Dimensions of Health and Illness01:21

Dimensions of Health and Illness

9.2K
The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.

Intelligence01:27

Intelligence

8.1K
The term "intelligence" is complex because it refers to both behavior and individuals, and its interpretation varies across cultures. European Americans tend to link intelligence with reasoning and cognitive skills, while in Kenya, it is tied to responsible participation in family and social life. In Uganda, intelligence is seen as the ability to know the right actions and carry them out effectively, while the Iatmul people of Papua New Guinea associate it with the capacity to remember...

Triarchic Theory of Intelligence01:24

Triarchic Theory of Intelligence

9.2K
Robert Sternberg's triarchic theory of intelligence posits that intelligence is composed of three distinct but interrelated components: analytical, creative, and practical intelligence.

Measures of Intelligence01:29

Measures of Intelligence

8.0K
Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...

Biological Influences on Intelligence01:30

Biological Influences on Intelligence

322
Intelligence is often thought to be linked to brain size, but the relationship is more complex than that. While brain size does correlate modestly with some abilities, like verbal skills, the connection is weaker for others, such as spatial reasoning. Other factors, like brain structure, also play crucial roles. For instance, despite Einstein's smaller-than-average brain, his parietal cortex, which is involved in spatial reasoning, was 15% wider, suggesting that neural density might matter...

Wechsler's Contribution to Measures of Intelligence01:23

Wechsler's Contribution to Measures of Intelligence

1.8K
David Wechsler, a psychologist who worked with World War I veterans, developed a significant IQ test in 1939 called the Wechsler-Bellevue Intelligence Scale. This test was innovative because it combined several subtests that measured both verbal and nonverbal skills, reflecting Wechsler's belief that intelligence is a global capacity involving purposeful action, rational thinking, and effective interaction with the environment. This test later evolved into the Wechsler Adult Intelligence...

Area of Science:

  • Cognitive Epidemiology
  • Psychology
  • Public Health

Background:

  • Cognitive epidemiology investigates links between cognitive abilities and health.
  • Understanding intelligence-health associations has advanced with population-scale data over the last decade.

Purpose of the Study:

  • To review a decade of research on intelligence and health outcomes.
  • To explore intelligence's association with mortality, diseases, and biomarkers.
  • To examine confounding factors and genetic influences on the intelligence-health link.

Main Methods:

  • Review of population-scale data and existing literature.
  • Analysis of intelligence associations with all-cause mortality and specific health indicators.
  • Exploration of socioeconomic status, education, and behavioral factors.

Main Results:

  • Intelligence is prospectively associated with all-cause mortality and various health outcomes.
  • Associations are examined across the adult life course, considering specific diseases and biomarkers.
  • The role of education, socioeconomic status, and behaviors in mediating these associations is investigated.

Conclusions:

  • Intelligence is a significant predictor of health and longevity.
  • Further research incorporating genetic data and cross-disciplinary approaches is needed.
  • Advances in cognitive epidemiology require a shared knowledge base among contributing fields.
