Pharmacodynamics in Geriatric Patients: Effects of Age01:27

Pharmacodynamics in Geriatric Patients: Effects of Age

97
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...

Factors Affecting Perception01:25

Factors Affecting Perception

2.3K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

Stereotypes, Prejudice, and Discrimination

93.9K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Cognitive Development During Adulthood

508
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,...

Revisionist Views of Adolescent and Adult Cognition

175
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Cognitive Development During Adolescence

296
During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...

Summary
This summary is machine-generated.

Facial age perception is influenced by surrounding faces. Younger surrounding faces make a target appear younger, while older surrounding faces make it appear older, with younger flankers having a stronger effect.

Area of Science:

  • Psychology
  • Visual Perception
  • Social Cognition

Background:

  • Perception is context-dependent, influencing judgments of orientation, facial attractiveness, and expression.
  • The impact of surrounding facial context on age perception remains poorly understood.

Purpose of the Study:

  • To investigate how the age of surrounding faces (flankers) affects the perceived age of a target face.
  • To quantify the influence of younger and older flankers on age estimation.

Main Methods:

  • Participants estimated the age of a target face presented alone or surrounded by younger or older flanker faces.
  • Utilized a standardized database of passport photos with varying age differences (±5 to ±20 years).
  • Examined effects across different genders and races.

Main Results:

  • Target faces appeared younger when surrounded by younger flankers and older when surrounded by older flankers.
  • The magnitude of contextual influence was asymmetric: younger flankers had a stronger effect than older flankers.
  • This asymmetry may be linked to an own-age bias in young participants.

Conclusions:

  • Facial age perception is significantly modulated by the age of surrounding faces.
  • An own-age bias may contribute to the asymmetric influence of flanker age on perceived target age.
  • Contextual effects in facial perception are robust and extend to age estimation.
