Rakison and Yermolayeva (this issue) argue that domain specificity is difficult to reconcile with U-, N-, or M-shaped developmental trends. They are justified because: 1) There is no compelling evidence that nonlinear trends require mechanisms beyond general, well-known cognitive processes; and 2) epigenetic neuroscience provides no clear evidence of strong domain-specialized representations. Evidence implies pervasive weak (i.e., experience dependent) neural specialization for different kinds of information. © 2011 Taylor & Francis Group, LLC.
