Summary
This review explores four models of cognitive neuroscience of aging, including HAROLD, PASA, CRUNCH, and ELSA, to understand neurocognitive activity dynamics in older adults. These models explain brain activity patterns and support cognitive reserve for optimized performance.
Area of Science:
- Cognitive Neuroscience
- Neuroimaging
- Aging Research
Background:
- Aging impacts brain activity and cognitive functions.
- Understanding neurocognitive dynamics in older adults is crucial.
- Existing models offer insights into age-related brain changes.
Purpose of the Study:
- To review and highlight four key explanatory models of cognitive neuroscience of aging.
- To explain the dynamics of neurocognitive activity in older individuals.
- To synthesize findings compatible with neuroimaging techniques.
Main Methods:
- Literature review of four explanatory models: HAROLD, PASA, CRUNCH, and ELSA.
- Analysis of neuroimaging findings related to aging.
- Synthesis of model compatibility with empirical data.
Main Results:
- The HAROLD model emphasizes pre-frontal cortex bilaterality.
- The PASA model focuses on anterior-posterior neuronal polarization.
- The CRUNCH model links brain activity to task complexity.
- The ELSA model highlights spatio-temporal brain activity during recovery.
Conclusions:
- The four models (HAROLD, PASA, CRUNCH, ELSA) are compatible with neuroimaging findings.
- These models suggest the role of compensation strategies and cognitive reserve.
- Interventions based on these models may optimize cognitive performance in older adults.

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...

01:30Cognitive Development During Adulthood
999
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,...

Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

01:19The Effect of Aging on Tissues
4.0K
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...

01:20Introduction to Cognitive Psychology
2.8K
Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.

01:24Revisionist Views of Adolescent and Adult Cognition
351
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...
