Effect of feed-time duration on discrimination of vocalizations in a go/no-go operant paradigm
Download2022-01-01
Refining and modifying experimental procedures play a vital role in improving methodology while also reducing animal distress. In this study, we asked if an increase in feed time duration affects discrimination in an operant go/no-go task. Specifically, we used zebra finches’ sexually dimorphic...

Campbell, K. A., Thunberg, S., & Sturdy, C. B.
Of the 10 000 or so known avian species, nearly half belong to the clade Passeri[1]. Also called Oscines, or songbirds, birds in this group are unique in that they possess a morphologically complex vocal organ, the syrinx, which facilitates the production of complex and diverse vocalizations,...

Hear them roar: A comparison of black-capped chickadee (Poecile atricapillus) and human (Homo sapiens) perception of arousal in vocalizations across all classes of terrestrial vertebrates

Recently, evidence for acoustic universals in vocal communication was found by demonstrating that humans can identify levels of arousal in vocalizations produced by species across three biological classes (Filippi et al., 2017). Here, we extend this work by testing whether two vocal learning...

If it ain’t broke don’t fix it: breeding success affects nest-building decisions
2021-01-01
Observational studies in the wild suggest that birds select material to build their nests based on functional aspects of material that promote reproductive success. How birds select material for nest building from the variety of materials available in their environment is unclear. In the current...

Individual acoustic differences in female black-capped chickadee (Poecile atricapillus) fee-bee 1 songs

In songbirds, song has traditionally been considered a vocalization mainly produced by males. 11 However, recent research suggests that both sexes produce song. While the function and 12 structure of male black-capped chickadee (Poecile atricapillus) fee-bee song have been well-13 studied,...

Female zebra finches Taeniopygia guttata will copy the novel foraging choice of males. The degree to which they do so, however, can vary considerably. Among-individual differences in social learning and their underlying neural pathways have received relatively little attention and remain poorly...

If speech-language pathologists are to identify bilingual children in need of intervention, it is essential to understand the normal variations of bilingual acquisition and how it is the same or different from monolingual development. In this paper, we present an overview of the basics of...

Learning about construction behaviour from observing an artefact: can experience with conspecifics aid in artefact recognition?
Learning about construction behaviour from observing an artefact: can experience with conspecifics aid in artefact recognition?
Download2021-01-01
Observation of or interaction with the enduring products of behaviour, called ‘social artefacts’ (e.g. an abandoned nest) are a potential source of social information. To learn from an artefact, that artefact needs to be recognized as the product of a behaviour that can provide relevant...

Chaffee, Kathryn E., Noels, Kimberly A., Sugita McEown, Maya
Positive psychology encompasses the study of positive outcomes, optimal functioning, and resilience in difficult circumstances. In the context of language learning, positive outcomes include academic engagement, self-determined motivation, persistence in language learning, and eventually becoming...

Category perception, as Herrnstein (1990) defined it, is a powerful and pervasive cognitive ability possessed by every species in which it has been adequately tested. We have studied category perception of vocal communication signals in songbirds for over 20 years. Our first studies provided us...
