Advantages and artifacts of high-speed OLED monitors for vision, eye-tracking, and EEG research - Behavior Research Methods

The recent introduction of organic light-emitting diode (OLED) monitors with refresh rates of 240 Hz or more opens new possibilities for their use as precise stimulation devices in vision research, ex...

[6] Again, it's important to say that these OLEDs are great, especially for fast and time-critical paradigms, but this is a new weakness we discovered that may affect certain slow paradigms.

[5] So the effect is not large, but could be critical for some paradigms in which high-contrast stimuli are shown for long durations and technical afterimages would be critical, like in adaptation paradigms. For more details, see the paper.

[4] In the figure (B) above, you see how the black checks of a checkerboard remain cooler than the white checks, even 20 sec later. The top panel (A) shows how a gray stimulus shown after a high-contrast black/white stimulus still differs in luminance (by about 1-2 cd/m^2) a minute later.

[3] We used thermal imaging to illustrate this problem: When you show bright stimuli for long durations (i.e., seconds), the OLED's pixels heat up locally. This warming then causes *subsequent* stimuli to be shown brighter at these locations. A small and slow, but devious form of image persistence!

[2] Overall, our tests show that high-speed OLEDs (now also available at 480 Hz) are fantastic for all time-critical, fast paradigms. However, in additional tests, we also found a previously unreported problem with OLEDs monitors in slow paradigms: 🔥🧊Localized temperature-luminance interactions 🔥🧊

Everyday visual experience tunes neural processing. Using fixation-related EEG, this new work shows how the N1 preview benefit depends on Chinese readers' prior experience with left-to-right vs. up-down reading. @umaurer.bsky.social www.authorea.com/doi/full/10....

This was not the case. Instead, results suggest that both magno- and parvo-biased information contributes to early, left-lateralized neural processes underlying visual word recognition. (2/2) Available in Neurobiology of Language: direct.mit.edu/nol/article-... @umaurer.bsky.social

Happy to be a collaborator on this new work by first-author Xin Huang from Urs Maurer's lab. In two combined eye-tracking/EEG experiments, we asked whether rapidly processed magnocellular (M-pathway) information in parafoveal vision plays a special role for word recognition in natural reading. (1/2)

The figure shows exemplary stimuli in experiments 1 and 2, that were biased for M- vs. P-pathway processing by spatial filtering (exp 1) or by isoluminance (exp 2).

Together with recent work by @olaf.dimigen.de on using RIFT with a monitor setup, as well as our own new preprint on using a monitor setup to track attention (www.biorxiv.org/content/10.1...), RIFT is now a lot more accessible both in terms of available recommendations and materials.

Yes, sure, also significant, but wouldn't you agree that lateralization still looks pretty weak (cf. Fig. 8)? But midline periphery (similar to our -12°) is also among weakest signal locations (at least if stimuli not scaled w/ cortical magnif.), so it's probably also a SNR issue in our data.

1) May seem surprising, but very much in line with MEG. See Figs 6 & 8 in Minarik et al., 2023, NeuroImage who mapped 15 VF locations. 2) The pilot described here was run with DC-EOG, but without ET; that's part of an ongoing follow-up

Our small pilot study shows RIFT works with an affordable 480 Hz OLED monitor & EEG: ✅ Reliable timing ✅ Robust tagging at 60 & 64 Hz to barely visible flicker ✅ Even weak peripheral responses We hope this opens the door to RIFT studies by more labs. (with Ioana Badea, Iarina Simon & Mark M. Span)

Instead of listing my publications, as the year draws to an end, I want to shine the spotlight on the commonplace assumption that productivity must always increase. Good research is disruptive and thinking time is central to high quality scholarship and necessary for disruptive research.

Hi Martin, the preprint refers to "Supporting Information" that seems to be not in the document. Is the full version available somewhere?

Are you looking for a precise monitor for vision science, eye-tracking, or EEG? In a new preprint (w/ Arne Stein), we tested a new type of display with excellent performance in time-critical experiments: "High-speed" (240 Hz) OLED monitors. All details here: www.biorxiv.org/content/10.1...
