Eye tracking in nonhuman primates provides insights about decision making, emotion recognition, attention, and social behavior. Eye tracking offers a possibility to assess humans and nonhuman primates using the same or similar conditions, which provides a translational opportunity to bridge the gap between basic and clinical investigations. Our noninvasive and restraint-free eye tracking technology allows researchers to collect data in custom laboratory and natural settings while being supportive of the primate’s welfare.
Eye tracking opens research possibilities in:
- Cognitive neuroscience
- System neuroscience
- Clinical and translational neuroscience
- Behavioral psychology
- Cognitive psychology
What you can measure with eye tracking?
Pupil center corneal reflection (PCCR) is one of the most accurate and non-invasive ways to measure eye movements. Eye trackers using this technique typically deliver a data stream in real-time containing raw data, such as gaze origin, gaze point, and pupil diameter. The eye tracking solution and a dedicated application, like our software Tobii Pro Lab, can further process the data to draw valuable conclusions on a wide variety of cognitive processes in NHPs, including:
- Cognitive reasoning
- Face processing
- Social preference
Reliability in a range of settings
When conducting eye tracking research on nonhuman primates, it is important that your solutions ensure reliability across a variety of locations and scenarios. Whether you are conducting research in a controlled laboratory setting or in an animal enclosure like a zoo or sanctuary, Tobii has built a range of eye tracking solutions that deliver robust data without compromising freedom of movement or ease of use.
Screen / Lab
The visual stimuli are displayed on a screen, in a laboratory environment, using the screen-based eye trackers Tobii Pro Spectrum and Tobii Pro Lab.
Screen / Field
The visual stimuli are displayed on a screen in a zoo or a primate sanctuary using Tobii Pro Spectrum and Tobii Pro Lab.
Real scene / Lab
The subjects observe or interact with objects or stationary physical scenes in a laboratory environment, using Tobii Pro Spectrum and Tobii Pro Lab.
Screen-based eye tracker capturing gaze data at speeds up to 1200 Hz. This high-performance research system provides superior data quality and is designed for extensive research into behavior and eye movements – from fixation-based studies to micro-saccades.
Pro Lab is the eye tracking software designed for conducting experimental research with Tobii Pro hardware. The flexible platform guides and supports the researcher through the entire research workflow, from simple to complex experiments.
