Cell Assembly-based Task Analysis (CAbTA) Dan Diaper and Chris Huyck Abstract: Based on an Artificial Neural Network model, Cell Assembly-based Task Analysis is a new method that outputs a task performance model composed of integrated mind-brain Cell Assemblies, which are currently believed to be the most plausible, general organisation of the brain and how it supports mental operations. A simplified model of Cell Assemblies and their cognitive architecture is described and then used in the method. A brief sub-task is analysed. The method's utility to research in Artificial Intelligence, neuroscience and cognitive psychology is discussed and the possibility of a General Theory suggested. Key Words: Ergonomics, Cognitive Psychology, Artificial Intelligence, Neuroscience, Task Analysis, Human-centred Computing, Artificial Neural Networks, Cell Assemblies. Some of the work presented here is further explained in an arXiv paper entitled The Task Analysis Cell Assembly Perspective.
