New paper is out! Thanks to the amazing team @mijowolff, @veera_ruusk & @elkanakyurek. Ever wondered how a task-irrelevant impulse reveals active/silent WM representations? This paper has the answer! 1/6 https://t.co/jOpd9PLbm6

From the findings, we concluded that the presentation of impulse indeed perturbs active/silent networks on top of its global benefits on EEG! 5/6

This finding clarifies the current debate of whether impulse only benefits SNR of the EEG. Indeed, we also observed a benefit on SNR along with other global measures after impulse perturbation with no difference between conditions. 4/6

An irrelevant feature matching impulse targeted mnemonic networks better than a mismatching impulse after the impulse onset. 3/6

We designed two impulses in which a task-irrelevant feature matched or mismatched with the memory item. Following the impulse perturbation, we decoded target orientations from EEG. 2/6

8⃣/8⃣ Stay tuned for more as we continue to explore how ART can deepen our understanding of auditory working memory and whether auditory and visual systems share general memory constraints or differ in key ways! 🌐 #WorkingMemory #CognitiveScience #AuditoryResearch

7⃣/8⃣ We also found strong correlations between ART and other auditory memory tasks, confirming that ART truly taps into auditory-specific memory resources 🎯. Exciting potential for future cross-modal research!

6⃣/8⃣ What does this mean for working memory? 🤔 Our findings suggest common constraints in how visual and auditory memories work, bridging a gap in working memory research between different sensory modalities 🌉.

5⃣/8⃣ Key finding #2: ART provides a quantifiable measure of how errors distribute in auditory tasks, allowing us to apply computational models, like the mixture model, which have traditionally been used in visual memory 🧠🔍.

4⃣/8⃣ Key finding #1: 🧩 Auditory memory shows similar set-size effects as visual memory! We observed increased errors when participants had to remember 2 tones instead of 1 – more evidence that memory load affects performance across modalities 📊.

3⃣/8⃣ ART allows us to measure memory in a continuous, bias-free way, similar to popular visual reproduction tasks, but tailored for sound! Shepard tones create the illusion of infinite rising or falling tones, making them perfect for this purpose 🔄🎶.

2⃣/8⃣ What is a Shepard tone? It's an auditory illusion that sounds like a tone is endlessly rising or falling without ever changing pitch height 🎶🔄. If you’ve ever played Mario 64's endless stairs, you've experienced it! Check it out here: https://t.co/10soXoO5c1

1⃣/8⃣ Working memory research has long been dominated by visual tasks. But what about auditory memory? Can existing models apply across domains? To address this, we developed ART, using Shepard tones in a 360° auditory circular space 🎧.
