common misconception: | extinction = ____ the behaviour (ONLY true if reinforcer is attention)
ignoring
27
pitfalls of extinction (2)
(1) distribute attention unwisely (only to problem behaviours) and (2) apply extinction unknowingly to the behaviour of others in your context
28
shaping
development of a new behaviour through reinforcement of successive approximations to a final desired behaviour
29
shaping combines ___ and ____
reinforcement; extinction

intermittent reinforcement is used to ____ behaviour
maintain
37
advantages of intermittent schedules of reinforcement (4)
(1) reinforcer is effective for longer due to slower satiation (especially consummables), (2) behaviour is more resistent to extinction, (3) individuals work more consistently for reinforcement and (4) behaviour will be more readily transfered to control by natural reinforcers in the environment
38
fixed ratio (FR) schedule
reinforcement occurs after set number of responses
39
advantages of fixed ratio (FR) (2)
(1) high resistance to extinction and (2) produces high steady rate of responding (after PRP)
40
post-reinforcement pause (PRP)
no responses immediately after reinforcement; the more responses required to obtain reinforcement, the longer the PRP will be
41
which intermittent reinforcement schedules have a PRP and why?
fixed ratio and fixed interval; because they are predictable
42
ratio strain
increasing the number of responses required for reinforcement too quickly causes deterioration in responses (too rapid of a ratio change)

46
VR maintains behaviour at ____ ratio values than FR
higher
47
VR has ____ resistance to extinction than FR
greater

duration; interval
50
variable interval (VI) schedule
reinforcement produced by the first response after an interval of varying length (averages out)

end
52
advantages of VI (2)
(1) moderately steady rate of response and (2) no PRP

in practice, ____ schedules are less common than ___ schedules because?
interval; ratio because: - FI has long PRP - VI has lower response rate than VR
54
what schedule type is a proposed model for procrastination?

must produce behaviour for full duration (fixed or interval) for reinforcement
65
real example of duration schedule
hourly wage

ABC assessment
identifiying the antecedents and consequences of a behaviour
72
stimulus control
the degree of correlation between the occurence of a particular antecedent stimulus and the occurrence of a subsequent response
73
discriminative stimulus: S^D
a stimulus in the presence of which a resposne will be reinforced; cue that a particular response will pay off (availability of reinforcement)
74
discriminative stimulus: S^delta
a stimulus in the presence of which a response will not be reinforced; cue that a particular repsonse will NOT pay off (non-availability of reinforcement)
75
stimulus discrimination training
the procedure of reinforcing a repsonse in the presence of an S^D and extinguishing that response in the presence of an S^delta
76
effects of stimulus discrimination training (2)
(1) good stimulus control (strong correlation between a particular stimulus and response) and (2) stimulus discrimination

reasons for stimulus generalization (3)
(1) unlearned (strong physical similarity), (2) learned (limited physical similarity) and (3) learned (no physical similarity)
79
conceptual behaviour
emitting appropriate resposnes to all members of a common-element stimulus class and not to stimuli that do not belog to the class (Eg. all red things)

an if-then type of arrangement
83
rule-governed behaviour

84
behaviour chaining
sequence of discriminative stimuli and responses in which each response produced the S^D for the next response with the last response producing a terminal reinforcer (S^r+)
85
link
each S^D->R is a link in the chain; if an R fails to produce a S^D then the chain fails at that point (weak link)
86
methods of behavioural chaining (3)
(1) total task presentation, (2) backward chaining and (3) forward chaining
87
total task presentation
learner attempts to do all the behaivours in the sequence and continues until all steps in the chain are mastered
88
when is total task presentation used?
when sequence is fairly short and simple with discrete tasks (then it's the BEST choice)
89
advantages of total task presentation (3)
(1) teacher spends less time in partial assembly, (2) can produce results quicker and (3) maximizes learner independence (particularily if steps are already familiar)
90
backward chaining
systematically constrct the chain in reverse order starting with the S^D and R that produce the terminal reinforcement
91
advanatage of backward chaining
always stengthening the S^Ds as conditioned reinforcers by associating them with the terminal reinforcement
92
forward chaining
teach inital link first using the terminal reinforcement, then train the initial and second link followed by the terminal reinforcement... and so on
93
what is the most common chaining method in the natural environment?
forward chaining and then total task presentation
94
factors influencing the effectiveness of chaining (6)

97
adventitious chaining
contains response that is not necessary for reinforcement
98
adventitious chaining has a _____ component
superstitious
99
superstitious conponent of adventitious chaining
unnecessary response component that is not functional for reinforecement
100
partial knowledge misapplication in chaining solution
learner learns to make errors when instructor's response is to repeat the question and give answers (engage in an imitation trial) solution: increase reinforcement for correct response on question trials and lower reinforcement for imitation
101
differential reinforcement of low rates (DRL)
only reinforcement if interval between successive responses is >x seconds; goal is to reduce but not eliminate rate of response
102
types of DRL (2)
(1) spaced-responding and (2) limited-responding
103
spaced-responding DRL
requires that a behaviour NOT occur during a specified period/interval, but after interval, a response will produce reinforcement
104
limited-responding DRL
max number of responses taht can occur in an interval, if max is exceeded then no reinforcement is provided
105
differential reinforcement of zero responding/ other responding (DRO)
a reinforcer is presented only if a specified response does not occur during a specified period of time
106
size of DRO should increase until: (2)
(1) behaviour is occuring very rarely/ not at all and (2) a minimum amount of reinforecement is being given for its nonoccurrence
107
differential reinfrocement of incompatible behaviour (DRI)
withholding reinforcers for a target behaviour and reinforcing an incompatible response
108
differential reinforcement of alternative behaviour (DRA)
a procedure that involves the extinction of a problem behaviour combined with reinforcing a behaviour that is topographically dissimilar to, but not necessarily incompatible with, the problem behaviour
109
punisher (aversive stimulus)
an immediate consequence of an operant behaviour that causes that behaivour to decrease in frequency
110
principle of punishment
if, in a give situation, someone does something that is immediately followed by a punisher, then that person is less likely to do the same thing again when she or he next encounters a similar situtation
111
ways "punisher" is different than the common meaning (3)
(1) occurs immediately after the problem behaviour, (2) it is not a form of moral sanction, vengeance or retribution and (3) it is not used to deter others from engaging in the target behaviour
112
types of punishers (4)
(1) physical punisher, (2) reprimand, (3) timeout and (4) response cost
113
physical punishers
stimuli that activate pain receptors (nociceptors) or otherwise cause discomfort (without prior learning)
114
reprimand
a strong negative verbal stimulus immediately contingent on behaviour; generally a conditioned punisher
115
timeout
a period of time immediately following a particular behaviour during which an individual loses the opportunity to earn reinforcers
116
types of timeout (2)
(1) exclusionary and (2) nonexclusionary
117
exclusionary timeout
removing an individual briefly from a reinforcing situation immediately following a behaviour
118
nonexclusionary timeout
introducing into the situation, immediately following a behaviour, a stimulus associated with less reinforcement
119
response cost
immediate removal of a valued stimulus contingent upon a behaviour (negative punishemnt)
120
factors influencing the effectiveness of punishment (5)
(1) maximizing conditions for desirable alternative behaviour, (2) minimizing the cause problem behaviour, (3) selecting punisher, (4) add antecedents for punishment and (5) delivering punisher
121
selecting a punisher (3)
(1) punisher must be effective, (2) potentially a verbal reprimand and (3) effectiveness is increased if the punishment is varied
122
antecedents for punishment (S^DP)
will lead to a faster decrease in problem behaviour and increase in desirable behaviour; rules, warnings... etc
123
delivering punishers (4)
(1) the sooner the better, (2) intermittent punishemnt is LESS effective (be consistent), (3) delivery should not be paired with positive reinforcement (liking for licks; attention) and (4) be calm and matter of fact!!
124
physical punishment is associated with ... (6)
(1) increased aggression, (2) increased antisocial behaivour, (3) poor academic achievement, (4) poor parent-kid relationships, (5) mental health problems and (6) diminished moral internalization
125
in Canada, parents and teachers can use physical punishment with " ___ ___"
reasonable force (no objects or on face)
126
potential harmful side effects of punishment (6)
(1) aggressive behaviour, (2) emotional behaviour, (3) escape and avoidance behaviour, (4) no new behaviour, (5) modeling of punishment and (6) overuse of punishment
127
principle of escape conditioning (negative reinforcement)
the removal of certain, already present, stimuli (aversive stimuli) immediately after the occurrence of a behaviour will increase the likeliood of that behaviour
128
escape extinction
reversing escape conditioning by not allowing the behaviour to cause the aversive stimulus to be removed
129
principle of avoidance conditioning
a contingency in which a behaviour prevents an aversive stimulus from occurring thereby resulting in an increase in the frequency of the behaviour
130
warning stimulus (conditioned aversive stimulus)
stimulus that signals a forth-coming aversive stimulus (in avoidance conditioning)
131
discriminated avoidance conditioning
avoidance conditioing that includes a warning signal that enables the individual to discriminate a forthcoming aversive stimulus
132
respondent behaviour
reflexive; aka unconditioned reflexes
133
unconditioned stimulus
elicits a response (unconditioned response) without prior learning or conditioning
134
conditioned reflex
a stimulus-response relationship in which a stimulus elicits a repsonse because of prior respondent conditioning
135
factors influencing respondent conditioning (5)
(1) greater number of pairings of a CS with an US, the great ability of the CS to elicit the CR, (2) stronger conditioing if the CS precedes the US by about a 1/2 second, (3) a CS acquires greater ability to elicit a CR if the CS is always paired with the US than if it is only occasionally paired with the US, (4) when several neurtal stimuli precede a US, the stimulus that is most consistently associated with the US is the one most likely to become a strong CS and (%) respondent conditioning will devleop more quickly and strongly when the CS or US or both are intense rather than weak
