Outline of Final Research Achievements |
For animals to survive in their natural environments, rapid visual processing of visual inputs is of great relevance. Experiment 1 developed an RSVP procedure for pigeons, where pigeons were required to discriminate two bird pictures (the targets) each of which was briefly presented in a rapid sequence of other bird pictures (the distractors). By using the RSVP procedure, a series of experiments revealed that 1) pigeons require the minimum viewing time of 80 ms to identify the target, 2) if a distractor appears after the target processing has been completed, the target’s memory is not impaired by the distractor, 3) if the target terminates before its processing is completed, further processing is disrupted by the distractor, and 4) if only the target appears in the absence of distractors, visual processing of the target continues beyond its actual time in view.
