About Britt Singletary

I am a doctoral candidate in Biological Anthropology in the School of Anthropology, and I am minoring in Ecology and Evolutionary Biology through the EEB department here at the University of Arizona. My primary advisor is Ivy Pike, PhD. I am interested in investigating the use of complex signals (e.g., multiple messages sent through multiple sensory modalities) in human and nonhuman primate groups. I am currently All But Dissertation (ABD) and working on my dissertation project, entitled "Who cares? How caregivers influence communicative and cognitive competence during early development."

My dissertation project will investigate how humans develop early communicative and cognitive skills during the pre-verbal development phase through multiple interactions with caregivers other than the primary caregiver. The results of this research may reveal additional benefits associated with the use of extensive allomaternal care in our species, suggesting that it isn’t all about energy. 

I am currently a GTA/Instructor in EEB for ECOL182L.

Projects

Dissertation Project, "Who cares? How caregivers influence communicative and cognitive competence during early development":

Humans are unique in our expression of extensive allomaternal care (AMC—care from someone other than the mother). AMC supplements an infant’s intense energy needs, yet is also very likely to play a significant role in shaping communicative and cognitive development in children, a benefit requiring further exploration. A rich signaling environment enhances infant perceptual abilities, brain development, and cognitive skills. Considerable AMC creates opportunities for children to interact with different signalers (e.g., nannies, grandmothers, uncles, and/or older siblings), which may therefore affect individual fitness outcomes. This research aims to improve our understanding of the evolution and maintenance of human AMC practices by investigating whether AMC influences communicative and cognitive outcomes. This project will examine how care impacts developmental outcomes in children using a novel combination of interdisciplinary methods, including questionnaires, daily diaries, interviews, laboratory tasks, and clinical cognitive measures. Participants will include infants aged 13 to 18 months and their mothers recruited in Tucson, AZ. This study will help determine whether AMC improves early developmental outcomes, such that infants exposed to high levels of AMC develop communicative and cognitive competence sooner than infants exposed to low levels of AMC. Identifying how exposure to AMC creates different cognitive and communicative developmental trajectories will enrich our understanding of why extensive AMC evolved and was maintained in our species.

Research Interests

My background in anthropology is very broad, and I have enjoyed taking many courses across all four subfields, especially in linguistics and archaeology. After primatology, linguistics and ethnomusicology (the study of how humans use music) are my favorite subjects. My  life-long obsession with music and sound has influenced her academic interests in the evolution of communication systems and music, with a focus on nonhuman primate vocalizations. My research aims to consider differences in acoustic strategies and acoustic structures in nonhuman primates according to abiotic and environmental factors, sex, hormone levels, genetic relatedness, parasite load, and overall health, particularly interested in the lemurs of Madagascar. I am particularly interested in investigating the usage of complex signals in humans and nonhuman primates.
