Final answer:
The term 'Deep Lessoning' is likely a typo, with 'hypnosis' being the closest relevant term. Hypnosis is conducted in mental health clinics by licensed therapists or certified hypnotists and is effective for individuals open to suggestion.
Step-by-step explanation:
Deep Lessoning seems to be a typo, and assuming you meant deep learning, the term is not typically associated with a specific location or professional unless perhaps in the context of machine learning or artificial intelligence. However, in the given options, the closest matching term is hypnosis, which is usually practiced in mental health clinics by licensed therapists or certified hypnotists.
Hypnosis is a state of intense focus and minimal external attention, where a clinician uses relaxation and suggestion to try to alter a patient's thoughts and perceptions. It's particularly effective for those who are very open to suggestions, and research has shown that it can lead to global changes in brain functioning, validating its impact on cognitive processes.
