A novel Android app to evaluate and enhance auditory and tactile temporal thresholds

Area of Science:

• Neuroscience
• Psychology
• Human-Computer Interaction

Background:

• Temporal sensitivity is crucial for sensory processing.
• Deficits in temporal abilities are associated with various neurological conditions.
• Existing methods for assessing temporal sensitivity can be limited in accessibility.

Purpose of the Study:

• To introduce a novel Android application for monitoring and enhancing auditory and tactile temporal sensitivity.
• To evaluate the technical reliability and participant validation of the developed application.
• To investigate the potential of the app in improving temporal abilities through perceptual learning.

Main Methods:

• Developed an Android app to present auditory and vibratory stimuli for temporal tasks.
• Assessed app accuracy in stimulus production (onset, offset, duration).
• Utilized a Two-Alternative Forced-Choice (2AFC) task with 12 participants to evaluate auditory and tactile temporal sensitivity.

Main Results:

• The app accurately measured auditory and tactile temporal thresholds.
• Participants showed enhanced temporal abilities after four days of app-based training.
• The application demonstrated technical reliability and effectiveness in perceptual learning.

Conclusions:

• The novel Android app is a reliable tool for assessing auditory and tactile temporal sensitivity.
• The app can effectively enhance temporal abilities via perceptual learning.
• The app's accessibility makes it suitable for rehabilitation programs targeting sensory and temporal deficits.
