“…Moreover, this difference was more prominent at frontal and central electrode sites between 500 and 1500 ms after the offset of S1. The spatial distribution of these slow waves was similar to that reported in other ERP/EEG studies of duration information processing (e.g., Monfort, et al, 2000;Monfort & Pouthas, 2003;Schubotz & Friederici, 1997) and the polarity and the magnitude of the amplitude difference were comparable to those reported by Monfort and Pouthas (2003) in their Gap trial modification of the standard S1-S2 paradigm.…”

“…In this paradigm, S1 and S2 durations of either the same or different magnitude, are presented successively with an interleaved retention delay (e.g., Schubotz & Friederici, 1997;Hälbig et al, 1998;Monfort & Pouthas, 2003;Schubotz & Friederici, 1997;). Therefore, SW amplitude differences during the retention ISSN 1303 5150 www.neuroquantology.com interval for different duration S1 stimuli would suggest differential memory demands.…”

“…More directly relevant to the approach taken here is an experiment by Monfort and Pouthas (2003). These authors explored the relationship between slow waves and temporal processing with a hybrid S1-S2 paradigm in which the S2 presentation was split into two parts on some trials (Gap trials).…”

“…For example, in Monfort and Pouthas (2003) participants had to keep the representations of the S1 and initial part of the S2 distinct in order to complete the task successfully. Therefore, it is unclear whether the SW difference was due to keeping two durations separate in memory across the delay interval, to the duration magnitude, or to some combination of the two factors.…”

Whether duration magnitude modulates the cognitive resources required to represent that duration in memory is a fundamental question about the cognitive architecture of interval timing. The amplitudes of the Event-Related Potential (ERP) Slow Waves (SWs) elicited when participants maintain representations of different durations (e.g., 1500 versus 3000 ms) in memory may provide an answer to this question because increased positive SWs have been associated with increased working memory demands in studies of verbal and spatial memory. Here, participants judged whether a probe stimulus (S2) was the same duration as the preceding sample stimulus (S1). SWs recorded during a 2 s delay interval between S1 and S2 presentation were significantly more positive in the 3000 ms condition than in the 1500 ms condition, particularly at frontal-central electrode locations. This result suggests that the magnitude of the duration to be remembered influences the cognitive resources required to represent that duration in working memory.

“…This finding is compatible with the idea that the CNV amplitude reflects the accumulation of time information, probably pulses if one refers to the pacemaker-counter device described earlier, with more counted pulses resulting in larger CNV amplitude. In brief, additional findings based on CNV indicate that frontal regions play a critical role in the accumulation of temporal information (Pfeuty, Ragot, & Pouthas, 2003b), during the building of an interval memory trace (Pfeuty, Ragot, & Pouthas, 2003a), and during the retention of temporal information (Monfort & Pouthas, 2003; see also .…”

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...

We investigated how two different reading tasks, namely reading to memorize [Read & Memorize (RM)] and reading to decide whether a text was relevant to a given topic [Read & Decide (RD)], modulated both eye movements (EM) and brain activity. To this end, we set up an ecological paradigm using the eye fixation-related potentials (EFRP) technique, in which participants freely moved their eyes to process short paragraphs, while their electroencephalography (EEG) activity was recorded in synchronization with their EM. A general linear model was used to estimate at best EFRP, taking account of the overlap between adjacent potentials, and more precisely with the potential elicited at text onset, as well as saccadic potentials. Our results showed that EM patterns were top-down modulated by different task demands. More interestingly, in both tasks, we observed slow-wave potentials that gradually increased across the first eye fixations. These slow waves were larger in the RD task than in the RM task, specifically over the left hemisphere. These results suggest that the decision-making process during reading in the RD task engendered a greater memory load in working memory than that generated in a classic reading task. The significance of these findings is discussed in the light of recent theories and models of working memory processing.
