As an illustrative example, Figure 1 demonstrates the undesirable effects of ceiling-limited data on the magnitude of age declines on low versus high demand prospective memory tasks included in Henry et al.'s [14] meta-analysis.
Henry et al. [14] reported an average effect size for low (r = −.14 or d = −0.28) versus high (r = −.40 or d = −0.87) demand conditions, together with the required ks, Qs, and ps, and concluded that age declines are much smaller in low demand than in high demand prospective memory tasks.
These observations imply complex relationships between use and resistance, demanding prospective investigation.
Because a number of studies have shown that higher ongoing task demands reduce prospective memory performance, making the ongoing task easier for older adults artificially reduces the size of age differences in prospective memory performance and makes it impossible to disentangle effects of aging from effects of giving older adults easier ongoing task.
We designed this study to estimate the future cancer burden and to highlight the demands on prospective healthcare resources.
Linda Martynkova, senior property consultant for Svoboda & Williams, says there is a shortage of new luxury developments, and when there is one, parking is one of the most common demands from prospective buyers.

Until the 1990s, foreign domestic helpers mostly came from the Philippines; since then, to cope with the different demands of prospective employers, the percentages have been shifting away from Philippine helpers, in favour of Indonesian and other nationalities.
However, the small number of patients used for this study demands further prospective studies in larger populations to confirm these results and to assess its value in clinical practice.
As a result, some goods and services are not traded in markets, despite potential demand and prospective supply.
