Introduction

ACT-R has• Consists of multiple modules.

• The perceptual-motor module• The goal module• The declarative memory module• Associated with distinct regions.

• Integration of cognition

• Subsymbolic process

Newell - Soar system

Introduction

Goal – Describe how cognition is integrated in the ACT-R theory.

Newell – A single system (mind) produces all aspects of behavior.

Develops two advantages• Capable of attacking real-world problem.• Capable of integration the mass of data from cognitive

neuroscience methods like brain imaging.

The ACT-R 5.0 Architecture

The Perceptual-Motor System

EPIC architecture – Successful strategy for relating cognition to perception and action.

ACT-R visual system• Visual-location module• Visual-object module

Similar to preattentive visual processing.

For the fixed-time approximation, this parameter is set at 185ms in ACT-R.

The Perceptual-Motor System

The Goal Module

Keeping track of what these intensions are so that behavior will serve the goal.

The Declarative Memory Module

Information stored in declarative memory that promotes things like long-term personal and cultural coherence.

The Declarative Memory Module

Procedural Memory

P will shift from θ to m / (m+n) at a speed controlled by V.

The effect of instruction and practice in a dynamic task.

• With respect to applications of architectures to understanding the details of human performance in tasks like the AAWC task.

Tracking multiple buffers in an fMRI study

• Consequence of the integrated approach is to make us more open to additional data such as fMRI.

General Discussion

The ACT-R architecture is incomplete.• Missing certain modules.• The proposal that all neural processing passes through the

basal ganglia is false.
