Age differences in working memory’s relevance may stem from differing performance levels

Evidence

The age-related modulation of the strength of the correlation between WMC and SiN perception could be due to the different performance levels at which the age groups operated in this study (mean identification was 68, 60, 57, and 48 RAUs for the Young, Middle-Aged, Young-Old, and Old-Old group, respectively). — Dijk, Pim van, Physiology, Psychoacoustics and…, 1138

• QUESTION: This is offered as a possible explanation but then partially addressed by the lowest-SNR analysis showing no young correlation even at matched difficulty — the tension between the two results deserves resolution.
