...psychologist Ravenna Helson, now an emeritus professor at the University of California, Berkeley, began a long-term study of 142 women, all of them 21 years old, at Mills College in Oakland, Calif. She interviewed the subjects and took measures of their personalities, drives, relationship skills and the like. Then she reinterviewed them at ages 27, 43, 52 and 61 to determine how those traits changed over time. Just last year she and a graduate student, psychologist Christopher Soto, collated the data from the 123 women who stuck with the study. The results were surprising...
While most of the findings about the effects of caffeine remain open to further testing, caffeine's boosting your brainpower has been proved beyond any reasonable doubt "As a research psychologist," says Harris Lieberman, who works in the Military Nutrition Division of the U.S. Army Research Institute of Environmental Medicine in Natick, Mass., "I use the word intelligence as an inherent trait, something permanently part of your makeup." Caffeine can't change that, Lieberman says. But what it can do, he says, is heighten your mental performance. If you're well rested, it tends to improve rudimentary brain functions, like...
...course, parents don't have to learn sign language to be active participants in their babies' development. For the past 20 years, New York University developmental psychologist Catherine Tamis-LeMonda has been observing babies as they interact with parents in "naturalistic" environments?at home, running errands, going about their everyday lives?to see how adult involvement affects language acquisition. Through longitudinal studies, she's documented that the more parents respond to babies' cries, expressions and articulations, the earlier the children will talk and the more advanced their language skills will be at age 5. Parents who respond to babies' cues?...
...grabs at waxed paper, the adult can repeat the word paper and show him or her how it makes noise or how it can be crumpled. "The infant brain craves novel stimulation, but that can be found in ordinary nonstructured, nonmarketed things around the house," says Ross Thompson, a psychologist at University of California at Davis and one of the founders of the National Scientific Council on the Developing Child, a research organization of scientists and experts on early-childhood development...
...mind than to rest the body. Indeed, most of the benefits of eight hours' sleep seem to accrue to the brain: sleep helps consolidate memory, improve judgment, promote learning and concentration, boost mood, speed reaction time and sharpen problem solving and accuracy. According to Sonia Ancoli-Israel, a psychologist at the University of California at San Diego who has done extensive studies in the aging population, lack of sleep may even mimic the symptoms of dementia. In recent preliminary findings, she was able to improve cognitive function in patients with mild to moderate Alzheimer's simply by treating their underlying...
