Question

ludwig, a cellist, is memorizing a musical composition just by listening to it, without refering to the sheet music. he most likely is using a(n)

visual code

acoustic code

subliminal stimulation

memory trace

Explanation:

• Visual code: Relates to visual stimuli like images or written text. Since Ludwig is memorizing by listening (auditory input), this is not relevant.
• Acoustic code: Deals with encoding information based on sound. As Ludwig is using the auditory (listening) modality to memorize the musical composition, this fits.
• Subliminal stimulation: Involves stimuli below the threshold of conscious awareness. There's no indication of such a process here.
• Memory trace: A more general term for the physical representation of memory in the brain. It's too broad compared to the specific auditory - based encoding (acoustic code) relevant to the scenario.

Answer:

acoustic code
