Skin conductance responses (SCR) during fear acquisition (A) and extinction (B) to the CS+ and CS−. There was a significant Block by Trial Type interaction during acquisition, F(2, 118)=8.04, p=.001, and a significant effect of Block during extinction, F(3, 135)=4.24, p<.01. Abbreviations: CS+=reinforced conditioned stimulus; CS−=non-reinforced conditioned stimulus.

**=p<.001 effect of Trial Type, CS+ vs CS− in Acq 2 and 3;

*=p<.01 main linear effect of Extinction Block (Ext1, Ext2, Ext3, and Ext4) across Trial Type
