Recently ran a prolific study asking ppts to describe images in <20 words. With 50 captions per person, we were able to pass each participant’s full text into Pangram. It detected 2 out of 200 with high confidence as fully AI, and about 6/7 others as borderline AI/human. FWIW :)

Happy and honored to receive the first ERC grant in Romanian psychology! In GENESIS, I will investigate how the mind redescribes complex statistical regularities into simpler, consciously accessible representations. Many thanks to everyone who supported me in this quest! #ERCStG @erc.europa.eu

Why are younger children so good at learning new skills? One reason may be that they are better at a fundamental cognitive mechanism: statistical learning. We followed the same children from age 7 to 14 and found that this learning gradually decreases as they grow older. doi.org/10.1038/s414...

While our findings offer convincing evidence for unconscious priming at the single-subject level based on proper statistical procedures, our study also emphasises the importance of providing clear instructions and sufficient training to appropriately assess awareness. 8/8

These findings suggest that implicit evaluations may be largely or entirely inaccessible to conscious awareness: benedekkurdi.com/files/Kurdi_.... Many open questions remain, including most importantly whether this is a weird case, or whether these non-introspective processes operate more generally.

Online Now: In defense of a distinction
dlvr.it
In defense of a distinction
Thirty years ago, Block proposed a hugely influential distinction between phenomenal (P) and access (A) consciousness [1,2]. A state is P-conscious if there is something it is like to be in it, and A-conscious if its content is available for reasoning, rational action guidance, and report. Block’s distinction is principally conceptual, but Block has since offered introspective, behavioral, and neuroscientific grounds for thinking that A-consciousness and P-consciousness actually dissociate. For instance, he has argued that iconic and fragile short-term memories are often P-conscious but not A-conscious; that ‘exclusion’ paradigms evidence contents which are P-conscious but not A-conscious; and that local recurrent processing in posterior regions realizes P-consciousness without the anterior activity required for A-consciousness [3–6].

Mind wandering enhances the brain’s ability to learn hidden patterns, new study suggests
Daydreaming is often viewed as a failure of attention, but new research suggests it serves a hidden purpose. Scientists have discovered that the temporary drop in self-control during mind wandering actually boosts the brain’s ability to unconsciously learn complex environmental patterns.

Online Now: The homogenizing effect of large language models on human expression and thought
dlvr.it
The homogenizing effect of large language models on human expression and thought
Cognitive diversity, reflected in variations of language, perspective, and reasoning, is essential to creativity and collective intelligence. This diversity is rich and grounded in culture, history, and individual experience. Yet, as large language models (LLMs) become deeply embedded in people’s lives, they risk standardizing language and reasoning. We synthesize evidence across linguistics, psychology, cognitive science, and computer science to show how LLMs reflect and reinforce dominant styles while marginalizing alternative voices and reasoning strategies. We examine how their design and widespread use contribute to this effect by mirroring patterns in their training data and amplifying convergence as all people increasingly rely on the same models across contexts. Unchecked, this homogenization risks flattening the cognitive landscapes that drive collective intelligence and adaptability.
