I spend a lot of time writing and answering email. Email is, according to timing, the third longest activity on my computer (although I am using three computers and can check this only on one of them – #timing please let us link computers for an overall analysis) … anyway – back to no email – as a holiday treat I decided to shut down all my email accounts 5 days before Dec. 24th and promised myself not to touch them until Jan. 11th. It turns out that I will come short one day of this plan. Nevertheless, I am quite happy with the result and the positive effects of this email absence. Needless to say that reading emails during vacation brings you back into a working mood (or never lets you out of it), not reading email had positive side effects before (I did this twice in the last 20 years of ‘doing’ emails). Many issues that come during such a break often solve themselves without intervention or can be solved quickly within a few hours after being back in the email world.
Well, I will turn on my email accounts now and see how much work has piled up … BRB.
So, 380 emails later – a paper submitted by a co-author, a rejection for a previous submission, a talk accepted, a chapter revised by a co-author – the best part of all this is that dealing with a ton of mails is a very quick thing, with a relatively low threshold for simply deleting out of date emails or replying quickly to urgent matters. What’s left are some longer replies I will do now …
Happy New Year!
Cilia Witteman and Nanon Spaanjaars (my dutch connection) worked together on a piece on whether psychodiagnosticians improve over time (they don’t) in their ability to classify symptoms to DSM categories. This turned out to be a pretty cool paper combining eye-tracking data with a practical, and hopefully, relevant question.
Schulte-Mecklenbeck, M., Spaanjaars, N.L., & Witteman, C.L.M. (in press). The (in)visibility of psychodiagnosticians’ expertise. Journal of Behavioral Decision Making. http://dx.doi.org/10.1002/bdm.1925
This study investigates decision making in mental health care. Specifically, it compares the diagnostic decision outcomes (i.e., the quality of diagnoses) and the diagnostic decision process (i.e., pre-decisional information acquisition patterns) of novice and experienced clinical psychologists. Participants’ eye movements were recorded while they completed diagnostic tasks, classifying mental disorders. In line with previous research, our findings indicate that diagnosticians’ performance is not related to their clinical experience. Eye-tracking data pro- vide corroborative evidence for this result from the process perspective: experience does not predict changes in cue inspection patterns. For future research into expertise in this domain, it is advisable to track individual differences between clinicians rather than study differences on the group level.
Andrew Gelman talked about a really old paper I did together with Anton Kühberger ages ago. It was actually the first paper / ‘real’ scientific project I was involved in.
It generated quite the buzz over its 20 year lifespan and was cited a whopping 13 times (stats look good without y-axis) …
Going back to it, I was happy to see that we already talked about replication (and were very reluctant to push the button harder – as we would have not been able to get through the reviews, I guess) … Things have changed.
The friendly people from RStudio recently started a webinar series with talks on the following topics (among others):
Data wrangling with R and RStudio
The Grammar and Graphics of Data Science (both dplyr happiness)
RStudio and Shiny
… and many more.
Our friend Dr. Nathaniel D. Philipps also started a cool R course with videos, shiny apps and many other new goodies.
Recently Ryan Murphy and myself realised that a startup here in Berlin features ideas of our 2011 Flashlight paper.
Well, the guys at attensee.com did a great job taking the idea we had much further we ever thought one would be able to take it …
Here is a feature I totally love – a live heat map of what you are looking at … awesome!
dplyr is the new plyr – and it is awesome!
fast, consistent and easy to read … check out a set of instructional pages, presentation and videos here
Thanks Hadley Wickham
Mal was Längeres zu unseren Lieblingsthemen: Essen und Entscheidungsforschung … Enjoy!
Schulte-Mecklenbeck, M., & Kühberger, A. (2014). Out of sight – out of mind? Information acquisition patterns in risky choice framing. Polish Psychological Bulletin, 45, 21–28.
I teamed up with Anton Kühberger to write about one of our old, favorite topics: framing and process tracing …
Here is the abstract:
We investigate whether risky choice framing, i.e., the preference of a sure over an equivalent risky option when choosing among gains, and the reverse when choosing among losses, depends on redundancy and density of information available in a task. Redundancy, the saliency of missing information, and density, the description of options in one or multiple chunks, was manipulated in a matrix setup presented in MouselabWeb. On the choice level we found a framing effect only in setups with non-redundant information. On the process level outcomes attracted more acquisitions than probabilities, irrespective of redundancy. A dissociation between acquisition behavior and choice calls for a critical discussion of the limits of process-tracing measures for understanding and predicting choices in decision making tasks.
