Sensation and Perception

Question 1

Synesthesia

Answer 1

Some people experience intermixing of two or more sensory systems E.g. when you hear the word “river”

Question 2

A person who has this form of synesthesia always sees colour in response to a specific letter or number E.g. the number 9 is always perceived as turquoise

Answer 2

Grapheme-colour synesthesia

Question 3

What are the two closely related processes involved in sensory perception

Answer 3

Sensation and Perception

Question 4

sensation

Answer 4

The act of using our sensory systems to detect environmental stimuli

Question 5

what do you call the physical energy from environmental to electrical signals for the brain

Answer 5

transduction

Question 6

Perception

Answer 6

The conscious recognition and identification of a sensory stimulus

Question 7

sensory receptor cells

Answer 7

specialized cells that convert a specific form of environmental stimuli into neuron impulses

Question 8

The PROCESS of converting a specific form of environmental stimuli into neural impulses (the process of sensory receptor cells)

Answer 8

Sensory transduction

Question 9

Threshold

Answer 9

A stimulus must reach a certain amount of intensity before we can detect it

Question 10

Absolute Threshold

Answer 10

The minimal amount of stimulus needed to be detected by an individual

Question 11

The minimal difference between two stimuli necessary for the detection of a difference between the two

Answer 11

Difference Threshold or Just Noticeable Differences

Question 12

Give an example of an absolute threshold for olfactory

Answer 12

a drop of perfume diffused throughout a six-room apartment

Question 13

olfactory 
somatosensory 
Gustatory
Visual
Auditory

Answer 13

smell
touch/pain/heat
taste
sight
hearing

Question 14

sensory adaption

Answer 14

the process whereby a repeated stimulation of a sensory cell leads to a reduced response (getting used to a bad smell)

Question 15

Processing sensory Information: bottom-up processing

Answer 15

The perception that proceeds by transducing environmental stimuli into neural impulses that move into excessively more complex regions

Question 16

Top-down processing

Answer 16

Perception processes led by cognitive processes, such as memory or expectations

Question 17

readiness to interpret a certain stimulus in a certain way. For example, consider whether a dish would taste good if you thought the dish was chicken or rattlesnakes

Answer 17

Perceptual Sets

Question 18

Ambiguous Stimuli

Answer 18

Stimuli that could be interpreted in different ways. For example, what you see in a drawing is what you expect to see

Question 19

_____ are part of the nervous system consisting of sensory receptors that receive stimulus information and conduct information to parts of the brain responsible for processing sensory information

Answer 19

Sensory system
