RBT Exam A. Measurement
| Question | Answer |
|---|---|
| Continuous Measurement | Recording every instance of behavior |
| frequency | count each time the behavior occurs |
| during a session the BCBA asks you to count each time the child does a behavior. What type of continuous measurement is this? | frequency |
| duration | how long the behavior occurs |
| during a session the BCBA asks you to record how long a behavior lasts from start to finish. What type of continuous measurement is this? | Duration |
| latency | the time in-between instruction/event and behavior onset |
| during a session the BCBA asks you to record how long it takes after giving an intruction for the client to begin the instructed task. What type of continuous measurement is this? | latency |
| Interresponse time (IRT) | time between two consecutive instances of a behavior |
| during a session the BCBA asks you to record the time in between when one behavior stops and then starts up again. What measurement type would this be? | Interresponse time (IRT) |
| Discontinuous measurement | recording behavior during specific intervals |
| during the session the BCBA asks you to record behavior during specific intervals | discontinuous measurement |
| partial interval | mark yes if behavior occurs at any point during the interval |
| during a session the bcba asks you to record of the behavior happens at any point during a specific time frame. what type of discontinuous measurment is this? | partial interval |
| whole interval | mark yes only if the behavior occured throughout the entire interval |
| during a session the bcba asks you to record if the behavior happens through the whole time period given. what type of discontinuous measurement is this? | whole interval |
| momentary time sampling | record if the behavior is occurring at a specific moment in time |
| during the session you set a timer for three minutes. after three minutes you look up to see if a client is doing the behavior. they are doing the behavior so you mark yes. what type of discontinuous measurement is this? | momentary time sampling |
| what is the best discontinuous measurement to use when the behaviors are brief with a clear beginning/end (hand raising/vocal requests) | frequency |
| the client engages in a behavior where they will suddenly snap their finger then pause before snapping again. what discontinuous measurement would you use to record this? | frequency |
| what is the best discontinuous measurement to use when the behaviors vary in length (tantrums, on-task behavior, transitions) | duration |
| a client engages in screaming when they do not get what they want. the screaming length varies from instructed to instance. what would be the best discontinuous measurement? | duration |
| what is the best discontinuous measurement to use when you want to capture if a behavior occured at all during a time period (aggression) | partial interval |
| a client has issues sometimes staying calm during an activity. what is the best discontinuous measurement to use when you want to see if he stayed calm during the activity | partial interval |
| what is the best discontinuous measurement to use when sustained behavior is important (engagement, on task) | whole interval |
| a client is having difficulty staying engaged during an activity. we want to measure if he can stay engaged during the full activity. what is the best discontinuous measurement? | whole interval |
