The female, who appears to be about 8 years old, approached a male on the playground who appears smaller than the female and approximately 6 years old and stated " Go away" while she pushed him.

Question 7: Patient Jones presented with unique symptoms after his stroke. He appeared to have increased use of his extrasensory perception (ESP). This was first noticed by his hospital caregivers and family members. Given this noticeable ability to "mind read", we decided to investigate this ability further to determine if this is indeed an increase in ESP or increase in perception and prediction abilities.

Question 8:
The residential treatment records and one-year follow-up assessments of 500 adolescents diagnosed with anorexic bulimic behavior were analyzed to determine the effects of residential treatment on adolescents diagnosed with anorexic bulimia and specifically evaluate the course of self-harm behaviors during treatment and the time spent in the residential facility with the success at their one-year follow-up. Records span the course of 5 years and 10 residential programs.

Question 9:
This study was administered online to a group of mothers of children in grades 1-5. Items were presented on a Likert scale or with drop-down selections including a measure of stress levels in their children, parent expectations of elementary school education, hours spent completing homework, extracurricular activity participation, hours spent at home, and home activity breakdown.

Question 10:
Twenty-five studies concerning television viewing and attention in children were identified using the PsychInfo database. All identified articles were included in this study in the statistical examination of the impact of television viewing on attention.

Question 11: This study compared females between the ages of 5-6, 12-13, 18-19, and 24-25 on the relationship between cognitive and physical growth as well as environmental stress levels.
Quantitative or Qualitative:
Type of Design:
Question 12: Participants were divided into one of two groups using a random assignment. Participants in the control group completed an assessment on reading comprehension including their Gender, age, and education level. The remaining participants received training on reading comprehension before completing the same assessment materials.
Quantitative or Qualitative:
Type of Design:
Question 13: I joined the fraternity to learn about the social demands during hazing practices. I realized throughout that time that the stress levels- as seen by stress behaviors such as an increase in short tempers, increase in drinking, decrease in sleep, increased anxiety, and many others- increased exponentially among not only those being hazed but also those who were hazing. There seemed to be an expectation that hazing needed to be high stakes and push the limits within the school policies.
Quantitative or Qualitative:
Type of Design:
Question 14: Fifty adult males and females participated in a study on the impact of different types of exercise on self-esteem levels. All participants completed 5 different types of moderate level exercise daily for a week. The order of the exercise regimen was counterbalanced and at the start of the program and at the end of each week of the program, participants completed a self-esteem scale.
