Summary
Home-based cognitive training (CT) improved cognitive performance in older adults. A 10-week program enhanced processing speed and working memory, suggesting benefits for cognitive health maintenance.
Area of Science:
- Neuroscience
- Gerontology
- Cognitive Psychology
Background:
- Cognitive decline is a concern for aging populations.
- Maintaining cognitive function is crucial for healthy aging.
Purpose of the Study:
- To evaluate the effectiveness of a home-based adaptive cognitive training (CT) program.
- To assess cognitive performance changes in cognitively normal older adults.
Main Methods:
- Sixty-eight older adults were randomized into CT or active control (AC) groups.
- Training involved 35 hours over 10 weeks (42 min/day, 5 days/week).
- Neuropsychological tests measured processing speed, working memory, and executive control pre- and post-intervention.
Main Results:
- No baseline performance differences between groups.
- CT participants showed significant improvements in the overall cognitive composite score.
- Improvements were driven by enhanced processing speed and working memory.
Conclusions:
- A brief, home-based cognitive training program can yield measurable cognitive benefits.
- These findings suggest CT may support cognitive health maintenance in older adults.

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...

01:24Revisionist Views of Adolescent and Adult Cognition

A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

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, 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...

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 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.
