In this commentary, I agree with Chow's treatment of null hypothesis significance testing as a noninferential procedure. However, I dispute his reconstruction of the logic of theory corroboration. I also challenge recent criticisms of NHSTP based on power analysis and meta-analysis.

An adaptationist analysis of beliefs yields the prediction that we ought to expect accuracy in the cognitive systems which generate them – stereotypes or otherwise – for the most part. There are, however, some limited situations in which some inaccuracy in beliefs advertised to others might be adaptive.

We argue, by analogy to the neural organization of the object recognition system, that demonstration of modulation of mirror neurons by associative learning does not imply absence of genetic adaptation. Innate connectivity defines the types of processes mirror neurons can participate in while allowing for extensive local plasticity. However, the proper function of these neurons remains to be worked out.

On the basis of neuropsychological evidence, it is clear that attention should be given a role in any model (or conjecture) of consciousness. What is known about the many instances of dissociation between explicit and implicit knowledge after brain damage suggests that conscious experience might not be linked to a restricted area of the brain. Even if it were true that there is a single brain area devoted to consciousness, the subicular area would seem to be an unlikely possibility.

Explaining the transition from nonhuman to human behavior is a major scientific problem. Penn et al. argue for discontinuous evolution; they review many relevant papers but miss some that disagree with their stance. Given the shifting ground on which Penn et al.'s theories are based, and the likelihood of future studies providing additional information on continuities, a more open approach to continuity is warranted.

We propose an extension to the map of Bentley et al. by incorporating an aspect of underlying network structure that is likely relevant for many modes of collective behavior. This dimension, which captures a feature of network community structure, is known both from theory and from experiments to be relevant for decision-making processes.

In evaluating the insurance hypothesis as an explanation for obesity, we propose one missing piece of the puzzle. Our suggested explanation for why individuals report food insecurity is that an individual may have an impaired episodic ability to plan for the future.
