Question 1

partial-interval recording

Answer 1

a data measurement system in which a positive occurrence is recorded if the behavior occurs at any time during the interval

Question 2

percentage

Answer 2

a data conversion method for restricted event data

allows for varying number of opportunities to respond across the measurement period

Question 3

stereotypic behaviors

Answer 3

a repetitive behavior, such as hand-flapping, rocking, twirling objects, or monotone humming, that appears to be for the purpose of self-stimulation

Question 4

replacement behaviors

Answer 4

a desired behavior that is designed to be part of an intervention plan as a substitute for an unacceptable behavior

is established through teaching, prompting, and reinforcement

Question 5

latency recording

Answer 5

a data system used to measure the time elapsed between when a stimulus is given and when the response for that stimulus begins

Question 6

interval recording

Answer 6

data collection system in which the presence or absence of a target behavior is documented during brief, regular intervals

Question 7

restricted events

Answer 7

a behavior that occurs in response to a specific stimulus

Question 8

permanent products

Answer 8

a concrete, tangible result or outcome of a behavior

Question 9

discrete behaviors

Answer 9

behaviors that have a clearly observable beginning and end

Question 10

unrestricted events

Answer 10

a behavior that can occur at any time rather than only in the presence of a particular stimulus

Question 11

whole-interval recording

Answer 11

a type of interval recording in which only an occurrence of the targeted behavior that lasts throughout the interval is counted as an occurrence

Question 12

operational definition

Answer 12

an unambiguous, objective definition of a targeted behavior

often includes examples and non examples of the behavior

Question 13

trends

Answer 13

three consecutive data points in the same direction

Question 14

duration recording

Answer 14

a system for measuring the length of time for which a behavior is exhibited

this method is appropriate for behaviors that have a clearly identifiable beginning and end and that occur over a long period

Question 15

scale break

Answer 15

two short slash marks across the y-axis of a graph that indicate the omission of increments on the scale

Question 16

baseline data

Answer 16

the amount of a behavior that occurs before an intervention is implemented

usually gathered for 3-5 observation periods before an intervention is implemented

Question 17

rate

Answer 17

a data conversion method for unrestricted event data

used when the measurement period varies or when the goal is to increase or decrease the number of times a behavior occurs during a particular period

Question 18

fidelity

Answer 18

the extent to which an intervention is implemented correctly, as originally designed and researched

Question 19

event/frequency recording

Answer 19

a data collection system that is used for counting instances of discrete behavior

Question 20

data points

Answer 20

symbols indicating data from each observation session

plotted on the intersection of the vertical and horizontal lines

Question 21

time sampling

Answer 21

a data measurement system in which the data collector indicated whether or not the targeted behavior is occurring at the end of each interval
