Final answer:
The claim that Louis Terman proved intelligence is solely based on genetics is false. Terman and other researchers found that intelligence results from a mix of genetic and environmental factors, and contemporary psychological research supports this multifactorial view of intelligence.
Step-by-step explanation:
The statement that Louis Terman proved that intelligence test scores are entirely based on genetics is false. Terman, best-known for his work in intelligence testing and for expanding upon Alfred Binet's original work, contributed extensively to the understanding of IQ and intelligence. However, Terman himself did not claim that intelligence was solely based on genetics; rather, his studies suggested that there are multiple factors including genetics that contribute to intelligence. It's important to know that the IQ test most widely used today was developed by David Wechsler, not Terman or Binet.
In understanding intelligence, it's crucial to consider both genetic and environmental factors. Research has indicated that although there is a genetic component to intelligence, environmental influences also play a significant role in the development of cognitive abilities. Moreover, arguments that tie intelligence to race or socioeconomic status have been widely contested and criticized for their methodological flaws and bias. The consensus in the contemporary field of psychological research is that intelligence is a complex trait influenced by a combination of genetic predispositions and environmental conditions.
