Which observation method provides a measure of group behavior by recording whether each member of a group is engaged in the target behavior at specific points in time?

Which observation method provides a measure of group behavior by recording whether each member of a group is engaged in the target behavior at specific points in time?

• A. Planned Ignoring
• B. Partial Interval Recording
• C. Phylogeny
• D. PlacCHECK

Answer: (D)

PlacCHECK involves taking snapshots of the group at predetermined moments and recording for each member whether they are engaged in the target behavior. This yields a clear measure of group behavior by showing who is doing the behavior at those specific check times, allowing you to compute the proportion of the group engaged at each observation moment. This method is specifically designed to capture group engagement across time by scanning every member at each check, making it a direct measure of how the whole group is behaving at those moments. In contrast, partial interval recording looks for whether the behavior occurred at any point within an interval (which can overestimate group activity and doesn’t provide per-person snapshots at exact times), planned ignoring is a behavior-management tactic rather than an observation method, and phylogeny is unrelated to observing behavior.
