Perceptual Grouping Enhances Visual Plasticity
Visual perceptual learning, a manifestation of neural plasticity, refers to improvements in performance on a visual task achieved by training. Attention is known to play an important role in perceptual learning, given that the observer's discriminative ability improves only for those stimulus feature that are attended. However, the distribution of attention can be severely constrained by percep...
متن کاملInspection time and visual–perceptual processing
Inspection time (IT) is the most popular simple psychometric measure that is used to account for a large part of the variance in human mental ability, with the estimated corrected correlation between IT and IQ being -0.50. In this study, we investigate the relationship between IT and the performance and oculomotor variables measured during three simple visual tasks. Participants' ITs were first...
متن کاملVisual motion processing and perceptual decision making
The model works with n dimensions, continuous choices and any integrate-to-threshold decision model. The model has a 300ms constant motor response time added. The maximum trial length for both the experiment and model is 800ms. The model performs similarly well using 4and 8-choice decisions. The monkey response at 0% coherence may indicate ‘guess’ formulation involving non-sensory mechanisms (S...
متن کاملPerceptual Similarity in Visual Metaphor Processing
In visual metaphor processing, one object, the target, is compared to and understood in terms of another object, the source. Several studies suggest that perceptual similarity between two objects enhances a conceptual link between the two. However, little is known about how perceptual features contribute to the establishment of this link. In the present experiment we investigated the processing...
متن کاملPerceptual Rivalry: Reflexes Reveal the Gradual Nature of Visual Awareness
Rivalry is a common tool to probe visual awareness: a constant physical stimulus evokes multiple, distinct perceptual interpretations ("percepts") that alternate over time. Percepts are typically described as mutually exclusive, suggesting that a discrete (all-or-none) process underlies changes in visual awareness. Here we follow two strategies to address whether rivalry is an all-or-none proce...
