Contextual explanation: Focused awareness on a problem. 
Problem attention is best understood as a cognitive process—specifically, the deliberate concentration of awareness on a problem that requires recognition, examination, or resolution. It marks the moment when an issue becomes the primary object of thought, enabling deeper analysis and potential problem-solving.

Themes: Recognition and cognitive prioritisation. 
Problem attention is central to the theme of recognition, as it involves identifying and acknowledging the presence of an issue. It also relates to cognitive prioritisation, since it determines which problems receive mental resources and focus at any given time.

Nuance: Deliberate mental focus on issues. 
What distinguishes problem attention within its category is its intentional and selective nature—the focus is not just on any stimulus, but specifically on problems that demand awareness and action. This sets it apart from general attention, as it is purposefully directed toward challenges or obstacles requiring resolution.
