Ostracism and Aggression. Ostracism has been implicated in school shootings (e.g., Columbine) and other violent or anti-social episodes (e.g., Port Arthur shootings). Some argue that ostracism drives individuals toward joining violent extremist groups. Research, however, is mixed: sometimes targets of ostracism correct their behaviors to be more socially acceptable; whereas other times they react with aggression. This research program will investigate the conditions under which ostracism either ....Ostracism and Aggression. Ostracism has been implicated in school shootings (e.g., Columbine) and other violent or anti-social episodes (e.g., Port Arthur shootings). Some argue that ostracism drives individuals toward joining violent extremist groups. Research, however, is mixed: sometimes targets of ostracism correct their behaviors to be more socially acceptable; whereas other times they react with aggression. This research program will investigate the conditions under which ostracism either leads to paths of either pro-social or aggressive reactions. A new virtual reality paradigm will be developed to provide stronger manipulations of ostracism and to assist in discovering the crucial conditions responsible for these paths.Read moreRead less
Neural mechanisms for human form perception. This project aims to determine if there is a single cortical mechanism underlying the human ability to discriminate and recognise objects. It has been speculated that different classes of objects, or forms require different processes. Demonstrating a single process would be a significant advance towards understanding the neural mechanisms giving rise to our ability to segment visual fields into meaningful objects and background. This research provides ....Neural mechanisms for human form perception. This project aims to determine if there is a single cortical mechanism underlying the human ability to discriminate and recognise objects. It has been speculated that different classes of objects, or forms require different processes. Demonstrating a single process would be a significant advance towards understanding the neural mechanisms giving rise to our ability to segment visual fields into meaningful objects and background. This research provides a means for testing models of the neural interactions thought to be generating human form perception and will help us discover how the visual cortex converts raw sensory input into object and form perception.Read moreRead less
Motherese by ear and eye: infant perception of visual prosody. The project breaks new ground in auditory-visual speech processing by using naturally expressive continuous speech to probe how infants perceive visual prosody. A strength of the project lies in its use of breakthrough animation technologies to create a state-of-the-art virtual Talking Mother to enable control of visual speech cues.
