What indicates a person's perception that their actions have a significant impact on the environment or task?

The correct answer is that the concept indicating a person's perception that their actions have a significant impact on the environment or task is encapsulated in the term "Impact." In the context of psychological empowerment, impact refers specifically to the belief that one’s efforts make a difference in the outcomes of tasks or the organization as a whole.

When individuals feel that they are able to affect outcomes, it can significantly enhance their motivation and sense of agency. This perception fosters a sense of responsibility and ownership over their work, leading to increased engagement and productivity. Impact is one of the core components that contribute to a person’s overall sense of empowerment in their role.

Meaningfulness relates to the value of the work performed, while competence pertains to one’s belief in their abilities to perform tasks effectively. Psychological empowerment, as a broader construct, incorporates these elements (meaningfulness, impact, and competence) but is more comprehensive and includes the overall perception of self-efficacy and the significance of one’s contributions. Therefore, while each of the other options contributes to the broader understanding of empowerment, "Impact" directly addresses the feeling that one's actions lead to significant changes in the environment or task.
