A Taxonomy of Self-Estimated Human Performance

Previous research often examined self-estimated intelligence in relation to academic models of human cognitive ability or popular models of intelligence (e.g., Gardner's (1983) multiple intelligences). The present study employed a different concept of ability, namely, Fleishman's (1975) structure of human performance, to investigate the psychometric structure of self-estimates. A structural equation model generally confirmed Fleishman's apriori taxonomy. In addition, the structure of self-estimated abilities closely resembled models of measured cognitive ability (e.g., Carroll, 1993) and one latent trait, termed general factor ί, was identified. Modest sex differences in self-estimated ability were confirmed in favor of men; however, the latter were noteworthy only for the domains of spatial orientation and physical strengths. Implications for research and practice are discussed.
