Toward A Multilevel Analysis of Human Attentional Networks
نویسندگان
چکیده
Attention is a complex multilevel system subserved by at least three interacting attentional networks in the brain. This paper describes a multilevel computational model of attentional networks, developed in both the symbolic architecture of ACT-R and the connectionist framework of leabra. We evaluated the model using the Attentional Networks Test and the simulation results fitted the empirical data well. We argue that developing multilevel computational models helps to link findings at different levels.

Background: Despite the implementation of harm reduction program, some injecting drug users (IDU) continue to engage in high-risk behaviors. It seems that there are some social factors that contribute to risk of human immunodeficiency virus (HIV) transmission in IDUs. The aim of this study was to analysis the social network of IDUs and examines the effect of network location on HIV transmission...

This study was performed to examine the effect of holistic face processing and trait anxiety on children’s attentional biases toward schematic natural and jumbled emotional faces (angry, happy, neutral). The participants were entered into study considering their scores in Trait anxiety inventory for children (Spielberger, 1973) and the results of a semi-structured interview. 30 high-and 30 low ...
متن کاملA symbolic model of human attentional networks
An increasing body of evidence has shown that attention is a multi-type and multilevel cognitive faculty. The dominant computational modeling approaches to attention have often focused on one specific type of attention at one specific level. In particular, various connectionist modeling techniques at the subsymbolic level have been widely adopted. In this paper, we report a symbolic computation...
