“…In both tasks however, patients were characterized by flatter gradients than controls, indicating less accurate and especially overall more variable timing capacities. Using a similar comparative method, Wilquin et al (2010) and Ameller et al (2011) also reported preserved perceptual detection of irregularities in otherwise regular sequences for interval shorter than 500ms, even if once more patients revealed overall more errors in their decision making.…”

“…Another patient reported: "he would shoot gun fires towards his watch in order to kill time, which he considered as his worst enemy" (Minkowski, 1933, p. 13). More recently, a French psychologist transcribed examples of time distortions in young patients with Ultra High Risk of developing schizophrenia and with first-episode psychosis (15-25 years of age) for her PhD work (Wilquin, 2010). In her work, she reported, for example, a young patient who said to have found himself in front of closed gates at his high school on three different consecutive days, in the middle of the night.…”

“…Yet an additional possibility is that the overestimations and underproductions are a consequence of systematic memory distortions . Indeed, recent studies have observed significant correlations between the performance on time perception tasks and that found in neuropsychological outcomes typically affected in schizophrenia (e.g., Lee et al, 2009;Wilquin et al, 2010).…”

“…Still using a synchronization-continuation finger-tapping task, we wanted to go further by assessing the effects of task difficulty and attention demands for motor timing during motor sequencing. For this reason, we manipulated the complexity of the rhythm and/or the complexity of the motor task to perform motor sequences in synchrony with an external metronome (Wilquin et al, 2010). The participants' task was to squeeze a force transducer in its centre in beat with a metronome for a 12-s period, and then to continue producing the same rhythm in a continuation phase for another 12-s period (Figure 6.1left).…”

Examinations of aspects of temporal processing in clinical populations may inform not only typical psychological functioning -but may also elucidate the psychological consequences of any pathophysiological differences in temporal processing. This line of scientific enquiry may improve understanding, and potential remediation, of the psychological condition.Humans are equipped with the remarkable ability to estimate event duration, recall past events, remember to execute future tasks, and perceive a multisensory and temporally unified world. This ability enables us (and other animals) to anticipate, learn, and adapt to temporal regularities and dynamics in the social and non-social environment. Moreover, the perception of time, typically (although not always) reveals hallmarks shared by other forms of perception (e.g., Weber's law). Thus, even though our subjective experience of time might be quite different from the actual, physical duration of an event, temporal experience remains an important and necessary part of our everyday living and ultimately forms the fabric of our thoughts and behaviors.Distortions in aspects of temporal processing from the range of milliseconds to seconds, to conceptual notions of a timeline for time (past, present, future) have been separately reported for a variety of psychological disorders. Aside from adages such as "a watched pot never boils" and "time flies when you're having fun," the experience of time distortions by the healthy individual may require oneself to imagine a world in which aspects of our temporal experiences are "off." For example, you have some sense of how long you've been reading this. Now imagine that this was suddenly uncertain for you (minutes, hours?). You would most likely feel anxious and aroused and would likely engage in different patterns of behavior and decision-making. Go a step further and imagine that you experience events that are disorganized in terms of order, duration, and sensory integration. How would that feel? There is no mental disorder of timing; and it is fair to say that deficits in timing are not characterizing deficits of any mental disorder. But it is also fair to say that the way in which aspects of temporal perception and sensitivity influence our psychology is profound, and there are many interesting findings implicating aspects of timing to the neurological, behavioral, and cognitive profiles characteristic of a number of mental disorders (many of which are described in this book!).Perception, cognition, and action are tightly intertwined with events unfolding in time and, thus, many processes such as working memory, attention, decision making etc. are linked to timing, and implicated in successful interval timing models. Disturbance of one or more of these related processes could Argiro Vatakis and Melissa Allman -978-90-04-23069-9 Downloaded from Brill.com10/23/2020 09:31:29PM via free accessxi preface image's quality and presentation), and Mary Kostaki, who worked on the design of the cover for this book (and showed patience t...
