Sensory systems gather info from?

External stimuli

1

The perceptual system builds ....

Models

2

Transduction involves taking energy and converting it into ....

Nerve messages

3

Detecting physical stimuli by sensory receptors is

Sensation

Example it is lines,shape,contoured

4

The building of models, organizing and interpreting of sensory info . It allows us to detect meaningful objects is called

Perception

Example it's a desk

5

Being influenced by actual stimulus at the sensory receptors is

Bottom up processing

6

Being influenced by experience,expectation,knowledge,belief, an other things is..

Top down processing

Ex. Nursing on wounds

7

The smallest change we as humans can detect between any two stimuli half the time is called

Difference threshold or just-noticeable-difference

8

The smallest amount of stimulus detected 50% of the time

Absolute threshold

9

Under 50% of stimulus is detected

Subliminal stimuli

10

Change needed is a constant proportion ( constant percentage) is stated by what law

Weber law
Light - 8%
Weight- 2%
Tone- .2%

11

Thresholds are (blank) and sensory adaptation is (blank)

Detected,not detected

12

The conversion of one form of energy to another is

Transduction

13

Perception is to (blank) as sensation is to (blank)

Bottom up processing........top down processing

14

A theory predicting how and when we detect the presence of a faint stimulus and background stimulation

Signal detection theory

15

The activation, often unconsciously, of certain associations that predispose one's perception,memory, or response

Priming

16

What does the visual system do to ensure constant Change in stimulation?

The eyes quiver

17

A frame of mind or mental tendency is

Perceptual set

18

Misheard lyrics,spelling and reading, and talking are examples of what?

Top down processing

19

Things about us that shape models is what type of processing

Top down processing

20

Stimuli and sensory receptors that shape our models are

Bottom up processing

21

Who suggested that "the whole is more than the sum of its parts"?
An example is the pixels of a tv showing us images

The gestalt psychologists

22

When the figure stands out from its background

Contour

23

Wearing camouflage when hunting to not be seen is an example of not wanting any

Contour

24

The face and vase picture and the old lady and young lady are examples of

Reversible figures

25

When a figure becomes the ground and the ground becomes the figure is called

Reversible figures

26

Proximity,similarity, and closure deal with

Grouping

27

When objects grouped together are seen as a whole

Closure

28

When Objects near each other are grouped together it is called

Proximity

29

Contrast can be influenced by what?

Nearby stimuli

30

Monocular cues are used to see what 4 things

1) linear perspective
2) inter positions
3) relative height
4) relative size

31

Monocular cues use ( blank )

One eye

32

Making objects larger or smaller so they appear closer or farther. An example is painting blocks on Cinderella's castle

Forced perspective

33

3D includes

Depths,width, and height

34

When things appear to be overlapping are in

Interposition

35

Binocular cues need

Both eyes!!

36

Close objects have ( blank) retinal disparity and far away objects have ( blank) retinal disparity

Increase,less

37

People with ( blank) threshold are less likely to seek out the correct detections of stimuli.

Low

38

We can detect subliminal sensation but not be long term persuaded by

Subliminal persuasion

39

Sensory adaptation also us to pick out the important details and to forget about the

Not so important details

40

Schemas affect how we

Interpret things
Ex baby in none gender defying clothes,when told his name is David we now see him as a boy

41

If you move your watch band up your wrist an inch or so you will only feel it for a few moments. This is called

Sensory adaption

42

The minimal difference between two stimuli required for 50 percent of the time is called

Just noticeable difference

43

The conversion of fresh coffee aroma into neural impulses by olfactory receptor cells best illustrates

Transduction

44

Perception is a process by which

Sensory input is organized and interpreted

45

Interpreting New sensory info within the framework of past memory illustrates

Top down processing

46

The constant quivering movements of our eyes enables us to

Minimize sensory adaption

47

Which of the following represents the very first of three steps basic to all sensory systems

Receiving sensory stimulation

48

The local fire department sounds the 12 o'clock whistle. The process by which your ears transform the sound waves from siren into neural impulses is an example of

Transduction

49

When Rick learned that many students had received failing grade on their mid terms he was no longer dis appointed by his c this represents

Context effects

50

Webers's law states

The just noticeable difference for any stimulus is a constant proportion

51

Hearing a sequence of sounds of different pitches is to — as recognizing the sound sequence as a familiar melody is to—

Sensation,preception

52

A perceptual set is

Mental predisposition that influences what we perceive

53

Sensation is to — as perception is to —

Detection,interpretation
Bottom up processing, top down processing

54

After hearing rumors about the outbreak of an infectious disease, alyosha began to perceive his normal aches and pains as disease- related symptoms. His reaction best illustrates

Perceptual set

55

Given normal sensory ability a person standing atop a mountain on a dark clear night can see a candle flame 30 miles away this illustrates

Absolute threshold

56

A subliminal message is one that is presented


Below ones absolute threshold of awareness

57

Sensory adaption helps us focus our attention on — stimuli

Novel

58

Bottom up processing involves analysis that begins with the

Sensory receptors

59

Giulio's bag of marbles is twice as heavy as Jim's. If it takes 5 extra marbles to make Jim's bag fee heavier it will take 10 extra marbles to make Giulio's bag feel heavier. This illustrates

Webers law

60

A decrease in sensory responsiveness accompanying a unchanging stimulus is called

Sensory adaption

61

Perceptual se involves
