Figure 4.

Bars (with standard errors) depict the (A) valence, (B) arousal, and (C) anxiety ratings after the two generalization phases. Participants preexposed to the learning contexts (preexposure group) rated the CTX+ (black bars) equally to CTX− (gray bars) and less negative and less arousing than G-CTX (white bars). On the contrary, participants, who were not preexposed to the learning contexts (no-preexposure group) showed differential responses to CTX+ versus CTX− and stronger generalization. (*) P < 0.05; (***) P > 0.001.
