Cognitive control processes involving prefrontal cortex allow humans to overrule and inhibit habitual responses optimize performance in new challenging situations, traditional views hold that cognitive is tightly linked with consciousness. We used functional magnetic resonance imaging investigate what extent unconscious “no-go” stimuli are capable of reaching cortical areas involved inhibitory control, particularly the inferior frontal (IFC) pre-supplementary motor area (pre-SMA)....
Perceptual decision-making is highly dependent on the momentary arousal state of brain, which fluctuates over time a scale hours, minutes, and even seconds. The textbook relationship between task performance captured by an inverted U-shape, as put forward in Yerkes–Dodson law. This law suggests optimal at moderate levels impaired low or high levels. However, despite its popularity, evidence for this humans mixed best. Here, we use pupil-indexed data from various perceptual tasks to provide...
To further our understanding of the function conscious experience we need to know which cognitive processes require awareness and do not. Here, show that an unconscious stimulus can trigger inhibitory control processes, commonly ascribed mechanisms. We combined metacontrast masking paradigm Go/No-Go study whether No-Go signals actively high-level strongly associated with prefrontal cortex (PFC). Behaviorally, sometimes triggered response inhibition level complete termination yielded a slow...
Here we review studies on the complexity and strength of unconscious information processing. We focus empirical evidence that relates awareness to cognitive control processes (e.g., response inhibition, conflict resolution, task-switching), life-time maintenance working memory) possibility integrate multiple pieces across space time. Overall, results paint a picture local specific effects various (high-level) brain regions, including areas in prefrontal cortex. Although this neural...
Failures to perceive visual stimuli lead errors in decision making. Different theoretical accounts implicate either medial frontal (MF) cognitive control processes or prestimulus occipital (OC) cortical oscillatory dynamics during perceptual tasks. Here, we show that these 2 previously unconnected can be reconciled, and the brain regions described by theories have complimentary interactive roles supporting error adaptation. Using a discrimination task time–frequency network-based analyses of...
How do expectations influence transitions between unconscious and conscious perceptual processing? According to the influential predictive processing framework, content is determined by models of causes sensory signals. On one interpretation, contents arise when are verified matching input (minimizing prediction error). another, surprising events falsify current predictions. Finally, cognitive impenetrability account posits that perception not affected such higher level factors. To...
Theories about the functional relevance of consciousness commonly posit that higher order cognitive control functions, such as response inhibition, require consciousness. To test this assertion, authors designed a masked stop-signal paradigm to examine whether inhibition could be triggered and initiated by stop signals, which inform participants an action they have begun. In 2 experiments, signals were observed occasionally result in full well yield slow down speed responses not inhibited....
In recent years, time-resolved multivariate pattern analysis (MVPA) has gained much popularity in the of electroencephalography (EEG) and magnetoencephalography (MEG) data. However, MVPA may appear daunting to those who have been applying traditional analyses using event-related potentials (ERPs) or fields (ERFs). To ease this transition, we recently developed Amsterdam Decoding Modeling (ADAM) toolbox MATLAB. ADAM is an entry-level that allows a direct comparison ERP/ERF results any dataset...
What are the limits of unconscious language processing? Can circuits process simple grammatical constructions unconsciously and integrate meaning several unseen words? Using behavioural priming electroencephalography (EEG), we studied a specific rule-based linguistic operation traditionally thought to require conscious cognitive control: negation valence. In masked paradigm, two words were successively (Experiment 1) or simultaneously presented 2), modifier ('not'/'very') an adjective (e.g....
Auditory novelty detection has been associated with different cognitive processes. Bekinschtein et al. (2009) developed an experimental paradigm to dissociate these processes, using local and global novelty, which were associated, respectively, automatic versus strategic perceptual processing. They have mostly studied event-related potentials (ERPs), but spiking activity as indexed by gamma (60–120 Hz) power interactions between brain regions modulations in beta-band (13–25 functional...
Abstract We report the results of an academic survey into theoretical and methodological foundations, common assumptions, current state field consciousness research. The consisted 22 questions was distributed on two different occasions annual meeting Association Scientific Study Consciousness (2018 2019). examined responses from 166 researchers with backgrounds (e.g. philosophy, neuroscience, psychology, computer science) at various stages their careers junior/senior faculty...
When interacting with the dynamic world, brain receives outdated sensory information, due to time required for neural transmission and processing. In motion perception, may overcome these fundamental delays through predictively encoding position of moving objects using information from their past trajectories. present study, we evaluated this proposition multivariate analysis high temporal resolution electroencephalographic data. We tracked representations at different stages visual...
Abstract Cognitive control allows humans to overrule and inhibit habitual responses optimize performance in challenging situations. Contradicting traditional views, recent studies suggest that cognitive processes can be initiated unconsciously. To further capture the relation between consciousness control, we studied dynamics of inhibitory when triggered consciously versus unconsciously a modified version stop task. Attempts an imminent response were often successful after unmasked (visible)...
In conflict tasks such as the Stroop, Eriksen flanker or Simon task, it is generally observed that detection of in current trial reduces impact conflicting information subsequent trial; a phenomenon termed adaptation. This higher-order cognitive control function has been assumed to be restricted cases where experienced consciously. present experiment we manipulated awareness conflict-inducing stimuli metacontrast masking paradigm directly test this assumption. Conflicting response tendencies...
The presupplementary motor area (pre-SMA) is considered key in contributing to voluntary action selection during response conflict. Here we test whether individual differences the ability select appropriate actions face of strong (conscious) and weak (virtually unconscious) distracting alternatives are related variability pre-SMA anatomy. To this end, scanned 58 participants, who performed a masked priming task which conflicting tendencies were elicited either consciously (through primes...
The human brain has the extraordinary capability to transform cluttered sensory input into distinct object representations. For example, it is able rapidly and seemingly without effort detect categories in complex natural scenes. Surprisingly, category tuning not sufficient achieve conscious recognition of objects. What neural process beyond extraction might elevate representations level where objects are consciously perceived? Here we show that visible invisible faces produce similar...
Predictive coding models propose that predictions (stimulus likelihood) reduce sensory signals as early primary visual cortex (V1), and attention relevance) can modulate these effects. Indeed, both prediction have been shown to V1 activity, albeit with fMRI, which has low temporal resolution. This leaves it unclear whether effects reflect a modulation of the first feedforward sweep information processing and/or later, feedback-related activity. In two experiments, we used...
It is well known that top-down expectations affect perceptual processes. Yet, remarkably little about the relationship between and conscious awareness. We address three crucial outstanding questions: (1) how do likelihood of stimulus perception?; (2) does brain register violations nonconsciously?; (3) need to be influence decisions? Using human participants, we performed experiments in which manipulated predictability within attentional blink paradigm, while combining visual psychophysics...
The study of unconscious processing requires a measure conscious awareness. Awareness measures can be either subjective (based on participant's report) or objective perceptual performance). preferred awareness depends the theoretical position about consciousness and may influence conclusions extent neural correlates consciousness. We obtained functional magnetic resonance imaging (fMRI) measurements from 43 subjects while they viewed masked faces houses that were subjectively objectively...
In the search for neural basis of conscious experience, perception and cognitive processes associated with reporting are typically confounded as activity is recorded while participants explicitly report what they experience. Here, we present a novel way to disentangle from using eye movement analysis techniques based on convolutional networks neurodynamical analyses information theory. We use bistable visual stimulus that instantiates two well-known properties perception: integration...
