A computational approach to modeling population differences.
Four experiments were conducted to determine whether the Hyperspace Analogue to Language (HAL) model of semantic memory could differentiate between two different populations. An analysis of the differences in densities (or average distances between word neighbors in semantic space) in HAL matrices--generated from text corpora derived from younger and older adults--confirmed that HAL was able to...
متن کاملA New Approach to Computational Turbulence Modeling
We present a new approach to Computational Fluid Dynamics CFD using adaptive stabilized Galerkin finite element methods with duality based a posteriori error control for chosen output quantities of interest. We address the basic question of computability in CFD: For a given flow, what quantity is computable to what tolerance to what cost? We focus on incompressible Newtonian flow with medium to...
متن کاملA Computational Modeling Approach to Understanding Gender Differences in the Iowa Gambling Task
Several studies have found gender differences in Iowa Gambling Task (IGT) performance in which males typically outperform females. However, the precise mechanism that underlies this effect remains unclear, and prior modeling efforts have been unable to pinpoint specific gender differences in behavioral aspects of the IGT. Our results replicated the behavioral gender difference finding and showe...
متن کاملA unified computational modeling approach to decision making
For centuries, theorists have focused almost exclusively on the use of additive utility representations in attempts to describe decision behavior. This basic framework has constantly been modified in order to account for challenging empirical results. However, each revision to the basic theory has in turn consistently been confronted with conflicting evidence. Here, we summarize an alternative ...
متن کاملA computational language approach to modeling prose recall in schizophrenia.
Many cortical disorders are associated with memory problems. In schizophrenia, verbal memory deficits are a hallmark feature. However, the exact nature of this deficit remains elusive. Modeling aspects of language features used in memory recall have the potential to provide means for measuring these verbal processes. We employ computational language approaches to assess time-varying semantic an...
