He has published over 150 scientific papers in neuropsychology and clinical psychology (You can view his publications as logged at ResearcherID). The topics of these papers are diverse but are unified by an emphasis on the development, evaluation, and application of quantitative methods.
He is one of the most highly cited neuropsychologists in the UK. In particular he has developed classical and Bayesian statistical methods for drawing inferences concerning the single case that are widely used in neuropsychology and related disciplines. Information on these methods can be found on this pdf.
A useful feature of many of Professor Crawford’s papers is the provision of accompanying computer programs. As a result, psychologists can quickly and reliably apply optimal statistical methods to their clinical or research data. The University of Aberdeen website contains all of Professor Crawford’s computer programs (many of these are primarily aimed at practitioners).
Singing the blues
When not trying to do difficult sums, he likes to walk the hills with his dogs, and sing and play the blues. He has also been known to sing 20 minute long unaccompanied Scottish ballads, so be warned.
