Speaker information

Mariano Sigman was born in Argentina and grew up in Barcelona, Spain. He obtained a master degree in physics at the University of Buenos Aires and a PhD in neuroscience at the Rockefeller University, with Charles Gilbert, investigating how the cortex organizes to assemble the statistics of the visual world, vast cultural changes (such as reading) and dynamically multiplex several functions through addressing mechanisms and top-down control. He moved to Paris as a Human Frontiers Fellow, investigating with Stanislas Dehaene decision making, cognitive architecture and consciousness.

Mariano Sigman : The construction of confidence

Thursday, 10 September, 2015 - 11:30 to 13:00

In this lecture we will explore the construction of confidence, mostly in simple perceptual decisions. I will discuss how and why confidence varies across different individuals.  Why judges make systematic and reliable errors - being often overconfident without sufficient evidence and under-confident when there is ample evidence. I will present how current experimental evidence constrains the mechanisms by which models of decision making compute confidence.
