Research Summary

Research Areas: Joel Pearson studies Cognitive Neuroscience, specifically the mechanisms and application of mental imagery, hallucinations, decision-making, the science of intution, memory, metacognition, visual perception, learning, attention and awareness by using behavioural, human brain imaging and brain stimulation techniques.

Post-traumatic stress disorder and anxiety: assessment, mechanisms, and treatment.

Joel is the founder and director of the UNSW Science of Innovation Lab or SIL. A hands on empirical lab that develops new methods to scientifically study all related aspects of innovation using Psychology and Neuroscience. Many of the qualities or skills thought to be important for innovation: intuition, creativity, resilience, thinking outside the box etc. rely on subjective self-report questionnaires or are considered beyond the scope of science SIL is changing all that!
