1

What 3 dimensional quantities does behavior have for measurement?

Repeatability
Temporal extent
Temporal Locus

2

What is repeatability?

AKA countability; Instances of a response class can occur repeatedly through time (i.e behavior can be counted.

3

What is temporal extent?

Every instances of behavior occurs during some amount of time (i.e., the duration of behavior can be measured).

4

What is temporal locus?

Every instance of behavior occurs at a certain point in time with respect to other events (i.e., when behavior occurs can be measured).

5

What are all measures based on repeatability?

Count
Rate/Frequency
Celeration

6

Define celeration.

Measures of how rates of responses change over time.

7

Free Operant

Behaviors that have discrete beginning and ending points, require minimal displacement of the organism in time and space, can be emitted at nearly any time, do not require much time for completion, and can be emitted over a wide range of response rates.

8

Measures Based on Temporal Extent

Duration

9

Measures Based On Temporal Locus

Response Latency (aka latency)
Interresponse Time

10

2 derivative measures

Percentage
Trial to Criterion

11

When do you use rate?

When behavior has a discrete beginning or end.

12

When do you not use rate?

Recording behaviors that occur only within limited or restricted conditions (e.g discrete trial data, as trials measured by opportunities)
- measuring continuous behaviors that occur for extended periods of time.

13

Formula for Celeration

count per unit of time/per unit of time

14

Use duration measurement when.

- for behaviors that occur for too long a period of time or too short a period of time.
- high rates of behaviors.
ex.: rocking, rapid jerks, on task and off task behaviors, continuous behaviors, ect.

15

Trails to Criterion

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

16

What can you use in a trials to criterion?

count, rate, duration and latency measures

17

What are two definitional measures?

Topography
Magnitude

18

3 procedures for measuring behavior:

1. Event recording
2. Timing
3. Time Sampling

19

Eventing Recording

-Methods to record the number of times a response occurs.

20

Event recording devices.

Pencil and paper, wrist counters, hand tally, digital counter, masking tape, pennies, buttons, paper clips, calculators, ect,

21

When do you use event recording?

each response has a discrete beginning and end (free operants)

22

When not to use eventing recording when:

responses occue at very high rates and/or continous behaviors (e.g on task behaviors, humming, ect.)

23

Timing is used to measure:

Duration
response latency
interresponse time (IRT)

24

Time Sampling (AKA?)

AKA: Interval Recording
- variety of methods for recording behavior during intervals or at specific moments in time.

25

What does time sampling methods gives us ________ of the actual instances of behavior.

approximation

26

3 times of Time Sampling

Whole interval Recording
Partial Interval Recording
Momentary Time Sampling

27

Whole-Interval Recording

- Watch the behavior the entire observation session .

28

What kind of behavior would you use for whole-interval recording?

continuous behavior.

29

How precise does whole-interval recording measure?

underestimates rate of behavior. The greater the interval the greater degree which the recording will underestimate actual occurrence of the behavior.

30

What does whole interval recording measure?

Yields an estimate of total duration.
