Metacognitive Processes in Radiologic Decision-Making: The Hard-Easy Effect and Temporal Thinking Dynamics.

Area of Science:

• Cognitive psychology
• Medical decision-making
• Radiology

Background:

• Effective metacognitive processes, including confidence monitoring and regulatory decisions, are crucial for accurate and efficient radiologic diagnosis.
• Identifying metacognitive pitfalls is essential for enhancing diagnostic accuracy and optimizing workflow in radiology.

Purpose of the Study:

• To investigate the hard-easy effect and temporal dynamics in radiologic decision-making.
• To compare metacognitive processes between radiologists and non-radiology medical professionals.

Main Methods:

• Radiologists and non-radiologists reviewed bone radiographs to detect lesions, rating confidence and recommending actions.
• Decisions were compared against CT/MRI-validated reference standards.
• Metacognitive analysis included success rates, confidence levels, overconfidence, response times, resolution, and control sensitivity.

Main Results:

• Radiologists demonstrated higher success (73.59%) and confidence (85.12%) than non-radiologists (64.71% and 81.24%, respectively).
• Overconfidence was prevalent (14.73%) but lower in radiologists (11.52%) than non-radiologists (16.52%).
• A hard-easy effect was observed, with overconfidence increasing in difficult cases; faster decisions were more accurate.

Conclusions:

• Radiologic expertise improves diagnostic success and confidence monitoring, yet both experts and non-experts remain susceptible to overconfidence.
• The hard-easy effect and detrimental temporal dynamics (prolonged deliberation) impact decision-making accuracy in radiology.
• Addressing metacognitive biases is key to improving radiologic diagnostic performance.
