Overview of some of the key philosophical problems encountered making sense of the notion of "subjective time", with a focus on the experience of duration. The paper unpacks some of the assumptions behind an intuitive picture of duration experience I call the "simple flow" view, highlighting the availability of alternative models. It then considers a number of obstacles to providing an account of the individuation of subjective features of duration experience.

We report two experiments in which participants had to judge the time of occurrence of a stimulus relative to a clock. The experiments were based on the control condition used by Libet, Gleason, Wright, and Pearl [Libet, B., Gleason, C. A., Wright, E. W., & Pearl, D. K. . Time of conscious intention to act in relation to onset of cerebral activities : The unconscious initiation of a freely voluntary act. Brain 106, 623–642] to correct for any bias (...) in the estimation of the time at which an endogenous event, the conscious intention to perform a movement, occurred. Participants’ responses were affected systematically by the sensory modality of the stimulus and by the speed of the clock. Such findings demonstrate the variability in judging the time at which an exogenous event occurs and, by extension, suggest that such variability may also apply to the judging the time of occurrence of endogenous events. The reliability of participants’ estimations of when they formed the conscious intention to perform a movement in Libet et al.’s study is therefore questionable. (shrink)

Some recent physiological data indicate that the “subjective timing” of experiences can be “automatically referred backwards in time” to represent a sequence of events even though the earlier portions of associated neurophysiological activity are themselves insufficient to elicit the experience of any sensation. The challenge, then, is to explain how subjects can experience what they do in the reported ways when, if one looked just at certain neurophysiological activity, it would seem that perhaps subjects should report their sensations (...) differently. The phenomenon has seemed sufficiently remarkable to the neurobiologist John Eccles to count as evidence for mind-body dualism. This dualistic interpretation has resulted in a spirited attack by P. S. Churchland on both the physiological research and the dualistic interpretation. Her attack resulted in an equally spirited defense of the research by the primary investigator, B. Libet, where he reaffirmed his more guarded interpretation that “the temporal discrepancy creates relative difficulties for identity theory, but that these are not insurmountable”. In turn, Churchland has defended her criticism of Libet's research so that, for her, Libet's hypothesis remains “infirm and unconfirmed”. (shrink)

This article explores contemporary approaches to the understanding and interpretation of the formation of inclusive society. The focus is on the investigation of the everyday experiences of individuals who face various limitations in their living conditions such as limited opportunities, special needs, and disabilities. The paper highlights the importance of considering the unique aspects of subjective time when systematically analyzing the functional characteristics and existential mechanisms of an inclusive society, which constitutes the living environment for people with disabilities. (...) It points out that the temporal intentionality of a mentally challenged individual manifests in a unique form of ordering, synchronization, and existence within various phenomena and events within the individual's mental imagery and inner experiences. The authors emphasize the necessity to differentiate two primary stages in an individual's perception and understanding of their actual existence—the evaluation stage and the stage of identifying prospects. The study shows how intentional temporality inherently transforms into individual time, revealing the peculiarities of internal experiences and the unique aspects of an individual's mental imagery. These are integral steps in the formation of a system of social events that are marked within the individual consciousness. The novelty of this study lies in the examination of intentionality within the framework of a disabled person's subjective time, a characteristic that is fundamentally individual yet resonates with the collective daily consciousness of disabled individuals within an inclusive micro-society.

Saccadic chronostasis refers to the subjective temporal lengthening of the first visual stimulus perceived after an eye movement. It has been quantified using a duration discrimination task. Most models of human duration discrimination hypothesise an internal clock. These models could explain chronostasis as a transient increase in internal clock speed due to arousal following a saccade, leading to temporal overestimation. Two experiments are described which addressed this hypothesis by parametrically varying the duration of the stimuli that are being judged. (...) Changes in internal clock speed predict chronostasis effects proportional to stimulus duration. No evidence for proportionality was found. Two further experiments assessed the appropriateness of the control conditions employed. Results indicated that the chronostasis effect is constant across a wide range of stimulus durations and does not reflect the pattern of visual stimulation experienced during a saccade, suggesting that arousal is not critical. Instead, alternative processes, such as one affecting the onset of timing are implicated. Further research is required to select between these alternatives. (shrink)

How a human observer perceives duration depends on the amount of events taking place during the timed interval, but also on psychological dimensions, such as emotional-wellbeing, mindfulness, impulsivity, and rumination. Here we aimed at exploring these influences on duration estimation and passage of time judgments. One hundred and seventeen healthy individuals filled out mindfulness (FFMQ), impulsivity (BIS-11), rumination (RRS), and depression (BDI-sf) questionnaires. Participants also conducted verbal estimation and production tasks in the multiple seconds range. During these timing tasks, (...) subjects were asked to read digits aloud that were presented on a computer screen. Each condition of the timing tasks differed in terms of the interval between the presentation of the digits, i.e., either short (4-s) or long (16-s). Our findings suggest that long empty intervals (16-s) are associated with a relative underestimation of duration, and to a feeling that the time passes slowly, a seemingly paradoxical result. Also, regarding more mindful individuals, such a dissociation between duration estimation and passage of time judgments was found, but only when empty intervals were short (4-s). Relatively speaking, more mindful subjects showed an increased overestimation of durations, but felt that time passed more quickly. These results provide further evidence for the dissociation between duration estimation and the feeling of the passage of time. We discuss these results in terms of an alerting effect when empty intervals are short and events are more numerous, which could mediate the effect of dispositional mindfulness. (shrink)

Previous research has demonstrated that duration of implied motion (IM) was dilated, whereas hMT+ activity related to perceptual processes on IM stimuli could be modulated by their motion coherence. Based on these findings, the present study aimed to examine whether subjective time perception of IM stimuli would be influenced by varying coherence levels. A temporal bisection task was used to measure the subjective experience of time, in which photographic stimuli showing a human moving in four directions (...) (left, right, toward, or away from the viewer) were presented as probe stimuli. The varying coherence of these IM stimuli was manipulated by changing the percentage of pictures implying movement in one direction. Participants were required to judge whether the duration of probe stimulus was more similar to the long or short pre-presented standard duration. As predicted, the point of subjective equality was significantly modulated by the varying coherence of the IM stimuli, but not for no-IM stimuli. This finding suggests that coherence level might be a key mediating factor for perceived duration of IM images, and top-down perceptual stream from inferred motion could influence subjective experience of time perception.

Many prepared actions have to be withheld for a certain amount of time in order to have the most beneficial outcome. Therefore, keeping track of time accurately is vital to using temporal regularities in our environment. Traditional theories assume that time is tracked by means of a clock and an “attentional gate” (AG) that modulates subjective time if not enough attentional resources are directed toward the temporal process. According to the AG theory, the moment of (...) distraction does not have an influence on the subjective modulation. Here, we show, based on an analysis of 28,354 datasets, that highly motivated players of the online multiplayer real‐time strategy game StarCraft2 indeed respond later to timed events when they are distracted by other tasks during the interval. However, transient periods of distraction during the interval influence the response time to a lesser degree than distraction just before the required response. We extend the work of Taatgen, van Rijn, and Anderson (2007) and propose an alternative active check theory that postulates that distracted attention prevents people from checking their internal clock; we demonstrate that this account better predicts variance observed in response time. By analyzing StarCraft2 data, we assessed the role of attention in a naturalistic setting that more directly generalizes to real‐world settings than typical laboratory studies. (shrink)

It is often held that, in contrast to Husserl, Heidegger's account of intentionality makes no essential reference to the first- person stance. This paper argues, on the contrary, that an account of the first- person, or 'subjectivity', is crucial to Heidegger's account of intelligibility and so of the intentionality, or 'aboutness' of our acts and thoughts, that rests upon it. It first offers an argument as to why the account of intelligibility in Division I of Being and Time, based (...) on a form of third- person self-awareness, provides a necessary, but not a sufficient, condition for intentionality. It then shows that Heidegger provides a further necessary condition in his analysis of the collapse of the one-self in Division II. This condition is 'conscience', which is both a genuine first- person mode of self-awareness and, it is argued, the origin of reason as that which distinguishes factic 'grounds' from normative 'justifications'.

This article examines the emergence of a ‘financial subject’ in the transformation of the UK economy since 1979, using a critical realist approach to subjectivity that investigates underlying causal mechanisms and structures as they affect daily life. Financial restructuring, including widespread borrowing and increasing personal investment, has forged links between finance markets and personal finance, as workers’ wages are financialized. This engenders entrepreneurial subjectivity, with individuals interpellated to be self-reliant in managing possible risks. It argues that the process of subjectivation, (...) where individuals recognize themselves and their goals relative to financial markets, exemplifies the development of financialization itself, since it gives an insight into the successful reproduction of social relations of finance. It illustrates the instability related to wages and inequality, as some subjects have to contend with unpredictable employment prospects as potential future risks that complicate the practices of personal investment and borrowing, creating new hierarchies bound up with the financialization of the economy.

This paper explores the events surrounding a string of robberies from the homes of young celebrities living in Los Angeles County by a group of teenagers referred to by the media as “The Bling Ring.” It argues that the group demonstrates the intersections of desire and materiality under the conditions of a culture driven by idolization of the celebrity, referring to the works of Jean Baudrillard, Pierre Bourdieu, and French collective Tiqqun. It further examines the events as a moment where (...) subjects were able to escape the life-narratives imposed upon them by the State. Rather than adhering to the norms of regular adolescent life, reproduced and enforced through what Michael Shapiro identifies as “national-time,” members of the Bling Ring endeavored to create their own lives according to what I refer to as “celebrity-time,” revealing processes of becoming in the work of Gilles Deleuze, and plasticity in that of Catherine Malabou.

This study examined the extent to which individual differences in time perspective, i.e. habitual way of relating to the personal past, present, and future, are associated with sleep quality and daytime sleepiness in a sample of older adults. The participants (N = 437, 60-90 years) completed the Karolinska Sleep Questionnaire (KSQ), a version of the Zimbardo Time Perspective Inventory (S-ZTPI) and two ratings of SWB (life satisfaction, happiness). Based on established relationships between dimension of time perspective and (...) other variables (e.g. depression) and relations between negative retrospection (rumination) and negative prospection (worry) in prior studies, we expected higher scores on Past Negative and Future Negative to be linked to poor sleep quality and (indirectly) increased daytime sleepiness. Moreover, we examined the possibility that variations in perceived sleep and sleepiness during the day mediates the expected association between an aggregate measure of deviations from a so called balanced time perspective (DBTP) and subjective well-being (SWB). In regression analyses controlling for demographic factors (age, sex, work status), higher scores on Past Negative and Future Negative predicted poorer sleep quality and higher levels of daytime sleepiness. Additionally, most of the association between time perspective and daytime sleepiness was accounted for by individual differences in sleep quality. Finally, structural equation modelling yielded results consistent with the hypothesis that variations in sleep mediate part of the negative relationship between DBTP and SWB. Given that good sleep is essential to multiple aspects of health, future studies evaluating relationships between time perspective and adverse health outcomes should consider sleep quality as a potentially contributing factor.

In this chapter we examine the tendency to view future-oriented mental time travel as a unitary faculty that, despite task-driven surface variation, ultimately reduces to a common phenomenological state. We review evidence that FMTT is neither unitary nor beholden to episodic memory: Rather, it is varied both in its memorial underpinnings and experiential realization. We conclude that the phenomenological diversity characterizing FMTT is dependent not on the type of memory activated during task performance, but on the kind of (...) class='Hi'>subjective temporality associated with the memory in play.

Balanced time perspective is associated with optimal social functioning and facilitates adaptation to pressure and changes in the environment. Previous studies have found that mindfulness is positively associated with and might promote balanced time perspective. However, the mechanism through which mindfulness affects balanced time perspective remains unexplored. The purpose of the present study was to investigate the mediating role of self-compassion and subjective well-being in the relationship between mindfulness and balanced time perspective. A total of (...) 754 Chinese college students, aged 17–27 years, completed the Chinese versions of the Five-Facet Mindfulness Questionnaire, Self-Compassion Scale, Subjective Well-Being Scale, and Zimbardo Time Perspective Inventory. There were significant positive correlations between mindfulness, self-compassion, subjective well-being, and balanced time perspective. Structural equation modeling indicated that in addition to the direct influence of mindfulness on balanced time perspective, self-compassion and subjective well-being played a partial mediating role. On the basis of these findings, we conclude that mindfulness has an important positive influence on balanced time perspective, and highlight the crucial role of the self-compassion in cultivating an individual's balanced time perspective. Limitations of the present study are also discussed. (shrink)

The conclusion of physics, within both a historical and more recent context, that an objectively progressive time and present moment are derivative notions without actual physical foundation in nature, illustrate that these perceived chronological features originate from subjective conscious experience and the neurobiological processes underlying it. Using this conclusion as a stepping stone, it is posited that the phenomena of an in-built subjective conception of a progressive present moment in time and that of conscious awareness are (...) actually one and the same thing, and as such, are also the outcome of the same neurobiological processes. A possible explanation as to how this might be achieved by the brain through employing the neuronal induced nonconscious cognitive manipulation of a small interval of time is proposed. The CIP phenomenon, elucidated within the context of this study is also then discussed. (shrink)

Resumen: En este artículo presentamos a san Agustín como punto de partida de la reflexión de Husserl respecto del tiempo y la correlación entre memoria y Erinnerung. La investigación fenomenológica de Husserl acerca de la conciencia interna del tiempo parte de la reflexión de san Agustín por el mismo problema. En estas obras, el tiempo se puede medir porque hay una distentio animi. En Husserl, Die Erinnerung nos coloca ante una conexión infinita de “antes”, pues toda percepción se encuentra en (...) una relación de multiplicidad de percepciones. Ambos pensadores están unidos por la vocación de dar cuenta de la propia inmanencia.: This article presents Saint Agustin as a starting point for Husserl’s reflection on time and the correlation between memory and Erinnerung. Husserl’s phenomenological research on the internal consciousness of time starts from the reflection of St. Augustine on the same problem. In this works, time can be measured because there is distentio animi. In Husserl, Die Erinnerung places us in the face of an infinite “before” connection, because all perceptions are to be found on a relationship of multiplicity of perceptions. Both thinkers are united by the vocation to account for their own immanence. (shrink)

Four experiments examined how accurately participants can report the times of their own decisions. Within an auditory reaction time task, participants reported the time at which the tone was presented, they decided on the response, or the response key was pressed. Decision time reports were checked for plausibility against the actual RTs, and we compared the effects of experimental manipulations on these two measures to see whether the reported decision times showed appropriate effects. In addition, we estimated (...) the amount of error associated with individual decision time reports by checking how often participants’ decision time reports were implausibly early or late , and by using several quantitative models. Overall, the results suggest that decision time reports are not very accurate but they may be usable for some purposes. (shrink)
