The primary aim of this study was to examine the relationship between a new battery of everyday cognition measures, which assessed 4 cognitive abilities within 3 familiar real-world domains, and traditional psychometric tests of the same basic cognitive abilities. Several theoreticians have argued that everyday cognition measures are somewhat distinct from traditional cognitive assessment approaches, and the authors investigated this assertion correlationally in the present study. The sample consisted of 174 community-dwelling older adults from the Detroit metropolitan area, who had an average age of 73 years. Major results of the study showed that (a) each everyday cognitive test was strongly correlated with the basic cognitive abilities; (b) several basic abilities, as well as measures of domain-specific knowledge, predicted everyday cognitive performance; and (c) everyday and basic measures were similarly related to age. The results suggest that everyday cognition is not unrelated to traditional measures, nor is it less sensitive to age-related differences. The present study was conducted to address two questions regarding older adults' cognitive performance with problems drawn from everyday life. First, the validity of several newly developed cognitive assessments using "everyday" stimuli was assessed. Specifically, in this study we examined the relationships between traditional psychometric measures and a new battery of everyday intellectual tasks. Second, within an ethnically heterogeneous sample of older adults ranging from 60 to over 90 years of age, we investigated whether age differences found with everyday cognition measures were similar to those found with psychometric ability tests or whether the greater familiarity and relevance of tasks using real-world stimuli might attenuate cross-sectional age differences as some theorists have proposed. For the purposes of this study, everyday cognition was conceptualized as the performance of individuals on problems using natural stimuli (e.g., real food package labels or official documents), and the problems were constructed to be similar to tasks older individuals might actually be called on to perform in their daily lives (e.g., identifying nutrition information or comparing the value of different financial products). This study is embedded in a larger body of research concerned with understanding the cognitive performance of individuals in the context of their daily lives. Specifically, proponents of the ecological approach have maintained that in the real world individuals can draw on domain-relevant experiences and naturalistic motivations to enhance their cognitive performance (e.g., Ceci & Bronfenbrenner, 1991; Neisser, 1978, 1991; Weisz, 1978) and that relatively "acontextual" laboratory-based assessments of cognition may produce an underestimation of true performance competencies (Bronfenbrenner, 1979; Conway, 1991; Wagner, 1986). Historically, it has also been argued that traditional or academic measures of cognition and intelligence are biased tow...
