25
what is least to most prompting?
fading across prompts. involves using least intrusive prompts first and uses more intrusive prompts as necessary (increase assistance)
26
what is most to least prompting?
this is fading across prompts. most intrusive prompt is used first and then faded to less intrusive methods (decrease assistance)
27
what is prompt delay?
presenting the SD, wait, and then if the correct response is not maybe, you provide the prompt
28
what does the first trial begin with in prompt delay?
first trial always beings with 0 second delay between the SD and the prompt
29
what is stimulus fading?
whenever stimulus prompts are used to get a correct response to occur, some aspect of the SD or the stimulus situation is changed help the person make the correct discrimination. eventually stimulus prompts must be removed through stimulus fading to transfer stimulus control to the natural SD
30
what is a learning trial?
sequence of presenting the SD, prompting the response, and providing a reinforcer
31
what is a behavioural chain
complex behaviour consisting of many component behaviours that occur together in a sequence
32
what is a behavioural chain often called? why?
stimulus response chain, each behaviour or response in the chain produces a stimulus chaine that acts as an SD for the next response in the chain
33
what is the whole chain under
stimulus control
34
how can you make the outcome of a chain more reinforcing?
adding an establishing operation
35
what is a task analysis
process of analyzing a behavioural chain by breaking it down into its individual stimulus-response components
36
what is a chaining procedure?
strategies for teaching complex tasks
37
what is backwards chaining?
use prompting and fading to teach the last behaviour of the chain first. used most often with limited abilities
38
what is forward chaining?
teach the first component first, then move on
39
what happens in backward chaining
you complete the task in every learning trial
40
what is total task presentation?
complex chain of behaviours is taught as a single unit
41
what is graduated guidance
often used with total task, uses hand over hand guidance. provides less and less assistance and as the learner completes the task. ex shadowing or spatial fading
42
what is a written task analysis?
trainer presents the learner with a list of the component behaviours in their order and the learner uses this list to perform the task correctly
43
picture prompts
take pictures of the outcome of each behaviour or of someone engaging in each behaviour in the task
44
video modeling
learner watches a video of someone engaging in the chain of behaviours immediately before engaging in the same task
45
self instructions
self generated verbal prompts
46
what is a single opportunity method in chaining?
present the learner with the opportunity to complete the task and record which components the learner completes without assistance in the correct sequence
47
what is a multiple opportunity method in chaining?
assess learners ability to complete each individual component in the chain until the learner has had the opportunity to respond to every SD in the chain
48
functional assessment
process of identifying antecedent and consequent variables before treating a problem behaviour. is always the first step in using bmod procedures
49
4 classes of the functions of problem behaviours
social positive reinforcement, social negative reinforcement, automatic positive reinforcement, automatic negative . Lecture: tangible and activity
50
what are 3 types of functional assessment methods?
indirect assessment, direct observation methods, experimental methods
51
what are indirect methods?
behavioural interviews and stuff. relies on the memories of events. used commonly because of convenience
52
what is the direct observation method? what are they also called? what does it not demonstrate?
person observes and records the antecedent and consequences each time the problem behaviour occurs. also called ABC observations. does not demonstrate a functional relationship
53
what is the desired outcome of an ABC observation?
development of a hypothesis about the antecedents and consequences of a desired outcome
54
what are 3 ways ABC observations can be conducted?
descriptive method, checklist method, interval/real time recording method
55
what is the descriptive method?
observer writes a brief description of the behaviour and antecedent and consequences. can be conducted before any hypothesis are made
56
what is the checklist method?
involves a checklist with columns for possible antecedents, behaviours and consequences. usually developed after antecedents and consequences and behaviour have been identified
57
what is the interval/ real time recording method?
divide observation period into brief times, mark each interval
58
what can direct and indirect methods be categorized together as?
descriptive assessments
59
what is the experimental method/functional analysis?
manipulating the antecedent and consequent variables to demonstrate their influence on a problem behaviour. usually demonstrates a functional relationship
60
how does an exploratory functional analysis work?
involves 3/4 test conditions and a control. present EO and reinforcers for test conditions and AO and no reinforcer for control
61
what is a exploratory functional analysis designed for?
to identify a particular function of a problem behaviour while ruling out other functions
62
how does a hypothesis-testing functional analysis work?
used not to evaluate all possible functions, but to confirm or disconfirm hypothesis. one test condition and one control
63
what are functional interventions designed to do and what do they include?
designed to alter the antecedents and consequences of the problem behaviour to decrease it. includes extinction, differential reinforcement, and antecedent manipulation
64
to apply extinction, what should you first do?
identify the reinforcer that maintains the problem behaviour and then eliminate it
65
what should an extinction procedure always be used in conjunction with? why?
a reinforcement produce to increase an alternative behaviour to replace the problem behaviour
66
what are the three types of differential reinforcement?
differential reinforcement of alternative behaviour, differential reinforcement of other behaviour, differential reinforcement of low rates of responding
67
what is DRA?
differential reinforcement of alternative behaviour. used to increase the frequency of a desirable behaviour and to decrease the frequency of an undesirable behaviour
68
what is a preference assessment?
trying out a variety of stimuli and seeing which ones the person prefers
69
what is reinforcer assessment
to determine that the item did in fact function as a reinforcer
70
what is single stimulus assessment
each potential reinforcer is presented, one at a time, to see where the individual approaches the stimulus
71
paired stimulus assessment
two potential reinforcers are presented to the individual and researchers records which stimulus individual approaches
72
multiple stimulus assessment
array of potential reinforcers are presented to the individual and researcher records with stimulus the individual approaches
73
what are two variations of DRA?
differential reinforcement of an incompatible behaviour (DRI), and differential reinforcement of communication (DRC)
74
Differential reinforcement of an incompatible behaviour (DRI)
Alternative behaviour is physically incompatible with the problem behaviour, and therefore the two behaviours cannot occur at the same time
75
Differential reinforcement of communication (DRC)
Alternative behaviour that is reinforced to replace the problem behaviour is a communication response. uses functional communication training
76
Differential reinforcement of other behaviours (DRO)
in DRO, you are reinforcing the absence of a behaviour. the reinforcer is delivered only after periods in which the problem behaviour is absent
77
whole interval DRO
the problem behaviour must be absent for the whole interval to be reinforced
78
momentary DRO
problem behaviour must be absent at the end of the interval for the reinforcer to be delivered
79
Differential reinforcement of low rates of responding (DRL)
Reinforce lower rate of behaviour
80
full session DRL
reinforcement is delivered if fewer than a specified number of responses occur in a period of time
81
spaced responding DRL
there must be a specified amount of time between responses for the reinforcer to be delivered
82
interval DRL
Involves dividing a session into intervals and providing the reinforcer if no more than one response occurred in each interval
83
what is stereotypic behaviour
repetitive behaviour that does not serve any social function for the person
84
antecedent control procedures
manipulation some aspect of the physical or social environment to make a desired behaviour more likely or to make a competing, undesirable behaviour less likely
85
what are 3 antecedent manipulations that evoke a desired response?
presenting SD or cues for the desired behaviour, arranging EOs for the desirable behaviour, decreasing response effort for the desirable behaivour
86
what are 3 antecedent manipulations that make undesirable competing responses less likely?
removing SD or cues for undesirable behaviour, presenting AOs for undesirable behaviour, increase the response effort for undesirable behaviours
87
quantitative shaping
setting criteria to increase or decrease the amount of behaviour
88
qualitative/topographic shaping
degree to which successive behaviours resemble the target behaviour
89
three step prompting
use prompts progressively, starting with verbal, then modeling, and finally physical guidance prompts
90
what are the 5 types of stimulus prompts?
within stimulus, extra stimulus, pictorial, auditory, environmental
91
what is fading within prompts
same prompt s used, but decreased in magnitude or intensity
92
what is fading across prompts?
prompt is changed, according to a prompting hierarchy
93
non contingent reinforcement (NCR)
type of antecedent intervention in which stimuli that are known reinforcers are delivered on a schedule independent of behaviour (not dependent on responses). diminishes undesirable behaviours because reinforcers that maintain it are frequently available. may function as AO
