Measurment

Question 1

When to use Rate

Answer 1

Recording free operants #DiscreteBeginingAndEnd

Question 2

When to NOT use Rate (2)

Answer 2

1. Recording Bx’s that occur only within limited/restricted conditions (Ex DTT, as trials are measured by opportunity) #OppositeFreeOperant
2. Continuous Bs that occur for extended periods. #Duration

Question 3

When to use Duration (3)

Answer 3

1. Measure the amount of time of a Bx.
2. Bx’s that occur for TOO LONG or TOO SHORT a period of time.
3. High Rate Bx’s

Question 4

Percentage Advantage

Answer 4

Used when you want to document the percentage of correct responses #DTT

Question 5

Percantage Disadvantages (3)

Answer 5

1. Does NOT have a dimensional value.
2. Imposes lower and upper limits on the data.
3. Can not use percentages to record proficiency or fluency.

Question 6

When to use Trials-to-Criterion

Answer 6

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

Question 7

Continuous Measurement Procedures Advantages for Bx’s that (4)

Answer 7

1. Use for Bx with discrete beginning and ends. #FreeOperant
2. Require minimum displacement of the organism in time/space
3. can be emitted at any time.
4. Do not require much time to complete

Question 8

Continuous Measurement Procedures Disadvantages for Bx’s that (3)

Answer 8

1. Occur at high rates or extended periods.
2. Are measured using Discrete Trials.
3. Are opportunity Based.

Question 9

Discontinuous Measurement Procedures Advatages for Bx’s that (2)

Answer 9

1. Occur at high rates or for longer durations of time.

2. Are measured using Discrete Trials / Percentages

Question 10

Discontinuous Measurement Procedures Disadvantages for Bx’s that

Answer 10

1. Are free operants
2. it is important to obtain every occurence of that Bx.
3. Requires constant attention by observers.

Question 11

Event Recording Advantages ((3)

Answer 11

1. Fairly accurate method
2. Simple to implement, can do this while engaging in other activities
3. Great with free operant Bx #Discrete

Question 12

Event Recording Disadvantage

Answer 12

DO NOT USE FOR:

• Respones occuring at high rates #handflapping
• Continuous Bx (humming)
• DTT data

Question 13

Time Sampling Advantage

Answer 13

Great for recording continuoys and/or high rate Bx

Question 14

Time Sampling Disadvantage

Answer 14

DO NOT USE FOR: recording certain important, but fairly infrequent Bx.

Question 15

Whole Interval Recording Advantage

Answer 15

Best for measuring Bx you want to INCREASE

Question 16

Whole Interval Recording Disadvantage

Answer 16

Not good when looking to DECREASE Bx

Question 17

Partial Interval Recording Advantages (2)

Answer 17

1. Easy to measure multiple Bx’s concurrently

2. Best for measuring Bx’s you want to DECREASE

Question 18

Partial Interval Recording Disadvantages (2)

Answer 18

1. Not good when looking to INCREASE Bxs.

2. Have to observe for Bx through the whole interval

Question 19

Momentary Time Sampling Advantage

Answer 19

DO NOT have to continuously measure throughout the whole interval

Question 20

Momentary Time Sampling Disadvantages (2)

Answer 20

1. Much of the Bx of interest is missed or uncounted

2. To avoid, keep intervals short and observe the target Bx frequently
