Retention is a research area that focuses on understanding and improving the ability of individuals to remember information or skills over time. This area of study encompasses a variety of factors that influence retention, such as the strength of the initial learning experience, the frequency of practice, the relevance of the information, and the impact of external factors like stress or distractions. Researchers in this field often use a combination of cognitive psychology, neuroscience, and educational techniques to explore how memory works and develop strategies to enhance retention and learning outcomes.
