Abstract

The objective of this paper is to examine whether the category of affordances and the potential mechanisms governing their actualization can offer a valuable framework for a deeper understanding of mental disorders, particularly addiction. In recent years, the category of affordances has been applied in analyzing schizophrenia, depression, or obsessive-compulsive disorder (OCD). In the paper we concentrate on substance use disorder (SUD) and argue that it can be characterized in terms of reshaping the field of affordances and an inability to inhibit inappropriate affordances. To support this approach, we refer to the neuronal mechanism (involving the cortico-subcortical loops (CSL)) that is responsible for decision-making and action choice as part of a continuous competition between possible patterns of interaction with the environment. In the context of addiction, this mechanism is impaired, resulting in disruptions to motor, emotional, and cognitive functions, including decision-making. The adopted perspective allows the study of addiction to include descriptions at the sub-personal, personal, and supra-personal levels, which addresses both phenomenological descriptions of people with SUD and the neural mechanisms behind them. Moreover, this perspective has potential applications in various therapeutic strategies.
