The Dot-Probe task has been widely used in research on affective disorder and addiction in human subjects. Briefly, the subject has to choose one of two buttons to indicate in which of two locations a dot appears, where the two locations are jointly preceded by presentation of drug/spider etc image on one side, and a neutral image on the other. The latency to respond to the side contralateral to the clinically-relevant image is interpreted as a measure of attentional bias.
I'm wondering if anyone has developed a task like this for rodents, to see whether presentation of a drug-conditioned CS+ in a spatial part of the animal's environment delays/distracts an operant response unrelated to the drug in another spatial location.
