Answer:
D. Intelligence Quotient
Read Explanation:
William Stern (1871–1938) is known for his work in several areas of psychology, including:
Intelligence quotient (IQ): Stern invented the IQ formula in 1912, which is calculated by dividing mental age by chronological age and multiplying by 100.
Differential psychology: Stern is credited with establishing the field of differential psychology, which combines population-based studies with individual-focused approaches.
Personalistic psychology: Stern originated this school of psychology, which focuses on the individual by examining personality traits and how they interact to create the self.
Child psychology: Stern was a pioneer in this field, and wrote several books based on diaries he kept with his wife about the psychological development of their children.
Forensic psychology: Stern was a pioneer in this field.
Tone variator: Stern invented this device to study how humans perceive sound.
Stern's work was groundbreaking and influential, and he is considered one of the founders of the psychology of individual differences. However, some say that Stern has been misrepresented, and that his contributions are often disproportionately associated with intelligence testing.
