Notas: Sumario: Technological innovation increasingly requires operators in various applied settings to maintain vigilance for extended periods. However, standard psychometric tests typically predict less than 10% of performance variance. The present study (N = 462) aimed to apply the resource theory of sustained attention to construct a multivariate test battery for predicting battlefield vigilance. The battery included cognitive ability tests, a high-workload short vigilance task and subjective measures of stress response. Four versions of a 60- min simulated military battlefield monitoring task were constructed to represent different operational requirements. The test battery predicted 2444% of criterion variance, depending on task version, suggesting that it may identify vigilant operators in military and other applied contexts. A multiple-groups path analysis showed that relationships between ability and vigilance were moderated by working memory demands. Findings are consistent with a diffuse theoretical concept of resources¿ in which performance energisation depends on multiple, loosely coupled processes.Registros relacionados: En: Ergonomics : the international journal of research and practice in human factors and ergonomics. - Oxon [United Kingdom] : Taylor & Francis, 2010- = ISSN 0014-0139. - 02/06/2014 Volumen 57 Número 6 - junio 2014 Outras classificações: 875
