- Cognitive approach & structure
- Information processing approach: aim is to specify the process & structure underlying cognitive performance
- stimulus --> attention --> perception --> thought process --> decision --> response or action
- Types of cognition
- lower order (attention, perception)
- higher order (memory, language, reasoning & problem solving)
- ACT - R: cognition arises from interaction of procedural (knowledge of how to do things) and declarivtve (facts)
- model accounts for memory, learning, spatial cognition reasoning
- A 'propositional network' respresents the meaning of a senstance
- - Links become stronger as used more, ----------------------practice is important for developing extensive semantic memory
- Limit of WM can restrict the spreading ---------------------- when many links are activated each link recieves little activation which leads to overload
- - Links become stronger as used more, ----------------------practice is important for developing extensive semantic memory
- The Parallel Distributed Processing (Connectionism):
- Attempts to incorporate the physiological and structural properties of human neurons
- Info represented as patterns of activation along neural elements
- Principles: (1)Information distributed (2)memory & knowledge stored in connections (3)learning can change connections
