False Memory and Obsessive-Compulsive Disorder (OCD)
False Memory Susceptibility in OCD
Reduced Proneness to False Memories
Research indicates that individuals with obsessive-compulsive disorder (OCD) are less prone to false memories compared to healthy controls. In a study using the Deese-Roediger-McDermott (DRM) false memory paradigm, both checker and non-checker OCD groups demonstrated similar correct recall and recognition performance as healthy controls but exhibited a lower tendency to recall or recognize non-presented information as true. This reduced susceptibility to false memories in OCD may be attributed to their reliance on item-based rather than relational processing during encoding.
Memory Confidence in OCD
Under-Confidence in Memory and Perception
People with OCD often exhibit lower confidence in their memory and perception abilities. A comprehensive review and meta-analysis found that individuals with OCD not only perform worse on cognitive tasks but also report significantly lower confidence in their performance compared to non-clinical controls. This under-confidence is more pronounced than the actual performance deficits, suggesting a genuine lack of trust in their cognitive processes.
Impact of Repeated Checking on Memory Confidence
Repeated checking, a common behavior in OCD, paradoxically reduces confidence in memory. Studies have shown that while repeated checking does not necessarily impair memory accuracy, it does lead to decreased vividness and detail in recollections, thereby undermining memory confidence . This phenomenon is particularly evident in individuals with primary checking compulsions, who report progressively lower confidence in their long-term memory for threat-related stimuli over repeated trials.
Cognitive Distrust Beyond Memory
Distrust in Attention and Perception
The distrust in cognitive processes among individuals with OCD extends beyond memory to include attention and perception. Research has demonstrated that OCD patients show less confidence in their attention and perception abilities compared to both clinical and non-clinical control groups. This distrust is uniquely related to checking behaviors, with repeated checking exacerbating the lack of confidence in attention.
Phenomenological Aspects of Memory Distrust
Vividness and Detail in Recollections
The phenomenological quality of memory in OCD is characterized by less vivid and detailed recollections. Experimental models simulating compulsive checking behaviors have shown that as checking continues, individuals experience their memories as less vivid and detailed, which further undermines their confidence in these memories. This shift from specific "remembering" to general "knowing" about the outcomes of checking highlights the ambivalence and uncertainty that OCD patients feel about their memory.
Conclusion
In summary, individuals with OCD are less prone to false memories but suffer from significant under-confidence in their memory, attention, and perception. Repeated checking behaviors, while intended to alleviate doubt, paradoxically reduce memory confidence and contribute to a cycle of distrust in cognitive processes. Understanding these dynamics is crucial for developing effective interventions to address the cognitive and metacognitive challenges faced by individuals with OCD.
