  1. Standard errors clustered at (unique) Bin ID in parentheses. All models report time (date of data collection) and weekday fixed effects.
  2. The variable extra trial bins takes values 1 = if there are extra trial factors, and 0 = otherwise. The variable floor number represents floor numbers and takes values between 1(ground floor) and 8 (sixth floor).
  3. *p < 0.1, **p < 0.05, ***p < 0.001.
