College students were tested in general factors like learning preference and spatial ability (being able to be proficient in creating, holding, and manipulating spatial representations).

First, those with the more trained spatial ability tend to take part in experiences that require those skills.

Now, in the century of the brain, neuroscientists are able to describe in great detail the sensory receptors and brain processes that enable our spatial abilities.

Second, the experience trained the person to develop spatial abilities.

Alcohol's negative effects on learning, spatial abilities and memory has been shown in many studies.
