Abstract
This dissertation formalizes and refines a new theory of ensemble coding: the Non-Selective Transfer Model. Within this theory, ensemble codes and subsequent summary judgments are the result of representations constructed over a subset of information that is encoded into working memory. The work begins with a brief review of current ideas present within the ensemble coding literature, followed by a set of formalized descriptions of ensemble coding theories that have been proposed. A discussion of relevant theories present in the working memory literature is also provided to motivate the structure of the subsequent model. The Non-Selective Transfer Model 2 is then systematically described at each of its core structures to provide as much clarity as possible on the generation of ensemble codes. The new model is then applied to a small selection of tasks/results present within the ensemble coding literature. This new model acts as a synthesis between ideas present within the ensemble coding literature and those of the working memory literature. The goal is to not only describe data, but to provide clarity on a theory of interacting processes that are involved in the construction of summary representations.
