The Component Process Model posits that attention is appraisal-driven rather than stimulus-driven and that the appraisal of relevance is of critical importance in such a mechanism. This means that any stimulus can attract attention or not depending on how relevant it is appraised. This hypothesis was tested in an implicit border similarity judgement task, in which thirsty participants were presented with bottles and vases that were respectively very relevant and weakly relevant to their goal to quench their thirst. These stimuli were also presented to quenched participants for whom none of the stimuli was relevant. The findings support the idea that our attention is more likely to be appraisal-driven than stimulus-driven, since bottles produced an attentional interference in thirsty participants only. It was also observed that, even if vases were judged weakly relevant by thirsty participants, they produced an attentional interference compared to empty stimuli, which was not the case in the quenched participants group. The concept of goal relatedness was proposed as an explanation for this result, and methodological implications were also discussed.  相似文献

Appropriate visual behaviour is necessary for safe driving. Many previous studies have found that when performing non-visual cognitive tasks, drivers typically display an increased amount of on-path glances, along with a deteriorated visual scanning pattern towards potential hazards at locations outside their future travel path (off-path locations). This is often referred to as a gaze concentration effect. However, what has not been explored is more precisely how and when gaze concentration arises in relation to the cognitive task, and to what extent the timing of glances towards traffic-situation relevant off-path locations is affected. To investigate these specific topics, a driving simulator study was carried out. Car drivers’ visual behaviour during execution of a cognitive task (n-back) was studied during two traffic scenarios; one when driving through an intersection and one when passing a hidden exit. Aside from the expected gaze concentration effect, several novel findings that may explain this effect were observed. It was found that gaze shifts from an on-path to an off-path location were inhibited during increased cognitive load. However, gaze shifts in the other direction, that is, from an off-path to an on-path location, remained unaffected. This resulted in on-path glances increasing in duration, while off-path glances decreased in number. Furthermore, the inhibited off-path glances were typically not compensated for later. That is, off-path glances were cancelled, not delayed. This was the case both in relation to the cognitive task (near-term) and the traffic environment (far-term). There was thus a general reduction in the number of glances towards situationally relevant off-path locations, but the timing of the remaining glances was unaffected. These findings provide a deeper understanding of the mechanism behind gaze concentration and can contribute to both understanding and prediction of safety relevant effects of cognitive load in car drivers.  相似文献

In a spatial cueing paradigm it was investigated whether endogenous orienting is sensitive to orienting processes in the previous trial. Specifically, the effect of the previous cue direction, the previous trial type (valid, invalid, neutral, catch) and target alternation effects were studied. Strategic effects were shown as attentional costs and benefits were larger after a valid than after an invalid trial. Following catch trials, an overall response slowing was observed, but costs and benefits were unaffected. This was interpreted as a reduction in alertness and as support for the dissociation between spatial and temporal attentional mechanisms. Repetition of target position per se had no effect, but in neutral trials responses were slower to targets appearing at the location that was cued in the previous trial, independent of validity of the preceding trial. This suggests that long-term inhibition-of-return can occur between trials when attention is controlled endogenously.  相似文献

Two pre-posttest controlled group experiments were conducted to examine the efficacy of self-instructional training as a method to reduce children's dental fears. In the first experiment 30 dentally fearful children between the ages of 8 and 12 were assigned to one of three experimental conditions: training in threat-related verbal coping responses, training in competence-related verbal coping responses, an emotive imagery procedure, or to one of two control conditions: a placebo-or a no-treatment control group. Results indicate a significant anxiety reduction across all groups. No difference was found between groups. This result was attributed to an habituation effect due to exposure-in-vivo at pretest. In a second experiment, 29 highly fearful children were assigned to a competence-related self-speech group, an emotive-imagery or a no-treatment control group. This time no anxiety reduction was found. Combined with other studies, the present results raise critical questions regarding the potential efficacy of self-instructional training as a method to reduce serious fears in children.  相似文献

The present study examined whether articulatory suppression influences homophone effects in semantic access tasks using Japanese kanji words. In Experiment 1, participants were required to decide whether visually presented word pairs were synonyms. This experiment replicated the homophone effect observed in previous research that showed more false positive errors in response to nonsynonym homophone pairs than to controls. The present study found that this homophone effect was also obtained under an articulatory suppression condition. In Experiment 2, participants performed a semantic decision task, in which they had to judge whether a visually presented target word was an exemplar of a definition that was shown immediately before presentation of the target word. The homophone effect observed in previous studies was replicated—that is, longer response times and more false positive errors were associated with homophones of correct exemplars than with nonhomophone control words. This homophone effect was also obtained under an articulatory suppression conditions. These results suggest that the phonological processing that produces the homophone effects in semantic access tasks using Japanese kanji words does not include articulatory mechanisms.  相似文献

This study followed from an earlier case study in which an agoraphobic client was treated daily for a period of four weeks by in vivo exposure. Ratings of his perceived anxiety responses in the behavioural, cognitive, and physiological systems were monitored throughout treatment. Concordance between these ratings was associated with positive outcome. This study was an attempt to replicate some of these findings. A group programme involving four sessions in which clients were taught anxiety management skills, exposed in imagination to situations relating, to dentistry, and given homework assignments was carried out with clients presenting with disproportionate dental anxiety. The subjects were obtained by means of local newspaper and radio advertisements and randomly assigned to a massed or spaced treatment condition. It was predicted that the massed condition involving shorter intersession intervals would be superior at producing habituation and concordance than the spaced condition. The results failed to show differences between the massed and spaced treatment condition with regard to concordance and outcome. However, it was confirmed, once more, that concordance between the three modes of anxiety responding was positively related to outcome.  相似文献

Hood recently reported that preschool children overgeneralized the prediction that falling objects travel in a straight line in spite of extensive counter‐evidence that the object had been deviated to a non‐aligned box by a tube. This behaviour was interpreted as a na?^ve theory of gravity resulting from an overgeneralization derived from experience of falling objects. The current study set out to test whether there was also a significant tendency for 2‐year‐olds to predict that objects travel in a straight line in the horizontal plane. This was achieved by comparing search for an invisibly displaced object moving either vertically or horizontally. The findings confirmed a gravity bias for falling events but did not reveal a similar tendency in the horizontal condition. In the horizontal task, children were as likely to search at an incorrect non‐aligned box as an aligned incorrect box. This supports the interpretation of a na?^ve gravity bias present from at least 2 years of age.  相似文献

A double-blind trial with pyrithioxine was made with 22 pairs of visually handicapped children who were equal in IQ scores and in chronological age. Although an improvement of abstraction ability was noticed, the overall results were not in concurrence with the general tendency in relevant literature.This paper is an abstract from a master's thesis in psychology submitted to the University of Stellenbosch.  相似文献

This study utilised an instrumental case study to investigate the experience of a woman living in poverty in a South African community. The participant was a widowed African female with two children. Data were collected during an interview process that took place over a period of ten weeks. Each interview was in-depth and lasted between forty minutes and an hour long. Appreciative Inquiry (AI) was used to facilitate the construction of the interview questions. Data were thematically analyzed. Findings suggest that AI leads to a positive view of self and others even in the context of significant poverty.  相似文献

This article presents a new test of a principle of decision making calleddynamic consistency. This principle was tested in an experiment in which participants were asked to make decisions about a second gamble within a sequence of two gambles. Participants were first asked to make a planned choice about the second gamble. The planned choice was madebefore the first gamble was played and was conditioned on the anticipated outcomes of the first gamble.After the first gamble was played, the same participants were asked to make a final choice about the second gamble, conditioned on the experienced outcome of the first gamble. The results showed that participants’ final choices were frequently inconsistent with their plans, even when the anticipated and experienced outcomes were identical. These inconsistencies occurred in a systematic direction. Experiencing an anticipated gain resulted with a change toward risk aversion, and experiencing an anticipated loss resulted in a change toward risk seeking. These results are explained in terms of the effect of actual experience on the reference point used for the evaluation of the decision problem.  相似文献

Two experiments report the effects of generating a concurrent position expectancy and form expectancy. Ss were precued to a stimulus position where 1 target shape was most probable, and they made a speeded 2-choice response to the orientation of the displayed shape. Response time (RT) was faster for an expected position than an unexpected position and faster for a likely shape than for an unlikely shape. This replicates the work of Lambert and Hockey (1986). It was also observed, however, that when a stimulus appeared at an unexpected position where 2 shapes were equally improbable, RT was slower for the shape that had been likely rather than unlikely at the cued position. This finding is incompatible with the probability-matching hypothesis of Lambert and Hockey. The data support a hierarchical-expectancy model of attentional selectivity.  相似文献

A review of the psychoanalytic literature shows that empathy has always played an important part in the practice of psychoanalysis, but that as a concept it has not been well understood. This confusion and a certain mistrust of empathy that it engenders were traced to an incomplete understanding of the meaning of the term, and to the lack of an affect theory that could explain the communication involved in the empathic process. These problems were examined and suggestions for their resolution were made. A line of affective development that culminated in empathic understanding was proposed. An operational approach to empathy was described and the role of empathy as the basis for and the prelude to psychoanalytic interpretation was discussed.  相似文献

This study was designed to examine the characteristics of a sexual harassment schema and its consequences using expectancy-violation theory as a framework for investigating an ostensible organizational grievance. Reactions to sexual harassment complainants were expected to be less favorable when the complainant was male than when the complainant was female. Results for the complainants of sexual harassment confirmed that men were believed less, liked less, and punished more than women. Furthermore, the tendency to believe and like female complainants more than male complainants was stronger when complainants were physically attractive. This study contributes to a growing body of research on gender schemas in the context of sexual harassment.  相似文献

This research demonstrated some of the conditions under which retarded children can be taught to imitate the actions of adults. Before the experiment, the subjects were without spontaneous imitative behavior, either vocal or motor. Each subject was taught, with food as reinforcement, a series of responses identical to responses demonstrated by an experimenter; i.e., each response was reinforced only if it was identical to a prior demonstration by an experimenter. Initially, intensive shaping was required to establish matching responses by the subjects. In the course of acquiring a variety of such responses, the subjects' probability of immediate imitation of each new demonstration, before direct training, greatly increased. Later in the study, certain new imitations, even though perfect, were never reinforced; yet as long as some imitative responses were reinforced, all remained at high strength. This imitativeness was then used to establish initial verbal repertoires in two subjects.  相似文献

One hundred adolescent cases admitted to an in-patient unit were studied to determine how often conjoint family therapy was used. Although the explicit policy of the ward was to use this form of treatment in all cases, in fact only fifty per cent were so treated. This paper reviews the possible explanations for this.  相似文献

Simon effects refer to the finding that choice-response latencies to a nonspatial aspect of a stimulus vary depending on the spatial correspondence between the stimulus position and the position of the correct response alternative. Recently, researchers have proposed an attention-coding account of Simon effects whereby the (irrelevant) stimulus spatial code involved in the generation of the effect is formed in the process of attentional orienting to the stimulus. This account predicts that if attentional orienting is unnecessary at stimulus onset, as when the stimulus appears at an attended location, Simon effects will not be observed. This prediction was tested by measurement of Simon effects in an attention-precuing task in which the stimulus was presented at attended and unattended locations. Significant Simon effects were observed independently of the focus of attention. This result was obtained over a large range of precue-target SOAs, and did not depend on whether central or peripheral precues were used to direct attention or on whether the relevant target dimension was color or form. Significant Simon effects were not observed when the precue-target SOA was 50 ms, irrespective of the other precue and task conditions. The data do not support the prediction of the attention-coding account and thus question the generality of the account in its current form. It is suggested that spatial and temporal uncertainties are important factors that influence the pattern of results, and that these factors must be incorporated into attention-coding models of the Simon effect.  相似文献

Faces may be difficult to recognize in photographic negative simply because they contain a large range of grays, while printed words and geometric shapes, which contain no grays, are easy to recognize in negative. This explanation was partly tested in an experiment where Ss had to recognize positive and negative pictures of well-known people, both using normal monochrome photographs and using lith photographs in which all areas of gray were removed. Lith photographs were harder to recognize than normal photographs, but the difference between positive and negative was the same for lith pictures as for normal ones. This does not rule out an explanation in terms of grays, but it does put a major constraint on it.  相似文献
