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 subjective (...) temporality associated with the memory in play.

The kappa effect is a well-reported phenomenon in which spatial distance between discrete stimuli affects the perception of temporal distance demarcated by the corresponding stimuli. Here, we report a new phenomenon that we propose to designate as thelexical kappa effectin which word distance, a non-magnitude relationship of discrete stimuli that exists in the lexical space of the mental lexicon, affects the perception of temporal distance. A temporal bisection task was used to assess the subjective perception of the time interval (...) demarcated by two successively presented words. Word distance was manipulated by varying the semantic (Experiment 1) or phonological (Experiment 2) similarity between the two words. Results showed that the temporal distance between the two words was perceived to be shorter when the corresponding two words were lexically closer. We explain this effect within the internal clock framework by assuming faster detection of the word that terminated timing when it is preceded by a semantically or phonologically similar word.

Disturbances of perception of subjective time have been described in schizophrenia but have not been experimentally studied until now. We investigated how patients with schizophrenia estimate the subjective temporal distance of past personal events, i.e. how these events are perceived as subjectively close or distant in time. Twenty-five patients with schizophrenia and 25 control participants recalled 24 autobiographical memories from four different life periods. They estimated the subjective TD and rated the amount of detail of each memory. (...) Results showed that patients with schizophrenia had a distorted perception of subjective TD. Their memories were significantly less detailed than those of controls and, unlike control participants, the amount of memory detail was not significantly correlated with subjective TD. Poor access to memory detail may account for distortions of perception of subjective time in patients with schizophrenia. (shrink)

Although the dream narrative, of (bio)logical necessity, originates with the dreamer, s/he typically does not know this. For the dreamer, the dream world is the real world. In this article I argue that this nightly misattribution is best explained in terms of the concept of mental ownership (e.g., Albahari, 2006; Klein, 2015a; Lane, 2012). Specifically, the exogenous nature of the dream narrative is the result of an individual assuming perspectival, but not personal, ownership of content s/he authored (i.e., “The content (...) in my head is not mine. Therefore it must be peripherally perceived”). Situating explanation within a theoretical space designed to address questions pertaining to the experienced origins of conscious content has a number of salutatory consequences. For example, it promotes predictive fecundity by bringing to light empirical generalizations whose presence otherwise might have gone unnoticed (e.g., the severely limited role of mental time travel within the dream narrative). -/- .

Interdisciplinary perspectives on the feature of conscious life that scaffolds every act of cognition: subjective time. Our awareness of time and temporal properties is a constant feature of conscious life. Subjective temporality structures and guides every aspect of behavior and cognition, distinguishing memory, perception, and anticipation. This milestone volume brings together research on temporality from leading scholars in philosophy, psychology, and neuroscience, defining a new field of interdisciplinary research. The book's thirty chapters include selections from classic texts by (...) William James and Edmund Husserl and new essays setting them in historical context; contemporary philosophical accounts of lived time; and current empirical studies of psychological time. These last chapters, the larger part of the book, cover such topics as the basic psychophysics of psychological time, its neural foundations, its interaction with the body, and its distortion in illness and altered states of consciousness.

This book seeks to arrive at a better understanding of the relationships between the objective and subjective aspects of time. It discusses the existence of fluent time, a controversial concept in many areas, from philosophy to physics. Fluent time is understood as directional time with a past, a present and a future. We experience fluent time in our lives and we adopt a temporal perspective in our ways of knowing and acting. Nevertheless, the existence of fluent time has been (...) debated for both philosophical and scientific reasons, thus creating a rift between the subjective and objective aspects of time. Starting from the basic notion of points of view, or perspectives, this book explores the relationships between objective or external time, as it has been conceptualized by science, and subjective or internal time, which is involved in our lived experiences. It establishes a general framework encompassing the nature, structure and mode of existence of points of view, in which the objective and subjective aspects of time can be integrated. The book mainly addresses researchers and postgraduates in philosophy and logic. Additionally, it offers inspiration for physicists and computer scientists involved in the modeling and simulation of complex behaviors for which the representation of internal time should be considered together with the notion of objective, external time.

Both in its methods and spirit, Kant’s critical philosophy seems the opposite of recent French philosophy. In its deductive approach, it exemplifies a severe rationality; its structures of argument and proof often abstract from our lived experience. The philosophies of Derrida and Levinas, however, attend to such experience. In particular, they are sensitive to precisely those aspects of it that seem to exceed our conceptual abilities. Thus, for Levinas the face of the other manifests an “inabsorbable alterity.” It cannot be (...) integrated.. (shrink)

Jason Stanley has argued recently that Epistemic Contextualism (EC) and Subject‐Sensitive Invariantism (SSI) are explanatorily on a par with regard to certain data arising from modal and temporal embeddings of ‘knowledge’‐ascriptions. This paper argues against Stanley that EC has a clear advantage over SSI in the discussed field and introduces a new type of linguistic datum strongly suggesting the falsity of SSI.

Common wisdom, philosophical analysis and psychological research share the view that memory is subjectively positioned toward the past: Specifically, memory enables one to become re-acquainted with the objects and events of his or her past. In this paper I call this assumption into question. As I hope to show, memory has been designed by natural selection not to relive the past, but rather to anticipate and plan for future contingencies -- a decidedly future-oriented mode of subjective temporality. This is (...) not to say memory makes no reference to the past. But, I argue, past-oriented subjectivity is a by-product of a system designed by natural selection to help us face and respond to the "now and the next". I discuss the implications of the proposed temporal realignment for research agendas as well as the potential limitations of measures designed to explore memory by focusing on its retentive capabilities.

Many methodologies for systematic study of lived experience have been proposed in recent decades. These methods are typically calibrated in terms of the depth and complexity of data collection, and whether they consider reports on pre-reflective experience admissible. Even though it has been shown that lived experience occurs at different timescales (elementary, integrative, narrative), contemporary methods tend to focus on momentary experience. We trace the focus on momentary experience to the current cultural milieu and attitudes in the history of psychology. (...) We point out the need for studying temporally extended experiences in the field of psychopathology. We propose that lived experiences at different timescales are nested within each other and that this principle can be used to organize data collected with qualitative methods for the study of experience. We suggest that temporally extended experiences occur at the narrative level of description (i.e. they consist of experiential reports and sense-making). (shrink)

Episodic memories are shaped by the representational format of their contents. These formats are not only determined by medial temporal lobe areas, but essentially also by the neocortical regions which these areas control. The representational formats of medial temporal lobe and neocortex are sufficient to determine both, memory contents and subjective memory qualities, without the further need for an attribution system.

Temporal non-dynamists hold that there is no temporal passage, but concede that many of us judge that it seems as though time passes. Phenomenal Illusionists suppose that things do seem this way, even though things are not this way. They attempt to explain how it is that we are subject to a pervasive phenomenal illusion. More recently, Cognitive Error Theorists have argued that our experiences do not seem that way; rather, we are subject to an error that leads us mistakenly (...) to believe that our experiences seem that way. Cognitive Error Theory is a relatively new view and little has been said to explain why we make such an error, or where, in the cognitive architecture, such an error might creep in. In this paper we remedy this by offering a number of hypotheses about the source of error. In so doing we aim to show that Cognitive Error Theory is a plausible competitor to Phenomenal Illusion Theory. (shrink)

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)

Many assume that theories of distributive justice must obviously take people’s lifetimes, and only their lifetimes, as the relevant period across which we distribute. Although the question of the temporal subject has risen in prominence, it is still relatively underdeveloped, particularly in the sphere of health and healthcare. This paper defends a particular view, “momentary sufficientarianism,” as being an important element of healthcare justice. At the heart of the argument is a commitment to pluralism about justice, where theorizing about just (...) principles demands paying attention to the role particular goods play in our lives. This means that different approaches to the temporal subject—as well as other relevant issues—may be appropriate for different goods, including different goods within healthcare. In particular, the paper discusses two central goods targeted by healthcare: life-saving and pain relief. The view is offered as complementary to, rather than competitive with, lifetime approaches. As such, the paper finishes by considering how a pluralist approach, which engages both with people’s lives as a whole and with their states at particular moments, can reconcile the potentially competing claims in healthcare that emerge from these two perspectives.

Maintaining accurate and precise temporal perception under conditions of stress is important. Studies in animal models and clinic patients have suggested that time perception can change under chronic stress. Little is known, however, about the relationship between chronic stress and time perception in healthy individuals. Here, a sample of 62 healthy young men completed Cohen’s Perceived Stress Scale (PSS) as a measure of chronic stress levels, while time perception was measured using a temporal bisection task. This task used short (400 (...) ms) and long (1600 ms) visual signals as anchor durations. Participants were presented with a range of intermediate probe durations and were required to judge whether the durations were more similar to the short or the long anchor. Results showed that chronic stress was negatively related to temporal sensitivity indexed by the Weber ratio. However, there was no significant correlation between chronic stress and subjective duration indexed by the bisection point. These results demonstrate that higher chronic stress is associated with lower temporal sensitivity and thus provide evidence for a link between chronic stress and time perception in healthy adults.

In temporal binding, the temporal interval between one event and another, occurring some time later, is subjectively compressed. We discuss two ways in which temporal binding has been conceptualized. In studies showing temporal binding between a voluntary action and its causal consequences, such binding is typically interpreted as providing a measure of an implicit or pre-reflective “sense of agency”. However, temporal binding has also been observed in contexts not involving voluntary action, but only the passive observation of a cause-effect sequence. (...) In those contexts, it has been interpreted as a top-down effect on perception reflecting a belief in causality. These two views need not be in conflict with one another, if one thinks of them as concerning two separate mechanisms through which temporal binding can occur. In this paper, we explore an alternative possibility: that there is a unitary way of explaining temporal binding both within and outside the context of voluntary action as a top-down effect on perception reflecting a belief in causality. Any such explanation needs to account for ways in which agency, and factors connected with agency, have been shown to affect the strength of temporal binding. We show that principles of causal inference and causal selection already familiar from the literature on causal learning have the potential to explain why the strength of people’s causal beliefs can be affected by the extent to which they are themselves actively involved in bringing about events, thus in turn affecting binding.

Temporal regularities in speech, such as interdependencies in the timing of speech events, are thought to scaffold early acquisition of the building blocks in speech. By providing on-line clues to the location and duration of upcoming syllables, temporal structure may aid segmentation and clustering of continuous speech into separable units. This hypothesis tacitly assumes that learners exploit predictability in the temporal structure of speech. Existing measures of speech timing tend to focus on first-order regularities among adjacent units, and are overly (...) sensitive to idiosyncrasies in the data they describe. Here, we compare several statistical methods on a sample of 18 languages, testing whether syllable occurrence is predictable over time. Rather than looking for differences between languages, we aim to find across languages (using clearly defined acoustic, rather than orthographic, measures), temporal predictability in the speech signal which could be exploited by a language learner. First, we analyse distributional regularities using two novel techniques: a Bayesian ideal learner analysis, and a simple distributional measure. Second, we model higher-order temporal structure—regularities arising in an ordered series of syllable timings—testing the hypothesis that non-adjacent temporal structures may explain the gap between subjectively-perceived temporal regularities, and the absence of universally-accepted lower-order objective measures. Together, our analyses provide limited evidence for predictability at different time scales, though higher-order predictability is difficult to reliably infer. We conclude that temporal predictability in speech may well arise from a combination of individually weak perceptual cues at multiple structural levels, but is challenging to pinpoint. (shrink)

The Schrödinger equation for quantum mechanics, which is approachable in third-person description, takes for granted tenseless time that does not distinguish between different tenses such as past, present, and future. The time-reversal symmetry grounded upon tenseless time globally may, however, be broken once measurement in the form of exchanging indivisible quantum particles between the measured and the measuring intervenes. Measurement breaks tenseless time locally and distinguishes different tenses. Since measurement is about the material process of feeding and acting upon the (...) quantum resources already available from any material bodies to be measured internally, the agency of measurement is sought within the environment in the broadest sense. Most indicative of internal measurement of the environmental origin are chemical reactions in the reaction environment. Temporality naturalized in chemical reactions proceeding as being subjected to frequent interventions of internal measurement is approachable in second-person description because of the participation of multiple agents of measurement there. The use of second-person description is found in the appraisal of the material capacity of generating, distinguishing, and integrating different tenses. An essence of the temporality to be naturalized is within the genesis of different tenses. A most conspicuous exemplar of naturalized temporality is sought in the origins of life conceivable exclusively on the material ground. (shrink)

This essay argues that, while much has been gained by medicine's focus on the spatial aspects of disease in light of developments in modern pathology, too little attention has been given to the temporal experience of illness at the subjective level of the patient. In particular, it is noted that there is a radical distinction between subjective and objective time. Whereas the patient experiences his immediate illness in terms of the ongoing flux of subjective time, the physician (...) conceptualizes the illness as a disease state according to the measurements of objective time. A greater understanding of this disparity in temporal experiencing provides insights into the lived experience of illness and can preclude difficulties in communication between physician and patient.

The Temporal-Order Judgment (TOJ) paradigm has been widely investigated in previous studies as an accurate measure of temporal resolution and sequencing abilities in the millisecond time range. Two auditory TOJ tasks are often used: (1) a spatial TOJ task, in which two identical stimuli are presented in rapid succession monaurally and the task is to indicate which ear received the first stimulus and which ear received the second one ( left-right or right-left ), and (2) a spectral TOJ task, in (...) which two tones of different frequencies are presented asynchronously to both ears binaurally and the task is to report the sequence of these tones ( low-high or high-low ). The previous literature studies conducted on young volunteers indicated that the measured temporal acuity on these two tasks depended on the procedure used. As considerable data are now available about age-related decline in temporal resolution ability, the aim of the present study was to compare in elderly subjects the pattern of performance on these two tasks. A total of 40 normal healthy volunteers aged from 62 to 78 years performed two TOJ tasks. The measurement was repeated in two consecutive sessions. Temporal resolution was indexed by the Auditory Temporal-Order Threshold (ATOT), i.e., the minimum time gap between successive stimuli necessary for a participant to report a before-after relation with 75% correctness. The main finding of the present study was the indication of differences in the elderly in performance on two tasks. In the spatial task, the distribution of obtained ATOT values did not deviate from the Gaussian distribution. In contrast, the distribution of data in the spectral task deviated significantly from the Gaussian and was spread more to the right. Although lower ATOT values were usually observed in Session 2 than in Session 1, such difference was significant only in the spectral task. We conclude that although temporal acuity and sequencing abilities in the millisecond time range are probably based in neuronal oscillatory activity, the measured ATOTs in the elderly seem to be stimulus-dependent, procedure-related, and influenced by the perceptual strategies used by participants.

In temporal counteridenticals like ‘Ian is imagining that it is 2030 and Sally is rich’, the subject locates themself at a time other than (what they believe to be) the current time. In such reports, tense in the embedded clause can denote the time that the attitude holder imagines herself to be located at, or the time that she believes herself to be located at. I show that these two interpretations are subject to systematic constraints. The observed pattern is parallel (...) to that discovered in Pearson (in prep.) for personal counteridenticals, such as Lakoff’s famous Brigitte Bardot sentence. I propose an analysis of these findings that depends on two key assumptions: (1) there is a mechanism of ‘de nunc binding’ that encodes the ‘subjective now’ of the attitude holder; and (2) this mechanism is constrained by a principle of the grammar called ‘Condition CW’, originally proposed for personal counteridenticals in Pearson (in prep.). These findings support the view that attitudes de se and de nunc constitute a special class, not reducible to de re. They further suggest that there is a dedicated linguistic mechanism for encoding such attitudes that is subject to systematic grammatical constraints. (shrink)

Is time based in the physics of inanimate matter, or does it originate in the operation of our minds? Is it essential for the constitution of reality, (...) or is it just an illusion? Issues of time, temporality, and nowness are paradigms for interdisciplinary work in many contemporary fields of research.

Historically one of the recurring problems which philosophers have faced when trying to come to some understanding of causation is the temporal relationship of the cause to the effect.

The goal of this paper is to reduce the number of positions concerning the temporal relationship of cause (...) to effect which can be considered adequate to account for the way that causal relationships occur in the world, and the ordinary understanding we have of them.

The article analyzes the philosophical concept of the “porous self” of J. Rivera. The originality of this concept in the post-phenomenological project is determined by the role of theological constructions that modify the primal experience of self-consciousness. This modification allows us to interpret the phenomenological description of the human self as different from the classical — “porous” temporality, i.e., correlating through “two entrances”—the internal and external—with eternity. Within this approach, the primary phenomenon of the constitution of the "porous" self becomes (...) the inner word, which in the appeal to eternity turns out to be the original self-awareness of the self as a temporality. The secondary phenomenon of the constitution of the “porous” self is not the mundane temporality of M. Heidegger, but Epektasis as an intense striving towards the end of time in General. The worldly temporality of the self, transformed by faith, is phenomenologically revealed as open to eternity in each of its moments. The third phenomenon of the temporality of the self is Memoria, whose interpretation reveals how the structure of the inner consciousness of time by E. Husserl can be framed ontologically and harmoniously integrated into the theological concept. The article shows how, based on this understanding of both the internal and external openness of the “porous” self for eternity, the integral structure of its temporality is formed. The temporality of the porous self is a modification of Husserl’s time diagrams and the intertwining of two streams of temporality at the same time from past to future and from future to past, which itself constitutes a phenomenal field of events of self. This understanding of temporality sets new perspectives for the phenomenological analysis of subjectivity. (shrink)

This report concerns the fragmented visual percepts in a woman, TR, following a right entorhinal–perirhinal infarct. In a previous report, Weddell [Weddell, R. A. . A visual disorder producing highly selective deletion of recurring letters. Cortex, 41, 471–485] linked TR’s highly selective tendency to delete recurrent letters with her fragmented percepts. The conflation of same-identity form elements was attributed to anterior extrastriate damage, which reduced the amount of information sustainable in fully resolved visual percepts, and the present experimental investigation of (...) her subjective account of segment formation and resolution completes the story. She said that complex objects and long words first appeared as blurred regions, which sometimes included form elements. It is argued that figure-centred attentional mechanisms subdivided this blurred region into up to 3–4 parts. String length, lexical status , and background colour and/or luminance determined fragment length. Two rules described the fragment resolution sequence: largest segments usually resolved first, left-to-right resolution accounting for a few sequences. This resolution sequence occurred when stimuli were exposed too briefly for saccadic exploration, implicating endogenous attentional shifts. Experiment 4 confirmed TR’s assertion that spatial, orthographic, and phonological information were stored during the fragment resolution process. Moreover, TR exerted considerable voluntarily control over the fragment resolution sequence and some influence over fragment length. Finally, these findings were interpreted in terms of an extended version of a neural network model of vision largely derived from nonhuman primate studies. (shrink)

Objects and events from the outside world are represented in our consciousness through the structure of time. Temporality and consciousness are closely related phenomena and in this paper, I intend to explore their relationship by referring to the philosophy of Edmund Husserl.

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)

The interpretive approach adopted in this paper is influenced by Merleau-Ponty’s philosophy and in particular by his understanding of Nature, which in turn takes into consideration Whitehead’s work. Whitehead’s philosophy of organism is seen by its author as the metaphysical generalization of problems found in his investigation of natural knowledge. Whitehead admits that a speculative approach is necessitated by the very questions arising from the mathematical concepts of the material world and the revolutions undergone in logic, mathematics and physics at (...) the turn of the century.Whitehead’s understanding of nature is framed from the beginning in terms of a processual approach. However, this notion of process is not fully worked out in the epistemological works and requires a metaphysical deepening. This is due to the fact that the notion of duration adopted in the epistemological works is not sufficient to convey the notion of process. This lack of adequacy is coupled by Whitehead with the need to interpret process in terms of experience. In turn, this notion of experience is wider than the usual one, for it implies that there is experience from the lowest levels onwards. Matter itself experiences. Seen in this perspective, reality is thus conceived in terms of a whole in constant change, whose parts are in mutual connection. This conception derives from Whitehead’s criticism of Aristotle’s substantialism and from his preference for a relationist ontology. The outcome of this approach is a speculative conception of reality in terms of a twofold notion of process: concrescence and transition, which Whitehead sees as the two faces of the creative advance of nature. This dual notion of process is interpreted in this essay in a merleau-pontyan perspective. (shrink)

While foregrounding the historiography of HIV and AIDS in the South African context, this article analyses AIDS as simultaneously existing in three spheres: first, virtually – as the subject matter of electronically measurable research; second, academically – as a topic of research in the discipline of History; and third, actually – as a complex health concern and signifier that, via the field of Medical and Health Humanities, could allow for new collaborations between historians and others interested in understanding AIDS. Throughout, (...) the central focus is the discipline of History and the global trends that become evident when examining metrics about AIDS research, particularly those that show the hierarchies of knowledge ‘production’, the reinforcement of disciplinary boundaries, and the discrepancy between the amount of research ‘produced’ by scientific and humanities disciplines. Overall, the article suggests that ‘post-AIDS’ is not currently helpful to health historians working on South African and other majority world contexts. More specifically, the article reflects on what AIDS histories still need to be written, and I argue that Medical and Health Humanities could provide a space for historians to work within and across disciplinary boundaries given the ever evolving remit of AIDS histories, temporalities, and narratives.
