Sarah Pope's research explores how familiar solution strategies block better ones from being adopted. Sarah received her Doctorat en Psychologie from Aix-Marseille University in France and her PhD in Neuroscience from Georgia State University in the United States. Sarah has worked with chimpanzees for seven years, as well as several other nonhuman primate species including baboons and bonobos. Recently, Sarah assessed baboons' and chimpanzees' responses to a touchscreen task, which measured their abilities to replace a familiar solution strategy with a more creative one. She also used this task to explore variation in problem-solving approach within humans, both across age groups and cultures.
After receiving funding from the National Geographic Society, Sarah recently investigated cross-cultural differences in problem-solving approach between Westerners and the semi-nomadic Himba of northern Namibia. This research has led her to question how formal education might suppress problem solving creativity in humans.
Currently, Sarah is a post doctoral researcher at University of Texas at Austin in Dr. Cristine Legare's Evolution and Ontogeny of Culture and Cognition lab.
Sarah is working on the NSF-funded EVO-Learn project (Evolution, Variability, and Ontogeny of Learning). Over the next few years Sarah will be conducting fieldwork around the world exploring cross-cultural differences in teaching and learning strategies.
Cognitive set occurs when a known or familiar solution blocks a better alternative.
THE LS-DS Task
The Learned Strategy - Direct Strategy task is a nonverbal, non-arithmetic measure of cognitive flexibility. Unlike typical metrics, the LS-DS task does not require subjects to switch away from a learned strategy. Subjects learn, across three Training levels, how to select Square1 and then Square2 of a demonstration and then select the Triangle. This Square1-Square2-Triangle solution constitutes the Learned Strategy (demonstrated by the white hand). However, in PROBE trials, the Triangle appears alongside the demonstration thereby allowing subjects to either continue to employ their Learned Strategy or adopt the more efficient Direct Strategy (i.e. just selecting the Triangle; demonstrated by the yellow hand).
Sarah's dissertation research utilized the LS-DS task to compare cognitive set (becoming stuck in a response strategy) between primate species and to assess the developmental and cultural influences on humans' ability to break cognitive set.
Sarah's current research explores how cognitive set evolved within the primate lineage and how it varies across human cultures.
Cognitive Flexibility in Nonhuman Primates
To assess a likely evolutionary trajectory of cognitive set within the primate species, she created the nonverbal, computerized LS-DS task and tested baboons', chimpanzees', and humans' abilities to forsake a learned solution strategy in order to adopt a more efficient alternative.
Perceptual and Conceptual Influences
During her research, perceptual influences on cognitive set have also been investigated by tracking subjects’ eye-movements during LS-DS task performance and conceptual influences have been manipulated across multiple studies.
To explore the role of culture and educational background on cognitive flexibility in humans, Sarah compared susceptibility to cognitive set on the LS-DS task between American participants and the semi-nomadic Himba of northern Namibia. See Fieldwork for more information.
Additional Research Interests
Evolution of Imitation
Sarah is also interested in the association between social cognition and imitation in humans and nonhuman primates. She recently finalized a study which sought to understand the neural underpinnings of imitation in chimpanzees by teaching them to play a ‘Do As I Do’ imitation game and then identifying changes in white matter connectivity between Pre- and Post- training brain images, compared to controls.

Sarah's fieldwork focuses on the problem solving strategies evoked by the semi-nomadic Himba of northern Namibia. By comparing Himba residing in urban locations to those living in traditionally remote villages, it is possible to elucidate the impact of globalization on cognitive and perceptual processing. Sarah has also conducted research in Belize and France.
