[Koglist] Invitation: T. Papadopoulos: PA and RAN - Elucidating their relationship with word reading

by Dénes Tóth

Dear Colleagues, The Neurocognitive Development Research Group cordially invites you to the following talk:* * *Timothy C. Papadopoulos *(University of Cyprus)*: PA and RAN: Elucidating their relationship with word reading* Location: MTA TTK, ground floor, lecture room 2 Date: *December 7 (Wednesday), 2016, 14.00-15.30 * Abstract: Phonological awareness (PA) and rapid automatized naming (RAN) have been shown to be reliable predictors of reading in several alphabetic and nonalphabetic languages, accounting for unique variance above and beyond general cognitive ability, short-term memory or letter knowledge. However, until recently little was known about the nature and conceptualization of these skills and the reasons why PA and RAN are related to word reading, an uncertainty that emanated from both PA’s and RAN’s multi-componential nature. This lecture focuses on the longitudinal evaluation of theory-driven conceptualizations of PA and RAN in a sufficiently transparent orthography (Greek) in two different cohorts of young readers, using advanced techniques within SEM. It also reports findings from studies aiming to understand the RAN-reading relationship based on the partition of RAN total time into its constituent components (articulation and pause time). Theoretical and practical implications of these findings are discussed. Everyone is welcome to attend. Kind regards, Denes Toth --- Dénes Tóth, PhD Brain Imaging Centre, Research Centre for Natural Sciences, Hungarian Academy of Sciences e-mail: toth.denes(a)ttk.mta.hu

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.
