Cognitive and Clinical Neuropsychology, specifically of visual and somatosensory attention, and belief formation. I investigate these aspects of cognition by studying both individuals following right-hemisphere stroke, especially those suffering from unilateral neglect, sensory loss, or anosognosia for motor impairments, and by studying neurologically healthy individuals.
The intersection of social and personality psychology, focusing on phenomena such as social attitudes (ethnocentrism, prejudice, and authoritarianism) and personality factors shown to be related to social attitudes (narcissism and the Big Five personality traits); psychometrics; cross-cultural research; and scale development.
Relationship between stress, psychosocial factors (e.g. coping, social support), mental health (e.g. anxiety, depression) and chronic illness (e.g. fatigue, relapse) in chronic illness patients; impact of chronic conditions on psychological health and quality of life in people with multiple sclerosis, cancer, fatiguing illness, overweight/obesity and autism spectrum disorder; role of behaviour (e.g. physical activity, sleep disturbance) in contributing to overweight/obesity, fatigue and psychological illness; and stress, burnout and empathy in health professionals.
Neuropsychology, psychopathology, psychotic disorders (Schizophrenia), affective disorders (major depression), traumatic brain injury, cognitive neuroscience, assessment, measurement.
Social relationships and their effect on physical and mental health; the interface between social and clinical psychology; social determinants of health; social influence; social identity; depression; eating; health risk behaviours; vulnerable populations
Emotion; facial expressions; computer-generated faces and avatars; human-avatar bonding; empathy; psychopathic traits; personality; EEG and fast periodic visual stimulation; interfacing clinical and cognitive psychology.
Visual perception, with a major focus on how various pathways in the visual system function and interact with each other. Certain clinical disorders may result from, or in, neurological damage to the visual system. Hence investigating visual functioning in these disorders provides an effective way to investigate the neural pathology underlying them. To date my students have investigated the neural pathology underlying dyslexia and the visual impairments associated with long-term ecstasy use.
Visual cognition, including attention, awareness, and object perception. I am particularly interested in the mechanisms that determine which stimuli from the environment are selected for preferential processing and access to conscious awareness, and how such processes are altered as a function of a person’s goals or mental state.
Psycholinguistics including sentence processing in children and adults; the acquisition of complex sentences; the acquisition of verb argument structure and verbal morphology; how children deal with lexical and syntactic ambiguity in acquisition; and the linguistic skills of children with imaginary companions.
Memory and high-level perception, specifically: face recognition; implicit memory; short-term implicit memory; false memories; word recognition; object recognition.
Memory and cognition, cognitive biases, distortions in belief and memory, misinformation, assessments of truth. I examine the cognitive mechanisms that contribute to memory and belief and the ways these processes can go awry. I am especially interested in how people can succumb to truthiness—using feelings and pseudoevidence to decide what is real, instead of drawing on facts. This research area has important applications in Law, Science Communication, and Education.
Language and psychopathology; clinical, theoretical and intervention research into obsessive-compulsive disorder and posttraumatic stress disorder.
Parenting and the parent-child relationship; child and youth antisocial behaviour and callous-unemotional traits; family-based treatment and prevention; child maltreatment.
Social psychology: social identity and self-categorisation; distributive and procedural fairness in interpersonal and intergroup settings; social influence; leadership; group-based trust.
Prejudice, stereotyping, intergroup conflict and cooperation; the interface between social and organisational psychology (e.g., diversity management, leadership and organisational change).
