What is Attention Deficit Principle

Attention is a term commonly used in education, psychiatry, and psychology. Attention can be defined as an internal cognitive process by which one actively selects environmental information (i.e., sensation) or actively processes information from internal sources (i.e., stored memories and thoughts; Sternberg, 1996). In more general terms, attention can be defined as an ability to focus and maintain interest in a given task or idea, including managing distractions. Attention is selective by its nature. According to Pashler (1998, p. 37), “The process of selecting from among the many potentially available stimuli is the clearest manifestation of selective attention.”
