Carpenter focussed on mechanisms of decision in his work. Measurement of saccadic latency, the time taken to choose a visual target and initiate an eye movement, is a reliable method for obtaining reaction time data. This work has inspired a model referred to as LATER (Linear Approach to Threshold with Ergodic Rate) to explain the decision mechanism. Technological advances enabled oculomotor measurements to be made both quickly and non-invasively, using micro-devices which have many clinical applications.Selected publications
