In 1958, Harry Harlow famously demonstrated, in a still controversial and haunting study, that tactile stimulation can be more desirable than food. Harlow raised infant rhesus monkeys without mothers and gave them a choice between two artificial surrogate mothers. Both were constructed of wood and wire mesh.The difference was that one had a bottle of milk while the other one was covered with cloth. To most psychologists’ surprise, the monkeys bonded with the cloth mother that lacked a source of nutrition. Since then numerous studies from baby rodents to neonates have shown the importance of tactile stimulation. Yet, 50 years on, few architects have studied how a design’s tactile experience might affect its users. In all likelihood, the effects of a design’s tactile properties are probably minuscule when compared to the studies mentioned above; they are categorically different in terms of tactile engagement. Still, the effects could be meaningful and measurable when it comes to a person’s social behavior, self-perception, enjoyment of, and comfort in a building.
