When John Watson said,"Give me a dozen healthy infants ...," what was he arguing that behaviour is strongly influenced by

A)  environmental factors
B)  heredity factors 
C)  cultural factors
D)  subjective factors

John Watson argued that behaviour is strongly influenced by environmental factors, as he believed that any child could be shaped to become any type of person through nurture and environment, rather than genetics or inherent traits. Watson believed that all human behaviour was the result of conditioning and that a person's environment was the primary factor in shaping their behaviour. Therefore, the best choice is A – environmental factors.
