Critique: Stimulating brain to lower pain

Today’s poster comes from kindly contributor Emma Taylor, who was generous enough to share her honours project. Click to enlarge!

Quick thoughts.

• Good structure that lets me know I read in rows.
• Visual hierarchy is generally good.
• Looks crowded. Would benefit from more space around everything, but particularly between text and edged of blue boxes they are in.
• Underlining text in discussion would probably be better as bold or italic text.
• Another editing run to cut more text might help. (I know, that bit is hard.)
