We investigated whether emotional information from facial expression and hand movement quality was integrated when identifying the expression of a compound stimulus showing a static facial expression combined with emotionally expressive dynamic manual actions. The emotions (happiness, neutrality, and anger) expressed by the face and hands were either congruent or incongruent. In Experiment 1, the participants judged whether the stimulus person was happy, neutral, or angry. Judgments were mainly based on the facial expressions, but were affected by manual expressions to some extent. In Experiment 2, the participants were instructed to base their judgment on the facial expression only. An effect of hand movement expressive quality was observed for happy facial expressions. The results conform with the proposal that perception of facial expressions of emotions can be affected by the expressive qualities of hand movements. 相似文献

An affective priming paradigm with pictures of environmental scenes and facial expressions as primes and targets, respectively,
was employed in order to investigate the role of natural (e.g., vegetation) and built elements (e.g., buildings) in eliciting
rapid affective responses. In Experiment 1, images of environmental scenes were digitally manipulated to make continua of priming pictures with a gradual increase of
natural elements (and a decrease of built elements). The primes were followed by presentations of facial expressions of happiness
and disgust as to-be-recognized target stimuli. The recognition times of happy faces decreased and the recognition times of
disgusted faces increased as the quantity of natural/built material present in the primes increased/decreased. The physical
changes also influenced the evaluated restorativeness and affective valence of the primes. In Experiment 2, the primes used in Experiment 1 were manipulated in such a way that they were void of any recognizable natural or built elements but contained either similar
colours or similar shapes as primes in Experiment 1. This time the results showed no effect of priming. These results were interpreted to give support for a view that the priming
effect by environmental pictures is due to the primes representing environmental scenes and not due to the presence of certain
low-level colour or shape information in the primes. In all, the present results provide evidence that perception of environmental
scenes elicits automatic affective responses and influences recognition of facial expressions. 相似文献

Previous choice reaction time studies have provided consistent evidence for faster recognition of positive (e.g., happy) than negative (e.g., disgusted) facial expressions. A predominance of positive emotions in normal contexts may partly explain this effect. The present study used pleasant and unpleasant odors to test whether emotional context affects the happy face advantage. Results from 2 experiments indicated that happiness was recognized faster than disgust in a pleasant context, but this advantage disappeared in an unpleasant context because of the slow recognition of happy faces. Odors may modulate the functioning of those emotion-related brain structures that participate in the formation of the perceptual representations of the facial expressions and in the generation of the conceptual knowledge associated with the signaled emotion. 相似文献

Happy faces involve appearance changes in the mouth (the smile) and eye region (e.g., narrowing of the eye opening). The present experiments investigated whether the recognition of happy faces is achieved on the basis of the smile alone or whether information in the eye region is also used. A go/no-go task was used in which participants responded to happy faces and withhold a response to nonhappy distractors. The presence/absence of the expressive cues in the eyes did not affect recognition accuracy but reaction times were slightly longer for smiles without expressive cues in the eyes. This delay was not obtained when the top and the bottom halves of the faces were misaligned, or when the distractor was changed from a top-dominant to a bottom-dominant facial expression (i.e., from anger to disgust). Together, these results suggest that the eyes may have a modest effect on speeded recognition of happy faces although the presence of this effect may depend on task context. 相似文献
