I am interested in processes related to learning, attention and emotion. I am particularly interested in how fear relevant stimuli, such as snakes and spiders, can so quickly capture our attention. I am also interested in whether a similar attentional bias exists for sufficiently positive stimuli.
My projects involve stimulus relevance and preferential attention; boundary conditions of evaluative learning; and learning and awareness.
Most of my work is conducted in the Emotion, Learning and Psychophysiology Laboratory: http://www2.psy.uq.edu.au/~landcp/
More information about my work in preferential processing and fear relevance is available on the project website: http://experiment.psy.uq.edu.au/fear/ [please note this project is no longer active].
