Summary
This study introduces SPEED software for processing eye tracking data, aiding researchers in analyzing visual perception and cognitive processes. A pilot study found significant differences in reaction times and blinks during moral decision-making tasks.
Area of Science:
- Cognitive Neuroscience
- Ophthalmology
- Human-Computer Interaction
Background:
- Eye tracking is crucial for understanding visual perception and cognitive processes.
- Existing data processing methods can be complex and require coding expertise.
- Pupil Lab Neon is a common eye tracking hardware.
Purpose of the Study:
- To introduce SPEED (labScoc Processing and Extraction of Eye tracking Data), a novel Python-based software for processing Pupil Lab Neon eye tracking data.
- To enable researchers to extract features from eye tracking data without requiring coding skills.
- To investigate oculomotor correlates and autonomic predictors during moral decision-making.
Main Methods:
- Development of the SPEED software using Python for automated feature extraction.
- Conducting a pilot study with five healthy participants.
- Utilizing the Moral Decision-Making Task (MDMT) with personal and impersonal dilemma conditions.
- Recording and analyzing eye movements and blinks using Pupil Lab Neon.
Main Results:
- SPEED software successfully processes eye tracking data, simplifying feature extraction.
- Statistically significant differences were found in reaction times between personal and impersonal moral dilemmas.
- A significant difference in the number of blinks was observed during choices in the MDMT.
Conclusions:
- The SPEED software offers a user-friendly solution for eye tracking data analysis in research.
- Oculomotor measures, specifically reaction time and blink rate, are sensitive to the type of moral dilemma.
- Eye tracking provides valuable insights into cognitive processes underlying moral decision-making.
