(A) Mean self-reported fear of movement-related pain (+SE’s) during the CS movements in the predictable (CS+/CS−) and the unpredictable group (CS_u1/CS_u2) during the two acquisition blocks (ACQ1-2), and (B) mean eyeblink startle amplitudes (+SE’s) during the CS movements and the classes of GS movements (CLASS1–3) in the predictable and the unpredictable group during the generalization blocks (G1–G2). (A) Self-reported fear of movement-related pain during acquisition (CSs). (B) Self-reported fear of movement-related pain during generalization (CSs and GSs).
