role in the relationship between the experience of negative life events and the reporting of symptoms of depression and anxiety. The results suggest that cognitive coping strategies may be a valuable context of prevention and intervention  相似文献

Incarcerated males who score high on personality measures of psychopathy are reported to be less efficient than other incarcerated males in processing emotionally laden stimuli. In this study, we evaluated whether an emotion deficit is also present in non-incarcerated higher functioning males who score high on psychopathy personality measures. A sample of male university students was screened for psychopathic personality, and two subsamples, those who scored high or low on global psychopathy, participated in a series of language processing tasks designed to assess verbal emotion processing. Unlike previous studies of emotion processing in the verbal domain, stimuli also systematically varied in abstractness. The results showed that participants scoring high in psychopathy were less efficient than those scoring low in psychopathy in processing negatively valenced words, across all levels of word abstractness. The results extend previous accounts of emotional processing deficits in individuals with psychopathic personality to a relatively high-functioning non-incarcerated sample.  相似文献

Normal observers demonstrate a bias to process the left sides of faces during perceptual judgments about identity or emotion. This effect suggests a right cerebral hemisphere processing bias. To test the role of the right hemisphere and the involvement of configural processing underlying this effect, young and older control observers and patients with right hemisphere damage completed two chimeric faces tasks (emotion judgment and face identity matching) with both upright and inverted faces. For control observers, the emotion judgment task elicited a strong left-sided perceptual bias that was reduced in young controls and eliminated in older controls by face inversion. Right hemisphere damage reversed the bias, suggesting the right hemisphere was dominant for this task, but that the left hemisphere could be flexibly recruited when right hemisphere mechanisms are not available or dominant. In contrast, face identity judgments were associated most clearly with a vertical bias favouring the uppermost stimuli that was eliminated by face inversion and right hemisphere lesions. The results suggest these tasks involve different neurocognitive mechanisms. The role of the right hemisphere and ventral cortical stream involvement with configural processes in face processing is discussed.  相似文献

People with multiple sclerosis (MS) can experience problems in interpreting others’ emotions from faces or voices. However, to date little is known about whether difficulties in emotion perception in MS are related to broader aspects of social functioning. Also, there are few studies reporting the effect of MS on more ecologically valid assessments of emotion perception using multimodal videos. The current study looks at (1) the effect of MS on perceiving emotions from faces, voices and multimodal videos; (2) the possible role of slowed processing and executive dysfunction in emotion perception problems in MS and (3) the relationship between emotion perception and broader social functioning in MS. 53 people with MS and 31 healthy controls completed tasks of emotion perception and cognition, and assessed their levels of social support and social participation. Participants with MS performed worse than demographically matched controls on all measures of emotion perception. Emotion perception performance was related to cognitive measures in those with MS. Also, significant associations were found between emotion perception difficulties in MS and poorer social function. In particular, people with MS who had poorer emotion perception also reported lower levels of social support from their friends, and regression analysis showed that this prediction was maintained even when disease severity and cognitive function were taken into account. These results show that problems with emotion perception in MS extend to more realistic tasks and may predict key aspects of social functioning.  相似文献

Patients with social phobia report experiencing negative images of themselves performing poorly when in feared social situations. The present study investigates whether such negative self-imagery (based on memory of past social situations) contaminates social interactions. High socially anxious volunteers participated in two conversations with another volunteer (conversational partner). During one conversation, the socially anxious volunteers held in mind a negative self-image, and during the other they held in mind a less negative (control) self-image. As predicted, when holding the negative image the socially anxious volunteers felt more anxious, reported using more safety behaviours, believed that they performed more poorly, and showed greater overestimation of how poorly they came across (relative to ratings by the conversational partner). Conversational partners rated the socially anxious volunteers' performance as poorer in the negative image condition. Furthermore, the conversation was contaminated since both groups of participants rated its quality as poorer in the negative image condition.  相似文献

Repeated and orthographically similar words are vulnerable in RSVP, as observed using the repetition blindness (RB) paradigm. Prior researchers have claimed that RB is increased for emotion words, but the mechanism for this was unclear. We argued that RB should be reduced for words with properties that capture attention, such as emotion words. Employing orthographic repetition blindness, our data showed that words with negative emotional valence had a report advantage when they were the second of two similar words (e.g., less RB occurred with HORSE curse than with HORSE purse). This renders emotion RB similar to the use of emotion words in the attentional blink phenomenon. The findings demonstrate the neglected role of competition in conscious recognition of multiple words under conditions of brief display and masking.  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

According to the broaden-and-build theory, positive emotions broaden one's thought-action repertoire, which may manifest as a widened attentional scope in cognitive processing. The present study directly tests this hypothesis by examining the influences of induced emotions (positive, neutral and negative) on holistic processing of face (Experiment 1) and face discrimination (Experiment 2). In both experiments, emotions induced with images from the International Affective Picture System significantly interacted with face processing. That is, positive emotions engendered greater holistic face encoding in a composite-face task in Experiment 1 and more accurate face discrimination in Experiment 2, relative to the neutral condition. In contrast, negative emotions impaired holistic face encoding in the composite-face task and reduced face discrimination accuracy. Taken together, these results provide further support for the attentional broadening effect of positive affect by demonstrating that induced positive emotions facilitate holistic/configural processing.  相似文献
