The UnCODE system: A neurocentric systems approach for classifying the goals and methods of Cognitive Warfare
Get PDFCognitive Warfare takes advantage of novel developments in technology and science to influence how target populations think and act. Establishing adequate defense against Cognitive Warfare requires examination of modus operandi to understand this emerging action space. This includes the goals and methods that can be realized through science and technology. Recent literature suggests that both human and nonhuman cognition should be considered as targets of Cognitive Warfare. There are currently no frameworks allowing for a unified way of conceptualizing short-term and long-term Cognitive Warfare goals and attack methods that are domain- and species-agnostic. There is a need for a framework developed through a bottom-up approach that is informed by neuroscientific principles to capture relevant aspects of cognition. The framework should be at a level of complexity that is actionable to decision-makers in war. In this paper, we attempt to cover the existing gap by proposing the Unplug, Corrupt, disOrganize, Diagnose, Enhance (UnCODE) system for classifying the goals and methods of Cognitive Warfare. The system is neurocentric by conceptualizing Cognitive Warfare goals from the perspective of how adversarial methods relate to neural information processing in an individual or society. The UnCODE system identifies five main classes of goals: 1) Eliminating a target’s ability to produce outputs, 2) degrading a target’s capacity to process inputs and produce outputs, 3) biasing a target’s input-output activity, 4) monitoring and understanding the input-output relationships in targets, and 5) enhancing a target’s capacity and ability to process inputs and produce outputs. Methods can be divided in two categories based on access to the target’s neural system: direct access and indirect access. The UnCODE system is domain- and species-agnostic and allows for interdisciplinary commensurability when communicating attack paths across domains. In sum, the UnCODE system is a unifying framework that captures that multiple methods can be used to reach the same Cognitive Warfare goals
A Multidimensional Cyber Defense Exercise: Emphasis on Emotional, Social, and Cognitive Aspects
Get PDFHands-on and practical learning has been key to cybersecurity education and training success. Cyber Defense Exercises (CDX) are a common approach to training, testing, and verifying technical and soft skills. However, full-scale CDX implementation is also an expensive training event. In order to advance such exercises to the next level, CDX organizers should further focus on educational, psychological, and cross-domain relationships. The paper discusses and proposes a multidimensional approach for CDX that balances cognitive, emotional, and social aspects critical for successful interdisciplinary learning. We share our experience incorporating knowledge from well-known psychology theories to CDX. We derive and describe seven elementary ingredients if a CDX is to meet the interdisciplinary and critical thinking needs of defensive cyberspace operations
An expandable voice user interface as lab assistant based on an improved version of Google’s speech recognition
Get PDFVoice assistants are potentially helpful when working in a scientific laboratory. A big challenge is the extremely specific use of language in every laboratory. As with any voice assistant, another concern
is data security. Here, we present Rainbow—an open source voice user interface (VUI) for scientific laboratories, that is adaptable to any Windows PC with Internet access. We used Google Translate Site (GTS) as a voice input and output system to ensure communication to the user. The scripting language AutoIt controls GTS, executes all actions and builds the VUI. Rainbow performs tasks from three different areas—general Microsoft Windows tasks, lab-specific tasks, and device-specific tasks. We achieved significantly higher speech recognition accuracy with our VUI than with GTS alone (91.3% versus 85.1%). Because of Rainbow’s architecture, it is possible to improve the voice assistant in terms of functionality and accuracy, allowing each laboratory to optimize its own Rainbow system in a user-friendly way. In a test setup, this led to a speech recognition accuracy of 98.6%. Taken together, Rainbow provides an opportunity for every scientist to implement highly specific scientific terms and tasks to this open source voice assistant system in a very user-friendly way

The Role of Trait and State Mindfulness in Cognitive Performance of Male Adolescents
Get PDFPurpose The number of mindfulness intervention projects is continually increasing. Within the educational environment, mindfulness has purported links to well-being, positive behaviour, educational and cognitive performance. Trait mindfulness is related to rational thinking and better performance in cognitive tests, suggesting that innate mindfulness ability contributes to self-regulation ability and thus the efficacy of mindfulness interventions. The current study investigates whether mindfulness is a moderating factor. It examines correlations between cognitive performance and trait mindfulness. The study investigates the influence of trait mindfulness on the ability of students to enter state mindfulness in an attempt to understand the role both types of mindfulness may have on cognitive performance. Participants and Method Two-hundred and five male students aged fifteen and sixteen completed the adolescent version of the Mindfulness Awareness Scale, the Cognitive Reflection Test, and the Toronto Mindfulness Scale. Results Hierarchical regression analysis found that state mindfulness was a predictor of cognitive reflection ability. ANOVA also found that having either trait or state mindfulness predicted higher cognitive reflection scores, but only state mindfulness had a significant effect on cognitive reflection. Trait mindfulness was not a moderating factor. Conclusion Both state and trait aspects of mindfulness ability influence cognitive performance. Those with higher trait mindfulness ability are better able to enter state mindfulness and thus had better cognitive reflection scores. However, where it is possible to induce state mindfulness into those with low trait mindfulness, CRT scores were also higher although not significantly so
A 3D mixed reality visualization of network topology and activity results in better dyadic cyber team communication and cyber situational awareness
Get PDFBackgroundCyber defense decision-making during cyber threat situations is based on human-to-human communication aiming to establish a shared cyber situational awareness. Previous studies suggested that communication inefficiencies were among the biggest problems facing security operation center teams. There is a need for tools that allow for more efficient communication of cyber threat information between individuals both in education and during cyber threat situations.MethodsIn the present study, we compared how the visual representation of network topology and traffic in 3D mixed reality vs. 2D affected team performance in a sample of cyber cadets (N = 22) cooperating in dyads. Performance outcomes included network topology recognition, cyber situational awareness, confidence in judgements, experienced communication demands, observed verbal communication, and forced choice decision-making. The study utilized network data from the NATO CCDCOE 2022 Locked Shields cyber defense exercise.ResultsWe found that participants using the 3D mixed reality visualization had better cyber situational awareness than participants in the 2D group. The 3D mixed reality group was generally more confident in their judgments except when performing worse than the 2D group on the topology recognition task (which favored the 2D condition). Participants in the 3D mixed reality group experienced less communication demands, and performed more verbal communication aimed at establishing a shared mental model and less communications discussing task resolution. Better communication was associated with better cyber situational awareness. There were no differences in decision-making between the groups. This could be due to cohort effects such as formal training or the modest sample size.ConclusionThis is the first study comparing the effect of 3D mixed reality and 2D visualizations of network topology on dyadic cyber team communication and cyber situational awareness. Using 3D mixed reality visualizations resulted in better cyber situational awareness and team communication. The experiment should be repeated in a larger and more diverse sample to determine its potential effect on decision-making
Nudging in der Kitaverpflegung
No full textDie Bedeutung der Verpflegung in Kindertageseinrichtungen hinsichtlich
der Prägung der Ernährungs- und Esskulturbildung steigt und ist
von zentraler Bedeutung für die Prävention von Übergewicht und ernährungsmitbedingten gesundheitlichen Folgen. Nudgingmaßnahmen
stellen ein effektives Instrument dar, eine gesundheitsförderliche Speisenauswahl zu unterstützen. Umfassende Empfehlungen für Nudgingmaßnahmen in Kindertageseinrichtungen fehlen bislang. Eine Analyse bestehender Nudges und deren Erweiterung im Setting Kita unter Berücksichtigung aller an der Kitaverpflegung beteiligten Akteure (Kita-Personal, Träger, Speisenanbieter) und einer einfachen Implementierbarkeit in den (Kita-)Alltag zeigt, dass sowohl speisenbezogene als auch umfeldbasierte Nudges die Speisenauswahl und -akzeptanz sowie die Verzehrmenge gesundheitsförderlicher Lebensmittel wie Obst und Gemüse positiv beeinflussen können. Im Weiteren weisen partizipative Ansätze sowie der Einbezug von Peers und des pädagogischen Personals großes Potenzial auf
