Perception

Question 1

Is everyone the same? why or why not

Answer 1

no, that is the illusion of perception

Question 2

All mental experiences are _____ and ________ of physical energy.

Answer 2

necessitated; representation

Question 3

Sensation (definition, occurs where)

Answer 3

-the process by which our sensory receptors and nervous system receives and represent stimulus energy from the environment -occurs in peripheral sensory receptor

Question 4

Perception (definition, occurs where)

Answer 4

the selection, organization, and interpretation of sensory input

occurs in the brain

sensory info processed in the cortex

* different parts of the cortex processes certain sensory info

Question 5

Overall generalization of sensation vs perception

Answer 5

Sensation: detect or capture energy/ stimulus energies Perception: interpretation of information from sensation; selects what we are gonna process

Question 6

to feel/ touch (Sense organ and physical energy)

Answer 6

hand/skin; pressure/temperature changes

Question 7

smell (Sense organ and physical energy)

Answer 7

nose ; chemical compounds

Question 8

taste

sense organ and phsycial energy

Answer 8

tongue; chemical compounds

Question 9

Front lobe processes what sensory info

Answer 9

smell

Question 10

temporal lobe processes what sensory info

Answer 10

hearing

Question 11

Parietal lobe processes what sensory info

Answer 11

touch and taste

Question 12

Occipital lobe processes what sensory info

Answer 12

vision

Question 13

Sensory receptors definition

Answer 13

specialized cells in our sense organs that detect sensory stimuli and convert them into neural impulses

Question 14

Transduction

Answer 14

process by which sensory stimuli is analyzed and converted into electrical impulses (action potential); sort of like a translation

Question 15

How do we study perception?

Answer 15

Psychophysics

Question 16

Who was the founder for psychophysics?

Answer 16

Gustav Fechner

Question 17

Psychophysics definiton

Answer 17

the study of the general relationship between physical and perceptual qualities -determines what type of stimuli we can detect and how much (intensity) of that stimuli in order to do so

Question 18

What did Gustav Fechner discover? what is the definition of it?

Answer 18

Absolute threshold -the minimum level of intensity of a stimulus to be registered by the brain 50% of the time as a sensory event

Question 19

What did Ernst Weber discover?

Answer 19

1)determines the difference Threshold for stimuli 2)Webers law

Question 20

Difference threshold (other name; definition )

Answer 20

the difference in physical intensity of a stimulus by adding or substracting to detect a detectable change in sensation 50% of the time

aka Just noticeable difference (JND)

Question 21

Weber’s law

Answer 21

states that JND in a stimulus is a constant proportion of the magnitude of the original stimulus intensity; the amount of change in a stimulus needed to detect a difference in intensity is given by a CONSTANT RATIO or FRACTION of the original stimulus intensity
