Experience-Dependent Perceptual Grouping and Object-Based Attention
Attention can be allocated to objects as well as locations, even if the objects are partially occluded. A fundamental question concerns the nature of the ‘objects’ of this attention. Recent studies show that objects can be defined based on Gestalt grouping principles, or based on familiarity. The effects of both grouping and familiarity can be understood in terms of amore general hypothesis: th...
متن کاملObject-based perceptual grouping affects negative priming.
In 5 experiments the authors examine the role of object-based grouping on negative priming. The experiments used a letter-matching task with multiple letters presented in temporally separated prime and probe displays. On mismatch trials, distractor letters in primes were repeated as targets in probes, or distractor and target letters were completely different. Negative priming was shown by slow...
متن کاملContrast-sensitive perceptual grouping and object-based attention in the laminar circuits of primary visual cortex
Recent neurophysiological studies have shown that primary visual cortex, or V1, does more than passively process image features using the feedforward filters suggested by Hubel and Wiesel. It also uses horizontal interactions to group features preattentively into object representations, and feedback interactions to selectively attend to these groupings. All neocortical areas, including V1, are ...
متن کاملAuditory perceptual grouping and attention in dyslexia.
Despite dyslexia affecting a large number of people, the mechanisms underlying the disorder remain undetermined. There are numerous theories about the origins of dyslexia. Many of these relate dyslexia to low-level, sensory temporal processing deficits. Another group of theories attributes dyslexia to language-specific impairments. Here, we show that dyslexics perform worse than controls on an ...
متن کاملPerceptual load modulates object-based attention.
Two experimental series are reported using both reaction time (RT) and a data-limited perceptual report to examine the effects of perceptual load on object-based attention. Perceptual load was manipulated across 3 levels by increasing the complexity of perceptual judgments. Data from the RT-based experiments showed object-based effects when the target was near the cued location. Results from th...
