From the School of Computer Science and Department of Psychology at McGill University, I marvel at the world through algorithmic lenses. My specific interests are in quantum computing, evolutionary game theory, modern evolutionary synthesis, and theoretical cognitive science. Previously I was at the Institute for Quantum Computing and Department of Combinatorics & Optimization at the University of Waterloo and a visitor to the Centre for Quantum Technologies at the National University of Singapore.

comment Visual search: complexity of positive vs negative search tasks
@vizzero thanks for the suggestion, but the goal of my answer was to point out that there is a distinction between parallel and sequential processing of information in search tasks (as was pointed out by Treisman in 1985). If you follow the references forward, you can find further examples. The testing section is just a long-hand way of explaining how constant-factor equivalence (and basic asymptotic analysis) works, and how you could start to check parallel-vs-serial in an experiment. Note that this is a pretty standard way to do these tests.

comment Is this optical illusion the visual equivalent of binaural beats?
@BenBrocka I don't think the OP meant 'similar' as in 'using the same neural mechanism' but as 'producing similar qualia in a different domain (i.e. visual instead of auditory).

comment For depression diagnoses, does one make a clear distinction between endogenous and exogenous causes of depression?
the two are often coupled. Also, you make more than endogenous and exogenous in your distinction. Your first is about the brain, your second is about the mind (well, even further: mind in social context). I would try to make the scope be of the same field. I.e. at least adjust your endogenous reasons to mind-centered/psychological ones and do not try to talk about the brain directly. Especially when you are asking about psychiatry (also, good tag to add to this question).

comment What article reported variability in supporting hypotheses across disciplines?
why not just edit the figure into @Xurtio's answer?

comment Does the Sapir-Whorf hypothesis apply to artificial (specifically programming) languages?
@ChuckSherrington if this was a question about programming languages wouldn't that relate to io-psych? Since organizations would be interested in optimizing what tools they give their programmers? We can discuss this in detail in chat. As is, I think the question is fine with the linguistics and maybe language tag. Here are 1, 2, 3 related questions; we could steal some tags from them. I recommend philosophy-of-mind.

comment Does the Sapir-Whorf hypothesis apply to artificial (specifically programming) languages?
NLP as in Natural Language Processing is also not an appropriate tag for this question. If by 'artificial languages' the OP means 'programming languages' and how they effect how we design/implement/reason-about algorithms, then he should write programming languages, and the io-psych tag would be relevant. But usually 'artificial languages' means languages that are created artificially for normal conversation (say Klingon, or Esperanto). Which do you mean @Roly?

@H.Muster not-X is almost always a more difficult task than X.

comment How does a researcher typically go about conducting a survey-based psychological experiment?
I also moved the motivation after the question, since you suggested that you want general info, not high-heels specific. If you feel this is inappropriate, you can always roll-back my edits.

comment How does a researcher typically go about conducting a survey-based psychological experiment?
I think the securing funding part is a completely separate question. I don't see what would be special about a survey-type experiment in terms of securing funding (except that you need much less funding). The appropriate-design of the experiment cannot be answered without knowing which experiment you want to conduct and what you expect to measure.

comment Visual search: complexity of positive vs negative search tasks
@H.Muster I am not saying she explained it in terms of task difficulties, I am suggesting that her work makes my assumption "a reasonable one". In that there are two types of processing observed: highly parallel pre-attentive and serial post-attentive. I think my answer is structured pretty poorly right now, and I will try to restructure by moving the Treisman answer to the top and my conjecturing and analogies below.

comment Visual search: complexity of positive vs negative search tasks
this is not a fair comparison between human and computer. You are allowing a human to do parallel processing in the first case by saying "thus can be seen immediately" while you force the computer to do only sequential processing. This would be a poor model.

can you give a quick summary of what the Suddendorf & Corballis group typically conclude?

comment Is it possible to distinguish recall and calculation?
@fgregg sometimes the types/frequency of mistakes can be used to understand how individuals represent/process information (apart from timing data). The most famous example of this is the study of how beginner versus expert chess players memorize and recall chess positions. On real-game boards: beginners make simple swap mistakes and experts make formation mistakes --- suggesting that experts chunk and memorize on the level of formation, while beginners do so on the level of individual pieces. Note that when a random non-real-game position is given, both experts and beginners do equally poorly.

comment When is it best to use PsycINFO versus Google Scholar?
do we really need all these new tags? research-process, literature-review, publication-process, and university-training. I think this is far too many tags about doing research. There should be just one tag for that. Also, the lit-review tag is too easy to confuse with the much more established reference-request.

comment How do you refer to something in APA-style that is not submitted to be published?
@Jeff that would be a better fit that cogsci, in my opinion. But we should check with their mods.

comment How do you refer to something in APA-style that is not submitted to be published?
I don't think this question is on-topic. Although questions about the publication-process specific to cogsci/psych are on-topic, this is just a general and easy-to-search question about the APA style. We do not want to become a reference site for APA style. Also, I believe this does not meet standards of initial research

comment Spurious attractors in Hopfield networks
Thanks for asking this question! Minor comment: question 3 is a pretty big question on its own, and not as closely related to question 1 and 2. It might be worthwhile to ask it as a separate question, but it is up to you.

comment Are there any journal articles in psychology that have promoted and discussed reproducible data analysis?
It is PLoS (Public Library of Science) and it is not a journal, but it publishes several journals that have names that start with PLoS. None of these journals are psychology specific. Further, these journals don't "claim to be 'open-access'". They basically defined what it means to be open-access. However, I have not heard of them trying to promote reproducible data analysis, especially in psychology (they concentrate on bio and medicine mostly, although PLoS One does publish some other things); I don't see how your last paragraph has relevance.

comment Do high heels increase female attractiveness in men only through indirect means?
I imagine that standing on a slope would produce a different posture than standing in high heels (not to mention wanting photos mid-gait, etc). With what I was suggesting, you can just use the same photos and just crop out the part where the feet appear (or use photoshop magic to place some object to obscure the feet).

comment Do high heels increase female attractiveness in men only through indirect means?
Yes, I understood the question. If the foot is not visible, the posture still is. If you see the same amount of change from no-high-heel foot-not-visible to yes-high-heel foot-not-visibile as you see from no-high-heel foot-visible to yes-high-heel foot-visible then you can argue that the actual aesthetics of the shoe itself do not matter.
