Alternatively, confidence is framed in mathematics as an objective statistical quantity: the probability that a chosen hypothesis is correct. Despite similar terminology, it remains unclear whether the subjective feeling of confidence is related to the objective, statistical computation of confidence. To address this, we collected confidence reports from humans performing perceptual and knowledge-based psychometric decision tasks. We observed two counterintuitive patterns relating confidence to choice and evidence: apparent overconfidence in choices based on uninformative evidence, and decreasing confidence with increasing evidence strength for erroneous choices. We show that these patterns lawfully arise from statistical confidence, and therefore occur even for perfectly calibrated confidence measures. Furthermore, statistical confidence quantitatively accounted for human confidence in our tasks without necessitating heuristic operations. Accordingly, we suggest that the human feeling of confidence originates from a mental computation of statistical confidence.

[Koglist] [CEU Cogsci Talks] CogSci CEU Departmental Colloquium: November 30, Wednesday: David Pietraszewski: Towards a mechanistic account of the psychology of groups: Basic theoretical models and empirical tests of the psychology underlying racial categorizat

by Gyorgyne Finta

REMINDER: The CEU Department of Cognitive Science cordially invites you to its talk as part of the Departmental Colloquium series by David Pietraszewski<https://www.mpib-berlin.mpg.de/en/staff/david-pietraszewski>, Max-Planck Institute Host: Christophe Heintz When: November 30, Wednesday, at 5 pm in Oktober 6 street 7, 1st floor, room 101. Title: Towards a mechanistic account of the psychology of groups: Basic theoretical models and empirical tests of the psychology underlying racial categorization. Abstract: The cognitive revolution can be understood as a commitment to describing psychological processes as mechanistically as possible, without intervention from an intentional agent or homunculus. This talk presents an overview of a research program committed to describing the psychology of groups in this way. Two primary veins of research will be described: First, a body of work will be presented that suggests we may have discovered the function of the cognitive mechanisms responsible for producing the phenomenon of racial categorization. Second, a task analysis will be presented that describes the invariances of n-person conflict and suggests a way to define the construct "group" in purely mechanistic terms.

[Koglist] PhD studentships in Cognitive Science at CEU, Budapest

by Gergely Csibra

Applications are invited for PhD studentships at the Department of Cognitive Science at Central European University (CEU), Budapest, Hungary. This is a research-based training program in human cognition with social cognition and learning as core themes. Research topics include cooperation, communication, social learning, cultural transmission, embodied cognition, joint action, cognitive development, strategic decision-making, problem solving, visual cognition, sensory and statistical learning, visual psychophysics, computational neuroscience, and social cognitive neuroscience. Students will follow courses in cognitive psychology, philosophy of mind, cognitive anthropology, and computational cognition, and will receive practical research training in the laboratories of the members of the department. Faculty includes Gergely CSIBRA (cognitive development, cognitive neuroscience) József FISER (visual perception and cognition, biological and statistical learning) György GERGELY (infant cognition, developmental psychopathology) Christophe HEINTZ (culture and cognition, scientific cognition, behavioral economics) Günther KNOBLICH (embodied and social cognition, problem solving) Ágnes M. KOVÁCS (development of social cognition, theory of mind, mental representations) Máté LENGYEL (computational neuroscience, learning and memory) Natalie SEBANZ (social cognition, social cognitive neuroscience) Dan SPERBER (culture and cognition, communication and language, evolution) Ernő TÉGLÁS (cognitive development, reasoning) Applicants are expected to hold an internationally recognized Master’s or comparable degree in the standard disciplines that constitute cognitive science. A comparable degree in other Social Sciences, Humanities, or other disciplines will also be considered in case of an excellent academic record. We will consider the applications of *exceptional* students who only hold a Bachelor degree, provided it is in a discipline closely associated to cognitive science. Application deadline: February 1, 2017. For further details see http://cognitivescience.ceu.hu/Admission ---- CEU (www.ceu.hu) is a graduate research-intensive university located in Budapest, Hungary and accredited in the United States and Hungary. CEU enrolls more than 1400 graduate students from more than 100 countries in its master's and doctoral programs. The teaching staff consists of more than 189 resident faculty from 29 countries, and prominent visiting scholars from around the world. The language of instruction is English.
