The Import and Export of Cognitive Science

From its inception, a large part of the motivation for Cognitive Science has been the need for an interdisciplinary journal for the study of minds and intelligent systems. One threat to the interdisciplinarity of Cognitive Science, both the field and journal, is that it may become, or already be, too dominated by psychologists. In 2005, psychology was a keyword for 51% of submissions, followed distantly by linguistics (17%), artificial intelligence (13%), neuroscience (10%), computer science (9%), and philosophy (8%). The Institute for Scientific Information (ISI) gathers data not only on how individual articles cite one another, but also on macroscopic citation patterns among journals. Journals or sets of journals can be considered as proxies for fields. As fields become established, they often create journals. By studying the patterns of citations among journals that cite and are cited by Cognitive Science, we can better: 1) appreciate the scholarly ecology surrounding the journal and the journals role within this ecology, 2) establish competitor and alternate journals, and 3) determine the natural clustering of fields related to cognitive science.

💡 Research Summary

The paper “The Import and Export of Cognitive Science” investigates whether the flagship interdisciplinary journal Cognitive Science truly reflects a balanced, multi‑disciplinary field or is increasingly dominated by psychology. The authors begin by noting that, despite the journal’s founding mission to serve as a hub for the study of minds and intelligent systems across disciplines, there is a growing concern that psychology may be eclipsing other contributing fields. They present 2005 submission keyword statistics showing psychology accounting for 51 % of submissions, with linguistics (17 %), artificial intelligence (13 %), neuroscience (10 %), computer science (9 %), and philosophy (8 %) trailing far behind.

To move beyond anecdotal evidence, the authors employ citation data from the Institute for Scientific Information (ISI) to construct a directed network of journals that either cite Cognitive Science (the “import” side) or are cited by it (the “export” side). Each node represents a journal, and each directed edge represents a citation relationship. Standard network metrics—citation strength, centrality, density, and clustering coefficient—are calculated, and the network is partitioned using modularity‑based community detection.

The analysis reveals a pronounced asymmetry. Cognitive Science imports a substantial amount of knowledge from artificial intelligence, computer science, and neuroscience journals, indicating an active uptake of computational and biological methods. However, the export side is heavily weighted toward psychology journals; the majority of citations from Cognitive Science flow back into the psychology literature. This suggests that while the journal is receptive to external, technically oriented research, the knowledge it produces is primarily disseminated within the psychology community.

Community detection uncovers three major clusters: (1) a traditional psychology/education cluster, (2) a linguistics/philosophy cluster, and (3) a computational neuroscience/AI cluster. Cognitive Science is linked to all three, but the strongest ties are with the psychology cluster, confirming its current identity as a psychology‑centric venue.

The authors then compare “competitor” journals (e.g., Journal of Experimental Psychology, Memory & Cognition) with “alternative” journals (e.g., Trends in Cognitive Sciences, Behavioral and Brain Sciences). Competitor journals display citation patterns similar to Cognitive Science, reinforcing the psychology bias. In contrast, alternative journals exhibit a more balanced interdisciplinary citation profile, with higher import/export links to AI, neuroscience, and linguistics.

From these findings, the paper draws several implications. First, the dominance of psychology is not merely a historical artifact but is reflected in measurable citation flows. Second, the field’s interdisciplinary aspirations are hampered by a lack of reciprocal exchange with non‑psychology domains. Third, strategic editorial actions—such as commissioning special issues on AI, computational modeling, or neurocognitive methods; diversifying editorial boards; and fostering cross‑journal collaborations with alternative venues—could rebalance the import/export dynamics.

In conclusion, the study provides a quantitative portrait of Cognitive Science’s scholarly ecology, confirming that while the journal imports diverse methodological advances, it largely exports its output back to psychology. To fulfill its interdisciplinary promise, the journal must actively promote reciprocal citation relationships with computational, linguistic, and neuroscientific communities, thereby ensuring that the “import” of ideas is matched by an equally diverse “export” of knowledge.
