Supporting Online Material for Relating Introspective Accuracy to Individual Differences in Brain Structure
TLDR
It is shown that introspective ability is correlated with gray matter volume in the anterior prefrontal cortex, a region that shows marked evolutionary development in humans, and this findings point to a focal neuroanatomical substrate for introspection ability, a substrate distinct from that supporting primary perception.About:

Experimental and Theoretical Approaches to Conscious Processing
TL;DR: Converging neuroimaging and neurophysiological data point to objective neural measures of conscious access: late amplification of relevant sensory activity, long-distance cortico-cortical synchronization at beta and gamma frequencies, and "ignition" of a large-scale prefronto-parietal network.

The structural basis of inter-individual differences in human behaviour and cognition
TL;DR: It is proposed that inter-individual differences can be used as a source of information to link human behaviour and cognition to brain anatomy.

Knowing your own heart: distinguishing interoceptive accuracy from interoceptive awareness.
Sarah N. Garfinkel,Sarah N. Garfinkel,Anil K. Seth,Adam B. Barrett,Keisuke Suzuki,Hugo D. Critchley +5 more
TL;DR: Empirical support for dissociation between dimensions of interoceptive accuracy, sensibility and awareness is provided and set the context for defining how the relative balance of accuracy, Sensibility and Awareness dimensions explain cognitive, emotional and clinical associations of interOceptive ability.

How to measure metacognition
TL;DR: Other measures based on signal detection theory and receiver operating characteristics (ROC) analysis that are “bias free,” are reviewed, and these quantities are related to the calibration and discrimination measures developed in the probability estimation literature.

TL;DR: It is argued that the defining feature of “primary states” is elevated entropy in certain aspects of brain function, such as the repertoire of functional connectivity motifs that form and fragment across time, and that this entropy suppression furnishes normal waking consciousness with a constrained quality and associated metacognitive functions, including reality-testing and self-awareness.

Evaluation of a 'bias-free' measure of awareness.
Simon Evans,Paul Azzopardi +1 more
TL;DR: Kunimoto's measure of awareness a' is not as impervious to response bias as was originally assumed, and results were found when a' was calculated from pre-existing data obtained from a patient with blindsight, which is inconsistent with his well-documented lack of awareness.
Journal ArticleDOI
Signal detection theory, the approach of choice: model-based and distribution-free measures and evaluation.
TL;DR: In this article, the bias of a receiver-operating characteristic (ROC) function was measured using an area-based measure of response bias, and the results showed that response bias for a full ROC function was larger than bias at the cut point and also provided additional information.

Individual Differences in True and False Memory Retrieval Are Related to White Matter Brain Microstructure
Lluís Fuentemilla,Estela Camara,Thomas F. Münte,Ulrike M. Krämer,Toni Cunillera,Josep Marco-Pallarés,Claus Tempelmann,Antoni Rodríguez-Fornells +7 more
TL;DR: It is shown in humans that microstructural properties of different white matter tracts as quantified using diffusion tensor imaging are strongly correlated with true and false memory retrieval and that individual differences in white matter microstructure underlie true andfalse memory performance.

Individual Differences in Metacognitive Responsiveness: Cognitive and Personality Correlates.
TL;DR: Examination of how optimally 124 participants used an uncertain response on near-threshold trials of a psychophysical task suggested that response competition might provide a mechanism for the cognitive experience of uncertainty.

The spatial and temporal construction of confidence in the visual scene.

TL;DR: This study compared the dynamics of objective performance with a measure of subjective report and observed that objective performance beyond explicit subjective reports (blindsight) was significantly more pronounced within a short temporal interval and within specific locations of the visual field which were robust across sessions.
