Stimulus repetition effects on texture-based visual search by pigeons.
Four experiments investigated the effects of within-session stimulus repetition on texture discrimination. Six pigeons (Columba livia) searched for a contrasting target region (color or shape) randomly embedded within a larger distractor region for food reinforcement. Experiment 1 found that repeating features of the distractors, but not those of the target, across trials increased the accuracy...
متن کاملPriming in visual search: Separating the effects of target repetition, distractor repetition and role-reversal
Recent studies have identified between-trial priming effects in visual search tasks, but often with constraints on the possible similarities or changes across successive trials, and usually with the main emphasis on effects of target repetition. Here we sought to obtain a more thorough characterization of between-trial priming effects in speeded visual search, where observers determined target ...
متن کاملRepetition priming in visual search: episodic retrieval, not feature priming.
Previous research has shown that when the targets of successive visual searches have features in common, response times are shorter. However, the nature of the representation underlying this priming and how priming is affected by the task remain uncertain. In four experiments, subjects searched for an odd-sized target and reported its orientation. The color of the items was irrelevant to the ta...
متن کاملSelective scanpath repetition during memory-guided visual search
Visual search efficiency improves with repetition of a search display, yet the mechanisms behind these processing gains remain unclear. According to Scanpath Theory, memory retrieval is mediated by repetition of the pattern of eye movements or "scanpath" elicited during stimulus encoding. Using this framework, we tested the prediction that scanpath recapitulation reflects relational memory guid...
متن کاملSpatially specific FMRI repetition effects in human visual cortex.
The functional MRI (fMRI) response to a pair of identical, successively presented stimuli can result in a smaller signal than the presentation of two nonidentical stimuli. This "repetition effect" has become a frequently used tool to make inferences about neural selectivity in specific cortical areas. However, little is known about the mechanism(s) underlying the effect. In particular, despite ...
