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.

Aug 16	comment	Is the Myer Briggs Type indicator (MBTI) a reasonable scientific theory? For a recent follow up on popularity and comparison to other personality theories, there is this new question.
Aug 15	comment	What is the effect of motherese on development? Thanks, this explains the phonetic and high-pitched/weirdly-articulated nature of motherese. It doesn't capture why they would use simplified grammar, etc... maybe someone else will pitch in on if those have well understood developmental roles.
Aug 14	comment	What is the mechanism explaining the effect of a positive attitude on immune system functioning? I am a little bit skeptical of this answer. Writing off the placebo effect as something insignificant is not appropriate in all cases, I would appreciate it if you expanded on your reasoning behind this and/or provided some references. I understand it is really hard to find references for negative claims, but somehow this seems to be too simple of an explanation to be true.
Aug 13	comment	What is the mechanism explaining the effect of a positive attitude on immune system functioning? when looking for possible connections, it is best not to make implicit assumptions. This question will be greatly improved if you do the initial research and include an example reference (like this but one you have taken time to look over) to frame your question. Also, as written it is not clear if you are asking for the specific mechanism (and at what level of description) or if you are just looking for general data on relationship between place-effect and recovery time.
Aug 11	comment	Details About How Information Is Stored in the Neural Structure? I agree with @Preece that the question could be salvaged if the OP focuses it slightly and included proper references. Remember, you can edit questions and ask for them to be re-opened.
Aug 10	comment	Does writing something down help memorize it? This is a nice, but it would be great if you could throw in some references. Also, welcome!
Aug 9	comment	Is the Neanderthal Theory of Autistic brain a reasonable scientific theory? An anthropology blog post that might be of interest.
Aug 9	comment	Is human Central Nervous System arousal related to choice of activity? You defined "CNS activity" as "gross motor activity measured by an actigraph". Doesn't this trivially correlate to people choice of activity? If I am choosing to jog, my actigraph will read higher. Are you normalizing in some way? Or are you trying to predict the future hour given on the past hour? What kind of non-trivial answer are you expecting? What is the point of the diagram? Also, I think your definition of 'CNS arousal' is non-standard and controversial. If I was you I would replace all occurrences of it and replace them by your actual actigraph-based definition.
Aug 9	comment	What is a source of case studies of personality disorders? I removed my downvote on the question, the present form shows a good initial research effort of liz's part. I made some minor edits to tags and the text, let me know if I lost the spirit of the question (I added an open-access clause, since OP seems to be looking for free resources).
Aug 8	comment	Technical model of how babies and young children learn suited to a parent with an engineering background? On my reading the question is either too broad or a duplicate of Computational models of early learning in children or Introductory resources on developmental psychology/neuroscience. I recommend that you focus the question to your needs, something like a technical accounts for parenting a child with Downs Syndrome.
Aug 7	comment	How many times can someone listen to a song before he/she stops enjoying it? I don't think this question is particularly well framed. As the OP noticed and @GaneshKarapakula commented, there is a built in assumption in this question that is not supported by any initial research on the part of the OP. I have voted to close this as NaRQ. However, I encourage the OP to revise the question into something that assumes less or is framed by existing research.
Aug 4	comment	Judgments of similarity between samples of writing Welcome to the site. I think the OP is more interested in studies of people's judgements of similarity, not so much the software implementations of style identification (he seems to only mention them in reference to forming a base-line). Can you edit your answer to address the human judgement portion more clearly?
Aug 4	comment	Do the students that report “friendly” teachers perform better on standardized tests? This would require very delicate controls to disentangle a 'friendly' ranking from a 'good' or 'easy-grader' ranking. Anecdotally, educational psych is bad at doing such carful controls.
Aug 2	comment	Is there evidence that brain and mind are separate? @Xurtio I want to upvote this answer, but I can't because of your nonchalant dismissal of philosophy as pseudoscience. There is a huge difference between pseudoscience (which tries to make scientifically testable and usually false in the most silly ways claims, and ground itself in science) and well practiced philosophy which tries to provide a completely different type or argument and is usually painfully clear about when it is making scientifically testable claims, ad when it makes non-testable one. Further, you can't "prove" anything in science... this isn't math.
Aug 2	comment	Is there evidence that brain and mind are separate? this is a great answer. Sometimes people take reductionism too far and too seriously.
Aug 2	comment	Is there evidence that brain and mind are separate? @degausser I don't think you have an understanding of how vast the scientific literature is, scientists already spend most of their days reading, and still have no chance to cover anything but a fraction of their very specialized sub-sub-sub-field. The wikipedia article already goes to decent lengths to answer your question.
Jul 26	comment	Does each sensory neuron type have a characteristic spike sequence pattern? there are plenty of NN where the wiring is not specified initially. Why don't you look up the cascade correlation algorithm or some of the questions I asked. Making significant edits to a question after it has been answered is considered poor form.
Jul 26	comment	Does each sensory neuron type have a characteristic spike sequence pattern? to your final question. Did you spend time thinking about my comment. The key part of neural-networks is their wiring pattern, I recommend reading a bit of wikipedia before follow up questions, though.
Jul 26	comment	What was his name again…ahh got it! This is also almost the same as this question
Jul 23	comment	Need good example of two domains involving different procedural knowledge yet sharing same high-level strategies What is wrong with the following 2 or 3 domains: addition, multiplication, and (maybe) matrix multiplication? For the first two you can exploit both associative and commutative laws, for the second you only have the associative law to help you. For all 3 domains you have a heuristic notion of size you can use to guide which terms to combine first, etc. Further, picking the optimal order in which to multiple matrices (of varying but compatible dimensions) is a well studied problem in computer science, with known hardness results.
