Neurophysiological studies have shown in animals that a sudden sound enhanced perceptual processing of subsequent visual stimuli. In the present study, we explored the possibility that such enhancement also exists in humans and can be explained through

Art and visual perception
free download

Psychological Forces: What a person perceives is not only an arrangement of objects, colors, shapes, movements and sizes, but, perhaps first of all, an interplay of directed tensions. The latter are inherent in any percept. Because they have magnitude and direction

Visual perception and world knowledge: Notes on a model of sensory-cognitive interaction

This exchange between subject and experimenter was invented by Miller to make a point about perceptual experience: Normal percep-tion is concerned with seeing real-world objects, not patches of color. The viewer finds it extremely difficult, even if pressed, to attend

Bayesian decision theory (BDT) is a mathematical framework that allows the experimenter to model ideal performance in a wide variety of visuomotor tasks. The experimenter can use BDT to compute benchmarks for ideal performance in such tasks and compare human

Visual imagery without visual perception

The question regarding visual imagery and visual perception remain an open issue. Many studies have tried to understand if the two processes share the same mechanisms or if they are independent, using different neural substrates. Most research has been directed towards

Disturbances of active visual perception with lesions of the frontal lobes
free download

Elaboration of complex visual information is an active process of selection of the most informative parts of the visual object, comparison of several details perceived, elaboration of hypotheses concerning the meaning of the whole and eduction of an appropriate meaning In this paper, we consider theories about processes of visual perception and perception – based knowledge representation (VPR) in order to explain difficulties encountered in figural processing in junior high school geometry tasks. In order to analyze such difficulties, we take
