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.

OP, I think you should familiarize yourself with the basics of NLP. For some introductory resources, see this question and answers on ling.SE

comment Bias towards purchasing tangible vs virtual goods
@BenBrocka The new title makes me think of a different question that the original formulation. In the original formulation I thought of going to a book store versus buying a book on Amazon except for cheaper items. The current version of the question seems to be about buying goods that are not physical (not just purchasing physical good via the online medium). Is that the intended question by the OP? In either version, I agree that OP should wait to ask question 3 after receiving answers to 1 and 2.

comment Using natural language processing for traffic monitoring from video
I can't understand what you are asking. Also, if you don't what "stuff" you are doing, how can you ask for open-source tools for doing it? Figure out what you want to do and how to phrase it precisely and accurately in the form of one question, then based on what you learn in your initial search ask a specific well-focused questions. At this point I have to vote to close as "not a real question".

comment Is this optical illusion the visual equivalent of binaural beats?
@draks try to be more precise when you mean 'brain' and when you mean 'mind', and definitely try to be more precise with the word 'stimulate'; Any stimuli trivially stimulates. Also, drastically changing the question (by for instance changing the image it is based around) after it has answers is usually considered bad form.

Welcome to the site! Glad to have you, here. I have formatted your question slightly for readability (and added two tags), feel free to roll-back my edits if they do not preserve the spirit of your question.

comment Subconscious vs Unconscious
@cpx the whole point of the vagueness of 'subconscious' in everyday use is that it is not clear what people mean when they say it. Sometimes they mean 'preconscious' and sometimes they mean 'unconscious' (and sometimes they mean something else completely). They way you used 'subconscious' in your question (and as I already explained in my answer) is more-or-less the same as the technical term 'preconscious'.

comment What are current neuronal explanations and models of 'consciousness'?
I think the scholarpedia article on models of consciousness is a very good source for this question.

This is an awesome answer! I added some formatting and links to make it a bit quicker to read. If that is an issue, feel free to roll-back my edits.

comment Visual search: complexity of positive vs negative search tasks
The only 'self-theorizing' is that "not" is not an essential property. But if you think the answer is incorrect, or does not answer the question, then I welcome the downvote. I personally think @H.Muster gave a better answer to this question, and I am not 100% sure why OP accepted my answer, apart from maybe the reference to Treisman that completely answers his specific question.

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.

@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 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.
