1 Situation: A researcher is interested in whether taking vitamin C has an effect on the number of colds people get. a. If she wants to determine whether taking vitamin C actually reduces the number of colds people get, what type of research procedure should she use?b. What procedures would she follow in setting up the study? (hint: what are the components of scientific research?)c. What could she select for independent and dependent variables?d. Do you think a control group would be important? Why? What kind of condition could she use with a control group?2 Traumatic Brain Injury Linked to Criminal Behavior in Youth: Young offenders are more likely to have suffered a traumatic brain injury compared with the rest of society, according to new research. A study of 197 young male offenders found about half of them reported having had a childhood neurological injuryâ€â€three times higher than in non-offenders. Multiple head injuries were linked with carrying out more violent crimes, according to research published in the journal Neuropsychological Rehabilitation. The researchers say that while a brain injury alone is unlikely to increase a child’s chances of engaging in crime, it appeared to play a role in children who were already at risk of committing offenses. (Time, 11/11/10)1. Is the study above: CORRELATIONAL or EXPERIMENTAL?2a. If the study is correlational, is the correlation: POSITIVE or NEGATIVE? 2b. If the study is experimental, the independent variable is ___________ and the dependent variable is _________________.3. Can the authors of the study claim that traumatic brain injuries cause people to commit violent crimes? Why or why not?3 Meditation May Change Brain Structure: Meditation causes structural changes in the brain associated with memory, empathy, and stress, according to new research. Researchers, whose findings are reported in the journal Psychiatry Research: Neuroimaging, examined MRI scans of participants over a period of 8 weeks. Daily meditation sessions of 30 minutes produced measurable changes in subjects with no previous meditation history. The anxiety and stress region of the brain, the amygdala, produced less gray matter. In a non-meditating control group, these positive changes did not take place. (The New York Times, 1/28/11)1.
