The ability to introspect about self-performance is key human subjective experience, but the neuroanatomical basis of this unknown. Such accurate introspection requires discriminating correct decisions from incorrect ones, a capacity that varies substantially across individuals. We dissociated variation in introspective objective performance simple perceptual-decision task, allowing us determine whether interindividual variability was associated with distinct neural basis. show correlated...
People are often aware of their mistakes, and report levels confidence in choices that correlate with objective performance. These metacognitive assessments decision quality important for the guidance behavior, particularly when external feedback is absent or sporadic. However, a computational framework accounts both error detection lacking. In addition, dissociations between performance metacognition have relied on ad hoc assumptions, precluding unified account intact impaired...
Neuroscience has made considerable progress in understanding the neural substrates supporting cognitive performance a number of domains, including memory, perception, and decision making. In contrast, how human brain generates metacognitive awareness task remains unclear. Here, we address this question by asking participants to perform perceptual decisions while providing concurrent reports during fMRI scanning. We show that activity right rostrolateral prefrontal cortex (rlPFC) satisfies...
This paper outlines a hierarchical Bayesian framework for interoception, homeostatic/allostatic control, and meta-cognition that connects fatigue depression to the experience of chronic dyshomeostasis. Specifically, viewing interoception as inversion generative model viscerosensory inputs allows formal definition dyshomeostasis (as chronically enhanced surprise about bodily signals, or, equivalently, low evidence brain’s states) allostasis change in prior beliefs or predictions which define...
Introspection, or metacognition, is the capacity to reflect on our own thoughts and behaviours. Here, we investigated how one specific metacognitive ability (the relationship between task performance confidence) develops in adolescence, a period of life associated with emergence self-concept enhanced self-awareness. We employed that dissociates objective visual from group 56 participants aged 11 41 years. Metacognitive improved significantly age during was highest late adolescence plateaued...
Many complex systems maintain a self-referential check and balance. In animals, such reflective monitoring control processes have been grouped under the rubric of metacognition. this introductory article to Theme Issue on metacognition, we review recent rapidly progressing developments from neuroscience, cognitive psychology, computer science philosophy mind. While each these areas is represented in detail by individual contributions volume, take opportunity draw links between disciplines,...
Humans have the capacity to evaluate success of cognitive processes, known as metacognition. Convergent evidence supports a role for anterior prefrontal cortex in metacognitive judgements perceptual processes. However, it is unknown whether metacognition global phenomenon, with supporting across domains, or relies on domain-specific neural substrates. To address this question, we measured accuracy patients lesions (n = 7) two distinct perception and memory, by assessing correspondence...
Metacognition refers to the ability reflect on and monitor one's cognitive processes, such as perception, memory decision-making. is often assessed in lab by whether an observer's confidence ratings are predictive of objective success, but simple correlations between performance susceptible undesirable influences response biases. Recently, alternative approach measuring metacognition has been developed (Maniscalco Lau 2012) that characterizes metacognitive sensitivity (meta-d') assuming a...
Metacognition is the capacity to evaluate success of one's own cognitive processes in various domains; for example, memory and perception. It remains controversial whether metacognition relies on a domain-general resource that applied different tasks or if self-evaluative are domain specific. Here, we investigated this issue directly by examining neural substrates engaged when metacognitive judgments were made human participants both sexes during perceptual matched stimulus performance...
Significance Recent computational models propose that our sense of confidence in a choice reflects an estimate the probability is correct. However, it has proven difficult to experimentally separate decision from its component parts, such as certainty about perceptual evidence or requirements. We have devised task dissociate these quantities and isolate distinct encoding medial prefrontal cortex human brain. show activity this area not only tracks expected performance on task, but also...

Abstract Metacognition is the capacity to evaluate and control one’s own cognitive processes. operates over a range of domains, such as perception memory, but neurocognitive architecture supporting this ability remains controversial. Is metacognition enabled by common, domain-general resource that recruited performance on variety tasks? Or reliant domain-specific modules? This article reviews recent literature domain-generality human metacognition, drawing evidence from individual...
Abstract A prominent source of polarised and entrenched beliefs is confirmation bias, where evidence against one’s position selectively disregarded. This effect most starkly evident when opposing parties are highly confident in their decisions. Here we combine human magnetoencephalography (MEG) with behavioural neural modelling to identify alterations post-decisional processing that contribute the phenomenon bias. We show holding high confidence a decision leads striking modulation...
Whether current or near-term AI systems could be conscious is a topic of scientific interest and increasing public concern. This report argues for, exemplifies, rigorous empirically grounded approach to consciousness: assessing existing in detail, light our best-supported neuroscientific theories consciousness. We survey several prominent consciousness, including recurrent processing theory, global workspace higher-order theories, predictive processing, attention schema theory. From these we...
Humans are voracious imaginers, with internal simulations supporting memory, planning and decision-making. Because the neural mechanisms imagery overlap those perception, a foundational question is how reality imagination kept apart. One possibility that intention to imagine used identify discount self-generated signals during imagery. Alternatively, because internally generated generally weaker, sensory strength index reality. Traditional psychology experiments struggle investigate this...
