This table shows Ordered Logit Regressions of a variable that takes value 0 if Predicted < Actual Performance, 1 if Predicted = Actual Performance and 2 if Predicted >Actual Performance on the 2D:4D digit ratio. All regressions include sessions fixed effects and robust standard errors clustered by session are reported in brackets.
