Unrealistic Optimism Bias01:30

Unrealistic Optimism Bias

89
Unrealistic optimism bias is the tendency to overestimate the likelihood of positive outcomes. This cognitive bias makes individuals believe they are less likely to experience failures, setbacks, or risks and more likely to succeed than others. For example, people may assume they are less prone to health issues, accidents, or financial struggles than their peers, even when they share similar risk factors.One key component of this bias is the above-average effect, where individuals perceive...

Aging

423
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Longitudinal Research

12.8K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

3.0K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

500
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Pharmacodynamics in Geriatric Patients: Effects of Age01:27

Pharmacodynamics in Geriatric Patients: Effects of Age

93
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Area of Science:

  • Gerontology
  • Psychology
  • Public Health

Background:

  • Optimism is known to benefit health and survival in adults over 65.
  • Limited research exists on whether optimism continues to impact survival in individuals beyond 85 years of age.

Purpose of the Study:

  • To investigate the hypothesis that optimism at ages 85 and 90 is associated with improved survival.
  • To determine if optimism confers survival benefits in advanced old age.

Main Methods:

  • Utilized data from the Jerusalem Longitudinal Study (1990-2020) with participants born in 1920-1921.
  • Assessed optimism using the Scale of Subjective Wellbeing for Older Persons (Op-Total, Op-Future, Op-Happy) at ages 85 and 90.
  • Analyzed 5-year mortality, adjusting for numerous health and demographic factors.

Main Results:

  • Mortality rates were 33.2% between ages 85-90 and 44.3% between 90-95.
  • All optimism measures (Op-Total, Op-Future, Op-Happy) at ages 85 and 90 significantly predicted improved 5-year survival.
  • These associations remained robust after adjusting for various confounders and excluding specific subgroups.

Conclusions:

  • Optimism continues to provide a survival advantage in advanced old age.
  • The findings support the hypothesis that optimism is a significant factor for longevity, irrespective of age.
