An experimental study found evidence of benefits and costs to peer-interaction during a paired-associates task, acting through both a knowledge and a motivation channel. Computational cognitive modeling was used to identify both a knowledge spillover and a trust mechanism involved in learner interaction.

We argue for the explanatory power of the Parallel Architecture (PA) in the domain of language. The PA permits the precise description of every aspect of linguistic phenomena, from the very general to the very idiosyncratic; it is minimalist, in that it requires linguistic generalizations to be expressed in terms of syntactic, semantic, phonological and discourse representations; it allows for linguistic phenomena to be properly linked to non-linguistic cognition; and it illuminates which parts of language are universal, which are subject to variation, and the dimensions and sources of variation.

This global cross-cultural review uses the HRAF ethnographic database to analyze human–fungi interactions worldwide. It describes mushroom use in contexts including rituals, food, medicine, folklore, foraging practices, and cognition.

Humans understand time in a way no other animal does. This is not because of our evolved biology, however—it is because we have developed a diverse and powerful toolkit of ideas, practices, and artifacts over cultural evolution. These time tools allow us to tally, coordinate, predict, measure, record, remember, and reason, and, ultimately, have transformed our very understanding of what time is.

We examine the use of cognitive technologies in botanical knowledge for medicinal purposes in the Nahua (Aztec) Cruz-Badianus codex. The Mesoamerican cosmovision, especially the association of human body and cosmos, is reflected in the text.
