I am a Lecturer in the School of Psychology at Deakin University bridging I/O psychology and statistics.

I'm quite active on the Cognitive Sciences and Statistics Stack Exchanges.

comment Intelligence and marriage satisfaction
@what Thanks for the Lewak reference. I guess the degree to which women are concerned about status in spouse selection is an empirical question. It would be interesting to see how concern for status varies between men and women and whether it has changed over the last 50 years or so.

comment Should questions in psychology always be objective questions?
Also, as a side point, I hope this question doesn't get closed, because I think it has yielded a couple of hopefully reasonable answers, and the broad question itself is quite interesting, even if it does raise several definitional issues before it can be answered.

comment Should questions in psychology always be objective questions?
@Nick People have different heights. People have different favourite colours. Individual differences does not define subjectivity. Of course you could scientifically explore the meaning of "favourite colour". E.g., are people consistent in their rating? Does it vary by culture? Does it correlate with other behavioural evidence of colour preference?

comment What is the relative effectiveness of self initiated versus therapy approaches to repairing damaged body schema?
(1) Could you clarify what you mean by damaged body schema? What types of damage are you interested in? (2) Would you be able to add a couple of the references to the studies that you've read to make the question more useful for others?

comment Why does speaking disrupt rhythm?
An additional observation: In order to sing and play an instrument at the same time I needed to ensure that I both understood the rhythm of the melody and the rhythm of the music and that I was able to align the two to a common beat.

comment What is the standard error of measurement for teacher made multiple choice tests?
With regards to absolute performance: I agree that making claims about absolute performance from a test in a rigorous way is very difficult. But ultimately any teacher who is asked to decide what is the passing grade is forced to draw an absolute line in the sand somewhere. This might be a particular value of theta or a proportion correct on a test. My guess is that many teachers feel more comfortable talking about proportion correct (e.g., less than 50%, 60%, or whatever is the custom is a fail).

comment What is the standard error of measurement for teacher made multiple choice tests?
With regards to heuristics: Any heuristic would be based on the assumption that the teacher would be writing a set of additional items of roughly comparable quality, difficulty, and variety as the existing items. I acknowledge that some teachers might differ in their skill in doing this, but at the same time, a heuristic could be frame in terms of a ball park or a typical range.

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.

comment What is the standard error of measurement for teacher made multiple choice tests?
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.

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.

comment What is it called when a student tends to speak about what he knows?
It sounds a bit like framing/reframing. Politicians and job applicants do it all the time.

That sounds interesting. Any thoughts about how your theory of gut instinct might be applied to the OP's context of answering questions on an IQ test?
