Change Detection Research Interests
I first got interested in change detection in 1987 when I found people were rather lousy at detecting changes in arrays of familiar objects when the offset was even 100 msec long (Pashler, 1988); I was very surprised that I could only "hang on to" 4-5 objects (i.e., ~ whole report span). Phillips had. made similar observations with matrix-patterns but I had thought that using familiar objects would surely reveal lots more information. To my aggravation, reviewers were split on whether the result was astonishing or obvious, so to convince the editor it wasn't so obvious I polled a bunch of people at Psychonomics without telling them the result; to my relief, few of them predicted it (Howard Egeth was one who did). Currently I am happy to be collaborating with Mark Becker on several sets of studies on which he will be lead author; these look at the relation between change detection and other measures of semantic processing of multiple items in a scene; the role of masking and iconic memory in change detection; change detection in moving scenes; and still other topics.
Other Research Interests
Attention, dual-task performance, short-term memory, perceptual learning, skill learning, higher-level visual perception.
