How can system 2 be activated in dual process theory?4 answersSystem 2 can be activated in dual process theory through various interventions. One intervention is answering analytical questions before the task, which has been shown to double the likelihood of answering correctly. Another intervention is warning participants about the difficulty of the task, which has been found to improve performance significantly. Additionally, offering information about cognitive biases and the role of analytic thinking can also prime participants to use System 2. System 2 processes consist of cycles of activation and mental rehearsal of action schemata, often in inner speech, which then generate imagistic representations of action that are broadcast to System 1 mechanisms. System 2 can be malleable and influenced by instruction, imitation, and beliefs, similar to how actions and sequences of actions are malleable.
