The relationship between eye movements and spatial attention 总被引:8,自引:0,他引:8
Martin Shepherd John M. Findlay Robert J. Hockey 《The Quarterly Journal of Experimental Psychology Section A: Human Experimental Psychology》1986,38(3):475-491
Most previous studies of the attentional consequences of making saccadic eye movements have used peripheral stimuli to elicit eye movements. It is argued that in the light of evidence showing automatic “capture” of attention by peripheral stimuli, these experiments do not distinguish between attentional effects due to peripheral stimuli and those due to eye movements. In the present study, spatial attention was manipulated by varying the probability that peripheral probe stimuli would appear in different positions, while saccades were directed by a central arrow, enabling the effects of attention and eye movements to be separated. The results showed that the time to react to a peripheral stimulus could be shortened both by advance knowledge of its likely position and, separately, by preparing to make a saccade to that position. When the saccade was directed away from the most likely position of the probe, the targets for attention and eye movements were on opposite sides of the display. In this condition, the effects of preparing to make a saccade proved to be stronger than the effects of attentional allocation until well after the saccade had finished, suggesting that making a saccade necessarily involves the allocation of attention to the target position. The effects of probe stimuli on saccade latencies were also examined: probe stimuli that appeared before the saccade shortened saccade latencies if they appeared at the saccade target, and lengthened saccade latencies if they appeared on the opposite side of fixation. These facilitatory and inhibitory effects were shown to occur at different stages of saccade preparation and suggest that attention plays an important role in the generation of voluntary eye movements. The results of this study indicate that while it is possible to make attention movements without making corresponding eye movements, it is not possible to make an eye movement (in the absence of peripheral stimulation) without making a corresponding shift in the focus of attention. 相似文献

The need to train accurate, not necessarily agreeing, observers is discussed. Intraobserver consistency as an intermediate criterion in such training is proposed and contrasted with the more familiar criterion of interobserver agreement. Videotaped observations of social interactions between handicapped and nonhandicapped preschoolers provided the medium for examining the criterion agreement of four observers trained against each type of standard. Observers generally failed to show high levels of criterion agreement whether trained to a within- or to a between-observer agreement standard. The results varied somewhat with the frequency of behaviors, however. Correlations between interobserver agreement and intraobserver consistency were variable but somewhat higher when interobserver agreement was the training criterion than when intraobserver consistency was the criterion. Correlations between interobserver agreement and criterion agreement ranged from — .16 to .89 during interobserver agreement training. Correlations between intraobserver consistency and criterion agreement ranged from — .23 to .99 during intraobserver consistency training. 相似文献

The implications of sociobiology for comparative psychology are discussed. First, the following preliminary topics are considered:
(a) the historical origins of sociobiology, and (b) the general criticisms leveled at this field. Second, the characteristics
of the evolutionary functional approach to animal behavior are outlined: (a) the individual focus of natural selection, with
its associated implications for the evolution of altruism, and (b) the use of mathematical models, notably optimality and
games theory models. Third, it is suggested that the evolutionary functional approach can enrich the study of comparative
psychology in the following ways: (a) by providing a broad framework for interspecific comparisons based on the principle
of natural selection, and (b) by aiding the study of motivation and learning mechanisms through focusing attention on the
function of such mechanisms. 相似文献

Brief presentations of letter arrays were probed by bar markers within or outside the fovea after various time delays. Figural
information presented to the foveal region was retained better under a photopic condition than information in the parafoveal
region, but under a scotopic condition parafoveal information demonstrated superior retention. However, decay rates over time
of all functions were similar, demonstrating that figural information in the rods and cones decays at similar rates. 相似文献

Since the 1970s, investigative profilers at the FBI's Behavioral Science Unit (now part of the National Center for the Analysis of Violent Crime) have been assisting local, state, and federal agencies in narrowing investigations by providing criminal personality profiles. An attempt is now being made to describe this criminal-profile-generating process. A series of five overlapping stages lead to the sixth stage, or the goal of apprehension of the offender: (1) profiling inputs, (2) decision-process models, (3) crime assessment, (4) the criminal profile, (5) investigation, and (6) apprehension. Two key feedback filters in the process are: (a) achieving congruence with the evidence, with decision models, and with investigation recommendations, and (b) the addition of new evidence. 相似文献

Early and late in 18 2-day solo-led psychodynamic groups for mental health professionals, 185 participants rated their own behavior and each other's on composite measures of Acceptance versus Rejection of Self (ARS) and of Others (ARO). Only on ARO were leaders consistently rated more favorably than members. Considered by group units, members' mean ratings of peers made modest but significant early-to-late advances on both measures. About two-thirds of all intergroup differences in members' net shifts were separately predictable from ratings of leaders by self and also by pooled group members each time. Groups' ARO shifts were best predicted by members' ratings of leaders toward Warm versus Cold. Leader self-ratings toward Accepts others versus Rejects others best predicted groups' ARS shifts. Featuring interpersonal behavior's two principal dimensions and bridging the common split between studies of group outcome versus group processes, these findings generally support Roger's (1959) theory of personality change. 相似文献

Homosexuals, bisexuals, and heterosexuals were compared on self-reported love preferences and ideals. In general, the three groups tended to agree on ideal characteristics of love objects, love relationships, and love related beliefs. Nevertheless, the groups differed significantly on preferences and beliefs related to love-object sex, residential proximity, ethnic background, physical intimacy, freedom from feelings of jealousy, sexual fidelity, emotional intimacy, and the importance of religious or legal acknowledgment.An early version of this paper was presented at the Annual Meeting of the National Council on Family Relations, in San Francisco, October 1984, Journal Series No. 2973 of the Hawaii Institute of Tropical Agriculture and Human Resources. 相似文献
