A recent research study investigated how sleep and memory were related. It did this by following 500 students, and measuring how much people studied the week before an exam, how much they slept that week, and how well they did on the exam.

question
Dr. Phil was interested in the effect of listening to Mozart on violin playing skill. The researcher recruited 50 violin players, and tested their violin skills. He then had them listen to 1 hour of Mozart per week over a six month period. After the six month period was over, the violinists then came back for a second test of their skills. He found that all 50 violinists had gotten significantly better at playing the violin. Based on that study alone, can we conclude that listening Mozart helps with violin performance skill? Why or why not? No, because Dr. Phil's sample size was too small to be sure about the results. Yes, because the violin performance for all 50 people got better, we are sure the effect of listening to Mozart is real and strong. No, because there was no control group in the study, so we cannot rule out the placebo effect Yes, because Dr. Phil did an experiment, it is fair to conclude a cause and effect relationship between listening to Mozart and violin playing performance.
answer
No, because there was no control group in the study, so we cannot rule out the placebo effect
question
Dr. Maria is interested in the relationship between marijuana and memory. She recruited 100 participants, and randomly assigned 50 to an experimental group, and 50 to a control group. The participants in the experimental group ate some pot brownies. The participants in the control group ate some regular brownies. Then, all 100 participants watched an episode of a TV show they had never seen before. Afterwards, they had to make a list of the names of all the different characters that appeared in the show. Dr. Maria found that people in the control group was able to remember twice as many names as people in the group that ate pot brownies. What can we conclude from this study? That marijuana permanently damages your memory We cannot conclude anything, because the experiment did not have an independent variable. We cannot conclude anything, because the experiment did not control for the fact that some participants may have different responses to taking marijuana That taking marijuana impaired people's memory performance while they were high
answer
That taking marijuana impaired people's memory performance while they were high
question
In Dr. Maria's study, the number of names a person could remember was the: Dependent variable Independent variable Confounding Variable Controlled Variable

Yes, it is possible that the people who ate pot brownies did worse because they expected to do worse

question
In class, we discussed an experiment that looked at the effect of learning and exercise on the structure of rat brains. What was the conclusion of that study? An enriched learning environment was necessary both for making more neural connections and for increasing blood flow to the brain and increasing its nutritional health. Exercise was necessary both for making more neural connections and for increasing blood flow to the brain and increasing its nutritional health. An enriched learning environment led to the creation of more neural connections, and exercise was necessary for increasing blood flow to the brain and increasing its nutritional health. The brain's structure is determined purely by your genes, and neither learning nor exercise had an effect on the brain's structure
answer
An enriched learning environment led to the creation of more neural connections, and exercise was necessary for increasing blood flow to the brain and increasing its nutritional health.

Why is it inaccurate to say that daydreaming is a "total waste of time"? ​Because daydreaming gives the brain an opportunity to replenish its supply of spent neurotransmitters, particularly dopamine and serotonin. ​Because synaptic pruning, which is essential to the overall health of the brain, occur at higher rates during moments of daydreaming. ​Because we often think about past experiences and plan our future when the DMN is active during daydreaming. ​Because daydreaming gives our brain an opportunity to capture more of the essential REM waves needed for repair and growth.
answer
​Because we often think about past experiences and plan our future when the DMN is active during daydreaming.
