HOUSE OVERSIGHT 025961 no worry, if i understand correctly you are suggsting there are layers 1 through N. lets cal them L 1 - Ln. there are times T 1- Tn / and then conjecture that changing the time . correlations ( by genetic swtch or other method. , you might be able to make blacks smarter by changing the time for motor layer development and changing the time for other layers. . ). like telemeres for the cell , are their equivalents for the layers. . as you talked about culling the unused neurons in each layer, each neuron in each layer would get dfferent ( kill yourself if you are not being used instructions ). Exactly. I looked up the statistics, black kids in the US have slower cognitive development (and never catch up), which the study of course attributed to social factors without any evidence, and they had faster motor development! I suspect this means their brains are slower at learning high-level concepts, because the low- level structures are optimized for a shorter time. But they will keep the lead in motor development, because it is easier to learn, and they have more time and attention to practice once they get the structures in place. It could also be that they have an additional set of learning directives in place that adapts them better to a more hunting/running style of life, whereas the Europeans had to adapt for identifying long-term seasonal patterns, delayed gratification for agriculture etc. and CONCEPTS could be layer to layer communicaiton. . are gender differences also a matter of time, and structure of interactions. . I suspect gender differences are mostly motivational, i.e. we have a reward system for all the different social and cognitive needs, which makes us receive different kinds of pleasure and pain, thereby pay attention and learn. You cannot learn what does not attract your attention. Women tend to find abstract systems, conflicts and mechanisms intrinsically boring. Most women in computer science do not write
