ICI Edition

A key notion of pivotal significance, introduced into quantum physics by Niels Bohr, is the notion of complementarity. Broadly speaking, descriptions are complementary if they are incompatible with one another and yet all together needed for a complete picture of the situation described. In quantum physics, this can be precisely formalized by the non-commutativity of system properties. But Bohr always insisted that the actual meaning of complementarity far exceeds the limits of physics. Recent work by several research groups worldwide shows that this idea is indeed viable. Examples in psychology include decision making, learning, associative memory, and order effects in questionnaires. A further interesting example is the perception of ambiguous stimuli which is addressed in particular.
