Benefits of soy diet or organic food diet on physical and cognitive development

Psychology homework help
Consider the following: Many products, diets, and services are marketed to parents as beneficial to infant or toddler development. In order to increase sales to parents and caretakers, some companies use marketing strategies that make exaggerated, unfounded, or unrealistic claims about the effects of their product(s) on child development.
Select one claim that you suspect to be exaggerated or false (your research may in fact show the claim has validity). Describe in detail what the advertised product, diet, or service is supposed to do. Some examples include:

  • Educational videos related to language development
  • Effects of classical music on cognitive development
  • Benefits of soy diet or organic food diet on physical and cognitive development
  • Service promising to teach your 18-month-old how to read
  • Any other claim made by a manufacturer or service provider, aimed at enhancing infant or toddler development

Write a 1,050- to 1,400-word paper addressing the following:

  • What area or areas of development does the product, diet, or service claim to enhance?
  • Use the University Library to investigate the claim. What does the published literature say about the issue you are investigating? What does the research reveal about how to promote healthy development in this area? What does this reveal about the necessity and actual benefits of the product, diet, or service?
  • Is there any evidence to support the claim? Why or why not?
  • Imagine that a licensed psychologist in your state publically endorsed a product with no empirical evidence supporting its claims.  It was later discovered that the psychologist was receiving a percentage of money from the sale of the product to parents.  Is this a violation of the APA Code of Ethics?  Explain.  Be sure to cite the appropriate section or sections of the Code in your response.

Investigate the claim using your textbook and a minimum of four additional scholarly sources (such as peer reviewed journal articles).
Format your paper consistent with APA guidelines.
Note: You may not find a peer-reviewed journal article on a specific product, diet, or service. However, you will most likely be able to find peer-reviewed journal articles on the general issue that you are investigating. For example, if you are investigating educational videos that claim that cognitive skills in infancy are enhanced by using a particular approach or method, you can then review and evaluate studies that focus on enhancing cognitive skills in infancy. Review the evidence for and against the use of specific techniques and summarize your findings.

How can our society reconcile differing views about the ethics of using biotechnology

Biology homework help
Topic 1. Societal Aspects of Human Gene Editing. Read the letter-to-the-editor to a newspaper by Dr. Cox, in which he states an opinion about the use of CRISPR for human gene editing.

  • (a) In your own words, what is the main point that Dr. Cox is trying to make?
  • (b) How can our society reconcile differing views about the ethics of using biotechnology? Explain.

Topic 2. Societal Aspects of Gene Drives in Wild Populations. In the article by Zimmer (2017), Kevin Esvelt says that he made a huge mistake by championing the application of a technology that he now says is far too dangerous to actually deploy. In a post of about 125 words, address the following:

  • (a) What is the technology that he championed? What does it consist of and why does he think it’s too risky to use outside the lab?
  • (b) In your opinion, what sorts of laws and regulations, if any, should society put into place to regulate the technology that Esvelt regrets championing?

Topic 3. Pedigrees for Traits that are Controlled by a Single Gene. While most human traits are controlled by more than one gene, a subset of them are controlled by a single gene for that trait. In such cases, the pedigree can be useful in determining the mode of inheritance, such as autosomal dominant, autosomalrecessive, or X-linked recessive. The document Pedigrees.pdf **  contains the pedigree for three different traits from the same family: Trait 1, Trait 2 and Trait 3. In each pedigree, individuals with the trait are shaded. These pedigrees follow the usual conventions for pedigrees: squares are males; circles are female; offspring are drawn under each mating pair. See book for details.

  • (a) Which of the three traits (Trait 1, Trait 2, Trait 3) follows an X-linked recessive pattern of inheritance?
  • (b) Which clues from the pedigree support your conclusion?
