What is the phonological loop?
Deals with auditory information
Limited capacity
Baddely divided into two parts: articulatory processes (inner voice) and phonological store (inner ear)
Articulatory processes keep information in the phonological store through repetition
Phonological store stores recently heard words
What is some research for the phonological loop?
Trojani and Grossi (1995) - reported a case study of someone with brain damage affecting the function of his PL but not his VSS. Shows they are separate systems
