It may or may not alter your perception of an object when you begin to
be able to identify it as an "X." It could make you SEE it AS an X, and
the features you select to do this may highlight some aspects of it and
suppress others. Do you think you are seeing them the same way after you
have learned to recognise cells, and even animal and plant cells, under
a microscope?

Learned biases and expectations, based on previously learned categories,
can slow down new categorisations just as innately "prepared" biases and
expectations can.
