    • Assessing the psychological health of captive and wild apes: A response to Ferdowsian et al. (2011). 

      Rosati, Alexandra G.; Herrmann, Esther; Kaminski, Juliane; Krupenye, Christopher; Melis, Alicia P.; Schroepfer, Kara; Tan, Jingzhi; Warneken, Felix; Wobber, Victoria; Hare, Brian (American Psychological Association (APA), 2013)
      As many studies of cognition and behavior involve captive animals, assessing any psychological impact of captive conditions is an important goal for comparative researchers. Ferdowsian and colleagues (2011) sought to address ...
    • Bonobos Exhibit Delayed Development of Social Behavior and Cognition Relative to Chimpanzees 

      Wobber, Victoria Elizabeth; Wrangham, Richard W.; Hare, Brian (Elsevier, 2010)
      Phenotypic changes between species can occur when evolution shapes development. Here, we tested whether differences in the social behavior and cognition of bonobos and chimpanzees derive from shifts in their ontogeny, ...
    • Breed Differences in Domestic Dogs' (Canis familiaris) Comprehension of Human Communicative Signals 

      Wobber, Victoria Elizabeth; Hare, Brian; Koler-Matznick, Janice; Wrangham, Richard W.; Tomasello, Michael (John Benjamins Publishing Company, 2009)
      Recent research suggests that some human-like social skills evolved in dogs (Canis familiaris) during domestication as an incidental by-product of selection for “tame” forms of behavior. It is still possible, however, that ...
    • Comparative Cognitive Development and Endocrinology in Pan and Homo 

      Wobber, Victoria Elizabeth (2012-08-23)
      Key insights into the evolutionary origins of human social behavior can be gained via study of our closest living relatives, bonobos (Pan paniscus) and chimpanzees (Pan troglodytes). Despite being equally related to humans, ...
    • Differential Changes in Steroid Hormones Prior to Competition in Bonobos and Chimpanzees 

      Wobber, Victoria Elizabeth; Hare, Brian; Maboto, Jean; Lipson, Susan Fay; Wrangham, Richard W.; Ellison, Peter T. (National Academy of Sciences, 2010)
      A large body of research has demonstrated that variation in competitive behavior across species and individuals is linked to variation in physiology. In particular, rapid changes in testosterone and cortisol during competition ...
    • Great Apes Prefer Cooked Food 

      Wobber, Victoria Elizabeth; Hare, Brian; Wrangham, Richard W. (Elsevier, 2008)
      The cooking hypothesis proposes that a diet of cooked food was responsible for diverse morphological and behavioral changes in human evolution. However, it does not predict whether a preference for cooked food evolved ...
    • Psychological Health of Orphan Bonobos and Chimpanzees in African Sanctuaries 

      Wobber, Victoria Elizabeth; Hare, Brian (Public Library of Science, 2011)
      Background: Facilities across Africa care for apes orphaned by the trade for "bushmeat." These facilities, called sanctuaries, provide housing for apes such as bonobos (Pan paniscus) and chimpanzees (Pan troglodytes) who ...
