In this pre-registered kinematic-acoustic study, we test whether a foreign accent is present in the timing of co-speech manual movements. Results demonstrate a 'kinematic accent' in Dutch learners of Spanish producing Spanish cognates (e.g., Spanish <i>profe<b>SOR</b></i> - Dutch <i>pro<b>FES</b>sor</i>). Dutch learners time the maximum extension of their co-speech movements closer to the prominent syllable in their native Dutch (i.e., on <i>-fes</i>), even when acoustically emphasizing the correct Spanish syllable (<i>-sor</i>). Conversely, when incorrectly acoustically emphasizing the Dutch target (<i>-fes</i>), the maximum extension of their hand movement is attracted to the Spanish target syllable (<i>-sor</i>). This reveals competing timing processes between movement and vocalization systems for foreign language learners, demonstrating that not only your spoken accent but also your co-speech manual kinematics may give away your native language.</p>","PeriodicalId":32558,"journal":{"name":"Open Mind","volume":"10 ","pages":"66-78"},"PeriodicalIF":0.0,"publicationDate":"2026-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13053017/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147634323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We define and measure the simplicity and informativeness of a large number of logically possible modal systems, together with a sample of twenty-seven natural language inventories. We also consider a recently-introduced semantic universal for modal expressions in natural language, dubbed the Independence of Force and Flavor (IFF). Our analysis yields three main results: (i) every optimal modal system perfectly satisfies the IFF universal; (ii) as systems contain more IFF modals, they become more efficient; (iii) attested modal systems are more efficient than merely possible systems. These results indicate that general pressures for efficient communication can explain typological variation in the lexicalization of modality.</p>","PeriodicalId":32558,"journal":{"name":"Open Mind","volume":"10 ","pages":"1-28"},"PeriodicalIF":0.0,"publicationDate":"2026-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13053023/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147634217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For autonomous agents, these passive and flat architectures lack the cognitive organization necessary to model the dynamic and associative nature of long-term interaction. To address this, we propose Structured Episodic Event Memory (SEEM), a hierarchical framework that synergizes a graph memory layer for relational facts with a dynamic episodic memory layer for narrative progression. Grounded in cognitive frame theory, SEEM transforms interaction streams into structured Episodic Event Frames (EEFs) anchored by precise provenance pointers. Furthermore, we introduce an agentic associative fusion and Reverse Provenance Expansion (RPE) mechanism to reconstruct coherent narrative contexts from fragmented evidence. Experimental results on the LoCoMo and LongMemEval benchmarks demonstrate that SEEM significantly outperforms baselines, enabling agents to maintain superior narrative coherence and logical consistency.","PeriodicalId":32558,"journal":{"name":"Open Mind","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147903521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Across three experiments, we examine how individual German speakers use grammatical gender when producing plural forms of novel nouns.

It remains unclear whether this interference arises as part of routine dependency formation or as part of a repair mechanism that is activated when predictive dependency formation fails (e.g., Wagers et al., 2009). For example, it has been argued that reflexive anaphors resist attraction in comprehension because number/gender features of unpredictable elements are not associated with a strong 'prediction error' signal that might trigger retrieval-based and error-prone repair processes (Parker & Phillips, 2017). We test a version of the \"Error-driven Retrieval\" hypothesis by examining the interaction between reflexive attraction and the predictability of the anaphor. In two reading time experiments and one offline interpretation experiment, we find that the predictability of a reflexive dependency does not modulate its susceptibility to interference effects in comprehension. We propose that attraction is better captured as part of routine retrieval processes and that the (in)sensitivity of reflexives to structurally irrelevant distractors should be explained through other mechanisms.</p>","PeriodicalId":32558,"journal":{"name":"Open Mind","volume":"9 ","pages":"2031-2065"},"PeriodicalIF":0.0,"publicationDate":"2025-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12768552/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145913156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In two studies, we used distributional semantic word embeddings trained on corpora from different decades (HistWords) to capture meaning change at the level of the (English) language. We first compared these diachronic semantic spaces to the semantic spaces of individuals in different age cohorts (ranging from people in their 20s to people over 70) using an open dataset of associations norms (Small World of Words). Then, using HistWords, we sampled English words that have changed in meaning and words that have maintained the same meaning/usage patterns between the 1950s and the 1990s and collected relatedness judgments for those words with their nearest neighbors from each decade (1950s and 1990s) from both younger (18-33 years) and older (63-92 years) adults. Across the two studies, the semantic spaces of both older and younger adults were most strongly correlated with the semantic spaces derived from more recent corpora. We found little evidence of historical semantic spaces being differentially predictive of the semantic spaces of older adults relative to those of young adults.

Results showed that event remembering duration was close to the actual event duration for short events, but smaller for longer ones (i.e., temporal compression was not systematic but occurred selectively depending on event duration). Furthermore, events were mentally replayed more quickly when they were part of a sequence of several events than when they were presented alone, and this decrease in the duration of event recall with the number of events was more pronounced for longer events. Exploratory analyses revealed that individual differences in memory compression were predicted by visual imagery capacity.
