Abstract
We discuss Wittmann et al. (2007) “Effects of Psilocybin on Time Perception and Temporal Control of Behavior in Humans,” proposing that altered states of consciousness induced by pharmacological treatments and neurological disorders can reveal much about the circuitry underlying time perception in normal states of consciousness. Further research is needed to integrate these separate research domains. The brain integrates partial sensory input with internal representations to construct the elaborate story we know as time (Hammond, 2012). Our ordinary experiences reveal the complicated game the mind can play with perceived time: the day drags when we are bored, yet slips through our fingers when distracted or amused. Despite varying phenomenological experiences of time, the appropriate integration of physical time with functional behavior requires a sufficiently accurate perception structured by the conceptual framework of past, present, and future (Eagleman et al., 2005). Working memory, attention, and executive control support this integrated construction (Fuchs, 2007; Marchetti, 2014). Effects on human time perception are observed when these cognitive systems are modulated by pharmacological treatments or psychiatric disorders (Gonzalez-Maeso and Sealfon, 2009), suggesting the presence of a neurophysiological process that is intrinsic to temporal information processing (Rammsayer, 2008).

The study revealed a decreased ability to accurately produce intervals longer than 3 s and synchronize finger-tapping to auditory beats separated by more than 2 s. This suggests that effects of psilocybin on temporal processing are specific to relatively long durations, attributable to Psilocybin, Schizophrenia, and Time Perception memory, and decision-making components of the internal clock models (ICMs) (Gibbon et al, 1984; Block and Zakay, 1996; Rammsayer, 2008; Allman and Meck, 2012), rather than to more basic pacemaker/accumulator mechanisms (Wittmann et al, 2007)
