What is the role of language in social interaction? What does language bring to social encounters? We argue that language can be conceived of as a tool for interacting minds, enabling especially effective and flexible forms of social coordination, perspective-taking and joint action. In a review of evidence from a broad range of disciplines, we pursue elaborations of the language-as-a-tool metaphor, exploring four ways in which language is employed in facilitation of social interaction. We argue that language dramatically extends the (...) possibility-space for interaction, facilitates the profiling and navigation of joint attentional scenes, enables the sharing of situation models and action plans, and mediates the cultural shaping of interacting minds.

Humans are strongly lateralized for manual gestures at both individual and population levels. In contrast, the laterality bias in primates is less strong, leading some to suggest that lateralization evolved after the Pan and Homo lineages diverged. However, laterality in humans is also context-dependent, suggesting that observed differences in lateralization between primates and humans may be related to external factors such as the complexity of the social environment. Here we address this question in wild chimpanzees and examine the extent to (...) which the laterality of manual gestures is associated with social complexity. Right-handed gestures were more strongly associated with goal-directed communication such as repair through elaboration in response to communication failure than left-handed gestures. Right-handed gestures occurred in evolutionarily urgent contexts such as in interactions with central individuals in the network, including grooming reciprocity and mating, whereas left-handed gestures occurred in less-urgent contexts, such as travel and play. Right-handed gestures occurred in smaller parties and in the absence of social competition relative to left-handed gestures. Right-handed gestures increased the rate of activities indicating high physiological arousal in the recipient, whereas left-handed gestures reduced it. This shows that right- and left-handed gestures differ in cognitive and social complexity, with right-handed gestures facilitating more complex interactions in simpler social settings, whereas left-handed gestures facilitate more rewarding interactions in complex social settings. Differences in laterality between other primates and humans are likely to be driven by differences in the complexity of both the cognitive skills underpinning social interactions and the social environment.

Imitation recognition provides a viable platform from which advanced social cognitive skills may develop. Despite evidence that non-human primates are capable of imitation recognition, how this ability is related to social cognitive skills is unknown. In this study, we compared imitation recognition performance, as indicated by the production of testing behaviors, with performance on a series of tasks that assess social and physical cognition in 49 chimpanzees. In the initial analyses, we found that males were more responsive than females to (...) being imitated and engaged in significantly greater behavior repetitions and testing sequences. We also found that subjects who consistently recognized being imitated performed better on social but not physical cognitive tasks, as measured by the Primate Cognitive Test Battery. These findings suggest that the neural constructs underlying imitation recognition are likely associated with or among those underlying more general socio-communicative abilities in chimpanzees. Implications regarding how imitation recognition may facilitate other social cognitive processes, such as mirror self-recognition, are discussed. (shrink)

According to the socio-cognitive revolution hypothesis, humans but not other great apes acquire language because only we possess the socio-cognitive abilities required for Gricean communication, which is a pre-requisite of language development. On this view, language emerged only following a socio-cognitive revolution in the hominin lineage that took place after the split of the Pan-Homo clade. In this paper, I argue that the SCR hypothesis is wrong. The driving forces in language evolution were not sweeping biologically driven changes to hominin (...) social cognition. Our LCA with non-human great apes was likely already a Gricean communicator, and what came with evolution was not a raft of new socio-cognitive abilities, but subtle tweaks to existing ones. It was these tweaks, operating in conjunction with more dramatic ecological changes and a significant increase in general processing power, that set our ancestors on the road to language. (shrink)

The linguistic and cognitive sciences have severely underestimated the degree of linguistic diversity in the world. Part of the reason for this is that we have projected assumptions based on English and familiar languages onto the rest. We focus on some distortions this has introduced, especially in the study of semantics.

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.

The social cognition of domestic cats is a scarcely studied topic due to the reputation of the animal as individualistic. Nevertheless, cats are capable of cognitively demanding cooperative activities such as a communal nest-moving. The cognitive abilities of free-ranging cats are evaluated against the background of the shared intentionality hypothesis, proposed by a research group of Michael Tomasello. Although their comparative studies are carried out on chimpanzees, they are valuable as a source of conceptual work linking empirical cognitive studies with (...) the philosophical accounts of joint agency. We critically analyze theoretical cognitive concepts interpreting the triadic interactions of great apes and the collective hunting among chimpanzees. Contrary to the shared intentionality hypothesis, it is argued that cats have cognitive abilities to share attention, truly cooperate and constitute shared meanings. Finally, we introduce the concept of the natural interaction ritual by Randall Collins and outline its significance for our case study about cats as well as for a general biosemiotic theory of the development of symbols.

Ape species-specific communication is grounded on the present, possesses some referential qualities and is mostly used to request objects or actions from others. Artificial systems of communication borrowed from humans transform apes' communicative exchanges by freeing them from the present (i.e. displaced reference) although requests still predominate as the main reason for communicating with others. Symbol use appears to enhance apes' relational abilities and their inhibitory control. Despite these substantial changes, it is concluded that even though artificial communication enhances thought (...) and enables its expression more openly, it does not create it or modify the motivation behind communicative exchanges.

Through the application of Material Engagement Theory to enactivist analyses of social cognition, this paper seeks to examine the role of material culture in shaping the development of intersubjectivity and long-term scalar transformations in social interaction. The deep history of human sociality reveals a capacity for communities to self-organise at radically emergent scales across a variety of temporal and spatial ranges. This ability to generate and participate in heterogenous, multiscalar relationships and identities demonstrates the developmental plasticity of human intersubjectivity. Perhaps (...) human sociality’s most unique feature is this intersubjective plasticity, that is, the ability for diverse collectivities of individuals and groups to adopt and transition between numerous social identities and behaviours with profound rapidity and flexibility. However, the most influential models in the study of social cognition, the Social Intelligence Hypothesis and Theory of Mind, promote a view of intersubjectivity that is rooted in methodological individualism and primarily understood as a capacity for observation and prediction. This approach leads to significant issues when confronted with the diversity and plasticity of hominin social organisation, particularly in regards to the computational burdens and information processing bottlenecks such scalar changes imply for cognitivist models. This paper examines the metaphysical assumptions in computational models of the mind that result in representational apriorism and an epiphenomenal treatment of material culture that hinder our understanding of the evolution and development of social cognition. Specifically, this article critiques the logics of computation, information processing, representationalism, and content within Neo-Darwinian frameworks that obscure and distort the interrelationships of evolutionary, developmental, ecological and cultural processes. Through a synthesis of material engagement and enactivist approaches to social cognition, this article argues that it is possible to explain the emergent and multiscalar dynamics of hominin sociality in terms of ecologically distributed and developmentally plastic interactions between brains, bodies and material culture.

This thesis presents a communicative account of personhood that argues for the inseparability of the metaphysical and the practical concepts of a person. It connects these two concepts by coupling the question “what is a person” with the question "how does one become a person". It argues that participation in social interactions that are characterized by mutual recognition and giving-and-taking reasons implied by the practical concept of a person is in fact an ecological and developmental condition for an entity to (...) possess the kind of characteristics and capacities such as reflexive self-consciousness addressed by the metaphysical concept. The chief theoretical contribution of the dissertation research lies, accordingly, in demonstrating that an adequate metaphysical concept of a person has to make reference to the kind of social processes that are necessary for the emergence and development of the distinguishing attributes of persons among other moving, perceiving, desiring and cognizing agents. Methodologically, it undertakes an original philosophical analysis that is enriched by an interdisciplinary investigation of several notions and insights from semiotics, comparative and developmental psychology, cognitive science and anthropology. The main argument of the thesis is that one becomes a person through internally recreating a social, communicative process; namely, that of dialogical transformation of habits. We find the paradigmatic case of this social process in mutual persuasion. The internalization of this process in the form of an inner dialogue cultivates a social self that is in ongoing communication with the embodied, organismic self of uncritically habituated attitudes, convictions and desires. This inner dialogue can be conceived as a temporally extended process of self-persuasion, which is characterized by an ongoing strive for attaining higher degrees of self-control; that is, for achieving a more coherent alignment between our habits and the kind of person we would like to be. It starts with self-interpretation and self-evaluation, and culminates in the formation of higher-order desires that facilitate habit-change and novel habit formation in accordance with certain social, moral, aesthetical or intellectual categories and norms one comes to endorse. For this reason, self-induced, deliberate habit-change is also a process of appropriation or self-appropriation, through which we strive to cultivate habits of feeling, thinking, acting that we can deem more truly ours. The thesis demonstrates that the capacity for engaging in this kind of self-persuasion consists chiefly in the capacities for metasemiosis, perspective-taking, and for cultivating habits of reflexivity. It explicates how all these capacities have a social origin and ultimately a social function by showing that they all presuppose certain higher-order communicative patterns that arose through an evolutionary and cultural history, and develop through the internal reconstruction of these patterns as cognitive-semiotic processes. The thesis concludes that becoming a kind of being who can engage in self-persuasion, thus a person, consists ultimately in internalizing the patterns of communicative social interactions in the form of an ongoing auto-communication.

From playing basketball to ordering at a food counter, we frequently and effortlessly coordinate our attention with others towards a common focus: we look at the ball, or point at a piece of cake. This non-verbal coordination of attention plays a fundamental role in our social lives: it ensures that we refer to the same object, develop a shared language, understand each other’s mental states, and coordinate our actions. Models of joint attention generally attribute this accomplishment to gaze coordination. But (...) are visual attentional mechanisms sufficient to achieve joint attention, in all cases? Besides cases where visual information is missing, we show how combining it with other senses can be helpful, and even necessary to certain uses of joint attention. We explain the two ways in which non-visual cues contribute to joint attention: either as enhancers, when they complement gaze and pointing gestures in order to coordinate joint attention on visible objects, or as modality pointers, when joint attention needs to be shifted away from the whole object to one of its properties, say weight or texture. This multisensory approach to joint attention has important implications for social robotics, clinical diagnostics, pedagogy and theoretical debates on the construction of a shared world. (shrink)

We call those gestures “instrumental” that can enhance certain thinking processes of an agent by offering him representational models of his actions in a virtual space of imaginary performative possibilities. We argue that pointing is an instrumental gesture in that it represents geometrical information on one’s own gaze direction, and provides a ritualized template for initiating gaze coordination and joint attention. We counter two possible objections, asserting respectively that the representational content of pointing is not constitutive, but derived from language, (...) and that pointing directly solicits gaze coordination, without representing it. We consider two studies suggesting that attention and spatial perception are actively modified by one’s own pointing activity: the first study shows that pointing gestures help children link sets of objects to their corresponding number words; the second, that adults are faster and more accurate in counting when they point.
