Aging causes a series of neurocognitive changes. Objective: to validate a proposal for an explanatory model of neurocognitive functioning based on Inhibitory Control, Working Memory, and Processing Speed of the elderly. Design: explanatory multivariable. Sample: 128 participants between the ages of 60 and 85. Instruments: Brief neuropsychological evaluation in Spanish called Neuropsi, Stroop color and word test, working memory and processing speed subtests from the Wechsler Adult Intelligence Scale/WAIS-IV. Analysis method: structural equation modeling Results: Two explanatory models were proposed. Model I included the entire sample where inhibitory control is the variable that is significantly associated with and explains neurocognitive functioning (β=0.222; p<0.538). Model II included age as a control variable: determining that processing speed best explains neurocognitive functioning in adults aged 60 to 70 years (β=2.329; p=0.030). None of the variables show a significant relationship in adults aged 71 to 85 years. However, this model obtained better adjustment indexes CMIN/DF= 1.352; GFI = .950; CFI = .983 and RMSEA = .053. Conclusions: Inhibitory control explains neurocognitive functioning in adults aged 60 to 85 years and processing speed in adults aged 60 to 70 years, which validates the explanatory model of neurocognitive functioning that considers age as a control variable. On the other hand, processing speed and working memory are significantly associated in all stages of aging.
