情绪表象是指个体在头脑中生成的含有情绪信息的画面。本文从情绪表象的视角出发,系统综述了抑郁症患者情绪表象的特征及影响机制。行为学结果初步证实,抑郁症患者存在消极表象加工偏向、积极表象能力受损和侵入性表象过多等功能不良表象特征。脑成像的研究初步表明,抑郁症功能不良表象与默认网络和前额叶的激活异常有关。表象的放大器效应和情绪调节策略分别用来解释情绪表象对抑郁症的发生和维持机制。建议未来的研究丰富测量手段和表象内容,进一步寻找抑郁症的特异性情绪表象特征。 相似文献

Facial Muscle Patterning and Subjective Experience During Affective Imagery: Sex Differences 总被引:1,自引:0,他引:1
Facial electromyographic (EMG) activity was recorded from the zygomatic, corrugator, masse-ter and frontalis muscle regions in 30 male and 30 female subjects. Forty-eight items were selected to reflect happy, sad, angry and fearful situations. Subjects imagined each of the items for 40 sec and rated how they felt on a scale tapping the four emotions. The results indicated that for certain emotions, muscle regions and ratings, females (as compared to males): 1) generated facial EMG patterns of greater magnitude (relative to rest) during affective imagery, 2) reported a stronger experience of emotion to the imagery, 3) showed greater within-subject correlations between the experience of emotions and facial EMG, 4) evidenced somewhat higher corrugator and significantly lower masseter EMG activity during rest, and 5) generated greater facial EMG changes during a post-imagery, voluntary facial expression condition. Cultural and biological interpretations of the data are considered. The importance of evaluating gender in psychophysiological studies of emotion is stressed. 相似文献

A multivariate pattern-classification system was developed for the study of facial electromy-ographic (EMG) patterning in 12 female subjects during affect-laden imagery and for posed facial expressions. A parameter-extraction procedure identified the dynamic EMG signal properties which accorded the maximal degree of self-reported emotion discrimination. Discriminant analyses on trialwise EMG vectors allowed assessment of specific EMG-site conformations typifying rated emotions of happiness, sadness, anger, and fear. The discriminability among emotion-specific EMG conformations was correlated with subjective ratings of affective-imagery vividness and duration. Evidence was obtained suggesting that the EMG patterns encoded complex, “blended” reported affective states during the imagery. Classification analyses produced point-predictions of reported emotional states in 10 of the 12 subjects, and provided the first computer pattern recognition of self-reported emotion from psychophysiological responses. 相似文献

Brain Mechanisms Subserving Self-Generated Imagery: Electrophysiological Specificity and Patterning 总被引:2,自引:0,他引:2
The present study was designed to assess the patterning of occipital and sensorimotor EEG activation during self-generated visual and kinesthetic imagery. Twenty subjects were requested to imagine, in separate trials, a flashing light, a tapping sensation on the right forearm, and both the light and the tapping together. Prior to the imagery trials, subjects were exposed to the stimuli which they were asked to subsequently imagine. EEG was recorded from the left occipital and left sensorimotor regions, filtered for alpha and quantified on-line. The results indicated that self-generated visual imagery elicited greater relative occipital activation than comparable kinesthetic imagery. The imagine-both condition fell predictably in between the two unimodal imagery conditions. The difference between visual and kinesthetic imagery was primarily a function of greater occipital activation during the former versus the latter task. No difference in overall alpha abundance among the three imagery tasks was found. These findings suggest that the self-generation of imagery in different modalities elicits specific changes in the sensory regions of the brain responsible for processing information in the relevant modalities. 相似文献

This paper explores the uses of imagery within behavioral and cognitive-behavioral clinical interventions. The nature of imagery as a central human phenomenon is first examined and then recent theoretical models of the role of imagery in therapy are reviewed and evaluated critically. A trend towards broader conceptualizations of the role of imagery in treatment is highlighted. The notion of self-efficacy and its role in imagery methods is discussed. The specific kinds of imagery techniques that have been practiced, including systematic desensitization, positive imagery, covert conditioning, implosive imagery and others, are briefly described and research results bearing on their effectiveness are presented. The assessment of imagery for clinical purposes is outlined and the possibilities for enhancing imagery capabilities are explored. The paper concludes on a note of cautious optimism about the potential of imagery therapies, acknowledging the limitations of imagery. Finally, it is proposed that clinicians should adopt a “research perspective” to collect information on the effectiveness of their procedures and provide data which could be used to correct the course of therapy as needed. 相似文献

People can learn to control the 8-12 Hz mu rhythm and/or the 18-25 Hz beta rhythm in the EEG recorded over sensorimotor cortex and use it to control a cursor on a video screen. Subjects often report using motor imagery to control cursor movement, particularly early in training. We compared in untrained subjects the EEG topographies associated with actual hand movement to those associated with imagined hand movement. Sixty-four EEG channels were recorded while each of 33 adults moved left- or right-hand or imagined doing so. Frequency-specific differences between movement or imagery and rest, and between right- and left-hand movement or imagery, were evaluated by scalp topographies of voltage and r spectra, and principal component analysis. Both movement and imagery were associated with mu and beta rhythm desynchronization. The mu topographies showed bilateral foci of desynchronization over sensorimotor cortices, while the beta topographies showed peak desynchronization over the vertex. Both mu and beta rhythm left/right differences showed bilateral central foci that were stronger on the right side. The independence of mu and beta rhythms was demonstrated by differences for movement and imagery for the subjects as a group and by principal components analysis. The results indicated that the effects of imagery were not simply an attenuated version of the effects of movement. They supply evidence that motor imagery could play an important role in EEG-based communication, and suggest that mu and beta rhythms might provide independent control signals. 相似文献

Fear Imagery and Text Processing 总被引:7,自引:0,他引:7
This study examined the effect of three variables held to influence heart rate response during imagery-related text processing: mode of processing, content of text, and inclusion of response information in the text. Sixty-four undergraduates imagined and silently repeated fearful and neutral sentences in a paradigm designed to allow for self-initiation of sentence processing. Fear sentences either included or did not include information about bodily responses in the image. Heart rate accelerated more during fear imagery than during neutral imagery or silent repetition of either type of sentence. Inclusion of response information in fear material did not increase heart rate response to imagery, but did affect self-report in the predicted direction. Heart rate waveform prior to the sentence tasks indicated pre-processing of fearful material. The results were discussed in relation to a bio-informational theory of imagery, which asserts that emotional imagery accesses the same centrally-mediated response program as is evoked in the target reality context, and thus occasions measurable activity in the appropriate effectors. 相似文献

Mental imagery has been considered relevant to psychopathology due to its supposed special relationship with emotion, although evidence for this assumption has been conspicuously lacking. The present review is divided into four main sections: (1) First, we review evidence that imagery can evoke emotion in at least three ways: a direct influence on emotional systems in the brain that are responsive to sensory signals; overlap between processes involved in mental imagery and perception which can lead to responding “as if” to real emotion-arousing events; and the capacity of images to make contact with memories for emotional episodes in the past. (2) Second, we describe new evidence confirming that imagery does indeed evoke greater emotional responses than verbal representation, although the extent of emotional response depends on the image perspective adopted. (3) Third, a heuristic model is presented that contrasts the generation of language-based representations with imagery and offers an account of their differing effects on emotion, beliefs and behavior. (4) Finally, based on the foregoing review, we discuss the role of imagery in maintaining emotional disorders, and its uses in psychological treatment. 相似文献

The psychophysiology of disgust: Differentiating negative emotional contexts with facial EMG 总被引:6,自引:0,他引:6
SCOTT R. VRANA 《Psychophysiology》1993,30(3):279-286
The goals of this study were (a) to examine differing views on the relationship between self-report of emotion and physiological expression of emotion, (b) to differentiate between negative emotional contexts during imagery using facial electromyogram (EMG), and (c) to describe the facial muscle patterning and autonomic physiology of situations that involve expelling or avoiding disgusting sensory stimulation. Fifty subjects imagined situations eliciting disgust, anger, pleasure, and joy in 8-s trials using a tone-cued imagery procedure. Heart rate, skin conductance level, and facial EMG at the corrugator, zygomatic, and levator labii superioris/alesque muscle regions were recorded during imagery, and self-reports of emotion were collected after imagery trials. Self-reports of emotion produced results consistent with the affective categorization of the images. Activity at the levator labii region was higher during disgust than during anger imagery. Corrugator region increase characterized the negative as compared with the positive emotional contents, and activity at the zygomatic region was higher during joy imagery than during the other three emotions. Heart rate acceleration was greater during disgust, anger, and joy imagery than during pleasant imagery. Disgust imagery could be discriminated from anger imagery using facial EMG, and the expressive physiology of disgust was occasioned by the action set of active avoidance or rejection of sensory stimulation. 相似文献

Sixty subjects were exposed for 40 s each to 48 imagery situations designed to reflect happy, sad, angry and fearful conditions. Facial electromyographic (EMG) activity from zygomatic, corrugator, masseter and lateral frontalis muscle regions was recorded, and experienced emotion was measured on a scale tapping these four emotions. Results showed that: (1) zygomatic activity reliably differentiated happy imagery, corrugator activity reliably differentiated sad imagery, but masseter activity did not differentiate angry imagery and lateral frontalis activity did not differentiate fearful imagery; (2) different intensities of specific emotional imagery situations evoked the expected differential patterns of self-report and EMG; (3) higher correlations between self-report and EMG for ‘present’, rather than ‘future’ ratings of experienced emotion emerged for positive affect only; and (4) the use of a standardized imagery scale, rather than the self-generated, personally-relevant affective situations used in previous studies, allowed for more sensitive measurement of the relationship between facial muscle activity and subjective experience of emotion during affective imagery. 相似文献
