This study investigated the extent to which people can develop a global representation of local environments through across-boundary navigation. Participants learned objects’ locations in two misaligned rectangular rooms in an immersive virtual environment. After learning, they adopted a local...

Scully, E.N., Montenegro, C., & Sturdy, C.B.

In both humans and animals, biological differences between males and females has long been a topic of research. In songbirds, sexual dimorphisms can be seen in many species’ plumage and heard in some species’ songs. However, not all songbirds have such overt phenotypic sexual differences, leading...

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...

Three experiments investigated how the room size affects preferential use of geometric and non-geometric cues during reorientation inside a room. We hypothesized that room size may affect preferential use of geometric and non-geometric cues by affecting the encoding of the cues (the encoding...

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,...

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...

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...

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...
