Systems Of Measurement

Question 1

Inter-Response Time (IRT)

Answer 1

A continuous system of measurement. Inter-response time (IRT) is the duration between consecutive responses in a behavior sequence.

Question 2

Duration

Answer 2

A continuous system of measurement. The time that passes from the onset (start) of the response to the offset (end) of the response

Question 3

Frequency

Answer 3

A continuous system of measurement. Counting the occurrence of each individual event

Question 4

Mike is a behavior technician working in a clinic. His client has a maladaptive behavior of spitting. This behavior has occurred consistently in sessions, so the BCBA has asked Mike to take data on the number of spitting occurrences throughout each session.

Which system of measurement will Mike likely use when taking data?

Answer 4

Frequency

Question 5

Dana is a behavior technician who holds sessions at her client’s school. Her client is working on tracing her name on paper using a pencil. Dana has reported that her client often puts her pencil down during this task and becomes distracted. The BCBA has requested that Dana take data from the time that her client stops tracing her name to the time that her client begins tracing her name.

Which system of measurement will Dana likely use when taking data?

Answer 5

Inter-Response Time

Question 6

Which system of measurement will Tiffany most likely use when taking data?

Answer 6

Duration

Question 7

Whole-Interval

Answer 7

A discontinuous system of measurement. Recording if the behavior occurs FOR THE ENTIRE INTERVAL (from beginning to end)

Question 8

Partial-Interval

Answer 8

A discontinuous system of measurement. Recording the event if it happens at ANY POINT in the ENTIRE interval.

Question 9

Momentary Time Sampling

Answer 9

A discontinuous system of measurement. Recording the event at a SPECIFIC MOMENT IN TIME BETWEEN INTERVALS.

Question 10

Continuous Measurement

Answer 10

Used to capture every possible occurrence of an event or behavior of interest.

Question 11

Discontinuous Measurement

Answer 11

Used to capture a percentage of the event or behavior of interest.
