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?

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...

Learning from authoritarian teachers: Controlling the situation or controlling yourself can sustain motivation

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...

Animals make surprising anticipatory and perseverative errors when faced with a midsession reversal of reinforcer contingencies on a choice task with highly predictable stimulus-time relationships. In the current study, we asked whether pigeons could learn to anticipate changes in reinforcement...

Octave equivalence describes the perception that notes separated by a doubling in frequency sound similar. While the octave is used cross-culturally as a basis of pitch perception, experimental demonstration of the phenomenon has proved to be difficult. In past work, members of our group...

We compared French speaking and South Asian (SA) immigrant families having preschool children in an English speaking region in Canada, with regard to the parents’ attitudes towards minority language (ML) maintenance, ML use at home, and exposure of children to ML media. Parents in both groups had...

A prevailing argument posits that distal landmarks dominate over proximal landmarks as orientation cues. However, no studies have tested this argument or examined the underlying mechanisms. This project aimed to close this gap by examining the roles of relative cue precision and prior knowledge...

Seasonal variability in habitat structure may have shaped acoustic signals and repertoires in the black-capped and boreal chickadees
Download2017-01-01
Many songbird species have evolved multiple vocalizations, or repertoires, that function to communicate various biological signals. More diverse repertoires may have evolved in response to the effects of seasonal variation in habitat structure on signal transmission. Such changes in habitat...
