∗refer to significant findings: p < 0.05. 1Educational level refers to the Verhaege classification (range 1–7) of the Dutch education system. The lowest score corresponds to less than 6 years of education (unfinished elementary school), while the highest score (7) represents a university master degree (at least 18 years of education). 2Non-parametric testing. 15WT-total score is the total number of words recalled over sessions 1–5 of the Dutch 15 words test. 15WT-total T-score refers to an age and education adjusted standardized score of the 15WT-total score. 30 min Recall is the number of words recalled after thirty minutes, and 30 min Recall T-score refers to an age and education adjusted standardized score of this measure (Van der Elst et al., 2005). Week Recall is the: number of words recalled after 1 week. 30 min Recognition is the number of correctly identified words out of al list 30 words (15 targets + 15 distracters). Week Recognition is the number of correctly identified words out of al list 30 (15 targets + 15 distracters). % loss recall is the percentage of the 30 min Recall that was forgotten after a 1-week period. % loss recognition is the percentage of the 30 min Recognition that was forgotten over an 1-week period MMQ-contentment, MMQ- ability and MMQ-strategy refer to the mean scores of the three subscales of the multifactorial memory questionnaire.
