Phenomenological validity of an OCD-memory model and the remember/know distinction

Area of Science:

• Cognitive Psychology
• Neuroscience
• Clinical Psychology

Background:

• Compulsive-like checking behavior in healthy individuals affects meta-memory, reducing recollection vividness and confidence.
• This experimental paradigm models obsessive-compulsive disorder (OCD) checking, suggesting checking is counterproductive for memory distrust.

Purpose of the Study:

• To investigate the phenomenological quality of memory distrust after checking behavior.
• To determine if repeated checking shifts memory retrieval from 'remembering' to 'knowing'.

Main Methods:

• Utilized interactive computer animation to simulate compulsive-like checking behavior in healthy subjects.
• Replicated previous findings on memory vividness, detail, and confidence.
• Assessed participants' endorsement of statements reflecting memory ambivalence characteristic of OCD patients.

Main Results:

• Replicated earlier findings on decreased memory vividness, detail, and confidence.
• Participants exposed to checking behavior endorsed statements expressing memory ambivalence, validating the experimental model.
• Post-checking, participants relied on 'knowing' (general memory) rather than 'remembering' (specific memory) to assess outcomes.

Conclusions:

• Repeated checking increases memory distrust, rather than alleviating it, creating a detrimental cycle.
• OCD checkers may have high standards for memory certainty, leading to distrust of episodic memory.
• Clinical issues in OCD may stem from attempting to combat memory distrust through counterproductive checking behaviors.
