K. J. Gergen's (1982) argument that hypotheses in social psychology are not empirical propositions is critically examined and shown to be erroneous. Nevertheless, this article demonstrates that, without necessarily appearing obvious, some hypotheses can be derived from propositions that are like tautologies and that their confirmation as such is of little interest. An analysis of hypotheses in ...

In our simulations with simple recurrent networks we demonstrate that small artificial languages are learnt differently depending on their basic word order. We show that verb-initial languages are difficult to learn, reflecting the lower frequency of verbinitial natural languages. We try to go beyond mere simulations proposing two objective mathematical measures to explain our results.

Fortification of foods such as salt has been shown to be an effective way to ensure pregnant women get adequate iodine, a critical nutrient for proper brain growth. But dietary and food production shifts in the past few decades have resulted in dramatically decreased population levels of iodine, with potentially devastating effects for babies of iodine-deficient mothers.

T relationship of body size to the anatomical, physiological, behavioral, and ecological characteristics of animals has long been a focus of interest in zoology. As one considers animal species of different sizes, regular, predictable changes are seen in the relative proportions of the body’s organs and the relative rates of physiological processes such as metabolism and growth. Students of zoo...

We examined the cardiovascular physiology of guilt and pride to elucidate physiological substrates underpinning the behavioral motivations of these moral emotions. Although both emotions motivate prosocial behavior, guilt typically inhibits ongoing behavior, whereas pride reinforces current behavior. To succeed in eliciting real emotions, we used a novel social interaction task. We found dissoc...
