Perceptual hypothesis

Palmer December Figure 1 - Box When an observer views a two-dimensional picture on paper, he often interprets it as a three-dimensional figure.

Perceptual hypothesis

Subjective constancy Perceptual constancy is the ability of perceptual systems to recognize the same object from widely varying sensory inputs. A coin looked at face-on makes a circular image on the retina, but when held at angle it makes an elliptical image.

Without this correction process, an animal approaching from the distance would appear to gain in size. The brain compensates for this, so the speed of contact does not affect the perceived roughness. Principles of grouping Law of Closure.

The human brain tends to perceive complete shapes even if those forms are incomplete. The principles of grouping or Gestalt laws of grouping are a set of principles in psychologyfirst proposed by Gestalt psychologists to explain how humans naturally perceive objects as organized patterns and objects.

Gestalt psychologists argued that these principles exist because the mind has an innate disposition to perceive patterns in the stimulus based on certain rules.

These principles are organized into six categories: The principle of proximity states that, all else being equal, perception tends to group stimuli that are close together as part of the same object, and stimuli that are far apart as two separate objects.

The principle of similarity states that, all else being equal, perception lends itself to seeing stimuli that physically resemble each other as part of the same object, and stimuli that are different as part of a different object.

This allows for people to distinguish between adjacent and overlapping objects based on their visual texture and resemblance. The principle of good continuation makes sense of stimuli that overlap: The principle of common fate groups stimuli together on the basis of their movement.

When visual elements are seen moving in the same direction at the same rate, perception associates the movement as part of the same stimulus. This allows people to make out moving objects even when other details, such as color or outline, are obscured.

The principle of good form refers to the tendency to group together forms of similar shape, pattern, coloretc.

Contrast effect A common finding across many different kinds of perception is that the perceived qualities of an object can be affected by the qualities of context. If one object is extreme on some dimension, then neighboring objects are perceived as further away from that extreme.

Perceptual learning With experience, organisms can learn to make finer perceptual distinctions, and learn new kinds of categorization. Wine-tasting, the reading of X-ray images and music appreciation are applications of this process in the human sphere.

Specifically, these practices enable perception skills to switch from the external exteroceptive field towards a higher ability to focus on internal signals proprioception. Also, when asked to provide verticality judgments, highly self-transcendent yoga practitioners were significantly less influenced by a misleading visual context.

Increasing self-transcendence may enable yoga practitioners to optimize verticality judgment tasks by relying more on internal vestibular and proprioceptive signals coming from their own body, rather than on exteroceptive, visual cues.

Perceptual hypothesis

Set psychology A perceptual set, also called perceptual expectancy or just set is a predisposition to perceive things in a certain way.

Subjects who were told to expect words about animals read it as "seal", but others who were expecting boat-related words read it as "sail". They were told that either a number or a letter would flash on the screen to say whether they were going to taste an orange juice drink or an unpleasant-tasting health drink.

In fact, an ambiguous figure was flashed on screen, which could either be read as the letter B or the number Primary tendencies in perceptual organization Gestalt principles. Gestalt theory was meant to have general applicability; its main tenets, however, were induced almost exclusively from observations on visual perception.

Whatever their ultimate theoretical significance, these observations have been raised to the level of general principles. Start studying Perceptual hypothesis. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
