1

3 dimensional quantities

1.Repeatability
2.Temporal Extent
3.Temporal Locus

2

Repeatability

Count
Rate aka Frequency
Celeration- Count per unit of time/time

3

Temporal Extent

Duration
"High rate behaviors"

4

Temporal Locus

Locus=Point of time

Response Latency (Latency)
IRT

5

Derivative Measures

1. Percentage
2. Trials to Criterion

6

2 definitional measures

1.Topography
2.Magnitude

7

Continuous Measures

Measurement conducted in a manner that all instances of the response class interests are detected during the observation period

8

Continuous Measures Advantages

Free Operant
Discrete beginning and ending
Emitted at any time

9

Continuous Measures Disadvantages

Not useful for behaviors that
are high rates
measured as discrete trials
Opportunity Based

10

Discontinuous Measures

Some instances of the response class may NOT be detected

11

Discontinuous Measures Advantages

High Rates
Long durations of time
Measured as discrete trials
Measured as percentages

12

3 procedures for measuring behavior

Event Recording
Timing
Time Sampling

13

Event Recording

# of times a response class occurs

Hand tallies, counters, buttons and calculators

14

Timing

Duration
Response Latency
Irt
Stop Watch

15

Time Sampling

Variety of methods for recording behavior during interval or at specific moments in time

16

3 forms of time sampling

Whole Interval Recording
Partial Interval Recording
Momentary Time Sampling

17

Whole Interval Recording

Underestimates the rate of a behavior
Through the entire interval

18

Partial Interval Recording

Over estimates the rate of behavior
Half the interval

19

Momentarily Time Sampling

Over or Under estimates the rate of behavior
End of the interval

20

Planned Activity Check

Groups
Variation of Momentarily Time Sampling
Groups of students

21

Permanent Product

Measuring behavior after it has occurred by measuring the effects the behavior produced on the environment

22

3 trustworthy measurements

Validity
Accuracy
Reliability

23

Validity

Directly measuring socially significant target behaviors.

Measuring dimension of the target behavior relevant to the question or concern about the behavior

24

Threats measurement validity

Indirect Measurements
Measuring the wrong dimension of the target bx
measurement artifacts

25

3 causes of measurement artifacts

1. Discontinuous Measurements
2. Poor Scheduled Measurement Periods
3. Insensitive or limiting measurement scales

26

Accuracy

Observed Value
True Value
Requires special or precautions that all possible sources of error have been removed

27

Reliability

Measurement procedures yields the same value when brought into repeated contact with the same state of nature

Same results repeatedly

28

Observer Drift

Alter the way they measure a behavior

29

Measurement Bias

Errors in measurement likely to be in one direction

30

Naive Observers

Minimize measurement bias. Trained observer who is unaware of the study purpose
