Final answer:
Pan remembering the alphabet song after hearing it is an example of acoustic encoding, which is the process of remembering sounds and words.
Step-by-step explanation:
When Pan hears the alphabet song and remembers it, this is an example of acoustic encoding. Acoustic encoding is the process of remembering and understanding something you hear, such as a song or a melody. This type of encoding specifically relates to the encoding of sounds, words in particular, which is distinct from visual encoding (which involves images) and semantic encoding (which involves the meaning of words).
