Document Summary
Watson & morgan - in infancy original emotional reaction patterns are few; fear, rage & love. Tested infant (albert) for fear with animals, burning newspapers, etc. Infant showed no fear: later tested with loud noise: he finally cried, dropping infants caused fear when very young, less when grew older. Establishment of conditioned emotional responses: first put through all regular emotional tests - no sign of fear response. 3 d: white rat was placed with child, every time child went to touch, steel bar was struck: 11 mo. 10 d: rat was presented, child was tentative to touch. Leaned to touch but quickly pulled hand back. Joint stimulation resulted several times in infant falling over, showing signs of fear, no crying. Rat alone resulted in infant immediately crying, crawling away quickly. All other furry objects induced negative responses: 11 mo. 20 d: not as serious reaction to animals. Changed environment, needed reminder of fear once then was repeatedly seen again.
