Cognitive Science Colloquium - Thurs, April 14 (Genetics & Generalization)


Speaker: Dr. Sarah-Jane Leslie (Philosophy, Princeton)
Time/Place:  Thursday, April 14th  - 3:30-5:30 pm in Bio-Psych 1208.
Title: Generics and Generalization

Abstract: Generics are sentences such as "tigers are striped" and "ravens are black". They are truth-conditionally complex: e.g. "ducks lay eggs" is judged true while "ducks are female" is rejected as false, despite the fact that only female ducks lay eggs. Similarly, "mosquitoes carry malaria" is accepted but "books are paperbacks" is rejected, yet over 80% books are paperbacks, while less than 1% of mosquitoes carry malaria. Despite their seeming complexity, I argue that generics give voice to cognitively primitive generalizations, while quantified statements give voice to more cognitively sophisticated and taxing ones. Further, the puzzling truth-conditional behavior of generics can be explained by an empirically plausible characterization of these primitive generalizations. I present recent experimental evidence in support of these hypotheses.
