One-step feature-based learning in the deployment of transient attention

A Kristjansson, K Nakayama

Previously we have shown that when transient visual attention is summoned by a sudden luminance onset, these deployments can be focused to a part of the suddenly appearing object that has proved behaviourally relevant on previous appearances [Kristjansson et al, 1999 Investigative Ophthalmology & Visual Science 40(4) S80]. This learning of a cue - target relationship was not under voluntary control and developed over the course of a few trials. Here we further investigate this form of learning during deployments of visual attention.

In experiment 1 we show that when there is consistent relationship between the colour of a part of the cue and a target, learning develops rapidly. Such learning was also observed for a similar relationship based on the shape of the cue, whereas a higher-order relationship between the cue and the target, where the colour of the cue predicted where the target would appear, did not result in the same form of learning. Thus we hypothesise that transient attention is capable of one-step inferences, based on particular features. These results are further evidence for the surprising adaptability of transient attention shifts to abrupt luminance onsets, which have often been thought to be stereotypical, stimulus driven, bottom - up reflexes.
