    Manual Deixis in Apes and Humans.David A. Leavens - 2005 - Interaction Studies. Social Behaviour and Communication in Biological and Artificial Systemsinteraction Studies / Social Behaviour and Communication in Biological and Artificial Systemsinteraction Studies 5 (3):387-408.
    Pointing by apes is near-ubiquitous in captivity, yet rare in their natural habitats. This has implications for understanding both the ontogeny and heritability of pointing, conceived as a behavioral phenotype. The data suggest that the cognitive capacity for manual deixis was possessed by the last common ancestor of humans and the great apes. In this review, nonverbal reference is distinguished from symbolic reference. An operational definition of intentional communication is delineated, citing published or forthcoming examples for each of the defining (...)

    Integration of Visual and Vocal Communication: Evidence for Miocene Origins.David A. Leavens - 2003 - Behavioral and Brain Sciences 26 (2):232-233.
    Corballis suggests that apes lack voluntary control over their vocal production. However, recent evidence implicates voluntary control of vocalizations in apes, which suggests that intentional control of vocal communication predates the hominid-pongid split. Furthermore, the ease with which apes in captivity manipulate the visual attention of observers implies a common cognitive basis for joint attention in humans and apes.

    BIZARRE Chimpanzees Do Not Represent “the Chimpanzee”.David A. Leavens, Kim A. Bard & William D. Hopkins - 2010 - Behavioral and Brain Sciences 33 (2-3):100-101.
    Henrich et al. convincingly caution against the overgeneralization of findings from particular human populations, but fail to apply their own compelling reasoning to our nearest living relatives, the great apes. Here we argue that rearing history is every bit as important for understanding cognition in other species as it is in humans.

    On the Public Nature of Communication.David A. Leavens - 2002 - Behavioral and Brain Sciences 25 (5):631-632.
    Comparative and developmental psychology are engaged in a search for the evolutionary and developmental origins of the perceptions of “intentions” and “desires,” and of epistemic states such as “ignorance” and “false belief.” Shanker & King (S&K) remind us that these are merely words to describe public events: All organisms that can discriminate states of “knowledge” in others have learned to do this through observation of publicly available information.

    Having a Concept “See” Does Not Imply Attribution of Knowledge: Some General Considerations in Measuring “Theories of Mind”.David A. Leavens - 1998 - Behavioral and Brain Sciences 21 (1):123-124.
    That organisms have a concept “see” does not necessarily entail that they attribute knowledge to others or predict others' behaviors on the basis of inferred mental states. An alternative experimental protocol is proposed in which accurate prediction of the location of an experimenters' impending appearance is contingent upon subjects' attribution of knowledge to the experimenter.
