Correlation plots between loadings of the identified components and the scores. (A)(B) Correlation between loadings and digit backward [DB] scores (A) and digit forward [DF] scores (B); the higher loadings corresponded to better working memory performance. The results indicated that all the three modalities were significantly associated with DB scores. (C) Correlation between loadings and PANSS negative scores; the higher loadings corresponded to lower PANSS scores (less severe).
