How many trials were conducted for the "Can See" condition in the Yamamoto study?

The "Can See" condition in the Yamamoto study was designed to observe the helping behavior of chimpanzees when they had visual access to one another. A total of 48 trials were conducted for this condition. This number reflects the structured approach of the study, allowing researchers to gather sufficient data to analyze the chimpanzees' ability to understand cues about helping behavior in a controlled environment.

This design was essential because it illuminated aspects of social cognition and cooperation among the chimpanzees, providing significant insights into their behavior. The choice of 48 trials strikes a balance, ensuring that the study was neither too limited to yield meaningful conclusions nor too extensive to become unwieldy. Thus, the figure of 48 trials is pivotal in supporting the validity of the findings regarding the chimpanzees’ helping behavior within the "Can See" condition.
