sensing , responding and learning

Question 1

stimulus elicited behaviour

Answer 1

involuntary and relatively immediate consequence of sensory stimulation
response to a stimulus

Question 2

eliciting stimulus

Answer 2

any stimulus that is effective at evoking a particular behavioural response

Question 3

animals do things by

Answer 3

contracting their muscles and move their bodies - examples of motor behaviours

Question 4

behaviours must be

Answer 4

initiated in some way

Question 5

how are behaviours initiated

Answer 5

internally initiated behaviour

stimulus elicited behaviour

Question 6

internally initiated

Answer 6

by something happening within the nervous system - act of will - voluntary

Question 7

reflex

Answer 7

stimulus elicited behaviour elicited by proximal stimulation

involuntary response to an eliciting stimulus

Question 8

example of reflex

Answer 8

pupillary light reflex - pupils dilate in responses ti a decrease in light levels and constrict a response to an increase

Question 9

autonomic reflex

Answer 9

one mediated by the ANS

controls smooth muscles , glands and cardiac muscle

Question 10

skeletomotor reflex

Answer 10

not autonomic - involves miles that move the skeleton

Question 11

what distinguishes a reflex from other types of stimulus elicited behaviour

Answer 11

it depends on the type of stimulus - proximal and distal

Question 12

proximal stimulus

Answer 12

energy that stimulates sensory receptors

eg light energy stimulating receptors in the eye

Question 13

distal stimulus

Answer 13

objects , events , states of affairs in the world
a perceived object are the sources
eg- mechanical forces distort tissues

Question 14

The NS does not need to

Answer 14

identify , recognise or obtain any info about a distal

Question 15

if the behaviour response is elicited by a distal stimulus

Answer 15

then the behaviour is NOT a REFLEX

Question 16

two basic roles that stimulus can play in the elicitation of behavioural responses

Answer 16

releasing mode of elicitation

driving mode of elicitation

Question 17

releasing mode of elicitation

Answer 17

the stimulus TRIGGERS the response in a discrete fashion- response is stored beforehand and the stimulus releases it

Question 18

driving mode of elicitation

Answer 18

the stimulus DRIVES the response in a continuous fashion

Question 19

stimulus released responses are independent of

Answer 19

independent of the intensity - response is the same size regardless of strength

Question 20

driving mode strong -

Answer 20

strong/ intense = large response

size of response is dependent of the strength

Question 21

driven mode duration

Answer 21

if the eliciting stimulus persists the resins persists

Question 22

driving mode amplitude

Answer 22

if the eliciting stimulus is intense/ strong , response is larger

Question 23

variation driving mode

Answer 23

if the eliciting stimulus strength increases and decreases response vigour increases and decreases

Question 24

releasing mode size of response

Answer 24

all or nothing principle
