“…Some suggest this duration compression is related to repetition suppression, which assumes repeated signals reduce neural responses (Grill-Spector, Henson, & Martin, 2006;Henson & Rugg, 2003). This also is in line with the predictive coding, which suggests that the brain do little when the incoming stimulus matches the internal expectation but passes prediction errors for further processing when the incoming signal deviates from the prediction (Eagleman & Pariyadath, 2009;Friston, 2005;Rao & Ballard, 1999;Shi & Burr, 2016). However, a recent study by Matthews (2015) reported that the repetition compression of subjective duration is reduced and even reversed when repetition trials become more frequent.…”

“…One proposal for the repetition compression is coding efficiency under the framework of predictive coding (Eagleman & Pariyadath, 2009;Matthews et al, 2014), which argues repetition suppression depends on the differences between the predicted and the actual signals. The predictive coding framework (Friston, 2005, Rao & Ballard, 1999 assumes that bottom-up signals are only passed on to the next stage when the information deviates from the top-down predictions.…”

Our prior experience heavily influences our subjective time. One of such phenomena is repetition compression, that is, repeated stimuli are perceived shorter than novel stimuli. However, most of the studies on repetition compression used identical stimuli, leaving the question whether similar repetition effects could take place in phonological and semantic level repetition. We used Chinese characters to manipulate different levels of repetition in a duration discrimination task. We replicated earlier findings that repetition of visual identical characters shortened the apparent duration and found the repetition compression was spatially independent. Phonological repetition also caused the duration compression though the effect was weaker than the visual repetition. However, we observed no duration compression during the semantic repetition. The results suggest that repetition compression is mediated by visual and phonological representation of a stimulus in an early stage in processing hierarchy. We explained our findings according to the framework of predictive coding.

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.

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.
