2.5 - Storing Memories

Dr. Gusdaw conducted a memory experiment that examined the brain regions associated with forming implicit memories. Which of the following would be the best choice for his independent variable?

• Activation in the frontal lobes

• Activation in the hippocampus

• Activation in the cerebellum

• Activation in the occipital lobes

Which of the following is an example of a flashbulb memory?

• Barry remembers an especially bright sunrise, because he was by the ocean and the sunlight reflected off the water.

• Roberto remembers that correlation does not prove a cause-effect relationship because his teacher emphasized this fact over and over again.

• Anna remembers when her father returned from an overseas military deployment, because the day was very emotional for her.

• Kristof more clearly remembers second grade than third grade because his second-grade teacher has the same name as his neighbor.

While reading about the results of a study on memory, imagine that you read this statement: “After observing hundreds of participants across their lives, researchers found that this type of memory is nearly limitless and lasts, at times, for a lifetime.” Which variable is most likely being discussed in this description?

• Sensory memory

• Long-term memory

• Short-term memory

• Working memory

Dr. Pygmal investigates how people group similar concepts together based on their interrelations. What does Dr. Pygmal study?

• Infantile amnesia

• Semantic networks

• Semantic memory

• Episodic memory

Researchers conducted a study in which they first taught 30 new vocabulary words to a group of participants. That evening, the researchers tracked the number of hours the participants slept and the number of new vocabulary words the participants remembered the next day, finding that there was a statistically significant and positive relationship between hours slept and words remembered. Which of the following provides the most accurate interpretation of these results?

• There is a low likelihood that sleep’s effect on memory consolidation was due to chance or error.

• There is a high likelihood that sleep’s effect on semantic network formation was due to chance or error.

• There is a low likelihood that sleep’s effect on episodic memory was due to chance or error.

• There is a high likelihood that sleep’s effect on implicit memory was due to chance or error.
