Some researchers have suggested that intelligence is a single, general ability.
Other theories of intelligence hold that intelligence encompasses a range of aptitudes, skills, and talents.
How Do We Define Intelligence?
Verywell / JR Bee
He concluded that intelligence is a general cognitive ability that researchers can measure and express numerically.
He proposed that traditional IQ testing does not fully and accurately depict a person’s abilities.
Emotional Intelligence
Emotional intelligence(sometimes called EQ) was initially coined by psychologist Daniel Goleman.
It refers to a person’s ability to regulate emotions and use their emotions to relate to others.
Signs of emotional intelligence include strongself-awareness,empathy, embracing change, and managing emotions in difficult situations.
PsychologistAlfred Binetdeveloped the very first intelligence tests to help the French government identify schoolchildren who needed extra academic assistance.
How Psychologists and Psychiatrists Measure Intelligence
Experts use a variety of standardized tests to measure intelligence.
Others are IQ tests given to individuals.
IQ test scores average around 100.
Most children with intellectual disabilities (85%) score between 55 and 70.
Severe disabilities usually correspond to still lower scores.
No single standard for intelligence or its quantification exists as yet.
In 1920, Edward Thorndike postulated three kinds of intelligence: social, mechanical, and abstract.
Emotional intelligence (EI or EQ) is the ability to perceive, control, and evaluate emotions.
Some researchers suggest that emotional intelligence can be learned and strengthened; others claim it’s an inborn characteristic.
Generally, EI is measured by self-report and ability tests.
Intelligence develops and changes throughout life, generallypeaking in midlife.
A study published inPsychological Sciencesuggested that certain elements of fluid intelligence peak as late as 40.
