The languages individuals speak have been observed to influence how they perceive and interpret certain aspects of the world, but the conditions that give rise to these effects are not always clearly defined. One way to address the issue is to examine specific task contexts in which language is likely to modulate perception. Building on this, the aim of the present study was to investigate the role that native language (L1) plays in shaping motion processing in functional monolingual Turkish and English speakers (i.e., without intermediate or advanced proficiency in a second language) by using a supervised classification paradigm that involved sorting animated events based on either manner of motion or path. A total of 120 participants, including 60 native English speakers and 60 native Turkish speakers, were randomly assigned to one of the two conditions. The findings revealed a performance advantage for the English speakers in the manner-discrimination condition, in line with specific linguistic distinctions between the two languages. In contrast, overall performance was similar across the two groups when discrimination was based on path, a feature inherently expressed in both languages.

Understanding verbal irony involves detecting that the speaker’s intended meaning contrasts with the literal meaning. This is challenging for children as the underlying skills required to understand irony may not be fully developed. We investigated how 10-year-olds’ working memory, empathy skills, and gender were related to their processing and comprehension of written irony. Data from two previous eye-tracking experiments with 97 children (46 girls and 51 boys) were analysed. Results showed that children with stronger empathy skills had higher irony comprehension accuracy and were less likely to reread ironic phrases. Higher working memory was linked to faster processing of irony but did not lead to higher comprehension. Conversely, lower working memory was associated with more accurate irony comprehension. Child gender was not related to irony comprehension. These results imply that working memory and emotional perspective-taking are important for children’s irony comprehension, underscoring theories that take individual differences into account.

The connection between working memory (WM) and the breadth of vocabulary knowledge (BVK) in foreign language young learners remains underexplored, particularly with respect to how these constructs co-develop across the primary school years. Although growth in WM has been linked to early gains in BVK, the directionality and temporal dynamics of their association are not well understood. Utilizing a cross-lagged panel design, this study tracked the development of WM and BVK in 158 young learners from grade 1 to grade 5. Results unveiled lagged associations between WM and BVK, suggesting that working memory serves as a valuable indicator for future BVK acquisition, while also indicating that accumulated BVK may, in turn, exert an influence on WM. These findings highlight a complex, bi-directional relationship between WM and BVK throughout primary school students’ formative years, in line with the transactional model.

Object relatives (ORs) have been reported to cause heavier processing loads than subject relatives (SRs) in both pre- and postnominal position (prenominal relatives: Miyamoto & Nakamura 2003, Kwon 2008, Ueno & Garnsey 2008; postnominal relatives: King & Just 1991, King & Kutas 1995, Traxler et al. 2002). In this article, we report the results of two eye-tracking studies of Korean prenominal relative clauses that confirm a processing advantage for subject relatives both with and without supporting context. These results are shown to be compatible with accounts involving the accessibility hierarchy (Keenan & Comrie 1977), phrase-structural complexity (O'Grady 1997), and probabilistic structural disambiguation (Mitchell et al. 1995, Hale 2006), partially compatible with similarity-based interference (Gordon et al. 2001), but incompatible with linear/temporal analyses of filler-gap dependencies (Gibson 1998, 2000, Lewis & Vasishth 2005, Lewis et al. 2006).

The source of syntactic island effects has been a topic of considerable debate within linguistics and psycholinguistics. Explanations fall into three basic categories: grammatical theories, which posit specific grammatical constraints that exclude extraction from islands; grounded theories, which posit grammaticized constraints that have arisen to adapt to constraints on learning or parsing; and reductionist theories, which analyze island effects as emergent consequences of non-grammatical constraints on the sentence parser, such as limited processing resources. In this article we present two studies designed to test a fundamental prediction of one of the most prominent reductionist theories: that the strength of island effects should vary across speakers as a function of individual differences in processing resources. We tested over three hundred native speakers of English on four different island-effect types (whether, complex NP, subject, and adjunct islands) using two different acceptability rating tasks (seven-point scale and magnitude estimation) and two different measures of working-memory capacity (serial recall and n-back). We find no evidence of a relationship between working-memory capacity and island effects using a variety of statistical analysis techniques, including resampling simulations. These results suggest that island effects are more likely to be due to grammatical constraints or grounded grammaticized constraints than to limited processing resources.

This article is a crosslinguistic investigation of the hypothesis that the average information rate conveyed during speech communication results from a trade-off between average information density and speech rate. The study, based on seven languages, shows a negative correlation between density and rate, indicating the existence of several encoding strategies. However, these strategies do not necessarily lead to a constant information rate. These results are further investigated in relation to the notion of syllabic complexity.

Sprouse, Wagers, and Phillips (2012) carried out two experiments in which they measured individual differences in memory to test processing accounts of island effects. They found that these individual differences failed to predict the magnitude of island effects, and they construe these findings as counterevidence to processing-based accounts of island effects. Here, we take up several problems with their methods, their findings, and their conclusions.

First, the arguments against processing accounts are based on null results using tasks that may be ineffective or inappropriate measures of working memory (the n-back and serial-recall tasks). The authors provide no evidence that these two measures predict judgments for other constructions that are difficult to process and yet are clearly grammatical. They assume that other measures of working memory would have yielded the same result, but provide no justification that they should. We further show that whether a working-memory measure relates to judgments of grammatical, hard-to-process sentences depends on how difficult the sentences are. In this light, the stimuli used by the authors present processing difficulties other than the island violations under investigation and may have been particularly hard to process. Second, the Sprouse et al. results are statistically in line with the hypothesis that island sensitivity varies with working memory. Three out of the four island types in their experiment 1 show a significant relation between memory scores and island sensitivity, but the authors discount these findings on the grounds that the variance accounted for is too small to have much import. This interpretation, however, runs counter to standard practices in linguistics, psycholinguistics, and psychology.

Simultaneous interpreting (SI), a challenging task enabled by bilingualism, is claimed to distinctly tax working memory (WM). However, causal designs are missing, limiting our understanding of the phenomenon. We recruited 50 Chinese-English bilinguals and assessed their WM performance (alongside inhibitory and fluency outcomes) before and after L1–L2 SI or a control task (text comprehension). WM scores (especially under high-demand, multimodal conditions) increased after text comprehension but not after SI, adjusting for age of L2 appropriation, years of L2 use, L2 proficiency and SI competence. Of note, WM was assessed immediately before and after SI, ruling out other cognitive influences. Conversely, no distinct patterns were observed on inhibitory or fluency tasks. Briefly, this activity seems to hinder practice-related WM gains – a finding that expands contemporary accounts of interpreting.
