Item Structure transfer and consolidation in visual implicit learning(2025-09-16)Transfer learning, the re-application of previously learned higher-level regularities to novel input, is a key challenge in cognition. While previous empirical studies investigated human transfer learning in supervised or reinforcement learning for explicit knowledge, it is unknown whether such transfer occurs during naturally more common implicit and unsupervised learning and, if so, how it is related to memory consolidation. We compared the transfer of newly acquired explicit and implicit abstract knowledge during unsupervised learning by extending a visual statistical learning paradigm to a transfer learning context. We found transfer during unsupervised learning, but with important differences depending on the explicitness/implicitness of the acquired knowledge. Observers acquiring explicit knowledge during initial learning could transfer the learned structures immediately. In contrast, observers with the same amount but implicit knowledge showed the opposite effect, a structural interference during transfer. However, with sleep between the learning phases, implicit observers, while still remaining implicit, switched their behavior and showed the same pattern of transfer as explicit observers did. This effect was specific to sleep and not found after non-sleep consolidation. Our results highlight similarities and differences between explicit and implicit learning while acquiring generalizable higher-level knowledge and relying on consolidation for restructuring internal representations.Item The public opinion effects of antisemitic elite cues:a survey experiment on the Hungarian Soros campaign(2025-10-06)Right-wing populist leaders have long vilified left-wing activist George Soros to justify their policies. They accuse Soros and his organisations of being globalist elites who attack national sovereignty and traditional family values. The accusations themselves are loaded with antisemitic tropes. Despite this, it is unclear whether these populist, anti-elite messages effectively persuade citizens, or if antisemitic appeals specifically drive their impact. To answer these questions, we conduct a survey experiment in Hungary mimicking the Hungarian government's propaganda, which sometimes uses Soros as a symbol to mobilise support. We show that a random Soros' endorsement reduced policy support among pro-government respondents but increased it among anti-government ones. This suggests that Soros-bashing serves as a partisan cue in populist communication, helping to shape constituent preferences. However, overt antisemitic priming did not amplify the effects of Soros cues on policy preferences. These findings highlight the potential and limits of populist elite cueing.Item Medical Geneticists’ Interpretations of Genetic Disorders in Roma Communities in Post-Socialist Hungary(2025-09-01)The article investigates the utilization of ethnic classification by human geneticists in Hungary, with a particular focus on the Roma minority. Drawing on qualitative expert-interviews, it analyzes how historically situated social imaginaries inform the production of genetic knowledge. The study explores how human genetics constructs heritable disorders as ethnic diseases, exposing the epistemological and ethical tensions inherent in translating sociocultural difference into biological terms.Item Geopolitikk og sikkerhetsledelse(2025-03-12)Geopolitical and geo-economic conflicts generate significant political risk for business as well as the public and voluntary sectors. This leads to a growing need for good security management. The articles in this special issue address the development of geopolitical risk and changes in war and conflict. The articles contribute to increased knowledge about geopolitical risk assessment and management.Item Geopolitikk, politisk risiko og ledelse(2025-03-12)The geopolitical context in which Norwegian industry operates is changing rapidly. It is characterized by a multitude of hostile actors and new types of conflict. Security is now about much more than military threats to the state. The political, economic and financial dimensions of security are just as important. Security means financial security, energy supply, critical infrastructure, social security, and corporate security. The spectrum of conflict ranges from conventional war to influence operations, cyber-attacks and hybrid warfare. A number of non-state actors, with and without state support generate a broad range of risks. Technological development means that even small groups can cause great damage. It is often difficult to identify who is behind that attack, and to distinguish random events from malicious attacks before it is too late. This article deals with trends in international politics and the transition from a liberal international world characterized by globalization to a more uncertain and geopolitical world. It discusses the new threats that Norwegian business and industry face, and what this means for political risk and corporate security management. In order to secure continuity in operations, companies have to establish structures and procedures for risk analysis, crisis management and business continuity, and develop a security culture in the organization. It is the management’s responsibility to ensure that corporate security and risk management is integral part of operations.
