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 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.

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.
