In an experiment on the effect of intensity accents on the perception of time intervals between tones. H. G. Tekman (2001) found that the regular placement of deviant time intervals in short sequences of tones reduced detection, especially if intensity accents marked the deviant time intervals. That was the opposite of what one wòuld have expected on the basis of the dynamic attending theory of M. R. Jones (1976). The effect might have occurred because temporally deviant tones create cumulative onset shifts that affect all the subsequent tones. If the deviations were randomly placed, then they could follow each other in close succession and change the local tempo. In the present study, the changes of local tempo, which might have acted as a cue for the detection of temporal deviations in the random sequences, were eliminated by compensating for deviant time intervals with equal deviations in the opposite direction in the interval that followed. That change in the stimuli eliminated the negative main effect of regularity, and the accenting interacted with regularity in favor of detection in the regular sequences. However, a simple advantage of regular over random sequences was not observed. The author discusses possible reasons for the lack of a facilitatory effect of regularity. 相似文献

The influences of different action-outcome scenarios on children's evaluative judgments and inferences of outcome intentionality were assessed. One hundred forty-five kindergartners, 2nd graders, and 4th graders heard 4 stories about child actors who engaged in 1 action or 3 equifinal actions and caused a positive or negative outcome. The stories made no mention of the actors' anticipated outcome so that we could assess the children's inferences of whether the actors wanted and had tried to cause the outcome. Children also rated their liking for the actors and the actors' morality. Children's moral and liking judgments were not significantly differentiated by action condition. However, actors who caused positive outcomes received favorable liking and moral judgments, and actors who caused negative outcomes received neutral liking and moral judgments. Children's intentionality inferences varied by the actors' actions and were moderated by outcome valence. The authors discuss children's apparent use of the valence rule when inferring intentionality and their reluctance to judge harshly actors who cause negative outcomes when not privy to the actors' intentions. 相似文献

Children's concepts of various social roles were examined in a task that required the child to indicate the similarity of two occupants of common social roles. Each occupant in the pair was described differently in terms of behaviors appropriate for a particular role. Children in the first, third, and sixth grades were studied. Findings indicated that children in the youngest group held role concepts based primarily on concrete actions, while role concepts of the older two groups were based on more abstract, general role functions. In addition, there is some suggestion that the level of role conceptualization is related to the relevance of the particular role. 相似文献

The author clarifies the objective and essence of the psychological, or perceptual-cognitive, approach to voluntary movement. According to that approach, voluntary movements are organized and performed as meaningful, perceptible events with bodily and environmental aspects. Body-oriented control is thus not neglected in the perceptual-cognitive approach but is actually an important issue. He further clarifies how material and psychological factors relate to each other in motor control and why they are not considered a coalition of constraints. The central importance of the sparse coding principle for the perceptual-cognitive approach is underlined. Finally, the author argues that the psychological information format is particularly suitable for motion control and stresses the power of the perceptual-cognitive approach to possibly provide a unifying framework for understanding human voluntary movements. 相似文献

The authors investigated the relation between hand kinematics and eye movements in 2 variants of a rhythmical Fitts's task in which eye movements were necessary or not necessary. P. M. Fitts's (1954) law held in both conditions with similar slope and marginal differences in hand-kinematic patterns and movement continuity. Movement continuity and eye—hand synchronization were more directly related to movement time than to task index of difficulty. When movement time was decreased to fewer than 350 ms, eye—hand synchronization switched from continuous monitoring to intermittent control. The 1:1 frequency ratio with stable π/6 relative phase changed for 1:3 and 1:5 frequency ratios with less stable phase relations. The authors conclude that eye and hand movements in a rhythmical Fitts's task are dynamically synchronized to produce the best behavioral performance. 相似文献

Attentional requirements of walking at various speeds in older adults were examined. Twenty healthy older adults (69.9?±?2.77?years; 8 males) were asked to walk a distance of 10?m at a self-selected speed as well as 30% quicker and 30% slower. Concurrently, reaction time (RT) was evaluated by having participants respond as fast as possible to randomly presented auditory stimuli. Results reveal that an accelerated walking speed generated faster RT than slow and self-selected speeds, while no difference was found between the latter. Faster RTs during an accelerated walking speed may have been precipitated by the reduced equilibrium demands of the task. 相似文献

Humor appreciation for captioned cartoons was studied as a function of cartoon category and eight predictor variables: complexity, difficulty, fit, depth, visual humor, artwork, vulgarity, and originality. Preference and funniness proved to be virtually identical as criterion variables and were combined as appreciation for further analysis. A nonmetric factor analysis of appreciation ratings yielded four dimensions: (a) Sexual, (b) Incongruity, (c) Social Issues, and (d) Marriage-Family. Sexual and Marriage-Family were the most appreciated categories, Social Issues the least appreciated. Fit and originality were the only predictor variables with significant relationships to appreciation independent of the category effect. Cartoons judged to have the most originality and the best fit between drawing and caption were most appreciated. The results suggest that the kinds of cognitive processes involved in cartoon-humor appreciation are very similar to those involved in environmental preference. 相似文献

AbstractSensory substitution refers to the phenomenon where object and environment information normally acquired through one sense can be obtained by another sense. For example, visual input being provided by hearing or touching. Sensory substitution devices are technological designs that transform the characteristics of one sensory modality into stimuli of another sensory modality. These devices were developed with two purposes: (1) to assist people with sensory disabilities in daily tasks; and (2) to study the involved mechanisms of brain plasticity. This article reviews studies in which sensory substitution phenomenon is employed as a methodological strategy to study visual perception. Furthermore, its use is discussed as an experimental platform to contrast new perceptual theories and underlying neurophysiological mechanisms that are currently under review. 相似文献

This study investigated the multidimensional structure of judgements of emotional appropriateness, the degree to which an observer judges a target's emotion to conform to observer-valued expectations for emotion in that context. Participants (N=169) were shown one of two brief video clips of an actor either showing anger or neutral expressions in an anger-evoking situation of either low, medium, or high severity. Participants rated the target's emotion on the Perception of Emotion Appropriateness Rating Scale (PEARS), which taps observers’ perceptions of a target's emotional appropriateness for a specific situation. We found that appropriateness ratings are comprised of three factors, assessment of Type Present (type of emotion in expression); Type Absent (missing key emotions); and Intensity (intensity with which the emotion is felt or expressed). Results are discussed in terms of the usefulness of a multidimensional conceptualisation of emotional appropriateness. 相似文献

Positive words (e.g., faith) were recognised better when presented in white fonts than in black fonts, whereas the opposite was true for negative words (e.g., enemy). A neural basis for this type of association between emotional valence and brightness was investigated using a visual half-field paradigm. Positive and negative words were presented in black or white fonts and presented to the left visual field–right hemisphere (LVF–RH) or right visual field–left hemisphere (RVF–LH) in a word valence judgement task (i.e., positive vs. negative). A cross-over interaction between emotional valence and brightness was observed; valence judgements were facilitated when a positive word appeared in white and when a negative word appeared in black. This interaction was qualified by a higher-order interaction. The cross-over interaction appeared only for LVF–RH trials, suggesting that the right hemisphere was responsible for the association between emotional valence and brightness. 相似文献
