1. Numerical information engages what cerebral networks? More specifically, what functions do the networks perform and from our previous discussions, why do you think numerical information activates these networks? What studies first provided insights into the neural roots of numerical competence?
2. What categories, according to this paper, do number assignments fall into? Define these categories and provide examples for each in relation to the example Neider used. Also, think of a new example that encompasses different aspects of numerical cognition, but do not use the one written in the article. Lastly, can you think of another category that was perhaps excluded that we use to express quantities in our every-day conversations?
3. Describe the experiment by Brannon and Terrace. What did their experiment show and what, prior to their experiment, had been a concern when testing numerical competence on animals below humans?
4. What methods do development psychologists use to ascertain if infants have the capacity for cardinality? Though there are many such experiments, describe at least one experiment psychologists used in determining if infants can engage in rudimentary arithmetic.
5. What have recent single-neuron recordings shown about rhesus monkeys' numerical representations? Does this surprise you? Why or why not? Where was the highest proportion of neural cells found for numerosity? Also, what fact about the IPS leads scientists to believe that it may be the first area to extract numerical information?
6. Explain Weber's Law and how it relates to neuronal numerical representations.
7. What is the intraparietal sulcus' main function in our brain? What are the three characteristics of numerical activation in the intraparietal sulcus? Briefly explain each.
8. What is list learning and what are "derived lists"? How do monkeys mentally categorize objects in lists? Provide an example.
9. What do fMRI studies in humans show about numerical processing? Why do you think that is?
10. How is the SNARC effect related to numerical quantity, both absolute and relative? What do the fMRI studies show about these aspects OF numerical quantity?
