lecture 5

Question 1

Define stimulus control

Answer 1

degree of correlation between occurence of particular antecedant stimulus and occurence of a subsequent response

Question 2

define stimuli

Answer 2

people, objects or events that are currently present in one’s immediate surroundings that impinge on senses and affect behaviour

Question 3

ABC assesment

Answer 3

Antecedent, behaviour, conseqeunces

Identifying the antecedents and consequences of a behaviour

Question 4

Discriminative stimulus

Answer 4

SD- Stimulus in the presence of which an operant response will be reinforced

cue that a response will pay off

Question 5

extinction stimulus

Answer 5

S-Delta
stimulus in the presence of which an operant response will not be reinforced

Cue that a response will not pay off

Question 6

example sd

Answer 6

SD: Other kids Response: swearing - reinforcer : social approval

Question 7

example s-delta

Answer 7

Sdelta: Grandparents present- Response: Swearing- Reinforcer- No positive attention

Question 8

Operant stimulus discrimination training

Answer 8

procedure of reinforcing a response in the presence of an SD and extinguishing that response in the presence of an Sdelta

Question 9

good stimulus control

Answer 9

is a result of operant stimulus disc training

= a strong correlation between occurence of a particular stimulus and a particular response

Question 10

stimulus discrimination

Answer 10

is also a result of operant stimulus disc training

response occurs to an Sd and not an Sdelta

Question 11

operant stimulus generalization

Answer 11

refers to the procedure of reinforcing a response in the presence of a stimulus or
situation and the effect of the response becoming more probable not only in the presence of that stimulus or situation,
but also in the presence of another stimulus or situation.

Question 12

learned stimulus class

Answer 12

learning concept of stimulus class, two things that are not very similar sharing a class i.e. german shepherd chiuaua are both dogs but that has to be learned, limited physically similar

Question 13

stimulus equivalence class

Answer 13

completley dissimilar stimuli which an individual learns to group or match together

ex. different representations of number 3

3, three, III

Question 14

rule governed bh

Answer 14

controlled by statement of rule

Question 15

contingency governed bh

Answer 15

controlled by trial and error

Question 16

possible pitfalls of operant stimulus disc training

Answer 16

unaware misapplication pitfall
=accidentally reinforcing Sdelta instead of requiring and reinforcing responses to SD

Question 17

define fading

Answer 17

gradual change over successive trials of an antecedent stimulus that controls a response, so that the response eventually occurs to a changed or completely new antecedent

Question 18

Define prompts

Answer 18

supplemental antecedent provided to increase likelihood that a desired bh will occur (but not the final target stimulus)

Question 19

Physical Prompt?

Answer 19

Guiding learning thru physical touch e.g. parents holding childrens hand to teach walking

Question 20

Environmental Prompt

Answer 20

env alteration which evokes desired bh

Question 21

extra stimulus prompt vs within stimulus prompt

Answer 21

ES = Added to env
WS= variation of SD or sdelta that makes it more noticeable

Question 22

dimensions of stimulus

Answer 22

characteristics of stimulus that can be measured

ex volume of speech, pressure of touch

Question 23

define behavioural chain aka stimulus response chain

Answer 23

is a consistent sequence of stimuli and responses that occur closely to each other in time and in which the last response is typically followed by a reinforcer.

each response porudces a stimulus which serves as SD

sd1>r1>sd2>r2> S+

s+= reinforcer

Question 24

difference between behaviour chains and sequences

Answer 24

bh sequence is more varied with breaks

ex studying for a final

study, sleeping, breaks, reading, memorizing, etc — not a chain of stim and resp

Question 25

total task presentation

Answer 25

an individual attempts
all of the steps from the beginning to the end of the chain on each trial and continues with total-task trials until he/she learns the chain

Question 26

backward chaining

Answer 26

method, the last step is taught first, then the next-to-last step is taught and
linked to the last step, then the third-from-last step is taught and linked to the last two steps, and so on, progressing backward toward the beginning of the chain

Question 27

forward chaining

Answer 27

teaches the initial step of the sequence first, then teaches and links together the
first and second steps, then the first three steps, and so on until the entire chain is acquired

Question 28

ttp reinforcer applied?

Answer 28

at last step

Question 29

fc and bc reinforcer applied

Answer 29

at step that is being taught

Question 30

task analysis

Answer 30

process of breaking down a task into smaller steps or component responses to facilitate training
