Cognitive Dissonance

Cognitive Dissonance

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...

Performing a Simple Data Analysis using MS-Excel Function

Microsoft Excel offers a suite of functions and tools ideal for statistical analysis, making it accessible to students and researchers. This article outlines fundamental Excel functions pivotal for data analysis.
SUM: This function calculates the total sum of a range of values. It's the foundation for aggregating data, essential for determining overall trends and totals in datasets.
AVERAGE: It computes the mean value of a given set of numbers, providing a quick insight into the central...

Language and Cognition

Language 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.

Cognitive Therapy

Cognitive Therapy

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...

Cognition and Behavior

Cognition and Behavior

Social psychology examines the complex interplay between individual mental processes and social interactions. Historically, the field was divided into two domains: social behavior and social cognition. Researchers focusing on social behavior analyzed actions within social contexts, such as conformity, aggression, or cooperation. Meanwhile, social cognition researchers investigated how people perceive, interpret, and mentally represent their social environments. However, modern perspectives no...

Cognitive Learning

Cognitive Learning

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Summary

This summary is machine-generated.

Microvascular endothelial function is not directly linked to cognitive decline. After adjusting for age, sex, and education, the initial associations between endothelial function and cognitive performance disappeared, suggesting these factors explain the relationship.

Background:

Impaired microvascular endothelial function is hypothesized to contribute to cognitive decline.
Existing research on this association presents inconsistent findings.
The ELSA-Brasil cohort study provides a valuable dataset for investigating this relationship.

Purpose of the Study:

To examine the association between microvascular endothelial function and cognitive performance.
To investigate the relationship in a large Brazilian cohort (ELSA-Brasil).
To determine if this association persists after accounting for key demographic factors.

Main Methods:

Peripheral arterial tonometry (PAT) was used to assess microvascular endothelial function (PAT-ratio and mean baseline pulse amplitude - BPA).
Cognitive tests covered memory, verbal fluency, and executive function.
Linear regression and generalized linear models were employed for cross-sectional and longitudinal analyses.

Main Results:

Unadjusted analyses showed associations between BPA, PAT-ratio, and worse cognitive performance across global, memory, and verbal fluency domains.
After adjusting for age, sex, and education, these associations became statistically non-significant.
Longitudinal analyses revealed no significant association between microvascular endothelial function and cognitive function over time.

Conclusions:

The observed associations between microvascular endothelial function and cognitive performance are likely explained by demographic factors such as age, sex, and education.
Measures of microvascular endothelial function may have limited utility in predicting preclinical cognitive deficits.
Further research is needed to clarify the complex interplay between vascular health and cognition.
