There is good reason to believe that gaze direction and facial displays of emotion share an information value as signals of approach or avoidance. The combination of these cues in the analysis of social communication, however, has been a virtually neglected area of inquiry. Two studies were conducted to test the prediction that direct gaze would facilitate(More)
The amygdala is thought to be part of a neural system responsive to potential threat (1). Consistent with this is the amygdala’s well-documented sensitivity to fear faces. What is puzzling, however, is the paucity of evidence for a similar involvement of the amygdala in the processing of anger displays. To address this apparent anomaly, researchers have(More)
Knowledge about environmental objects derives from representations of multiple object features both within and across sensory modalities. While our understanding of the neural basis for visual object representation in the human and nonhuman primate brain is well advanced, a similar understanding of auditory objects is in its infancy. We used a name(More)
The ability to infer others' thoughts, intentions, and feelings is regarded as uniquely human. Over the last few decades, this remarkable ability has captivated the attention of philosophers, primatologists, clinical and developmental psychologists, anthropologists, social psychologists, and cognitive neuroscientists. Most would agree that the capacity to(More)
Research has largely neglected the effects of gaze direction cues on the perception of facial expressions of emotion. It was hypothesized that when gaze direction matches the underlying behavioral intent (approach-avoidance) communicated by an emotional expression, the perception of that emotion would be enhanced (i.e., shared signal hypothesis).(More)
Humor is a uniquely human quality whose neural substrates remain enigmatic. The present report combined dynamic, real-life content and event-related functional magnetic resonance imaging (fMRI) to dissociate humor detection ("getting the joke") from humor appreciation (the affective experience of mirth). During scanning, subjects viewed full-length episodes(More)
We investigated how shape features in natural images influence emotions aroused in human beings. Shapes and their characteristics such as roundness, angularity, simplicity, and complexity have been postulated to affect the emotional responses of human beings in the field of visual arts and psychology. However, no prior research has modeled the(More)
The origins of the appearances of anger and fear facial expressions are not well understood. The authors tested the hypothesis that such origins might lie in the expressions' resemblance to, respectively, mature and babyish faces in three studies. In Study 1, faces expressing anger and fear were judged to physically resemble mature and babyish faces. Study(More)
Face gender, like many other things, is perceived categorically: Subjective perceptions are distorted toward the categories, male or female, and the objective gradiency inherent across faces is partially lost. The neural basis of such categorical face perception remains virtually unknown. Participants passively viewed faces whose sexually dimorphic content(More)
Previous work has shown that individuals agree across cultures on the traits that they infer from faces. Previous work has also shown that inferences from faces can be predictive of important outcomes within cultures. The current research merges these two lines of work. In a series of cross-cultural studies, the authors asked American and Japanese(More)
