Chapter 4

Question 1

measurement

Answer 1

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

Question 2

repeatability/ countablity

Answer 2

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

Question 3

temporal extent

Answer 3

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

Question 4

temporal locus

Answer 4

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

Question 5

count

Answer 5

a simple tally of the number of occurrences of BX

Question 6

rate/ frequency

Answer 6

number of responses per unit of time

Question 7

free operant

Answer 7

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

Question 8

discrete trials

Answer 8

responses are controlled by a given opportunity to emit the response

Question 9

celeration

Answer 9

a measure of how rates of response change over time

Question 10

celeration trend line

Answer 10

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

Question 11

celeration time period

Answer 11

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

Question 12

duration

Answer 12

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

Question 13

response latency

Answer 13

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

Question 14

interresponse time (IRT)

Answer 14

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

Question 15

percentage

Answer 15

ratio formed by combining the same dimensional quantities

event over 100 opportunities.

Question 16

trails to criterion

Answer 16

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

Question 17

topography

Answer 17

the physical form or shape of a behavior

Question 18

magnitude

Answer 18

the force or intensity with which a response is emitted

Question 19

event recording

Answer 19

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

Question 20

time sampling

Answer 20

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

Question 21

whole interval recording

Answer 21

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

Question 22

partial interval recording

Answer 22

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

Question 23

measurement by permenant product

Answer 23

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

Question 24

momentary time sampling

Answer 24

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

Question 25

planned activity check (PLACHECK)

Answer 25

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.

Question 26

artifact

Answer 26

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