Previous research has suggested that an age-related decline in change detection may be due to older adults using a more conservative response criterion. However, this finding may reflect methodological limitations of the traditional change detection design, in which displays are presented continuously until a change is detected. Across 2 experiments, the authors assessed adult age differences i...

Following the procedure used by Zemore and Eames (1979) with the Beck Depression Inventory, the 20 items of the Zung Self-Rating Depression Scale were categorized as either somatic or psychological symptoms of depression. Scores of 179 college students and 462 community-dwelling older adults revealed significant, though small, age differences in somatic complaints. Somatic complaints were espec...

BACKGROUND Substance use and sexual risk behaviour affect young people's current and future health and wellbeing in many high-income countries. Our understanding of time-trends in adolescent health-risk behaviour is largely based on routinely collected survey data in school-aged adolescents (aged 15 years or less). Less is known about changes in these behaviours among older adolescents. METHO...

BACKGROUND HIV-1 prevalence typically rises more rapidly at young ages in women than in men in sub-Saharan Africa. Greater susceptibility to infection on exposure in women is believed to be a contributory factor as is greater exposure to previously infected sexual partners of the opposite sex. We investigated the latter hypothesis using data from a field study in rural Manicaland, Zimbabwe. M...

Leucocyte ascorbic acid (L.A.A.) levels and vitamin C intake were measured in a random sample of men and women aged 62-94 years. L.A.A. distributions are positively skewed but log normal. L.A.A. mean values show no age difference in men but are significantly lower in older women. The mean value for all women (23.88mug/10(8) cells) is significantly higher than that for all men (18.11 mug/10(8) c...

In 2 studies, 6-, 8-, and 10-year-0ld children were interviewed about 3 different types of regularities or rules social conventions, physical laws, and logical necessities. In the first study, children were asked if regula...

Previous research revealed age differences in following the gaze of others. To date, however, investigations have concentrated on only young faces as target stimuli. The present study explored whether varying the age of target stimuli moderated gaze following in younger and older adults. Overall, older participants showed less evidence of gaze following, but this was qualified by the age of the...

Previous work suggests that older adults show a stronger correspondence bias than do young adults. In the present study we examine whether age differences in the correspondence bias are universal or if they differ across cultures. A sample of young and older adults from China completed an attitude-attribution paradigm. We compared these data with an existing American data set. We found cultural...

Adults from a wide range of ages were administered parallel versions of three memory tasks designed to involve verbal-symbolic information or visual-spatial information. Several analytical procedures were used to determine whether there were selective age-related effects on measures reflecting spatial information processing compared to those reflecting verbal-symbolic information processing. Th...

Children and adults were escorted on their first walk across our university campus and were periodically led off the original route during the return trip. During the return, we stopped prior to intersections on and off the original route to obtain estimates of place recognition accuracy and confidence. The subjects were then asked to point to the path that led back to the start and were correc...
