The Centre for Research on Addiction Vulnerability in Early Life (CRAVE) Lab, directed by Dr. Matthew T. Keough, is a group of collaborators conducting research in the Department of Psychology at York University.  

Dr. Keough’s research program falls into two main areas. In his first area of work, Dr. Keough examines risk factors for addiction in early life (before the age of 30) using lab-based and longitudinal studies. In his second line of research, Dr. Keough aims to improve psychological treatments for concurrent disorders. 


Our team believes that treatment for concurrent disorders should be integrated, accessible, and engaging. We are currently running several large-scale randomized controlled trials looking at novel online treatments for concurrent disorders.


The addiction-related topics our team studies include:

Substance Use

Our substance use research involves investigating alcohol, cannabis, and tobacco use, among other substances.

Behavioural Addiction 

We investigate behavioural addictions like problems with gaming and gambling.

Neuropsychology and Addiction

Our research involves the applicability of neuropsychology to addiction – the study of brain and behaviour – via the use of technology like transcranial Direct Current Stimulation (tDCS).
