Previous studies have manifested a strong relationship between socio-economic status (SES) and cognitive abilities in young children, however, the effects of SES on developed cognitive architecture remain less explored. The current study examined whether and how cognitive processing differs as a function of socioeconomic status in adults. The performance measured individuals from lower and higher SES (29.9 ± 8.2 years, Male = 81, Female = 19) on tests of working memory (Digit Span), visuo-spatial memory (visual retention and recognition) and executive functioning (Stroop test and Koh’s block test). Lower SES adults had significantly lower test scores on all the measures as compared to the higher SES adults. These findings suggest that lower SES individuals exhibit lower cognitive abilities as compared to the individuals associated with higher SES. The current findings append to the previous literature by demonstrating a significant interaction between SES and cognitive processing in adults.
