Cognitive well-being (CWB) is a crucial aspect of mental health that reflects an individual’s ability to process information, adapt to new experiences, and maintain mental clarity and resilience. This article presents a control theory approach to understanding the dynamics of cognitive well-being, emphasizing the feedback loops that influence cognitive functioning. By applying principles of control theory, the study explores how individuals regulate their cognitive processes in response to environmental demands and internal goals. A systematic review of existing literature is conducted to investigate the relationship between cognitive well-being and control theory concepts, such as feedback mechanisms, stability, and adaptation. The findings suggest that cognitive well-being is influenced by the balance between internal cognitive goals and external demands, with feedback loops playing a central role in maintaining mental stability and facilitating adaptation. This article concludes by proposing strategies for enhancing cognitive well-being through interventions that optimize feedback mechanisms.
