I am part of this introductory level workshop that aims to bridge phenomenology and cogsci. The plan is to discuss ways in which the structure of experience can aid cogsci research.
Join us in Hyderabad! RTs appreciated ✌️

Excited to share a new preprint where we conduct a resource-rational analysis of planning in a large-scale data set of online chess games! From a great team including @evanrussek @miouantoinette @SagivYotam @weijima01 and @cocosci_lab.

new paper. During learning, why does it help to practice easy examples before hard ones? We provide a theory, based on deep learning models. TL;DR - curricula help with unlearning rather than learning. arxiv.org/abs/2611.04565. Led by @RubruckJirko and Alice Zhang, with @SaxeLab

i completed the first year of my CS phd, and have compiled a guide with advice from me + my mentors that made my first year so much easier.
preview in 🧵, but the good stuff (i.e. how to operationalize the advice!) is in the blog

3/ Then publish it with your own consent form, recruit with single-use links, watch sessions come in live, and pay participants without leaving the platform.
Currently UPI and bank transfer, so India for now. International payouts next.

2/ Describe a study in plain language, an LLM drafts the jsPsych code. It opens in a full editor and stays standard jsPsych — editable, exportable, no lock-in.

1/ AI has taken care of most of the coding. It hasn't touched the rest of running a study: hosting, recruitment, paying participants, monitoring, analysis. Still a different platform for each.
We built VibeMyExpt to put it in one place

Keynotes delivered by Dr. Sidharth Ranjan (IIT Jodhpur), Dr. Sabiha Hashami (IIT Goa), Dr. Reenu Punnoose (IIT Palakkad), Dr. Ashwini Vaidya (IIT Delhi) and Dr. Amitash Ojha (IIT Jammu) covered topics in sentence processing, sociolinguistics, LLMs & linguistic metaphors.

Dr. Himanshu Yadav (IIT Kanpur), led the Modeling track on Bayesian modeling while the Experimental track, jointly led by Dr. Apurva Apurva (IIM Jammu) & Dr. Samar Husain (IIT Delhi), provided hands-on training in statistical analysis using R & experimental design basics.

The 4th workshop on Experimental and Empirical methods in Linguistics (EEL 2026) was organised by the Department of Cognitive Science, IIT Kanpur from 1st-5th July 2026. The workshop saw participation from graduate students & early career researchers from varied backgrounds.

How do other animals experience time? It's been a pleasure to work with @ishan276 and @anilkseth on a paper exploring how temporal illusions and other experimental strategies can shed light on this. It's out today!
ALT A figure highlighting several ways of exploring how animals experience time: apparent motion, change blindness, continuity illusions, attentional blink, perceptual rivalries, the flash lag illusion, the peripheral drift illusion.

A lot of people have suggested over the centuries that ecosystems might have some degree of cognition. What would that look like? Could there be recognizable memory phenomena on the scale of population dynamics? Here's a #preprint where amazing high-school student @asamanta42, @HananelHazan, and I use a model system - in silico predator-prey dynamics - and analyze the possibility of several kinds of learning:
arxiv.org/abs/2605.30109
(the basics are kind of like thoughtforms.life/but-where-…, but some very cool new stuff here, including the interesting and unique pattern of learning-compatible values in the parameter space).

New Annual Review with @nathanieldaw. We argue that the planning machinery of the brain is mostly used for learning from simulated experience, and that thinking prospectively at decision time is just one special case of this more general process.

EEL 2026 will feature two parallel tracks:
(i) Experimental Track: learn experiment design and statistical analysis with R.
(ii) Modeling Track: learn Bayesian data analysis and cognitive modeling.

For Pokémon’s 30th anniversary, @Nature spoke to scientists from around the world about how their work has been shaped by playing Pokémon games, watching animated TV series and films and trading cards in school playgrounds. go.nature.com/4rIM2Db

👉 In this trial (RT = 458 ms), how should we count fixations and compute total fixation duration on the target image?
What’s the most correct way for these three cases? Curious how others handle this in their analyses!
