Unitary Resource and Multiple Resource Models
According to the unitary resource model of attention, there is a single resource of attention divided among different tasks in different amounts, and attention is voluntarily shifted when demands on attention needed exceeds the limited supply of attentional resource available. In contrast, there are also multiple resource models of attention that propose that different attentional resources exist for different sensory and response modalities, which would mean that tasks requiring different senses or different kinds of responses should be easier to switch attention to and from, and that switching costs would be less for similar tasks than tasks that involve different resources.
