Heavy multitaskers have reduced memory
People who frequently engage with multiple types of media at once performed worse on simple memory tasks, according to the last decade of research. However, it’s still too soon to determine cause and effect, says psychology Professor Anthony Wagner.

To Remember, the Brain Must Actively Forget | Quanta Magazine
Researchers find evidence that neural systems actively remove memories, suggesting that forgetting may be the default mode of the brain.

ChatGPT acts as a "cognitive crutch" that weakens memory, new research suggests
A recent experiment provides evidence that relying on artificial intelligence to study tends to reduce how much information students remember weeks later.

People are not friction
The Gell-Mann Amnesia Effect of AI is a pretty well documented phenomenon: The Gell-Mann amnesia effect is a cognitive bias describing the tendency of individuals to critically assess media reports in a domain they are knowledgeable about, yet continue to trust reporting in other areas despite recognizing similar potential inaccuracies.

Augmenting Long-term Memory
One day in the mid-1920s, a Moscow newspaper reporter named Solomon Shereshevsky entered the laboratory of the psychologist Alexander Luria. Shereshevsky's boss at the newspaper had noticed that Shereshevsky never needed to take any notes, but somehow still remembered all he was told, and had suggested he get his memory checked by an expert.

Excess Capacity Learning
We introduce a new framework for understanding how cognitive systems (e.g., humans) learn from experience, based on the concept of representational capacity—the relative amount of representational resources devoted to encoding past experiences. Most paradigms in cognitive science have operated under the assumption that these resources are constrained, forcing cognitive systems to compress rich and noisy experiences to effectively generalize to new situations. We leverage recent advances in computer science to outline the implications of learning with excess capacity, or applying even more representational resources than needed to perfectly memorize all the details of one’s past experiences. In particular, we review evidence suggesting that excess capacity systems can exhibit many of the characteristics of human learning, such as the simultaneous ability to memorize individual experiences and generalize knowledge to new situations. We define and differentiate between constrained (not enough), sufficient (just enough), and excess (more than enough to perfectly capture all the details of one’s past experiences) capacity. We derive empirical properties of learning in each of these capacity regimes, and compare these predictions to effects documented for human learning. We highlight the broad implications of this framework for advancing theoretical and empirical work across cognitive, clinical, and developmental psychology.

Wiki Memory
Memory for agents is still early, with little to no standards. “Memory” means something different to everyone. But one common pattern is emerging: wiki memory.

Depression doesn't shrink the brain like we thought it did | New Scientist
For the past decade, depression has been linked to a shrunken hippocampus, which has a vital role in memory. But a large study using up-to-date scanning techniques suggests this may not be the case

I don't understand this. 52 years later, why try and replicate the original? It's obviously not going to be the same study. The world has changed; cars, traffic, and people have changed. If one is interested in false memory, why not design the best study you can? What can you conclude meaningfully?
