Interface changes causing accidents. An empirical study of negative transfer

Abstract

International audienceWhen expert operators interact with a new device, they inevitably reuse former interaction modes and actions. This phenomenon is due to the human cognition seeking resources savings. Schemas support this strategy and are implemented in such a way that perfection is disregarded at the profit of an intuitive trade-off between performance and cognitive resources savings. As a consequence, humans have a strong inclination to fit well-known solution procedures into new problems. For this reason, changes in work environments can cause accidents when they allow operators to interact with a new device if the latter is erroneously perceived as familiar. This research issue originates from an industrial background. The suspected cause of a fatal error performed by an operator in a steelworks factory is replicated in an experiment. The results support the hypothesis according to which errors (and possible subsequent accidents) due to changes in the interface are more likely when the latter does not inhibit former modes of interaction modes. This main result is discussed under the angle of cognitive ergonomics and used as a basis to provide design guidelines

Examining working memory load and congruency effects on affordances and conventions

“…The results of Still and Dark (2008) and others (e.g., Besnard and Cacitti, 2005) suggest that because conventions reflect expectancies, it may also be important for designers to respect conventions. We examined the cost of violating the expectancies in affordance-based and convention-based interactions (as operationalized by incongruent mappings).…”

Combining situated Cognitive Engineering with a novel testing method in a case study comparing two infusion pump interfaces

“…We applied the Goals, Operators, Methods, and Selection rules (GOMS) model (John and Kieras, 1996) as a framework for data coding to achieve a formal representation of task execution processes. In addition, introduction of novel interaction design requires initial learning (MacKenzie and Zhang, 1999) and may even be hampered by inappropriate transfer (Besnard and Cacitti, 2005). In order to capture performance differences beyond the first encounter, we explored the impact of task repetition on performance.…”

Past Success and Creativity over Time: A Study of Inventors in the Hard Disk Drive Industry

“…This prediction is supported by considerable psychological research on cognitive framing which suggests that when people have experienced success with a particular strategy, they often become narrowly focused on implementing that particular strategy to solve new problems (Duncker, 1945;Luchins, 1942). This type of mental block is called "negative transfer" (Bartlett, 1958) and it has been found to deter the generation of novel solutions in a variety of situations such as negotiations over time (Bareby-Meyer, Moran & Unger-Aviram, 2004), factory operation after a change in accident monitoring devices (Besnard & Cacitti, 2005) and firms acquiring targets from different industries (Finkelstein & Haleblian, 2002).…”
