  1. An Integrated Theory of the Mind

  2. 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

  3. 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.

  4. The ACT-R 5.0 Architecture

  5. 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.

  6. The Perceptual-Motor System

  7. The Goal Module • Keeping track of what these intensions are so that behavior will serve the goal.

  8. The Declarative Memory Module • Information stored in declarative memory that promotes things like long-term personal and cultural coherence.

  9. The Declarative Memory Module

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

  11. 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.

  12. Tracking multiple buffers in an fMRI study • Consequence of the integrated approach is to make us more open to additional data such as fMRI.

  13. General Discussion • The ACT-R architecture is incomplete. • Missing certain modules. • The proposal that all neural processing passes through the basal ganglia is false.
