Abstract: Cognitive ageing in developing societies is marked with psychosocial issues such as education, occupation, lifestyle, social support, social interaction and exclusion that may affect cognitive–affective–behavioural changes with ageing. We also present a study based on cognitive profiling of young (N = 79), middle-aged (N = 54) and older adults (N = 43) in India, which examined learning and memory for verbal and visuospatial information, overall cognitive functions, subjective complaints about cognitive difficulties, neuropsychiatric problems, anxiety and emotion regulation. The study shows cognitive changes compared to young and comparable rate of learning and retrieval among middle-aged and older adults for verbal and visuospatial material, correlated with general cognitive ability. The subjective complaints were not correlated with the objective measures of cognitive functions, highlighting the importance of both to show early cognitive changes. The relationship between cognitive functions and emotion regulation or behavioural/emotional changes was observed for young and middle-aged adults but not for older adults. Findings are discussed in the context of the lifespan perspective of cognitive ageing, cognitive reserve, psychosocial environment and social–emotional selectivity theory.
