Questions and Answers

What is the main criticism about using speed as a measure of intelligence in animals?

  • It's difficult to determine the motivation of each animal to carry out the task. (correct)
  • Speed can be influenced by factors other than intelligence, such as perception and motivation. (correct)
  • Animals may have different levels of motor skills, which can influence their performance. (correct)
  • Speed is not a reliable indicator of cognitive abilities in animals. (correct)

What did Bitterman's experiments with systematically varied perceptual and motivational demands demonstrate?

  • Perceptual and motivational factors can significantly affect learning outcomes in animals. (correct)
  • Animals can learn to associate specific stimuli with rewards or punishments.
  • Animals learn best when motivated by a reward.
  • The speed of learning is influenced by the complexity of the task.

What was the main finding of Garcia and Koelling's experiment with rats?

  • Rats can learn to associate different stimuli with specific outcomes.
  • Rats are more likely to associate taste with illness than visual or auditory stimuli. (correct)
  • Rats have a strong aversion to lithium chloride.
  • Rats can be trained to avoid certain stimuli through classical conditioning.
