“…That dance-conveyed information may simultaneously guide followers engaged in distinct foraging activities-a property known as pluripotentiality in systems science 47,48 -may go some way towards explaining why studies have often failed to detect clear benefits to this communication system [5][6][7][8][9] . The costs of producing spatial information under ecological contexts in which it is less valuable may be offset by the benefits gained through the dance's motivational, reactivation and reaffirmation functions 1,12,13,49 .…”

“…The costs of producing spatial information under ecological contexts in which it is less valuable may be offset by the benefits gained through the dance's motivational, reactivation and reaffirmation functions 1,12,13,49 . At the same time, because reactivation is also elicited by antennation and trophallaxis, these other transmission pathways may aid in maintaining the dance communication system through such overlapping functionality (i.e., degeneracy 47,48,50 ). In other words, responses to selection pressure favouring the transmission of spatial information may be enhanced, as the dance's reactivation function can be fulfilled through alternative information networks.…”

Network-based diffusion analysis reveals context-specific dominance of dance communication in foraging honeybees

The honeybee (Apis mellifera) dance communication system is a marvel of collective behaviour, but the added value it brings to colony foraging efficiency is poorly understood. In temperate environments, preventing communication of foraging locations rarely decreases colony food intake, potentially because simultaneous transmission of olfactory information also plays a major role in foraging. Here, we employ social network analyses that quantify information flow across multiple temporally varying networks (each representing a different interaction type) to evaluate the relative contributions of dance communication and hivebased olfactory information transfer to honeybee recruitment events. We show that virtually all successful recruits to novel locations rely upon dance information rather than olfactory cues that could otherwise guide them to the same resource. Conversely, during reactivation to known sites, dances are relatively less important, as foragers are primarily guided by olfactory information. By disentangling the contributions of multiple information networks, the contexts in which dance communication truly matters amid a complex system full of redundancy can now be identified.

“…However, from the side of the observer of communicative acts, each nonverbal behavior can be seen as a cue for the intended politeness reading of an utterance. Mason, Domínguez, Winter and Grignolio (2015), in a discussion of redundancy in communication systems, make the argument that given the significance of politeness in Korean society, having multiple cues for honorification is essential. Just as linguistic contrasts are "redundantly" encoded via multiple channels (e. g., voicing contrasts are signaled simultaneously through voice onset time, pitch, duration and other acoustic cues; see Winter 2014), social contrasts are also simultaneously signaled through multiple channels.…”

Multimodal indexicality in Korean: “doing deference” and “performing intimacy” through nonverbal behavior

This study investigates the nonverbal behaviors used in two interconnected relational practices in Korean: “doing deference” towards status superiors and “performing intimacy” towards status equals. We extracted 154 interactions from Korean televised dramas that represented these two relational practices, and annotated the data for various nonverbal behaviors, including body position and orientation, facial expressions, manual gestures, and touching. Our analyses showed that the protagonists in the dramas altered their nonverbal behavior between the two relational practices according to all of the categories that we annotated. Doing deference featured erect but constrained body positions, direct bodily orientation towards the status superior, and suppression of gestures and touching. These behaviors display decreased animatedness and freedom, as well as increased effort, and increased submissiveness. In contrast, performing intimacy displayed more relaxed and reciprocal body positioning, as well as frequent gestures and touching behaviors. The results call into question analyses of politeness phenomena that solely focus on verbal elements in previous descriptions of Korean deference. Ultimately, our results demonstrate the need for more multimodal studies in politeness research.

“…This added “redundancy” is essentially a form of what has been called “degeneracy” in biology and elsewhere (cf. Mason, Domínguez, Winter, & Grignolio, ). That is, different system components (an additional phonetic cue or an additional syllable) realize the same function.…”

The Co‐evolution of Speech and the Lexicon: The Interaction of Functional Pressures, Redundancy, and Category Variation

The sound system of a language must be able to support a perceptual contrast between different words in order to signal communicatively relevant meaning distinctions. In this paper, we use a simple agent-based exemplar model in which the evolution of sound-category systems is understood as a co-evolutionary process, where the range of variation within sound categories is constrained by functional pressure to keep different words perceptually distinct. We show that this model can reproduce several observed effects on the range of sound variation. We argue that phonological systems can be seen as finding a relative optimum of variation: Efficient communication is sustained while at the same time, hidden category variation provides pathways for future evolution.
