What are the 4 dimensions of behaviour that can be measured?

Rate/Frequency
Duration
Latency
Intensity

1

Give definition and formula for calculating frequency

Number of times behaviour occurred. Converted into %

(Number of behaviours) x 100%
(Number of opportunities)

2

Give definition and formula for calculating rate

Number of times behaviour occurred during given period e.g.
Rate/min

Number of behaviours = rate/min
Number of observations

3

Give definition and formula for calculating duration

How long behaviour lasts. Calculate %

Duration x100%
Observation period

4

Give definition of latency

How long it takes for behaviour to start

5

When is using latency as a measure useful?

When reinforcing the effectiveness of activities

6

If behaviours have a clear onset and offset you can usually get a precise measure of them using (dimensions)

Duration, frequency, latency

7

When it is difficult to get precise measurements of behaviour (due to a very high occurrence or no clear onset), ____ ____ should be used

Time sampling

8

The first step in time sampling is to

Divide your observation period into intervals

9

Once observation period has been divided into intervals,

You mark whether that behaviour occurred in each interval

10

What is the calculation for time sampling? What is the data then presented as?

Number of intervals marked x 100%
Number of intervals in total

Presented as percentage of intervals

11

Name and define the 3 types of time sampling

1 whole interval - interval is marked if behaviour occurred throughout the entire interval
2 partial interval - interval marked if behaviour occurred at any point
3 momentary - behaviour marked if it occurs at end of interval (usually)

12

When should you use whole interval recording?

When goal is to increase behaviour

13

When should you use partial interval recording?

When goal is to decrease behaviour

14

When should you use momentary time sampling?

When continuous observation throughout the observation is not feasible.

15

Determining whether behaviour has occurred by measuring the outcome of behaviour is known as

Permanent product recoding

16

When should permanent product recording be used?

When observation is not possible and the behaviour has a visible, permanent outcome

17

What does real time recording refer to?

Recording the exact time of each onset/offset of behaviour, so frequency and duration are recorded at the same time

18

When is rate used instead of frequency?

When the duration of observation periods are of varying length

19

What there variables must be considered when using momentary time sampling?

1) How often a sample is taken

2) Scheduling of samples (fixed or random)

3) Length of sample (moment or few seconds)
