Change Detection Research Interests
I have been using the flicker paradigm for inducing change blindness as a dumb tool in place of the Stroop paradigm to explore information processing biases towards substance-related stimuli in 'social' users (of cannabis and alcohol). The flicker ICB paradigm reveals that in higher social users the change detection latency for changes to substance-related stimuli is lower than to neutral stimuli but this effect does not show in lower social users. The paradigm is easier to implement and manage than the Stroop and this is what attracted me, at first at least. In some of the experiments (reported in Psychopharmacology) we have provided ('in competition') a substance-related and a neutral change in the same stimulus. We find that participants detecting the substance-related change have a higher social use than those spotting the neutral change. More recently I have become interested in the processes underpinning the change detection and particularly those in which the layout of the scene in which the change is embedded impacts on detection latency.
