Unit 3 Flashcards
(27 cards)
Discontinuous recording methods:
They do not capture all instances of behavior during an observation period
Interval recording
What type of measurement used?
Discontinuous measurement
Interval recording
Observation period is:
Divided into smaller time periods with established occurrence and non occurrence criteria established
Partial interval recording
Occurrence noted if behavior occurs ANY TIME during the interval
PIR stands for
Partial interval recording
Whole interval recording:
Occurrence is noted if behavior occurs for the ENTIRE interval
WIR stands for:
Whole interval recording
Momentary time sampling
Occurrence/non occurrence is observed and recorded at the end of the interval
MTS stands for
Momentary time sampling
Planned activity check
Number of group members engaging in the behavior is noted at the end of the interval.
PLACHECK stands for
Planned activity check
Discrete trial probes
Behavior sample collected during discrete trials before or after treatment is in effect
Percent:
Ratio of 2 variables multiplied by 100
Discrete categorization:
Method for classifying responses
Trials to criterion:
of opportunities required for responding to reach target performance
Permanent product:
Environmental change produced by behavior
Measurement validity:
Measure directly related to the behavior and purpose of measurement
Measurement accuracy:
Degree that measure matches actual occurrence
Measurement reliability:
Consistency of measurement
Interobserver agreement (IOA):
2 or more independent observers compare data for the same event
PIR, WIR, MTS, and PLACHECK are:
4 types of interval recording methods
PIR
High rate responding is:
Underestimated
PIR
duration of responding is:
Overestimated
WIR
duration of responding is:
Underestimated
