Descriptive Assessment
method of obtaining information about the function a behavior that serves & guides the design of the intervention
- direct observation
- naturally occurring condition
Ways to Collect Descriptive Data
ABC Narrative Recording (data collected when behavior occurs & is open ended-notes)
ABC Continuous Recording (records behavior & presents antecedent/consequence-selected conditions based on interviews)
Ecological Assessments (gather information about the person & various environments where they live and work)
Ways to Measure Behavior
- Count
- Frequency
- Duration
- Latency
- Interresponse Time
- Celeration
- Trials-to-Criterion
- Percentage
- Magnitude
- Topography
Graphs Used
Line Graph-comparing pts. reveals the presence & extent of changes in level, trend, and/or variability w/in & across conditions
Bar Graph (Histogram)- doesn’t have distinct data points, contains discrete sets of data & group/average performance
Cumulative Record- primary use in EAB (Skinner), # of responses in each obs. period is added to the total # of responses from all prev. sessions, steeper slope=higher response rate, & compare slopes to analyze conditional effectiveness
Standard Celeration Chart-Ogden Lindsley, standardized way to analyze how frequency changes over time, semilogarithmic chart w/6- x10 cycles, scaling of the x/y axis
Scatter plot- shows relative distribution of individual measures in a data set w/respect to variables depicted by the x/y axis, data pts=unconnected, doesn’t show FR-just correlations/relationships
Procedures for Measurement
Event recording (Count) Timing (Duration) Time Sampling -whole -partial -momentary -PLACHECK (group behavior) -Permanent Product
Functional Analysis
Analysis of the function of a behavior wherein antecedent-consequences representing those in a natural environment are arranged w/in an experiment design so that their separate effects on the problem behavior can be observed & measured
- Contingent attention (Positive R+)
- Contingent Escape (Negative R+)
- Alone (Automatic R+)
- Control (Play)
Visual Analysis of Alt. Tx Design
- Look for distance b/w the paths
* Undifferentiated when results are inconclusive
Functional Analysis (Pros/Cons)
Advantages:
- clear demo of the variables that relate to the occurrence of a prob. beh.
- effective R+ based on interventions can be developed w/less reliance on punishers
Limitations:
- process may temporarily strengthen/increase prob. beh.
- deliberate arrangements that promote the ben. may seem counterintuitive to persons outside ABA
- Some beh. won’t be amenable for an FA
- Contrived vs. Natural setting (other variables)
- Time, Effort * Prof. Expertise Required
Designs
AB Reversal (ABAB) Withdrawal (ABA) Multiple BSL Alt. Tx. Changing Criterion
Visual Analysis (w/in conditions)
- # of data points
- variability
- level (value on the x-axis)
- trend (direction of path)
Visual Analysis (across conditions)
- use variability/stability, level, trend
- OVERLAP
- mean/median lines can help compare levels b/w conditions
- trend (change in direction/slope)
Task Analysis
Involves breaking a complex skill into smaller, teachable unit, where product=sequentially ordered steps/task
Constructing a TA
- How to Determine sequence of events
- Behavioral components are developed after observing a competent individual perform the desired sequence
- Consult w/ experts or persons skilled at performing task
- Perform task oneself
Assessing Mastery
- Single Opportunity (perform each behavior in TA in correct sequence)
- Multiple Opportunity Method (evaluates level of mastery across all behaviors-each ind. task)
Ways to Teach A TA
- Forward Chaining
- Backward Chaining
- Total Task Chaining
