In this issue of Neuron, Nandy et al. (2017) reveal a number of important new insights into the neural mechanisms that are responsible for attentional selection.

Traditional theories of attention rely on the idea that when we search for a target in a visual display the brain boosts the activity of neurons optimally tuned for the target features. In this issue of Neuron, Navalpakkam and Itti take a computational approach to show that this strategy is actually very inefficient when the target is surrounded by distractors with similar features. Instead, th...

Currently available empirical evidence is often insufficient to distinguish among developmental theories of word learning, categorization, and induction. This paper argues that theories of conceptual development should be evaluated not only on the basis of their ability to account for empirical findings, but also on the basis of their consistency with a broader body of knowledge, particularly w...
