Visual Search for Change: A Probe into the Nature of Attentional Processing

The experiments presented here provide considerable evidence for the proposal that focused attention is required to see change. Experiment 1 showed that visual search for change is a self-terminating process that requires time linear in 370 RENSINK 9 The distributions are normalized by a count that includes errors (such as responses made before epoch 1) and long RTs (responses made after epoch 5). Consequently, the values for the epochs described can add up to less than 100%.
