Objective: This paper considers the influence of "Humans and Automation: Use, Misuse, Disuse, Abuse" and examines how it relates to the evolving issue of human-automation interaction. Background: Automation presents important practical challenges that can dramatically affect satisfaction, performance, and safety; philosophical challenges also arise as automation changes the nature of work and human cognition. Method: Papers cited by and citing "Humans and Automation" were reviewed to identify enduring and emerging themes in human-automation research. Results: "Humans and Automation" emerges as an important node in the network of automation-related papers, citing many and being cited by many recent influential automation-related papers. In their article, Parasuraman and Riley (1997) integrated previous research and identified differing expectations across designers, managers, and operators regarding the need to support operators as a source of automation problems. They also foresaw and inspired research that addresses problems of overreliance and underreliance on automation. Conclusion: This pivotal article and associated research show that even though automation seems to relieve people of tasks, automation requires more, not less, attention to training, interface design, and interaction design. The original article also alludes to the emergence of vicious cycles and dysfunctional meta-control. These problems reflect the coevolution of automation and humans, in which both adapt to the responses of the other. Application: Understanding this coevolution has important philosophical implications for the nature of human cognition and practical implications for satisfaction, performance, and safety.

Objective: This brief review covers the 50 years of driving-related research published in Human Factors, its contribution to driving safety, and emerging challenges. Background: Many factors affect driving safety, making it difficult to assess the impact of specific factors such as driver age, cell phone distractions, or collision warnings. Method: The author considers the research themes associated with the approximately 270 articles on driving published in Human Factors in the past 50 years. Results: To a large extent, current and past research has explored similar themes and concepts. Many articles published in the first 25 years focused on issues such as driver impairment, individual differences, and perceptual limits. Articles published in the past 25 years address similar issues but also point toward vehicle technology that can exacerbate or mitigate the negative effect of these issues. Conceptual and computational models have played an important role in this research. Conclusion: Improved crashworthiness has contributed to substantial improvements in driving safety over the past 50 years, but future improvements will depend on enhancing driver performance and perhaps, more important, improving driver behavior. Developing models to guide this research will become more challenging as new technology enters the vehicle and shifts the focus from driver performance to driver behavior. Application: Over the past 50 years, Human Factors has accumulated a large base of driving-related research that remains relevant for many of today's design and policy concerns.

This article examines the limitations of the construct of race in the study of the diversity of human development. The author proposes that a focus on ethnicity as relates to people of African descent in the United States offers greater explanatory power. The article acknowledges the value of moving away from social address registers in the study of human development, but cautions that this emerging theoretical orientation should not diminish the stable and enduring patterns of continuity within and across the African-American community. The author argues that the field faces both conceptual and methodological challenges in studying human development in its complexity. She offers additional cautions in terms of methodological approaches that seek to capture that complexity.

Two experiments are presented that serve as a framework for exploring auditory information processing. The framework is referred to as polychotic listening or auditory search, and it requires a listener to scan multiple simultaneous auditory streams for the appearance of a target word (the name of a letter such as A or M). Participants' ability to scan between two and six simultaneous auditory streams of letter and digit names for the name of a target letter was examined using six loudspeakers. The main independent variable was auditory load, or the number of active audio streams on a given trial. The primary dependent variables were target localization accuracy and reaction time. Results showed that as load increased, performance decreased. The performance decrease was evident in reaction time, accuracy, and sensitivity measures. The second study required participants to practice the same task for 10 sessions, for a total of 1800 trials. Results indicated that even with extensive practice, performance was still affected by auditory load. The present results are compared with findings in the visual search literature. The implications for the use of multiple auditory displays are discussed. Potential applications include cockpit and automobile warning displays, virtual reality systems, and training systems.

During the 1990s, legal issues arising from governors exercising their item‐veto powers were prevalent. These issues arose despite the fact that in most instances, state constitutions grant these powers to governors. Also, legal issues were prevalent, even though these powers had been exercised for decades; one might have expected that most legal issues would have been resolved long before the 1990s. Topics in court included standing, advisory opinions, definitions of 'appropriation' and 'item,' reasons used by governors in exercising the veto power, post‐adjournment vetoes, and labor relations in conjunction with item‐vetoes that affect personnel. The item‐veto cases need to be considered in the broader context of state government, which encompasses such topics as initiatives and referenda, biennial budgeting, school desegregation mandates by courts, and balanced budget requirements. No single topic dominated litigation in the 1990s, but instead a breadth of topics was evident.
