• Question 11:

  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.
  C. overestimate of the occurrence of the behavior.

  A. does not specify an interaction between an organism and its environment.
  B. can occur under only one, very specific environmental condition.
  C. is a hypothetical construct and cannot therefore meet the criteria for an occurrence of behavior.

  D. there is the possibility that the effect of one intervention will influence the effect of another.
