Summary
This study maps cognitive reserve research from 1998-2017, revealing key trends and influential works. It highlights the growing focus on functional ability and reserve mechanisms in dementia research.
Area of Science:
- Neuroscience and Gerontology
- Bibliometrics and Scientometrics
Background:
- Cognitive reserve (CR) research and its relation to dementia is a rapidly evolving field.
- Understanding the intellectual structure and knowledge development is crucial for advancing research.
- A scientometric review provides a quantitative analysis of the research landscape.
Purpose of the Study:
- To analyze the intellectual structure, emerging trends, and knowledge shifts in cognitive reserve and dementia research.
- To identify influential authors, journals, institutions, and countries in the field.
- To map the evolution of research topics within cognitive reserve.
Main Methods:
- Utilized Web-of-Science data from 1998-2017, encompassing 564 articles and 12,504 citations.
- Employed CiteSpace software for scientometric review and co-citation network visualization.
- Analyzed networks of authors, journals, institutions, and countries.
Main Results:
- Identified Stern Y as the most prolific and cited author.
- Revealed a central-peripheral structure in journal, institution, and country networks, with Neurology, Harvard University, and the USA leading.
- Observed significant growth in research on functional ability, executive control, mortality data, and reserve mechanisms, alongside the prominent cognitive reserve focus.
Conclusions:
- The study provides a comprehensive overview of the cognitive reserve research landscape.
- Identified critical articles and emerging trends offer new insights for future research directions.
- Facilitates better communication of key findings and exploration of data in dementia and cognitive reserve studies.

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

01:27Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

945
Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...
