Hypotheses

1. negative correlation between visuospatial accuracy and checking scores

2. positive correlation between trait cognitive confidence scores and checking scores

3. negative correlation between FOK judgements and checking scores.

Method

• Ethics• Correlation design• Sample• Materials: questionnaire; computerised trials

Page 9: Presentation to BPS Wessex Student Conference 10th May 2014

Questionnaire

• Existing self-report measures

– Obsessive-Compulsive Inventory – Revised (OCI-R)

– Meta-cognition Questionnaire (MCQ) (cognitive confidence subscale only)

– Beck Depression Inventory (BDI)

– State Trait Anxiety Inventory (trait subscale only) (STAI-T)

Results (1): visuospatial memory

• Checking and accuracy – sig negative correlations at both loads – rho = -.31 for both, p=.014 (high) and p=.015 (low).

• Median split showed sig effect of checkingNegative correlation between visuospatial accuracy and

checking scores

Results (2): meta-memory

• Checking and meta-memory– sig correlation (rho=.35, p=.005)

• Meta-memory also showed sig correlations with– Overall OCD– Washing, hoarding and neutralising– Depression/anxiety symptoms

positive correlation between trait cognitive confidence scores and checking scores

Results (3): feeling of knowing (FOK)

• No significant association found• However, FOK and accuracy found to correlate only

for non/low-checking group (right scatterplot) checkers non/low-checkersnegative correlation between FOK judgements and

checking scores

Conclusions

• Visuospatial deficit only found in checkers• Meta-memory deficit found across OCD• Benefits of considering OCD by dimensions
