Time perception is a field of study within psychology, cognitive linguistics and neuroscience that refers to the subjective experience, or sense, of time, which is measured by someones own perception of the duration of the indefinite and unfolding of events. The perceived time interval between two successive events is referred to as perceived duration. Though directly experiencing or understanding another persons perception of time is not possible, such a perception can be objectively studied and inferred through a number of scientific experiments. Time perception is a construction of the sapient brain, but one that is manipulable and distortable under certain circumstances. These temporal illusions help to expose the underlying neural mechanisms of time perception. Pioneering work, emphasizing species-specific differences, was conducted by Karl Ernst von Baer. Experimental work began under the influence of the psycho-physical notions of Gustav Theodor Fechner with studies of the relationship ...
Our perception of time constrains our experience of the world and exerts a pivotal influence over a myriad array of cognitive and motor functions. There is emerging evidence that the perceived duration of subsecond intervals is driven by sensory-specific neural activity in human and nonhuman animals, but the mechanisms underlying individual differences in time perception remain elusive. We tested the hypothesis that elevated visual cortex GABA impairs the coding of particular visual stimuli, resulting in a dampening of visual processing and concomitant positive time-order error (relative underestimation) in the perceived duration of subsecond visual intervals. Participants completed psychophysical tasks measuring visual interval discrimination and temporal reproduction and we measured in vivo resting state GABA in visual cortex using magnetic resonance spectroscopy. Time-order error selectively correlated with GABA concentrations in visual cortex, with elevated GABA associated with a rightward
Slow time perception can be learned Ralf Buckley Arstila (2012) reviewed competing hypotheses for the perception of slow time. Perception of time is fundamental to human understanding, and the neurophysiological mechanisms involved are heavily studied (Eagleman, 2008; Wittmann, 2011, 2013; Phillips, 2013). Abnormal perceptions such as slow time provide an analytical tool. Here I put forward additional evidence from high-risk, high-skill outdoor recreation. Reported experiences

Duration discrimination within the seconds-to-minutes range, known as interval timing, involves the interaction of cortico-striatal circuits via dopaminergic-glutamatergic pathways. Besides interval timing, most (if not all) organisms exhibit circadian rhythms in physiological, metabolic and behavioral functions with periods close to 24 h. We have previously reported that both circadian disruption and desynchronization impaired interval timing in mice. In this work we studied the involvement of dopamine (DA) signaling in the interaction between circadian and interval timing. We report that daily injections of levodopa improved timing performance in the peak-interval procedure in C57BL/6 mice with circadian disruptions, suggesting that a daily increase of DA is necessary for an accurate performance in the timing task. Moreover, striatal DA levels measured by reverse-phase high-pressure liquid chromatography indicated a daily rhythm under light/dark conditions. This daily variation was affected by ...
Non-motor symptoms in Parkinsons Disease (PD) predate motor symptoms and substantially decrease quality of life; however, detection, monitoring, and treatments are unavailable for many of these symptoms. Temporal perception abnormalities in PD are generally attributed to altered Basal Ganglia (BG) function. Present studies are confounded by motor control facilitating movements that are integrated into protocols assessing temporal perception. There is uncertainty regarding the BGs influence on timing processes of different time scales and how PD therapies affect this perception. In this study, PD patients using Levodopa (n = 25), Deep Brain Stimulation (DBS; n = 6), de novo patients (n = 6), and healthy controls (n = 17) completed a visual temporal perception task in seconds and sub-section timing scales using a computer-generated graphical tool. For all patient groups, there were no impairments seen at the smaller tested magnitudes (using sub-second timing). However, all PD groups displayed
The duration of incidents in dynamic human-machine system represent crucial information for system analysis and the regulation of task-performance. With rising task-demands people tend to be less reliable in time-estimations and cause errors in their interaction with a complex system. A model of time perception was developed in the course of this project, which posits that working memory mechanisms distort time perception under certain circumstances. This approach was integrated into a cognitive architecture. With such an integrated approach of human time perception it is possible to predict temporal human errors in the context of complex dynamical systems. In early phases of system development a system could be evaluated and blueprints could be favoured or sources of error could be detected or prevented. In order to verify the developed quantitative model, predictions for variations of a counting task were generated. These predictions were compared with date of a series of three experiments. In ...
One of the most influential interval timing paradigms assumes a pacemaker-accumulator clock (pacemaker-counter) and was introduced by Treisman [15]. According to Treisman [15], the interval timing mechanism that links internal clock to external behaviour also requires some kind of store of reference times and some comparison mechanism for time judgement. The model was rediscovered two decades later and became the scalar expectancy theory (SET) [5,16]. SET also assumes that interval timing emerges from the interaction of three abstract blocks: clock, accumulator (working or short-term memory) and comparator. The clock stage is a Poisson process whose pulses are accumulated in the working memory until the occurrence of an important event, such as reinforcement. At the time of the reinforcement, the number of clock pulses accumulated is transferred from the working (short-term) memory and stored in a reference (or long-term) memory. According to the SET, a response is produced by computing the ...
Time Discrimination Task Time discrimination task, modified from Smith et al. (2002) presents the green circle on the left first, followed by the red circle on the right. The subject is asked to press the key to indicate the circle with longer duration. The standard stimuli and comparison last for 1000ms, and 1350ms, respectively. The two circles are randomly presented. If the answer is correct, the comparison duration decreases in 15ms; if the answer is wrong, the comparison duration increases in 15ms. The task continued either until the subject had made six reversals, or until 20 trials, whichever occurs first.. Time Reproduction Task The time reproduction task is modified from Barkley et al. (1997). First, the green circle is present on the central for seconds with five durations: 2, 5, 10, 12, and 17seconds. Subject is asked to press key to create the same temporal duration as green circle. Two trials are given at each of these five durations with random presentation.. The raw time ...
The scalar timing or scalar expectancy theory (SET) is a model of the processes that govern behavior controlled by time. The model posits an internal clock, and particular memory and decision processes. SET is one of the most important models of animal timing behavior. John Gibbon originally proposed SET to explain the temporally controlled behavior of non-human subjects. He initially used the model to account for a pattern of behavior seen in animals that are being reinforced at fixed-intervals, for example every 2 minutes. An animal that is well trained on such a fixed-interval schedule pauses after each reinforcement and then suddenly starts responding about two-thirds of the way through the new interval. (See operant conditioning) The model explains how the animals behavior is controlled by time in this manner. Gibbon and others later elaborated the model and applied it to a variety of other timing phenomena. SET assumes that the animal has a clock, a working memory, a reference memory, and ...

Summary: Human time judgments are affected by various psychological factors. Our study tested whether factors known to influence time perception would also affect the tempo at which a familiar tune sounds right(hereafter referred to as subjective tempo). Two experiments tested the effects of 1) physiological arousal and 2) age on subjective tempo for common tunes such as Happy Birthday. It was hypothesized that 1) arousal induced via exercise would increase subjective tempo relative to a control task (anagrams)and that 2) subjective tempo would decrease with age. All participants completed a perception task, in which the tempi of tunes heard aloud were adjusted in real time, and an imagery task, in which the speed of a click track was adjusted to match the tempi of imagined tunes. Subjective tempo was positively associated with increased arousal, but was not related to age. Results are discussed in relation to pacemaker-accumulator models of timing and theories of cognitive slowing.. ...
Timing is essential to human behaviour, but the neural mechanisms underlying time perception are still unclear. New findings from a brain-imaging study by Coull et al. show that activity in a network of motor-related areas varies parametrically with attention to time. Given that a system in which timing is important (but not the primary function) is recruited when temporal judgements are required, we should perhaps reassess the notion of a dedicated timing system in the brain.

5 healthy subjects and 9 patients with hospital diagnoses of schizophrenia were studied by means of repeated measurements of time estimation (production method) during a 1- to 2-yr period. The healthy subjects exhibited moderate variability in their time estimations and tended to over- or under-estimate somewhat. Both over- and under-estimation were also found among patients, but the patients were often more variable in their estimations and in some cases deviated more from the correct estimation than the healthy subjects. Two patients were decided under-estimators. They were both young, subchronic schizophrenics. Chronic schizophrenic patients tended to over-estimate time, but the amount of over-estimation had no noticeable correlation to the degree of clinical disturbance. Two patients gradually changed from under- to over-estimation during the observation period. One patient was evidently misdiagnosed. He suffered from a bipolar affective disorder, and his time estimations seemed to depend on his
Abstract: The model [N. Todd, ``A theory of the principal monaural pathway. I. Pitch and time perception, J. Acoust. Soc. Am. (these proceedings)] proposes to account for auditory streaming by a cross-correlation mechanism modeled as an array of cortical columns. A column contains excilatory and inhibitory interneurons and pyramidal cells which receive input from both the thalamus and from neighboring columns. For columns with coherent thalamic inputs, the outputs of the pyramids sum across frequency because local interneurons compute a correlation between the AM transform of the inputs of the local and remote columns, and selectively gate the input to the pyramidal cell. (1) Grouping by frequency proximity---for columns separated by less than a critical band, thalamic inputs are unresolved. (2) Grouping by temporal proximity---at repetition rates below the mean of the AM distribution, AM fundamentals are less well represented; at higher repetition rates the AM harmonics are more separated. ...
It has been suggested previously that at least some levels of the temporal organization for speech production are characterized by proportional timing. The proportional timing model maintains that the duration of temporal intervals within a sequence would remain proportionally invariant across changes in overall duration of the sequence. In order to test this hypothesis for the acoustic level of speech production, 18 women produced three trials of the utterance " Buy Bobby a poppy" at each of three speaking rates (i.e., slow, normal, fast). Acoustically derived temporal intervals were paired to form ratios reflecting either syllablelevel or phrase-level relative timing. Findings indicated that ratios of temporal intervals at both the syllable-level and phrase-level did not remain invariant across speaking rates. Rather, statistically significant changes in the relative duration of both types of intervals were observed as a function of overall rate of production. For most of the obtained ratios, ...

[more ▼]. Objective: Autonoetic awareness enables to mentally relive personal events in memory to be aware of ones own experiences across subjective time and so to have a feeling of individuality and self-direction. It is intimately associated with our awareness of ourselves as persons with a past and a future. Autonoetic awareness thereof contributes to construction of our identity by the recovery of past events, particularly specific events, and the imagination of future events. According to Danions theoretical model (2001), autonoetic awareness impairment is at the heart of schizophrenia. This deficit should depend on defective associations between separate aspects of the events during the recall and therefore, it is associated with a reduction in accessing specific information ...

Visual binding is the process by which the brain groups the elements belonging to one object, whilst segregating them from other scene elements. A computationally parsimonious mechanism of visual binding is the binding-by-synchrony (BBS) hypothesis. According to this hypothesis, detectors that respond to elements of a single object fire in synchrony, while detectors that respond to elements of different objects do not. Current psychophysical and physiological evidence are inconclusive about the role of BBS in the visual integration process. Here we provide psychophysical and computational evidence suggesting that the visual system implements a mechanism that synchronizes response onsets to object parts and attenuates or cancels their latency differences. In three experiments, observers had to judge the synchrony of two flickering Gabor patches embedded in a static Gabor contour, passing through fixation. We found that a smooth contour, as compared to a jagged one, impedes judgments of temporal synchrony

0040]FIG. 6 is a flowchart of transmission timing adjustment processing according to the present embodiment. Reception timing detection unit 12 detects the reception timing of a received downlink radio frame (S100). Reception signal demodulation unit 14 demodulates the received signal (S101). If transmission timing information is included in the control signal, reception signal demodulation unit 14 sends the above transmission timing information to transmission timing adjustment unit 15. Transmission timing adjustment unit 15 decides the presence or absence of transmission timing information at each predetermined decision interval (S102). If the transmission timing information is sent, transmission timing adjustment unit 15 adjusts the transmission timing to a specified value included in the transmission timing information (S103). If the transmission timing information is not sent, transmission timing adjustment unit 15 decides whether the handover processing is in progress, based on the ...
It is well established that the PFC is crucially involved in time-interval discrimination in humans (Mangels et al., 1998; Koch et al., 2003; Jones et al., 2004) and animals (Glickstein et al., 1964; Rosenkilde and Divac, 1976; Dietrich et al., 1997; Dietrich and Allen, 1998; Onoe et al., 2001; Kim et al., 2009b). However, the exact role of the PFC in interval timing behavior has not been clear. It has been suggested that estimation of a time interval (clock), its storage and retrieval (memory), and comparison with a newly estimated time interval (comparison/decision) are three basic processes for all internal clock models (Wearden, 1999). The PFC might be in charge of one or more of these steps. Alternatively, the intact PFC might be needed for interval-timing behavior because of its general executive functions (Mangels et al., 1998; Tregellas et al., 2006; Livesey et al., 2007; such as attentional control). If PFC neurons are found to convey information about time intervals only after their ...
This study investigated the ability of individuals with Parkinsons disease (PD) to synthesize temporal information across the senses, namely audition and vision. Auditory signals (A) are perceived as lasting longer than visual signals (V) when they are compared together, since attention is captured and sustained more easily than for visual information. We used the audiovisual illusion to probe for disturbances in brain networks that govern the resolution of time in two intersensory conditions that putatively differ in their attention demands. PD patients and controls judged the relative duration of successively presented pairs of unimodal (AA, VV) and crossmodal (VA, AV) signals whilst undergoing fMRI. There were four main findings. First, underestimation of time was exaggerated in PD when timing depended on controlled attention (AV), whereas subtle deficits were found when audition dominated and attention was more easily sustained (VA). Second, group differences in regional activation were observed
The speeding-up of neural processing associated with attended events (i.e., the prior-entry effect) has long been proposed as a viable mechanism by which attention can prioritize our perception and action. In the brain, this has been thought to be regulated through a sensory gating mechanism, increasing the amplitudes of early evoked potentials while leaving their latencies unaffected. However, the majority of previous research has emphasized speeded responding and has failed to emphasize fine temporal discrimination, thereby potentially lacking the sensitivity to reveal putative modulations in the timing of neural processing. In the present study, we used a cross-modal temporal order judgment task while shifting attention between the visual and tactile modalities to investigate the mechanisms underlying selective attention electrophysiologically. Our results indicate that attention can indeed speed up neural processes during visual perception, thereby providing the first electrophysiological support
Recent evidence suggests that interval timing (the judgment of durations lasting from approximately 500 ms. to a few minutes) is closely coupled to the action control system. We used surface electromyography (EMG) and motion capture technology to explore the emergence of this coupling in 4-, 6-, and 8-month-olds. We engaged infants in an active and socially relevant arm-raising task with 7 cycles and response period. In one condition cycles were slow (every 4 seconds) in another they were fast (every 2 seconds). In the slow condition, we found evidence of time locked sub-threshold EMG activity even in the absence of any observed overt motor responses at all 3 ages. This study shows that EMGs can be a more sensitive measure of interval timing in early development than overt behavior.. ...

For personal reasons I am so glad you are not an MD but a Doctor of Philosophy. Yes, your point is valid, but though what you said touches on this, what I said really meant, my fault, was: How can a nontemporal "God" act temporally? Of course this has problems with my presuppositions about how "God" as an "object" or "genus" exists which, operating on Lloyd P. Gersons analysis of what Plotinus "One" is - or better, what it is NOT but is necessary in the so-called "Great Chain of Being" for it to even begin temporally or have an intellectual starting one, all concepts dependent on human contingency and finite, predicates that apply whether "God" exists or not. Gerson would say that "God" or the "One" is beyond or above existence which, though it sounds at first glance like babble, is the only human way to conceive of the beginning of existence and time, that is "being alive" in two (2) different senses. The "One" would not need to state as First principle "existence exists" as a human being ...

In the present study, we investigated the relation between cognitive performance and heart rate variability as a function of fitness level. We measured the effect of three cognitive tasks (the psychomotor vigilance task, a temporal orienting task, and a duration discrimination task) on the heart rate variability of two groups of participants: a high-fit group and a low-fit group. Two major novel findings emerged from this study. First, the lowest values of heart rate variability were found during performance of the duration discrimination task, compared to the other two tasks. Second, the results showed a decrement in heart rate variability as a function of the time on task, although only in the low-fit group. Moreover, the high-fit group showed overall faster reaction times than the low-fit group in the psychomotor vigilance task, while there were not significant differences in performance between the two groups of participants in the other two cognitive tasks. In sum, our results highlighted the
In temporal information processing, both the cerebellum and the basal ganglia play essential roles. In particular, for interval timing learning, the cerebellum exhibits temporally localized activity around the onset of the unconditioned stimulus, whereas the basal ganglia represents the passage of time by their ramping-up activity from the onset of the conditioned stimulus to that of the unconditioned stimulus. We present a unified computational model of the cerebellum and the basal ganglia for the interval timing learning task. We report that our model reproduces the localized activity in the cerebellum and the gradual increase of the activity in the basal ganglia. These results suggest that the cerebellum and the basal ganglia play different roles in temporal information processing.. Date: 09/11/2018 ...
Back of the Book This book will make meditation into a discipline. Everyone eats foods, but if you are knowledgeable about the kinds of foods and eat properly, then benefits increase. Everyone exercises, but if you use better methods and are disciplined, then it becomes many, many times more effective. Similarly, everyone meditates, but when you study this book and adopt meditation as a discipline, then the benefits will be enhanced many times over. In the real world of clocks and objective time, we live minute. The past is a memory and the future is unknown. In the mental world of subjective time, we generally live in the past. The present is overcome by the past and the subjective future is false knowledge. This book is about the mental world of subjective time. Meditation aims at removing an alienation from reality caused by subjective time. Once subjective/mental/self based time ends, the false knowledge of the world created by the self/mind ends.

Scientists have learned a great deal about how THC acts in the brain to produce its many effects. When someone smokes marijuana, THC rapidly passes from the lungs into the bloodstream, which carries the chemical to the brain and other organs throughout the body. THC acts upon specific sites in the brain, called cannabinoid receptors, kicking off a series of cellular reactions that ultimately lead to the "high" that users experience when they smoke marijuana. Some brain areas have many cannabinoid receptors; others have few or none. The highest density of cannabinoid receptors are found in parts of the brain that influence pleasure, memory, thoughts, concentration, sensory and time perception, and coordinated movement.[1] Not surprisingly, marijuana intoxication can cause distorted perceptions, impaired coordination, difficulty in thinking and problem solving, and problems with learning and memory. Research has shown that marijuanas adverse impact on learning and memory can last for days or ...

Michael Harper for redOrbit.com - Your Universe Online A new study published this week in the journal PLoS ONE explains that active and healthy people are more likely to have better attention spans than those with sedentary lifestyles.. Researchers from the University of Granada carried out the study and found that physical activity, such as running or playing sports, can improve the functions of the central nervous system (CNS) and autonomic nervous system (ANS). In addition to a longer attention span, active people were also found to have better cognitive abilities than their less active peers. To reach this conclusion, the University of Granada researchers compared cognitive performance by testing the sustained attention, time oriented attention and time perception of their subjects.. A group of 28 young males comprised the study´s subjects, many of them University of Granada students. These students, aged 17 to 23, showed a "low level of physical aptitude" and represented the less active ...
Mental time travel refers to the ability to recall episodic past and imagine future events. The present study aimed to investigate cultural differences in mental time travel between Chinese and Australian university students. A total of 231 students (108 Chinese & 123 Australians) participated in the study. Their mental time travel abilities were measured by the Sentence Completion for Events from the Past Test (SCEPT) and the Sentence Completion for Events in the Future Test (SCEFT). Results showed that there were no cultural differences in the number of specific events generated for the past or future. Significant differences between the Chinese and Australian participants were found mainly in the emotional valence and content of the events generated. Both Chinese and Australian participants generated more specific positive events compared to negative events when thinking about the future and Chinese participants were more positive about their past than Australian participants when recalled specific
What does time travel have to do with all this? Like most developments in science and technology, time travel is an attempt to tip over the scales of humanity, to overcome these limits that keeps man chained to the laws of nature regarding his life and how he travels through it. Additionally, if time travel were possible, man would overcome the struggle of not knowing certain things like the backdoors of history or what he is bound to be in the future. He can even save himself from a certain direction of fate if only he knows where hes heading; he can live a life that spans a million years with just one visit to the past, and another to the future. He can immortalize himself, leaving a mark all through the universe, that man the unlimited has done what he thought he cannot ...
Recent studies have associated increasing temporal expectations with synchronization of higher frequency oscillations and suppression of lower frequencies. In this experiment, we explore a proposal that low-frequency oscillations provide a mechanism for regulating temporal expectations. We used a speeded Go/No-go task and manipulated temporal expectations by changing the probability of target presentation after certain intervals. Across two conditions, the temporal conditional probability of target events differed substantially at the first of three possible intervals. We found that reactions times differed significantly at this first interval across conditions, decreasing with higher temporal expectations. Interestingly, the power of theta activity (4-8 Hz), distributed over central midline sites, also differed significantly across conditions at this first interval. Furthermore, we found a transient coupling between theta phase and beta power after the first interval in the condition with high temporal
TIME TRAVEL"~ Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person, typically using a hypothetical device known as a time machine,in the form of a vehicle or of a portal connecting distant points in spacetime,either to an earlier time or to a later time, without the need for the time-traveling body to experience the intervening period in the usual sense. Time travel is a widely-recognized concept in philosophy and fiction. It was popularized by H. G. Wells 1895 novel The Time Machine, which moved the concept of time travel into the public imagination. However, it is uncertain if time travel to the past is physically possible. Forward time travel, outside the usual sense of the perception of time, is possible according to special relativity and general relativity, although making one body advance or delay more than a few milliseconds compared to another body is not feasible with current ...
The aim of this research was to study the relationship between perceptual judgments about space and time. If spatial and temporal judgments were dissociable, they should be modulated selectively by attention. We compared the effect of the attentional set upon fine-grained spatial versus temporal discrimination of visual perception in two experiments. Using identical sensory stimulation, we measured perceptual judgments on either the size of a small spatial gap or the duration of a brief temporal gap. The attentional set was manipulated by cuing the task that was most likely to be performed. In one experiment, a neutral cue was also used, to measure relative benefits and costs of spatial and temporal task sets. If the attentional set could be directed selectively to spatial and temporal task-relevant dimensions, performance on both spatial and temporal acuity tasks should be specifically modulated by task cuing. The results showed that the attentional set enhanced the speed and accuracy of perceptual
