2. Recent studies have allowed psychologists to establish
definite links between specific foods and specific brain
functions. For example, lecithin has been shown to increase
the concentration of certain brain chemicals that help
regulate memory and motor coordination.
An experiment was conducted that involves two separate
samples of newborn rats. The ten rats in the first sample
are given a diet with standard amounts of lecithin. The five
rats in the second sample are fed a special diet, which
contains almost no lecithin. After 6 months, each rat is
tested on a specially designed learning problem that
requires both memory and motor coordination. The score
for each animal is the number of errors it made before
solving the learning problem.
