A growing interest is to determine whether hippocampal volume (HV) predicts basal and/or reactive cortisol levels in young and older adults. Recent evidence shows that contextual features in testing environments might be stressful and inadvertently induce a stress response in young and/or older populations. This latter result suggests that variations in testing environments might influence associations between HV and cortisol levels in young and older adults. To this end, we investigated 28 healthy young adults (ages 18-35) and 32 healthy older adults (ages 60-75) in two different environments constructed to be more or less stressful for each age group (Favoring-Young versus Favoring-Old conditions). Cortisol levels were repeatedly assessed in each environment, and young and older participants underwent an anatomical magnetic resonance imaging scan for subsequent assessment of HV. Results in both age groups showed that HV was significantly associated with cortisol levels only in the unfavorable stressful testing conditions specific for each age group. This association was absent when testing environments were designed to decrease stress for each age group. These findings are fundamental in showing that unless the nature of the testing environment is taken into consideration, detected associations between HV and cortisol levels in both young and older populations might be confounded by environmental stress.</dcterms:abstract> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2017-04-03T11:05:32Z</dcterms:available> <dc:contributor>Lord, Catherine</dc:contributor> <dc:creator>Juster, Robert-Paul</dc:creator> <dc:contributor>Juster, Robert-Paul</dc:contributor> <dc:creator>Fiocco, Alexandra J.</dc:creator> <dc:contributor>Fiocco, Alexandra J.</dc:contributor> <dcterms:issued>2014-12</dcterms:issued> </rdf:Description> </rdf:RDF>
