New paper from @soundbrainlab research asst. prof. Jacie McHaney along with V Cancel, V Milne, C Palmer & A Parthasarathy:
We analyzed 48000 patient records from UPMC clinics & found that Words in Noise, QuickSIN & Random Dichotic Digits Task can serve as a screener for Auditory Processing Disorder testing referrals.
And don't miss the open invitation for submissions to a special issue of Brain and Language:

Submission deadline is October 1: https://www.sciencedirect.com/journal/brain-and-language/about/call-for-papers
Chicago friends: Join us for our upcoming mini-symposium!
Speech processing in challenging listening environments: Towards a multi-dimensional framework
We aim to bring together investigators with broad interests in speech processing and perception difficulties to foster discussions addressing speech processing in noisy listening environments.

“Sensory and Cognitive Factors Underlying Self-Perceived Listening Difficulties in Adults with Normal Hearing Thresholds”
My paper with Yafit Gabay and Lori Holt is online now in Psychological Science!
Impaired and spared auditory category learning in developmental dyslexia
Open Access: https://doi.org/10.1177/09567976231151581
Individuals with dyslexia were selectively impaired in learning auditory categories that rely on procedural learning. Rule-based learning was completely spared.
Our results support a view of dyslexia as stemming from a general procedural learning deficit that affects nonspeech and speech learning.
Last talk of the session: Jacie McHaney @soundbrainlab : "Deficits in Sensory Decision-Making Underlie Self-Perceived Hearing Difficulties"
Looked at self-perceived listening difficulties (SSQ). Do people with listening difficulty differ in their sensory decision processes? Had people do a phoneme categorization task (quiet or noise).
Drift diffusion model on RTs for the phoneme task, giving evidence accumulation rate and decision threshold. Decision threshold does not change as a function of SNR.
Generally people have lower accumulation rates at less favorable SNRs. Slope of this (across SNR) relates to self perceived difficulty.
EEG study looking at neural tracking of acoustic and linguistic information in continuous speech (audiobook of Alice in Wonderland). Those with more self perceived difficulties didn't differ on tracking of acoustics (acoustic model).
For language processing, split apart sublexical, word, and sentence information. No differences in tracking for sublexical and word-level...but listeners with more self-perceived difficulty showed increased tracking for sentence level information. Compensation?
I really liked this linking of self-reported difficulties to objective in-lab measures. 💯
Happy Monday from #AROMWM! I am going to try to do a better job tooting from the conference today, in part because I was talking up Mastodon to a group of trainees yesterday. Will try my very best to keep the toots unlisted so as not to clog your feed (unless you follow me, in which case, you asked for it).
