CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Rhesus infants raised with a milk-supplying metal surrogate had softer feces than infants raised with a milk-supplying fluffy surrogate. Harlow posited that the infants with the metal surrogates suffered from psychological disturbances, which manifested in digestive problems.

Detailed explanation-2: -To investigate the debate, Harlow created inanimate surrogate mothers for the rhesus infants from wire and wood. Each infant became attached to its particular mother, recognizing its unique face and preferring it above all others.

Detailed explanation-3: -Harlow’s first observation was that monkeys who had a choice of mothers spent far more time clinging to the terry cloth surrogates, even when their physical nourishment came from bottles mounted on the bare wire mothers. This suggested that infant love was no simple response to the satisfaction of physiological needs.

Detailed explanation-4: -Harlow asserted that the need for tactile or contact comfort explains how attachment develops. Harlow demonstrated this fact by giving monkeys two surrogate mothers: a wire mother, who provided nourishment; and a cloth mother, who provided contact comfort. The monkeys always preferred the cloth mother.
