Previous research has shown that emotional stimuli are more likely than neutral stimuli to be selected by attention, indicating that the processing of emotional information is prioritized. In this study, we examined whether the emotional significance of stimuli influences visual processing already at the level of transient storage of incoming information in iconic memory, before attentional selection takes place. We used a typical iconic memory task in which the delay of a poststimulus cue, indicating which of several visual stimuli has to be reported, was varied. Performance decreased rapidly with increasing cue delay, reflecting the fast decay of information stored in iconic memory. However, although neutral stimulus information and emotional stimulus information were initially equally likely to enter iconic memory, the subsequent decay of the initially stored information was slowed for threatening stimuli, a result indicating that fear-relevant information has prolonged availability for read-out from iconic memory. This finding provides the first evidence that emotional significance already facilitates stimulus processing at the stage of iconic memory. 相似文献

Increasing evidence suggests that emotions affect cognitive processes. Recent approaches have also considered the opposite: that cognitive processes might affect people’s mood. Here we show that performing and, to a lesser degree, preparing for a creative thinking task induce systematic mood swings: Divergent thinking led to a more positive mood, whereas convergent thinking had the opposite effect. This pattern suggests that thought processes and mood are systematically related but the type of relationship is process-specific. 相似文献

This paper is based on the observation that side effects, unwanted effects and undesirable developments in psychotherapy are still rarely discussed. Following an attempt to classify the phenomena some instruments which allow their assessment are described. Finally, studies indicating results about the frequency of the individual phenomena and their correlates are summarized. Focusing on side effects and unwanted effects of psychotherapy should start early and persist continuously throughout psychotherapeutic training. 相似文献

Temporal performance parameters vary across the visual field. Their topographical distributions relative to each other and relative to basic visual performance measures and their relative change over the life span are unknown. Our goal was to characterize the topography and age-related change of temporal performance. We acquired visual field maps in 95 healthy participants (age: 10?C90?years): perimetric thresholds, double-pulse resolution (DPR), reaction times (RTs), and letter contrast thresholds. DPR and perimetric thresholds increased with eccentricity and age; the periphery showed a more pronounced age-related increase than the center. RT increased only slightly and uniformly with eccentricity. It remained almost constant up to the age of 60, a marked change occurring only above 80. Overall, age was a poor predictor of functionality. Performance decline could be explained only in part by the aging of the retina and optic media. In Part II, we therefore examine higher visual and cognitive functions. 相似文献

Ideological beliefs have long attracted the attention of social psychologists, who have investigated their genesis as well as their influence on a host of social phenomena. Conservatism, from the Motivated Social Cognition framework, stems from epistemic and existential needs of the individual, and notably the fear of death. However, Terror Management Theory proposes a view of conservatism and its contrary, liberalism, as equivalent cultural worldviews, equally fit to fulfill such needs. In the present contribution, results are presented from five studies, which test the contrasting hypotheses derived from these two perspectives. A new perspective is considered that accounts for these and previous findings. 相似文献

Previous work showed that language has an important function for the development of action control. This study examined the
role of verbal processes for action–effect learning in 4-year-old children. Participants performed an acquisition phase including
a two-choice key-pressing task in which each key press (action) was followed by a particular sound (effect). Children were
instructed to either (1) label their actions along with the corresponding effects, (2) verbalize task-irrelevant words, (3)
or perform without verbalization. In a subsequent test phase, they responded to the same sound effects either under consistent
or under inconsistent sound-key mappings. Evidence for action–effect learning was obtained only if action and effects were
labeled or if no verbalization was performed, but not if children verbalized task-irrelevant labels. Importantly, action–effect
learning was most pronounced when children verbalized the actions and the corresponding effects, suggesting that task-relevant
verbal labeling supports the integration of event representations. 相似文献

Summary Acting on the assumption that pictures affect the processing of sentences only when providing additional information, the authors used pictures, which in an earlier experiment had failed to influence the retention of noun sentences, as illustrations to semantically undefined pronoun sentences, thus establishing a distinct information gradient between sentence and picture. These pronoun sentences were presented to 48 subjects for recall, in four pictorial conditions: without picture, with unambiguous picture, with subject-ambiguous, and with object-ambiguous picture. As hypothesized, picture-less pronoun sentences were more poorly recalled than picture-enriched pronoun sentences. Moreover, sentences accompanied by subject-ambiguous pictures, in which the grammatical subject could not be clearly identified, scored lower than the same sentences with unambiguous or object-ambiguous pictures. The findings invite a communication-theory analysis of the experimental situation, for which Searle's theory of speech acts is invoked.The authors gratefully acknowledge the assistance of Mr. B.
