Flashcards in Chapter 4 Deck (26):
1

measurement

the process of assigning numbers and units to particular features of objects or events

2

repeatability/ countablity

instances of a response class can occur repeatedly through time (bx can be counted)

3

temporal extent

every instance of behavior occurs during some amount of time (i.e. duration)

4

temporal locus

every instance of BX occurs at a certain point in time with respect to other events (i.e. when BX occurs)

5

count

a simple tally of the number of occurrences of BX

6

rate/ frequency

number of responses per unit of time

7

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

8

discrete trials

responses are controlled by a given opportunity to emit the response

9

celeration

a measure of how rates of response change over time

10

celeration trend line

a line drawn through a series of graphed data points, visually represents the direction and degree of trend in the data

11

celeration time period

1/20 of the horizontal axis of all standard celeration charts

12

duration

the amount of time in which behavior occurs. Basic measure of temporal extent

13

response latency

the measure of time elapsed between the onset of a stimulus and the initiation of a subsequent response

14

interresponse time (IRT)

the amount of time that elapses between 2 consecutive instances of a response class

15

percentage

ratio formed by combining the same dimensional quantities
event over 100 opportunities.

16

trails to criterion

a measure of the number of response opportunities needed to acheive a predetermined level of performance

17

topography

the physical form or shape of a behavior

18

magnitude

the force or intensity with which a response is emitted

19

event recording

a wide variety of procedures for detecting and recording the number of times a behavior of interest occurs (hand tally, wrist counters)

20

time sampling

a variety of methods for observing and recording behavior during intervals or at specific moments in time

21

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

22

partial interval recording

the observer records whether the bX occurred at any time during the interval

23

measurement by permenant product

measuring BX after it has occurred by measuring the effects that the BX produced on the environment.

24

momentary time sampling

observer records whether the target behavior is occurring at the moment that each time interval ends.

25

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.

26

artifact

something that appears to exist because of the way it is examined or measured.
