The value of physical exercise for Baby Boomers and Seniors is universally accepted. The gold standard of measuring mental abilities is the Wechsler Adult Intelligence Scale– Revised. Colloquially, it is called the “IQ Test.” Designed by psychologist David Wechsler during the Second World War, it was first applied to help discover the hidden abilities of recruits. Administering this test results in a measurement known as the intelligence quotient (IQ). An IQ score of 90 to 110 is considered normal. The IQ scores of most lawyers and doctors is estimated to fall in the range of 116 and above.
Over the years, the IQ Test has undergone extensive research cross-culturally in America. It is considered a valid and reliable measure of intelligence. It includes factors such as verbal and spatial understanding and long-term, short-term, and working memory.
But what is “intelligence”? This important question has been raised about exactly what is the meaning of intelligence and whether it can be described as a single score. Harvard Professor Richard Gardner emphatically explains his view that intelligence is a mosaic of abilities and that it can’t be reduced to a single mental ability.
