Chapter 4 Flashcards
(23 cards)
Dimensions of measurement
- distinct features that can be measured
1. Repeatability/ count ability
2. Temporal extent
3. Temporal locus
Nonsystemic recording
- anecdotal
- yielding no quantification
Systemic recording
- recording a specific behavior
- structures format
- quantification of behavior
Repeatability/ count ability
- count
- rate/ frequency
Temporal extent
Total duration
Duration of occurrence
Count
Number of responses during an observation
Rate
Behavior / time
Locus
- Latency
- Inter-response time
- reported as mean, median, and range
Inter-response time
Time between the end of one response and the start of another response
Percentage
- most accurate with a divisor of 100 or more
- no dimensional quantity
- sets artificial limits on behavior
Trials-to-criterion
How many times it takes to achieve a goal
Topography
Physical form of a behavior
Magnitude
-force or intensity
Example: volume or distance
Event recording
Number of times behavior is observed
Time sampling
Whole interval
Partial interval
Momentary time sampling
Planned activity check
Whole-interval
- behavior occurs throughout entire time
- underestimates behavior
Partial-interval
- behaviors occurred during an interval at any time
- over estimates behavior
Momentary time sampling
Behavior occurs at the end of an interval
Planned check
Momentary time sampling with a group observation
Artifact
- Exists because it was measured
- Can be misleading
Permanent product
- measures behavior after it occurred
- effects on environment
Drift
Observer deviates or fades from the original target behavior
Duration
How long a behavior lasted
