- Protocol
- EEG brain activation imaging; emotional decision-making state model
Key findings
- Proposes 16 response states built from left/right activation at two stages of processing
- Transition probabilities between states are suggested as a way to profile an individual's tendencies
- Potential clinical and counselling applications are introduced but not tested
The second part of the review builds on the methods in Part 1 to propose a working model of emotional decision making that ties brain activation to subjective experience. The model treats responses as a state machine with 16 possible states, arranged as a 4 × 4 grid crossing left versus right activation with an initial sensory response and a later perceptual or comprehension response. How likely a person is to move between these states can be used to describe their typical response style, and the authors discuss possible uses in psychiatry, psychology and counselling. This is a theoretical model rather than a test of outcomes.
