"Switching" between fast and slow processes is just reward-based branching

Area of Science:

• Cognitive Science
• Decision-Making Science
• Behavioral Economics

Background:

• Goal-directed behavior often involves trade-offs between speed and accuracy.
• Heuristics, habits, and instincts are common cognitive shortcuts.
• Understanding the selection criteria for these shortcuts is crucial for explaining choice behavior.

Purpose of the Study:

• To investigate the role of reward history in selecting cognitive shortcuts.
• To determine if distinct categories of shortcuts exist or if they represent a continuum.
• To analyze the relationship between shortcut speed and deliberation speed.

Main Methods:

• The study likely involved computational modeling or behavioral experiments analyzing choice data.
• Reward history and failure rates were probably key variables tracked.
• Analysis focused on the speed of various goal-attainment strategies.

Main Results:

• Selection of shortcuts (heuristics, habits, instincts) is significantly influenced by reward history.
• Faster goal attainment and punishment for failure shape shortcut preference.
• The speeds of shortcuts and deliberate choices exist on a continuum with no clear separation.

Conclusions:

• Cognitive shortcuts are not discrete categories but exist on a spectrum of speed.
• Reward history is a unifying factor in the selection of diverse goal-seeking strategies.
• The distinction between intuitive and deliberate processing may be less clear than previously thought.
