Measurements Flashcards
Three fundamental properties of measurable dimensions of behavior
a) repeatability or accountability
b) temporal extent
c) temporal locus
what is the timeline measurement is conducted?
Before, during, and after treatment
Temporal extent means
Duration
Measures based on repeatability
Count, Frequency, Rate
Numbers of responses emitted during an observation period is reported?
as frequency
Rate of correct and incorrect measures are helpful in?
skill development
Measures based on temporal locus
Latency, Interresponse time
Response latency
The measurement how quickly or slow a behavior occurs after an opportunity bega
Interresponse time
Amount of time that elapses between two consecutive instances of a response class; (transitions)
Percentage
A ratio formed by combining the same dimensional qualities
Proportion of correct to incorrect
Trial-to-criterion
Measure of the number of response opportunities needed to achieve a predetermined level of performance
Topography
The physical form or shape of a behavior
anything involving the senses
Magnitude
The force or intensity with which a response is emitted
Devices used for event recording
wrist counters, digital counters, masking tape, paper clips, etc
Recording timing
procedures to measure duration, response latency, and interresponse time
List A, B, C how((a) and why(b,c) we use Partial interval recorded.
a) at end of interval record if behavior occurred at any time during the interval
b) allows for multiple occurrences scored as one
c) allows for recording of multiple behaviors
Sampling parital interval recording is recorded?
as percentage of intervals when behavior occurred
Count
number of responses emitted during an observation period
Rate/Frequency
ratio of count per observation period
Guidelines for using rate
a) takes the complexity of response into account
b) a useful measure for free operants
c) not appropriate for responses within discrete trials
d) not appropriate for continuous behavior over an extended period
Celeration
measures of the change in rate of responding per unit of time
Duration
the amount of time a behavior occurs
Event recording
procedures for detecting and recording the number of times a behavior is observed
Devices used for timing duration, response latency, and interresponse
computer systems, stopwatch, wall clocks, tape recorder
Time sampling whole interval recording
a) used to measure continuous behavior
b) brief intervals (5-15 seconds)
c) at end of interval - record if behavior occurred throughout
d) risk of underestimation (something you want to increase)
e) reported as a percentage of intervals when behavior occurred
Momentary time sampling
recoding whether or not the behavior occurred right at the moment the interval elapsed
Permanent product recording
you measure some physical product that the behavior produced
Procedures for measuring behavior
- Event recording
- Timing
