Harry F. Harlow
Affection and comfort are needs, not luxuries.
American psychologist known for rhesus monkey studies on attachment, contact comfort and social deprivation.
Affection and bodily comfort are basic psychological needs, not luxuries.
Who they were
Harry Harlow overturned the idea that infants bond simply with whoever feeds them. In his studies, young monkeys clung to a soft surrogate over a wire one that held the food — showing that comfort, warmth and closeness are basic needs in their own right, and that their absence leaves deep marks.
