Figure 7

The experimental design, hypothetical temporal representations, and observed result of Arcediano, Escobar, and Miller (2005, Experiment 2). (A and B) Groups Ext-S1 and Ext-S2 assessed whether integration was based on two unidirectional links or one bidirectional link. (C) Group Ext-S3 controlled for temporal integration. Open rectangles and letters represent conditioned stimuli; black rectangles represent the footshock unconditioned stimulus; each dashed line represents the retrieved activation of a representation. CR = strong conditioned responding; cr = little or no conditioned responding.
