Your question is referring to display polarity. A positive polar display consists of dark letters on a light background, a negative polar display consists of light letters on a dark background. Polarity by itself is independent of text-to-background contrast, as you rightly state. Generally, positive polarity facilitates performance (e.g. Buchner & ...

The Wikipedia article no longer makes reference to the phenomenon that you quote (to my inspection), so I'm not entirely sure if that assertion was edited out as an inaccuracy on someone's part. I did find some information on visual perception and high frequency flicker that might point to some of the significance of the 60 Hz refresh rate of a monitor. At ...

Preface This is a very interesting question, that is also somewhat related to my area of research. I know of several related results (which I might add later in an edit), and I thought that with a few minutes of scholar search I'll find a paper dealing with this question exactly. I was surprised to find no such papers. So I decided to conduct an ...

Depending on your exact definition of what you call a "context switch" there is some research available. There is plenty of research on a more high-level (multi-tasking) definition of context switches. Usually when I read about context switches they refer to this higher level concept, unlike the study you linked to which compares the cost of switching ...

I don't know of any well-validated general short scales. Here are a few thoughts: A major distinction is between self-report versus ability based measures. Self-report measures will ask the participant to rate their knowledge, skills, and experience. Ability based measures will require demonstration of competence. If you are limited to "self-measures", ...

There is indeed some research on handedness and user interfaces but not exactly at the level you seem to be after. Handedness matters for tablet interfaces, hand occlusion is a particular concern there. Some references: http://hal.inria.fr/hal-00670516/en and http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.89.4546 Speculating myself a little bit, I ...

It looks like there is some empirical evidence that passphrases are easier to remember than either random passwords (not surprising) or user-selected short passwords after standard advice to use mix of upper and lower and avoid words. http://homepages.cs.ncl.ac.uk/jeff.yan/#exp Thanks Jeff for the pointer in a comment (same Jeff?).
