Wk2 Assignment1 Discussion Paper

Prior to beginning work on this discussion please read the Hurley  (2013) Trait vs. Fate and Weaver, et al. (2004) Epigenetic Programming  by Maternal Behavior articles and review the Webster “The Great Rat  Mother Switcheroo” online article. The recommended resources for this  week also provide more information on these topics.

In  this week’s required resources, we have learned that while our genes  have a lot to say about who we are, environmental factors, particularly  parental behavior, can shape the behavior of offspring on a biochemical  level.  Using the assigned Hurley and Weaver et al. articles, briefly  describe the research that has been done with rat mothers to illustrate  this phenomenon. In your initial post of a minimum of 350 words, explain  the implications of the research on parental behavior and environmental  factors as they relate to human personality development. Describe how  this research data might be used to explain unhealthy personality  traits. Describe how the emerging field of epigenetics is impacting the  longstanding nature vs nurture paradigm. Be sure to cite the Hurley and  Weaver, et al. articles in your initial post.
