Figure 8

Mean percentage of choices to each location based on position in the chunk in Experiment 1, Phase 5. 0 indicates the correct location, 1 indicates the circle clockwise to the correct location, −1 indicates the circle anti-clockwise to the correct location, etc. Note that since pigeons tend to peck to a touchscreen in bursts, a response to the same location as the previously correct location was not considered to be an incorrect choice but rather a perseveration. Hence, these pecks were ignored in the analysis resulting in the locations having 0 responses.
