The Curious U: Integrating Theories Linking Knowledge and Information-Seeking Behavior.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Behavioral Science

Background:

• Empirical studies consistently show an inverted-U relationship between knowledge and curiosity.
• Existing theoretical accounts for this phenomenon lack a clear, integrated link.
• The 'sweet spot' for curiosity lies between complete unfamiliarity and excessive familiarity.

Purpose of the Study:

• To review and integrate seven psychological theories explaining the knowledge-curiosity inverted-U relationship.
• To propose a coherent framework that unifies these diverse theoretical accounts.
• To elucidate the role of learning progress maximization in driving curiosity.

Main Methods:

• Systematic review of seven prominent psychological theories on curiosity.
• Development of an integrative framework based on normative and process theories of curiosity.
• Analysis of how existing theories align with the proposed framework's principles.

Main Results:

• The inverted-U relationship emerges from the fundamental drive to maximize knowledge and learning progress.
• Normative theories explicitly define knowledge maximization as the objective.
• Process theories highlight mechanisms that signal incomplete knowledge, thereby facilitating learning.

Conclusions:

• The proposed framework integrates diverse curiosity theories by centering on learning progress maximization.
• Process-theoretic mechanisms can be understood as signaling opportunities for optimal learning.
• This integrated perspective offers implications for future research on curiosity and related cognitive phenomena.
