Extension of the analysis of the time structure of behavioral acts

A parameter known as the K-function has previously been used to analyze the temporal structure of behavioral acts. In earlier work the study of these acts or of the joint relationship of separate acts has used a restricted list of activities whose definitions are difficult to explicate. In the present study this technique has been extended to a more extensive list of acts, each meaning of which is intuitively clear. As with the earlier work, the bootstrap method has been used to estimate the uncertainty in these measures, and the usefulness has been examined using data from studies of rats exposed to phenytoin or nitrous oxide.
