DESCRIPTION:There exists a growing need for adaptive functional materials.
  Could materials showing a response to a particular stimulus become respon
 sive to another stimulus to which they are originally indifferent? Such be
 havior would mimic classical Pavlovian conditioning in behavioral psycholo
 gy\, one of the elementary forms of learning. This would conceptually diff
 er from conventional stimuli-responsive and shape memory materials\, where
  no new stimuli become activated to allow the same response. Here we demon
 strate soft matter systems programmed to show classical conditioning\, all
 owing to respond to an initially neutral stimulus (light) after a conditio
 ning process\, where the neutral stimulus is associated with an unconditio
 ned stimulus (heat). Inspired by the biological processes\, we also show "
 forgetting" and "recovery" by out-of-equilibrium processes\, incorporating
  tools from systems chemistry. We suggest generalizations for other stimul
 i and materials emulating algorithmically the elementary mechanistic aspec
 ts of learning.
