The impedance bridge test is a sensitive and objective measure of the integrity and function of the middle ear. Tympanograms obtained from children with a specific reading disability were compared with those from a matched group of controls. A significantly higher prevalence of defects of the middle ear was shown in the test group.

Using the Canadian National Population Health Survey and the recent tax variation across Canadian provinces, this paper examines the impact of cigarette taxes on smoking participation. Consistent with the literature, we find evidence of a heterogeneous response to cigarette taxes among different groups of smokers. Contrary to most studies, we find that the middle age group-which constitutes the...

In general there is a slow decline in physical performance during maturity which becomes more rapid with increasing age. Maximum oxygen uptake ('Y02 max) is regarded as one of the best measurements of physical working capacity; and cross-sectional studies suggest that men lose about 11-14ml.kg-lmin-1 of aerobic power between the ages of 25 and 55 years (Astrand and Rodahl, 1977; Quirion et al, ...

Age-related changes in temporal order memory have been well documented in older adults; however, little is known about this ability during middle age. We tested healthy young, middle-aged, and older adults on a previously published visuospatial temporal order memory test involving high and low interference conditions. When interference was low, young and middle-aged adults did not differ, but b...
