Unit 3

Question 1

Perception

Answer 1

interpretation of the info we obtain through our 5 sense

Question 2

Bottom up processing

Answer 2

takes all sensory info to the brain for processing

Question 3

Sensory transduction

Answer 3

process where you take all the stimuli and it’s translated into neural energy

Question 4

Sensation

Answer 4

info we receive from our 5 senses

Question 5

Transducers

Answer 5

receptor cells that convert the stimuli into neural energy

Question 6

Absolute threshold

Answer 6

minimum amount that can be detected 50% of the time

Question 7

Signal Detection Theory

Answer 7

there are psychological reasons that we’re able to detect

Question 8

Difference threshold

Answer 8

just noticeable difference - measures the difference threshold - needs to be 2%
how much stimuli changes before we notice

Question 9

Weber’s law

Answer 9

not the amount changed but the percentage
the larger and stronger stimuli the more changes needed to detect the difference
ex:sweet tea, loud music

Question 10

Sensory activity

Answer 10

accuracy of our senses

Question 11

Perceptual Set

Answer 11

a way we process the world based off experience, context, motivation, etc

expectations

Top down processing

Answer 12

starts at the brain
uses context, prior knowledge to give something meaning

Question 13

Inattention Blindness

Answer 13

become so focused we miss other things

Question 14

Sensory adaption

Answer 14

receptor cells
decline in receptor activity when stimuli is unchanging
ex: getting use to a cold pool
