Can the purpose of inspection influence the potency of visual salience in scene perception?
” Perception 35 ECVP Abstract Supplement Can the purpose of inspection influence the potency of visual salience in scene perception? T Foulsham, G Underwood Efficient perception of natural scenes depends on sampling the most relevant details by well-targeted shifts of attention. Salience map models predict that this sampling is controlled by a preattentive representation of the scene in terms of low-level feature discontinuities. These models have found some support, but an increasing emphasis on the task viewers are performing implies that salience must combine with cognitive demands to guide the eyes efficiently. We examined eye movements to objects in photographs while viewers performed a memory encoding task or one of two search tasks. The objects depicted in the scenes had known salience ranks according to the model proposed by Itti and Koch (2000 Vision Research 40 1489 – 1506). Participants fixated higher salience objects sooner and more often than lower salience objects, but on
