Mar 11	comment	Hebbian Learning Rule, Local or Global? I don't particularly disagree with your comment, but I'm not sure of what your point is.
Mar 9	comment	How much information does the somatosensory system produce? I don't really know that bits is a sensible way to think about information processing in nervous systems. I'd need to he convinced
Mar 7	comment	Is fear rational? I'm not sure I agree that the emotion itself is rational. The action of running away from danger is rational, but the emotion is supplementary.
Mar 5	comment	What are the effects of social rejection on the brain? NeuroSynth (a meta analysis of fMRI results from several studies) tags several parts of the brain in association with the word "pain". I wonder which parts are activated in social rejection and what part they play in physical pain.
Mar 4	comment	What is the bias/thought process that results in distrust of “formal” knowledge in favor of “folk” knowledge? This sounds like assimilation vs accomodation
Feb 25	answered	Why are most people right handed?
Feb 19	awarded	Enthusiast
Feb 7	comment	How do humans perceive height or vertical drop? I'd speculate that this is the kind of higher order context processing that we know little about. I don't think we particularly process distance different, but that we know that gravity and distance together can hurt/kill us. We can predict the outcome and it scares us.
Feb 6	comment	What is the proper term for the synchronization of eye movements? Convergence refers specifically to eyes pointing more toward each other as objects enter nearfield, fusion is when each eye has its own image but a single image is perceived.
Feb 6	answered	What is the proper term for the synchronization of eye movements?
Feb 3	comment	Psychology of timbre processing Ah yeah, I agree. Too much emergent complexity involved with the second bullet point which means lots of degeneracy
Feb 3	comment	What are some examples of emergent abilities? I think this needs more initial research because it appears vague and speculative as it stands.
Feb 2	comment	Psychology of timbre processing For judgments, you could have one group rate some fixed set of qualities fir each timbre and have another group answer in their own words in a paragraph, then perform quantitative phenomenology analysis. The second group would help avoid a priming bias.
Feb 2	comment	Psychology of timbre processing I think you probably could to some extent. If you have people judge the quality of several timbres and see if there is a particular trend for timbres with sharper attacks for instance.
Feb 2	comment	Psychology of timbre processing I Mostly agree with Chuck. But I think the physics of the timbre are important to decomposing timbre so that we can talk about what different characteristics create what different effects. The major characteristics of timbre are: attack, decay, and sustain. They basically describe the shape of the envelope. Also important are the harmonics of the instrument (for instance, on a violin, the strings themselves have harmonics but the body of the violin also resonates). I think part of the richness of the violin as how intense the timbre is. The strings are constantly being perturbed.
Jan 31	comment	Are ambidextrous people better at multitasking? Looks like that idea has been challenged: www.sciencedirect.com/science/article/pii/S0028393208000675
Jan 31	comment	Are ambidextrous people better at multitasking? I actually remember reading about deficits in ambidextrous people. Try searching for that. If I have time and remember, ill look into it next time I'm at a computer.
Jan 30	comment	What is the fastest language to think in? speculation: chinese language uses tones (so the same word may have five different meanings depending on your tone). So if parallel processing tone and semantics doesn't cost any extra time, then I'd think that gives it a significant advantage in terms of efficiency.
Jan 28	comment	What part of the brain locks up when a man is in the presence of an extremely attractive female? Sure, just syntax difference (what locks up?)
Jan 28	comment	What part of the brain locks up when a man is in the presence of an extremely attractive female? I would argue that the amygdala is not what locks up, but that the amgydala becomes active and locks up other parts of the brain.
