Recently, there has been considerable controversy regarding the role of genetically modified foods and pesticides as contributing to many illnesses including the risk associated with autism.  One digital news blurb equated pesticides as causing autism.  Develop an experimental study that helps to answer whether pesticide exposure of pregnant mothers cause autism in their offspring.  What ethical issues might arise in conducting this type of research?

Recently, there has been considerable controversy regarding the role of genetically modified foods and pesticides as contributing to many illnesses including the risk associated with autism.  One digital news blurb equated pesticides as causing autism. Develop a correlational study that helps to answer the relationship between pesticide exposure of pregnant mothers and autism in their offspring. What ethical issues might arise?

When conducting various types of research studies, concerns regarding external and internal validity are warranted.  Define and provide examples of all the threats to validity.  How might reducing these threats to validity increase confidence in the findings of study that makes claims that a particular type of intervention (therapy or medication) is effective in reducing symptoms of severe emotional reactivity and dysregulation?
