In education, a general term for areas of learning and behavior, introduced in the 1950s by Benjamin Bloom and referring to three key categories of instructional content and learning objectives: affective domain, cognitive domain, and psychomotor domain. The affective domain refers to feelings, emotions, values, and attitudes (affect being a psychological word for shown feelings). The cognitive domain covers thinking skills such as problem-solving, memory and recall, comprehension, reasoning, and judgment. The psychomotor domain refers to a child’s physical and muscular functioning. These domains are often referred to by educators planning a curriculum, as in an individualized education plan for a handicapped child, with specific learning objectives planned for each area. The term domain has also been used to refer to other categories of learning.
