ACT-R: A higher-level account of processing capacity

  • John R. Anderson (a1), Christian Lebiere (a1), Marsha Lovett (a1) and Lynne Reder (a1)
Abstract

We present an account of processing capacity in the ACT-R theory. At the symbolic level, the number of chunks in the current goal provides a measure of relational complexity. At the subsymbolic level, limits on spreading activation, measured by the attentional parameter W, provide a theory of processing capacity, which has been applied to performance, learning, and individual differences data.
