Fig. 4. Relationships between anxiety ratings and representational similarity (ROI approach).
A Correlations of Hamilton Anxiety Rating Scale (HAM-A) values and the Representational Similarity Analysis (RSA) metrics for the anxiety and neutral run. B Correlations of the self-reported anxiety ratings (Likert Scale: 0–10) obtained directly after the scan and the RSA metrics for the anxiety and neutral run. All RSA values on the x-axis were square-root transformed to account for skewness and kurtosis. Asterisk indicates significant result (p < 0.05), while colors indicate control subjects as well as medicated and unmedicated patients.
