Can we trust web-based response time data?
Pinet et al. (2017) Behavior Research Methods Methods Lunch An Intro to Web-Based Experiments 12/02/2019
Using jsPsych with a Black Box Toolkit (BBTK):
- 1. ~60ms delay
- 2. ~0ms inter-keystroke interval (IKI)
Measuring Triplet Keystrokes Replication of Rosenbaum et al. (1984) n=541 Uncertainty = hand switch
- Typing triplets
- Hand switches slow
down the prior keystroke
- Size of effect is pretty
small, but helped by large n and within- subject design Delay IKI
