Kara explains to her roommate why Harry Harlow's experiments were so important to explaining an infant's socio-emotional development. Kara correctly says that his results demonstrate that when a child is emotionally stressed and under pressure, a comfort touch does more good and works wonder as compared to food or any other aid.
This directly explains that material aspects have less effect when a child is going through something internal. They require something that will provide them with long term comfort from within.
