I view software application training as, fundamentally, a combination of cognitive and motor skills. This line of research will impact the way I design my online tutorials.
Because so many of us read our blogs off of feeds rather than off of the site, I wanted to share Alvaro's comments in a post so that they aren't missed. He was kind enough to share Dr. Wayne Shebilske's response to his interview.
You can find Dr. Shebilske's paper at www.psychonomic.org/archive.
Wendy, thanks for such a nice summary. Happy that you enjoyed the interview.
Wanted to let you and your readers know that the US-based professor doing some replication studies based on Prof. Gopher's work came to the site and left a very useful comment, which I copy here
"Your excellent interview with Dr. Gopher reminded me why so many of us have followed his lead in training complex skills. I hope that your interview inspires others. They will find that he is generous with his ideas, time, energy, and infectious positive spirit. Working with him to replicate experiments and extend ideas is both productive and enjoyable.
Your interview includes a reference to an article by my colleagues and me. I want to update the reference and provide a related reference to a Web-based Archive.

The journal article's abstract describes both:
We describe briefly the redevelopment of Space Fortress (SF), a research tool widely used to study training of complex tasks involving both cognitive and motor skills, to execute on current generation systems with significantly extended capabilities, and then compare the performance of human participants on an original PC version of SF with the Revised Space Fortress (RSF). Participants trained on SF or RSF for 10 sets of 8 3-min practice trials and 2 3-min test trials. They then took tests on retention, resistance to secondary task interference, and transfer to a different control system. They then switched from SF to RSF or from RSF to SF for two sets of final tests and completed rating scales comparing RSF and SF. Slight differences were predicted based on a scoring error in the original version of SF used and on slightly more precise joystick control in RSF. The predictions were supported. The SF group started better, but did worse when they transferred to RSF. Despite the disadvantage of having to be cautious in generalizing from RSF to SF, RSF has many advantages, which include accommodating new PC hardware and new training techniques. A monograph that presents the methodology used in creating RSF, details on its performance and validation, and directions on how to download free copies of the system may be downloaded from www.psychonomic.org/archive/.
The extended capabilities for RSF include a) being executable on current generation platforms, b) being written in a mostly platform independent manner, c) being executable in a distributed environment, d) having hooks built in for the incorporation of intelligent agents to play various roles, such as partners and coaches e) providing a general experiment definition mechanism, f) supporting teamwork through being able to flexibly assign different input controls to different members of a team, g) maintaining all data in a central database rather than having to manually merge data sets after the fact, and h) having playback capability, which enables researchers to review all actions that occurred during an experiment and to take new measures. Experimenters can design measures before an experiment to test specific hypotheses with a rigorous laboratory task. They can also use playback to discover and explore unanticipated events. Although simpler and more complex synthetic task environments can be advantageous for some goals, Danny Gopher, our colleagues, and I believe that Space Fortress remains an important tool for scientists and trainers.
