• Ivory added a new preprint on PsyArXiv, about concealed information detection with oculomotor measures in rapid serial visual presentation. Get it here.
• Psychophysiology accepted the ERP paper Gülşen and I wrote on in- and extrinsic factors in visual temporal integration! We found that even though the (intrinsic) passage of time and the (extrinsic) onset of stimuli similarly affect the tendency to integrate, the underlying neural pathways seem quite different.
• We put a new preprint on bioRxiv, on feature matching between impulse perturbation stimuli and memoranda in working memory. This rather cool little project was first-authored by Aytaç.
• What better time to read a new preprint on attentional scaling than summertime? Another fine manuscript that was spear-headed by Shuyao.
• An elevator-pitch-esque video about my work on the neural basis of working memory has popped up on YouTube. It’s in Dutch, but captions are available. You can watch it right here, too:
• Güven and Sophia got a new preprint out on bioRxiv about working memory for colors! Multivariate pattern analyses, impulse perturbation, and some intriguing findings… here.
• Joost and Sophia worked together on a cool paper about adaptive forgetting in working memory; you can find the preprint here.
• Another new preprint by Joost & Co, here. This is Joost’s BIG paper on the computational model of timing he developed. You were warned.
• Güven’s paper on revealing activated long-term memories with impulse perturbation was just accepted for publication in NeuroImage!
• In the latest Police and Science call, our project on concealed information detection was awarded an extension. Looking forward to continue this research line together with our partners at the Police!
