Ten Practice Questions 1. People are placed in a brain scanner. While in the scanner, people are asked to focus on making a to- do list for the day while looking at a youtube video. During that time, some facial images are shown to them in their peripheral vision unannounced. Some faces shown are happy, some are fearful, and some are neutral. The brain image scans from this experimental set-up are shown below. What does the data below say about how adults and young children process emotions? a. Two options below. b. All of the options below. c. There is no brain activity when adults process happy facial expressions. d. The adult brain uses different methods for explicit processing of fearful versus happy emotions. e. 9 year olds and adults use different sides of the amygdala for implicit processing of emotions. 2. Neural stem cells can develop into which cell type(s)? a. any cell b. astrocytes, oligodendrocytes and neurons c. astrocytes and oligodendrocytes d. neurons only e. dopamine neurons only  Ten Practice Questions 3.
