Perception

Front 1

Apparent movement

Back 1

The perception of movement produced by stimuli that are stationary but are presented first at one positions and then, at an appropriate time interval, presented at a different position.

Front 2

Binding problem

Back 2

The problem confronted by the brain of recombining the elements of a stimulus, given the fact that these elements are initially analyzed separately by different neural systems.

Front 3

Binocular disparity

Back 3

A depth cur based on the differences between the two eyes' views of the world. The difference becomes less pronounced the farther an object is from the observer.

Front 4

Correspondence problem

Back 4

As your view changes, the perceptual task of determining which aspects of the current view correspond to which aspects of the view seen a moment ago.

Front 5

Depth curs

Back 5

Sources of information that signal the distance from the observer to the distal stimulus.

Front 6

Feature net

Back 6

A model of pattern recognition involving a network of detectors and having creature detectors as the network's starting point.

Front 7

Geons (geometric ions)

Back 7

Simple geometric figures, such as cubes, cylinders, and pyramids, that can be combined to create all other shapes. An early (and crucial) step in some models of object recognition is determining which geons are present.

Front 8

Gestalt psychology

Back 8

A theoretical approach that emphasizes the role of organized wholes in perception and other psychological processes

Front 9

Good continuatikn

Back 9

A factor in visual grouping; we tend to perceive contours in a way that alters their direction as little as possible.

Front 10

Illusory conjunctiln

Back 10

A pattern of errors in which observers currently perceive the features present in a display, such as color and shape, but misperceive how they were combined.

Front 11

Induced motion

Back 11

Perceived movement of a stationary stimulus, usually caused by movement of a surrounding framework of nearby objects

Front 12

Interpolation

Back 12

A monocular cue to distance that relies on the fact that objects farther away are blocked from view by closer objects

Front 13

Linear perspective

Back 13

A cut for distance beard in the fact that parallel lines seem to converge as they get farther away from the viewer

Front 14

Magno cells

Back 14

Ganglion cells that, because of their sensitivity to brightness changes, are particularly suited to perceiving motion and depth. See also parvo cells

Front 15

Monocular depth curs

Back 15

Features of the visual stimulus that indicate distance even if the stimulus is viewed with only one eye.

Front 16

Motion detectors

Back 16

Cells in the visual cortex that are sensitive to an image moving in a particular direction across the retina

Front 17

Motion parallax

Back 17

A depth cue based on the fact that, as an observer moved, the retinal image of nearby objects move move rapidly than do the retinal images of the objects farther away.

Front 18

Parvo cells

Back 18

Ganglion cells that, because of their sensitivity to differences in hue, are particularly suited to perceiving color and form. See also magno cells.

Front 19

Perceptual constancy

Back 19

The accurate perception of certain attributes of a distal object, such as its shape, size, and brightness, despite changes in the proximal stimulus caused by variations in our viewing circumstances

Front 20

Pictorial curs

Back 20

Patterns that can be represented on a flat surface in order to create a sense of a three-dimensional object or scene

Front 21

Priming

Back 21

The process through which a detector or portion of the nervous system is prepared for an upcoming input, making it easier for the participant to recognize the input.

Front 22

Proximity

Back 22

In perception, the closeness of two figures. The closer together they are, the more we tend to group them together perceptually

Front 23

Reversible figure

Back 23

A visual pattern that easily allows more than one interpretation, in some cases changing the specification of figure and ground, in other cases changing the perceived organization in depth

Front 24

Similarity

Back 24

In perception, a principle by which we tend to group like figures, especially by color and orientation

Front 25

Subjective contours

Back 25

Perceived contours that do not exist physically. We tend to complete figures that have gaps in them by perceiving a contour as continuing along its original path

Front 26

Unconscious inference

Back 26

A process postulate by Hermann Von helmholtz to explain certain perceptual phenomena such as size consistency. For example, an object is perceived to be a certain distance and this is unconsciously taken into account in assessing it's retinal image size, with the result that size constancy is maintained.

Front 27

Visual seatch

Back 27

A task in which participants are asked to determine whether a specified target is present within a field of stimuli

Front 28

"What" system

Back 28

The visual pathway leading from the visual cortex to the temporal lobe; especially involved in identifying objects

Front 29

"Where" sustem

Back 29

The visual pathway leading from the visual cortex to the parietal lobe;especially involved in locating objects in space and cortina ting movements.
