Audio and video recording
What are the advantages of permanent products?
Frees practitioners for other tasks, enables measurement of behaviors that occur at inconvenient or inaccessible times and places, measurement may be more accurate/complete/continuous, data collection on more participants, data collection for IOA and treatment integrity, measurement of complex behaviors and multiple response classes.
When is real time measurement need?
When moment-to-moment treatment decisions must be made such as SIB.
What are the two rules determining if a behavior can be measured by permanent product?
Each occurrence of the target behavior must produce the same permanent product, the permanent product can be produced only by the
target behavior.
What are the four questions to determine whether permanent product is appropriate?
- Is real time measurement need? 2. Can the behavior be measured by permanent product 3. Will obtaining a contrived permanent product unduly affect the behavior. 4. How much will it cost to obtain and measure the permanent product?
