DESCRIPTION:*Abstract*\nMetacognition refers to the capacity to reflect on
  our own cognition and mental states\, and can be quantified by the extent
  to which subjective appraisals (such as confidence) track behavioural per
 formance. Alterations in metacognition and self-awareness are often consid
 ered foundational to neurological and psychiatric disorders\, but remain u
 nderinvestigated in the cognitive neurosciences. In my talk I will focus o
 n estimates of decision confidence as a testbed for models of metacognitio
 n. I will outline how we can derive metrics of metacognitive bias and sens
 itivity from confidence rating data\, and use these metrics to isolate met
 acognitive distortions that map onto transdiagnostic symptom clusters in l
 arge-N datasets. I will then present recent work aimed at understanding th
 e hierarchical structure of metacognition\, ranging from local confidence 
 in individual decisions to global estimates of skills and abilities. Combi
 ning brain imaging and computational modeling we have uncovered distinct n
 eurocognitive underpinnings of global and local metacognition. I will clos
 e by outlining a theoretical framework in which interactions between these
  levels play a pivotal role in mental health.\n\n*Biography* Dr Stephen Fl
 eming is a Sir Henry Dale Wellcome Trust/Royal Society Fellow at the Depar
 tment of Experimental Psychology\, Prinicipal Investigator at the Wellcome
  Centre for Human Neuroimaging\, and Group Leader at the Max Planck-UCL Ce
 ntre for Computational Psychiatry and Ageing Research. Dr Fleming's resear
 ch combines experimental and theoretical approaches (psychophysics\, compu
 tational modelling\, neuroimaging) to understand how people become self-aw
 are of aspects of their cognition and behaviour (such as perception\, memo
 ry and decision-making)\, and why such awareness is often impaired in psyc
 hiatric and neurological disorders. For detailed biography of Dr Fleming\,
