Cognitive, perceptual-speed, and psychomotor determinants of individual differences during skill acquisition

The authors describe a series of experiments that explore 3 major ability d eterminants of individual differences in skill acquisition in the context o f prior theory (e.g., P. L. Ackerman, 1988) and subsequent empirical and th eoretical research. Experiment 1 assessed the predictability of individual differences in asymptotic skill levels on the Kanfer-Ackerman Air Traffic C ontroller (ATC) task. Experiment 2 provided an exploration of the construct space underlying perceptual-speed abilities. Experiment 3 concerned an eva luation of theoretical predictions for individual differences in performanc e over skill development in a complex air traffic control simulation task ( TRACON) and the ATC task, with an extensive battery of general and perceptu al-speed measures, along with a newly developed PC-based suite of psychomot or ability measures. Evidence addressing the predictability of individual d ifferences in performance at early, intermediate, and asymptotic levels of practice is presented.
