Sex differences have been identified in a number of black-capped chickadee vocalizations and in the chick-a-dee calls of other chickadee species [i.e., Carolina chickadees (Poecile carolinensis)]. In the current study, 12 acoustic features in black-capped chickadee chick-a-dee calls were...

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 chick-a-dee calls which 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 may...

Chickadees are high­metabolism, non­migratory birds, and thus an especially interesting model for studying how animals follow patterns of food availability over time. Here, we studied whether black­capped chickadees (Poecile atricapillus) could learn to reverse their behavior and/or to...

Two experiments investigated how people use buildings and street configurations to reorient in large-scale environments. In immersive virtual environments, participants learned objects’ locations in an intersection consisting of four streets. The objects’ locations were specified by two cues: a...

We investigated how humans use multiple landmarks to locate a goal. Participants searched for a hidden goal location along a line between two distinct landmarks on a computer screen. On baseline trials, the location of the landmarks and goal varied, but the distance between each of the landmarks...

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...

Writing over a century ago, Darwin hypothesized that vocal expression of emotion dates back to our earliest terrestrial ancestors. If this hypothesis is true, we should expect to find cross-species acoustic universals in emotional vocalizations. Studies suggest that acoustic attributes of...

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...
