A Capacity Limited, Cognitive Constructionist Model of Virtual Presence By David Nunez
eBook (PDF): $0.00
The Capacity Limited, Cognitive Constructionist (CLCC) model of presence is proposed as an information processing model of presence, and is shown to have more theoretical power than extant models of... More > presence. The CLCC model defines information processing paths between attention, working memory, declarative memory and procedural memory, which operate to create and maintain a semantic context or bias. Bottom-up information entering the sensory cortices is filtered by attention into working memory where it forms temporary structures encoding the subject’s experience of the VE. These temporary structures are also contributed to by top-down information, which arises from active knowledge clusters in declarative memory. This interaction of top-down and bottom-up data gives the entire model a semantic bias which attempts to keep the subject’s construction of the environment semantically coherent.< Less
A Connectionist Explanation of Presence in Virtual Environments By David Nunez
eBook (PDF): $0.00
Presence can be understood as the sensation that a virtual environment is a real place, that the user is actually in the virtual environment rather than at the display terminal, or that the medium... More > used to display the environment has disappeared leaving the environment itself. We present an attempt to unite various presence approaches by reducing each to a common basis (behavior selection and control) and re-conceptualizing presence in these terms by defining cognitive presence – the mental state where the VE rather than the real environment is acting as the basis for behavior selection. The thesis presents the construction of a three-layer connectionist model to explain and predict cognitive presence. This model takes input from two major sources: the perceptual modalities of the user, and the mental state of the user. These two basic sources of input competitively spread activation to a central layer which competitively determines which behavior script will be applied to regulate behavior.< Less
