Three Guys Talking About Scales

What follows below is the result of an online discussion I had with psychologists Brent Roberts (BR) and Michael Frank (MF). We discussed scale construction, and particularly, whether items with two response options (i.e., Yes v. No) are good or bad for the reliability and validity of the scale. The answers we came to surprised me--and they might surprise you too!

MK: Twitter recently rolled out a polling feature that allows its users to ask and answer questions of each other. The poll feature allows polling with two possible response options (e.g., Is it Fall? Yes/No). Armed with snark and some basic training in psychometrics and scale construction, I thought it would be fun to pose the following as my first poll:

Said training suggests that, all things being equal, some people are more “Yes” or more “No” than others, so having response options that include more variety will capture more of the real variance in participant responses. To put that into an example, if I ask you if you agree with the statement: “I have high self-esteem.” A yes/no two-item response won’t capture all the true variance in people’s responses that might be otherwise captured by six items ranging from strongly disagree to strongly agree. MF/BR, is that how you would characterize your own understanding of psychometrics?

Thought Fragments Concerning Ideology in Social Science

I took a course in sociology my first year as an undergraduate at UC Berkeley. The course was an introduction to sociology taught by professor and social activist, Harry Edwards. The course blew me away because it felt so viscerally real. Professor Edwards would talk about social class, race, and gender in America and students would chime in about their own experiences that brought these big social constructs to life. What I learned in Professor Edwards’ class resembled nothing we had discussed in my high school history classes—I grew up in a politically conservative suburb in San Diego, and we didn’t have much ideological diversity in our discussions of law and society. Sociology, and social sciences more broadly, really spoke to me.

Parenthood can Take a Toll on Relationships, But it Doesn't have to

I became a parent a year and a half ago, and my life changed forever. When I was pregnant lots of parents gave me advice (Enjoy going to the grocery store by yourself while you still can! Go out on dates! Clean your house!). One even warned me that becoming a parent would “rock my world.” I thought I understood. I thought I was prepared for the huge change coming. And while I wasn’t unprepared, I really had no idea exactly how life-changing becoming a parent would be. Now I try to explain to my friends who don’t have children what exactly getting swept into parenthood felt like, and the best I have come up with is this—I had my daughter and she was more wonderful than I could have imagined, and the rest of my life fell into chaos. One of those pieces of my life was my relationship with my husband. We look at each other and marvel that we used to sit around on the weekend and lament that we did not know what to do with ourselves. Now we would give anything to learn the secret to freezing time. Now we try to hold on as life rushes by. Now I tell my husband we need more time and he agrees but asks, “what time?”

Teaching Undergrads vs. MBAs: Four Observations

Hello and sorry I've been away from blogging for so long! I ended up switching departments and jobs--now I work at Yale University at the School of Management. As you might imagine, a lot of things have changed as a result of the move. What I'd like to do today is to briefly summarize what stuck out to me as the main differences between teaching undergraduate psychology majors and first year MBAs.

A note of caution before we dive in: I've only spent about 27 hours teaching MBAs and three years teaching psychology undergraduates, so it's possible that I know little to nothing about teaching BOTH groups. Also, the undergraduates and MBAs experienced different courses and come from different universities, so the differences I observed might not reflect MBA/undergrad distinctions. What is reported here is simply one person's observations from a relatively short time period.

3 Ways Your Romantic Instincts Can Lead You Astray

When it comes to dating, we’re often told that we should trust our instincts: If it feels right, go for it, but if you get a bad feeling from someone, steer clear.

These instincts can certainly be helpful at times, but they’re also subject to a number of biases that can lead us to trust the wrong people and overlook the right ones.

Here are just three ways that our romantic instincts can lead us astray.

The Benefits of Capturing your Everyday Experiences

Source
What would you rather do right now, write down the last conversation you had or watch a funny video guaranteed to make you laugh? What about a month from now – do you think you’d rather read about a random conversation you had last month or watch another funny video? These are some of the questions researchers asked in a recent set of studies exploring our tendency to underestimate how much pleasure we get out of rediscovering mundane experiences. Participants in these studies consistently expected that they would not be very interested in rereading a log of an ordinary event in their everyday lives. But a couple of months down the road when the time came to reread that log, they found themselves much more interested and experienced more pleasure than they had expected. This was partly because they had forgotten a lot more of the event than they had expected they would! In the moment, we think why record our everyday experiences, we will remember them in the future and they aren’t that memorable anyway. Even just a month later though, our memories of the event begin to dim, the details fall away, and what once seemed ordinary feels a bit more extraordinary.

Gender Imbalance in Discussions of Best Research Practices

Over the last couple of weeks there have been some really excellent blog posts about gender representation in discussions of best research practices. The first was a shared Email correspondence between Simine Vazire and Lee Jussim. The second was a report of gender imbalance in discussions of best research practices by Alison Ledgerwood, Elizabeth Haines, and Kate Ratliff. Before then (May 2014), Sanjay Srivastava wrote about a probable diversity problem in the best practices debate. Go read these posts! I'll be here when you return.

SPSP 2015: Actually Predicting the Future

In regression (a common statistical practice used in social science research) we often attempt to predict the outcome of a given dependent measure (the DV) based on what we know about other measured variables theoretically related to the DV (the IVs). This common regression method has one problem though: We are predicting values for data that we have already collected. What if we were to engage in actual prediction? That is, what if we attempted to predict the values of a DV that is unknown? How might we do this and what would be the benefit?

This was a fascinating talk presented by Liz Page-Gould of the University of Toronto at the Future of Social Psychology Symposium!

SPSP 2015: Status Shapes Preferences for Redistribution

A lot of people think about political ideology as a powerful causal force that influences the structure of our society and our respective positions within it. In the politics and inequality symposium Jazmin Brown-Iannuzzi of the University of North Carolina, Chapel Hill and her colleagues examined political ideology from a different perspective: Instead of shaping the structure of society, does political ideology arise from our position within that structure? That is, do we create our political beliefs strategically in order to justify our own lives and the lives of those around us?

SPSP 2015: The world thinks that atheists are immoral

At the self and identity pre-conference this morning Will Gervais presented a series of studies (available open access right here) suggesting that people seem to automatically associate atheism with a lack of moral character.

SPSP 2015: The Contagious Spread of Affect

I was fortunate to attend the first session of the emotion pre-conference this morning and had a chance to hear about some amazing research conducted by Wendy Mendes (my post-doc advisor), Sara Waters, and Tessa West. The research examined the extent that affective states are transmitted between individuals.

The researchers reasoned that social living organisms are widely characterized by synchronous actions and states--with humans groups being particularly likely to synchronize their emotions and behaviors (here is a profound example of our capacity to synchronize during communal events).

SPSP 2015: We're here in Long Beach!

It's been a few months since I've posted on this blog, and I'm planning to change that over the next several days: It is time for the annual convention of the Society for Personality and Social Psychology and we've got three full days packed with social-personality content to share with the blogosphere. I'll be writing a few short posts over the course of the conference--but before I do I want to point out where you can find some of the current and former bloggers on this website, right here at the convention:
