The FAPA – From Audiovisual Perception to Action: the processing of spatiotemporal components – project was developed by CCG, by its applied research domain PIU, between 2015 and 2017.
The final results of this project were presented at the 12th Bial Foundation Symposium, which took place between April 4 and 7, 2018, at the Casa do Médico in Porto.
The FAPA project aimed at studying the spatial and temporal resolution of the auditory and visual systems individually and collectively in a series of dynamic tasks. The main objective of the project was to see if, with static and moving stimuli, we are able to estimate correctly where the event is located in space and time.
Conclusions of the FAPA project
In short, as conclusions, we found out that we are able to:
- judge with a high performance the passage of a sound, even if not all the information on its trajectory is available, using different auditory cues depending on the difficulty of the task;
- locate static sounds in different spatial positions with greater precision in the plane of the ear and in the frontal plane, with a decrease in the magnitude of the error with training.
In a real-time gait synchronization task, it was found that synchronization in the condition where only auditory information was available did not differ from the condition in which auditory and visual information was available.
