Summary
This paper presents a cognitive model explaining how disruptions, interruptions, and information attacks impact situation awareness (SA) and decision-making, particularly within military aviation and air traffic control. The research is motivated by the increasing reliance on information systems in the 21st century and the catastrophic potential of undetected information attacks in aviation. The authors argue that understanding these effects requires examining how decision-makers perceive attacks within the context of everyday operational noise, such as software glitches, system maintenance, and normal user errors. Because malicious cues often resemble benign disruptions, the paper aims to clarify how human cognition processes these ambiguous signals to inform the development of more robust defensive systems. The proposed model categorizes disruptions into four major types that affect different stages of information processing: pre-processing, prioritization and attention, confidence in information, and interpretation. The framework is grounded in prior work on SA and naturalistic decision-making, specifically recognizing that decisions are made against a backdrop of noisy, non-discrete information. The model illustrates how decision-makers must determine if cues represent abnormal events or fit known patterns of typical problems. If cues align with a "normal" mental model, such as routine maintenance, the possibility of a hostile attack may be ignored. The paper details specific mechanisms for each disruption category. Disruptions in information pre-processing involve information overload, dissonance, or delay, which can cause decision-makers to omit key data or slow processing, reducing time for decision-making. Disruptions in prioritization and attention arise from task interruptions that lead to attentional narrowing or misprioritization, causing operators to forget competing goals. Disruptions in confidence occur when information is partially corrupted or sources are deemed unreliable, leading operators to withhold action or inefficiently seek confirmation. Finally, disruptions in interpretation involve inserting cues that mimic normal situations or withholding critical cues, causing decision-makers to pattern-match attacks to benign mental models, thereby explaining away hostile events. The significance of this work lies in its application to designing decision-support tools that can distinguish between normal disruptions and information attacks. The authors conclude that because these attacks exploit natural cognitive processes and frequent operational interruptions, they are difficult to detect. The model provides a basis for analyzing how non-normal attacks are interpreted within normal contexts, suggesting that as terrorist activities increase, such threats may become more common in commercial aviation. The model is intended to guide the creation of systems that help decision-makers effectively comprehend and respond to information attacks amidst the inherent noise of dynamic operational environments.
Key finding
Information attacks can effectively disrupt human decision-making by mimicking benign disruptions at various stages of information processing, leading to misinterpretation and failure to detect hostile events.
