|
Target Behavior
|
Any DEFINED, observable, and measurable bx that is the focus of ANALYSIS and INTERVENTION
|
|
|
Do we measure and change bx?
|
No -- we measure and change Dimensional Quantities of bx
(i.e. latency, duration, etc.) |
|
|
Latency
|
amount of time between stimulus and response
|
|
|
Duration
|
amount of time the response occupies
|
|
|
Frequency s/be
Countability |
Number of responses --
Responses tend to reoccur |
|
|
Response class
|
multiple responses --
has its own dimensional quantities (i.e. IRT, celeration, etc) |
|
|
IRT
|
Inter-response time =
time between two responses |
|
|
Rate
|
same as frequency =
number of responses over some period of time |
|
|
Celeration
|
Change in bx over time --
Rates/time = graphed |
|
|
IRTs Increase
IRTs Decrease |
Increase = Rate decrease .....
Decrease = Rate Increase |
|
|
Is this an example of target behavior? Social Skills
|
No -- too broad (8)
|
|
|
Is this an example of target behavior? On-task
|
No -- too broad (12)
|
|
|
IRT, Rate, and Celeration all share which fundamental properties?
|
Repeatability and Temporal locus
|
|
|
The student completes 30 math problems correctly.
Ex. of which dimensional quantity? |
frequency / countability
|
|
|
Data
|
QUANTITATIVE results of deliberate, planned, and usually controlled OBSERVATION
singular = DATUM |
|
|
Characteristics of a Good Response Definition
|
-Objective
-Clear -Complete |
|
|
Characteristics of a Good Response Definition
- Objective |
refers only to the observable
|
|
|
Characteristics of a Good Response Definition
-Clear |
readable, unambigous, allows replication (technological)
|
|
|
Characteristics of a Good Response Definition
- Complete |
delinates boundaries of what is and what is not an instance of bx
|
|
|
Topographical Response Definitions
|
What it looks like,
Intensity or magnitude, Functional response definitions include the topography |
|
|
Functional Response Definitions
|
Specific information identifying target bx, antecedents, and consequences
|
|
|
Continuous (Direct) Measures
|
Directly measure a Dimensional Quantity i.e. event recording = frequency, latency recording, duration recording, etc.)
|
|
|
Discontinuous (Indirect) Measures
|
Measure a dimensionless quantity, (i.e. percent)
i.e. trials to criterion, discrete categorization, partial interval, whole interval, momentary time sampling, placheck |
|
|
Restricted operants
|
Antecedent required
i.e. to answer a question, you need a question |
|
|
Estimating IRTs
|
recording interval / count
|
|
|
trials to criterion
|
number of consecutive opportunities to respond required to achieve a performance standard
|
|
|
discrete categorization (coding)
|
classifying responses into discrete categories
i.e. severity codes, duration codes, independence codes |
|
|
Partial interval recording
|
discontinuous response measure
recording session broken into short intervals of time (10-20 sec) response is recorded as occurring if it happens at any time during the interval est. of occurrence use to record behavior to decrease |
|
|
whole interval recording
|
session broken into short intervals, response is recorded as occurring if happens during the entire (whole) interval
use to record bx to increase |
|
|
momentary time sampling
|
record as occurring (+) only if it occurs at the end of the interval, precise moment
|
|
|
placheck
|
for a group of individuals
observed at the end of the interval count how many are engaging in target behavior |
|
|
How the results of discontinuous / indirect / time sampling are reported
|
As percents
|
|
|
Advantages and disadvantages of using continuous measuring procedures
|
more valid
less practical IOA more difficult to acheive |
|
|
Interobserver agreement
|
reliability = consistency of measurement
in ABA achieved through agreement between 2 or more independent observers 80% minimum |
|
|
methods of determining IOA
|
continuous = smaller / larger x 100
discontinuous = agreements / total x 100 |
