Q

Functional Analysis E.g.

A

*Is Bx (screaming) maintained by socially mediated positive Rx in the form attention (reprimands) ?
-Condition A (test):
Scream - attention (reprimand)
-Condition B (Control):
-Scream - No attention
*Higher levels of Bx in test when compared to control suggests attention may be a reinforcer for this bx

  • Always graph each topography separately
  • If necessary, place some topographies on extinction until all topographies emerge
76
Q

What are the limitations of including multiple response topographies in a single functional analysis?

A
  • May not observe all topographies during the assessment
  • Potentially less efficient
  • Different topographies could have different functions

-Allow prob bx to subside btw sessions
Reduces potential carryover effects

89
Q

When analyzing the data from a functional analysis, how do we determine the maintaining variable?

A

-Conditions with high rates compared to the control are likely maintaining bx

98
Q

Identify the continuous measures commonly used in a functional analysis:

A
  • Latency

- Rate

99
Q

A
  • Ideally separate functional analyses for each topography
  • Often not practical
  • Graph together only if suspected to be maintained by same contingency
  • Generally speaking, better to graph separately
101
Q

Alternatives to Separate Functional Analyses for Each Topography

A
  • Conduct one functional analysis of multiple topographies, graph as aggregate & separate
  • Reduces time, cost and inconclusive results
  • Conduct an extinction analysis
102

Q

Extinction Analysis in the literature: Richman et al. (1999) Phase 2

A
  • Only 1 topography was reinforced, all others placed on Extinction
  • If reinforcer was not provided right after initial/ mild problem bx, the client would try a different (typically more severe) topography of prob bx
108
Q

Take-Home Points

A
  • When consequences are provided for multiple topographies of problem bx, interpretation can be difficult
  • It is best to reinforce only 1 topography per functional analysis when possible; if this is not practical it is recommended to always Graph topographies separately
109
Q

The Language We Use and What it Means

A
  • “The bx is maintained by attention”

* “Attention is the function of the bx”

110
Q

Attention

A
  • Attention can function as a type of socially mediated positive reinforcement
  • Behavior results in access to attention from others
111
Q

Attention as a Function:

*Problem bx maintained by attention maybe likely to occur:

A
  • When bx not getting enough attention (infrequent attention)
  • When others are preoccupied (divided attention)
  • When bx lacks functional communication (difficulty communicating wants & needs)
112
Q

Escape

A
  • Type of socially mediated negative Rx

- Bx results in the termination of something aversive

113
Q

Escape as a Function

A
  • The Bx terminates
  • Unwanted social situation(s)/ ppl
  • New, non-preferred, or difficult tasks or activities
  • Appropriate responses ignored or delay to termination
  • Lacking appropriate communication methods
114
Q

Automatic Reinforcement

A
  • Tested by alone/ ignore condition which rules out social reinforcement
  • Type of automatic positive or negative Rx
  • Does not depend on the actions of others
  • Some sensory stimulation is produced or removed as a result of the bx
115
Q

Automatic Reinforcement as a Function

A
  • Appetitive stimulus produced (feels good)
  • Aversive stimulation is terminated
  • Problem Bx may produce/ remove sensations
116
Q

Tangible

A
  • Type of socially mediated positive Rx

- Bx results in access to “stuff”

117
Q

Tangible as a Function

A
  • Appropriate requests don’t receive the reinforcer quickly or reliably
  • Appropriate requests not in the repertoire
118
Q

Visual Analysis of Analog Functional Analysis

A
  • Line graphs used to visually compare test condition with the control condition
  • Controlling variables when the rate of Bx in the test is consistently higher than control
  • Looking for separation
119
Q

Identifying the Learned Functions of Bx:

Looking for level of bx elevated in 1 or more test conditions when compared to bx in the control

A
  • Attention
  • Escape
  • Tangible
  • Automatic Rx
  • Some combination of these
120
Q

We would say that the behavior is maintained by socially mediated negative reinforcement when the data path is elevated in the
——–condition compared to control.

121
Q

If behavior were maintained by socially mediated positive reinforcement in the form of a juice box, we would expect to see an elevated line in the———-condition compared to control.

122
Q

We would expect the data path in the _____ condition to be elevated compared to control if the behavior were maintained by automatic reinforcement

123
Q

Undifferentiated Response Patterns

A

-Lack of differences in level of responding btw conditions

124
Q

Other Possible Causes of Undifferentiated Response Patterns

A
  • Discrimination difficulties
  • Relevant variables not tested
  • Hierarchical responding
125
Q

multiple control

A

when bx is maintained by more than 1 function, Can be evidenced in a functional analysis by high rates in comparison to control in more than one condition

126
Q

Visual Analysis Summary

A
  • Compare control to test conditions
  • Condition(s) elevated relative to control indicative of Function
  • Automatic Rx potentially indicated if responding:
  • Elevated in alone conditions
  • Undifferentiated across all conditions
  • Can be more than 1 function
127
Q

Hagopian et al. (1997)

A
  • Many studies have shown visual inspection to be subjective

- Purpose: To develop structured criteria for visual inspection of multielement functional analysis data results

128
Q

Modified Visual-Inspection Criteria

A
  • Modified the structured criteria from Hagopian et al to account for Functional analyses that varies in length
  • Converted the visual-inspection criteria to to a % of data points
129
Q

Modified Visual-Inspection Criteria Primary Rule

A

*Rule: If 50% or more data points fell above upper criterion line then fell below lower criterion line, participants conclude that the condition was differentiated
