psychologist who has worked extensively with
rhesus monkeys and chimpanzees to investigate
their cognitive abilities.
─His research has covered a wide range of topics,
including numerical cognition. He has designed
experiments to assess monkeys' understanding of
numerical concepts, numerical discrimination, and
counting abilities.
─Washburn's studies have employed touch-screen
computer tasks in which monkeys interact with
numerical stimuli to reveal their numerical
knowledge and problem-solving abilities.
- Dr. Daniel L. Gulledge:
─Dr. Daniel L. Gulledge has collaborated with both
Dr. Beran and Dr. Washburn on various research
projects related to numerical cognition in primates.
─His work has contributed to our understanding of
how primates represent and manipulate numerical
information mentally.
─Gulledge's research, often conducted in controlled
laboratory settings, has revealed that primates can
engage in complex numerical tasks, such as
ordering numbers or matching quantities to
symbols.
