  In this paper we apply the constructor-theoretic approach to the theory of
constructed emotions, showing that core affect valence and knowledge can be
considered as two different observables, leading to information or
superinformation conditions: this depends on subject's strategy, coherently
with the affect infusion model. In the second part of the article we show that
additional hypotheses on the structure of information allows to study emotions
in terms of the contructor-theoretic version of phase task. Quantum algorithms
are presented as an example of the connection between emotions and memory
tasks.
