Complex video games that require problem-solving and sustained attention improve cognitive functions.

Scientific research does indeed support the claim that action or strategy video games can stimulate specific cognitive abilities, such as mental flexibility, information processing speed, and working memory. A meta-analysis published in 'Psychological Bulletin' (Bediou et al.) highlights that regular players show advantages in these tasks compared to non-players. However, it is important to note that these gains are often specific to the task practiced (near transfer) rather than inducing universal global cognitive improvement. The term 'complex' is central here: passive games do not offer the same benefits as those requiring active planning. Some discourse sometimes simplifies these results by suggesting increased intelligence, while evidence points more toward an optimization of attentional processes. In summary, it is a validated brain training tool, provided that one maintains a practice balanced with other activities such as movement and social connection.
