Final answer:
The term for the manifestation and communication of feelings within a client is 'emotional expression.' This process involves both nonverbal and verbal behaviors, and is critical for the accurate conveyance of emotions in various forms of expression, including the arts.
Step-by-step explanation:
The term used to describe a rise of feelings within a client and the expression of those feelings through words or other forms of expression is known as emotional expression. Emotional expression includes both nonverbal and verbal behaviors that display an emotion. A key component of emotions involves cognitive appraisal, where an individual evaluates how a situation impacts them. This process can manifest in various forms, from physiological responses like changes in heart rate to the use of language and metaphors to describe the abstract experience of emotion. William Wordsworth once described poetry as the "spontaneous overflow of powerful feelings; it takes its origin from emotion recollected in tranquillity," highlighting the importance of emotional expression in art as well.
