Final answer:
Scientists prefer monkeys for certain studies on problem-solving due to the simplicity of their neural structures, ethical considerations, and their evolutionary closeness to humans. Studies such as the Harlows' rhesus monkeys research and Savage-Rumbaugh's work with bonobos offer insights into primitive problem-solving and cognition which approximates human psychology.
Step-by-step explanation:
A scientist would use a monkey over a human to study the effects of environmental noise levels on problem solving primarily because of the comparative simplicity of monkey neural structures, ethics, and the evolutionary closeness to humans. Research such as the Harlows' study on rhesus monkeys indicated that social comfort is more important than food in monkey development. Meanwhile, classic work by Wolfgang Köhler with chimpanzees showcased their capability for abstract thought and problem-solving skills. Additionally, primatologist Sue Savage-Rumbaugh's studies with bonobos revealed advanced cognitive linguistic skills, hinting at continuities that exist between humans and other primates.
While the question simplifies a decision to use monkeys, multiple factors influence the choice of non-human primates in studies including ethical considerations, brain and behavior parallels with humans, and a controlled environment for observation. Studies with non-human primates like rhesus monkeys, bonobos, and chimpanzees contribute significantly to our understanding of cognitive abilities and can provide insight into human problem-solving in the presence of environmental distractions.
