Programming

My skills and experience fall into two categories:­

Human Experimental Psychology

I have programmed a number of elementary cognitive tasks and other standard techniques in human experimental psychology, mostly using the Acorn RISC-OS environment because of the ease with which this operating system allows interfacing, precise timing, and sophisticated display capabilities through multiple banks of screen memory. Some of these were for the Ministry of Defence (with Jon May).

Psychometric Techniques

Standard statistical packages are notoriously slow at keeping up with the research literature, and so it is necessary to program many of them oneself. My programs include those for factor analysis (including exotica such as Velicer's MAP test, item-parceling, and polychoric correlations), routines for calculating many different measures of association, a simulation of Larsen & Diener's model of affect intensity, routines for generating plasmodes for the evaluation of factor analyses, and my main research interest is currently into a novel method of factor analysis which generates and tests all possible simple-structure models.

I would be pleased to consider writing (and supporting) programs in either of these areas.
