Why does that TV remote feel so unnatural? Why did a nuclear power plant's own control panel work against its operators? This lesson explores human factors psychology (also called ergonomics), the science of designing machines, workstations, and software systems that fit the physical and cognitive limits of real people. Drawing from Section 13.4 of OpenStax Psychology 2e, we trace the field from its roots with pioneers Lillian and Frank Gilbreth all the way to modern cybersecurity failures. In this video: • How human factors psychology differs from other areas of I-O psychology, focusing on the individual worker's interaction with machines and environments • The Three Mile Island nuclear accident as a landmark case of interface failure — and how it drove new NRC regulations and ANSI ergonomic standards • Why checklists (like the WHO surgical safety checklist) and FAA pilot duty-time limits serve as cognitive backstops in high-stakes industries • Bruno & Abrahão's (2012) study of 45,000 decisions at a Brazilian bank, showing how cognitive overload leads to more false alarms • The 2013 Target data breach as a real-world contrast — where alarm fatigue caused security personnel to miss a genuine threat for two weeks • The layered framework of task analysis, cognitive task analysis, and cognitive engineering for understanding how workers make decisions • How the future of human factors psychology may shift toward managing human-algorithm disagreements in increasingly automated systems #HumanFactors #Ergonomics #IOPsychology #OpenStax #CognitivePsychology OpenStax Content adapted from "OpenStax Psychology 2e", by OpenStax licensed under CC BY 4.0.
