Models 1 and 2: if both the hippocampal volumes and visual ratings emerged as significant univariate predictors for the same measure, two alternate memory models were defined for the memory measure. | ||||||
Empty cells, non-significant multivariate contribution; *non-significant univariate contribution; †variable not entered into model because of overlap with another predictor. | ||||||
