Mechanisms of Timing: An integrative theoretical approach

Accurate timing allows individuals to perform functions central to societal demands, such as scheduling, responding to warning signals, and planning. Since timing impacts various functions, it is considered a cognitive primitive; however, research often examines each modality individually, providing a disjointed, myopic view of the mechanisms of timing. This study extends prior work by integrating and explaining the relationship between two commonly examined timing modalities, neurophysiological and behavioral, and relating these lower-level processes of timing to upper-level, social-cognitive timing abilities (SCTA). The hypothesis is that those with better neurophysiological timing (NPT) are associated with better SCTA and this relationship is mediated by accurate behavioral timing. Participants (N=36) were screened for psychopathologies associated with timing deficits and underwent EEG recordings of neurophysiology using mismatch negativity, two behavioral timing tasks, and three SCTA tasks. The direction of the relationship between NPT, behavioral accuracy and the latent variable SCTA was tested with two mediation models. Model 1 tested behavioral accuracy as a mediator of the c-path, NPT underlying SCTA. Model 2 tested the reverse c-path and had better model fit. Model 2 demonstrated a significant relationship of SCTA predicting NPT. Results suggested that those with high behavioral accuracy also demonstrate increases in SCTA and NPT. SCTA plays a key role in determining NPT abilities; therefore, tactics to increase time accuracy should target this realm. The hierarchical relationship between each level of timing should be explored to determine if timing is a singular, yet multifaceted domain, or if timing is composed of separate entities.
