Form appears to be a property
capable of eliciting or
"releasing" instinctual
reactions in other species as
well. For example, herring-gull
chicks, on the day after
hatching, will "beg" far more
frequently at a model whose
shape resembles the bill of the
parent than at models of other
shapes. No such preference
could be manifested unless the
capability of form perception
itself was present from birth.
Human infants also show
preferences with respect to
what shapes they will look at
during extended periods of
observation. To discover such
preferences, psychologists
monitor the direction of the
infantΓÇÖs gaze. The object at
which the infant looks is
reflected off the cornea over
the pupil of the eye. The
experimenter can simply clock
the amount of time spent
looking at one thing or another
or, better yet, can record the
session on film or videotape
and analyze it later. In recent
research, the infantΓÇÖs eye
movements are accurately
determined by an apparatus
that tracks the eyes.
