In the digital era of academic communication, scholarly visibility has shifted, positioning journal covers as the primary visual gateway for research attention. This study introduces the concept of "academic significance foregrounding, " defined as the mechanism by which journal covers, through the integrated arrangement of imagery, layout, and indicative text, visually communicate the importance and thematic focus of research prior to formal reading, thereby influencing attention allocation. Taking Nature covers as a case study, this research traces the visual evolution of covers from informational bulletin boards (1869) to contemporary attention interfaces, revealing how covers have transformed from passive publication identifiers into active communication tools embedded within editorial governance structures. The study constructs the Visual Communication Impact Transmission (VCIT) model, which operationalizes the cover effect transmission process into four progressive levels: the visual synergistic configuration layer (design input), where scientific discoveries are transformed into brand-recognizable visual signals through institutionalized selection, conceptual translation, and multimodal coordination; the attention capture and semantic anchoring layer (cognitive processing), where visual salience captures reader attention while indicative text anchors semantic interpretation for precise meaning delivery; the academic diffusion and impact transmission layer (communication behavior), where attention advantages convert into reading and citation behaviors, with academic quality serving as a critical moderating variable; and the academic significance foregrounding and capital accumulation layer (outcome effects), where early visibility advantages consolidate into symbolic, social, and institutional capital. Empirical evidence from scientometric studies supports the model's core proposition that cover effects primarily manifest as "visibility acceleration" rather than "quality substitution"—covers do not alter the long-term logic of academic evaluation but influence when research enters academic attention. Analysis reveals that Nature's cover mechanism operates through three interconnected dimensions: institutionalized selection mechanisms providing organizational foundations for foregrounding decisions, conceptual translation strategies enabling visual expression of complex scientific concepts, and multimodal coordination frameworks integrating images, text, and layout systems to achieve functional complementarity. For Chinese English-language scientific journals, the study identifies the key gaps as lying not in visual aesthetics but in institutional embeddedness and organizational integration. The research proposes a tiered optimization pathway: cognitive upgrading and functional positioning at the foundational level; process standardization and institutional development for journals with basic editorial capacity; organizational development and resource allocation for mature publishing institutions; and aesthetic refinement and style exploration only after institutional mechanisms are established. Covers function as visibility accelerators—not quality substitutes—and their effectiveness depends on sustained academic quality. This research provides a theoretical framework for understanding the mechanistic role of visual design in academic communication and offers analytical references for Chinese journals to achieve synergistic improvement of visual translation capabilities and publication governance in their internationalization process.
