A multi-lab replication effort (@eegmanylabs.bsky.social) of the contralateral delay activity (CDA) has just been published online! In brief, the set-size effect appears to be robustly observed, but CDA correlation with VWM capacity is not reliably strong. doi.org/10.1016/j.co...

Here's my previous post for summary and preprint link: bsky.app/profile/yong...

Yong Hoon Chung @yonghoonchung.bsky.social · 09/02/2026

This highlights the role of semantics in VWM, challenging models that treat WM as primarily perceptual with fixed limits. Using naturalistic stimuli with careful evaluations may enable us to probe the rich structure of VWM, offering a deeper understanding of how VWM is used in the real-world. 11/

010

Yong Hoon Chung @yonghoonchung.bsky.social · 09/02/2026

How can real objects enhance VWM? We hypothesize that semantic distinctiveness is the key: beyond visual features, real objects engage conceptual knowledge, yielding more distinctive and potentially stable memory representations, ultimately aiding performance. 10/

Yong Hoon Chung @yonghoonchung.bsky.social · 09/02/2026

Lastly, a large-sample (n=300) correlation analysis showed that subjective familiarity rating predicted memory performance for real objects, while colourfulness scaled with memory performance for counterfeit objects, despite both stimulus sets matched in colourfulness scores. 9/

100

Yong Hoon Chung @yonghoonchung.bsky.social · 09/02/2026

ERP pattern similarity analysis showed that encoding and remembering real objects resulted in earlier and more robust pattern stability than counterfeit objects. This may suggest that real objects result in quicker and more stable memory representations due to available visual-semantic templates. 8/

Yong Hoon Chung @yonghoonchung.bsky.social · 09/02/2026

CDA is one way to look at neural engagement. But this only captures an average amplitude over predefined time windows. Another way we can examine neural engagement is to look at how the patterns of neural activity dynamically change over time. 7/

110

Yong Hoon Chung @yonghoonchung.bsky.social · 09/02/2026

We also looked at underlying neural activities using EEG, specifically contralateral-delay-activity (CDA). The results showed increased neural engagement when remembering real than counterfeit objects, shown in both heightened and more spread-out lateralized ERP activities. 6/

Yong Hoon Chung @yonghoonchung.bsky.social · 09/02/2026

Strikingly, despite this match VWM performance improved only for real objects, not counterfeit ones. Counterfeit objects resulted in similar performance to fully scrambled shapes. 5/

100

Yong Hoon Chung @yonghoonchung.bsky.social · 09/02/2026

First, we tested whether these counterfeit objects are well matched in perceptual similarity with real objects. Using CNNs, we extracted visual features of each object and quantified similarities among them. This confirmed that counterfeit objects are indeed visually matched to real objects. 4/

Yong Hoon Chung @yonghoonchung.bsky.social · 09/02/2026

Here, we tackled this using “counterfeit objects” (Cooper et al., 2023): GAN-generated images that match real objects in visual properties but are novel and unrecognizable. 3/

Yong Hoon Chung @yonghoonchung.bsky.social · 09/02/2026

Oftentimes memory performance comparison is made across drastically different looking stimulus types such as real objects and colored circles or scrambled shapes. Specifically, real objects are visually more unique and discernible. Can these perceptual differences explain the memory benefit? 2/

New preprint with @SamJung @timbrady.bsky.social and @violastoermer.bsky.social: osf.io/preprints/ps.... Here we uncover what might be driving the “meaningfulness benefit” in visual working memory. Studies show that real objects are remembered better in VWM tasks than abstract stimuli. But why? 1/

Make it your New Year resolution to add a #workingmemory dataset to OpenWMData so that we can curate our field's precious data, start testing theories and benchmarking models across datasets, conduct secondary analyses and meta-research using the data itself, and help me feel like I'm, like, alive.

Has anyone attended any pre-data-collection poster sessions (i.e., poster sessions where people present their plans for experiments before data collection in order to get feedback when it's most useful) at conferences other than VSS?

Broadly, this suggests that the FFDE is relatively location-specific. Fun and quite shocking illusion to look at!

000

Yong Hoon Chung @yonghoonchung.bsky.social · 14/11/2025

Our results consistently showed that the illusion was significantly disrupted with location shifts of the faces. We also look at how the illusion develops over time, something that hasn't been looked closely before.

100

Yong Hoon Chung @yonghoonchung.bsky.social · 14/11/2025

FFDE is a fun illusion where peripherally presented faces start looking monstrous. Here we test whether this illusion can be transferred to new locations during the face streams. Importantly, we use joysticks so that people can continuously rate how weird the faces get, capturing the whole dynamics.

Today afternoon I’ll be presenting my poster at #vss2025 titled “Perceptual and conceptual contributions of the real-world object benefit in visual working memory: Is looking like an object good enough to enhance memory?” See you at Pavillion!

Yong Hoon Chung @yonghoonchung.bsky.social · 17/05/2025

Overall, our results add to the emerging evidence that meaningful and familiar stimuli can enhance visual working memory processes and also show that remembering meaningful stimuli and simple features share core active cognitive processes.

000

Yong Hoon Chung @yonghoonchung.bsky.social · 17/05/2025

Additionally, the meaningfulness benefits showed up even in the first five trials of the task in our results, showing how robust the effect is in visual working memory.

100

Yong Hoon Chung @yonghoonchung.bsky.social · 17/05/2025

We also find that the amount of working memory increase individuals get from using meaningful stimuli also correlates with fluid intelligence scores, suggesting a link between meaningfulness benefit and fluid intelligence abilities.

100

Yong Hoon Chung @yonghoonchung.bsky.social · 17/05/2025

In this paper we show that working memory performances for both real-world objects and colored circles reliably correlate with individual differences in fluid intelligence but not with crystallized intelligence measures.

Overall, our results show that working memory is shaped by the context at encoding. Meaningful context promotes stronger and more stable neural engagement during encoding and maintenance. This indicates that working memory processes are flexible, even with respect to a single feature dimension. 8/8

010

Yong Hoon Chung @yonghoonchung.bsky.social · 30/04/2025

Interestingly, we also found a broad and large difference in non-lateralized ERP waveforms between the two conditions during both encoding and delay periods. While more research will be needed to fully understand this novel component, this appears to robustly distinguish the two types of stimuli. 7/

110

Yong Hoon Chung @yonghoonchung.bsky.social · 30/04/2025

We also examined how stable the neural activity patterns are over time by adopting a cross-temporal pattern similarity analysis. The results showed that neural stability arises more rapidly when remembering features of real-world objects. 6/

Yong Hoon Chung @yonghoonchung.bsky.social · 30/04/2025

Our results showed enlarged and more spread-out CDA when colors were encoded and remembered as parts of real-world objects, suggesting expansion in involvement of active working memory storage. 5/

Yong Hoon Chung @yonghoonchung.bsky.social · 30/04/2025

In the experiment, participants viewed and remembered colors of either intact real-world objects or scrambled objects. Critically, only colors were relevant features in the task and the identities of objects were not asked throughout the experiment. 4/

Yong Hoon Chung @yonghoonchung.bsky.social · 30/04/2025

Mainly, we are looking at CDA (contralateral delay activity), an ERP component during the maintenance period of visual working memory tasks well known to be correlated with engagement of active working memory storage. 3/
