| 摘要： | The goal of the current research program was to select a critical subset of task conditions and individual differences variables and evaluate the joint effects of these variables on task performance in a complex-skill environment. The subset of task conditions selected were those that involve basic processes of working memory, task monitoring, and differential loads on spatial reasoning and speed of perceiving. The subset of ability determinants of performance included broad content abilities (spatial and math abilities), perceptual speed abilities (including complex perceptual speed, scanning, memory and pattern recognition). A complex task platform was adopted that simulates many aspects of the job of an air traffic controller. Manipulations of task component demands and communication channel reliability were used to evaluate both overall effects and moderating effects on ability - performance relations. Manipulations of task characteristics proved to be highly effective in changing the mean levels of task performance. However, critical ability measures were demonstrated to be robust predictors of performance, even under substantially altered task constraints. Implications of these findings are discussed with respect to extant theory and empirical research. In addition, brief discussion is provided regarding the potential applications of these findings for operational environments. |
