Final answer:
Anna is likely to be motivated by self-actualization needs according to Maslow's hierarchy of needs, as she has already met her lower-level needs.
Step-by-step explanation:
According to Abraham Maslow's hierarchy of needs, after fulfilling physiological, safety, social, and esteem needs, an individual like Anna who has been recognized for her excellence and feels respected and admired by her peers, would next be likely motivated by self-actualization needs. Given that Anna has already met her social needs through respect and admiration at work and likely her safety needs by being employed for several years, her next source of motivation would move towards self-actualization. This highest level in Maslow's pyramid represents the drive to achieve one's full potential and realize personal growth, creativity, and fulfillment.
