23
Q

multiple control

A

when bx is maintained by more than one type of consequence

24
Q

reasons for undifferentiated patterns of bx during functional analysis

A
  • difficulties discriminating the different conditions
  • relevant variables are not included in the conditions
  • multiple control
25
Q

ways to clarify functional analysis results

A
  • enhance motivational operations
  • enhance discriminability
  • limit number of topographies being assessed
  • modify the control condition
26
Q

variables that might present problems to the use of functional analysis

A
  • time limitations
  • severity of problem bx
  • assessment in naturalistic settings
  • low rates of bx
27
Q

considerations before conducting a functional analysis

A
  • do benefits outweigh potential risks?
  • are protective procedures in place?
  • is a controlled setting available?
  • are there sufficient trained staff available?
28
Q

limitations of functional analysis

A
  • failure to identify the full range of the controlling variables or failure to identify the specific features that evoke problem bx
  • potential iatrogenic effects
  • time and labor intensive
  • contrived situations may not simulate what occurs in the natural environment
29
Q

functional analysis conditions variations

A
  • alter response measurement
  • enhance motivational operations
  • use discriminative stimuli
  • vary the control condition
30
Q

functional analysis design variations

A
  • brief functional analysis
  • extended alone conditions
  • pairwise comparisons
31
Q

severity assessment

A

“a method for classifying and quantifying surface damage caused by self-injurious bx”

32
Q

estimates of severity assessment

A
  • location of tissue damage
  • type of tissue damage
  • number of damaged areas
  • severity of tissue damage
33
Q

uses of severity assessment

A
  • before treatment, establishes bx that warrants serious attention
  • estimates the risks associated with SIBd
  • after treatment, corroborates/validates effectiveness of interventions
  • provides a secondary means of assessing treatment maintenance or compliance with treatment recommendations
34
Q

preference assessment

A

method for id’ing individual’s preferences among various items, events, and activities

35
Q

approaches to preference assessment

A
  • indirect (informant-based) methods
  • naturalistic (in vivo) direct observation
  • reinforcer sampling procedures (empirical)
36
Q

reinforcer sampling

A

a systematic preference assessment method to expose individuals to, or provide an individual with, a variety of stimuli or activities and measuring which are preferred.

37
Q

types of preference assessment

A
  • selection-based preference assessment

- duration-based preference assessment

38
Q

selection-based preference assessment

A

reinforcer sampling procedure in which items are presented systematically to produce preference hierarchies.

39
Q

types of selection-based preference assessment

A
  • single-item/approach method (single-stimulus assessment)
  • paired choice (forced-choice)
  • multiple stimulus (with or without replacement)
40
Q

Single-item/approach method (single-stimulus assessment)

A

Reinforcer sampling procedure in which items are presented, one at a time, in front of the person, and it is measured whether or not they were approached. Preference hierarchy is based on the number of times an item was approached given the number of times it was presented.

41
Q

Paired-choice (forced-choice) preference assessment

A

Reinforcer sampling procedure in which items are presented, two at a time, in front of the person, and it is measured which item was approached. Preference hierarchy is based on the number of times an item was selected given the number of times it was presented.

42
Q

Multiple-stimulus preference assessment

A

Reinforcer sampling procedure in which all items are presented simultaneously. Participants select one from among all items during each trial.

43
Q

Types of multiple-stimulus preference assessment

A
  • With replacement

* Without replacement

44
Q

Multiple-stimulus with replacement

A

Multiple-stimulus preference assessment in which participants select an item from an array. This same array is presented multiple times.

45
Q

Multiple-stimulus without replacement

A

Multiple-stimulus preference assessment in which participants select an item from an array. The items selected are removed from the array, and this procedure is repeated until all items have been selected from the array

46
Q

Duration-based preference assessment

A

Preference assessment in which items are presented to the individuals and the proportion of time spent engaging the items is recorded as a measure of preference.

47
Q

Types of duration-based preference assessment

A
  • Single item presentation
  • Free operant (or multiple item) assessments
  • Competing stimulus preference assessment
48
Q

Single-item presentation (duration-based preference assessment)

A

Duration-based preference assessment in which each item is presented individually several times and the amount of time spent engaging the item is recorded as a measure of preference.

49
Q 
Free operant (or multiple item) assessment
(duration-based preference assessment)
A

Duration-based preference assessment in which all items are presented simultaneously and the amount of time spent engaging with each item is recorded as a measure of preference.

50
Q

Competing stimulus preference assessment

A

Duration-based preference assessment used to determine the extent to which stimuli displace problem behavior.

51
Q

Reinforcer assessment

A

“A variety of direct, empirical methods for presenting one or more stimuli contingent on a target response and measuring their effectiveness as reinforcers.”

52
Q

Types of reinforce assessments

A
  • Single-operant arrangement

* Concurrent operant arrangement

53
Q

Single-operant arrangement

A

Reinforcer assessment in which the reinforcer efficacy of a single item is tested by comparing levels of a response when it is delivered as a consequence to levels observed during baseline (no consequence).

54
Q

Concurrent operant arrangement

A

Reinforcer assessment in which a concurrent schedule is used to compare the relative strength of two or more reinforcers

55
Q

False negative

related to preference assessment

A

Failure to identify an item as a reinforcer because it ranks low in a preference assessment.
