Questions and Answers

What is a key argument of Albert Bandura when criticizing evolutionary psychology?

  • Social behavior is solely influenced by biological evolution.
  • Evolutionary psychology oversimplifies human behavior by focusing only on genetic factors.
  • Environmental and biological factors mutually contribute to human adaptation. (correct)
  • Evolutionary psychology does not account for the impact of culture on behavior.

What example illustrates the concept of an evolved mechanism not being adaptive in contemporary society?

  • Humans' strong social bonds, developed for survival in prehistoric groups, are now hindering individualistic pursuits.
  • Humans' innate fear of snakes, evolved as a protective mechanism, is now causing unnecessary anxiety in modern environments.
  • Humans' tendency to overeat, rooted in a food-scarce past, contributes to health issues in modern society. (correct)
  • The human brain's capacity for language, which evolved for communication, is now being used for manipulating others.

According to Vygotsky, how do children learn to use tools?

  • By actively engaging in problem-solving tasks.
  • Through innate biological predispositions.
  • Through imitation and observation of others. (correct)
  • By trial and error, experimenting with different tools.
