Background:

• Information accessibility from retrieval practice can negatively impact analogical reasoning.
• Understanding the neural mechanisms of inhibitory control during selective information retrieval is crucial.

Purpose of the Study:

• To investigate the neural signatures of inhibitory control during selective retrieval.
• To examine how selective retrieval affects subsequent analogical reasoning performance.
• To explore the electrophysiological correlates of memory downregulation during analogical thinking.

Main Methods:

• Employed electrophysiological measures (event-related potentials - ERPs) to record brain activity.
• Utilized a selective retrieval task followed by an analogical reasoning test.
• Analyzed behavioral performance and ERP components (e.g., FN400 effect) during retrieval and analogy phases.

Main Results:

• Selective retrieval impaired performance on the analogical reasoning task.
• Decreased FN400 amplitudes during retrieval correlated with analogical reasoning deficits, suggesting reduced interference.
• Differential ERP modulations during the analogy retrieval phase indicated successful downregulation of inhibited solutions.

Conclusions:

• Inhibitory control during selective retrieval downregulates competing memory representations.
• These neural mechanisms are critical for effective analogical reasoning.
• Findings advance the understanding of the neural basis of analogical thinking and memory control.
