<p>With an increase in the aging population, successful aging has become a worldwide requirement. Healthy cognitive functioning is an essential element of successful aging. Therefore, the present study intended to examine the influence of perceived social support and life purpose on cognitive functioning. The present study has employed a correlational research design. The sample comprised 140 middle-aged adults (ages 35 to 55 years) who were recruited through the purposive sampling technique. Montreal Cognitive Assessment (MoCA), Purpose in Life scale and Multidimensional Scale of Perceived Social Support (MSPSS) were used as assessment measures. Findings indicated that cognitive functioning has a significant positive relationship with life purpose and perceived social support. Furthermore, purpose in life and family and friends support found to explain the significant amount of variance in cognitive functioning even after controlling for the effects of age and education of the participants. To conclude, a higher sense of purpose in life and perceived social support tend to protect cognitive functioning in middle age. Therefore, the present study findings have implicated a practical way for healthcare providers for the prevention of cognitive impairment and promotion of successful aging.</p>
