The pattern of data underlying the successful replications of cleansing effects is improbable and most consistent with selective reporting. Moreover, the meta-analytic approach presented by Lee and Schwarz is likely to find an effect even if none existed. Absent more robust evidence, there is no need to develop a theoretical account of grounded procedures. [ABSTRACT FROM AUTHOR]

We propose that Vaesen's target article (a) underestimates the role of language in humans' cognitive toolkit and thereby (b) overestimates the proposed cognitive discontinuity between chimps and humans. We provide examples of labeling, numerical computation, executive control, and the relation between language and body, concluding that language plays a crucial role in “supersizing humans' cognitive toolkit.” [ABSTRACT FROM PUBLISHER]

This commentary seeks to clarify the potential discrepancy between lab-based and field data in the use and effectiveness of punishment to promote cooperation by recommending theory that outlines key differences between the lab and field, such as the shadow of the future and degree of information availability. We also discuss a recent meta-analysis (Balliet et al. 2011) that does not support all conclusions outlined in Guala's target article. [ABSTRACT FROM PUBLISHER]
