Men and women brains weight differences
Men and women brains weight differences – Researchers under the direction of Paul Farmer
of Harvard Medical School in the US have shown that the size of certain parts of the brain in women
is different from the same part of the brain in men. The frontal lobe in which the center of
decision-making and problem-solving, weighs more in women than in men. More space is also an area responsible for short-term memory and spatial orientation.

Information electronic form – Human has 295 exabits
Information electronic form – Researchers at the University of Southern California (USA) found that mankind has 295 exabits information. Personal computers and modern notebooks usually have memory approx. 100 Gb or more. In 1986. ⅓ information was recorded on paper – as archives, books, newspapers, etc.. The rest fell on the tapes, phonograph records, videos, photographs. Currently, only 0.07% of all the information on the paper. As many as 52% of global data is stored in retentive memory computers. It is followed by optical media (28% of information), DVRs (11%).

Alcohol supports memory – Moderate drinking can promote human health. A new discovery of scientists from The University of Texas at Austin. After examining the effects of alcohol on the brains of seniors.
Adults who consumed alcohol in their old age, they were healthier, distinguished by better perception and had a greater brain capacity than people who reduced their consumption of alcohol because of health problems,
– said Brian Downer, research manager.
Blood group affects memory – Causes dementia
Blood group affects memory – In a study conducted by the dr. Mary Cushman. Attended by 30 thousand. people aged from 45 years. Of this group, the researchers chose 495 participants, who in three years there were disturbances in thinking and memory problems. In the second group there were 587 people who did not detect any health problems. It has been found that the group forgetful 6% had blood group AB.
These people were as much as 82% more likely to appear at their problems with concentration, speech and short-term memory, which may signal dementia,
– summed up Mary Cushman. The most common cause of dementia is Alzheimer’s disease.

Primary Mental Abilities – Variety of independent skills
Primary Mental Abilities – Louis Thurstone (1887-1955) believed that using factor analysis can uncover a variety of independent skills. He called it the basic mental abilities (Primary Mental Abilities, PMA), and created a special test to measure them (PMA test). He appointed six basic mental abilities: understanding words, verbal fluency, the ability of numerical, reasoning ability, memory and perceptual speed.
