© John Charlton 2013 - 2020
I established Focus Statistics in 2013. Prior to this I conducted research and taught research design and statistics to undergraduate and postgraduate psychology students for over two decades at the University of Bolton where I became a Reader in Psychology. I hold BSc (Hons) and PhD degrees, have numerous publications (see the list below) and received a 2012 award from Elsevier for a 2007 paper on computer game addictions which was one of the top ten cited articles in Computers in Human Behavior during the five year period between 2007 and 2011. Citation details of my publications can be found on ResearchGate and Google Scholar.
John Charlton BSc (Hons), PhD
While at Bolton my main research interests centred upon individual differences in computer-related attitudes and behaviours. My other areas of interest included decision making, economic psychology and educational psychology. In addition to my research and lecturing activities, I was Psychology Postgraduate Research Admissions Tutor, a member of the Board of Studies for Research Degrees (the university’s research degree awarding body), Chair of the University Research Ethics Committee and the Department of Psychology’s Research Ethics Officer. I was also a reviewer for numerous journals and grant awarding bodies, and both supervised and examined PhD and MPhil research degree candidates.
