Mice and humans are equally skilled at assessing odds

We mentioned previously that our online course, ‘Basic Principles of Rodent Surgery,’ has been approved by the American Association of Veterinary State Boards (AAVSB) Registry of Approved Continuing Education (RACE) committee for 5 Continuing Education Credits for veterinarians and veterinary technicians and by the Director of the Professional Development of the American Association of Laboratory Animal Science (AALAS) for 5 AALAS Continuing Education Units (CEU).
We are also pleased to announce that the Canadian Association for Laboratory Animal Science (CALAS) approved this course, ‘Basic Principles of Rodent Surgery,’ for 3 CALAS Continuing Education Units (CEU). As usual, if you participate in the ‘interactive’ course, you should keep track of your participation hours and submit this number for your CEU.
Fuat Balci, David Freestone, and Charles R. Gallistel of Rutgers University report that
mice and humans are as equally proficient when faced with the task of learning which location is the best place to obtain a reward:
and mouse subjects tried to anticipate at which of 2 locations a reward would
appear. On a randomly scheduled fraction of the trials, it appeared with a
short latency at one location; on the complementary fraction, it appeared after
a longer latency at the other location. Subjects of both species accurately
assessed the exogenous uncertainty (the probability of a short versus a long
trial) and the endogenous uncertainty (from the scalar variability in their
estimates of an elapsed duration) to compute the optimal target latency for a
switch from the short- to the long-latency location.
