Final answer:
The study by Benner emphasizes the importance of experiential knowledge, which is a form of a posteriori knowledge gained through experience in the healthcare industry.
Step-by-step explanation:
The study conducted by Benner (1984) highlights the development of clinical knowledge and expertise through experiential knowledge. This type of knowledge is gained through the practical application of skills and understanding in real-life situations, as opposed to purely theoretical or book knowledge. Nurses and other healthcare professionals acquire this empirical knowledge through lived experiences and practice, which allows them to become proficient in their field. Considering the nuances of epistemology, experiential knowledge falls under the category of a posteriori knowledge, which is based on experience and empirical evidence. Benner's research emphasizes how such knowledge is crucial for the development of expertise in nursing and healthcare.
