Is Social Rank Correlated With Cognitive Ability In Black-Capped Chickadees?, Gloria Hyun Young Cho
Is Social Rank Correlated With Cognitive Ability In Black-Capped Chickadees?, Gloria Hyun Young Cho
Electronic Thesis and Dissertation Repository
Traditionally, dominant animals have been regarded as better competitors in all aspects of life, including cognition. However, the survival and reproductive advantages of being a dominant chickadee are surprisingly modest. It is possible that subordinate individuals compensate for the disadvantages of a lower rank with better cognitive abilities. If dominants are monopolizing prime food sources, subordinates may have developed better associative learning skills by learning to associate novel types of stimuli with food rewards. In this thesis, I asked whether dominance rank is correlated with cognitive ability in Black-capped Chickadees. I determined dominance rank in six flocks of six chickadees, …

Multisensory Associative Learning And Multisensory Integration, Sebastien Lauzon
Electronic Thesis and Dissertation Repository
Human multisensory experiences with the world rely on a combination of top-down and bottom-up influences, a process that changes throughout development. The present study explored the relationship between multisensory associative learning and multisensory integration using encephalography (EEG) and behavioural measures. While recording EEG activity, participants were exposed to novel pairings of non-sociolinguistic audiovisual stimuli of varying presentation probability while performing a detection task. The same stimuli were then used in another detection task, which was followed by an analogous behavioural speeded-response task, both of which kept probabilities equal and tested for multisensory integration. Significant relationships were found in fronto-central and …
