Figure 6.

(A) Photographs of the Coiled Hose and Rubber Snake stimuli (left to right, respectively) as they were seen by the animals. (B) Average frequency of Tension Behaviors displayed by all groups in the Baseline, Grape Only, Coiled Hose and Rubber Snake conditions. (C) Average frequency of Tension Behaviors for Groups C (diamonds) and A-ibo (stars) across all object pairs included in the study; rectangles indicate conditions where Group A-ibo < Group C (p < .05). Gray symbols identify the Neutral objects, whereas black symbols denote the Aversive objects. (D) Average Grape Retrieval Latency (GRL) for all groups during the Coiled Hose and Rubber Snake series. (E) Average GRL data for Groups C and A-ibo across all object pairs included in the study; rectangles highlight the conditions where Group A-ibo < Group C (p < .05). Symbols and color conventions are the same as panel C. Vertical bars in B and D represent the SEM.# p < .05, mean of all conditions relative to Groups C and H-ibo; ^* p < .05, mean of all conditions relative to Group C.
