Cognitive training refers to activities and exercises designed to improve mental functions such as memory, attention, and problem-solving skills. These activities can include puzzles, memory games, and computer-based programs that challenge the brain. The goal is to enhance cognitive abilities and promote overall mental fitness. Research suggests that cognitive training can lead to improvements in specific skills, but its effects on daily life and overall intelligence are still debated. Many programs are available, often targeting different age groups, including children and the elderly, to help maintain or boost cognitive health throughout life.
