Inferences About Guessing And Knowing By Chimpanzees (Pan Troglodytes), Daniel J. Povinelli, Kurt E. Nelson, Sarah T. Boysen
Sentience Collection
The visual perspective-taking ability of 4 chimpanzees (Pan troglodytes) was investigated. The subjects chose between information about the location of hidden food provided by 2 experimenters who randomly alternated between two roles (the guesser and the knower). The knower baited 1 of 4 obscured cups so that the subjects could watch the process but could not see which of the cups contained the reward. The guesser waited outside the room until the food was hidden. Finally, the knower pointed to the correct cup while the guesser pointed to an incorrect one. The chimpanzees quickly learned to respond to the knower. …

Vocal Recognition Of Pups By Mother Mexican Free-Tailed Bats, Tadarida Brasiliensis Mexicana, Jonathan P. Balcombe
Vocal Recognition Of Pups By Mother Mexican Free-Tailed Bats, Tadarida Brasiliensis Mexicana, Jonathan P. Balcombe
Sentience Collection
The ability of Mexican free-tailed bat mothers and pups to recognize vocalizations of their presumptive kin (pup isolation calls and mother echolocation calls, respectively) was tested using playbacks of recorded calls. Captive individuals were presented with calls of two bats, one presumptive kin and the other a stranger, from opposite sides of a circular wire arena. Response was determined by amount of time spent on each side of the arena, time spent in contact with a cloth bat model in front of each speaker, and number of separate contacts with each model. For the latter two measures, mothers showed a …
Long-Term Effects Of Early Social Isolation In Macaca Mulatta: Changes In Dopamine Receptor Function Following Apomorphine Challenge, Mark H. Lewis, John P. Gluck, Tom L. Beauchamp, Michael F. Keresztury, Richard B. Mailman
Long-Term Effects Of Early Social Isolation In Macaca Mulatta: Changes In Dopamine Receptor Function Following Apomorphine Challenge, Mark H. Lewis, John P. Gluck, Tom L. Beauchamp, Michael F. Keresztury, Richard B. Mailman
Experimentation Collection
The hypothesis that early social isolation results in long-term alterations in dopamine receptor sensitivity was tested using older adult rhesus monkeys. Isolated and control monkeys were challenged with apomorphine (0.1 and 0.3 mg/kg), and the drug effects on spontaneous blink rate, stereotyped behavior, and self-injurious behavior were quantified using observational measures. Monoamine metabolites were quantified from cisternal CSF by HPLC-EC, prior to pharmacological challenge. Isolated and control monkeys did not differ in CSF concentrations of HVA, 5-HIAA, or MHPG. At the higher dose, apomorphine significantly increased the rate of blinking, the occurrence of whole-body stereotypies, and the intensity of stereotyped …
Alternatives To And Reduction Of Animal Use In Biomedical Research, Education And Testing, John M. Frazier, Alan M. Goldberg
Alternatives To And Reduction Of Animal Use In Biomedical Research, Education And Testing, John M. Frazier, Alan M. Goldberg
Experimentation Collection
Biomedical endeavours can be divided into three major categories: research, education, and testing. Within the context of each of these categories, activities involving whole animals have made major contributions and will continue to do so in the future. However, with technological developments in the areas of biotechnology and computers, new methods are already reducing the use of whole animals in certain areas. This article discusses the general tissues of alternatives and then focuses on the development of new approaches to toxicity testing.

Understanding Dogs Through Kinesthetic Empathy, Social Construction, And History, Kenneth J. Shapiro
Sentience Collection
The term, "come into animal presence," she takes from the title of a Denise Levertov poem. The poem, which reads, in part, "What joy when the insouciant armadillo glances at us and doesn't quicken his trotting across the track into the palm bush. What is this joy?" This joy is the possibility of our being in the presence of animals for "(t)he armadillo has some intention to pursue in the palm forest." This joy, to which I invite you here, consists in dwelling in that presence, in inhabiting that intention, that armored but guileless world of the armadillo. I will …
