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...

Impact of Groups on Groups

262
Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

Impact01:30

Impact

514
Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...

Compounds Essential to Human Function

10.5K
The human body is composed of cells that are fundamentally made up of several different molecules. These molecules are essential to carry out all physiological processes in the body and are broadly classified into organic and inorganic based on their chemical structures.
Inorganic Compounds Essential to Human Functioning
Inorganic compounds essential to human functioning include water, salts, acids, and bases. These compounds are inorganic, i.e., they do not have a carbon-hydrogen bond. Water...

Language and Cognition01:27

Language and Cognition

813
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

1.3K
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...

Area of Science:

  • Neuroscience
  • Microbiology
  • Human Health

Background:

  • The gut microbiome's role in physiological and pathological functions is a growing area of research.
  • Cognitive function is a key aspect of human health significantly influenced by various biological factors.
  • Existing research heavily relies on animal models, limiting direct applicability to human cognitive processes.

Purpose of the Study:

  • To synthesize recent human research on the gut microbiome and cognitive function.
  • To address the limitations of animal model generalizability in this field.
  • To provide an updated overview of the human gut-brain axis in relation to cognition.

Main Methods:

  • Systematic review of recent human studies.
  • Analysis of interventional and observational research.
  • Synthesis of findings linking gut microbiota composition to cognitive performance.

Main Results:

  • The gut microbiota is significantly associated with cognitive function in both healthy individuals and those with diseases.
  • Evidence suggests a potential causal relationship between gut microbial composition and cognitive abilities.
  • Some studies indicate an inverse relationship, highlighting the complexity of the gut-brain axis.

Conclusions:

  • The human gut microbiome plays a crucial role in modulating cognitive function.
  • Further human-centric research is needed to elucidate the mechanisms underlying the gut-brain connection.
  • Understanding this relationship may lead to novel therapeutic strategies for cognitive disorders.
