John Broadus Watson (January 9, 1878 – September 25, 1958) was an American psychologist who popularized the scientific theory of behaviorism, establishing it as a psychological school.[3] Watson advanced this change in the psychological discipline through his 1913 address at Columbia University, titled Psychology as the Behaviorist Views It.[4] Through his behaviorist approach, Watson conducted research on animal behavior, child rearing, and advertising, as well as conducting the controversial \"Little Albert\" experiment and the Kerplunk experiment. He was also the editor of Psychological Review from 1910 to 1915.[5] A Review of General Psychology survey, published in 2002, ranked Watson as the 17th most cited psychologist of the 20th century.The 20th century marked the formation of qualitative distinctions between children and adults.[36] In 1928, Watson wrote the book Psychological Care of Infant and Child with help from Rosalie Rayner, his assistant and wife. In it, Watson explains that behaviorists were starting to believe psychological care and analysis were required for infants and children.[37] All of Watson\'s exclamations were due to his belief that children should be treated as a young adult. As such, he warns against the inevitable dangers of a mother providing too much love and affection, because love—along with everything else understood by the behaviorist perspective—Watson argues, is conditioned. He uses invalidism to support his warning, contending that, since society does not overly comfort children as they become young adults in the real world, parents should not set up these unrealistic expectations. Moreover, he disapproves of thumb sucking, masturbation, homosexuality, and encourages parents to be honest with their children about sex.[38] He would reason such views by saying that \"all of the weaknesses, reserves, fears, cautions, and inferiorities of our parents are stamped into us with sledge hammer blows,\"[9] inferring that emotional disabilities were the result of personal treatment, not inheritance.[9]Watson deemed his slogan to be \"not more babies but better brought up babies,\" in support of the \'nurture\' side of the \'nature vs nurture\' debate, claiming that the world would benefit from extinguishing pregnancies for 20 years while enough data was gathered to ensure an efficient child-rearing process. Further emphasizing nurture, Watson argued that nothing is instinctual, but rather everything is built into a child through the interaction with their environment. Parents, therefore, hold complete responsibility as they choose what environment to allow their child to develop in.[37]Though having researched many topics throughout career, child-rearing became Watson\'s most prized interest. His book would be extremely popular, having sold 100,000 copies after just a few months of release. Many critics were surprised to see even his contemporaries come to accept his views.[39] His emphasis on child development started to become a new phenomenon and would influence some of his successors, though the field had already been delved into by psychologists prior to Warson. G. Stanley Hall, for instance, became very well known for his 1904 book Adolescence. Hall\'s beliefs differed from Watson\'s behaviorism, as the former believed that one\'s behavior is mostly shaped by heredity and genetically predetermined factors, especially during childhood. His most famous concept, the storm and stress theory, normalized adolescents’ tendency to act out with conflicting mood swings.[40]Although he wrote extensively on child-rearing, including in Psychological Care of Infant and Child, as well as in many popular magazines, Watson later regretted having written in the area altogether, conceding that he \"did not know enough\" to do a good job.This is a First Edition, from 1928.
