Measurment Flashcards
When to use Rate
Recording free operants #DiscreteBeginingAndEnd
When to NOT use Rate (2)
- Recording Bx’s that occur only within limited/restricted conditions (Ex DTT, as trials are measured by opportunity) #OppositeFreeOperant
- Continuous Bs that occur for extended periods. #Duration
When to use Duration (3)
- Measure the amount of time of a Bx.
- Bx’s that occur for TOO LONG or TOO SHORT a period of time.
- High Rate Bx’s
Percentage Advantage
Used when you want to document the percentage of correct responses #DTT
Percantage Disadvantages (3)
- Does NOT have a dimensional value.
- Imposes lower and upper limits on the data.
- Can not use percentages to record proficiency or fluency.
When to use Trials-to-Criterion
Skills, such as shoe tying - as each pportunity can be considered a trial and trail-to-criterion data are reported as the number of trails required for the learner to tie a shoe correctl
Continuous Measurement Procedures Advantages for Bx’s that (4)
- Use for Bx with discrete beginning and ends. #FreeOperant
- Require minimum displacement of the organism in time/space
- can be emitted at any time.
- Do not require much time to complete
Continuous Measurement Procedures Disadvantages for Bx’s that (3)
- Occur at high rates or extended periods.
- Are measured using Discrete Trials.
- Are opportunity Based.
Discontinuous Measurement Procedures Advatages for Bx’s that (2)
- Occur at high rates or for longer durations of time.
2. Are measured using Discrete Trials / Percentages
Discontinuous Measurement Procedures Disadvantages for Bx’s that
- Are free operants
- it is important to obtain every occurence of that Bx.
- Requires constant attention by observers.
Event Recording Advantages ((3)
- Fairly accurate method
- Simple to implement, can do this while engaging in other activities
- Great with free operant Bx #Discrete
Event Recording Disadvantage
DO NOT USE FOR:
- Respones occuring at high rates #handflapping
- Continuous Bx (humming)
- DTT data
Time Sampling Advantage
Great for recording continuoys and/or high rate Bx
Time Sampling Disadvantage
DO NOT USE FOR: recording certain important, but fairly infrequent Bx.
Whole Interval Recording Advantage
Best for measuring Bx you want to INCREASE
Whole Interval Recording Disadvantage
Not good when looking to DECREASE Bx
Partial Interval Recording Advantages (2)
- Easy to measure multiple Bx’s concurrently
2. Best for measuring Bx’s you want to DECREASE
Partial Interval Recording Disadvantages (2)
- Not good when looking to INCREASE Bxs.
2. Have to observe for Bx through the whole interval
Momentary Time Sampling Advantage
DO NOT have to continuously measure throughout the whole interval
Momentary Time Sampling Disadvantages (2)
- Much of the Bx of interest is missed or uncounted
2. To avoid, keep intervals short and observe the target Bx frequently
