Formal study on how over reliance on LLMs is harmful for cognitive abilities for students.

> ""Over four months, LLM users consistently underperformed at neural, linguistic, and behavioral levels. These results raise concerns about the long-term educational implications of LLM reliance and underscore the need for deeper inquiry into AI's role in learning.""

"Artificial intelligence is already killing off important parts of the human experience. But one of its most consequential murders—so far—is the demise of a longstanding rite of passage for students worldwide: an attempt to synthesize complex information and condense it into compelling analytical prose."

Our colleague Cedric Boeckx picked up this piece by Sam Mehr 'on the special(ized) character of human auditory perception underlying musicality; contains very good points re: cross-species (dis)analogies (e.g. why bird ‘song’ may be a misnomer)'

As Mehr puts it: fundamental specializations are for music perception in humans, namely, the hierarchical processing of pitch and rhythm
or, how our minds turn vibrating air into music'

A mouse study found that lactate, whether produced by exercise or administered exogenously, reduces cognitive impairment. This provides a potential explanation for the effects of exercise in mitigating the effects of Alzheimer's disease.

BioMed CentralLactate links exercise to synaptic protection and cognitive enhancement in Alzheimer’s disease models - BMC MedicineBackground Physical exercise is known to promote cognitive resilience in aging and Alzheimer’s disease (AD), but the underlying mechanisms remain incompletely understood. Lactate, a metabolic byproduct elevated during exercise, has recently emerged as a potential neuromodulator of brain function. Methods Three AD-like mouse models (SAMP8, Aβ1-42 injection, and 5xFAD) were used to evaluate the effects of treadmill exercise on cognitive function and synaptic plasticity. Serum lactate levels were assessed, and sodium L-lactate (NaLA) was administered to determine its neuroprotective effects. Transcriptomic analysis was performed on hippocampal tissue to explore lactate-regulated pathways. Lactate transport was pharmacologically inhibited using 4-CIN for mechanistic validation. Results Treadmill exercise significantly improved cognitive performance and increased synapse-associated protein expression in AD models. Exercise elevated serum lactate levels, and exogenous NaLA administration recapitulated the cognitive and synaptic benefits of exercise. Transcriptomic profiling revealed enrichment of genes involved in axon guidance and synaptic organization, including upregulation of multiple Eph receptor family genes. α-cyano-4-hydroxycinnamic acid (4-CIN) administration abolished the exercise-induced neuroprotective effects, confirming the essential role of lactate transport in mediating these benefits. Conclusions This study identifies lactate as a critical mediator linking exercise to enhanced synaptic function and cognitive improvement in AD-like models, providing mechanistic insights and highlighting lactate metabolism as a potential therapeutic target for AD.

Combatting the Effects of #CyberPsychosis - STUDY: “Humanity is currently facing an existential crisis about the nature of #truth and #reality driven by the availability of information online which overloads and overwhelms our cognitive capabilities, which we call Cyber-Psychosis. The results of this Cyber-Psychosis include the decline of critical thinking coupled with deceptive influences on the Internet which have become so prolific that they are challenging our ability to form a shared understanding of reality in either the digital or physical world. Fundamental to mending our fractured digital universe is establishing the ability to know where a digital object (i.e. a piece of information like text, audio, or video) came from, whether it was modified, what it is derived from, where it has been circulated, and what (if any) lifetime that information should have.” #internet #Enshittification #MentalHealth #cognition #InformationOverload #Study

arXiv.orgCombating the Effects of Cyber-Psychosis: Using Object Security to Facilitate Critical ThinkingHumanity is currently facing an existential crisis about the nature of truth and reality driven by the availability of information online which overloads and overwhelms our cognitive capabilities, which we call Cyber-Psychosis. The results of this Cyber-Psychosis include the decline of critical thinking coupled with deceptive influences on the Internet which have become so prolific that they are challenging our ability to form a shared understanding of reality in either the digital or physical world. Fundamental to mending our fractured digital universe is establishing the ability to know where a digital object (i.e. a piece of information like text, audio, or video) came from, whether it was modified, what it is derived from, where it has been circulated, and what (if any) lifetime that information should have. Furthermore, we argue that on-by-default object security for genuine objects will provide the necessary grounding to support critical thinking and rational online behavior, even with the ubiquity of deceptive content. To this end, we propose that the Internet needs an object security service layer. This proposition may not be as distant as it may first seem. Through an examination of several venerable (and new) protocols, we show how pieces of this problem have already been addressed. While interdisciplinary research will be key to properly crafting the architectural changes needed, here we propose an approach for how we can already use fallow protections to begin turning the tide of this emerging Cyber-Psychosis today!

"So what can we learn from them about the impact of technology on the ageing brain? A comprehensive new study ... provides important answers. Published in Nature Human Behaviour, it found no supporting evidence for the 'digital dementia' hypothesis. In fact, it found the use of computers, smartphones and the internet among people over 50 might actually be associated with lower rates of cognitive decline."
