Cognitive Dissonance01:38

Cognitive Dissonance

37.5K
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...

Language and Cognition

763
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 Therapy01:25

Cognitive Therapy

1.0K
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

369
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 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...

Introduction to Cognitive Psychology

2.3K
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.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

Area of Science:

  • Neuroscience
  • Cerebrovascular Medicine
  • Cognitive Science

Background:

  • The brain relies on intricate communication with cerebral vasculature to meet metabolic needs.
  • Cerebrovascular function and integrity are vital for brain health; disruptions can cause acute and chronic issues.
  • Cognitive impairment, including Alzheimer's disease, is associated with cerebrovascular changes and reduced cerebral blood flow.

Purpose of the Study:

  • To review the contribution of two major vasoactive pathways to cerebrovascular dysfunction.
  • To explore the link between these pathways, cerebrovascular dysfunction, and cognitive impairment.
  • To identify potential early intervention strategies for cerebrovascular dysfunction and cognitive decline.

Main Methods:

  • Focused review of scientific literature.
  • Analysis of the role of specific vasoactive pathways.
  • Examination of evidence linking cerebrovascular function to cognitive status.

Main Results:

  • Cerebrovascular dysfunction is a common feature across the spectrum of cognitive impairment.
  • Specific vasoactive pathways significantly influence cerebrovascular integrity and brain function.
  • Alterations in these pathways can precede or exacerbate cognitive deficits.

Conclusions:

  • Understanding the role of vasoactive pathways is key to addressing cerebrovascular dysfunction.
  • Targeting these pathways may offer novel strategies for preventing or treating cognitive impairment.
  • Early intervention focused on cerebrovascular health holds promise for maintaining cognitive function.
