A temporal gap between fixation point offset and stimulus onset typically yields shorter saccadic latencies to the stimulus than if the fixation stimulus remained on. Several researchers have explored the extent to which this gap also reduces latencies of other responses but have failed to find a gap effect isolated from general warning effects. Experiment 1, however, showed a robust gap effect for aimed hand movements (which required determination of a precise spatial location), regardless of whether the hand moved alone or was accompanied by a saccadic eye movement. Experiment 2 replicated this aimed hand gap effect and also showed a smaller effect for choice manual keypress responses (which required determination of the direction of response only). Experiment 3 showed no gap effect for simple manual keypress responses (which required no spatial determination). The results are consistent with an interpretation of the gap effect in terms of facilitation of spatially oriented responses. 相似文献

‘Mere belongingness to self’ is tested as a sufficient condition for the enhancement of the attractiveness of visual letter stimuli. Experimental evidence is presented that, independent of visual, acoustical, aesthetic, semantic and frequency characteristics, letters belonging to own first and/or family name are preferred above not-own name letters. The effect is obtained in the absence of awareness of the Gestalt of any name, thus challenging current understanding of fundamental affective processes. 相似文献

The authors investigated whether a Simon effect could be observed in an accessory-stimulus Simon task when participants were unaware of the task-irrelevant accessory cue. In Experiment 1A a central visual target was accompanied by a suprathreshold visual lateral cue. A regular Simon effect (i.e., faster cue-response corresponding reaction times [RTs]) was found. Experiment 1B demonstrated that this effect cannot be attributed to perceptual grouping of the target and cue. Experiments 2A, 2B, and 2C showed a reverse Simon effect (i.e., faster noncorresponding RTs) when participants were not aware of the cue. In this condition, the Simon effect would occur relative to the reorientation of attention from the cue, which would initially capture attention, toward the target. This conclusion is supported by the results of Experiments 3A and 3B, in which the reorientation of attention was induced by having the target flash after its onset. With suprathreshold cues either a reverse or regular Simon effect was observed by using a 100-ms or > or = 200-ms onset flashing interval, respectively, whereas with subthreshold cues a reverse Simon effect was found irrespective of the interval length. 相似文献

Jacoby and Whitehouse (1989) reported that masked words can unconsciously bias memory judgments. Others suggest that these results cannot be taken as evidence that words are perceived without awareness, as Jacoby and Whitehouse claimed. In the present experiments, participants' ability to attend to briefly presented context words was manipulated by masking the context words and by an instructional manipulation. In Experiment 1, masked context words increased false recognitions. Different from Jacoby and Whitehouse's results, nonmasked context words showed a similar pattern. In Experiment 2, these effects were replicated and an attended condition was added in which participants read the context words aloud and tried to remember them. False recognition was increased in both masked and unmasked conditions and decreased in the attended condition. These results suggest that the condition for increase or decrease in false recognition is not whether a stimulus is seen or not but whether a stimulus is attended. They suggest that the qualitative difference criterion proposed by Jacoby and Whitehouse is insufficient for determining whether participants are aware of masked presentations. 相似文献

The role of the spatial separation between the ends of a rod and a frame’s inner edge (gap) in modulating the rod-and-frame effect (RFE) has been studied here with frames subtending either large or small retinal angles. With a large frame, rod settings were always in the direction of frame tilt (direct effects) and varied inversely with gap size. With a small frame, rod settings were in the direction of frame tilt for tilts between 7.5° and 15°; with larger frame tilts, rod settings in the direction opposite that of the frame were observed (indirect effects). Increasing gap size produced a tendency toward negativity (away from frame tilt). Consequently, direct effects were larger for small gaps, while the opposite was true for indirect effects. Overall, these results point to the importance of gap size in modulating the RFE, for both large and small displays. 相似文献

The aim of this study was to examine the moderating role of emotional awareness in the relationship between emotion regulation strategies and emotional information processing. A total of 120 female students regulated emotions while watching an unpleasant film. Before and after emotion induction, participants completed a set of tasks that required matching facial expressions. The results demonstrated that participants who were high in emotional awareness showed a significantly smaller increase in error responses (i.e., incorrect matches) than participants who were low in emotional awareness. However, this effect was observed only in suppression (i.e., inhibition of an emotionally expressive behavior), masking (i.e., emotion experienced with a happy expression) and control (i.e., no regulation) conditions. Among reappraisers, who were instructed to adopt a neutral attitude toward the film, regardless of whether they were high or low in emotional awareness, there was not a significant increase in error responses. This study shows that the potentially damaging impact of negative emotions on the processing of emotional information can be prevented by a high emotional awareness or with the implementation of reappraisal as an emotion regulation strategy. 相似文献

Fostering ethical willingness: integrating emotional and contextual awareness with rational analysis
Ethical dilemmas are inherently challenging. By definition, clinicians decide between conflicting principles of welfare and naturally confront competing pulls and inclinations. This investigation of students' responses to an ethical scenario highlights how emotions and concerns can interfere with willingness to implement ethical knowledge. Clear-cut rules are the exception in psychotherapy, and clinicians must judge ethical issues on the basis of the unique context of each case. As such, subjectivity and emotional involvement are essential tools for determining ethical action, but they must be integrated with rational analysis. Strategies for attending to influential emotions and contextual factors in order to mobilize ethical commitment are described. 相似文献

The efficacy of explicit and implicit learning paradigms was examined during the very early stages of learning the perceptual-motor anticipation task of predicting ball direction from temporally occluded footage of soccer penalty kicks. In addition, the effect of instructional condition on point-of-gaze during learning was examined. A significant improvement in horizontal prediction accuracy was observed in the explicit learning group; however, similar improvement was evident in a placebo group who watched footage of soccer matches. Only the explicit learning intervention resulted in changes in eye movement behaviour and increased awareness of relevant postural cues. Results are discussed in terms of methodological and practical issues regarding the employment of implicit perceptual training interventions. 相似文献

Ninety subjects were tested in a single-cue Pavlovian conditioning paradigm involving three groups which differed with regard to the contingency relationship between CS and US (negative contingency, zero contingency, positive contingency). To examine the relationship between conditioned GSR performance and subject’s cognitive beliefs regarding the CS-US relationship, both GSR and CS-US relational learning were constantly measured on a continuous scale over the entire experimental session. The data suggest the independence of autonomic and cognitive responding in the single-cue Pavlovian paradigm. 相似文献

The reduction of saccadic latency by prior offset of the fixation point: an analysis of the gap effect 总被引:13,自引:0,他引:13
The latency to initiate a saccade (saccadic reaction time) to an eccentric target is reduced by extinguishing the fixation stimulus prior to the target onset. Various accounts have attributed this latency reduction (referred to as the gap effect) to facilitated sensory processing, oculomotor readiness, or attentional processes. Two experiments were performed to explore the relative contributions of these factors to the gap effect. Experiment 1 demonstrates that the reduction in saccadic reaction time (RT) produced by fixation point offset is additive with the effect of target luminance. Experiment 2 indicates that the gap effect is specific for saccades directed toward a peripheral target and does not influence saccades directed away from the target (i.e., antisaccades) or choice-manual RT. The results are consistent with an interpretation of the gap effect in terms of facilitated premotor processing in the superior colliculus. 相似文献

The effects of memory for unattended events—for example, events that occur while a person is asleep, anesthetized, or selectively attending to other ongoing events, as in a speech-shadowing task—are rarely revealed in tests of retention that require remembering to be deliberate or intentional. Might such effects become evident in tests that do not demand awareness of remembering? Results of the present shadowing study, involving the recognition and spelling of previously unattended homophones, suggest an affirmative answer to this question. 相似文献

This study prospectively investigated the effects of major life events on subsequent exercise adherence rates of individuals (N = 173) participating in a 2-year, randomized, controlled clinical trial of 3 different exercise conditions (higher-intensity home-based; lower-intensity home-based; and higher-intensity class-based). For 3 of 4 6-month exercise-adherence periods, an analysis of variance indicated a significant main effect (p < .05) for major life events. Compared with participants reporting 0 or 1 major life event, exercise adherence in the maintenance phase was significantly lower for those reporting 3 or 4 major life events regardless of the exercise condition. No significant life-event-exercise-adherence relationship was found in the adoption phase of exercise participation (i.e., Months 1 to 6). The deleterious effect of life events emphasizes the importance of instruction regarding how to prepare for high-risk situations that can lead to missed exercise sessions or to program attrition. 相似文献

The “gap effect” refers to the finding that saccadic latencies are typically reduced when the fixation point is removed just prior to the presentation of a target. One explanation for this effect is that the removal of the fixation point causes the disengagement of covert attention and allows for extremely rapid movements of attention (express attentional shifts). However, previous research regarding express attentional shifts has yielded equivocal results. The present study used a variation of a peripheral cueing paradigm with a discrimination task (Experiment 1) and a detection task (Experiment 2) to further examine this issue. The results from eye movement and keypress latencies indicated that there were express attentional shifts with the discrimination task but not in the detection task. This pattern of results may have been due to differences in how attention was allocated between the two tasks. Thus, evidence for express attentional shifts was found, but only under certain conditions. 相似文献

Artificial intelligence (AI) is an essential strategic element for many industries. Practitioners are exploring ways to incorporate AI into their products, services, and processes, as it transforms everyday life. Recent studies have increasingly examined how consumers respond to various forms of AI robots. This study adds to the existing literature by investigating the factors that drive consumers to adopt AI robots and the underlying psychological processes. Through three studies, we show that consumers' perceived congruence in an AI robot plays an important role in determining their adoption intention for the AI robot. We further demonstrate that such a perception of congruence is jointly determined by the AI robot's benefit type and appearance familiarity. The findings suggest that consumers are more inclined to adopt an AI robot when they are designed to provide hedonic benefits and resembles real-life objects. By contrast, an AI robot designed for utilitarian benefits are more likely to be adopted when it has the appearance of a machine. In addition, we show that perception of fit mediates this joint effect. Furthermore, we show that the effect of congruence perception on adoption intention is attenuated when consumers have a higher level of dialectical thinking. This study discusses both the theoretical and practical implications. 相似文献

Conventional Bayesian analysis for proportions is not appropriate for proportions with a background effect, for example, for the proportion of correct responses in a sensory difference test using a forced‐choice method with a guessing probability. The main difficulty is that it is not reasonable to assume that a proportion with a background effect has a beta prior distribution. A generalized posterior distribution for proportions is derived in this paper. It includes the standard beta posterior distribution for a proportion without background effect as a special case. Bayesian inference and Bayesian sample size determination for proportions based on the generalized posterior distribution are discussed. 相似文献

Participants provided information about their childhood by rating their confidence about whether they had experienced various
events (e.g., “broke a window playing ball”). On some trials, participants unscrambled a key word from the event phrase (e.g.,
wdinwo—window) or an unrelated word (e.g., gnutge—nugget) before seeing the event and giving their confidence ratings. The act of unscrambling led participants to increase their
confidence that the event occurred in their childhood, but only when the confidence rating immediately followed the act of
unscrambling. This increase in confidence mirrors the “revelation effect” observed in word recognition experiments. In the
present article, we analyzed our data using a new signal detection mixture distribution model that does not require the researcher
to know the veracity of memory judgments a priori. Our analysis reveals that unscrambling a key word or an unrelated word
affects response bias and discriminability in autobiographical memory tests in ways that are very similar to those that have
been previously found for word recognition tasks. 相似文献

According to theories of embodiment enacting a smile or a frown can positively or negatively influence one’s evaluations, even without awareness of one’s facial activity. While some previous studies found evidence for facial feedback effects, recent replication attempts could not confirm these findings. Are our decisions throughout the day amenable to the state of our facial muscles? We tested the effect of smiling and frowning on the evaluation of emotional sentences describing everyday situations. While most previous studies based their assessment of awareness on verbal debriefing interviews without explicitly defined criteria, we employed a written debriefing questionnaire in order to avoid potential bias when identifying participants’ awareness. Our results indicate that smiling/frowning increased/decreased sentence ratings only for participants aware of their expressions. This emphasizes the importance of more rigorous awareness tests in facial feedback studies. Our results support the view that facial feedback cannot necessarily influence us without conscious mediation. 相似文献
