Delay Detection Thresholding Raw Data (also includes tapping data)
van Vugt & Tillmann. December 2013.
Here, we post the complete dataset associated with the following study:
van Vugt & Tillmann. Thresholds of auditory-motor coupling measured with a simple task in musicians and non-musicians: Was the sound simultaneous to the key press?
The participants are coded numerically, with a letter prefix, for example B11.
The letter prefix indicates the experimental group: N=non-musician, P=pianist, B=brass player.
The data presented here are (details can be found in the paper):
* Keystroke-sound delay detection thresholds (using the pythonMLP output format)
* Anisochrony thresholds (using the pythonMLP output format)
* Synchronisation-continuation tapping
The pythonMLP outputs are organised as follows. For each task, each participant and each block, two files are created. One file contains the metadata (FILENAME.metadata.txt) and the other file (FILENAME.txt) contains the full details of all trials in the block.
For details about how this output is created, please refer to the pythonMLP package ( https://github.com/florisvanvugt/PythonMLP ). In brief, the trial listing of each block is organised as follows:
PARTICIPANT TRIAL TYPE STIMULUS RESPONSE
B9-activeagency-2 0 mlp 600.000000 1
B9-activeagency-2 1 mlp 173.411931 1
B9-activeagency-2 2 mlp -3.890364 0
B9-activeagency-2 3 mlp 90.998540 1
B9-activeagency-2 4 mlp 48.928423 0
B9-activeagency-2 5 catch 0.000000 0
[...]
Each line corresponds to one trial.
- "PARTICIPANT" lists the participant number, a dash, the task (delay detection is referred to as "activeagency" for historical reasons), another dash, and the block number (from 1 to 3).
- "TYPE" corresponds to the trial type: catch trials (with zero stimulus level) or mlp trials (in which the stimulus level is determined by the MLP algorithm).
- "STIMULUS" lists the stimulus level (amount of delay in msec between keystroke and sound in the delay detection task; and amount of lateness of the fourth tone in the anisochrony task).
- "RESPONSE" encodes the participants' response. In the case of the delay detection, 0 stands for "immediate" and 1 stands for "delayed". In the case of the anisochrony test, 0 stands for "regular" and 1 stands for "irregular".
