In contrast to cognitive psychology and human factors, which typically focus on the characteristics of the “average” person, psychometrics is concerned with explaining differences between people. New developments in molecular genetics and bioinformatics now make it possible to supplement the psychometric approach to identify sources of individual differences in human performance. Noting that many performance laws in applied psychology do not adequately capture individual differences, the chapter introduces a neuroergonomics approach to individual performance prediction based on molecular genetics and neuroscience. It breaks new ground in the effort to provide a neural and genetic basis for characterizing individual differences in various cognitive functions, including attention and memory. The initial goal is to be able to identify single genes that are associated with individual differences in elementary cognitive operations underlying attention and working memory. The chapter hopes to show that the work has relevance to the “applied attention” theme of this book by pointing out the routes toward application, much in the spirit of Christopher Wickens' research, which epitomizes theory-based application.
