Table 2.

Tasks and dependent variables included in each principal component analysis. Sensitivity refers to the d′ measurement. Note that the paced tapping to metronome, paced tapping to music, and synchronization-continuation also require perception abilities. Duration is approximate and includes instructions. For trials that were completed twice (Anisochrony detection and all tapping tasks), the duration should be doubled to include the repetition
