This chapter examines the sensory and intellectual components of attention. Investigations reveal that certain sensory and intellectual sensations combine to form attention, which can also be viewed as a focus on specific tasks or issues. People find it difficult to remain focused after losing interest in an object or a given task. Attention has also been associated with consciousness, demonstrating that it is an activity which creates ideas in the conscious state of the brain in varying degrees. The realm of attention can narrow or widen, depending on the degree of consciousness. Advanced neurophysiology and brain imaging techniques have driven significant progress in gathering information about brain mechanisms involved in attention. They have also helped us to better understand attention through conducting experiments in conscious and subconscious states in animals and humans.

Keywords:   attention, sensory, intellectual ingredients, consciousness
