ded with tempting apples. You hesitate, then climb the
fence, pick an apple and eat it, hearing the owner's dog bark as you
leave the place. The accompanying diagram will illustrate roughly the
centers of the cortex which were involved in the act, and the
association fibers which connect them. (See Fig. 18.) Now let us see
how you may afterward remember the circumstance through association. Let
us suppose that a week later you are seated at your dining table, and
that you begin to eat an apple whose flavor reminds you of the one which
you plucked from the tree. From this start how may the entire
circumstance be recalled? Remember that the cortical centers connected
with the sight of the apple tree, with our thoughts about it, with our
movements in getting the apple, and with hearing the dog bark, were all
active together with the taste center, and hence tend to be thrown into
activity again from its activity. It is easy to see that we may (1) get
a visual image of the apple tree and its fruit from a current over the
gustatory-visual association fibers; (2) the thoughts, emotions, or
deliberations which we had on the former occasion may again recur to us
from a current over the gustatory-thought neurones; (3) we may get an
image of our movements in climbing the fence and picking the apple from
a current over the gustatory-motor fibers; or (4) we may get an auditory
image of the barking of the dog from a current over the
gustatory-auditory fibers. Indeed, we are _sure_ to get some one or more
of these unless the paths are blocked in some way, or our attention
leads off in some other direction.

FACTORS DETERMINING DIRECTION OF RECALL.--_Which_ of these we get first,
which of the images the taste percept calls to take its place as it
drops out of consciousness, will depend, other things being equal, on
which center was most keenly active in the original situation, and is at
the moment most permeable. If, at the time we were eating the stolen
fruit, our thoughts were keenly self-accusing for taking the apples
without permission, then the current will probably discharge through
the path gustatory-thought, and we shall recall these thoughts and their
accompanying feelings. But if it chances that the barking of the dog
frightened us badly, then more likely the discharge from the taste
center will be along the path gustatory-auditory, and we shall get the
auditory image of the dog's barking, which in turn may call up a visual
