Studying neuroscience at the Hebrew University.

My main interest is how the cognitive system combines prior knowledge about the world in the process of perception.

comment Sensitivity of human eye to luminance
No. decibels are indeed logarithmic, but note that the x-axis is "linear" in decibels, and the y-axis is logarithmic. So the relation between subjective estimate and luminance is linear in a log-log plot, i.e., a power-law.

comment Significant baseline, Oddball paradigm
a bandpass filter can be implemented as causal or non-causal ( en.wikipedia.org/wiki/Causal_filter ). a non-causal 0.5 to 20 Hz bandpass can cause what you are describing. I'll try to look for some references later.

2. What filters do you apply to the data before the ANOVA? Are you sure they are causal (i.e., the output of the filter in time t0 does not depend on the input in any time point t>t0)?

1. "I have observed a difference between standard stimuli's wave and deviant stimuli's wave" - You mean the EEG response in the time window before the stimulus?

comment Sensory dissonance: Will the visual or auditory channel win?
I agree this is no proof. I do think it is an example of visual dominance, because in the standard conditions our auditory perception is changed to match the visual cue, and not vice versa. (I'm also certain that under suitable conditions, like extremely degraded visual input, you can get it to work the other way around, and have the visual perception biased towards the auditory cue).

comment What are the “Must Know” papers of Cognitive Science?
@WhyDoYouThinkThatIsTrue the intent behind the original question was to find papers and works that I as a researcher in a specific subfield (perceptual learning, actually) should know outside of my specific topic of research, because they are so important, no one should call themselves a psychologist or a cognitive scientist without knowing them.

comment Is consistent dual n-back training likely to improve the performance of analysis (mathematics) students?
I don't think we need another answer saying the same thing. Feel free to add the refs to your answer. I would maybe only add that even the improvement of working memory capacity due to practice is doubted (and not just the transfer).

And another one: Melby-Lervag, M., & Hulme, C. (2012). Is working memory training in children effective? A meta-analytic review. Developmental Psychology.

Another, more recent review, claiming that we currently have no good evidence of working memory improvement due to practice, and certainly not of transfer to other areas: Shipstead, Zach; Redick, Thomas S.; Engle, Randall W. Psychological Bulletin, Vol 138(4), Jul 2012, 628-654. doi: 10.1037/a0027473

comment Does reading a book out loud make you better in social situations?
I agree, but would like to add that if you're trying to improve your aptitude in social situations in a language that is not your native, then reading books in that language (aloud or not) is a very effective way.

comment Have humans always had problems with motivation and laziness?
Perhaps counter-intuitively, "hard working" is very rare, relative to the other words I used, according to the Ngram data. Maybe it has to do with it being a two-word phrase, as opposed to the others that are one word phrases.

comment Have humans always had problems with motivation and laziness?
@Gaël Laurans, that's why I called it 'Toy example'. Its an example of how one can use such data to address this question, and not an actual study.

comment How to use Mechanical Turk for longer studies (i.e., 30 minutes+)?
What is the main motivation for using mturk (or generally, online workforce)? Is it because you need more participants than you can recruit using conventional methods? Because you want a long study that won't require your participants to come to the lab every day? Some other reason?

comment Do people estimate combined probabilities differently to uncombined ones?
Welcome to CogSci. This sounds like an interesting question, but after the example in the last paragraph, I'm not sure I understand what you mean by cumulative and non cumulative. The term cumulative as I know it refers to questions like "what is the probability of at least 4 heads in tosses", while non cumulative would be "what is the probability of exactly 4 heads in 6 tosses". Is that what you mean? If not, can you be more specific and define what you mean by the term?

comment Math or Physics: Which is the more relevant background to enter Cognitive Sciences and Psychology?
+1. In physics, most experiments are so reliably reproducible, that you rarely encounter the need for solid knowledge of statistics. At least for me, this was a weak point for some time after moving to cognitive science...

comment Is there a variance in acceptance of conspiracy theories by occupation?
The article you link to is actually a book review about this book: amazon.com/… . From the review it sounds like an interesting book, but doesn't answer your question.

comment Why is training better when following an easy-to-difficult schedule?
The thing that makes most gradient descent algorithms learn faster at the beginning is simply the larger learning rate parameter, forced onto the algorithm, and not the difficulty of examples.

comment Analysis of parameter estimates from Ratcliff diffusion model
Is there anything specific to Ratcliff's model here? Because the way I see it, this question is equally valid to any model you fit to any multi-subject data.

comment Analysis of parameter estimates from Ratcliff diffusion model
"My understanding was that it is not a valid approach to put together estimates from models with different parameters" - Where did you understand that from?
