Associate Prof of Psychology. I study how you remember (episodic memory), but am also interested in other areas of science (astronomy, geology, astrophysics, paleobiology, ecology, meteorology, etc) and other things too (architecture, birds, transit, etc).

How can a single cell learn without a brain? We explore this in my paper with @wallaceucsf.bsky.social! We discovered that single cells may learn using molecules similar to those that animal brains use to learn, like CaMKII. Cells can also propagate memory states to their progeny!

Can we make brains “smarter”? By boosting mitochondrial metabolism in neurons of memory circuits, we improved memory in flies and mice. Thrilled to see this work out - congrats to @amrapalianjali.bsky.social for spectacular work, and to all lab members for invaluable contributions!

Alone but not Lonely! New study finds "people with negative beliefs about being alone experience a steep increase in loneliness after spending time alone in daily life, whereas those with positive beliefs feel less lonely after spending time alone." Open Access: doi.org/10.1038/s414...
Abstract
Loneliness is a widespread issue routinely targeted by the media and public health campaigns. We propose that these efforts, though well-intentioned, may exacerbate this problem by negatively influencing a potential driver of loneliness: people’s beliefs about being alone. Supporting this thesis, we show that contemporary U.S. news articles are 10 times more likely to describe being alone as harmful than beneficial (Study 1, N = 144 articles) and that exposure to such articles causally impacts people’s beliefs about being alone (Study 2, N = 456). Further, a 2-week experience-sampling study (Study 3, N = 161) demonstrates that people with negative beliefs about being alone experience a steep increase in loneliness after spending time alone in daily life, whereas those with positive beliefs feel less lonely after spending time alone. Finally, multi-national studies demonstrate the generalizability of these results across nine countries spanning six continents (Studies 4 and 5, N = 2930). Together, these findings reveal the critical role of beliefs about being alone in shaping loneliness.

Overall, this work confirms that generation is a powerful mnemonic strategy, and offers guidance on how future work might continue to investigate this important phenomenon, which has real-world translational potential. (11/11)

Fourth, we found a number of experimental moderators that also influence the magnitude of the generation effect: see the paper to see these different moderators and how they influenced the magnitude of the generation effect. (10/11)

Eric Leshikar @leshikar.bsky.social · 15/11/2024
This finding importantly suggests that future work should carefully consider the generation task, because differences across tasks strongly influence memory. (9/11)

Eric Leshikar @leshikar.bsky.social · 15/11/2024
Specifically, we found evidence that a factor called generation constraint (limitations placed on participants by the generation task, which limits or constrains what participants can self-generate), has a large effect on the magnitude of the generation effect. (8/11)

Eric Leshikar @leshikar.bsky.social · 15/11/2024
Importantly, past theoretical and empirical work has typically assumed that all generation tasks are effectively the same in the generation effect they induce, but our meta-analysis shows that different generation tasks lead to substantial variation in memory. (7/11)

Eric Leshikar @leshikar.bsky.social · 15/11/2024
generation effect through multiple mechanisms (and we briefly propose one such framework). Third, over the history of work in the generation effect, many different types of tasks have been used to induce participants to self-generate information. (6/11)
