It is believed that many new jobs found in the automated workplace are likely to be sensitive to state-dependent changes in human functioning due to their level of cognitive-oriented task requirements over the more traditional workplace jobs. Two special issues of Human Performance describe a diverse set of laboratory and field research interests that fall within the broad domain of state-dependent human cognition and performance.
Part I explores a laboratory analogy to a complex task environment where specific task characteristics alter cognitive functioning and performance in rather unique ways when evaluated within the context of complex decision making. The contributors examine the theoretical and applied dimensions to the concept of arousal and its relationship to memory for everyday events. They also offer suggestions for a better model on the linkage between arousal and memory performance by analyzing the research on autobiographical memory and memory for real-world information. Finally, they discuss the intimate relationships among sleep, cognitive functioning, and work behavior while attempting to highlight the importance of sleep for optimal cognitive processing and effective job performance.
