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
fundamental properties of behavior
- temporal locus
- temporal extent
- repeatability
- the combination of temporal locus and temporal extent
dimensional quantities of bx
- latency
- duration
- countability
- inter-response time
- rate
- celeration (acceleration or deceleration)
temporal locus
a response occurs at a certain point in time in relation to a preceding environmental event
temporal extent
a response occupies time
latency
the amount of time between a stimulus and a response
repeatability
a response can reoccur
duration
the amount of time between the beginning and the end of the response cycle
countability (frequency)
the number of responses or the number of cycles of the response class
inter-response time (IRT)
the time between 2 successive responses; usually, the time elapsed between the end of a response cycle and the beginning of the next response cycle.
rate
the ratio of the number of responses over some period of time
celeration
changes in rate over time. usually, increases (acceleration) or decreases (deceleration) in rate over time
