Step-by-step explanation:
A polychronic culture refers to a culture where people engage in multiple tasks simultaneously and have a more fluid perception of time. In these cultures, people value personal relationships and prioritize social interactions over strict adherence to schedules and deadlines. This cultural trait can impact task performance because it emphasizes collaboration and flexibility over strict efficiency and time management. For example, in a polychronic culture, individuals may spend more time discussing ideas and building consensus, which can lead to slower task completion but greater overall satisfaction and effectiveness.
