John Broadus Watson was a famous American psychologist who lived between 1878 and 1958. He was born in Greenville, South Carolina, to Pickens and Emma Watson and was the fourth of six children. The family was not well off financially and John did not have an easy childhood. Despite the poverty that overwhelmed the family, John's father became an alcoholic and cared less about his family. However, Emma, ​​John's mother, was a devout religious woman who struggled to care for her children with less support from her husband. In 1891, John's father left the family and disappeared after having extramarital affairs with other women. The infidelity put a strain on his marriage to Emma and his relationship with his children. After his father's passing, John became unruly and confused due to the lack of comprehensive parental care from both parents. He became rebellious at school and did not want to listen to his teachers' advice. He bullied classmates and was involved in other antisocial behaviors that were completely unacceptable in the school environment, and he became violent and even rebelled against his mother (Buckley, 1989). Watson's negative attitude towards education did not last forever and changed after he was accepted to Furman University where he began his education at the age of sixteen in 1894. John's life began to change direction with his enrollment and the help of his professor Gordon Moore. He subsequently developed a positive attitude towards academic work as he realized that at least he could now contribute to the community regardless of his family's social class. His academic performance was quite brilliant and he graduated from Furman University with a master's degree in 1899. He subsequently enrolled in......half of the work......training is introduced even though the previous pattern of behavior is already established by reinforcement (Cherry, 2011). In conclusion, behaviorism theory relies on observable behaviors to facilitate quantification and data collection. Effective techniques such as behavioral intervention and discrete trial training come from this school of thought. The approaches are very essential to alter maladaptive behaviors in adults and children (Cherry, 2011). Today, conditioning and the use of rewards and punishments are used to help people learn accepted behaviors and in other cases to help them stop problematic behaviors (Coon & Mitterer, 2008). This made behavior modification and training easy and possible. Thus, Dr. John Watson played an extraordinary role in the transition of psychology from the work of earlier scholars to that of modern scholars.
