Motor performance and speeded response tasks¶
Movement itself is the object: timing, sequencing, adaptation or speed of a well-specified response; tapping rate, error, completion time and dual-task cost are the measures.
This family contains 5 tasks.
Digit Symbol Substitution¶
Timed paper-and-pencil or computerized task: substitute digits for symbols (or vice versa) using a visible key; items completed in a fixed interval index processing speed. Engages 5 processes.
Finger Tapping¶
Repetitive single-finger or sequence tapping at fastest or paced rates; taps-per-interval and tap-timing variability index motor speed and rhythm control. Engages 4 processes.
Mirror Tracing¶
Tracing of a figure viewed only in a mirror; error and completion time across trials index visuomotor adaptation and procedural learning. Engages 5 processes.
Motor Sequence Learning¶
Repeated execution of a fixed finger sequence; within- and across-session speed and accuracy changes index motor skill learning. Engages 5 processes.
Psychological Refractory Period¶
Two tasks presented with a short SOA; RT for the second task lengthens as SOA shortens, indexing a central response-selection bottleneck. Engages 4 processes.
Marked for review¶
The filing of these tasks is a judgement call; the note says why they are here and where else they could go.

Speeded symbol coding; processing speed rather than motor control is the usual reading |

Dual-task response-selection bottleneck; no dual-task family exists yet |
