Figure 1.
Overview of a reinforced CS+1 trial, a reinforced CS+2 trial and a CS− trial.
Picture of stimulator signifies delivery of electric shock (US). Lightning bolt: delivery of US placeholder instead of US.
Figure 2.
Fear ratings for CS−, CS+1 and CS+2 across all experimental phases (tr = training, te = test).
Error bars represent the 95-percent point-wise confidence interval.
Figure 3.
US expectancy ratings for CS−, CS+1 and CS+2 across all experimental phases (tr = training, te = test).
Error bars represent the 95-percent point-wise confidence interval.
Figure 4.
Skin conductance responses for CS−, CS+1 and CS+2 across all experimental phases (tr = training, te = test).
Error bars represent the 95-percent pointwise confidence interval.
