After distinguishing reductive explanability in principle from ontological deflation, I give a case of an obviously physical property that is reductively inexplicable in principle. I argue that biological systems often have this character, and that, if we make certain assumptions about the cohesion and dynamics of the mind and its physical substrate, then it is emergent according to Broad's criteria.

A proximal mechanism is proposed whereby early crying helps maintain ideal levels of brain activation during the first three postnatal months. The proposal is consonant with both animal and human infant literatures, and new data are presented in its support.

Atran & Norenzayan's (A&N's) target article effectively combines the insights of evolutionary biology and interdisciplinary cognitive science, neither of which alone yields sufficient explanatory power to help us fully understand the complexities of supernatural belief. Although the authors' ideas echo those of other researchers, they are perhaps the most squarely grounded in neo-Darwinian terms to date. Nevertheless, A&N overlook the possibility that the tendency to infer supernatural agents' communicative intent behind natural events served an ancestrally adaptive function.

Pickering & Garrod's (P&G's) call to study language processing in dialogue context is an appealing one. Their interactive alignment model is ambitious, aiming to explain the converging behavior of dialogue partners via both intra- and interpersonal priming. However, they ignore the flexible, partner-specific processing demonstrated by some recent dialogue studies. We discuss implications of these data.

This commentary argues that Ross & Spurrett (R&S) have not shown that supervenience is two-way, but they have shown that all the sciences, including physics, make use of functional and supervenient properties. The entrenched defender of Kim's position could insist that only fundamental physics describes causal relations directly, but Kim's microphysical reductionism becomes completely implausible when we consider contemporary physics.

We agree with Pickering & Garrod's (P&G's) proposal that dialogue is an important empirical and theoretical test bed for models of language processing. However, we offer two cautionary notes. First, the enterprise will require explicit computational models. Second, such models will need to incorporate both joint and separate speaker and hearer commitments in ways that go beyond priming and alignment.

Krueger & Funder (K&F) see social psychologists as driven to demonstrate that people's behavior falls below relevant moral and intellectual standards. We suggest that social psychologists search for demonstrations of when it is that people's actual behaviors and decisions deviate from expected or ideal behaviors and decisions, and what these “deviations” tell us about general decision processes, including those that do not produce unexpected actions. Often the discoveries are of positive rather than negative behaviors.

From a religious studies perspective, Atran & Norenzayan (A&N) succeed in arguing for the influence of evolved cognitive functions in religious phenomena. To develop their argument further, four suggestions are offered: (1) Look beyond the ordinary to the extraordinary; (2) culture matters more than ever; (3) theists need not despair, atheists ought not celebrate; and (4) dreaming is a primal wellspring of religion.

This commentary focuses on issues related to Glover's suppositions regarding the information available to the on-line control system and the behavioral consequences of (visual) information disruption. According to the author, a “highly accurate,” yet temporally unstable, visual representation of peripersonal space is available for real-time trajectory corrections. However, no direct evidence is currently available to support the position.

Unlike chimpanzees, human infants engage in persistent adult-directed (AD) crying, and human mothers produce a special form of infant-directed vocalization, known as motherese. These complementary behaviors are hypothesized to have evolved initially in our hominin ancestors in conjunction with the evolution of bipedalism, and to represent prelinguistic substrates that paved the way for the eventual emergence of protolanguage.

Krueger & Funder (K&F) could have gone further to sketch out a more comprehensive vision of “balanced” psychology. The triumphs and travails of other sciences (e.g., economics) provide clues about the advantages and pitfalls of pursuing such an approach. Perhaps introducing more positivity into psychology may involve asking how people can do better, not how well they do already.

The perception/planning–control conception has a direct predecessor in a cognitive/sensorimotor scheme, where the cognitive branch includes Glover's perception and planning functions. The sensorimotor branch corresponds to Glover's control function. The cognitive/sensorimotor scheme, like the perception/planning–control scheme, differentiates between motor planning and direct motor control, which is inaccessible to awareness or to long-term memory.

Ross & Spurrett (R&S) argue that Kim's reductionism rests on a restricted account of supervenience and a misunderstanding about causality. I contend that broadening supervenience does nothing to avoid Kim's argument and that it is difficult to see how employing different notions of causality helps to avoid the problem. I end by sketching a different solution.

Pickering & Garrod (P&G) argue that contemporary models of language use are inadequate. This has resulted largely because of an experimental focus on monologue rather than dialogue. I agree with the need for increased experimentation that focuses on the interplay between production and comprehension. However, I have some concerns about the Interactive Alignment model that the authors propose.

Atran & Norenzayan (A&N) correctly claim that religion reduces emotions related to existential concerns. Our response adds to their argument by focusing on religious differences in the importance of emotion, and on other emotions that may be involved in religion. We believe that the important differences among religions make it difficult to have one theory to account for all religions.

By synthesizing evolutionary, attachment, and acoustic perspectives, Soltis has provided an innovative model of infant cry acoustics and parental responsiveness. We question some of his hypotheses, however, because of the limited extant data on infant crying among hunter-gatherers. We also question Soltis' distinction between manipulative and honest signaling based upon recent contributions from attachment theory.

We argue that one can explain why the influence of illusions decreases during a movement without assuming that different visual representations are used for planning and control. The basis for this is that movements are guided by a combination of correctly perceived information about certain attributes (such as a target's position) and illusory information about other attributes (such as the direction of motion). We explain how this can automatically lead to a decreasing effect of illusions when hitting discs that move in an illusory direction, and when grasping objects of which the apparent size or orientation has been changed by an illusion.

A balanced approach that considers human strengths and weaknesses will lead to a more flattering set of empirical findings, but will distract researchers from focusing on the mental processes that produce such findings and will diminish the practical implications of their work. Psychologists ought to be doing research that is theoretically informative and practically relevant, exactly as they are doing.

According to embodied cognition theory, our physical embodiment influences how we conceptualize entities, whether natural or supernatural. In serving central explanatory roles, supernatural entities (e.g., God) are represented implicitly as having unordinary properties that nevertheless do not violate our sensorimotor interactions with the physical world. We conjecture that other supernatural entities are similarly represented in explanatory contexts.

An evolutionary account of excessive crying in young infants – colic – has been elusive. A study of mothers with new infants suggests that more crying is associated with more negative emotions towards the infant, and perceptions of poorer infant health. These results undermine the hypothesis that excessive crying is an honest signal of vigor.
