Unconscious Emotion 总被引:1,自引:0,他引:1
Abstract— Conscious feelings have traditionally been viewed as a central and necessary ingredient of emotion. Here we argue that emotion also can be genuinely unconscious. We describe evidence that positive and negative reactions can be elicited subliminally and remain inaccessible to introspection. Despite the absence of subjective feelings in such cases, subliminally induced affective reactions still influence people's preference judgments and even the amount of beverage they consume. This evidence is consistent with evolutionary considerations suggesting that systems underlying basic affective reactions originated prior to systems for conscious awareness. The idea of unconscious emotion is also supported by evidence from affective neuroscience indicating that subcortical brain systems underlie basic "liking" reactions. More research is needed to clarify the relations and differences between conscious and unconscious emotion, and their underlying mechanisms. However, even under the current state of knowledge, it appears that processes underlying conscious feelings can become decoupled from processes underlying emotional reactions, resulting in genuinely unconscious emotion. 相似文献

Two studies tested whether emotional disclosure increases feelings of closeness toward offenders. In Study 1, participants recalled either someone who had offended them or a neutral acquaintance. "Disclosure" participants then expressed their thoughts and feelings regarding their targets, and "suppression" participants described their targets nonemotionally. As predicted, disclosure increased closeness toward offenders but not toward acquaintances. Study 2 extended these results by including a good friend to test whether disclosure selectively increases closeness toward offenders, and not simply toward any person who evokes strong feelings. This prediction was confirmed. Furthermore, the disclosure effect remained reliable even after controlling for mood. Studies 1 and 2 also showed that closeness toward offenders, but not toward friends or acquaintances, was positively related to the proportion of emotion-related words disclosed. Collectively, these findings suggest that confronting the emotions associated with an offense may be an important first step toward forgiveness. 相似文献

This research tests whether people with high self-esteem are more informed by their emotions than are people with low self-esteem. In Study 1, participants listened to a series of disturbing baby cries, rated how much distress these cries conveyed, and reported their own emotional reactions to the cries. As predicted, the relation between participants' emotional reactions and their cry ratings was strongest at higher levels of self-esteem. In Study 2, self-esteem again determined how strongly participants' own emotional reactions influenced their baby cry ratings, even though esteem was measured weeks before the experiment and even after controlling for social desirability. Study 3 manipulated self-regard and showed that the correlation between participants' emotional reactions and their cry ratings was strong for high-regard participants, moderate for control participants, and weak for low-regard participants. These results suggest that self-esteem serves to validate the informational value of feelings. 相似文献

Human observers demonstrate impressive visual sensitivity to human movement. What defines this sensitivity? If motor experience influences the visual analysis of action, then observers should be most sensitive to their own movements. If view-dependent visual experience determines visual sensitivity to human movement, then observers should be most sensitive to the movements of their friends. To test these predictions, participants viewed sagittal displays of point-light depictions of themselves, their friends, and strangers performing various actions. In actor identification and discrimination tasks, sensitivity to one's own motion was highest. Visual sensitivity to friends', but not strangers', actions was above chance. Performance was action dependent. Control studies yielded chance performance with inverted and static displays, suggesting that form and low-motion cues did not define performance. These results suggest that both motor and visual experience define visual sensitivity to human action. 相似文献

Insect and mammalian olfactory systems are strikingly similar. Therefore, Drosophila can be used as a simple model for olfaction and olfactory learning. The brain of adult Drosophila, however, is still complex. We therefore chose to work on the larva with its yet simpler but adult-like olfactory system and provide evidence for olfactory learning in individually assayed Drosophila larvae. We developed a differential conditioning paradigm in which odorants are paired with positive (“+” fructose) or negative (“-” quinine or sodium chloride) gustatory reinforcers. Test performance of individuals from two treatment conditions is compared—one received odorant A with the positive reinforcer and odorant B with a negative reinforcer (A+/B-); animals from the other treatment condition were trained reciprocally (A-/B+). During test, differences in choice between A and B of individuals having undergone either A+/B- or A-/B+ training therefore indicate associative learning. We provide such evidence for both combinations of reinforcers; this was replicable across repetitions, laboratories, and experimenters. We further show that breaks improve performance, in accord with basic principles of associative learning. The present individual assay will facilitate electrophysiological studies, which necessarily use individuals. As such approaches are established for the larval neuromuscular synapse, but not in adults, an individual larval learning paradigm will serve to link behavioral levels of analysis to synaptic physiology. 相似文献

An electronic classroom with computer workstations and multimedia offers tremendous potential for interactive instruction. To support such instruction, HyperCourseware was developed as an environment and authoring system that recreates on a computer network familiar objects of instruction, such as the syllabus, lecture notes, class rolls, seating charts, exams, and grade lists. In addition, it provides interactive and collaborative tools for group discussion, anonymous feedback, student polling, and shared collaborative workspaces. Applications in statistics and cognitive psychology are discussed along with the specific advantages due to hypermedia links, structure of course materials, integration of parts, and classroom interactivity. Student and faculty evaluations have supported the positive educational benefits of both the electronic classroom and HyperCourseware in general. 相似文献

After receiving a sample shock, subjects in a Threat Condition were told that they would receive additional painful shocks while subjects in a Nonthreat Condition were not threatened with additional shocks. Subjects in an Attentional Diversion Condition were then instructed to read and think about an amusing story, subjects in a Situation Redefinition Condition were instructed to write down reasons why they should not be afraid in this situation, and subjects in a Control Condition were not given any instructions for coping with stress. (Coping Conditions were factorially crossed with Threat Conditions and 192 subjects were employed.) Physiological measures (pulse rate, finger pulse volume, skin resistance) indicated that unlike the results of previous research, attentional diversion was effective in reducing stress but situation redefinition was not. Discussion was focused on the parameters which determine whether or not a coping strategy will be effective. 相似文献

NEURONAL CODING OF SERIAL ORDER: 总被引:3,自引:0,他引:3
Abstract— How does the brain create rule-governed sequences of behavior? An answer to this question may come from a surprising source: the neostriatum (caudate nucleus and putamen), Traditionally, the neostriatum has been considered pun of the brain's motor system, but its contribution to the preparation or execution of movement is recognized generally to concern high-level motor functions. Recent work implicates the neostriatum in disorders of sequential action and thought, as in the repetition of thoughts or habits in human obsessive-compulsive disorder and movements or speech in Tourette's syndrome. Yet there is no direct evidence to support the idea that the neostriatum controls sequences of behavior. Using ethological and neurophysiological techniques to study neural activity in the rat neoslriatum during syntactic grooming sequences, we found that neuronal activity in the anterolateral neostriatum depended on the execution of syntactic sequences of grooming actions. The individual grooming movements themselves did not activate the neoslriatum; activation was determined by the syntactic sequence in which grooming movements were performed. These data provide the first direct evidence that the neoslriatum coordinates the control of rule-governed behavioral sequences. 相似文献
