Chapter 5 - Sensation and Perception

________- Objects in the peripheral retina disappear under conditions of steady, unmoving stimulation but are revitalized by movement in the periphery.

________-"System for sensing the position and movement of individuals body parts "(pg.

________-"Perceiving objects as unchanging… even as illumination and retinal images change "(pg.

________- Part of your body still knows whats going on.

________-"the process of converting one form of energy into another that our brain can use "(pg.

Sensation (Bottom- Up Processing)-"the process by which our sensory receptors and ________ receive and represent stimulus energies from our environment "(pg.

________- Difference thresholds increase in proportion to the size of the stimulus.

________- ability to become highly involved in sensory or imaginative sequences.

________-"the minimum stimulus energy needed to detect a particular stimulus "(pg.

________- skepticism makes it less likely to work.

________- objects not being in the same place when off- center in front of you and looked at by one eye, helping you more accurately perceive distance.

________- the study of the relationship between physical stimulation and psychological experience.

________ are concentrated around the fovea, while the color- blind rods dominate the periphery of the retina.

Our ability to maintain balance depends on ________.

________- Reflex movement evoked by vestibular stimulation.

________ uses parallel processing of sensory information.

________- split in consciousness that allows some thoughts and behaviors to occur simultaneously with others.

________- use one eye to perceive depth of objects far from us.

________- persons ability to become deeply hypnotized; suggestibility.

________- Rely on vestibular cues.

________- Rely on visual cues.

"the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment" (pg

"the process by which our brain organizes and interprets sensory information, transforming it into meaningful objects and events" (pg

"the process of converting one form of energy into another that our brain can use" (pg

the study of the relationship between physical stimulation and psychological experience

"the minimum stimulus energy needed to detect a particular stimulus" (pg

Individual absolute thresholds vary with our psychological state (expectations, motivations, and alertness)

The minimum difference in stimulation that a person can detect 50% of the time

Difference thresholds increase in proportion to the size of the stimulus

German for "form"; "whole"

Visual cliff

objects not being in the same place when off-center in front of you and looked at by one eye, helping you more accurately perceive distance

binocular cues and monocular cues

use both eyes to perceive depth of objects close to us

use one eye to perceive depth of objects far from us

Objects in the peripheral retina disappear under conditions of steady, unmoving stimulation but are revitalized by movement in the periphery

"Perceiving objects as unchanging… even as illumination and retinal images change" (pg

Noticing where on your body you experience touch

"System for sensing the position and movement of individuals body parts" (pg

"Sense of body movement and position, including the sense of balance" (pg

Reflex movement evoked by vestibular stimulation

Rely on visual cues

Rely on vestibular cues

Hypnosis can be explained through other psychological experiences (Putting on an act as a good subject, even subconsciously)

Separating into parts of yourself (Believing when given the suggestion of something)

split in consciousness that allows some thoughts and behaviors to occur simultaneously with others

Part of your body still knows whats going on

persons ability to become deeply hypnotized; suggestibility

ability to become highly involved in sensory or imaginative sequences

self motivated for hypnotism works best8

skepticism makes it less likely to work
