Fréttatilkynning verkefnisstjóra


As we interact with the environment, our gaze and attention are pulled towards items that we have interacted with before and are behaviourally important to us. We have investigated such attentional function with visual foraging tasks where observers attempt to collect as many items as they can. 

The findings from these tasks have indicated that the selection processes of visual attention are far more intricate and multifaceted than theories of visual attention that have been dominant over the last close-to 50 years would predict. For example the results suggest that theories with simple fixed capacity limits may be too restrictive. A participant’s strategy may reflect a more complex interaction between capacity and task demands. Secondly, typical response time patterns from visual search tasks are only seen for the last target within a foraging trial, and these selections are also much slower than the majority of other selections. Thirdly targets that are distinguishable from distractors by a single color should pop-out in a feature map, but they clearly do not always do that. Fourth, selection times were comparable for feature and conjunction foraging, while the run pattern differed strongly between those conditions.

Secondly, our studies of visual foraging and visual search have shown that we can use such tasks, and the priming effects that occur within them to probe the nature of observers representations of ensembles of visual stimuli. This method enables us to reveal far more intricate representations of stimulus ensembles than have previously been found in the literature.
