Continuity and discontinuity in learning
Continuity and discontinuity in learning refer to the problem of whether there are qualitative changes in the fundamental mechanisms that govern learning. This question has been examined in the literature in two separate but related ways. The first approach examines whether qualitative breaks occur with increasing expertise or additional learning, and was conducted mostly prior to the 1980s usi...
متن کاملContinuity and Discontinuity in Lambda Calculus
This paper studies continuity of the normal form and the context operators as functions in the infinitary lambda calculus. We consider the Scott topology on the cpo of the finite and infinite terms with the prefix relation. We prove that the only continuous parametric trees are Böhm and Lévy–Longo trees. We also prove a general statement: if the normal form function is continuous then so is the...
متن کاملHuman and animal cognition: continuity and discontinuity.
Microscopic study of the human brain has revealed neural structures, enhanced wiring, and forms of connectivity among nerve cells not found in any animal, challenging the view that the human brain is simply an enlarged chimpanzee brain. On the other hand, cognitive studies have found animals to have abilities once thought unique to the human. This suggests a disparity between brain and mind. Th...
متن کاملMechanisms of comorbidity, continuity, and discontinuity in anxiety-related disorders.
We discuss comorbidity, continuity, and discontinuity of anxiety-related disorders from the perspective of a two-dimensional neuropsychology of fear (threat avoidance) and anxiety (threat approach). Pharmacological dissection of the "neurotic" disorders justifies both a categorical division between fear and anxiety and a subdivision of each mapped to a hierarchy of neural modules that process d...
متن کاملNonperturbative Continuity in Graviton Mass versus Perturbative Discontinuity
We address the question whether a graviton could have a small nonzero mass. The issue is subtle for two reasons: there is a discontinuity in the mass in the lowest tree-level approximation, and, moreover, the nonlinear four-dimensional theory of a massive graviton is not defined unambiguously. First, we reiterate the old argument that for the vanishing graviton mass the lowest tree-level approx...
