“…This idea is consistent with the proposition that dyscalculics would be more impaired when bigger numbers are involved (but see But-terworth, 2010), and also with the fact that DDs are not significantly impaired in sub-sec timings (Cappelletti et al, 2011a). Furthermore, the transition between sub-second ('automatic' or 'sensory-motor' timing, Bueti et al, 2012;Buhusi & Meck, 2005;Buonomano, 2007;Lewis & Miall, 2003;Macar et al, 2006;Naatanen et al, 2004;Wiener et al, 2010) and supra-second ('cognitive') timing mechanisms occurs at around 3 s (Gilaie-Dotan et al, 2011;Poppel, 1997), which might parallel the transition between mechanisms supporting small and larger numerosities (Agrillo et al, 2012;Buhusi & Cordes, 2011;Cordes & Brannon, 2009), although there is no consensus about this idea (see Buhusi & Cordes, 2011 for review). While a distinction between 'small' and 'large' numerosities can be dichotomised, one might also consider it on a magnitude continuum.…”

It has been suggested that the human ability to process number and time both rely on common magnitude mechanisms, yet for time this commonality has mainly been investigated in the sub-second rather than longer time ranges. Here we examined whether number processing is associated with timing in time ranges greater than a second. Specifically, we tested long duration estimation abilities in adults with a developmental impairment in numerical processing (dyscalculia), reasoning that any such timing impairment co-occurring with dyscalculia may be consistent with joint mechanisms for time estimation and number processing. Dyscalculics and age-matched controls were tested on supra-second temporal estimation (12 s), a difficulty-matched non-temporal control task, as well as mathematical abilities. Consistent with our hypothesis, dyscalculics were significantly impaired in supra-second duration estimation but not in the control task. Furthermore, supra-second timing ability positively correlated with mathematical proficiency. All participants reported that they used counting to estimate time, although no specific instructions were given with respect to counting. These results suggest that numerical processing and supra-second temporal estimation share common mechanisms. However, since this conclusion is also based on subjective observations, further work needs to be done to determine whether mathematical impairment co-occurs with supra-second time estimation impairment when counting is not involved in and is objectively controlled for during supra-second timing. We hypothesize that counting, that does not develop normally in dyscalculics, might underlie and adversely affect dyscalculics' supra-second time estimation performance, rather than an impairment of a magnitude mechanism or the internal clock pacemaker.

“…The second is a set of areas that are selectively engaged depending on the specific behavioural requirements of a task [1]. Thus, on one hand SMA and the basal ganglia of the CTBGc are activated during time production and perception tasks using both visual and auditory stimuli with various interval structures [2,3]. On the other hand, specific sensory and association areas are involved in interval timing, depending of the exact temporal paradigm [3,4].…”

Several lines of evidence suggest that motoric brain structures may form the core amodal component of a neural network supporting a wide range of timed behaviours. Here, we review recent findings which elucidate the neural computations that occur within motor regions, and in particular the supplementary motor area, in order to support precisely timed actions. Although motor activity may help us represent time, it is also clear that action both enriches and complicates the interpretation of sensory inputs. Hence, in the second half of this review, we also consider the latest findings regarding the perceptual distortions that our actions can impose upon the subjective timeline.3

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...
