Sensation And Perception- Kaplan

Front 1

Bekesy

Back 1

Empirical studies led to traveling wave theory of pitch perception which, at least partially, supported Helmholtz's place resonance theory

Front 2

Berkeley, G

Back 2

Developed depth cues that help us to perceive depth

Front 3

Broadbent

Back 3

Proposed filter theory of attention

Front 4

Filter theory of attention

Back 4

Broadbent, probably not a correct theory, thought that attention is all or nothing; if we attend to something we don't attend to anything else.

Front 5

Place resonance theory

Back 5

Helmholtz's theory that the part of the frequency of the sound determines what part of the basilar membrane vibrates

Front 6

frequency theory

Back 6

The basilar membrane vibrates as a whole and it's the rate of vibration that reflects the frequency of the sound.

Front 7

Fechner's Law

Back 7

Fechner's Law- expresses the relationship between the intensity of the stimulus and the intensity of the sensation. sensation increases more slowly as intensity increases

Front 8

Steven's Power law

Back 8

sensation to intensity law. suggested Fechner was incorrect
Weber= 1 to 1
Fechner = .5 to 1
Stevens= prob something exponential

Front 9

Gibson E. and Walk, R.

Back 9

Visual cliff to study depth perception

Front 10

Gibson, J

Back 10

Studied depth cues especially texture gradients that help us to perceive depth

Front 11

Helmholtz, H.

Back 11

Young-helmholtz trichomatic theory of color vision; also place theory of pitch perception

Front 12

Hering, E.

Back 12

Developed opponent process theory of color vision- red-green, blue-yellow, black-white

Front 13

Hubel and Wiesel

Back 13

Studied feature detection in visual cortex and discovered simple (orientation and boundaries), complex(movement), and hypercomplex(object shape) cells. Revoltionary that 1 type of cell detects one feature of an object

Front 14

Interposition, relative size, Linear perspective

Back 14

Depth perception cues found by Berkeley- Overlapping obeject seems closer, smaller objects are farther from seer, convergence of parallel lines to percieve depth

Front 15

Kohler, W.

Back 15

Developed theory of isomorphism- there is an exact replication of the objects in the visual field in the brain

Front 16

Weber, E.

Back 16

Just noticeable difference- point at which you can see, hear 2 stimuli are different

Front 17

Melzack and Wall

Back 17

Proposed gate theory of pain- special gating system to turn pain on and off

Front 18

Phi Phenomenon

Back 18

Wertheimer- cause him to come up with gestalt psychology- when two lights flicker in proximity, the brain perceives it as one moving light

Front 19

Sir Francis Galton

Back 19

looked at 10,000 people's different sensory abilities

Front 20

Signal detection theory

Back 20

there are certain response biases that also effect how someone performs in sensory tests. Like how sure they need to be before responding

Front 21

John Swets

Back 21

ROC for signal detection theory

Front 22

Visual brain centers

Back 22

Superior colliculus, occipital lobe, lateral geniculate nucleus of the thalamus

Front 23

Wever E. and Bray C

Back 23

Proposed volley theory of pitch perception in response to criticism of the frequency theory of pitch perception

Front 24

Yerkes and Dodson

Back 24

Performance best at intermediate levels of arousal

Front 25

brain parts associated with the auditory system

Back 25

superior olive, inferior colliculus, medial gen nucleus of the thalamus, temporal cortex
