“…Evidence suggests that during mind wandering, one's attention is coupled to task-independent thoughts and concomitantly dissociated from perceptual input, resulting in an attenuation of sensory processing (perceptual decoupling; (Barron, Riby, Greer, & Smallwood, 2011;Smallwood, Beach, Schooler, & Handy, 2008). The magnitude of processing resources directed to a timed interval is related to its perceived duration such that greater, or lesser, allocation of resources is associated with temporal dilation, or contraction, respectively (Berry, Li, Lin, & Lustig, 2014;Buhusi & Meck, 2009). The association between perceived duration and resource allocation suggests that perceptual decoupling during mind wandering states will lead to distortions in interval timing.…”

Our perception of time varies considerably from moment to moment, but how this variability relates to endogenous fluctuations in attentional states has been neglected. Here, we tested the hypothesis that perceptual decoupling during spontaneous mind wandering episodes distorts interval timing. In two studies with different visual subsecond interval timing paradigms, participants judged their attentional state on a trial-by-trial basis. Mind wandering states were characterized by underestimation of temporal intervals and a decline in temporal discrimination. Further analyses suggested that temporal contraction during mind wandering, but not the decline in temporal discrimination, could be attributed in part to attentional lapses. By contrast, we did not find any robust evidence that metacognition pertaining to interval timing was altered during mind wandering states. These results highlight the role of transient fluctuations in attentional states in intraindividual variability in time perception and have implications for the perceptual consequences, behavioral markers, and costs and benefits, of mind wandering.

“…The involvement of attention mechanisms is a fundamental issue in contemporary research on timing and time perception (Brown & Boltz, 2002;Buhusi & Meck, 2009;Burle & Casini, 2001;Hemmes, Brown, & Kladopoulos, 2004). Although the variability of estimates is sometimes argued to depend on attention, the role of attention is most commonly used for explaining the perceived duration of involving, for instance, a series of partially overlapping visual displays marking intervals of different lengths that had to be timed for eventual reproduction.…”

Suppose someone had to prepare a review article on visual perception, instead of time perception. This individual would probably ask for a series of reviews, with at least one-and probably several-dedicated to color, distance, shape, and motion perception, and maybe to other aspects of visual perception. It would be very difficult to complete the same exercise for time perception since the categories of temporal experiences are not as clearly defined. However, for a reader to understand the scope of a text on time perception, it is essential to develop a representation of what the main research avenues or categories are. The present text should help the reader to grasp the scope of recent literature related to psychological time and time perception.After a brief overview of the various perspectives on what could be meant by psychological time, the review will propose to identify of series of key concepts and empirical findings that should delineate the field of time perception and timing, and will discuss some models of time perception. The article also provides a review of the main recent findings in the field in which a neuroscientific approach to timing is adopted. In this section, the roles of the cerebellum, of the cerebral cortices, and of the basal ganglia in the timing processes are emphasized. Time Perception Beyond the Focus of the Present ReviewThere is a wide range of research on psychological time and temporal processing, mainly because of the ubiquity of time in behavior and the relevance of a temporal perspective in regard to living organisms and events. There is a vast literature in social psychology as to how behavior is shaped by time (see Perret-Clermont, 2005, or Strathman & Joireman, 2005, which includes topics such as time management, time perspective, and time orientation, or the relative value of past and future (Caruso, Gilbert, & Wilson, 2008;Zimbardo & Boyd, 1999). Even within the scope of experimental psychology, some studies have emphasized how the temporal structure of events determines our perception of the world (see the second part of Helfrich, 2003).Some authors who are interested in consciousness have adopted a phenomenological perspective on time (see the first part of Buccheri, Saniga, & Stuckey, 2003). Indeed, time and consciousness have become more closely linked recently with the development of a new area of research on the concept of chronesthesia (awareness of subjective time; Tulving, 2002), as opposed to noetic consciousness (awareness of the world) or autonoetic consciousness (awareness of self in time). Interestingly, there is now evidence that even animals can anticipate the future (Roberts, 2008).There are many psychological time studies related in various ways to memory processes (Block & Zakay, 2008). One research avenue deals with the chronology of events in our lives, particularly the memory of the order of occurrence of these events (Damasio, 2002;Friedman, 1993 The aim of the present review article is to guide the reader through portions of the human time per...

“…In internal clock models, similar to a stop watch, a pacemaker produces a series of pulses and the number of pulses recorded over a given time span represents subjective duration (Church 1984;Treisman et al 1990;Zakay & Block 1997). Testing a variant of these model types with rats and using a specific task (the peak interval procedure), Buhusi & Meck (2009) show the importance of allocating attention to time as opposed to the situation when subjects are distracted from time. The authors do note that the cognitive time sharing hypothesis finding empirical support in their experiments can be applied to any neuronal model of time perception.…”

Time research has been a neglected topic in the cognitive neurosciences of the last decades: how do humans perceive time? How and where in the brain is time processed? This introductory paper provides an overview of the empirical and theoretical papers on the psychological and neural basis of time perception collected in this theme issue. Contributors from the fields of cognitive psychology, psychiatry, neurology and neuroanatomy tackle this complex question with a variety of techniques ranging from psychophysical and behavioural experiments to pharmacological interventions and functional neuroimaging. Several (and some new) models of how and where in the brain time is processed are presented in this unique collection of recent research that covers experienced time intervals from milliseconds to minutes. We hope this volume to be conducive in developing a better understanding of the sense of time as part of complex set of brain-body factors that include cognitive, emotional and body states.
