How well do classifiers trained on visual activity actually transfer to non-visual reactivation?

#Decoding studies often rely on training in one (visual) condition and applying it to another (e.g. rest-reactivation). However: How well does this work? Show us what makes it work and win up to 1000$!

preprint alert 🚨
1/ Can we accurately detect sequential replay in humans using Temporally Delayed Linear Modelling (#TDLM)? In our recent study, we could not find any replay and decided to dig deeper by running a hybrid simulation with surprising results. Link to preprint & details below 👇

How Transparent and Reproducible Are Studies That Use Animal Models of Opioid Addiction? This study assessed transparency, reproducibility and bias minimization practices in animal models of opioid addiction research from 2019 to 2023. Key indices included analysis script sharing, prereg...

Alarming results in our new metascience article. NO cases of study preregistration and NO cases where authors shared their analysis code, across all 255 articles we found using animal models of opioid addiction from 2019-2023 onlinelibrary.wiley.com/doi/full/10....

Proud to share this new meta-science article—our analysis of 255 preclinical opioid addiction studies highlights a pressing need for better transparency and reproducibility. Big thanks to Justine Blackwell and @alexh.bsky.social – it was an honor working with you on this project! :)

I can highly recommend this opportunity for postdocs in cognitive neuroscience 👇

New preprint on "Attitudes Toward Open Science Practices"!

We asked 596 German psychologists about their worries and hopes towards open science practices!

ECRs reported more worries AND more fears, but the more you use OS the less worries and the more hopes you have.

Prestigious EU funding: ERC grant goes to Gordon Feld Dr. Gordon Feld has been awarded the ERC Consolidator Grant, which is endowed with around two million euros, for his research into memory processing during sleep using state-of-the-art imaging.

I am very honored to receive one of this years ERC Consolidator Grants!!! #ERCCoG

New findings of disappointing rates of methodological rigor and transparency! 😐

We coded all 255 papers we found on animal models of opioid addiction published between 2019 and 2023.

Rates of bias minimization practices and sample size calculations were.. unsatisfactory.

Yes, certainly! For the replication part, the hypotheses mainly concern behavioral findings and only one hypothesis is about the sleep EEG. We will upload the hypotheses soon. You can also team up with another person with EEG experience if you like. Let me know if you have any more questions :)

Thank you Juli! 🙏

RETRACTED: A Perception Study for Unit Charts in the Context of Large-Magnitude Data Representation Unit charts are a common type of chart for visualizing scientific data. A unit chart is a chart used to communicate quantities of things by making the number of symbols on the chart proportional to th...

An article about data visualization was retracted 1.5 years after I pointed out errors.

The notice says that "concerns were raised".

I spend dozens of hours contacting authors and editors, reproducing analyses, and following up on ignored emails.

But I'm not mentioned in the retraction notice.

Zoom on section b) of a figure displaying the experimental procedure. Julia can be seen modeling a participant in VR and in the desktop screen experiment.

Lastly, I’m really grateful for my colleagues of the SceneGrammarLab who made this study happen and allowed me to include photographs of myself in a figure. Look mom, I’m a model in a scientific paper! 💁‍♀️ 4/4

We also compared the procedure between both VR and 3D desktop screen settings and found only slight differences. This indicates that the screen setup could elicit comparable behavior as in VR. More research is needed to dive into the nuances and underlying processes 3/4

In line with our expectations, limited visual input did not impact or even benefited incidental memory of encountered objects. Moreover, spatial memory of scenes only seen with a flashlight was overall just as good as memory of illuminated scenes! 2/4

The third and last study of my PhD is now published! We limited visual input during visual search by using a naturalistic digital flashlight similar to classic contingent window paradigms, and measured effects on incidental memory. 1/4

Again, we have four(!) new positions here in psychology at the University of Sydney.
Like N. American tenure-track, but easier to get "tenure" (become permanent). Let me know of any questions! usyd.wd3.myworkdayjobs.com/USYD_EXTERNA... photo: Alex Holcombe

Thank you Alex! Means a lot :)

Thank you Lisa! ☺️

As a psychologist I don’t know about sociology, but it certainly is a question of interest in psychology!
