Metacognitive training facilitates optimal cognitive offloading

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human-Computer Interaction

Background:

• Cognitive offloading utilizes external tools to reduce mental effort, crucial for daily functioning.
• Biases in offloading strategies are linked to inaccurate self-assessments of cognitive abilities.
• Metacognitive interventions show potential but yield inconsistent results in mitigating these biases.

Purpose of the Study:

• To investigate the impact of a brief metacognitive intervention on cognitive offloading strategies.
• To determine if metacognitive predictions and feedback can optimize the use of external reminders.

Main Methods:

• A short metacognitive intervention (5 trials) involving prediction and feedback was administered.
• Participants engaged in a memory task, choosing between internal memory and external reminders for varying rewards.
• Two experiments (N=164 and N=416) assessed the effectiveness of the intervention and its components.

Main Results:

• The intervention significantly improved metacognitive calibration and led to more optimal reminder-setting strategies.
• Combining metacognitive prediction with feedback was crucial; predictions alone did not improve strategies.
• Replication in a larger sample confirmed the efficacy of the combined intervention.

Conclusions:

• A brief metacognitive intervention pairing prediction with feedback can optimize cognitive offloading.
• This approach enhances decision-making regarding the use of internal memory versus external aids.
• Findings suggest a practical method to improve cognitive efficiency in everyday tasks.
