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 Neural networks with biologically plausible accounts of neurogenesis
@MattMunson thanks for your answer. I was actually organizing an online reading group on neurogenesis with some colleagues so that we could start seriously thinking about some of these questions. Unfortunately everything got delayed because there were a few other projects ahead in the queue. If you are interested in the reading group then send me an email.

@ChrisS unfortunately this not on-topic on cstheory, and I would not want to ask it there. Thanks for catching the dead link!

An earlier question on the connection between cognitive-psychology and the SPE might be of interest.

comment Is there a random walk theory that can account for situations with more than two choices?
Good reference, could you expand your answer a little bit on the core ideas of their model?

comment Behaviorist interpretations of decision field theory
Yeah, I suspect this much as well. The other important factor being that behaviorism is simply not as fashionable among psychologists anymore.

comment Are there known cases where people can write upside down?
I agree with @nico that this question is off-topic or not a real question. It is way too much about personal experience, and does not show any initial research effort, not even the basic searching on CogSci.SE to find the related question Josh Gitlin linked.

I would comment on the original question, unless you have enough of a follow up question to make a separate one. I know that the OP wanted to ask another question about the reliability of timing data, and the second part of your answer would be great for that; but she has yet to ask the follow up.

this isn't an answer, but it is a very interesting question/comment. I would encourage you to ask this as a separate question since answers are not supposed to be used for further questions or discussion.

comment What explains variability in the mean firing rate across biological neurons?
I think you are missing the point of the question with (1) and (2). Regardless if it is the presence of a signal or the absence that triggers something, if you speed up everything by a factor of 10, your whole information processing will speed up by a factor of 10 (as a crude analogy, think refresh rate on processors). However, your energy consumption will also increase (crude analogy: heat loss in processors).

comment What explains variability in the mean firing rate across biological neurons?
Just a quick question. Why do you expect one solution? Couldn't the optimum vary from brain region to brain region and in general depend in a complicated way on the topology?

comment Is there a reduction of “Brain Fog” with fewer hours of sleep?
I think there are two essential sub-questions you could ask separately to help you answer this question. (1) a terminology question about the proper term for "Brain Fog" as you describe it, and (2) if there are good theories explaining the effects of sleep deprivation on depression. The answers to those two questions might help you answer this one.

@BenBrocka why would JS be more reliable than flash?

comment Method for evaluating how emotionally evocative a question is?
Is it just to hearing the statement of the question that you are interested in? If so, what is it in particular about questions that matters, why not not reaction to a general statement (be it question or not)? If you are interested in making the measurements when people are responding to a question, then I am sure there is a huge literature on it related to the polygraph and other techniques. Where have you looked already?

Okay, after you ask the new question, you can click the 'edit' button below this question to remove the last paragraph and incorporate the content of your comment (i.e. that you want timing data and that the answers in the other question demand plug-ins). Also, take a look at this answer, it seems to come pretty close, but technically does require the flash plug-in, but most browsers have that by default. Hopefully @AndyDeSoto will notice this question and give more insights.

comment What is the term for “What has been seen cannot be unseen” in cognitive sciences?
can you expand a little bit on your answer to give a quick sketch of what visual one-shot learning is and why its relevant?

comment Software for online psychological experiments that don't require users to download anything
Welcome to cogsci.SE! Can you expand a little bit in your question on why the answers on the earlier question don't fulfill your needs? It is not clear to me from the question, but do you still want to collect timing data? Also, I feel like the last paragraph is distinct enough from the ones above it to merit a separate question.

comment Biological plausibility of bayesian models of cognition
I am sure that our stances are not nearly as far apart as we might think, and I will love to argue with you some more later. Unfortunately, I have a bus to catch. Cheers to tomorrow!

comment Biological plausibility of bayesian models of cognition
As for the distinction between model and empircal. The point is that there are MANY choices of models: your pet model leads to Bayesian fixed-points, my pet model does not. Which model better describes reality is not up to us, but up to the biologists. Hence an argument of the form "bayesian reasoning is a fixed point of my pet model of evolution" carries no weight for the biological plausibility of bayesianism, unless you can defend the biological plausibility of your pet model. Something you have not done.

comment Biological plausibility of bayesian models of cognition
That is exactly the point of my argument. When you say something as vague and meaningless as "dominate" you leave it free for me to interpret what that means. A natural metric from an evolutionary point of view, is biomass; the things that dominate in biomass seem to be doing almost no bayesian computation at all, so an argument of "bayesian computation is important to 'dominate'" becomes a little silly.
