People want to form impressions of others based on their moral behaviours, but the most diagnostic behaviours are rarely seen. Therefore, societies develop symbolic forms of moral behaviour such as conventional rituals and games, which are used to predict how others are likely to act in more serious moral situations. This framework helps explain why everyday behaviours are often moralized.

Although it makes some progress, McKay & Dennett's (M&D's) proposal is limited because (1) the argument for adaptive misbelief is not new, (2) arguments overextend the evidence provided, and (3) the alleged sufficient conditions are not as prohibitive as suggested. We offer alternative perspectives and evidence, including individual differences research, indicating that adaptive misbeliefs are likely much more widespread than implied.

Evidence is presented for the notion that selection-for-perception and selection-for-action progress in parallel to become tightly coupled at the saccade target before the execution of the movement. Such a conception might be incorporated in the E-Z Reader model of eye-movement control in reading.

Thelen et al. not only offer an important new theoretical account of the Stage 4 object permanence error but provide the foundation of a new theory of cognitive development that is grounded in action. The success of dynamic field theory as a more general account of cognitive functioning, however, will depend on the degree to which it can model more generative capacities that are not limited to simple choice situations. Imitation and problem solving are suggested as two capacities that might be productively modeled within their approach.

Severity of Test (SoT) is an alternative to Popper's logical falsification that solves a number of problems of the logical view. It was presented by Popper himself in 1963. SoT is a less sophisticated probabilistic model of hypothesis testing than Oaksford & Chater's (O&C's) information gain model, but it has a number of striking similarities. Moreover, it captures the intuition of everyday hypothesis testing.

The evidence Atran uses to support innate biological principles could just as well support learning, just as in another realm often cited as a candidate for innate knowledge, “naive psychology.”

Behaviorists accept, but go beyond, Williams' notion that there is an evolutionary origin to some unlearned pain behaviors. A behavior-analytic developmental model is a better fit for explaining the totality of pain behaviors. This model focuses on respondent-operant interactions and views much pain behavior as “mands” (i.e., demands). Behaviorally based explanations from the crying and social referencing literature support this model.

Alternative interpretations are proposed for the finding that market integration is positively related to fair behavior in experimental games. Market activities may produce market relevant concepts and stories that interpret experimental games as incidences of social exchange, and thus may enhance the relevance of (1) market-related preferences or (2) a decision heuristic designed for social exchange.

Authors of non-liberal proposals experience more collegial objections than others do. These objections are often couched as criticism of determinism, reductionism, or methodological individualism, but from a scientific viewpoint such criticism could be easily answered. Underneath it is a wish to harness scientific belief in service of positive social values, at the cost of reducing objectivity.

Palmer demarcates the bounds of our understanding of color experience by symmetries in the color space. He claims that if there are symmetries, there can be functionally undetectable color transformations. However, even if there are symmetries, Palmer's support for the possibility of undetectable transformations assumes phenomenal internalism. Alternatively, phenomenal externalism eliminates Palmer's limit on our understanding of color experience.

The convincing argument that Brette makes for the neural coding metaphor as imposing one view of brain behavior can be further explained through discourse analysis. Instead of a unified view, we argue, the coding metaphor's plasticity, versatility, and robustness throughout time explain its success and conventionalization to the point that its rhetoric became overlooked.

There is a spectrum of child psychiatric and neurological disorders, in all of which a comorbidity with obsessive-compulsive disorder and ritualized behavior is very common. Therefore, they may appear as a basis for the rituals in children that cross into adolescence and adulthood. Resolving the nature of these disorders may help us to better understand Why ritualized behavior?
