The amygdala is known to play an important role in the response to facial expressions that convey fear. However, it remains unclear whether the amygdala's response to fear reflects its role in the interpretation of danger and threat, or whether it is to some extent activated by all facial expressions of emotion. Previous attempts to address this issue using(More)
The face-selective region of the right posterior superior temporal sulcus (pSTS) plays an important role in analysing facial expressions. However, it is less clear how facial expressions are represented in this region. In this study, we used the face composite effect to explore whether the pSTS contains a holistic or feature-based representation of facial(More)
Movements of the face play an important role in social communication. For example, changes in facial expression provide information on emotional state, whereas changes in viewpoint convey information about the direction of attention. Our aim was to determine whether there are distinct neural representations for different types of facial movement and whether(More)
Basic visual features such as contrast are processed in a highly nonlinear fashion, resulting in 'dipper' shaped functions in discrimination experiments. Previous work has applied a similar paradigm to investigate the representation of higher level properties such as facial identity (Dakin & Omigie, 2009, Vision Res, 49, 2285-2296). Here we ask whether(More)
