Which of the following terms describes an individual's inability to clearly express their emotions?

The term that accurately describes an individual's inability to clearly express their emotions is emotional dysregulation. This concept refers to difficulties in managing emotional responses, which can lead to challenges in expressing feelings appropriately or in a manner that others can understand. Individuals struggling with emotional dysregulation may experience intense emotions that they cannot effectively communicate, leading to misunderstandings in interpersonal interactions.

The other terms can be distinguished from emotional dysregulation by their specific definitions. Affect regulation pertains to the ability to control and manage one’s emotional responses, meaning that a problem with affect regulation could indicate an inability to manage emotions rather than express them. Expressive aphasia is a language disorder that affects a person's ability to speak and write, specifically impairing verbal expression, but it is unrelated to the emotional aspect. Cognitive dissonance refers to the mental discomfort experienced when holding two conflicting beliefs, values, or attitudes, which does not involve the capacity to express emotions. Thus, emotional dysregulation is the most fitting term for the inability to convey emotions clearly.
