Animals and music: Between cultural definitions and sensory evidence

It was once thought that solely humans were capable of complex cognition but research has produced substantial evidence to the contrary. Art and music, however, are largely seen as unique to humans and the evidence seems to be overwhelming, or is it? Art indicates the creation of something novel, not naturally occurring in the environment. To prove its presence or absence in animals is difficult. Moreover, connections between music and language at a neuroscientific as well as a behavioural level are not fully explored to date. Even more problematic is the notion of an aesthetic sense. Music, so it is said, can be mimetic, whereas birdsong is not commonly thought of as being mimetic but as either imitation or mimicry and, in the latter case, as a ‘mindless’ act (parrots parroting). This paper will present a number of examples in which animals show signs of responsiveness to music and even engage in musical activity and this will be discussed from an ethological perspective. A growing body of research now reports that auditory memory and auditory mechanisms in animals are not as simplistic as once thought and evidence suggests, in some cases, the presence of musical abilities in animals

Mirror neurons and humanity’s dark side

The last two decades have revealed brain mechanisms in birds and primates showing that, contrary to earlier prejudices, some birds can do things (cognitive and affective) on par with or even better than great apes and humans. The old dichotomies are breaking down; but the dark side is that these insights come at a time in the Anthropocene when humans have caused and continue to cause mass extinctions

Evolution of human language: duetting as part of prosociality and cognition

The evolution of human language is a topic that has received undiminished attention. Numerous hypotheses for the origin of human language have been proposed, including gestural communication found specifically among apes. This study advances the hypothesis that human evolution, including human language development, is three-pronged: prosocial, cognitive, and collaborative. Duetting and turn-taking in primates are used as pivotal examples of how bonding leads to joint action and collaboration. It points out that such vocal behavior itself may be a crucial precursor of language evolution in the sense that it is explicitly focused on a conspecific. Some current hypotheses have acknowledged duetting as an important perceptual and behavioral example of synchronicity. Some forms of synchronized behavior, as found in duetting, synchronized dance, or even shared song, were perhaps crucial evolutionary steps preceding the evolution of human language. Duetting signifies more than that, however, because it is an observable and significant cognitive investment that signals attention toward a partner. This study also advances the hypothesis that affect and cognition would have needed to precede any form of duetting or signs of affiliation such as grooming. Hence, this study, asking what duetting in primates signifies in evolutionary terms, takes a multidisciplinary and multimodal approach to suggest important affective and cognitive steps in the evolution of human language and speech, the chief of which is prosociality. Prosociality, as an attitude and awareness of another, be this as a friend or partner for whom one can do favors or whom one can help, is a model for collaboration and cooperation, and also increased cognition

Brain Size Associated with Foot Preferences in Australian Parrots

Since foot preference of cockatoos and parrots to hold and manipulate food and other objects has been associated with better ability to perform certain tasks, we predicted that either strength or direction of foot preference would correlate with brain size. Our study of 25 psittacine species of Australia found that species with larger absolute brain mass have stronger foot preferences and that percent left-footedness is correlated positively with brain mass. In a sub-sample of 11 species, we found an association between foot preference and size of the nidopallial region of the telencephalon, an area equivalent to the mammalian cortex and including regions with executive function and other higher-level functions. Our analysis showed that percent left-foot use correlates positively and significantly with size of the nidopallium relative to the whole brain, but not with the relative size of the optic tecta. Psittacine species with stronger left-foot preferences have larger brains, with the nidopallium making up a greater proportion of those brains. Our results are the first to show an association between brain size and asymmetrical limb use by parrots and cockatoos. Our results support the hypothesis that limb preference enhances brain capacity and higher (nidopallial) functioning

Avian Anti-Predator Strategies: Specificity of Mobbing and Predator Inspection in the Australian Magpie ('Gymnorhina tibicen') and the Zebra Finch ('Taeniopygia guttata')

Many species have developed anti-predator defences beyond a flight and avoidance response. Some species approach predators (i.e. to mob or inspect) despite the fact that this behaviour might increase risk of capture. At the very least, it seems a counter-intuitive behaviour that requires explanation, even if some advantages may partially counteract the risks. While there have been quite detailed studies of mobbing in birds, predator inspection has only had scant mention and has been based on a study by Kruuk (1976) that, to my mind, rather described mobbing. My research was particularly interested in investigating closely the similarities and differences between mobbing and of predator inspection, having to find more evidence of the latter in birds. The thesis addresses the problem of function in both major forms of approach behaviour and it was my aim to place these questions in an ecological, developmental and territorial context. These questions were tested experimentally in the field using Australian magpies (Gymnorhina tibicen) and in the laboratory using zebra finches (Taeniopygia guttata) by presenting groups of both species with models of predators. Five experiments were conducted between September 2005 to February 2008. The results showed that juvenile dependency had little influence on mobbing/inspection of magpies but the species of predator did produce significant differences in all categories. The magpies discriminated between the aerial and ground predators and altered their response accordingly. The results strongly suggest that mobbing and predator inspection are not behaviours that are closely related, even though some overlap occurs, and are, in fact, functionally different: For instance, eye preference to view a model predator was analysed and it was found that predominantly the left eye (the right hemisphere of the brain) was used during inspection-only approaches while no bias was found during mobbing behaviour. To conclude, my results show, for the first time, that mobbing and predator inspection are functionally different and that predator inspection is functionally different from general exploration behaviour

Are animals autistic savants.

Do animals have privileged access to lower level sensory information before it is packaged into concepts, as it has been argued for autistic savants

Are Animals Autistic Savants?

Similarities in behaviour between autistic savants and animals have been suggested, most notably by Temple Grandin in her book 'Animals in Translation' (2005), and this theory seems to have gained some consensus among other neuroscientists who are not specialists in animal cognition. Here we aim to discuss two specific parallels between the behavioural characteristics of animals and those of autistic savants that have been raised in relation to Grandin's book. Autistic savants show extraordinary skills, particularly in music, mathematics, and drawing
