infection
"An infection is like a fire," Dr Davies says. "It can smoulder. It can go out or become an inferno."
A portion of the abstract:
"This paper reports an experiment that investigated whether children can profit from the use of explanatory analogies to acquire information from expository text. Five-year old (N=24) and 7-year old (N=34) children listened to four texts describing relatively unfamiliar topics with or without explanatory analogies."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
