Approximate Analysis by Synthesis: Towards a Computational Theory of Vision ABSTRACT: Vision is humans' underappreciated superpower. It gives us the miraculous ability to perceive the three-dimensional structure of the world from the complex pattern of light rays which are imaged on our retinas. Vision can be conceptualized as Analysis by Synthesis, formalized by Bayesian probability […]
Acquiring syntactic variation: regularization in wh-question production. ABSTRACT: Children are often exposed to language-internal variation. Studying the acquisition of variation allows us to understand more about children’s ability to acquire probabilistic input, their preferences at choice points, and factors contributing to such preference. Using wh-variation as a case study, this dissertation explores the acquisition of […]
Canonical dimensions of vision. For department members, department major/minor undergraduate students, and invited guests. In-person and on Zoom.
Selection in Written Language Production: Evidence from Aphasia ABSTRACT: Most models of word production assume that in the process of producing a target word, multiple distractors also get activated, both other words (at the lexical level) and other phonemes/letters (at the segmental level). Thus, a selection mechanism is needed to select the targets at each […]
Development of relational reasoning: When do children pass the Relational Match-to-Sample task? ABSTRACT: Relational ability—the ability to compare situations or ideas and discover common relations – is a key process in higher-order cognition that underlies transfer in learning and creative problem solving. For this reason, it has generated intense interest both among developmentalists and in […]
