We show that the law of brevity, i.e. the tendency of words to shorten as their frequency increases, is also found in dolphin surface behavioral patterns. As far as we know, this is the first evidence of the law in another species, suggesting that coding efficiency is not unique to humans. © 2008 Wiley Periodicals, Inc. Complexity, 2009. 

Figures and Tables from this paper

Parallels of human language in the behavior of bottlenose dolphins
TLDR
Dolphins exhibit striking similarities with humans, and various statistical laws of language that are well-known in quantitative linguistics, i.e. Zipf’s law for word frequencies, the law of meaning distribution, and Menzerath's, law have been found in dolphin vocal or gestural behavior.
Efficiency of coding in macaque vocal communication
TLDR
It is shown that the vocal repertoire of the Formosan macaque (Macaca cyclopis) conforms to the pattern predicted by the law of brevity, with an inverse relationship found between call duration and rate of utterance.
The Law of Brevity in Macaque Vocal Communication is not an Artefact of Analysing Mean Call Durations∗
TLDR
It is shown that the negative correlation between mean duration and frequency of use in the vocalizations of Formosan macaques is not an artefact of the use of a mean duration for each call type instead of the customary ‘word’ length of studies of the law in human language.
Linguistic laws in chimpanzee gestural communication
TLDR
A negative correlation between number and mean duration of gestures in sequences, in line with Menzerath's law is found, providing the first evidence that compression underpins animal gestural communication, and highlight an important commonality between primate gesturing and language.
A Law of Word Meaning in Dolphin Whistle Types
TLDR
It can be shown that the behavioral context in which a whistle tends to occur or not occur is shared by different individuals, which is consistent with the hypothesis that dolphins are communicating through whistles.
Brevity is not a universal in animal communication: evidence for compression depends on the unit of analysis in small ape vocalizations
TLDR
The results indicate that adherence to linguistic laws in male gibbon solos depends on the unit of analysis, and conclude that principles of compression are applicable outside of human language, but may act differently across levels of organization in biological systems.
Linguistic laws are not the law in chimpanzee sexual solicitation gestures
TLDR
Ape gesture does not appear to manifest a principle of compression or pressure for efficiency that has been previously proposed to be universal, and the same signals were shown to adhere to these laws when used in a different behavioural context; highlighting that signallers consider signalling efficiency broadly, and diverse factors play important roles in shaping investment in signal production.
Adherence to Menzerath's Law is the exception (not the rule) in three duetting primate species
TLDR
It is shown that adherence to Menzerath's Law is the exception rather than the rule in duetting primates, and it is possible that selection pressures for long-range signals that can travel effectively over large distances was stronger than that of compression in primate duets.
Gelada vocal sequences follow Menzerath’s linguistic law
TLDR
In vocal sequences of wild male geladas (Theropithecus gelada), construct size is negatively correlated with constituent size (duration of calls) and formal mathematical support is provided for the idea that Menzerath’s law reflects compression—the principle of minimizing the expected length of a code.
Compression and the origins of Zipf's law of abbreviation
TLDR
This work generalizes the information theoretic concept of mean code length as a mean energetic cost function over the probability and the magnitude of the types of the repertoire and shows that the minimization of that cost function and a negative correlation between probability andThe magnitude of types are intimately related.

Long-term correlations in the surface behavior of dolphins
TLDR
The findings suggest that dolphins have a long collective memory extending back at least to the 7-th past behavior, the first evidence of long-term correlations in the behavior of a non-human species.
Evidence for social role in a dolphin social network
TLDR
Early evidence is provided that decisions about shifts in activity states in a population of bottlenose dolphin follow such a decision-making process that emerged from the social structure of the population and the need to maintain mixed-sex schools.
Elements of Information Theory
TLDR
The author examines the role of entropy, inequality, and randomness in the design of codes and the construction of codes in the rapidly changing environment.
A Mathematical Theory of Communication
TLDR
It is proved that the authors can get some positive data rate that has the same small error probability and also there is an upper bound of the data rate, which means they cannot achieve the data rates with any encoding scheme that has small enough error probability over the upper bound.
