The Reproducibility Project: Psychology

There is a great article in the Weekly Standard titled Making It All Up, the Behavioral Sciences Scandal about how over 60 percent of published results in the field of Psychology are not reproducible. Here and here are articles from the journal Nature on the same subject along with another one from the journal Science. I sent my daughter, Kelly a link to the articles. She is working on a PhD in Marketing at University of Washington and takes research methodology classes from both the Sociology department and the Psychology department. Replicability is a big topic in those classes. Kelly made the argument that research done in marketing does not suffer from the same problem as in the social sciences or even the hard sciences because the measure of the quality of the research is whether more stuff gets sold. That is the point–selling stuff. So if the research does not lead to new insights into how to sell stuff, the funding dies. I think I might buy that idea. But then again, it was a Marketing researcher who told me that.

Christian presents his research

Christian at Logan Airport, Boston on MIT Lincoln Lab visitIf I have the time right, Christian, at this very moment, is presenting his Information Theory research at MIT Lincoln Laboratory. This is the first time he has done this kind of formal presentation (with a tie and all that). It is the culmination of a full year of research in a brand new (to Christian) area of Mathematics and Electrical Engineering. Lorena and I are on pins and needles waiting to hear how it went. If all goes well, this should eventually turn into a refereed conference paper and, with expanded research and content, possibly even a refereed journal article.

The next step after will be his “quals” presentation which will be this same research work but to his doctoral committee back at Arizona State. I am not sure what happens after that, but it probably has something to do with preparation for “prelims” or “comprehensive exams” which are usually pretty challenging.

What you learned in Kindergarten is still important

Christian PowerPoint slide for Lincoln Labs presentationChristian is scheduled to fly to Boston tomorrow to give a talk on his research. He has all the technical material well in hand and a well organized presentation. Not so amazingly, one of his biggest challenges is to create professional and compelling PowerPoint slides that convey his ideas. It seems like none of the tools commonly used to create graphics for the slides have improved very much or gotten any easier to use in the last twenty years.

Christ has been creating these kinds of presentations for a long, long time. I bought the kids a desktop publishing program called Microsoft Publisher when Kelly was twelve and Christian was ten. You can see some thumbnails of the magazine they published below. Christian is fluent in the use of LaTeX, Inkscape, GIMP, GnuPlot and other graphical tools, but it seems like the tools of choice are MatLab, Excel and PowerPoint. It makes a whole lot of sense to use better tools than MatLab and Excel to create graphs (R is great), but every institution has their favorite PowerPoint template so he is probably stuck with that.

Christian at the Spring 2013 NCSU Undergraduate Research Symposium

Day 597 of 1000

Christian at the Spring 2013 NCSU Undergraduate Research SymposiumChristian dressed up today to go to the McKimmon Center at NCSU to show off a poster he made for the Spring 2013 Undergraduate Research Symposium. He made the poster for his work at NCSU’s Optical Sensing Laboratory where he is designing, building, and characterizing a Black Body Source for infrared camera and spectrophotometer calibration under the Tutelage of Dr. Michael Kudenov.  I think Christian was a little nervous when the thing got started, but he texted me that a lot of his buddies were there with him, doing the same thing.

Christian did not really have much to show because this is the first semester of a two semester project.  He is just getting started building the device and has programmed (in assembly language) some basic functionality into it.  When we get back from California at the first of June, Christian will devote about six hours per day to this project until it is complete.  He hopes to be able to present some good data and a manual that explains how to build and use the device.  The big deal about what he is doing is not so much about what it does, but what it does for less than $1000.  I am looking forward to seeing how this all turns out.

Christian’s first undergraduate research poster

Day 593 of 1000

Christian's undergraduate research posterChristian created the poster in the image to the right to describe his undergraduate research.  This is first of the two semester he will spend working on the project.  A poster is required for each semesters.  He will present the poster and describe his work for the poster at a symposium on Wednesday morning.  Here is the poster abstract:

Spectrophotometers and infrared cameras are widely used for non-contact temperature detection. These devices have been applied to manufacturing processes monitoring in industry Bnight or smoke vision systems for the police, firefighters, and military, and many other places. However, the sensors need to be calibrated to their surroundings to collect useful information. This calibration can be performed by metering the camera with respect to a light-absorbing surface with constant temerature and constant electromagnetic emissions.  This project involves building and testing a planar metering source for the described equipment which maintains enough temperature precision to allow accurate temeprature calibration while maintaining lowcost.
