Ape Communication

Human communication has been described as a contextual social inference process. Research into great ape communication has been inspired by this view to look for the evolutionary roots of the social, cognitive, and interactional processes involved in human communication. This approach has been highly productive, yet it is often compromised by a too-narrow focus on how great apes use and understand individual signals. In this paper, we introduce a computational model that formalizes great ape communication as a multi-faceted social inference process that relies on information contained in the signal, the relationship between communicative partners, and the social context. This model makes accurate qualitative and quantitative predictions about real-world communicative interactions between semi-wild-living chimpanzees. When enriched with a pragmatic reasoning process, the model explains repeatedly reported differences between humans and great apes in the interpretation of ambiguous signals (e.g. pointing gestures). This approach has direct implications for observational and experimental studies of great ape communication and provides a new tool for theorizing about the evolution of uniquely human communication.

Abstract Archival, correlational, and experimental studies converge showing strong links between societal threat and authoritarianism. However, inconsistent with the social cognitive studies showing that our perception of the reality is systematically biased, the literature on the threat-authoritarianism relations has largely ignored the connection between the actual societal threat and its perception. In this study, we analyzed the relation between objective societal threat and authoritarians’ perception of it, hypothesizing that authoritarians would tend to overestimate societal threat and that such overestimation would increase the endorsement of authoritarian attitudes and the preference for authoritarian political systems. Using an experimental approach, we studied the relations between right-wing authoritarianism (RWA), actual societal threat (manipulated as low vs. moderate), and perceived societal threat working with an Italian community sample (N = 209, Mage = 29.70, SD = 9.53, 64.1% women). Actual threat and RWA equally predicted participants’ threat perception, while their interaction did not. In turn, threat perception further increased RWA and support to authoritarian political system. We discussed the results in terms of a vicious circle whereby authoritarians overestimate societal threat and such overestimation reinforces authoritarian attitudes.

Representational Gestures

This paper investigates the social-cognitive and motivational complexities underlying prelinguistic infants’ gestural communication. With regard to deictic referential gestures, new and recent experimental evidence shows that infant pointing is a complex communicative act based on social-cognitive skills and cooperative motives. With regard to infant representational gestures, findings suggest the need to re-interpret these gestures as initially non-symbolic gestural social acts. Based on the available empirical evidence, the paper argues that deictic referential communication emerges as a foundation of human communication first in gestures, already before language. Representational symbolic communication, instead, emerges as a transformation of deictic communication first in the vocal modality and, perhaps, in gestures through non-symbolic, socially situated routines.

We present an exploratory study of forest-living orangutan pantomiming, i.e. gesturing in which they act out their meaning, focusing on its occurrence, communicative functions, and complexities. Studies show that captive great apes may elaborate messages if communication fails, and isolated reports suggest that great apes occasionally pantomime. We predicted forest-living orangutans would pantomime spontaneously to communicate, especially to elaborate after communication failures. Mining existing databases on free-ranging rehabilitant orangutans' behaviour identified 18 salient pantomimes. These pantomimes most often functioned as elaborations of failed requests, but also as deceptions and declaratives. Complexities identified include multimodality, re-enactments of past events and several features of language (productivity, compositionality, systematicity). These findings confirm that free-ranging rehabilitant orangutans pantomime and use pantomime to elaborate on their messages. Further, they use pantomime for multiple functions and create complex pantomimes that can express propositionally structured content. Thus, orangutan pantomime serves as a medium for communication, not a particular function. Mining cases of complex great ape communication originally reported in functional terms may then yield more evidence of pantomime.

The imaginative powers of humans obviously exceed those of other species; however these characteristics and knowledge did not spring from nowhere. Instead they evolved on the shoulders of the distinctive psychology of man’s pre-human ancestors. This chapter defines the key characteristics of the ancestral foundations of man and describes the evidence in great ape behaviour for two aspects of imagination. The first level of imagination is inventiveness. Inventiveness is the capacity to generate novel and diverse behavioural responses to any given environmental circumstance. In the experimental studies presented in this chapter wherein chimpanzees are tasked to solve particular problems, it was found that great apes such as gorillas, orang-utans, and chimpanzees display imaginative skills compared to other primates. The second aspect of imagination refers to the capacity to operate mentally in a ‘pretend’ world. This second level of imagination is higher than inventiveness as it requires holding mind distinctions between the hypothetical and real world. Although the experimental studies generated intriguing results, these results are limited, and while the pretence in apes should be observable, it is dominated by the manifestation of a more general capacity for secondary representation.

Manual Gesture

Scholars have often reasoned that vocalizations are extremely limited in their potential for iconic expression, especially in comparison to manual gestures (e.g., Armstrong & Wilcox, 2007; Tomasello, 2008). As evidence for an alternative view, we first review the growing body of research related to iconicity in vocalizations, including experimental work on sound symbolism, cross-linguistic studies documenting iconicity in the grammars and lexicons of languages, and experimental studies that examine iconicity in the production of speech and vocalizations. We then report an experiment in which participants created vocalizations to communicate 60 different meanings, including 30 antonymic pairs. The vocalizations were measured along several acoustic properties, and these properties were compared between antonyms. Participants were highly consistent in the kinds of sounds they produced for the majority of meanings, supporting the hypothesis that vocalization has considerable potential for iconicity. In light of these findings, we present a comparison between vocalization and manual gesture, and examine the detailed ways in which each modality can function in the iconic expression of particular kinds of meanings. We further discuss the role of iconic vocalizations and gesture in the evolution of language since our divergence from the great apes. In conclusion, we suggest that human communication is best understood as an ensemble of kinesis and vocalization, not just speech, in which expression in both modalities spans the range from arbitrary to iconic.

Abstract. Research on the neural mechanisms underlying Gilles de la Tourette syndrome (GTS) has mostly concentrated on abnormalities in basal ganglia circuits. Recent alternative accounts, however, focused more on social and affective aspects. Individuals with GTS show peculiarities in their social and affective domain, including echophenomena, coprolalia, and nonobscene socially inappropriate behavior. This article reviews the experimental and theoretical work done on the social symptoms of GTS. We discuss the role of different social cognitive and affective functions and associated brain networks, namely, the social-decision-making system, theory-of-mind functions, and the so-called “mirror-neuron” system. Although GTS affects social interactions in many ways, and although the syndrome includes aberrant social behavior, the underlying cognitive, affective, and neural processes remain to be investigated.

Abstract. Connecting the social cognitive approach of human agency by Bandura (1997) and activity theory by Leontiev (1978) , this paper proposes a new theoretical framework for analyzing and understanding employee participation in organizational decision-making. Focusing on the social cognitive concepts of self-reactiveness, self-reflectiveness, intentionality, and forethought, commonalities, complementarities, and differences between both theories are explained. Efficacy in agency is conceived as a cognitive foundation of work motivation, whereas the mediation of societal requirements and resources through practical activity is conceptualized as an ecological approach to motivation. Additionally, we discuss to which degree collective objectifications can be understood as material indicators of employees’ collective efficacy. By way of example, we explore whether an integrated application of concepts from both theories promotes a clearer understanding of mechanisms connected to the practice of employee participation.
