Some highlights: Most of this research is on college students who are currently in the context of institution-regulated learning. Spaced testing and information retrieval improves later retrieval even for items that people believe they have already learned. Massing (including cramming) helps, but more learning is achieved in the same amount of time by interleaving -- alternating between material. For example, the French mathematics curriculum with algebra and geometry learned in alternating wee...

Adopting a more active lifestyle today could have benefits for your personality decades from now – Research Digest
The main take-away is that greater physical inactivity at baseline was associated with sharper declines in conscientiousness, extraversion, agreeableness and openness, as measured two decades later, even after factoring out baseline personality and any differences in health. The pattern also wasn’t moderated by race, age, education or sex.

Memory and Brain Amyloid and Tau Effects of a Bioavailable Form of Curcumin in Non-Demented Adults: A Double-Blind, Placebo-Controlled 18-Month Trial - ScienceDirect
This is the first long-term (18 months) double-blind, placebo controlled trial of a bioavailable form of curcumin (Theracurmin® containing 90 mg of curcumin twice daily) in non-demented adults.

We found that daily oral Theracurmin led to significant memory and attention benefits.

FDDNP-PET scans performed pre- and post-treatment suggested that behavioral and cognitive benefits are associated with decreases in plaque and tangle accumulation in brain regions modulating mood and memory.

Curcumin's cognitive benefits may stem from its anti-inflammatory and/or anti-amyloid brain effects.

Is the dark really making me sad? | Ars Technica
nt shade, I become aware of just how much it shapes our perception of the world. Suddenly, things seem more three-dimensional; I feel transformed into one of those ‘merry inhabitants’ that Kittilsen imagined. When I leave the sunlight, Rjukan feels a flatter, greyer place.

As far back as the sixth century, historians were describing seasonal peaks of joy and sorrow among Scandinavians, brought about by the continuous daylight of summer and its almost complete absence in winter.

Three hundred and fifty miles south of Rjukan, and at roughly the same latitude as Edinburgh, Moscow, and Vancouver, lies Malmö in southern Sweden. In Sweden, an estimated 8 percent of the population suffers from SAD, with a further 11 percent said to suffer the winter blues.

In early January, the Sun rises at around 8:30am and sets just before 4pm. For Anna Odder Milstam, an English and Swed

Why Facts Don’t Change Our Minds - The New Yorker
Mercier and Sperber’s argument runs, more or less, as follows: Humans’ biggest advantage over other species is our ability to coöperate. Coöperation is difficult to establish and almost as difficult to sustain. For any individual, freeloading is always the best course of action. Reason developed not to enable us to solve abstract, logical problems or even to help us draw conclusions from unfamiliar data; rather, it developed to resolve the problems posed by living in collaborative groups.

How Video Games Satisfy Basic Human Needs - Facts So Romantic - Nautilus
For these researchers, incredibly, enjoyment is not the primary reason why we play video games. Enjoyment is not the primary motivation—“it is rather,” they wrote, “the result of satisfaction of basic needs.” Video game worlds provide us with places where we can act with impunity within the game’s reality. And yet, freed of meaningful consequence, law abiders continue to abide the law. The competitive continue to compete. The lonely seek community. Wherever we go, there we will be.

A record of nootropics I have tried, with thoughts about which ones worked and did not work for me. These anecdotes should be considered only as anecdotes, and one’s efforts with nootropics a hobby to put only limited amounts of time into due to the inherent limits of drugs as a force-multiplier compared to other things like programming1;
