Abilities and skill acquisition: A latent growth curve approach

Differential effects of intelligence, perceptual speed and age on growth in attentional speed and accuracy

“…Several researchers have investigated the relation of growth curve parameters, i.e., baseline performance and performance growth, to intelligence and other predictors to investigate determinants of individual differences in skill-acquisition (e.g., Jones et al, 2005;Voelkle, Wittmann, & Ackerman, 2006) or the specificity of learning ability with respect to task material (e.g., Zhang, Davis, Salthouse, & Tucker-Drob, 2007). These studies provide some support for Ackerman's theory.…”

“…These studies provide some support for Ackerman's theory. The study by Voelkle et al (2006) using a task simulating the activities of an air traffic controller suggests that spatial-numerical ability is a stronger predictor of interindividual differences in baseline performance, while perceptual speed is a better predictor of performance growth. Zhang et al (2007) used multitrial verbal Fig.…”

“…Multivariate normality could not be shown for indicator variables. Therefore, parameters were estimated using the MLM estimator implemented in the Mplus 4.21 program (Muthén & Muthén, 1998-2006, which provides maximum likelihood estimates with standard errors as well as a meanadjusted chi-square test statistic (Satorra-Bentler correction; see Satorra & Bentler, 1994) which are both robust to non-normality.…”

Fluid intelligence as a predictor of learning: A longitudinal multilevel approach applied to math

“…As was pointed out by Voelkle et al (2006), one important difficulty in the study of the relationship between ability and learning is the determination of actual acquisition of a specific skill or concept. Usually studies use a measure of learning at a single point in time as the criterion to be predicted.…”

Aging trajectories of fluid intelligence in late life: The influence of age, practice and childhood IQ on Raven's Progressive Matrices

“…Practice effects of this type may be greater in individuals with higher original intelligence (IQ). Research using delayed growth models to evaluate patterns of skill acquisition suggests that baseline ability predicts rate of learning (Voelkle, Wittmann, & Ackerman, 2006). Longitudinal studies of IQ in children also provide evidence of the "Matthew effect" (Merton, 1968;Stanovich, 1986) whereby children with higher baseline IQ show more of an increase in IQ with repeated testing over time (Shaywitz et al, 1995).…”
