Unit 4 Flashcards
Unit 4 covers standard measurement and celeration.
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 a 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 bx 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 a 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? (where is the 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) x 100
(agreements/agreements + disagreements) x 100
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
dimensional quantity
a quantifiable aspect of a property
