New paper in Nature Communications: Dynamic influences on static measures of metacognition

Desender, K., Vermeylen, L., & Verguts, T. (2022). Dynamic influences on static measures of metacognition. Nature Communications. [pdf] [data & code]

Are we mistaking response caution for metacognition? In our new paper, published in Nature Communications, we show that this might be the case, because measures of metacognitive accuracy that are based on signal detection theory (such as M-ratio) are confounded with response caution. Instead, we propose a novel dynamic measure of metacognitive accuracy, v-ratio, based on evidence accumulation models. Read the tweeprint here.

Consensus goals for the field of visual metacognition (preprint)

Noting that the field of visual metacognition lacks clear consensus goals, Doby Rahnev (Georgia Tech), gathered researchers working in the field to discuss medium and long-term goals for the field. During long an intense virtual meetings, we discussed the big questions we think the field should address, and subsequently wrote a paper about these goals (preprint). The hope is that by explicitly spelling out these goals, the field will make faster progress towards understanding visual metacognition.

JC reflections: Why our philosophies matter to science

“We all have our philosophies, whether or not we are aware of this fact, and our philosophies are not worth very much. But the impact of our philosophies upon our actions and our lives is often devastating.” Karl Popper, Objective knowledge (1972)

This opinion piece was inspired by our two-weekly Journal Club on the topics of the ‘researcher’s degrees of freedom’ (see Simmons, J. P., Nelson, L. D., & Simonsohn, U. (2011). False-positive psychology: Undisclosed flexibility in data collection and analysis allows presenting anything as significant. Psychological science, 22(11), 1359-1366.) and the replication crisis in psychology (see Open Science Collaboration. (2015). Estimating the reproducibility of psychological science. Science, 349(6251).). It narrates a personal reflection of Katrien, a last-year psychology student, on the matter of how our philosophies shape our (scientific) world.

Start of the Lab!

Exciting times, as Kobe takes up his new position at the Brain and Cognition research unit of the KU Leuven, where he will start his own lab. For lack of a better name called “DesenderLab” now, but that might still change – suggestions welcome!

As you can see under the ‘Lab Members‘ tab, it is going to be quite crowded. Pierre Le Denmat joins the lab to work on his PhD project about how people learn to be confident (with Tom Verguts, UGent); Robin Vloeberghs joins the lab to work on his PhD project about the role of confidence in sequential decisions (with Anne Urai, ULeiden) and Gaia Corlazolli joins the lab to work on her PhD project about sharing of metacognition (with Wim Gevers, ULB). In addition, Katrien Vandenbroeck (UGent) and Hélène Van Marcke (UGent) will perform their 6 months research internship here, and Alan Voodla (UTartu, Estonia) will join 3 months as a visiting PhD student.

Finally, we drafted a lab philosophy page, reflecting the values that we wish to stand for as lab. This is supposed to be a dynamic document – so any input and suggestions are highly welcomed!
