    Area of Science:

    • Cognitive science
    • Primate behavior
    • Animal cognition

    Background:

    • Understanding non-human primate cognitive abilities is crucial for evolutionary studies.
    • Assessing chimpanzee (Pan troglodytes) cognitive skills using human-comparable tasks provides valuable insights.

    Purpose of the Study:

    • To evaluate a language-trained chimpanzee's capacity for same-similar-different judgments.
    • To investigate cognitive performance in chimpanzees using a controlled, economical testing format.

    Main Methods:

    • Administered paper-marking tests to a chimpanzee named Sarah.
    • Utilized tests modeled after human cognitive assessments.
    • Presented visual stimuli including familiar objects and novel alphabetic characters.

    Main Results:

    • Sarah successfully performed same-similar-different judgments on familiar object pictures.
    • The chimpanzee also demonstrated satisfactory performance on same-different judgments of novel alphabetic characters.
    • A consistent superiority in 'same' judgments was observed throughout the tests.

    Conclusions:

    • Language-trained chimpanzees can exhibit complex cognitive abilities, including abstract judgments.
    • The study validates the use of simplified, human-like tests for assessing primate cognition.
    • Sarah's performance suggests advanced comparative judgment capabilities in chimpanzees.
