that part of the process by which sensations are organized into a meaningful pattern and concept. It is the interpretation of the sensation

Answer 5

Question 6

Perception consists of the psychological stage;

Answer 6

The arousal to consciousness of the sensation

Question 7

sensation refers to the action of some physical stimulus
on a sense organ.

Answer 7

Physical stage

Question 8

For each type of sensation, there is a specific stimulus, that is, one, which is naturally ordained to activate a particular receptor

TRUE OR FALSE

Answer 8

True

Question 9

Dark will activate the eyes; sound will activate the ears, etc.

Answer 9

False

Question 10

is that branch of psychology that studies this relationship between the physical nature of stimuli and a person’s sensory responses to them.

Answer 10

Psychophysics

Question 11

played a central role in the development of the field of psychology, because psychophysics bridges the physical world outside and the psychological world within.

Answer 11

Psychophysics

Question 12

Favorite topics in psychophysics

Answer 12

Stimulus threshold and sensory adaptation

Question 13

is the smallest intensity of a stimulus that must be present to it to be detected

Answer 13

Absolute threshold

Question 14

Hearing?
Taste?
Smell?
Touch?

Answer 14

30mins
20feet
Sugar in 20galloons of water
Three-room apartment

Question 15

■ It is the maximum physical energy, which can still be detected by a sense organ, and beyond which there will be no more sensation, or a sensation of a different modality.

Answer 15

Terminal threshold

Question 16

It is the minimum amount of stimulus energy necessary to
recognize the difference between two stimuli.

Answer 16

The differential threshold

Question 17

It refers to the reduction of sensitivity to stimulation as stimulation persists through time, and to increase in sensitivity with lack of stimulation. Example: at night when there is a brownout, the darkness is at first ‘very dark’ because the eyes were light adapted (hence increased sensitivity to darkness), but after a while the darkness becomes ‘less dark’ because the eyes become dark adapted (hence reduced sensitivity to darkness).

Answer 17

Sensory adaptation

Question 18

process serves as good purpose for people working or residing in environments with unpleasant sensory stimuli, like smell

Answer 18

Sensory adaptation

Question 19

This stage refers to the physiological process that start with the action of the stimulus on a receptor, which then triggers a flow of nerve impulses from the receptor to some terminal point in the nervous system.

Answer 19

PHYSIOLOGICAL STAGE of the SENSATION

Question 20

refers to the different categories of a sensation making, for instance a visual (colors) sensation different from an auditory (sound) sensation.

Answer 20

Answer 22

Intensity

Question 23

indicates the length of time a sensation lasts in the consciousness.

Answer 23

Duration

Question 24

refers to the time interval between the application of a sensory stimulus on a sensory receptor and the recognition of this sensory experience is manifested in a reaction by the subject.

Answer 24

Reaction time

Question 25

Answer 25
