Chapter 4

Question 1

Artifact

Answer 1

An artifact or result that appears to exist because of the way it is measured but in fact does not correspond to what actually occurred

Question 2

Celeration

Answer 2

The change in rate of responding over time

Question 3

Discrete trial

Answer 3

Any operant whose response rate is controlled by a given opportunity to emit the response

Question 4

Count

Answer 4

A simple tally of the number of occurrences of a behavior

Question 5

Duration

Answer 5

The total time that behavior occurs- measured by onset of a response to its end point

Question 6

Event recording

Answer 6

Measurement procedure for obtaining a tally or count of the number of times a behavior occurs

Question 7

Free operant

Answer 7

Any operant behavior that results in minimal displacement of the participant in time and space. Can be emitted at nearly any time (opposite of discrete trial)

Question 8

Frequency

Answer 8

How often a behavior occurs

Question 9

Interresponse time (IRT)

Answer 9

The elapsed time between two successive responses (a measure of temporal locus)

Question 10

Latency

Answer 10

The elapsed time from the onset if a stimulus (a measure of temporal locus)

Question 11

Magnitude

Answer 11

The force or intensity with which a response is emitted

Question 12

Measurement

Answer 12

The process of applying quantitative labels to describe and differentiate objects and natural events

Question 13

Measurement by permanent product

Answer 13

A method of measuring behavior after it has occurred by recording the effects that the behavior produced on the environment

Question 14

Momentary time sampling

Answer 14

A measurement method in which the presence or absence of behaviors is recorded at precisely specified time intervals

Question 15

Partial-interval recording

Answer 15

A time sampling method that divides time into brief intervals and it is recorded whether the target behavior occurred at any time during the interval

Question 16

Percentage

Answer 16

A ratio of the number of responses of a certain type per total number of responses or opportunities

Question 17

Planned activity check (PLACHECK)

Answer 17

A variation of momentary time sampling in which the observer records whether each person in a group is engaged in the target behavior at specific points in time

Question 18

Rate

Answer 18

Ratio of responses per standard unit of time

Question 19

Repeatability

Answer 19

A behavior can occur repeatedly through time (one of the three dimensional qualities of behavior)

Question 20

Temporal extent

Answer 20

Refers to the fact that every instance of behavior occurs during some amount of time (one of the three dimensional qualities of behavior)

Question 21

Temporal locus

Answer 21

Every instance if behavior occurs at a certain point in time with respect to other events (one of the three dimensional qualities of behavior) (often measured with latency or IRT)

Question 22

Time sampling

Answer 22

A measurement of the presence or absence of behavior within specific time intervals

Question 23

Topography

Answer 23

The physical form or shape of a behavior

Question 24

Trials-to-criterion

Answer 24

A measure of the number of responses or practice opportunities needed for a person to achieve a pre-established level of accuracy or proficiency

Question 25

Whole-interval recording

Answer 25

A time sampling method where the observer records whether or not the target behavior occurred throughout the entire interval
