What Conclusion was Based on Experiments with "Maze-Bright" and "Maze-Dull

Question

What conclusion was based on experiments with "maze-bright" and "maze-dull" rats?
A) An enriched environment increases maze-running ability only in dull rats.
B) A poor environment adversely affects maze-running ability in both bright and dull rats.
C) Maze-running ability is highly heritable and unaffected by environment.
D) Maze-running ability is based entirely on environment and unaffected by genes.

Accepted Answer

The conclusion based on experiments with "maze-bright" and "maze-dull" rats is that a poor environment adversely affects maze-running ability in both bright and dull rats. The experiment showed that rats raised in an enriched environment, regardless of their initial classification as bright or dull, performed better in maze-running tasks than those raised in a poor environment. This suggests that environmental factors play an important role in shaping cognitive abilities, and that a lack of stimulation can have negative effects on learning and memory.
