The current study investigated the effects of presentation time and fixation to expression-specific diagnostic features on emotion discrimination performance, in a backward masking task. While no differences were found when stimuli were presented for 16.67 ms, differences between facial emotions emerged beyond the happy-superiority effect at presentation times as early as 50 ms. Happy expressions were best discriminated, followed by neutral and disgusted, then surprised, and finally fearful expressions presented for 50 and 100 ms. While performance was not improved by the use of expression-specific diagnostic facial features, performance increased with presentation time for all emotions. Results support the idea of an integration of facial features (holistic processing) varying as a function of emotion and presentation time. 相似文献

We investigated the effects of smiling on perceptions of positive, neutral and negative verbal statements. Participants viewed computer-generated movies of female characters who made angry, disgusted, happy or neutral statements and then showed either one of two temporal forms of smile (slow vs. fast onset) or a neutral expression. Smiles significantly increased the perceived positivity of the message by making negative statements appear less negative and neutral statements appear more positive. However, these smiles led the character to be seen as less genuine than when she showed a neutral expression. Disgust + smile messages led to higher judged happiness than did anger + smile messages, suggesting that smiles were seen as reflecting humour when combined with disgust statements, but as masking negative affect when combined with anger statements. These findings provide insights into the ways that smiles moderate the impact of verbal statements. 相似文献

Previous meta-analyses support a female advantage in decoding non-verbal emotion (Hall, 1978, 1984), yet the mechanisms underlying this advantage are not understood. The present study examined whether the female advantage is related to greater female attention to the eyes. Eye-tracking techniques were used to measure attention to the eyes in 19 males and 20 females during a facial expression recognition task. Women were faster and more accurate in their expression recognition compared with men, and women looked more at the eyes than men. Positive relationships were observed between dwell time and number of fixations to the eyes and both accuracy of facial expression recognition and speed of facial expression recognition. These results support the hypothesis that the female advantage in facial expression recognition is related to greater female attention to the eyes. 相似文献

The present study integrated three different measures of emotional empathic behavior in a social context: verbal self‐report measures (empathic response, emotional involvement, emotional significance, and valence), facial mimicry (activity of corrugator and zygomaticus muscles), and personal response to the Balanced Emotional Empathy Scale (BEES). Participants were presented with different interpersonal scene types (cooperation, noncooperation, conflict, indifference). Firstly, self‐rating on empathy, emotional involvement, and valence varied as a function of interpersonal context. Secondly, corrugator activity increased in response to conflictual and noncooperative situations; zygomatic activity increased in response to cooperative situations. Third, high‐ and low‐BEES subjects showed different empathic behavior: High‐empathic subjects were more responsive to empathy‐related situations than low‐empathic subjects. The convergence and divergence of these multidimensional measures was discussed. 相似文献

The phenomenon referred to as illusory line-motion (ILM; O. Hikosaka, S. Miyauchi, & S. Shimojo, 1993a) has been described as a measure of the local facilitation of attention gradient. However, J. Kawahara, K. Yokosawa, S. Nishida, and T. Sato (1996) have demonstrated a spatially parallel search for an “odd man out” in the ILM direction. Apart from showing preattentive ILM perception in terms of an analogy between line-motion and apparent motion, the authors examined whether ILM perception is possible without attention from another point of view. Four experiments revealed that the ILM target can be detected in parallel without invoking attentional facilitation and invalidated the possible contribution of attentional set in parallel ILM search. Participants were able to correctly detect the ILM target among multiple nontargets, even when the line orientation was changed from trial to trial. The authors' independent-detection model predicted ILM search performance well on several occasions. These findings strongly support a preattentive and stimulus-driven explanation of ILM perception. 相似文献

ABSTRACTPrevious research has shown that stimuli in which a moving object (A) contacts a stationary one (B) and stops, and object B then moves off in the same direction, give rise to a causal impression: object A is perceived as producing the motion of object B. This impression is weakened or does not occur if there is a delay between A contacting B and B moving, or if there is a spatial gap between B and the location at which A stops. It is shown that a strong causal impression can occur despite the presence of both gap and delay if there are cues to generative transmission of causal influence from A to B. The cues investigated were successive colour change of a series of objects filling the gap between A and B. Reported causal impressions were stronger with the colour change stimuli than with stimuli in which the objects were present but did not change colour, and stronger if the colour change proceeded from A to B than if it proceeded in the opposite direction. Reported causal impressions increased in strength as the number of objects involved in the colour change increased, consistent with the hypothesis that the colour change is a cue to a process of transmission, and inconsistent with the hypothesis that it is perceived or inferred as involving a chain of causal relations. Other kinds of changes to object properties—a small upward motion, shrinkage without moving, and disappearance—yielded similar results. It appears that any rapid sequential change in object properties in the direction of causal influence can function to give rise to the visual impression of generative transmission. The possible role of apparent motion is discussed. 相似文献

With over a century of theoretical developments and empirical investigation in broad fields (e.g., anthropology, psychology, evolutionary biology), the universality of facial expressions of emotion remains a central debate in psychology. How near or far, then, is this debate from being resolved? Here, I will address this question by highlighting and synthesizing the significant advances in the field that have elevated knowledge of facial expression recognition across cultures. Specifically, I will discuss the impact of early major theoretical and empirical contributions in parallel fields and their later integration in modern research. With illustrative examples, I will show that the debate on the universality of facial expressions has arrived at a new juncture and faces a new generation of exciting questions. 相似文献

Recent studies have shown that reaction times to expressions of anger with averted gaze and fear with direct gaze appear slower than those to direct anger and averted fear. Such findings have been explained by appealing to the notion of gaze/expression congruence with aversion (avoidance) associated with fear, whereas directness (approach) is associated with anger. The current study examined reactions to briefly presented direct and averted faces displaying expressions of fear and anger. Participants were shown four blocked series of faces; each block contained an equal mix of two facial expressions (neutral plus either fear or anger) presented at one viewpoint (either full face or three quarter leftward facing). Participants were instructed to make rapid responses classifying the expressions as either neutral or expressive. Initial analysis of reaction time distributions showed differences in distribution shape with reactions to averted anger and direct fear showing greater skew than those to direct anger and averted fear. Computational modelling, using a diffusion model of decision making and reaction time, showed a difference in the rate of information accrual with more rapid rates of accrual when viewpoint and expression were congruent. This analysis supports the notion of signal congruence as a mechanism through which gaze and viewpoint affect our responses to facial expressions. 相似文献

We demonstrated that vection is induced by a motion stimuli that does not have an explicit, bottom‐up motion component. The stimulus motion used in this experiment was animation movie clips of walking people, with no positional changes within the stimulus field. There were no low‐level motion signals in the direction of gait. The results indicate that strong vection was observed under optimal stimuli conditions, that is, large visual field and multiple walkers. These results suggest that vection can be elicited solely by motion signals extracted at relatively higher levels within the visual system. This is the first report that a pure high‐level motion related to “implied motion” induces vection. 相似文献

The interaction of acoustic waves with dislocations leads to aperiodic oscillations in the magnitude of the acoustic nonlinearity parameter β as a function of the acoustic drive amplitude σ ampl. The magnitude and spacing of the oscillations depend on the value of the Peierls stress. A least-square curve fit of the β(σ ampl) equation to experimental data taken of 99.999% pure aluminum monocrystals oriented for wave propagation along the [1?0?0] crystal axis yields the value 6.2?×?104?Pa for the Peierls stress. The value is consistent with the smallest values reported in the literature for aluminum where for both theoretical and experimental studies the reported values range over three orders of magnitude. 相似文献
