title: Evidence of construct similarity in Executive Functions and Fluid Reasoning abilities.
abstract: Executive Functions and Fluid Reasoning are both considered to be core aspects of intelligence and mediated by frontal lobe functioning. However, both constructs considerably overlap, and the distinction between the two constructs is unclear. For this study, three measures of Executive Functions and three measures of Fluid Reasoning were administered to a group of participants. Significant correlations were found establishing an empirical association between these two constructs. Factor analysis and confirmatory factor analysis also provide evidence for construct similarity. Future research in defining these constructs for measurement purposes and using tests of these constructs in clinical practice is discussed.
