[koglist] [CEU Cogsci Talks] Reminder: Michael Ramscar, Tomoreow, THURSDAY, September 19, 5PM CDC at Hattyúhaz

by Gergely Csibra

Michael Ramscar (Tübingen University) Date: Note that exceptionally the talk will take place on THURSDAY, September 19, 2013, 5 PM Location: Cognitive Development Center, Hattyú u. 14, 3rd floor Title: Nonlinear dynamics of lifelong learning As adults age, their reaction times slow across a range of psychometric tests. This has been widely taken to show that cognitive information-processing capacities decline over the course of adulthood. I will show that these response patterns, which are typically taken as evidence for (and measures of) declining cognitive-processing capacities, arise naturally out of basic principles of learning. These basic, formal learning principles both correctly identify the pattern of performance exhibited by very young children in word learning tasks (which can differ greatly from that of young adults) as well successfully predicting that older adults will exhibit far greater sensitivity to fine-grained properties of test stimuli than younger adults. Taken together, the findings I present show that the patterns of change observed in cognitive performance across the lifespan simply reflect the consequences of learning from the kind of statistical distributions that typify human experience. Once the information-processing loads are inevitably imposed by learning from this experience are controlled for, it appears that the performance changes that are usual taken as evidence of innate abilities in infants, or declining cognitive capacities in older adults, support little more than the unsurprising idea that the way individuals choose between or recalls items will be affected by the number of items there are and what an individual has already learned about them. I will consider the implications of this for our scientific and cultural understanding of lifelong cognitive development. PLEASE NOTE: Our seminar room has a limited capacity. Please arrive early to ensure you get a seat. The talk will begin promptly at 5.
