Dual-Process Theory

The framework describing two distinct modes of cognitive processing: fast, automatic, intuitive operations (System 1) and slow, deliberate, analytical operations (System 2).

Levels of Analysis

Neural: limbic system, basal ganglia, prefrontal cortex
Cognitive: intuitive heuristics vs. controlled reasoning, automaticity vs. deliberation
Behavioral: rapid judgments, reflective evaluation, conflict monitoring

Inputs

• sensory cues
• prior knowledge
• task demands
• time pressure
• motivational states

Outputs

• fast heuristic judgments
• slow analytical conclusions
• conflict detection between systems
• revised or overridden initial responses

Example

A person instantly assumes a job candidate is competent based on first impressions (System 1), but later reevaluates their judgment after reviewing detailed performance data (System 2).
