Ap Psych Chap 4 Review

Ventral Stream

Ventral Stream

________= processes the details of what objects are out there, the perception of form and color.Prosopagnosia= an inability to recognize familiar faces.Pathway of visual signals, .Optic nerve- Optic chiasm- thalamus- occipital lobe If you mix red, green, and blue paint, .you get black.

Brightness

________= the amount of light being receivedBlind Spot in the eye is where= optic disk Light adaptation= the process whereby the eyes become less sensitive to light in high illumination.Retina= the neural tissue lining the inside back surface of the eye: it absorbs light, processes images, and sends visual information to the brain.Fovea= a tiny spot in the center of the retina that contains only cones: visual acuity is greatest at this spot.Cones= specialized visual receptors that play a key role in daylight vision and color vision.

Receptive Field

________= the retinal area that, when stimulated, affects the firing of that cell.45 B What would need to be cut in order to increase the perception of pain= Glial cells /endorphins Glial cells= provides various types of support for neurons.

Trichromatic Theory

________= Thomas Young, the human eye has three types of receptors with differing sensitivities to different light wavelengths.

Performance

________ depends on the criterion or standard, you set for how sure you must feel before you react.Signal Detection Theory= attempts to account for the influence of decision- making processes on stimulus detection.Subliminal= below threshold We perceive changing stimuli better than constant ones.

Cognitive Interpretation

________= according to Schachter, the experience of emotion depends on ________ of that arousal.Perceptual Set= a readiness to perceive stimulus in a particular way.Bottom Up Processing= a progression from individual elements to a whole.Top Down Processing= A progression from the whole object to the elements.Figure Ground= figure is the thing being looked at, and the ground is the background against which it stands.

Rods

________= specialized visual receptors that play a key role in night vision and [peripheral vision.

ledPerceptual Hypothesis

Closure= People often group elements to create a sense of closure, or completeness.Continuity= reflects peoples tendency to follow in whatever direction they have been ________= an inference about what form could be responsible for a pattern of sensory stimulation.Distal Stimuli= external source of stimulation as it exists in the world Depth perception= The interpretation of visual cues that indicate how near or far away objects are.Linear Perspective= a depth cue reflecting the fact that lines converge in the distance.Interposition= if an object comes between you and another object, it must be closer to you.Perceptual Constancy= a tendency to experience a stable perception in the face of continually changing sensory input.Auditory Canal= where soundwaves are collected and funneled toward the eardrum Function of the middle ear is to amplify sound.
