Statistical Reasoning In Psychology PS/390 Assignment4

1. A prison psychologist recorded the number of rule infractions for 15 prison inmates over a six-month period to be 5, 4, 2, 4, 3, 5, 2, 0, 4, 4, 5, 5, 3, 4, and 3.

 

a.                  Make a frequency table.

b.                  Make a histogram based on the frequency table.

c.                   Describe in words the shape of the histogram.

2. Identify and solve this problem by hand.

The head of public safety notices that the average driving speed at a particular intersection averages μ = 35 mph with a standard deviation of σ = 7.5 mph. After a school speed limit sign of 20 mph is placed at the intersection, the first 40 cars travel past at an average speed of 32 mph. Using the .01 significance level, was there a significant change in driving speed?

 

a.                  Sketch the distributions involved.

b.                  Figure the confidence limits for the 99% confidence interval.

 

3. A social psychologist gave a questionnaire about concern for farm workers to seven participants before and after they attended a film about union organization of farm workers. The results are shown below with high scores meaning high concern. Using the .05 significance level, do these results support the hypothesis that the film affected concern for the lives of farm workers?

4. A team of cognitive psychologists studying the effects of sleep deprivation on short-term memory decay had eight participants stay in a sleep lab for two days. Four participants were randomly assigned to a condition in which they were not permitted to sleep during that period, while the other four participants were allowed to sleep when they wanted to. At the end of the two days, the participants completed a short-term memory task that yielded the results in the table that follows. Using the .05 significance level, did sleep deprivation reduce short-term memory?

Case 7. Handling Disparate Information for Evaluating Trainees

Rashid Vaji, Ph.D., a member of the school psychology faculty at a midsize university, serves as a faculty supervisor for students assigned to externships in schools. The department has formalized a supervision and evaluation system for the extern program. Students have weekly individual meetings with the faculty supervisor and biweekly meetings with the on-site supervisor. The on-site supervisor writes a midyear (December) and end of academic year (May) evaluation of each student. The site evaluations are sent to Dr. Vaji, and he provides feedback based on the site and his own supervisory evaluation to each student. The final grade (fail, low pass, pass, high pass) is the responsibility of Dr. Vaji.

Dr. Vaji also teaches the Spring Semester graduate class on “Health Disparities in Mental Health.” One of the course requirements is for students to write weekly thought papers, in which they are required to take the perspective of therapy clients from different ethnic groups in reaction to specific session topics. Leo Watson, a second-year graduate student is one of Dr. Vaji’s externship supervisees. He is also enrolled in the Health Disparities course. Leo’s thought papers often present ethnic-minority adolescents as prone to violence and unable to “grasp” the insights offered by school psychologists. In a classroom role-playing exercise, Leo “plays” an ethnic-minority student client as slumping in the chair not understanding the psychologist and giving angry retorts. In written comments on these thought papers and class feedback, Dr. Vaji encourages Leo to incorporate more of the readings on racial/ethnic discrimination and multicultural competence into his papers and to

provide more complex perspectives on clients.

 

One day during his office hours, three students from the class come to Dr. Vaji’s office to complain about Leo’s behavior outside the classroom. They describe incidents in which Leo uses derogatory ethnic labels to describe his externship clients and brags about “putting one over” on his site supervisors by describing these clients in “glowing” terms just to satisfy his supervisors’ “stupid liberal do-good” attitudes. They also report an incident at a local bar at which Leo was seen harassing an African American waitress using racial slurs.

 

After the students have left his office, Dr. Vaji reviews his midyear evaluation and supervision notes on Leo and the midyear on-site supervisor’s report. In his own evaluation report Dr. Vaji had written, “Leo often articulates a strong sense of duty to help his ethnic minority students overcome past discrimination but needs additional growth and supervision in applying a multicultural perspective into his clinical work.” The on-site supervisor’s evaluation states that Leo has a wonderful attitude towards his student clients . . . Unfortunately evaluation of his treatment skills is limited because Leo has had less cases to discuss than some of his peers since a larger than usual number of students have stopped coming to their sessions with him.

It is the middle of the Spring Semester, and Dr. Vaji still has approximately 6 weeks of supervision left with Leo. The students’ complaints about Leo, while more extreme, are consistent with what Dr. Vaji has observed in Leo’s class papers and role-playing exercises. However, these complaints are very different from his presentation during on-site supervision. If Leo has been intentionally deceiving both supervisors, then he may be more ineffective or harmful as a therapist to his current clients than either supervisor realized. In addition, purposeful attempts to deceive the supervisors might indicate a personality disorder or lack of integrity that if left unaddressed might be harmful to adolescent clients in the future.

Ethical Dilemma

Dr. Vaji would like to meet with Leo at minimum to discuss ways to retain adolescent clients and to improve his multicultural treatment skills. He does not know to what extent his conversation with Leo and final supervisory report should be influenced by the information provided by the graduate students.

Compare And Contrast Theoretical Perspectives

There are many different theoretical perspectives of human behavior. These perspectives influence the way you relate to others, conceptualize the development of maladaptive and adaptive behaviors, and interpret your worldview.

Tasks:

Using your textbook, the Argosy University online library resources, and the Internet, explore these concepts and complete the following tasks:

  • Analyze and compare and contrast two theoretical orientations that attempt to explain human behavior.
  • Develop a detailed case vignette that addresses multidimensional aspects of human behavior (i.e., maladaptive and adaptive beliefs, recent role transitions, support networks, and familial and cultural contexts). You can use the cases included in the reading material or course room as guides.
  • Apply one of the two theoretical orientations you chose for your case to explain the individual’s behavior.
  • Be sure to consider all dimensions of human behavior (psychological, social, biological, and spiritual) and synthesize in your paper how they fit within your theoretical framework.

Submission Details:

  • By Saturday, September 26, 2015, post your responses to this Discussion Area in a minimum of 300 words. Your response should rely upon at least two sources from professional literature.
