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...

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...

Introduction to Cognitive Psychology

Introduction to Cognitive Psychology

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...

Background:

Cognitive decline is a prevalent issue in hemodialysis patients, significantly increasing mortality risk.
Intradialytic interventions, such as cognitive training (CT) and exercise training (ET), show potential in preserving cognitive function during dialysis.

Purpose of the Study:

To investigate the impact of intradialytic cognitive training (CT) and exercise training (ET) on cognitive function in hemodialysis patients.
To compare the effects of CT and ET against standard care (SC) on global cognitive function, psychomotor speed, and executive function.

Main Methods:

A pilot randomized controlled trial involving 20 hemodialysis patients was conducted over 3 months.
Participants were assigned to intradialytic CT (tablet-based brain games), ET (foot peddlers), or SC.
Cognitive function was assessed using the Modified Mini Mental Status Exam (3MS), Trail Making Tests A and B (TMTA, TMTB), and TMTB-TMTA for executive function.

Main Results:

Patients receiving SC showed a decline in psychomotor speed and executive function over 3 months (p < 0.055).
CT and ET groups did not exhibit this decline (p > 0.05).
Compared to SC, CT and ET showed statistically significant improvements in psychomotor speed (TMTB: p=0.04 for CT, p=0.03 for ET) and trends towards improvement in other cognitive measures.

Conclusions:

Preliminary findings suggest that intradialytic CT and ET may prevent cognitive decline in psychomotor speed and executive function among hemodialysis patients.
Further replication in larger studies is warranted to confirm these promising results.
