    "concept_summary": "Harry Kahne claims that through extensive mental training he can execute six separate mental operations at once, involving at least 14 distinct cognitive processes. He attributes this to focused attention, mental exercise, and a systematic method of 'forgettery' to clear unwanted thoughts.",
