Flashcards in Measuring Dimensions Deck (20):

0

## 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
