Holcombe,White,Linares VSS 2008 poster on this topic, data below is subset i think
Method
-Screens:
Radius experiment: 800x600 at 160 Hz (Mitsubishi)
The rest of the experiments: 800x600 at 120 Hz (ViewSonic)
Temporal noise for every subject
Col change: 76 ms Sound: 65 ms Predictive: 86 ms Button press: 64 ms
These slopes are wrong for AH with buttonpress! ,
Buttonpress (sensorimotor synchronization) vs. other tasks
- is variability consistently less than for other tasks?
Yes for ML, AH, DL poster data, by 20-30 ms. This includes dot-crossing predictive task For data not in table above, DL in 3 different runs shows low temporal noise, and AH ended up with better temporal noise (i think this was partially a data analysis error; Dani has now fixed it)
