A comparison is presented between the behaviors of male rats and male stumptail macaques that occur when two unfamiliar males are paired for 10 min. Results which have been presented in detail in separate papers elsewhere are compared and discussed here in terms of the hypothetical organization of motivational systems. The following motivational mechanisms appear to be homologous in the rat and monkey: offense, defense, submission, male sex, self grooming, and allogrooming. Two motivational mechanisms are analogous but not homologous: patrol/marking in the rat and display in the monkey. There is a shift in sensory modality of motivating stimuli from olfaction in the rat to complex visual and auditory stimuli in the monkey. There is also a shift in the modalities of motor patterns from predominant use of the mouth by the rat to use of the hands by the monkey. Both shifts affect most or all motivational systems of social behavior. It is hypothesized that the outer parts of motivational systems, their sensory and motor interfaces with the environment, change more rapidly and incrementally during the course of mammalian evolution than does the inner part, the integrational portion that consists of the motivational mechanisms. 相似文献

师生之间的动机感染是指在课堂情境中动机定向由教师向学生传递的过程.学生对教师行为、情绪和课堂动机气氛等线索的社会知觉是动机感染发生的基础.当前研究中,期望形成模型和教学支持模型从不同角度解释了动机感染的潜在过程.基于社会认知的视角,推测出动机感染的发生机制包含学生无意识的自动的目标感染和有意识的满足基本心理需要两条路径.该机制需要进一步验证.未来研究应关注以下几点:(1)利用质的研究方法拓展研究思路;(2)注重文化和情境等变量在动机感染中的价值;(3)动机感染双向过程的系统研究. 相似文献

本研究通过两个实验考察不同效价度和唤醒度的情绪刺激是否存在动机倾向上的分离模式。实验1要求被试对表情图片的动机倾向(趋近/回避)进行主观评分,发现被试对低唤醒表情或积极表情有更加趋近的倾向。实验2以运动的线索启动动机倾向(趋近/回避),完成情绪词效价判断任务,从内隐的角度考察情绪刺激是否存在动机倾向上的分离模式,结果发现,被试对动机倾向一致的情绪刺激的反应时更快。趋近的消极情绪词比趋近的积极情绪词的N2波幅更大,远离的低唤醒情绪词比趋近的低唤醒情绪词的LPC波幅更大。结果说明积极或者低唤醒的情绪刺激引发趋近倾向,而消极或高唤醒的情绪刺激引发回避倾向。 相似文献

研究采用类比推理的四项比例式任务和事件相关电位技术,探究不同回避动机强度的消极情绪(恐惧—高动机强度、悲伤—低动机强度、中性情绪)对类比推理的影响及脑机制。结果发现:(1)行为:不同回避动机强度的消极情绪均会延长类比推理的反应时; 与中性情绪相比,悲伤会提高推理的正确率,而恐惧会降低推理的正确率。(2)脑电:图式提取阶段,N400、P300、LNC被诱发; 类比映射阶段,N400和LNC被诱发,情绪在N400和LNC上的主效应均显著,恐惧情绪下的N400和LNC幅值比悲伤情绪和中性情绪下的更大。研究表明,情绪对类比推理的作用发生在类比映射阶段。恐惧情绪窄化认知,悲伤情绪扩展认知,支持情绪动机维度模型。 相似文献

Bootstrap方法是一种有放回的再抽样方法, 可用于概化理论的方差分量及其变异量估计。用Monte Carlo技术模拟四种分布数据, 分别是正态分布、二项分布、多项分布和偏态分布数据。基于p×i设计, 探讨校正的Bootstrap方法相对于未校正的Bootstrap方法, 是否改善了概化理论估计四种模拟分布数据的方差分量及其变异量。结果表明:跨越四种分布数据, 从整体到局部, 不论是“点估计”还是“变异量”估计, 校正的Bootstrap方法都要优于未校正的Bootstrap方法, 校正的Bootstrap方法改善了概化理论方差分量及其变异量估计。 相似文献

The effects of emotional content of images on recognition memory were studied, bringing together electrophysiological (Event-Related brain Potentials, ERPs) and behavioural (accuracy and speed of recognition, and remember/know judgements) indices. In the study phase, participants assessed 120 images on the scales of valence and arousal. In the test phase, ERPs were recorded while participants viewed again the images, put together with 120 new, and were asked to make old/new decisions and remember/know judgements on them. A clear arousal bias was obtained for remember/know judgements, which revealed that correctly recognised arousing images (negative and positive) received more remember judgements than nonarousing images (neutral and relaxing). Moreover, a Late Positive Component (LPC) activation revealed an old/new effect enhanced by arousing images. The LPC activation was located in parietal areas (precuneus), which appears to be mostly related to successful retrieval based on recollection. The results obtained through different indices supported the emotional bias found in previous studies for arousing material, but do not clarify the effect of the emotional valence on recognition. 相似文献

Belief bias is the tendency to accept conclusions that are compatible with existing beliefs more frequently than those that contradict beliefs. It is one of the most replicated behavioral findings in the reasoning literature. Recently, neuroimaging studies using functional magnetic resonance imaging (fMRI) and event‐related potentials (ERPs) have provided a new perspective and have demonstrated neural correlates of belief bias that have been viewed as supportive of dual‐process theories of belief bias. However, fMRI studies have tended to focus on conclusion processing, while ERPs studies have been concerned with the processing of premises. In the present research, the electrophysiological correlates of cognitive control were studied among 12 subjects using high‐density ERPs. The analysis was focused on the conclusion presentation phase and was limited to normatively sanctioned responses to valid–believable and valid–unbelievable problems. Results showed that when participants gave normatively sanctioned responses to problems where belief and logic conflicted, a more positive ERP deflection was elicited than for normatively sanctioned responses to nonconflict problems. This was observed from ?400 to ?200 ms prior to the correct response being given. The positive component is argued to be analogous to the late positive component (LPC) involved in cognitive control processes. This is consistent with the inhibition of empirically anomalous information when conclusions are unbelievable. These data are important in elucidating the neural correlates of belief bias by providing evidence for electrophysiological correlates of conflict resolution during conclusion processing. Moreover, they are supportive of dual‐process theories of belief bias that propose conflict detection and resolution processes as central to the explanation of belief bias. 相似文献

The paper reviews central concepts and research findings of attachment theory emphasizing its clinical relevance to psychoanalytically informed clinicians. We then turn to a historical analysis in order to understand why Bowlby's work was dismissed within psychoanalytic circles and the reasons why Bowlby's contributions and attachment theory have begun to have a significant impact among clinicians within the last ten years. 相似文献
