Final answer:
Experts agree with Salthouse but also consider cultural factors, human interactions, and environmental context as significant determinants alongside biophysical systems in affecting variables such as productivity and phenotypes. In education, structural issues may also be key in influencing student performance, not just financial resources.
Step-by-step explanation:
Experts concur with Salthouse's theory, yet they postulate that cultural factors and human interaction elements, such as different supervisory styles, play a significant role in outcomes, alongside biophysical systems. The literature suggests that although genetic and biophysical factors are crucial, the environmental context can heavily influence phenotypes, as seen with the effect of sun exposure on skin color or temperature-dependent sеx determination in reptiles. Additionally, in the realm of education, the impact of resource allocation is questioned by experts who propose that structural issues within educational systems may also significantly affect student performance gains.
