A tilted furnished room can induce strong visual reorientation illusions in stationary subjects. Supine subjects may perceive themselves upright when the room is tilted 90 degrees so that the visual polarity axis is kept aligned with the subject. This 'upright illusion' was used to induce roll tilt in a truly horizontal, but perceptually vertical, plane. A semistatic tilt profile was applied, in which the tilt angle gradually changed from 0 degrees to 90 degrees, and vice versa. This method produced larger illusory self-tilt than usually found with static tilt of a visual scene. Ten subjects indicated self-tilt by setting a tactile rod to perceived vertical. Six of them experienced the upright illusion and indicated illusory self-tilt with an average gain of about 0.5. This value is smaller than with true self-tilt (0.8), but comparable to the gain of visually induced self-tilt in erect subjects. Apparently, the contribution of nonvisual cues to gravity was independent of the subject's orientation to gravity itself. It therefore seems that the gain of visually induced self-tilt is smaller because of lacking, rather than conflicting, nonvisual cues. A vector analysis is used to discuss the results in terms of relative sensory weightings. 相似文献

This study investigated the effects of therapist attention on the self-injurious behavior (SIB) of a 6-year-old girl with developmental disabilities. After results of a functional analysis indicated that SIB was maintained by attention and tangible reinforcement, tangible conditions with and without contingent verbal attention were compared. Results suggested that the inclusion of verbal attention in a tangible condition may confound functional analysis outcomes for behavior that is maintained by attention. 相似文献

Anticipation skill in a real-world task: measurement,training, and transfer in tennis 总被引:2,自引:0,他引:2
Williams AM Ward P Knowles JM Smeeton NJ 《Journal of experimental psychology. Applied》2002,8(4):259-270
Anticipation skill in tennis was examined using realistic film simulations, movement-based response measures, and a portable eye movement recording system. Skilled players were faster than their less skilled counterparts in anticipating the direction of opponents' tennis strokes, with this superior performance being based, at least in part, on more effective visual search behaviors. The processes mediating superior performance were then modeled in groups of recreational tennis players using video simulation, instruction, and feedback. Players who received perceptual training improved their performance on laboratory- and field-based tests of anticipation when compared with matched placebo and control groups that did not receive any instruction regarding expert performance strategies. The approach used may have practical utility in a variety of performance contexts. 相似文献

It is well known that sensory events of one modality can influence judgments of sensory events in other modalities. For example, people respond more quickly to a target appearing at the location of a previous cue than to a target appearing at another location, even when the two stimuli are from different modalities. Such cross-modal interactions suggest that involuntary spatial attention mechanisms are not entirely modality-specific. In the present study, event-related brain potentials (ERPs) were recorded to elucidate the neural basis and timing of involuntary, cross-modal spatial attention effects. We found that orienting spatial attention to an irrelevant sound modulates the ERP to a subsequent visual target over modality-specific, extrastriate visual cortex, but only after the initial stages of sensory processing are completed. These findings are consistent with the proposal that involuntary spatial attention orienting to auditory and visual stimuli involves shared, or at least linked, brain mechanisms. 相似文献

In this study, we investigated the treatment utility of the revision of Perry and Viglione's (1991) Rorschach Ego Impairment Index (EII-2) in a sample of 53 child psychiatric inpatients. Parent ratings of symptomatic functioning on the Devereux Scales of Mental Disorders (DSMD; Naglieri, LeBuffe, & Pfeiffer, 1994) were obtained at admission, 30 days postdischarge, and 120 days postdischarge. EII-2 scores correlated with initial symptom elevations on the Critical Pathology at admission. EII-2 scores did not predict short-term response to treatment. However, EII-2 scores demonstrated moderate correlations with long-term outcome and relapse. EII-2 was related to prediction of worsening of symptoms between 30-day and 120-day follow-up as measured by Reliable Change Index scores that were computed for the Externalizing, Internalizing, Critical Pathology, and Total DSMD scales. 相似文献

Participants with schizophrenia (N = 59) were assessed on self-evaluation, symptomatology, and positive and negative affect (expressed emotion) from significant others. An interview-based measure of self-evaluation was used and two independent dimensions of self-esteem were derived: negative and positive evaluation of self. As predicted, negative self-evaluation was strongly associated with positive symptoms, a more critical attitude from family members was associated with greater negative self-evaluation, and analyses supported a model whereby the impact of criticism on patients' positive symptoms was mediated by its association with negative self-evaluation. The interview-based method of self-esteem assessment was found to be superior to the questionnaire because its predictive effects remained after depressed mood was accounted for. 相似文献

Reduction of work-family conflict through the use of selection, optimization, and compensation behaviors 总被引:1,自引:0,他引:1
Prior research has examined both the antecedents to and outcomes of work-family conflict. However, little is known about the existence and efficacy of behavioral strategies that may be used by individuals to reduce the amount of stressors experienced both on the job and at home, which result in work-family conflict. The purpose of this study was to examine the role of selection, optimization, and compensation (SOC) behaviors in relation to both job and family stressors and work-in-family (WIF) conflict and family-in-work (FIW) conflict. Results suggest that the use of general SOC behaviors in both the work and family domains are related to lower amounts of job and family stressors and subsequently lower amounts of WIF conflict and FIW conflict. In general, these results held true even when additional variables (e.g., hours worked, gender, job involvement, family involvement, social support, and supervisor support) were controlled. Implications of these results are discussed. 相似文献

This study documents an unusual case of developmental synaesthesia, in which speech sounds induce an involuntary sensation of taste that is subjectively located in the mouth. JIW shows a highly structured, non-random relationship between particular combinations of phonemes (rather than graphemes) and the resultant taste, and this is influenced by a number of fine-grained phonemic properties (e.g. allophony, phoneme ordering). The synaesthesia is not found for environmental sounds. The synaesthesia, in its current form, is likely to have originated during vocabulary acquisition, since it is guided by learned linguistic and conceptual knowledge. The phonemes that trigger a given taste tend to also appear in the name of the corresponding foodstuff (e.g. /I/, /n/ and /s/ can trigger a taste of mince /mIns/) and there is often a semantic association between the triggering word and taste (e.g. the word blue tastes "inky"). The results suggest that synaesthesia does not simply reflect innate connections from one perceptual system to another, but that it can be mediated and/or influenced by a symbolic/conceptual level of representation. 相似文献

This article explores the phenomenon of self-mutilatory behaviors among practitioners both today and throughout history with the intent of exposing what the author finds to be a radical correlation between mental illness and spirituality. It is the author's belief that today's strong focus on the biology of mental illness, though essential, will extend us only so far in our comprehension of mental pathology; and that an investigation into the spiritual needs of humankind may serve to round out our understanding. 相似文献
