The sketchpad splits into a visual cache and inner scribe

Correct: C — A visual cache (form/colour) and an inner scribe (movement/sequence)

Logie's two-component model proposes that the visual cache passively holds static visual information (what something looks like) while the inner scribe actively rehearses spatial sequences and supports planning of movement. Behavioural evidence shows that dynamic spatial-sequence interference selectively disrupts inner-scribe tasks, while static visual interference disrupts cache-loaded tasks. Neuropsychological dissociations and fMRI studies have replicated the visual/spatial split, mapping cache-like activity to ventral and scribe-like activity to dorsal streams.
