Dr Wei Lin Toh

Senior Research Fellow


Dr Wei Lin Toh is a Senior Research Fellow within the Cognitive Neuropsychiatry Lab at Swinburne’s Centre of Mental Health.

Dr Toh’s current research work involves a comprehensive, multimodal assessment of hallucinatory experiences and associated delusions across a range of psychiatric diagnoses, with particular focus on documenting phenomenolgy as well as cognitive and perceptual correlates, as part of an NHMRC New Investigator grant.

Dr Toh graduated with a BA (Honours) in 2006, and a M.Psych/PhD (Clinical) in 2011 from the University of Melbourne. In her postgraduate dissertation, she examined perception and cognition in body dysmorphic disorder and obsessive-compulsive disorder, with the aid of eye-tracking technology.

PhD topics and outlines

Cognitive functioning in body dysmorphic disorder (BDD): People with BDD are preoccupied by physical ‘flaw(s)’ perceived as exceptionally ugly, relating to facial features or other body parts. The current study aims to examine general cognition, by assessing thirty-five patients using a neuropsychological test battery. Findings may improve our understanding of cognitive processes underlying BDD, and identify anomalies to serve as therapeutic targets.

Understanding the phenomenology of multimodal hallucinations in psychosis: Hallucinations occur when sensory events are perceived in the absence of corresponding external stimuli, and can involve any of our multiple senses. Despite its debilitating effects, little is known about these experiences across the modalities (except auditory). The current study thus aims to characterise the physical, cognitive and emotional features of multisensory hallucinations in psychosis.


Available to supervise honours students.

Honours topics and outlines

Understanding hallucinatory experiences in body image disorders and migraine: Hallucinations are unusual sensory experiences that can occur in any one of our multiple sense (e.g. hearing voices, seeing images, feeling sensations). This study aims to understand the characteristics of these experiences in psychiatric (i.e. body dysmorphic disorder and anorexia nervosa), neurological (i.e. migraine) and general populations, using a new multimodal hallucinations measure.
