Has the primary researcher committed an ethical violation?

PART1-Due Thursday Respond to the following in a minimum of 175 words:

Consider the following scenario: 60 children, ages 3-5, are selected to participate in a program for developing non-verbal communication skills. The children were selected on the basis of extremely low scores on a test of non-verbal communication. After participating in the program, the children are re-tested. An average improvement of 59% is observed in the quality of non-verbal communications. What threat to internal validity is present in this situation? How can this confound be eliminated?

PART3- Analysis of Ethical Dilemma

Read the following scenario:

• A well-known researcher at a major university has two graduate student assistants. He conducts three studies in his laboratory, all of which involve very labor-intensive procedures. The graduate research assistants complete all of the data collection. They also assist in writing the Discussion section of the final article, adding their thoughts and suggestions to the various drafts. The article is accepted into a leading journal for publication. The primary researcher lists only himself as author of the article, claiming that he wrote at least 75% of the final paper.

Write a 350- to 700-word discussion of the following:

• Describe the ethical consideration(s) involved with the scenario.
• Has the primary researcher committed an ethical violation?
