Craig Leth-Steensen is a cognitive psychologist with training in the application of quantitative/statistical techniques to the analysis of psychological data. One main focus of his research is the development of mathematical and computational models (including random walks and neural networks) that can provide theoretical accounts for human cognitive and psychophysical performance (especially with respect to reaction time and reaction time distributions). At present, Craig’s main experimental interests involve the study of comparative judgements of symbolically represented attributes (including numbers), speed –accuracy tradeoffs, and a wide variety of information processing phenomena (see papers listed below). Recently, Craig has also become interested in the cognitive development of very young children and has been performing experimental intervention work related to a very promising, novel early learning program called PlayWisely.
