MattHappy Gustav Fechner day psychophysics people!
I didn't know that October 22 was "Fechner Day" (the founder of psychophysics)
If you don't know who Gustav Fechner is, you can read more about him here: https://en.wikipedia.org/wiki/Gustav_Fechner
Léo VarnetIf you're near Besançon and interested in auditory science or psychophysics, check out this upcoming series of talks at the FEMTO-ST Institute https://neuro-team-femto.github.io/revcor25/
I'll be giving one of them, looking forward to great discussions!

Worked on improving camera recordings in PsychoPy today. Some of the optimizations I made to movie player are now being applied to the camera interface with excellent results
I finally got to work on a prototype for the audio/visual synchronization tester I designed a few years back
This device is used to measure the lag between the presentation of a visual stimulus on screen and a sound that's associated with it
This design will be open sourced and uses widely available components
I bought loads of capacitors for work and I still don't have the right value for this project I'm starting :/
The project is a tone detector module for a device which measures audio/visual/input lag on computers used for psychophysics experiments. It also allows us to benchmark software techniques that correct for synchronization errors

Crossmodal correspondence of elevation/pitch and size/pitch is driven by real-world features https://link.springer.com/article/10.3758/s13414-024-02975-7 The vOICe sensory substitution uses pitch (tone frequency) to encode elevation; #crossmodal #multisensory #perception #psychophysics
Crossmodal correspondence of elevation/pitch and size/pitch is driven by real-world features - Attention, Perception, & Psychophysics
Crossmodal correspondences are consistent associations between sensory features from different modalities, with some theories suggesting they may either reflect environmental correlations or stem from innate neural structures. This study investigates this question by examining whether retinotopic or representational features of stimuli induce crossmodal congruency effects. Participants completed an auditory pitch discrimination task paired with visual stimuli varying in their sensory (retinotopic) or representational (scene integrated) nature, for both the elevation/pitch and size/pitch correspondences. Results show that only representational visual stimuli produced crossmodal congruency effects on pitch discrimination. These results support an environmental statistics hypothesis, suggesting crossmodal correspondences rely on real-world features rather than on sensory representations.
