The effect of contextual information on the resolution of ambiguity was investigated in a group of individuals awaiting dental treatment and a group of control individuals. Participants heard threat/neutral, neutral/neutral and positive/neutral homophones while being simultaneously presented with a context word that was consistent with one of the two meanings of the homophone. Participants then made a lexical decision task on a target word that was one of the two alternate spellings of the homophone. We found that the dental group (...) was more sensitive to context for all types of homophones, and there was no evidence for mood congruency. It also appeared that there might have been an element of mood regulation in the dental group, as they were slower to respond to the emotional targets overall. Our results show that sensitivity to context in state anxiety is a robust phenomenon and one that generalises to naturally occurring anxious moods. (shrink)

Many research fields concerned with the processing of information contained in human faces would benefit from face stimulus sets in which specific facial characteristics are systematically varied while other important picture characteristics are kept constant. Specifically, a face database in which displayed expressions, gaze direction, and head orientation are parametrically varied in a complete factorial design would be highly useful in many research domains. Furthermore, these stimuli should be standardised in several important, technical aspects. The present article presents the freely (...) available Radboud Faces Database offering such a stimulus set, containing both Caucasian adult and children images. This face database is described both procedurally and in terms of content, and a validation study concerning its most important characteristics is presented. In the validation study, all frontal images were rated with respect to the shown facial expression, intensity of expression, clarity of expression, genuineness of expression, attractiveness, and valence. The results show very high recognition of the intended facial expressions. (shrink)

Face perception, perhaps the most highly developed visual skill in humans, is mediated by a distributed neural system in humans that is comprised of multiple, bilateral regions. We propose a model for the organization of this system that emphasizes a distinction between the representation of invariant and changeable aspects of faces. The representation of invariant aspects of faces underlies the recognition of individuals, whereas the representation of changeable aspects of faces, such as eye gaze, expression, and lip movement, underlies the (...) perception of information that facilitates social communication. The model is also hierarchical insofar as it is divided into a core system and an extended system. The core system is comprised of occipitotemporal regions in extrastriate visual cortex that mediate the visual analysis of faces. In the core system, the representation of invariant aspects is mediated more by the face-responsive region in the fusiform gyrus, whereas the representation of changeable aspects is mediated more by the face-responsive region in the superior temporal sulcus. The extended system is comprised of regions from neural systems for other cognitive functions that can be recruited to act in concert with the regions in the core system to extract meaning from faces.

With a few yet increasing number of exceptions, the cognitive sciences enthusiastically endorsed the idea that there are basic facial expressions of emotions that are created by specific configurations of facial muscles. We review evidence that suggests an inherent role for context in emotion perception. Context does not merely change emotion perception at the edges; it leads to radical categorical changes. The reviewed findings suggest that configurations of facial muscles are inherently ambiguous, and they call for a different approach towards (...) the understanding of facial expressions of emotions. Prices of sticking with the modal view, and advantages of an expanded view, are succinctly reviewed. (shrink)

The current meta-analysis reviews 24 studies on self-reported emotional reactions to facial expressions in socially anxious versus nonanxious individuals. We hypothesized that socially anxious individuals would perceive all face types as less approachable, more negative, and more arousing. After correcting for biases, results showed that socially anxious individuals, compared to controls, reported lower approachability to all types of expressions and higher arousal in response to neutral expressions. Variances among effects usually could not be explained by the proposed moderators. This suggests (...) that current conceptualizations of social anxiety should take into account the willingness to approach social stimuli rather than global measures of emotion or arousal. (shrink)
