Schematic representation of the test trial. (a) When the baiter shows the carrot to the horse. (b) When the baiter removes the obstacle and goes into the middle and behind the informants. (c) When the two informants go behind the buckets and make choices by pointing at each bucket. Here, I1 acts as a guesser and I2 acts as a knower.
