Psychology Quiz: Unit1: Research and the Brain

1. What is the most important reason for understanding research methods?

• so you can be a psychologist when you grow up
• so you can have something interesting to say on blind dates
• so you can evaluate information and make informed decisions
• so you can get a good grade in this class

2. Which of the following scans provide detailed information about the structure and tissues of the brain?

• PET and EEG
• case studies and causational analysis
• MRI and CAT
• Gage scans and cortical scans

3. Which of the following brain scans involves magnetic fields and radio waves that provide information about different structures in the brain?

• PET
• EEG
• CAT
• MRI

4. All of the incoming sensations from our senses (except smell) go through which brain structure first before being distributed to the rest of the brain?

• hippocampus
• reticular formation
• medulla
• thalamus

5. The difference between the highest and lowest scores in a distribution is called the:

• standard deviation.
• median.
• range.
• frequency distribution.

6. Which of the following brain structures connects the right and left hemisphere?

• cerebral cortex
• amygdala
• corpus callosum

7. The ________ the standard deviation, the more spread out scores are; the ________ the standard deviation, the more closely the scores are packed near the mean.

• higher; smaller
• more negative; more positive
• smaller; higher
• more positive; more negative

8. Why is a frequency distribution helpful?

• It allows you to know how likely a result occurred by chance alone.
• It allows you to compare one score with the scores of an imaginary group of 100 people.
• It allows you to measure the strength of a relationship between two variables.
• It allows you to determine at a glance how the scores cluster and what the most common scores are.
