comment How would synapses behave if resting potential was zero?
@ChuckSherrington just letting you know that your comment was flagged as "rude/offensive". :-) I think the joke that jonsca and Chuck are the same person may have been missed.

comment Are there any cognitive test (or test suites) available on the iPad?
On one of the pages, Joggle lists that is has many academic citations. Is this for Joggle's version of the task or for the task in general? Do you know of any academic references that have explicitly validated the Joggle implementation of these tasks?

comment What is the effect of scolding kids
I generally agree with what you say, but what is your evidence to support these claims? The challenge on this site is to provide theoretical or research evidence to support such claims.

comment How many samples are there when test subjects come through different recruitment strategies?
I think it's an interesting question. I agree that it reads like homework. @what given that it's not homework, then I congratulate you on writing creative questions to learn material. As a side point this site hasn't received a lot of homework questions, so we haven't really developed a policy on the topic. Personally, I think the general problem with homework questions is that they tend to be too specific (i.e., they don't create a general resource for the internet). In contrast, I think this is a general question.

comment Do we need a pre-test to compare the effectiveness of two treatments?
The key thing you mentioned in your question is "random assignment". In general, the choice of dependent variable does not change things. That said, when you get into a specific research context, different issues arise. For example, teaching interventions have their own features related to the mode of delivery in shared class rooms.

comment Psychometric scale with items in sets where responses imply a rank order of items
Could you further elaborate? What does it mean to give a response of 0, 1,2,3,4 or 5? What does M represent? What do the "x's" represent in your updated example?

comment Do measures of Big 5 personality have a positive bias towards extraverted, conscientious, emotionally stable, ageeable and open individuals?
Thanks. The article seems to provide standard psychometric information: i.e., the factor structure of the test, gender differences, whether test scores predict relevant criteria including job satisfaction and counter productive work behaviour; it doesn't directly seem to go into whether items have a positivity bias.

comment Why different responses to target and distractor in three-stimulus oddball procedure?
Just as a small side point, you are welcome to write an answer to your own question, particularly if it is well reasoned.

comment Does not using the brain erode its power?
What do you mean by (a) "practicing the brain"? and (b) "brain power"?

comment Are there “6 degrees of separation” for ideas?
Could you further explain how you see the 6 degrees of separation idea relating to the general issue of the brain or mind implicitly connecting ideas?

comment How to use Mechanical Turk for longer studies (i.e., 30 minutes+)?
@jeff It's good that it's possible, but I get the impression that there might be additional issues with longer studies around motivating participants to complete the task in the first place and ensuring that they perform the task conscientiously.

comment How to use Mechanical Turk for longer studies (i.e., 30 minutes+)?
@ofri I imagine speed of recruitment and cost effectiveness are the two main motivations. For example, If I could get 200 conscientious participants to complete a 30 minute study for US\$5 or US\$10 per participant, and it could all be finalised in a day or so, that would make my life a lot easier. mturk manages payment and it also manages the mapping of free time to tasks.

comment How to identify participants answering online questionnaires who have not paid attention?
You're right. I thought I remembered seeing a question like this before. It looks like I even answered it :-)

comment What is the conceptual relationship between higher order thinking and inductive reasoning?
@juilee interesting question. I encourage you to ask a separate question about this, perhaps with a link to this one.
