Dual Systems Theory
The process of two separate yet interacting systems of thinking and Decision making
System 1
Automatic, Holistic, Intuitive thinking based on Heuristics
Heuristics
Types of Heuristics
- Representativeness Heuristic
Availability Heuristic
past experiences/examples that are so readily available which encourage prejudgement
Representativeness Heuristic
Assume and the individual case is more representative that is really is
System 2
Analytical, Logical, Slower Thinking
Kahneman Theory
- System 2 “background mode”, little capacity is engaged
System 1 and 2
Kahneman (2011)
System 2 Kahneman
System 1 Kahneman
Link to Schema Theory
Highly Selective perception and memory shape/govern thinking=System 1 controls System 2 choices
Link to Schema=Automatic thinking is based on previous experiences
Strengths of Theory
Neurophysiological evidence for two systems, increasing
Limitations
Questions regarding nature of the two systems and their interaction remained unanswered
-Unclear localisation of dual systems theory in the brain
