title: Whenever next: hierarchical timing of perception and action.
abstract: The target article focuses on the predictive coding of "what" and "where" something happened and the "where" and "what" response to make. We extend that scope by addressing the "when" aspect of perception and action. Successful interaction with the environment requires predictions of everything from millisecond-accurate motor timing to far future events. The hierarchical framework seems appropriate for timing.
