Conditioning-Baby ALBERT
"At approximately nine months of age we ran him through the emotional tests that have become a part of our regular routine in determining whether fear reactions can be called out by other stimuli than sharp noises and removal of support. In brief, the infant was confronted suddenly and for the first time successively with a white rat, a rabbit, a dog, a monkey, with masks with and without hair, cotton wool, burning newspapers, etc. At no time did this infant ever show fear in any situation. The infant practically never cried. The test to determine whether a fear reaction could be called out by a large sound was made when he was eight months, twenty six days of age. The sound was that made by striking a hammer upon a suspended steel bar four feet in length and three-fourths of an inch in diameter."
"The child started violently, his breathing was checked and the arms were raised in a characteristic manner. On a second simulation the same thing occurred, and in addition the lips began to pucker and tremble. On the third simulation the child broke into a sudden crying fit. This is the first time an emotional situation in a laboratory has produced any fear or even crying in Albert. We had expected just these results on account of our work with other infants brought up under similar conditions. It is worthwhile to call attention to the fact that the removal of support (dropping and jerking the blanket upon which the infant was lying) was tried exhaustively upon this infant on the same occasion. It was not effective in producing the fear response."
