This study is about a series of operational acts of identification, such as interpretations, categorizations, representations, classifications, through which past materials have acquired their meaning and therefore identity. Furthermore, this meaning-making will be demonstrated always to be...

The foremost goal of this thesis is to integrate the study of animal cognition with the field of animal personality. In the early 20th century, Pavlov integrated these fields by describing an interaction between associative learning and dogs that exhibited different behavioural types. Since...

The songs of many songbird species vary geographically, yet, the songs of black-capped chickadees (Poecile atricapillus) show remarkable consistency across most of the species’ North American range. Previous research has described subtle variations in the song of this species by comparing songs...

Chickadees produce many vocalizations, including the chick-a-dee call that they use as a mobbing call in the presence of predators. Previous research has shown that chickadees produce more D notes in their mobbing calls in response to high-threat predators compared to low-threat predators, and...

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...

Pitch perception is important in both music and language perception in humans. Vocal learners, including humans, share the property of learning their vocalizations from a tutor when young. Similar behavioural and neural mechanisms underlying vocal production among different species of vocal...

Songbirds (order Passeriformes, suborder Oscines) have captured the attention of scientists and non-scientists alike with their vocal signals. The black-capped chickadee (genus Poecile) uses its namesake call, chick-a-dee, to convey a variety of information. In Chapter 2 and 3, I examine the...

The black-capped chickadee (Poecile atricapillus) is a non-migratory songbird found throughout North America who communicates primarily through its numerous vocalizations, each with various functions. The vocalizations of the black-capped chickadee can be divided into calls and songs. Calls serve...
