Several language experiments have been carried out on apes and other animals aiming to narrow down the presumed qualitative gap that separates humans from other animals. These experiments, however, have been driven by the understanding of language as a purely symbolic sign system, often connected to a profound disinterest for language use in real situations and a propensity to perceive grammatical and syntactic information as the only fundamental aspects of human language. For these reasons, the language taught to apes tends (...) to discard iconic and indexical elements in favour of symbolic signs. This paper sheds light on the iconic components of human language, with close attention to the iconic properties of language as present in the ape language experiments. We emphasise the role of the body in the interpretation and production of iconic signs, while demonstrating the need to take into account the Umwelt theory in the research paradigm of the experiments. Uexküll’s Umwelt theory is used to exemplify the methodological problems connected to the teaching of human language to other animal species; furthermore, we discuss how the modelling capacities of language affect the biological layer that constitutes the animal Umwelt. Language is analysed as a particular case of Umwelt transition, and as such its implications are further discussed in the article. With this paper, we enrich the discussion surrounding the human-ape pidgin language by advocating for the need to include iconic components as vital parts of this research area. With this inclusion, we uncover the inter-dependency of iconic, indexical and symbolic signs in human language, aiming to further develop the research paradigm of the ape language experiments.

The analysis of social communication in other-than-human animals poses several theoretical challenges due to the complexity of individual and extra-individual variables. Some previous studies have found a valuable solution in Uexküll’s work by expanding and adapting its usage for the study of communication in a heurtistic manner. An Umwelt analysis provides a theoretical toolbox, which allows researchers to take an emic perspective on the lives and phenomenal world of other animals. However, Umwelt and its elaborations do not allow for a (...) clear distinction between acts of perception and communication and seem to ignore factors that escape the specific communication contexts under analysis. Thus, moving away from the existing linear and cyclical approaches to communication, we propose a complementary approach to the study of social communication by combining Barnlund’s transactional model of communication with Umwelt theory and the functional circle more specifically. Our elaborated model conceives social communication as the process of creating meaning through the interaction of two subjects and emphasizes the role of species-specific and individual features in its creation. Our goal is to re-evaluate the research on social communication of other-than-human animals by advocating for the theoretical and empirical potential of Umwelt, especially pertaining to animals with complex Umwelten. Our model offers a valuable solution to the analysis of intraspecies communication that accounts for the role of private and public cues as well as the subjects’ specific behaviors, messages, and context in the creation of meaning.

This paper addresses the biosemiotic dimensions of human relationship with captive animals and aims to uncover how these factors influence handling practices and human-animal interactions within zoological gardens. Zoological gardens are quintessential hybrid environments, and as such, they are places of interspecies interactions and mutual influences. These interactions are profoundly shaped by human attitudes towards animals. The roots of these attitudes can be found at the cultural and institutional levels as well as at the biosemiotic level. Previous studies have suggested (...) that keepers’ attitudes towards animals have direct influences on their handling style and, consequently, have an impact on animals’ perception of keepers and other humans. This suggests that the type of relationship between keepers and animals can translate into handling styles that may affect animals’ perceptions of humans and worsen or improve their welfare. In this paper, we present a case study involving chimpanzees’ keepers at the Tallinn Zoological Gardens. A series of interviews were conducted, which aimed to uncover the way keepers understand their relationships with captive animals and how this influences handling. This work offers a comparative approach by bringing forward the experiences of keepers who work with various animal species belonging to different taxa and class. Such an approach aims to highlight the biosemiotic factors behind the emergence of different types of keeper-animal relationships. We expect to uncover whether extremely different Umwelten may shape human-animal bonds. By highlighting the agency of animals in daily activities and work routine, we also aim to initiate a discussion on the way animals influence handling practices within zoological gardens. Our objective is to understand how individual animals influence handling practices within zoological gardens. (shrink)
