An approach to human performance based on economic concepts Is drscribed.<br />

It elaborates on the view that the buman system employs utility considerations<br />

to decide on allocation of its limited rnources. The efficiency of tbose resources<br />

for performina a task depends on parameters chancleriring the lask and the<br />

performer. This approach is ant used to discoss various modeb and interpretations<br />

for dual-task performance and their predictions, subject to the assumpt-ion<br />

that there is a single pool of resources. An tapansion of this approach is<br />

then prnented that hinges on the idea that the human-procnsing system incoa<br />

. .. poraln a number of inechanisms, each hasing its own capacity. Those capuitin<br />

can at any moment be allocated among several processes. Empirical esidenct<br />

relevant to this idea and new interpretations for phenomena of dual-task<br />

performance suggested by it are presented.<br />
