Final answer:
The provided text does not explicitly describe a paradoxical intervention, which is a therapeutic technique used to encourage patient self-awareness and change by prescribing the problem behavior. Instead, it alludes to relationship issues that might benefit from such an intervention.
Step-by-step explanation:
The excerpt given seems to describe a situation where someone is constantly checking on their partner's whereabouts. This scenario may illustrate a concept in psychology known as paradoxical intervention. However, the information provided does not detail a typical paradoxical intervention, as such interventions are strategies used by therapists to encourage a patient to embrace a particular behavior or emotion deemed problematic, with the goal of triggering self-awareness and change. Paradoxical intervention is a therapeutic technique that often involves prescribing the symptom or problem or encouraging a patient to exaggerate problematic behaviors. In the given text, the individual is attentive, but there is a suggestion of underlying issues in the relationship such as lack of trust or an imbalanced dynamic where one person is 'so sure' of the other's feelings. This can relate to behaviors in relationships that might require intervention, but without more context, it's hard to categorize it as a paradoxical intervention used in therapy.
