How do we use the past to predict the future in oculomotor search?

When we conduct visual search for an item of interest we can not only ask ‘what looks like my target’ but we can also ask ‘where do I expect the target to be?’ In a forthcoming paper in the journal¬†Vision Research¬†I asked: how do we use our past experience to construct predictions of where a […]

The prominence of behavioural biases in eye guidance

Abstract When attempting to understand where people look during scene perception, researchers typically focus on the relative contributions of low- and high-level cues. Computational models of the contribution of low-level features to fixation selection, with modifications to incorporate top-down sources of information have been abundant in recent research. However, we are still some way from […]

Using mixture modelling to distinguish between low- and high-level factors in natural image viewing

Abstract The allocation of overt visual attention while viewing photographs of natural scenes is commonly thought to involve both bottom-up feature cues, such as luminance contrast, and top-down factors such as behavioural relevance and scene under- standing. Profiting from the fact that light sources are highly visible but uninformative in visual scenes, we develop a […]

Systematic tendencies in scene viewing

Abstract While many current models of scene perception debate the relative roles of low- and high- level factors in eye guidance, systematic tendencies in how the eyes move may be infor- mative. We consider how each saccade and fixation is influenced by that which preceded or followed it, during free inspection of images of natural […]

Investigating a space-variant weighted salience account of visual selection

Abstract Weighted salience models are a popular framework for image-driven visual attentional processes. These models operate by: sampling the visual environment; calculating feature maps; combining them in a weighted sum and using this to determine where the eye will fixate next. We examine these stages in turn. We find that a biologically plausible non-uniform retinal […]
