Cognitive Confidence
Precuneus is activated during
retrieval of visuospatial material
More impaired in checkers;impairment caused by checking
Poor confidence a predictor of checking; may cause it
OCD characterised by lack of confidence in cognition and FOK

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
9
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)

E-prime visuospatial task
11
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
12
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
13
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
14
Conclusions
• Visuospatial deficit only found in checkers• Meta-memory deficit found across OCD• Benefits of considering OCD by dimensions
