Abstract
Identification of Sequence Learning in Rhesus Macaques through
Infrared Eye Tracking
By Termpanit Chalermpalanupap
Studies in both humans and monkeys have demonstrated that
eye-movements can be useful in the investigation of memory for
temporal sequences. For example, a study used non-invasive infrared
eye-tracking to observe eye movements while human infants watched
videos depicting a sequence of actions. The results suggested that
infants made a significant number of anticipatory looks with
repeated presentations. The present study aims to replicate this
finding in an animal model using Rhesus macaques. In Experiment 1,
3 monkeys were shown repetitions of video sequences while their eye
movements were tracked with an infrared camera. Eye-movements that
were anticipatory for objects that would move 3 steps in advance
and 1 step in advance were examined, along with the number of
eye-movements that were directed toward moving objects and
distracter (non-moving) objects. A comparison between the initial
viewing of the video and subsequent viewings revealed significant
differences in the percentages of anticipatory looks for both3- and
1- step intervals, as well as the ratio of moving to distracter
objects. In Experiment 2, the effects of familiarizing the monkeys
with the video objects on sequence learning were examined. The
monkeys performed a delayed match to sample (DMS) task, using the
video objects as stimuli, one day prior to being tested on the
video task. The results from Experiment 2 revealed that there was
no significant effect of the DMS pretreatment on sequence learning.
The analyses suggest that, similar to human infants, monkeys
demonstrate sequence learning as measured by anticipatory
eye-movements. Accordingly, this task could be used, along with
neurophysiological techniques, to investigate the neural correlates
of sequence learning.
