Individuals with high obsessive-compulsive (OC) tendencies rely more on external learning aids when their understanding is not confirmed. This reliance on proxies for internal states, like comprehension, was observed in a study on the Seeking Proxies for Internal States (SPIS) model.
Area of Science:
- Psychology
- Cognitive Science
- Clinical Psychology
Background:
- The Seeking Proxies for Internal States (SPIS) model suggests individuals with obsessive-compulsive disorder (OCD) use external cues due to limited access to internal states.
- This model's application to the feeling of understanding in OCD has not been previously explored.
Purpose of the Study:
- To investigate whether the SPIS model extends to the domain of understanding.
- To examine the relationship between OC tendencies, feedback on comprehension, and the use of external proxies.
Main Methods:
- 148 participants completed a text comprehension task with varying feedback conditions (ongoing vs. end-of-task).
- External 'learning aids' were offered as proxies.
- Participants were categorized into high and low OC tendency groups based on symptom severity.
Main Results:
- Lack of immediate feedback on understanding led to increased use of proxies.
- Participants with high OC tendencies used more proxies than those with low OC tendencies when feedback was absent.
- Obsessive-compulsive tendencies did not correlate with actual text comprehension scores.
Conclusions:
- Findings support the extension of the SPIS model to the domain of understanding.
- The results suggest that individuals with higher OC tendencies may use external proxies to gauge their understanding, particularly when internal feedback is limited.
- The study highlights potential clinical implications for understanding and treating OCD-related difficulties with self-assessment of understanding.

The mean is one such measure, calculated by totaling all values in a dataset and dividing by the number of values. For instance, the mean blood pressure reading (120, 130, 140, 150) would be 135. However, the mean can be affected by extreme values or outliers.
