Holcombe:TemporalNoise

SUPA Sydney University Perception and Action Lab Primer editing help refcard

• Check gradually varying of two patches, have to judge orientation of second when one is vertical, also look up std dev of Arnold tilt orientation
• Try independently varying orientation of the two moving/stationary patterns across trials, like Keeble & Nishida

also see temporal precision and action also see Holcombe:InPhaseTask also see Holcombe:ModellingUncertainty

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

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)
