Two aspects of the amygdaloid complex (corticomedial and basolateral) were examined with reference to serotonergic inhibition of shock-induced aggression. Fighting was significantly depressed by serotonergic stimulation (5-HT, 10 μg bilateral) in the corticomedial amygdala while serotonergic blockade (methysergide, 5 μg bilateral) in this region increased levels of fighting. No consistent effects were obtained with serotonergic manipulation of the basolateral amygdala. Further investigation revealed that the state of serotonergic activity in medial amygdaloid sites was associated with concomitant alterations in the animals' sensitivity to footshock. Results are discussed in relation to a) a general inhibitory role of serotonin in behavioural mechanisms and b) a dopaminergic-serotonergic balance for behavioural arousal involving medial amygdaloid nuclei. 相似文献

慢性疼痛与抑郁症具有高度共病性,但迄今尚无成熟理论能够阐释二者共病的神经心理机制。对慢性痛与抑郁的脑机制研究提示,慢性痛和抑郁常常涉及到相似的情绪脑区活动的异常改变;与此相对应的是,行为学研究发现,疼痛患者与抑郁患者在加工疼痛或抑郁相关信息时表现出了模式相似的认知情绪偏差(CAB)。近年来,越来越多证据趋于一致,指出慢性痛和抑郁共有的情绪通路异常变化可能导致了相似的信息加工异常,是二者共病的神经心理基础,而认知情绪偏差则在行为上反映了这种变化,并且很可能是共病发生、发展及维持的重要因素。 相似文献

中学生心理危机分类模型属于复杂数据模型,本文采用分类树算法探究家庭、校园、同伴和个体因素在中学生心理危机分类中的相对重要性差异,尤其是心理痛苦三因素对致死性危机的独特作用。结果显示:(1)中学生自杀危机和非致死性危机分类树的分类效果良好,自伤危机分类树的分类效果欠佳;(2)中学生自杀危机中,痛苦逃避最为重要,痛苦唤醒次之,之后为痛苦体验和学校满意度;(3)中学生自伤危机中,同伴问题行为最为重要,之后为父母陪伴和家庭监督;(4)中学生非致死性危机中,歧视知觉最为重要,之后为痛苦唤醒和同伴支持。提示中学生不同心理危机的促发机制存在差异,心理痛苦三因素模型在自杀分类模型中作用显著,但并非自伤危机和非致死性危机的关键变量。 相似文献

Dialogue has its origins in joint activities, which it serves to coordinate. Joint activities, in turn, usually emerge in hierarchically nested projects and subprojects. We propose that participants use dialogue to coordinate two kinds of transitions in these joint projects: vertical transitions, or entering and exiting joint projects; and horizontal transitions, or continuing within joint projects. The participants help signal these transitions with project markers, words such as uh‐huh, m‐hm, yeah, okay, or all right. These words have been studied mainly as signals of listener feedback (back‐channel signals) or turn‐taking devices (acknowledgment tokens). We present evidence from several types of well‐defined tasks that they are also part of a system of contrasts specialized for navigating joint projects. Uh‐huh, m‐hm and yeah are used for horizontal transitions, and okay and all right for vertical transitions. 相似文献

We evaluated the effects of cartoon viewing with the use of a star feedback chart on two burned children's pain behavior during their physical therapy sessions. In addition, the degree to which the observational data corresponded with physical therapists' and mothers' ratings of the children's pain, fear, and cooperativeness was examined. Using a reversal single-subject design, the results showed that the children's pain behavior substantially decreased during experimental treatment sessions compared to their baseline levels. The rating scale data indicated that the physical therapist's and mother's rating of pain, anxiety, and cooperativeness were all correlated significantly with the observational data (p < .05). The contributions of respondent and operant conditioning to the occurrence and treatment of pain behavior in burned children are discussed. 相似文献

Chronic pain impacts individuals with pain as well as their loved ones. Yet, there has been little attention to the social context in individual psychological treatment approaches to chronic pain management. With this need in mind, we developed a couple-based treatment, “Mindful Living and Relating,” aimed at alleviating pain and suffering by promoting couples’ psychological and relational flexibility skills. Currently, there is no integrative treatment that fully harnesses the power of the couple, treating both the individual with chronic pain and the spouse as two individuals who are each in need of developing greater psychological and relational flexibility to improve their own and their partners’ health. Mindfulness, acceptance, and values-based action exercises were used to promote psychological flexibility. The intervention also targets relational flexibility, which we define as the ability to interact with one’s partner, fully attending to the present moment, and responding empathically in a way that serves one’s own and one’s partner’s values. To this end, the intervention also included exercises aimed at applying psychological flexibility skills to social interactions as well as emotional disclosure and empathic responding exercises to enhance relational flexibility. The case presented demonstrates that healthy coping with pain and stress may be most successful and sustainable when one is involved in a supportive relationship with someone who also practices psychological flexibility skills and when both partners use relational flexibility skills during their interactions. 相似文献

Perceived burdensomeness (PB), the perception of being a burden to others, is associated with pain and physical symptoms. Anxiety sensitivity (AS), the fear of arousal-related sensations, arising from beliefs that the sensations may have adverse personal consequences (physical, cognitive, and social), may increase risk for pain responding, particularly in anxiety-provoking (e.g. socially threatening) contexts. Accordingly, individuals high in AS may have a stronger pain response when experiencing PB than those low in AS. Undergraduate participants (n = 262) completed the Anxiety Sensitivity Index (ASI-3), and then were randomly assigned to re-live an experience when they were either burdensome to others (burdensome condition) or contributed equally to a group (control condition). Both social and physical self-reported pain were assessed post-manipulation. Those high in AS reported significantly higher pain ratings in the burdensome condition than the control condition; for those low in AS, pain did not change across conditions. In particular, being fearful of the physical repercussions of anxiety (AS physical concerns) while also feeling burdensome to others was associated with greater physical pain. AS may exacerbate the already painful effects of feeling burdensome to others, and may have important implications for the development of future suicide- and pain-related interventions. 相似文献

To better understand the cultivation of positive intra- and interpersonal emotions, we examined an argument that some effects of contemplative training result from language processing. We presented participants with loving-kindness language used in kindness-meditation training studies and asked them to rate imagined pain. If loving-kindness language processing is responsible for some effects recently reported we expected this language could affect intra- and interpersonal sensitivity. Loving-kindness-language participants rated imagined other-pain significantly higher and imagined self-pain significantly lower than closely matched control participants. As a result of this interaction, the loving-kindness-language group showed no significant difference between self-pain and other-pain, whereas controls rated self-pain significantly higher than other-pain. These results suggest that exposure to loving-kindness-language in Loving-Kindness Meditation leads to changes in sensitivity to own and vicarious distress without explicit training. These findings underscore that meditation-like effects may be easily induced. Further research is needed to determine duration and degree of effect. 相似文献
