The model of selective optimization with compensation proposes that successful aging is related to three main factors. which of these factors is based on the concept that, in old age, there is a reduced capacity and loss of functioning that mandate a reduction of performance in most domains of life?

This is the selection domain. In this factor, the person will begin to lose their acuity at certain tasks, which can then lead to the other two propositions in the model: optimization or compensation. With optimization, the person can maintain their performance level via practice or technology, while compensation holds that there are simply some domains that are outside the bounds of typical human performance at a certain age and potential.
