Unit 4 Flashcards
Response
movement cycle
An instance or occurrence of a target behavior that
has a distinct beginning and end.
Permanent products
“A change in the environment produced by a
behavior that lasts long enough for measurement to
take place.”
Continuous (direct) response measures
“Directly measure a dimensional quantity of
behavior.”
Discontinuous (indirect) response measures
Measure a dimensionless quantity of behavior.
Types of continuous response measures
- Event recording (frequency recording)
- Latency recording
- Duration recording (per occurrence or total)
- IRT recording
Event recording (frequency recording)
A continuous (direct) response measure which measures rate.
Latency recording
A continuous (direct) response measure which measures latency.
Duration recording
A continuous (direct) response measure which measures duration.
Types of duration recording
- Duration per occurrence
* Total duration
IRT recording
A continuous (direct) response measure which measures IRT.
Types of discontinuous response measures
- Percent occurrence (and % correct)
- Trials to criterion
- Discrete categorization (coding)
- Partial interval recording
- Whole interval recording
- Momentary time sampling
- PLACHECK
Percent occurrence
A discontinuous (indirect) response measure which
measures the percentage of times a target behavior
occurs when an opportunity is presented for its
occurrence.
Trials to criterion
A discontinuous (indirect) response measure which
measures the number of consecutive opportunities to
respond, required to achieve a performance standard.
Discrete categorization (coding)
A discontinuous (indirect) response measure in which
responses are classified into discrete categories (e.g.,
severity codes, duration codes, independence codes,
etc.), and a percentage of these response categories
is obtained.
Partial interval recording
A discontinuous (indirect) response measure which measures the percentage of intervals in which a target behavior occurred at any time during an interval.
Whole interval recording
A discontinuous (indirect) response measure which measures the percentage of intervals in which a target response occurred for the total duration of an interval.
Momentary time sampling
A discontinuous (indirect) response measure which measures the percentage of intervals in which a target response was occurring at the end of an interval.
PLACHECK (Planned Activity Check)
A discontinuous (indirect) response measure which
measures the percentage of individuals that were
engaged in a target response at the end of an interval
of time.
Considerations in selecting response
measures
• Which dimensions are you interested in?
• What are the logistics involved in collecting data
(e.g., where is data going to be collected, who is
going to collect data, etc.)
Inter-observer agreement (IOA)
“The coefficient of agreement between two or more
independent observers.”
Formulas to calculate inter-observer
agreement
- (Smaller/larger) x100
* (Agreements/agreements + disagreements) x100.
How to establish adequate inter-observer
agreement
- Good response definitions
- Train observers
- Test observer agreement
- Frequent observer evaluation
Property
“A fundamental quality of a phenomenon.”
