Communication, Association, or Methodological Muddle, with Examples
from Part Two - Evolutionary Perspectives
Published online by Cambridge University Press: 23 June 2026
Pointing, for humans, is a communicative act – we intend to share information with one another by pointing. The intentional nature of ape pointing has been questioned, but a substantial set of data show that apes in communicative contexts alter their behavior with audience and attentional variables, indicating intentional communication. In contrast, the comprehension (receiving and understanding the information) of the point gesture in apes and other nonhumans has most often been tested using object choice task (OCT), an artificial experimental task removed from typical communicative contexts. This recent preoccupation with nonhuman point following has been fueled, in part, by the claim that dogs perform well at these tasks and apes do not. This claim, in turn, was built on the assumption that the OCT requires the understanding of the communicative nature of the point gesture – specifically it requires understanding the signaler’s intent to communicate – an assumption not backed up by historical or recent data. The chapter presents a review and a case study supporting three hypotheses: 1) Apes and dogs follow points quite well in the OCT if simple associative mechanisms like local enhancement can be used to solve the problem; 2) Some apes and dogs may understand the communicative intent underlying point gestures, however, these are the minority and likely require enriched environments; and 3) Methodologies and interpretations must be continuously and critically evaluated, especially when drawing species comparisons.
