Chapter 4 Flashcards
measurement
the process of assigning numbers and units to particular features of objects or events
repeatability/ countablity
instances of a response class can occur repeatedly through time (bx can be counted)
temporal extent
every instance of behavior occurs during some amount of time (i.e. duration)
temporal locus
every instance of BX occurs at a certain point in time with respect to other events (i.e. when BX occurs)
count
a simple tally of the number of occurrences of BX
rate/ frequency
number of responses per unit of time
free operant
behaviors that have discrete beginning and ending points, require minimal displacement in time and space, can be emitted at nearly any time, do not require much for completion, can be emitted over a wide range of response rates
discrete trials
responses are controlled by a given opportunity to emit the response
celeration
a measure of how rates of response change over time
celeration trend line
a line drawn through a series of graphed data points, visually represents the direction and degree of trend in the data
celeration time period
1/20 of the horizontal axis of all standard celeration charts
duration
the amount of time in which behavior occurs. Basic measure of temporal extent
response latency
the measure of time elapsed between the onset of a stimulus and the initiation of a subsequent response
interresponse time (IRT)
the amount of time that elapses between 2 consecutive instances of a response class
percentage
ratio formed by combining the same dimensional quantities
event over 100 opportunities.
trails to criterion
a measure of the number of response opportunities needed to acheive a predetermined level of performance
topography
the physical form or shape of a behavior
magnitude
the force or intensity with which a response is emitted
event recording
a wide variety of procedures for detecting and recording the number of times a behavior of interest occurs (hand tally, wrist counters)
time sampling
a variety of methods for observing and recording behavior during intervals or at specific moments in time
whole interval recording
the observation period is divided into a series of brief time intervals. at the end of each interval the observer records whether or not the behavior occurred throughout the interval
partial interval recording
the observer records whether the bX occurred at any time during the interval
measurement by permenant product
measuring BX after it has occurred by measuring the effects that the BX produced on the environment.
momentary time sampling
observer records whether the target behavior is occurring at the moment that each time interval ends.
planned activity check (PLACHECK)
uses head counts to measure group BX.
-counts the number of students engaged in the target activity and records the tally with the total number of students in the group.
artifact
something that appears to exist because of the way it is examined or measured.
