Abstract
The concept of compounding of different abilities into a specific capability was demonstrated by Spearman (1905) and Mcgrew (1997) for the Cattell Horn Carroll Model using factor analysis but has remained unexplored since then and the effects of nurturing elements has also remained unresolved. This study investigated the Extended Model of Giftedness and Talent (EMGT) based on the compoundability hypothesis and the effects of nurturing elements such as environment and motivation on the development of giftedness and talent across the intellectual domain by developing new instruments and test items and employing statistical validation procedures using Structural Equation Modelling (SEM). The instrument consisted of culture-reduced test items that incorporated Cattell’s Culture-Fair Test (CCFT) items and tested for six standard subscales of intellectual aptitudes such as memory span, pattern recognition, sense of observation, spatial-matrices, problem solving, and visual-spatial ability and four new intellectual aptitude subscales suggested by the EMGT model, namely, audio-matrices, audio-spatial, audio-logic, and artificial language. The sample consisted of 374 high ability students selected from nine schools at a leading university in Malaysia. All data collection procedures were done through online facilities and data were automatically coded and processed when the answers were submitted.
The findings showed that the elements of giftedness combined to form significantly different compounds of abilities and four compounds of internal factors, namely, Spatial, Reasoning, g, and Motivation, and one external factor, namely, Environment were extracted. The results for the competing model showed that the model fitted the data with two distinguished compounds of giftedness, namely, the spatial
compound and the reasoning compound being extended from g compound with significant support from motivation and environment.
