Composite facial expressions were prepared by aligning the top half of one expression (e.g., anger) with the bottom half of another (e.g., happiness). Experiment 1 shows that participants are slower to identify the expression in either half of these composite images relative to a "noncomposite" control condition in which the 2 halves are misaligned. This(More)
We report three experiments investigating the recognition of emotion from facial expressions across the adult life span. Increasing age produced a progressive reduction in the recognition of fear and, to a lesser extent, anger. In contrast, older participants showed no reduction in recognition of disgust, rather there was some evidence of an improvement.(More)
Huntington's disease can particularly affect people's recognition of disgust from facial expressions, and functional neuroimaging research has demonstrated that facial expressions of disgust consistently engage different brain areas (insula and putamen) than other facial expressions. However, it is not known whether these particular brain areas process only(More)
Baron-Cohen [Mindblindness: an essay on autism and theory of mind. Cambridge, MA: MIT Press, 1997] has suggested that the interpretation of gaze plays an important role in a normal functioning theory of mind (ToM) system. Consistent with this suggestion, functional imaging research has shown that both ToM tasks and eye gaze processing engage a similar(More)
Lavenu et al. [Alzheimer Dis. Assoc. Disorder 5 (1999) 96] have shown that patients with frontotemporal dementia (FTD) show impaired recognition of facial expressions. It is not clear, however, whether these deficits arise from an impairment affecting face processing generally, emotion processing generally, or facial expression recognition alone. We address(More)
Comparative neuropsychology has identified a role for the ventral striatum (VS) in certain forms of aggression. To address whether the homologous region in humans also contributes to the emotion anger, we studied a case series of four human subjects with focal lesions affecting the VS. All four demonstrated a disproportionate impairment in recognizing human(More)
We present an investigation of facial expression recognition by three people (BC, LP, and NC) with Mobius syndrome, a congenital disorder producing facial paralysis. The participants were asked to identify the emotion displayed in 10 examples of facial expressions associated with each of 6 basic emotions from the Ekman and Friesen (1976) series. None of the(More)
For some people facial expressions of aggression are intimidating, for others they are perceived as provocative, evoking an aggressive response. Identifying the key neurobiological factors that underlie this variation is fundamental to our understanding of aggressive behaviour. The amygdala and the ventral anterior cingulate cortex (ACC) have been(More)
Studies in humans suggest that the amygdala plays a role in processing social information. A key component of social information processing is what developmental psychologists call "theory of mind": the ability to infer others' mental states. Recent studies have raised the possibility that the amygdala is involved in theory of mind, showing amygdala(More)
The anterior insula has been implicated in coding disgust from facial, pictorial and olfactory cues, and in the experience of this emotion. Personality research has shown considerable variation in individuals' trait propensity to experience disgust ('disgust sensitivity'). Our study explored the neural expression of this trait, and demonstrates that(More)
