Andrew, Elisa and Steve have been involved with the Dear World Project, a cross-disciplinary public engagement collaboration that pairs artists and scientists to explore mental health. Their artwork, created by Nicole Morris, Tom Berry and Cathryn Shilling, was displayed in an exhibition as part of a wider collaboration with the Wellcome Centre for Human Neuroimaging and Max Plank Centre for Computational Psychiatry.
Nadine Dijkstra has received two prestigious postdoctoral fellowships to support her work on perceptual awareness and reality monitoring in the lab - a Rubicon Fellowship from the NWO and a Marie Curie Fellowship from the EU. Congratulations Nadine!
A big welcome to new lab members Nadine Dijkstra, Nadim Atiya and Oliver Warrington!
See the people page for more about them and their research plans.
Last year’s MetaLab Masters student Lion Schulz has been awarded the “Best student of the year award” for achieving the highest overall academic performance in UCL’s Cognitive and Decision Sciences MSc. Congratulations to Lion and his supervisor Max!
Steve and Matan were interviewed about consciousness for The Why Factor on the BBC World Service.
There are two programmes - in the first we discuss “Why are we conscious of so little?”, and in the second, “What is the point of consciousness?”
Links below, enjoy!
MetaLab Masters student Roy Tal has been awarded the 2019 Richard Frackowiak MSc Prize for the highest scoring student on UCL’s MSc Brain and Mind Sciences. Congratulations to Roy and his supervisor Matan!
Seeing Culture in Our Brain was given an honorable mention in SFN’s 2019 Brain Awareness Video Contest. Congratulations Keer!
Steve was interviewed by CUNY philosopher Richard Brown for his great YouTube series Consciousness Live - very much unscripted and lots of fun! Amongst other things we talked about science writing, metacognition, generative models, consciousness and the prefrontal cortex.
We are sad to say goodbye to Marion Rouault who is leaving the lab to take up a new position at the Ecole Normale Supérieure in Paris. Marion was one of the founding members of the MetaLab, and had a fantastically productive few years here in London - we will greatly miss having her around, and wish her all the best for her next steps!
We had a lab picnic on a lovely spring evening on Primrose Hill to give Marion a fitting send off:
MetaLab Masters student Lion Schulz will take up a PhD position with Peter Dayan at the Max Planck Institute for Biological Cybernetics in September. Congratulations to Lion!
Xiao’s paper on a role for metacognition in cognitive offloading to the environment has now been published in Cognition. A Twitter thread summarising the findings can be found here:

Matan has been awarded a prestigious UCL Bogue Fellowship to study how self-models of attention and perception form and develop over infancy and childhood and to characterise these models in adults. Matan plans to use this award to fund a visit to Josh Tenenbaum's lab at MIT for 3 months later this year. Congratulations to Matan!
Congratulations to Steve who has been awarded the 2019 Spearman Medal, the premier early career award from the British Psychological Society!

Marion’s paper entitled “Forming global estimates of self-performance from local confidence” has been published in Nature Communications.
A blog post by Marion summarizing the findings is here.
In the paper we developed a new paradigm to investigate how external feedback and local decision confidence relate to global self-performance estimates (SPEs) , and whether local fluctuations in decision confidence inform SPEs when external feedback is unavailable. We showed that fluctuations in confidence contribute to global SPEs over and above effects of objective performance and reaction times. Surprisingly, we found that humans tend to underestimate their performance in the absence of feedback, compared with a condition with full feedback, despite objective performance being similar in the two cases. We hope that study of global self-beliefs formation will advance our understanding of self-efficacy distortion in psychiatric disorders.
Max’s paper entitled "Metacognitive Failure as a Feature of Those Holding Radical Beliefs" has been published in Current Biology.
Figure 4. Individual differences in radicalism are captured by a choice bias model.
We found that radical participants (as measured by scores on dogmatism and authoritarianism questionnaires) showed reduced insight into the correctness of their choices and less sensitivity to post-decision evidence, indicating a generic resistance to revising mistakes. The effect sizes were small, but robust and replicable in a second independent dataset. Given that the tasks were far removed from real-world issues we think it’s striking that basic difference in metacognition predict answers to questions indicative of radical beliefs. A blogpost unpacking these findings further can be found here.
MetaLab postdoc Dan Bang has been awarded a 4-year Sir Henry Wellcome Fellowship by the Wellcome Trust to work on linking neurochemistry, confidence and social context. He plans to split his time between Harvard University (with Sam Gershman), Wake Forest University (with Ken Kishida) and UCL. Congratulations to Dan!
A paper entitled "Human Metacognition Across Domains: Insights from Individual Differences and Neuroimaging" has been published in Personality Neuroscience. Congratulations to Marion and Andy!
The article reviews recent literature on the domain-generality of human metacognition, drawing on evidence from individual differences, behavioural studies and neuroimaging. A meta-analysis of behavioural studies found perceptual metacognitive ability being correlated across different sensory modalities, but not between metacognition of perception and memory. Evidence from neuroimaging studies provided a complementary perspective on the domain-generality of metacognition, revealing co-existence of neural signatures that are common and distinct across tasks.
Figure 5. Different methodologies for quantifying brain structure and function shed light on the underpinnings of metacognition across domains.
Steve has been awarded a 2018 Philip Leverhulme Prize for Psychology from the Leverhulme Trust, together with Prof. Nichola Raihani (also at UCL), Prof. Emily Cross, Dr. Claire Haworth and Dr. Harriet Over. Leverhulme awards are granted annually in recognition of the international impact and future potential of the work. Steve plans to use the £100k award to support work in the lab developing new models of conscious awareness. Read more here!
