Abstract

We have a special talk scheduled for March the 3rd (between 2 and 3pm) with Nonie Finlayson, a visiting Postdoc from UCL , giving a talk about the effect of depth information on visual search. Please spread it around to anyone who might be interested!

The effects of depth information on visual search Craik-Marshall room, Friday March 3rd, 2-3pm Nonie J. Finlayson

We live in a 3D world, and yet the majority of vision research is restricted to 2D phenomena. Visual attention can be shifted through 3D space, and as long as 30 years ago it was suggested that depth information can be used to organize visual space to improve search performance. However, more recent research has failed to replicate this advantage for depth information under different circumstances, and further suggested that we are unable to hold our attention to just one depth while ignoring others. In this talk I describe evidence supporting the benefits of visual search in depth, and outline the required parameters to take advantage of depth information in visual search. I will then present results that examine visual search in depth more generally, describing how each of four parameters of 3D visual space can influence visual search performance.
