The Time Loop as a Temporal Loupe: Epistemic Structure and the Magnification of Subjective Experience in Edge of Tomorrow (2014)
As a prime example of the time loop genre, Edge of Tomorrow (Doug Liman, 2014) deals with the experience of time. But not only does it present the macroscopic time distortion of a character trapped in a day-long time loop; it also draws the viewer to experience the characters’ subjective dimensions of the instant. Doing so, it proposes a psychological exploration that is relevant even for us ordinary denizens of non-looping time. In this article,…

States of mind: Towards a common classification of mental states
Addresses the critical challenge of describing and measuring the stream of thought, offering a framework that serves as a useful tool in understanding variations in mental states during cognitive processing. • Proposing a taxonomy called the Classification of Mental States (CoMS-5T), categorising mental states into five tiers based on first-order thought content. • Construct Validity of the CoMS-5T by demonstrating its efficacy in capturing indiv…
Dynamics of spontaneous thoughts: Investigating the links between tendency for exploration, attentional profile and the stream of thoughts
For a long time, clinical knowledge and first-person reports have pointed to individual differences in the dynamics of spontaneous thoughts, in particular in the extreme case of psychiatric conditions (e.g. racing thoughts in Attention Deficit / Hyperactivity Disorder, ADHD; rumination in depression). We used a novel procedure to investigate this individual variability by combining verbal fluency tasks and introspective reports of thought content…
A non-verbal Process Dissociation Procedure to disentangle explicit from implicit sequence learning
Human adults have the ability to extract regularities through implicit learning, resulting in nonconscious knowledge, or through explicit learning, leading to conscious and reportable knowledge. To date, our understanding of the emergence of these two learning processes during development and throughout evolution remains limited. This is partly due to the methodological challenges involved in probing consciousness in preverbal or nonverbal popula…
Dynamics of spontaneous thoughts: Exploration, attentional profile and the segmentation of the stream of thoughts
For a long time, clinical knowledge and first-person reports have pointed to individual differences in the dynamics of spontaneous thoughts, in particular in the extreme case of psychiatric conditions (e.g. racing thoughts in Attention Deficit / Hyperactivity Disorder, ADHD; rumination in depression).

Consensus Goals in the Field of Visual Metacognition
Despite the tangible progress in psychological and cognitive sciences over the last several years, these disciplines still trail other more mature sciences in identifying the most important questions that need to be solved. Reaching such consensus could lead to greater synergy across different laboratories, faster progress, and increased focus on solving important problems rather than pursuing isolated, niche efforts. Here, 26 researchers from th…
Chapitre 4. Quelles données subjectives pour l’étude du flux de conscience
Jrme Sackur stresses that the study of consciousness cannot be limited to snapshots of conscious states. According to him, consciousness is a permanent flow, a "flowing river". This flow of consciousness varies constantly both in intensity and in speed. He first presents so-called "experience sampling" techniques for exploring in children, at all times, the reaction to stimuli involved in a task that these children are performing. He thus highlig…

Resilience of perceptual metacognition in a dual-task paradigm
Difficult Turned Easy: Suggestion Renders a Challenging Visual Task Simple
Suggestions can cause some individuals to miss or disregard existing visual stimuli, but can they infuse sensory input with nonexistent information? Although several prominent theories of hypnotic suggestion propose that mental imagery can change our perceptual experience, data to support this stance remain sparse. The present study addressed this lacuna, showing how suggesting the presence of physically absent, yet critical, visual information t…
The Confidence Database
Understanding how people rate their confidence is critical for the characterization of a wide range of perceptual, memory, motor and cognitive processes. To enable the continued exploration of these processes, we created a large database of confidence studies spanning a broad set of paradigms, participant populations and fields of study. The data from each study are structured in a common, easy-to-use format that can be easily imported and analys…
Temporal dynamics of the hypnotic response
To establish the temporal dynamics of hypnotic responding, we composed an Attentional Blink paradigm in which both the first and second targets were faces, either expressing neutral or angry emotions. We then suppressed the emotional advantage of angry faces by means of a “hypnotic numbing” suggestion. Hypnosis attenuated only the emotional salience of the second target (T2), suggesting that hypnosis’ effects were time and resource dependent. Add…
Confidence can be automatically integrated across two visual decisions
Humans can estimate their confidence in making correct decisions, but these confidence judgments are biased by their other estimations, an effect known as confidence leak. However, it remains unclear whether this effect arises automatically. Here, we address this issue by having participants make two visual decisions and give confidence ratings for one or for both decisions within each trial. Using the well-known interaction between task difficul…
Resilience of Perceptual Metacognition in a Dual-Task Paradigm
When people do multiple tasks at the same time, it is often found that their performance is worse relative to when they do those same tasks in isolation. However, one aspect that has received little empirical attention, is whether the ability to monitor and evaluate one’s task performance is also affected by multitasking. How does dual-tasking affect metacognition and its relation to performance? We investigated this question through the use of a…

Meditation focused on self-observation of the body impairs metacognitive efficiency
Introspection during short-term memory scanning
The literature in metacognition has argued for many years that introspective access to our own mental content is restricted to the cognitive states associated with the response to a task, such as the level of confidence in a decision or the estimation of the response time; however, the cognitive processes that underlie such states were deemed inaccessible to participants' consciousness. Here, we ask whether participants could introspectively dist…
Attention or instruction: Do sustained attentional abilities really differ between high and low hypnotisable persons
Previous research has suggested that highly hypnotisable participants ('highs') are more sensitive to the bistability of ambiguous figures-as evidenced by reporting more perspective changes of a Necker cube-than low hypnotisable participants ('lows'). This finding has been interpreted as supporting the hypothesis that highs have more efficient sustained attentional abilities than lows. However, the higher report of perspective changes in highs in…
Attentional Lapses in Attention-Deficit/Hyperactivity Disorder: Blank Rather Than Wandering Thoughts
People with attention-deficit/hyperactivity disorder (ADHD) have difficulties sustaining their attention on external tasks. Such attentional lapses have often been characterized as the simple opposite of external sustained attention, but the different types of attentional lapses, and the subjective experiences to which they correspond, remain unspecified. In this study, we showed that unmedicated children (ages 6–12) with ADHD, when probed during…
Language facilitates introspection: Verbal mind-wandering has privileged access to consciousness
Perceiving Time Differences When You Should Not: Applying the El Greco Fallacy to Hypnotic Time Distortions
The way we experience and estimate time - subjective time - does not systematically correspond to objective time (the physical duration of an event). Many factors can influence subjective time and lead to mental dilation or compression of objective time. The emotional valence of stimuli or the levels of attention or expectancy are known to modulate subjective time even though objective time is constant. Hypnosis too is known to alter people's per…

Règles de projection et règles de calcul
On identifie deux modèles du concept de règle présents dans l'œuvre de Wittgenstein, dès le Tractatus : les règles de projection (ou de traduction) et les règles opératoires (ou de calcul). Dans le cadre conceptuel de ce texte, gouverné par l'indépendance des propositions élémentaires, ces deux modèles sont équivalents. On interprète ensuite les difficultés de Wittengstein avec le concept de phénoménologie, au début des années trente, comme liées…
Conscious, preconscious, and subliminal processing: A testable taxonomy
Sur la notion de cause
Cet article examine les changements idéologiques qui touchent le statut social des femmes, en particulier la maternité et la sexualité. Il analyse la pluralisation des féminismes en articulation avec les mobilisations actuelles contre les violences sexuelles et montre les injonctions paradoxales qui s’exercent sur les femmes. Dans une perspective épistémologique il relie ces évolutions à des mutations conceptuelles significatives qui s’observent …
Limits on Introspection: Distorted Subjective Time During the Dual-Task Bottleneck
Which cognitive processes are accessible to conscious report? To study the limits of conscious reportability, we designed a novel method of quantified introspection, in which subjects were asked, after each trial of a standard cognitive task, to estimate the time spent completing the task. We then applied classical mental-chronometry techniques, such as the additive-factors method, to analyze these introspective estimates of response time. We dem…
