Professor Chris Chandler is Head of Psychology at London Met. Chris is a psychobiologist and came to London Met from the Institute of Psychiatry in 1996. He has previously been course leader for undergraduate programmes and postgraduate programmes in psychology and mental health.
Chris's research interests are primarily in the neuropsychology of addiction, but also in Attention Deficit Hyperactivity Disorder (ADHD). He has supervised PhD students in these areas.
Chris specialises in psychobiology, addiction and Attention Deficit Hyperactivity Disorder (ADHD). His research interests are addiction psychology and drug use and ADHD.
Chris has supervised the following students on their PhD:
- Dr Lynn Taurah – A cohort study of the acute and long-lasting psychological effects of 3, 4-Methylenedioxymethamphetamine (MDMA, ‘Ecstasy’) during the period 2002-2007
- Dr Anita Singh-Andrews – Information processing of auditory and visual nicotine cues in smokers, ex-smokers and non-smokers.
- Dr Sharon Cox – The effect of alcoholism on visuospatial perspective taking
- Dr Jo Lusher – Vulnerability to substance dependence
Chris has also worked on various projects:
The effects of the ovulatory cycle on the neuropsychology of drug-taking behaviour
It has been noted that the week preceding menstruation is a period (forgive the pun) in which women may be more vulnerable to drug consumption and relapse. This project seeks to investigate the potential relationship between addiction behaviours (craving and neuropsychological factors) and the hormonal/behavioural changes during the menstrual cycle.
The neuropsychology of impulsivity and attentional bias in drug users
This project is aimed to determine the relationship between impulsivity as measured by tasks of behavioural inhibition (e.g. Go-Nogo task) and the link of the well-known phenomenon of attentional bias. By modifying traditional behavioural inhibition tasks with integral attentional bias we aim to determine the impact of attention on impulsivity in drug users. We are continuing to evaluate behavioural inhibition against working memory as an endophenotype for addiction.
Pro-social Behaviours and Theory of Mind in Alcohol users
Whilst it is understood that addiction has detrimental effects on pro-social behaviour, the specific effect that addiction has on a range of socially important behaviours is relatively unknown. Functional socialisation is not only a consequence of - and necessary for - one’s own affect regulatory state, but also for maintaining cohesion within society. During addiction, one develops an acute awareness of drug-related objects, perhaps at the expense of pro-social behaviour. This project seeks to understand the nature of pro-social behaviour in alcohol users and how they process social cues (eg theory of mind). This was a collaborative project with Dr Sharon Cox (University of Kent) and Dr Kevin Riggs (University of Hull).
Dopamine Receptors and Behaviour
This research focused on identifying a behavioural role for the Dopamine D1 receptor. The work here has identified a facility role for the receptor, together with the dopamine D2 receptor on motor behaviour. The significance of this work relates directly to diseases such as schizophrenia, Parkinson's disease, ADHD and addiction. Additionally, this work discovered a potential link between the level of receptor activity and motor seizures.
