You might want to read this review of social touch research: Thayer, S. (1986). History and strategies of research on social touch. Journal of Nonverbal Behavior, 10(1), 12-28.

comment What is the standard error of measurement for teacher made multiple choice tests?
In addition to difficulties in implementation, I think IRT is not applied in teacher constructed test settings because there is often an implicit contract with the students. That is, a student's mark is directly related to the proportion of items answered correctly. Thus, in IRT there is still the question of how thetas will be mapped on to exam grades. Of course this can be overcome, but I think it presents another obstacle to uptake, particularly where the test is used to make judgements about absolute performance and not just normative performance.

comment What is the standard error of measurement for teacher made multiple choice tests?
+1 I agree IRT (bayesian IRT in particular) provides a great framework for modelling multiple choice tests. In my particular case, I'm looking for heuristics that teachers might use to guide their decision about how many items to include in a test. I'd like to be able to give teachers a rough sense of how much more accurate their test could be if they for example increased their test from 80 to 100 items.

Standard error of measurement is the standard deviation that would be obtained if you were able to repeatedly obtain a measure for a particular individual under hypothetical identical circumstances. I.e., it's a measure of the uncertainty you have about a measure you have obtained on a person.

As a related topic you may want to read up about the evolution of emotions and arguments for their adaptive functions: en.wikipedia.org/wiki/Evolution_of_emotion

comment Should fantasy distractors be avoided in multiple choice questions
Can you clarify how you are defining "fantasy distractors"? Obviously without incorrect options, it would not be a test. But from your single example, I can't discern the exact distinction you are making between different types of distractors.
