Cognitive Science

Overview:This lecture series is part of PSYC3211, and covers a range of topics in computational modelling of higher order cognition.

Lecture 1: Connectionism

Associative learning via the Rescorla-Wagner rule. Connection to other error driven learning rules. Using networks as classifiers. More complex networks and pattern matching.

Lecture 2: Statistical learning

Introduction to Bayesian reasoning. A model for judging coincidences. Comments on conservative belief upating. A model of the perceptual magnet effect. Bayesian program induction for concept learning.

Lecture 3: Semantic networks

Semantic priming and spreading activation. The small world of words project. Local network structure. Predicting remote associations. Structure of semantic networks. Developmental trajectory

Lecture 4: The wisdom of crowds

Galton's vox populi. Surowiecki's criteria. Wisdom of crowds for ranking data. Example from category learning. Wisdom of crowds in combinatorial optimisation problems. Compensating for strategic behaviour. Application in forensic science

Lecture 5: Cultural transmission

The iterated learning paradigm. Theoretical argument that it reveals inductive biases. Illustration with function learning task. Limitations when individual differences exist. Cumulative cultural evolution in a language game.

Lecture 6: Summary
