Convergence-Divergence with Extended Practice: Three Applications

Abstract

When a task is practiced, its correlation with an external measure may increase, decrease, or remain the same, to take only linear possibilities into account. If the correlation increases, the task is said to converge on the external measure; if it decreases, the task diverges from the external measure. This simple notion has many applications, some of them entailing important theoretical consequences. The present paper discusses three of these applications.
