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

We are the *Laboratoire des Systèmes Perceptifs*, a research unit located at the Ecole Normale Supérieure in Paris and attached to @cnrs. We are interested in #visual and #auditory perception, from behavioural, computational, and neural perspectives. #intro #introduction

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

To all scientists out there: I'd like to have your insight on a terminology issue in my field (#psychology #psychophysics).
The problem is the following: we have a type of experiment that is called a "forced-choice task". This name was chosen very early on (in the 60's). However it turns out to be very confusing as many researchers in the field believe that it refers to any experiment where participants are "forced to choose" between predefined answers. [1/2]

I had two side gigs in grad school: Converting figures from old journals to vector format, and making PCBs for various labs on campus. The last one is really odd for a psychologist now that I think of it, but electronics and machining are surprisingly useful skills to have as a psychophysics researcher

Dear editors of #DiamondOpenAccess journals,

I'm more than available as a reviewer for the topics of #EEG #Decision #psychophysics #chronometry #EMG

I would also be ready to do public post-print reviews for initiatives such as Open European Europe.

Psychophysics moment: I was making kebab and there was leftover seasoning in the packet, I was considering to add after I already blending it. But, my mind went: "Don't bother, adding it will likely be below JND for spiciness on an already elevated noise floor due to the green chilies."

Choice enhances touch pleasantness
Gorman et al., 2024 AP&P

"Before and during touching, pupillometry was used to measure the level of arousal. ... Regardless of how relevant it is to the actual tactile stimulus, allowing one to choose may positively enhance a person’s perception of the physical contact they receive."

Application of JNDs to meta-science. Very sensible!

"For example, in clinical settings researchers may specify this smallest effect size of interest as the smallest difference in a health condition that patients themselves notice...this practice has been used at least since the advent of psychophysics in the second half of the 19th century"

These are photos of a machine I (mostly) designed and built to study depth perception in physical environments

I wonder if my undergrad thesis ever got a follow up. It was a study to characterize the noise floor of brain circuits responsible for the perception of lighting direction in 3D scenes (Dr. Murray's lab at the CVR in 2008)

Anyone out there familiar with recent developments in this topic?

The Centre for Vision Research (CVR) at York University is hosting their annual 'CVR-VISTA Vision Science Summer School' program for undergraduates considering graduate studies in vision science

I attended it back in 2009 and it was well worth the experience, more info here:

Something cool I came across in the hardware lab. A BBTK that was gifted to us here a while back. This one is a bit old and uses a parallel interface. I'm considering building an interface for its sensor modules that can hook up to the oscilloscope for timing assessments

The circuitry in the control unit is (almost) all 7400 series chips

How well can we measure, map, decode, and interpret brain activity? It depends on lots of factors. Dr. @russpoldrack explains in four short videos:

1. Measuring Brain Function
2. Mapping Mind to Brain
3. Brain Decoding
4. Interpreting Human Neuroscience Data

https://philosophyofbrains.com/2023/12/01/four-videos-about-neurometrics-and-brain-data-dr-russ-poldrack.aspx

This is the 6th of 7 sets of videos from “A Beginner’s Guide To Neural Mechanisms”.
