Coding of Information

Question 1

feature of a stimulus that is visual, auditory, olfactory, gustatory, somatosensory, balance, proprioceptive

Answer 1

modality

Question 2

feature of a stimulus where it is in space and relative to other things

Answer 2

location

Question 3

feature of a stimulus that is saturation / how loud the tone is

Answer 3

intensity

Question 4

feature of a stimulus that is dynamically changing and can be due to movement

Answer 4

duration

Question 5

a funciton that describes the relationship between the physical properties of a stimulus and perceptions

Answer 5

psychometric function

Question 6

50% of people can detect a stimulus at this level

Answer 6

detection threshold

Question 7

two alternative forced choice task

Answer 7

signal detection theory

Question 8

perception is also driven by stimulus blank

Answer 8

complexity

Question 9

an index of the complexity of perceptual/cognitive processes

Answer 9

response speed

Question 10

the blank is what gives rise to perceptions… and actually is a perception in itself

Answer 10

neural code

Question 11

neural coding pathway

Answer 11

sensory –> signal transduction –> sensory systems –> relay systems –> cognitive/conceptual systems

Question 12

three types of sensory receptors

Answer 12

photoreceptors, chemoreceptors, mechanoreceptors

Question 13

neural coding begins with ap toward CNS

Answer 13

signal transduction

Question 14

high frequencies are processed at blank end

Answer 14

basal

Question 15

low frequencies are processed at the blank end

Answer 15

apical

Question 16

sensory neurons have receptive fields that correspond to blank localization of stimuli

Answer 16

spatial

Question 17

stimulation of the sensory neuron downstream from the sensory receptor will still elicit a blank of blank in that receptive field

Answer 17

perception, sensation

Question 18

these neurons have larger receptive fields and begin the process of integrating information across sensory neuron

Answer 18

second order

Question 19

individual neurons can code information via blank

Answer 19

firing rates

Question 20

information coded in individual firing rates can be collected in multiple neurons and blank integrated to create a blank code

Answer 20

population

Question 21

as sensory pathways go more central, more features of the stimuli are blank to form the neural basis

Answer 21

integrated

Question 22

this modulates sensory input and alters perceptual constructs

Answer 22

context

Question 23

four features of a stimulus

Answer 23

modality, location, intensity, duration
