Mixed-effects modellers, assemble!

Just dropped a (very niche) blog on the weird quirks that occur with uncorrelated random effects and the trifecta of packages: lme4, afex, and performance (in R).

If you're interested in the cognitive neuroscience of memory feel free to email me!

I do experimental psychology, brain imaging (fMRI and MEG) and a bit of modelling. Lab is doing stuff on forgetting, aging, schemas, and event boundaries, but we're not limited to that.

How to decide what to replicate or reproduce? We recommend priotizing studies with "high value" or unclear results, considering practical limits, watching for bias, and always communicate choices openly.

Another awesome video from Numberphile. I’m not going to spoil it, but I will say it is very relevant if you teach research methods (it not just statistical in a narrow sense) youtu.be/VwIKKBL4ldQ?...

Hi! Nice to virtually meet you! Here is the QR code to a PDF of the poster. Glad you found it interesting! If you have any questions or want more details, happy to chat about it! 🙂

Was meant to be presenting at #BACN25 on Thursday. Unfortunately, COVID has decided otherwise. My poster will still make an appearance though. Even better? It’s presented by @aidanhorner.bsky.social instead! Go check it out on Thursday along with other lab posters on narratives, objects and schema.

🚪🧠 Ever wondered if walking through doors really changes your memory? At #ESCOP25 today I’m at Board 19 showing how spatiotemporal boundaries impact recall in VR. Although time matters, it’s more to do with using it effectively!
This poster presents work that examines how spatiotemporal boundaries influence recall. Previous research suggests that such boundaries improve memory (Logie & Donaldson, 2021). It remains unclear, however, whether the benefit comes directly from the boundaries or from the post-encoding processes they permit, such as elaborative rehearsal. Across three experiments, participants studied words in a virtual environment under different conditions: (1) Non-segmented: continuous word presentation in a single room; (2) Segmented: a new room introduced every four words, creating spatiotemporal boundaries; (3) Non-segmented (time): continuous word presentation in one room, with structured pauses to match the timing of the segmented condition. In Experiment 3, the segmented condition was replaced by a non-segmented (task) condition, which used the same timing as the non-segmented (time) condition but filled the pauses with a 2-back task to prevent rehearsal. Findings were as follows: Experiments 1 and 2 showed better recall in the segmented and non-segmented (time) conditions compared to the non-segmented condition, with no difference between segmented and non-segmented (time). Experiment 3 found reduced recall when a task replaced the free period. However, it did not replicate the earlier benefit of non-segmented (time) over non-segmented. Overall, the results suggest that recall advantages observed in earlier work may be due to post-encoding processes rather than the boundaries themselves. The next experiment will test whether elaborative rehearsal or resource allocation during encoding better explains these effects by systematically varying the presence of free periods and tasks.

So happy to share our paper on the role of the hippocampus as a mismatch detector:
doi.org/10.1073/pnas...

We show that the hippocampus detects mismatches between ongoing experiences and episodic memories but not generalised schematic knowledge.

We make predictions based on general knowledge and/or specific memories. Different brain areas are active when these distinct predictions are violated – and hippocampus selectively responds to prediction errors based on episodic memory.

I’m about halfway through this update (first 11 tutorials are done). I think they’re a lot better. Using a consistent @easystats.github.io workflow throughout will - I think - massively reduce the cognitive load for students. Looking forward to road testing in autumn term.

Probably no-one except me uses my R tutorials in their teaching, but if you do, I'm re-writing them over the next 6-9 months. My goal is to streamline them based on 5 years of using them in class, but if you have (polite) requests/suggestsions let me have them. www.discovr.rocks/discovr/

{truffle} is an R package for teaching users to process data.

Semi-realistic psychological datasets with predetermined effects (via `truffles_` functions) are then hidden in common data processing headaches (via `dirt_` functions) for students to clean and analyze.
