Overview of age differences in attentiona
| Task | N (YA/OA) | Performance YA (z ± SEM) | Performance OA (z ± SEM) | z | p |
|---|---|---|---|---|---|
| DLTb | 77 (39/38) | 0.415 (0.200) | −0.425 (0.048) | 3.790 | <0.001 |
| D2 | 77 (39/38) | 0.634 (0.133) | −0.651 (0.113) | 6.109 | <0.001 |
| DSST | 77 (39/38) | 0.629 (0.129) | −0.645 (0.120) | 5.689 | <0.001 |
| DST | 77 (39/38) | 0.206 (0.153) | −0.212 (0.164) | 2.066 | 0.039 |
aFor each age group, for all cognitive tasks, mean performance is provided as z value ± SEM. DLT, Dichotic Listening Task; D2, D2 test of attention. All comparisons are evaluated using nonparametric Mann–Whitney U tests (YA vs OA).
bThe difference between LIs for the FL and FR condition was calculated to provide an overall measure of participants' auditory-selective attention ability.
