Dr. David P. Beran, Dr. David
A. Washburn, and Dr. Daniel
L. Gulledge are psychologists
known for their research on
mathematical abilities in
animals, particularly in non-
human primates. Their work
has contributed to our understanding of the
cognitive capacities of animals, including their
ability to perform various mathematical tasks. Here
are some key aspects of their research:1. **Dr. David P. Beran**:─Dr. David P. Beran is a cognitive psychologist who
has conducted extensive research on the cognitive
abilities of non-human primates, particularly
chimpanzees and capuchin monkeys.─His research has explored various aspects of
numerical cognition in these animals, including
their understanding of numerical concepts such as
quantity, ordinality (order), and cardinality
(counting).─Beran's studies have involved tasks that require
monkeys to make choices based on numerical
information, such as selecting a larger quantity of
food items. His research has shown that monkeys
can discriminate between different quantities and
even perform simple addition and subtraction
tasks.2. **Dr. David A. Washburn**:─Dr. David A. Washburn is a comparativestudies on mathematical abilities in animals,
