Cognitive neuroscience literature suggests a strong dissociation between the ability to mentally transform object and body stimuli (Hegarty Waller, 2004). However, little is known about how this ability changes with age. This dissociation was explored in 20 younger (19-24 years) and 20 older (65-87 years) adults. Mental rotation of object stimuli was demonstrated for both age groups, suggesting that the neuro-cognitive network involved with performing (object-based) mental transformations is relatively preserved in older age. Compared to young adults, older adults displayed the greatest decline in performance efficiency for the whole-body task. The authors propose that an age-related decline in the integrity of body-schema information may account for this change.
