Motivation, Conditioning, and Learning

Togetherness in rodents may be more social than sexual. We've trained rats, mice, and prairie voles to perform a learned response for access to another member of the same species. To our surprise, it does not seem to matter whether the subject rat is sexually motivated by hormones or not, or whether the target animal is receptive or not receptive or the same or opposite sex. These rodents like to be with conspecifics and if a sexual encounter is added to the experience it doesn't matter much. This mechanism seems to support the colonial residential style of these species as Meadow voles, which are more solitary in habits, seem indifferent to social contact with their own species but are motivated to respond for sexual opportunities. Although we continue to write about this problem, laboratory work has been terminated with Professor Matthews’ retirement.

Human Conversation

A new project involves a rigorous behavioral analysis of the interactive patterns of speech sounds in human conversation. Recorded conversations are analyzed for regularities in utterances, interruptions, over-talking, pausing, and vocal loudness. A bout analysis reveals patterns of turn-taking that distinguish intimate, polite, instructional, and dominant conversation formats, among others. Graphical feedback will be explored as a means to modify problematic conversation patterns.
