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...

Anatomy of the Heart

Anatomy of the Heart

The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

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.

Perseverative cognition, or repetitive thinking, is linked to autonomic nervous system rigidity and reduced brain connectivity. This cognitive inflexibility impacts both physical and mental health across diverse populations.

Area of Science:

Neuroscience
Psychology
Autonomic Nervous System Research

Background:

The concept of allostasis broadens stress research beyond immediate physiological responses.
Perseverative cognition, characterized by repetitive thinking, simulates ongoing stress exposure.
Cognitive inflexibility during perseverative cognition affects both bodily and brain functions.

Purpose of the Study:

To review the association between cognitive inflexibility during perseverative cognition and physiological/neurological markers.
To explore the neurobiology of brain-heart interactions in the context of perseverative cognition.
To highlight the clinical relevance of perseverative cognition as a transdiagnostic risk factor.

Main Methods:

Systematic review of studies across diverse settings, populations, and age groups.
Analysis of autonomic measures, including heart rate variability (HRV).
Integration of neuroimaging data (e.g., functional connectivity) with clinical autonomic research.

Main Results:

Consistent replication of the link between autonomic, subjective, and behavioral measures of cognitive inflexibility.
Reduced HRV during perseverative cognition correlates with impaired prefrontal inhibitory control.
Diminished prefrontal-amygdala functional connectivity observed in neuroimaging studies.

Conclusions:

Perseverative cognition is associated with autonomic nervous system rigidity and altered brain function.
Impaired prefrontal control over subcortical structures underlies these changes.
Understanding brain-heart interactions in perseverative cognition may lead to improved treatments for psychological and somatic health issues.
