Color singleton pop-out does not always poop out: an alternative to visual search.
Folk psychology suggests that when an observer views a scene, a unique item will stand out and draw attention to itself. This belief stands in contrast to numerous studies in visual search that have found that a unique target item (e.g., a unique color) is not identified more quickly than a nonunique target. We hypothesized that this finding is the result of task demands of visual search, and t...
متن کاملThe time-course of pop-out search
Olds, Cowan and Jolicoeur [2000. Tracking visual search over space and time. Psychonomic Bulletin & Review (in press)] interrupted pop-out search by adding distractors to a display after a delay. They analyzed the response time distributions from conditions with different delays for interruption and showed that when pop-out search fails, its partially completed computations can be used to assis...
متن کاملMeasuring Preattentive Processes: When is Pop-out Not Enough?
Three behavioural tasks (standard visual search, multiple target search, and numberdiscrimination)weretestedwithavariety of stimuli relevanttotwo-stage theories of vision. One purpose was to compare the two versions of the search task; a second was to explore the relations between processes of search and enumeration.

متن کاملDo People “Pop Out”?
The human body is a highly familiar and socially very important object. Does this mean that the human body has a special status with respect to visual attention? In the current paper we tested whether people in natural scenes attract attention and "pop out" or, alternatively, are at least searched for more efficiently than targets of another category (machines). Observers in our study searched ...
متن کاملDepression does not affect time perception and time-to-contact estimation
Depressed patients frequently report a subjective slowing of the passage of time. However, experimental demonstrations of altered time perception in depressed patients are not conclusive. We added a timed action task (time-to-contact estimation, TTC) and compared this indirect time perception task to the more direct classical methods of verbal time estimation, time production, and time reproduc...
