Week 7 Do Genes Cause Behavior? II: Phenotype Teams

This week, you’ll take your methodological expertise developed in Week 6 and rotate into phenotype-based teams, to bring together a variety of different methods to understand a particular phenotype.

Team assignments will be posted on Moodle.

Objectives

  • Understand how a variety of different methods can address the same topic.
  • Synthesize research across methods to identify areas of common agreement, limitations of one method addressed by another, and areas where the different approaches disagree.

Lecture Notes

This week our goal is to apply a variety of genetically informative methods to understanding what causes (or is caused by) a particular phenotype.

As soon as possible:

  • Check your team assignment.
  • Make sure you can access your team discussion forum for Week 7 (posted in Moodle below your team’s pre-selected readings).
  • Make sure you can access (or request access to) your team google doc for Week 7 (posted below your team’s discussion board; access to the doc does require a login so I can see who contributed what).
  • Skim your team’s pre-selected papers (note: SKIM, you are not expected to do a deep-read of all of these).

This week we will have Zoom meetings on both Tuesday and Thursday (11:00 am - 12:20 pm Central). During these sessions, you will work together to:

  • [Tuesday] Complete article summaries for some of your pre-selected papers, starting from what was accomplished last week when the methods teams were working with the same readings.
  • [Thursday] Assemble a Topic Summary about your phenotype, focusing on the question(s): What causes (or is caused by) your team’s phenotype?

As always, there are four asynchronous options to contribute to your team effort this week. However, I encourage you to attend this week’s Zoom sessions if at all possible, because working through these activities as a group is the easiest way to develop these skills.

The readings for Week 6 and Week 7 are essentially the same. Last week, you developed expertise by examining how a specific method has been applied across many phenotypes. This week, your goal is to synthesize research from across a variety of methods to develop your understanding of how your team’s phenotype fits into a complex network of potential causal influences.

Prep Work

  • Skim the papers posted on your team’s resources list below
    • Your team will be working together to create formal summaries of these papers during Tuesday’s Zoom session, but you should become generally familiar with them before/even if you’re not attending Tuesday’s Zoom session. Each team starts with 4-7 empirical papers applying one or more methods we covered in Week 6.

Participation Activities

  • Find an empirical article (other than those that have been pre-selected) about the genetics of your team’s phenotype, fill out an Empirical Article Summary template, and post your summary to your team’s discussion forum. Make the subject of your post: [summary] Article title (N = number of participants).
  • Find a popular media piece about the genetics of your team’s phenotype, find the published journal article that it is reporting, and post both to your team’s discussion forum. Make the subject of your post: [scicomm] Popular media piece title
  • Write a tweet thread (4 or more tweets, <280 characters each, link/image/gifs optional) about the genetics of your team’s phenotype (citing the pre-selected readings and/or papers that have been posted to your team’s discussion forum) and post it to your team’s discussion forum. For some inspiration, check out this twitter list of authors whose work you have/will read in this class, plus some of my favorite scicommers. Make the subject of your post: [tweets] First few words of the first tweet.
  • Journal: Editing
    • Do some editing of your team’s Topic Summary draft (in the team google doc, produced during the Thursday live Zoom session). For example:
      • Add information from posts in your team’s discussion forum.
      • Add details about individual studies to existing text: sample sizes, participant characteristics, phenotype operationalizations, effect sizes, replication attempts.
      • Paraphrase direct quotes; only quote something directly if the original phrasing was so perfect and beautiful that to rephrase it would be a crime against language.
      • Work through one or more of the steps of Randy McCarthy’s suggestions for self-editing your writing to edit your team’s Topic Summary draft.
    • For participation activity credit: Write a couple of sentences here reflecting on what you changed or added and how those changes impact the summary overall.
  • Team Learning Project on Tuesday, 11:00 am - 12:20 pm
    • Using the article summaries generated in Week 6 as a starting point, work together to fill out Empirical Article Summary templates describing your team’s pre-selected papers. Each team starts with 4-7 empirical papers applying one or more methods we covered in Week 6.
  • Team Learning Project on Thursday, 11:00 am - 12:20 pm
    • Work together to draft a Topic Summary about your team’s phenotype.
