Chapter 4

Question 1

response latency

Answer 1

fundamental measure (temporal locus-TIME)- elapsed time from the onset of a stimulus to a response

Question 2

discrete trial

Answer 2

any operant whose response rate is controlled by a given opportunity to emit the response. method for teaching a new behavior.

Question 3

trials to criterion

Answer 3

derivative measure of behavior- a special form of event recording. 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 4

types of time sampling measures

Answer 4

whole interval recording, partial interval recording, momentary time sampling

Question 5

rate/frequency

Answer 5

a ratio of count per observation time. calculated by dividing the number of responses recorded by the number of standard unites of time in which observations were conducted.

Question 6

duration

Answer 6

total extent of time in which a behavior occurs

Question 7

timing behavior

Answer 7

duration, response latency, inter-response time

Question 8

types of event recording

Answer 8

timing, time sampling, measuring by permanent product

Question 9

repeatability

Answer 9

countability- a response class can occur repeatedly through time (behavior can be counted)- fundamental measure of behavior

Question 10

magnitude

Answer 10

force or intensity with which a response is emitted - definitional measure

Question 11

3 measures of repeatability

Answer 11

count, rate/frequency, celeration

Question 12

Planned activity check (placheck)

Answer 12

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

Question 13

time sampling

Answer 13

a type of event recording- a measurement of the presence or absence of behavior within specific time intervals or specific moments in time (useful for high rate behaviors)

Question 14

event recording

Answer 14

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

Question 15

temporal locus

Answer 15

when behavior occurs in relation to other events of interest

Question 16

measurement by permanent product

Answer 16

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

Question 17

2 measures of temporal locus

Answer 17

latency, inter-response time

Question 18

celeration

Answer 18

the change in rate of responding over time

Question 19

free operant

Answer 19

emitted at any time- the number of words read during a 1 minute counting period, the number of slaps per 6 seconds, and the number of letter strokes written in 3 minutes

Question 20

celebration time period

Answer 20

a unit of time (week, month) which is plotted on a standard celebration chart

Question 21

momentary time sampling

Answer 21

procedure for measuring behavior; method in which the presence or absence of behaviors are recorded at precisely specified time intervals

Question 22

count

Answer 22

fundamental measure of behavior (repeatability)- a simple tally of the number of occurrences of a behavior

Question 23

percentage

Answer 23

a ration. examples: count (number/number); time (duration/duration; latency/latency)

Question 24

whole interval recording

Answer 24

a method of time sampling- measures behavior in brief time periods- behavior must occur the entire time of the interval. underestimates behavior.

Question 25

topography

Answer 25

definitional measures- the physical shape or form of behavior

Question 26

inter-response time (IRT)

Answer 26

a measurement of temporal locus; elapsed time between 2 successive responses; fundamental measure (temporal locus-time)

Question 27

rate

Answer 27

a ratio or count per observation time

Question 28

partial interval recording

Answer 28

a method of time sampling- the observation period is divided into a series of brief time intervals (5-10 s). Overestimates behavior- scored if the behavior occurred at any time during the interval, not how many times

Question 29

celeration trend line

Answer 29

measured as a factor by which rate multiplies or divides across the celebration time periods

Question 30

2 definitional measures of behavior

Answer 30

topography, magnitude

Question 31

artifact

Answer 31

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

Question 32

temporal extent

Answer 32

duration- amount of time- fundamental measure of behavior

Question 33

2 derivative measures of behavior

Answer 33

percentage, trials to criterion

Question 34

3 fundamental measures of behavior

Answer 34

repeatability, temporal extent (amount of time), temporal locus (when behavior occurs relative to other events)
