Within&Between Podcast

A podcast about the methods and metascience of developmental science, cohosted by Jessica Logan @jarlogan and Sara Hart @saraannhart. We talk about developmental sciencing, including data collection, data analysis, research methods, and open science, as well as life in academia. Think about it like a lab meeting where you don’t have to do the readings and never have to present. ​

    S3E9: What is Heritability Anyway?

    44:35

    In this episode, Jess and Sara finally (Finally!) tackle the basic premise of behavior genetics. We talk about what kinds of research questions you can ask with genetically sensitive designs, describe what heritability is and what it’s not, and discuss just how it’s possible that scientists can use data from twin pairs to understand how much of the variance in some skill or behavior is due to genes and how much is attributable to the environment. A lot of that estimate depends on just how much genes and environments vary within a twin pair and between twin pairs (see what we did there?). In this episode we talked about: Sara’s paper with the figures that Jess describes: https://www.nature.com/articles/s41539-020-00079-z/figures/3 Here’s a cool introductory paper written for Frontiers for young minds that covers much of this introductory content: https://kids.frontiersin.org/articles/10.3389/frym.2019.00059 Connect with the podcast on twitter @within_between, or email us letters about developmental science at [email protected] More episodes and podcast information at WithinandBetweenPod.com.

    3E8: Planned Missing Data - This Cell Intentionally Left Blank.

    54:40

    If you’ve ever had to deal with missing data, you’ve probably wished you could avoid it completely in the future. So why on earth would anyone design a study where data are missing on purpose? When you set up a project, there are actually several advantages to selecting a subset of people to skip assessments, items, or waves on purpose. Jess and Sara describe those designs here, and just what the advantages are, as well as fun future directions for one specific subtype of these designs: The two-method measurement planned missingness design. Even though we start with a basic missing data overview, and you might think that missing data is scary or boring, we SWEAR this one is interesting. Links mentioned in this episode: The preprint on how to handle missing data decision tree: https://psyarxiv.com/mdw5r/ The paper that introduces the longitudinal version of the two method measurement design: https://doi.org/10.1177/0165025414542711 Menglin Xu and Jess’s paper in JREE: https://www.tandfonline.com/doi/pdf/10.1080/19345747.2021.1875528 Overview of different types of planning missing data designs in education research:  https://doi.org/10.1080/00461520.2016.1208094 Connect with the podcast on twitter @within_between, or email us letters about developmental science at [email protected] More episodes and podcast information at WithinandBetweenPod.com.

    S3E7: Parts of a Grant Budget

    1:11:06

    Why do you write a grant? To get money to do some sort of project of course! But how do you figure out how much money you need? Through a grant budget! But what goes into a grant budget? All kinds of things that you might expect (e.g., cost of the materials you need) and some things that you maybe don’t (e.g., Indirect costs). How can I find out what those budget-y things are and what they mean? You’re in luck, friend. That’s what Jess and Sara talk about for this whole episode! But Jess, why did you structure this whole show note blurb as questions and answers? Playing around with different narrative structures is both fun AND informative.

    S3E6: Preregistrations

    1:05:54

    Preregistration is writing down your idea for how you plan to collect and analyze your data _before_ you actually start collecting or analyzing it. In this episode, Jess and Sara talk about the many benefits of preregistration, the differences between preregistration and registered reports, describe their experiences with it, discuss some resources, and (hopefully) put to rest some fears about the practice that you might have. Some resources we mention in this episode: Sara’s blog post on preregistration: https://www.womeninedresearch.com/news/preregistrations Paper Sara was thinking of when she talked about the distribution of p-values between preregistered and not preregistered work (it’s really the distribution of effect sizes): https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6470248/ Garden of forking paths: http://www.stat.columbia.edu/~gelman/research/unpublished/p_hacking.pdf Preregistration templates at OSF: https://osf.io/zab38/wiki/home/ Connect with the podcast on twitter @within_between, or email us letters about developmental science at [email protected] More episodes and podcast information at WithinandBetweenPod.com.

    S3E5: Trajectories have variance too!

    41:26

    Trajectory of heritability to the heritability of trajectories? Measuring growth in skills and abilities over time is practically (maybe literally!) synonymous with developmental science. In this episode, Jess and Sara talk about how static measurements of a skill can have different variance, and different predictors, from growth in that skill. After a general discussion, we dive into how that plays into estimates of heritability, and the difference between the trajectory of heritability and the heritability of trajectories. Our Response paper: https://psyarxiv.com/qtwhg/ Uchiyama and colleagues “Cultural Evolution of Genetic Heritability” from 2021.  Behavioral and Brain Sciences Paper mentioned that examined the heritability of general cognitive ability across ages.

    S3E4: You are the search committee

    1:05:48

    In this episode, Jess and Sara talk about what it’s like to serve on an academic search committee. To those of you who are about to serve on a committee (maybe for the first time), we will take you through the whole process from writing the call to making the offer. Or those of you on the market this year, peek behind the curtain. Every search is different! Things happen very differently from university to university, and even from search to search. We want this overview to give you, the search committee member, the permission to speak up and suggest changes from the way it may have been done before.

    S3E3: All about that LDBase

    52:23

    In this episode, Jess asks Sara to talk about LDBase, the data repository she has been building designed specifically to hold developmental science data. We discuss what LDbase is, what motivated her and her colleagues to start building it, what makes it unique, and how it works. Sara even describes several excellent resources you can find on the website that make data sharing easier. Go see it for yourself at www.LDBase.org All about integrative data analysis: Curran, P. J., & Hussong, A. M. (2009). Integrative data analysis: the simultaneous analysis of multiple data sets. Psychological methods, 14(2), 81. https://pubmed.ncbi.nlm.nih.gov/19485623/ Check out a paper by Sara’s team on a cool use of integrative data analysis https://psyarxiv.com/xqbc5/ Connect with the podcast on twitter @within_between, or email us letters about developmental science at [email protected] More episodes and podcast information at WithinandBetweenPod.com.

    S3E2: What’s up with Els*vier?

    52:49

    You may have noticed that the cycle of academic publishing is pretty broken. Scientists give their research papers to academic journals for free, then the journal puts that work behind a paywall. Sometimes institutions will pay for a package of subscriptions to these journals, often costing millions of dollars. Jess and Sara talk about this cycle, and how institutions, journals, and individuals have started to push back against it.

    S3E1: Methodologists? What are those?

    1:07:47

    In this episode Jess and Sara talk about the role of methodologist in developmental science, and how it’s different from a statistician. A methodologist is a content expert and a collaborator like any other, and we do our best work when we’re involved right from the initial planning stages of a project. Why? Because nearly every decision made in a research project can have implications for statistical conclusions, and methodologists are the collaborators who keep this in mind. Think you might be interested in being a methodologist? Jess and Sara give some suggestions on how to prepare and frame your materials.

    Season ALMOST 3 : Burnout.

    48:41

    Well the spring 2021 semester is over, and - what is this feeling? We’re a little (a lot) overwhelmed. Jess and Sara describe their experiences, and theorize a bit about why it might be particularly bad right now. Is the pandemic over here in the US? What does that mean for our jobs? That feeling of one day more can sometimes be too much. We end by suggesting, maybe, we all need a break, and to give ourselves, and our colleagues, some grace. Ed Yong’s article about the “end” of the pandemic in the US: https://www.theatlantic.com/health/archive/2021/05/pandemic-trauma-summer/618934/ The Seven Year Postdoc: https://blogs.scientificamerican.com/guest-blog/the-awesomest-7-year-postdoc-or-how-i-learned-to-stop-worrying-and-love-the-tenure-track-faculty-life/ A few articles about burnout: https://www.insidehighered.com/advice/2020/04/28/advice-faculty-help-them-avoid-burnout-during-pandemic-opinion https://www.chronicle.com/newsletter/teaching/2020-05-21?cid2=gen_login_refresh&cid=gen_sign_in https://www.psychologytoday.com/us/blog/high-octane-women/201311/the-tell-tale-signs-burnout-do-you-have-them Does anybody have a map - does anybody maybe happen to know how the hell to do this? I don’t know if you can tell but this is me just pretending to know.
