G. stanley hall is, perhaps, one of the most prolific of the early american psychologists. which would not be accurately included in a list of his accomplishments?
a. founded the first laboratory of psychology in america at johns hopkins university in 1883.b. in 1887, he created the first journal of psychology in america.c. he wrote extensively on child development and education
d. he published the first american textbook of psychology, the principles of psychology, in 1840.

The option D (He published the first American textbook of psychology, The Principles of Psychology, in 1840) would NOT be accurately included in a list of his accomplishments.

Explanation: Just to elaborate a little on the answer, it can be added that G. Stanley Hall was born in 1846, so it would have been materially impossible for him to have published a book in 1840. Furthermore, The Principles of Psychology was written by William James and published in 1890. G. Stanley Hall did establish the first U.S. experimental psychology laboratory at Johns Hopkins University in 1883, created the American Journal of Psychology (the first journal of Psychology in America) in 1887, and wrote extensively on child development and education—The contents of children's minds on entering school (1893) is just an example.
