Childhood maltreatment is thought to be linked to adult narcissistic traits. In particular, it is thought that the more severe the childhood maltreatment, the more a person would suffer from the vulnerable form of narcissism. Individuals with this type of personality disorder display attention seeking behaviors, lack empathy, are resentful, have an inferiority complex, and view criticism as a personal attack. As a result, these individuals can be very resentful and vindictive towards others. A research clinician has a sample of n=20 patients who have suffered extreme childhood maltreatment and agree to be assessed on a well-known interval scale for vulnerable narcissism.

- Rebecca Chory, Ph.D., now an associate professor of communication at West Virginia University, began studying the effect of such portrayals on patients' attitudes toward physicians. Using a survey of 300 undergraduate students, she compared perceptions of physicians in 1992—the end of the era when physicians were shown as all-knowing, wise father figures—with those in 1999, when shows such as ER and Chicago Hope (1994–2000) were continuing the transformation to showing the private side and lives of physicians, including vivid demonstrations of their weaknesses and insecurities. Dr. Chory found that, regardless of the respondents' personal experience with physicians, those who watched certain kinds of television had declining perceptions of physicians' composure and regard for others. Her results indicated that the more prime time physician shows that people watched in which physicians were the main characters, the more uncaring, cold, and unfriendly the respondents thought physicians…Rebecca Chory, Ph.D., now an associate professor of communication at West Virginia University, began studying the effect of such portrayals on patients' attitudes toward physicians.

Children of older parents are more likely to be in daycare and have greater independence than children of younger parents, whereas children of younger parents are more likely to be at home with parents and other siblings, and encounter more home discipline. A researcher observed the disciplinary habits of 456 families with at least one child, categorizing each as "high" or "low" in terms of disciplinary strictness. The families were also divided into older parents (those 29 years of age or younger) and older parents (30 years old and up). Are the following data consistent with the hypothesis that older parents are not as strict when disciplining their children? Calculate gamma and interpret it's direction and magnitude, and summarize your findings in a few sentences. Level of discipline Parental age 29 years or younger 30 years or…
- In studies examining the effect of humor on interpersonal attractions, McGee and Shevlin (2009) found that an individual’s sense of humor had a significant effect on how the individual was perceived by others. In one part of the study, female college students were given brief descriptions of a potential romantic partner. The fictitious male was described positively as being single and ambitious and having good job prospects. For one group of participants, the description also said that he had a great sense of humor. For another group, it said that he has no sense of humor. After reading the description, each participant was asked to rate the attractiveness of the man on a seven-point scale from 1 (very unattractive) to 7 (very attractive). A score of 4 indicates a neutral rating. The females who read the “great sense of humor” description gave the potential partner an average attractiveness score of M = 4.53 with a standard deviation of s = 1.04. If the sample consisted of n = 16…Pillman et al. (A-11) studied patients with acute brief episodes of psychoses.

- In Jolie’s new Thai restaurant, she observes the age of her customers and notes down which of the groups they belong to – ’18 years old and below’ or ‘above 18 years old’, and whether they spent more than $30 on a single meal - ‘big spender’ or ‘non-big spender’. Given that rate (big spender | above 18 years old) > rate (big spender | 18 years old and below), what conclusion can be made? a) Being a big spender and being above 18 years old are negatively associated.b) Being a big spender and being above 18 years old are positively associated.c) Being above 18 years old is positively associated with visiting her restaurant.d) Being above 18 years old causes one to become a big spender.In a 2013 study, Jonason, Jones, and Lyons studied the differences in personality traits of 263 university students and compared those traits to whether the student was a "morning type" or "evening type". They found a those who were evening type to be more, on average, more narrassistic, psychotic, and manipulative. What is the population of this study?Based on a survey of 12,344 U.S. college students and 6,729 Canadian college students, Kuo, Adlaf, Lee, Gliksman, Demers, and Wechsler (2002) report that alcohol use is more common among Canadian than U.S. students, but heavy drinking (five or more drinks in a row for males, four or more for females) is significantly higher among U.S. students than Canadian students. Is this an example of a survey research design?
