The path of the righteous: Using mouse movements to understand fraud decisions in real time
Dec 2022, phys.org
The team explored whether online fraudsters can be distinguished from honest users on the basis of their mouse movements, so-called "trace data," i.e., real-time data like mouse movements or click-streams. "We have already been working on trace data and consumer behavior for ten years,"Results show that, on average, those participants who gave fraudulent responses were much slower and had more deviations with their mouse movements than the honest users.

Deep learning algorithm can hear alcohol in voice
Jan 2023, phys.org
You know we're really just here for the Alcohol Language Corpus, where linguistic researchers in Germany convinced 162 men and women to get drunk and talk into a tape recorder.
And please let us not forget that this is in fact a sub-language called Drunken John. (But here is one of those moments when you're sure that either the internet, or the search algorithms, must be broken -- try searching for this and you'll find not a single instance, like it doesn't even exist.)
Audio-based Deep Learning Algorithm to Identify Alcohol Inebriation (ADLAIA) can determine an individual's intoxication status based on a 12-second recording of their speech.

Since prompts are all the rage these days, here:
- 002 Please speak to the experimenter: Talk about one of your vacations.
- 003 Please read as soon as possible: Messwechsel, Wachsmaske, Wachsmaske, Messwechsel (change of measurement, wax mask, wax mask, change of measurement)
- 014 Please answer the following question: What was the nicest present you received so far
- 016 Bitte so schnell wie möglich lesen: Die Köchin mit dem Tupfenkopftuch kocht Karpfen in dem Kupferkochtopf. (The cook with the polka dot headscarf cooks carp in the copper saucepan)

Neural prosthesis uses brain activity to decode speech
Jan 2023, phys.org
Machine learning model that can predict the word about to be uttered by a subject, based on their neural activity recorded with a small set of minimally invasive electrodes.
"About" to -- this is called "imaginary speech"

DOI: 10.1088/1741-2552/aca1e1
FYI: While ECoG provides higher density coverage over a limited cortical region (typically unilateral), sEEG provides sparser coverage spanning more, bilateral brain regions including deeper structures (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7056827). Unlike ECoG, electrodes for sEEG can be implanted without a full craniotomy via a drill hole in the skull. (https://medicalxpress.com/news/2023-01-neural-prosthesis-brain-decode-speech.html)
