Answer 5

Measuring the time at when the behavior occurs (point in time

Answer 6

Time between onset of a stimulus and initiation of a response

Question 7

Answer 7

Amount of time that elapses between 2 consecutive instances of a response class

Question 8

2 Derivative Measures

Answer 8

1. Percentage

2. Trials-to-Criterion

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

Question 10

2 Definitional Measures

Answer 10

1. Topography

2. Magnitude

Question 11

Topography

Answer 11

Form or shape of the response, not the function

Question 12

Magnitude

Answer 12

Force, intensity, severity of the behavior

Question 13

Continuous Measurement Procedures

Answer 13

Measurement conducted in a manner such that ALL instanced of the response class are detected during the observation period (event recording)

Question 14

Discontinuous Measurement Procedures

Answer 14

Measurement conducted in a manner such that some instances of the response class of interest may not be detected (time sampling methods)

3 Procedures for Measuring Behavior ETT

Answer 15

Event Recording
Timing
Time Sampling

Timing

Answer 16

Used to measure duration, response latency, and interresponse time

3 Forms of Time Sampling (WPM)

Answer 18

Whole Interval Recording
Partial Interval Recording
Momentary Time Sampling

Question 19

Planned Activity Check

Answer 19

A group version of momentary time sampling where the teacher count the number of students engaging in the behavior at the end of the interval

Question 20

Ethics Warning: Measurement

Answer 20

Select a measurement method that provides the most ethical and valid description of the target behavior

Question 21

Ethics Warning: Planning Observation

Answer 21

Truly capture what the target behavior really looks like when you conduct data collection

Question 22

Scheduling Observation and Recording Periods

Answer 22

Think about the time of day, week, weather conditions, task assignments, etc.

Question 23

3 Indicators of Trustworthy Measurement (VAR)

Answer 23

Validity
Accuracy
Reliability

Question 24

Vailidity

Answer 24

Directly measuring socially significant behaviors and ensuring that the data are representative of the behavior occurrence under conditions during relevant times.

Question 25

Threats to Measurement Validity

Answer 25

Indirect Measurements, Measuring the wrong dimension of the target behavior, Measurement artifacts

Question 26

Measurement Artifcacts

Answer 26

Discontinuous measurement Poorly scheduled measurement periods Insensitive/limited measurement scales

Question 27

Accuracy

Answer 27

The extent to which the observed value matched the true value of an event

Question 28

Measuring True Values

Answer 28

Process must be different than the measurement procedure for the observed values.

Question 29

Reliability

Answer 29

the extent to which a measurement procedure uyiled the same value when brought into repeated contact with the same state of nature.

Question 30

Threats to Measurement Reliability

Answer 30

Human error Poorly designed measurement Inadequate observer training Expectations about what the data should look like

Question 31

Observer Drift

Answer 31

hen an observer unknowingly alters the way they measure a behavior

Question 32

Measurement Bias

Answer 32

Nonrandom measurement error that is likely to be in one direction.

Question 33

Observer Reactivity

Answer 33

Measurement error resulting from an observer's knowledge that others are evaluating the data that she reports
