The following information reports on recent studies pertaining to human intelligence. It’s intention is to serve as an updating addendum to the recently-published book, “Brighter Brains - 225 ways to elevate or injure IQ.” Links are provided to the original studies. Updates in the future will be weekly.
Dear Daughter: Go To Sleep NOW, or Get Stupid University College London research suggests that girls who have non-regular bedtimes at ages 3, 5 and 7 have significantly lower scores in reading, math, and spatial tests. The report suggests that bedtime should be no later than 9 pm, and 7:30-8:30 is ideal.
Hydrate Your Hemispheres University of East London School of Psychology research indicates that participants who drank 3 cups of water before taking tests answered the questions quicker. Researchers believe the results signify that dehydration actually shrinks the brain, causing cognitive decline.
Super Brain Map Researchers in Germany and Canada have produced a new map of the human brain - called BigBrain - that is 50X more detailed than previous brain maps. The map they constructed used a deceased 65-year-old woman’s brain that was sliced into 7,400 sections and photographed microscopically.
Artificial Intelligence Still in Toddler Phase Researchers at the University of Illinois in Chicago tested one of the best AI systems (“ConceptNet 4” - developed by M.I.T.) and determined that it had merely the IQ of a 4-year-old. The system performed extremely well on the vocabulary portion of the test, but was weak on comprehension and “common sense.”
Blood Sugar Alert! People with impaired glucose tolerance - “pre-diabetic hypoglycemia” - are at risk of cognitive decline. Areas affected include word recognition, visual verbal learning, visual spatial learning, and psychomotor. The danger can be lessened with increased exercise and fiber intake. In related news, the Diabetes drug metformin offers a 20% lower risk of dementia, claims Dr. Rachel Whitmer, from Kaiser Permanente in Oakland, California, who will present her study at an Alzheimer’s conference in Boston
Head Start is Smart Children who participated in an eight-week long Head Start program - accompanied by their parents - made gains in nonverbal IQ and language skills. The study was conducted by the University of Washington’s Brain Development Lab.
Social Isolation causes deformations in the white matter of developing children’s brains. Many believe this damage is repeated if the subjects are teenagers, adults, or prisoners in solitary confinement. The latter practice is questioned as inhumane torture.
Nature Films = Brain-Healthy A study in the journal PLoS ONE found that people who watch nature documentaries actually score better on language skill tests than those who completed online tests and other brain games.
Pass the Salt, Please Researchers say adding iodized salt to the diet can raise IQ 15 points in developing nations.
