The rehabilitation therapist wants to determine if the sensory integration sessions are helping to reduce Ed's hand-slapping. What is the BEST method for recording momentary time-sampling data?
A. Fifteen-minute observation periods are divided into 3-minute intervals. Staff then record whether or not hand-slapping is occurring at the end of each 3-minute interval.
B. Twenty-minute observation periods are divided into 10-minute intervals. Staff then record whether or not hand-slapping is occurring during each 10-minute interval.
C. Thirty-minute observation periods are divided into 2-minute intervals. Staff then record whether or not hand- slapping occurs at any moment during each 2-minute interval.
D. One-hour observation periods are divided into 10-minute intervals. Staff then record whether or not hand- slapping occurs at all during each 10-minute interval.

Observation sessions should be scheduled so that the representativeness of the data can be maximized. Considering behaviors occurring in a school setting, which of the following options is consistent with this recommendation?
A. Behaviors are given letter-codes that represent the complete topographical definition of the behaviors, e.g., "on-task academic behavior" is represented by "O" on the recording sheet.
B. Observations should be made only when the behavior is likely to occur most frequently during a day, for instance, during a particular academic class.
C. Recordings of behavior during the whole school day may be needed initially to assess the representativeness of samples within the day.
D. Representativeness can be assured by scheduling observations in sessions of 60 minutes or more in the morning and afternoon school schedule.

Susan recorded data on a student's fidgeting behavior in the following way: She divided a 10- minute recording period into 10-second intervals and recorded in each interval a "+" if the target behavior occurred at least once. The percentage of intervals of target behavior occurrence was about 45%. The data resulting are most likely to be an
A. accurate measure of inter-response times.
B. inaccurate measure of inter-response times.
C. overestimate of the occurrence of the behavior.
D. underestimate of the occurrence of the behavior.
