We ask whether experiences of parents can affect future children and describe a study that suggests the answer is yes. A second study, described in the same reference, shows similar effects. Young female mice were assigned to either live for two weeks in an enriched environment or not. Matching what has been seen in other similar experiments, the adult mice who had been exposed to an enriched environment were smarter (in the sense that they learned how to navigate mazes faster) than the mice that did not have that experience. The other interesting result, however, was that the offspring of the mice exposed to the enriched environment were also smarter than the offspring of the other mice, even though none of the offspring were exposed to an enriched environment themselves. One variable is whether or not the young female mice lived in an enriched environment and another variable is how fast the offspring learned to navigate mazes. Is the variable whether the female mice lived in an enriched environment categorical or quantitative? Is the variable how fast the offspring learned to navigate mazes categorical or quantitative? Is the variable how fast the offspring learned to navigate mazes the explanatory variable or the response variable?

Trans-Generational Effects of Environment

We ask whether experiences of parents can affect future children and describe a study that suggests the answer is yes. A second study, described in the same reference, shows similar effects. Young female mice were assigned to either live for two weeks in an enriched environment or not. Matching what has been seen in other similar experiments, the adult mice who had been exposed to an enriched environment were smarter (in the sense that they learned how to navigate mazes faster) than the mice that did not have that experience. The other interesting result, however, was that the offspring of the mice exposed to the enriched environment were also smarter than the offspring of the other mice, even though none of the offspring were exposed to an enriched environment themselves. One variable is whether or not the young female mice lived in an enriched environment and another variable is how fast the offspring learned to navigate mazes.

Is the variable whether the female mice lived in an enriched environment categorical or quantitative?

Is the variable how fast the offspring learned to navigate mazes categorical or quantitative?

Is the variable how fast the offspring learned to navigate mazes the explanatory variable or the response variable?
