NSF Graduate Research Fellowship Program (GRFP)

NSF GRFP is out 2.5 months late w/key changes

1. 2nd year graduate students not eligible.

2. "alignment with Administration priorities"

3. Unlike prior years, they DO NOT specify the expected number of awards... that is a BIG problem.

The influence of the NSF Graduate Research Fellowship Program really cannot be overstated. The fact that there is still no solicitation for this year is unfair to students and risks damaging the future of American science.

I wonder if researchers who study attention and researchers who study emotion are aware about the strong parallel controversies regarding the theoretical targets?

Every few months the "good lab hands" thing comes up and it misses a key point: you can learn to have good hands. Training matters.

Good hands aren't some magic gift from the PCR gods, you have to develop them through directed repetitive practice, like any other skill

Endogenous and exogenous attentional interplay through mixed prefrontal cortex resources Di Bello et al. reveal that some neural resources in lateral PFC are shared between motor and attentional systems, enabling focus to flexibly shift in response to internal goals or external demands.

Uncertainty and reward histories have distinct effects on decisions after wins and losses Intelligent behavior necessitates an adaptive integration of feedback. It is well-known that animals asymmetrically learn from positive and negative feedback. While asymmetrical learning is a robust behavioral effect, the latent computations behind how animals represent their environments and use this to differentially weight wins and losses is poorly understood. Here we tested whether and how uncertainty and reward histories modulate the weights placed on wins and losses using a behavioral data set collected in rats. We propose a reinforcement learning model that integrates uncertainty history via an unsigned average reward prediction error and a separate subjective reward history component. We showed that in a dynamic probabilistic reversal learning task with blocks of variable reward predictability, ongoing estimation of uncertainty history and reward history both distinctly influenced rats sensitivity to wins and losses. In more predictable environments, and under low uncertainty levels, i.e., when rats were certain in making correct choices, rats weighted wins more than losses, as indicated by a higher win-stay, and lower lose-shift probability. This asymmetrical learning strategy enabled rats to remain with the correct action, while discounting the influence of rare losses. Further, male rats were more impacted by their reward history, i.e., environmental richness, when making lose-shift decisions, but conversely, female rats were more influenced by their uncertainty history. Hence, we found sex-specific contributions of these latent computations in modulating behavior. We overall demonstrate that asymmetrically weighting wins and losses could form an important behavioral strategy when adapting to ongoing changes in reward and uncertainty history.

New grants policy terms may lead to terminations after October 1st.

Don't panic, but do realize that this is a possibility.

Evolution is more like a tinkerer than an engineer. New things happen not by perfect engineering but by working with what's already available and repurposing existing objects through recombinations and modifications. This is a classic lesson for any kind of innovation, including that of new ideas..

Their NIH Grants Are Back. But Nothing Is Back to Normal. Researchers say that picking up where they left off is complicated โ€” scientifically, financially, and logistically.

The 900 grant reinstatements from @apha.org v NIH and Mass v Kennedy ruling are a huge win.

But itโ€™s not a simple or complete fix.

Not surprisingly, turning research on, then off, then on again creates major complications, chaos and inefficiency. www.chronicle.com/article/thei...

The massive list of suspended UCLA grants came out today: 300 NSF and 500 NIH grants. I am miraculously not on the list, but this is devastating. Science will be lost, progress will be frozen, people will lose jobs, and careers in science and medicine are being destroyed. This is not ok.
