Cuing a location in space produces a short lived advantage in reaction time to targets at that location. Multiple diffusion models are presented for saccadic and manual reaction time for spatial cuing experiments with random CTOA and probe locations. Diffusion models can generate accurate distributions of reaction time data by modelling a response as a build-up of evidence towards a response threshold (Ratcliffe, 2008). An adapted diffusion model is presented which allows for spatiotemporal events to trigger changes in signal strength over time. One of the strengths of diffusion models is the ability to match model parameters with experimental manipulations to discover the potential underlying mechanisms of the decision process (Ludwig et al, 2009). Diffusion Models which allow temporal onsets have added potential to implement theories of attention which rely on sequential events and internal feedback mechanisms. Data from two experiments are presented with this model: pre and post cue effects thought to be caused feedback mechanisms and perceptual merging (Krueger et al, 2014); and new data on the transition timing of facilitation and Inhibition of Return.
