Children's knowledge of referential dependency involved in the interpretation of reflexives has been investigated mainly from a purely syntactic perspective. However, syntax alone is insufficient to account for various kinds of referential dependencies, as many of them require discourse interpretations. To fill this gap, the present study investigated the development of referential dependency established between the Mandarin reflexive ziji and its antecedent in preschool children by taking advantage of the properties of ziji, whose interpretations largely hinge on discourse contexts. A truth-value judgement task was conducted to investigate how 3- to 5-year-old Mandarin-speaking children build referential dependencies between the anaphor ziji and its antecedent and between the logophor ziji and its antecedent. The results show that children performed equally well in both types of referential dependencies, and they exhibit a developmental trajectory in their knowledge of referential dependencies. The implications of the findings were then discussed in relation to the role of processing factors and language-specific properties.

Unlike with the typically developing population, non-typically developing individuals, especially those with intellectual disabilities, have usually been recommended to learn and use only one language, despite perhaps coming from bilingual families or living in multilingual environments. This common practice, however, is not backed by empirical evidence; previous research, although limited, has systematically shown that bilingualism does not have negative effects. This study investigates how bilingualism shapes the executive control abilities of individuals with genetic disorders. Specifically, we compare the interference suppression abilities of Spanish-Catalan bilinguals and Spanish monolinguals with Prader-Willi syndrome. Fifteen participants with Prader-Willi syndrome were recruited in Spain. The bilingual group consisted of seven Spanish-Catalan bilinguals from Catalonia-an officially bilingual territory of Spain-, while the monolingual group was formed by eight Spanish speaking individuals from Madrid-an officially monolingual territory. Participants were administered two widely used psychological tasks: the Flanker Task (a non-language-based task) and the Stroop Task (a language-based task). Three experimental conditions were included in each task: neutral, congruent, and incongruent. Both accuracy and reaction time data were collected and analyzed. The results obtained are consistent between both tasks in showing (i) no detrimental effects of bilingualism; (ii) a high answer accuracy rate; (iii) a practice effect (the more familiar participants became with the tasks the faster their answers became); (iv) sensitivity to an interference effect (higher reaction times for incongruent trials than neutral trials) but not to a clear facilitation effect (lower reaction times for congruent trials than neutral trials). These results, far from being anecdotal, are in line with results from previous research investigating the effects of bilingualism among typically developing individuals as well as non-typically developing individuals with and without genetic disorders. This study not only evidences that Prader-Willi individuals can become bilingual if they are exposed to more than one language, but also that they can do so without showing negative effects at the cognitive level. In fact, taking into account the trend in the descriptive data, if an effect of bilingualism were in place, it would be a positive one. Bilingualism has repetitively been proven to neither be a burden nor to have negative effects for the typically or the non-typically developing population. Thus, as previous researchers have pointed out, there seems to be a clear incongruity between what the research is showing and the actual advice that these individuals and their families are receiving, and this should be amended without further delay.

This study examines the referential context effect on second-language relative clause ambiguity resolution by proficient L1 Chinese learners who learn English as a foreign language (EFL) and investigates whether the ambiguity resolution process is constrained by individuals' working memory capacity (WMC). It presents a self-paced reading study and investigates L2 relative clauses ambiguity resolution in two phases. The baseline phase probes Chinese EFL learners' initial attachment preference when comprehending global ambiguous sentences without referential context. In the further experimental phases, each target sentence is preceded by a referential context with either neutral or NP-biasing information. We observe the change in reaction time spent on processing sentences and answering comprehension questions. Results showed that firstly regardless of WMC, proficient Chinese EFL learners employed a high-attachment parsing strategy when there was no referential context. Secondly, referential context facilitated sentence processing and comprehension, as demonstrated by decreased reaction times in critical region and on comprehension questions from neutral to biased contexts, with no significant difference in accuracy rates. Notably, the contextual effect was more pronounced when high-attachment contextual cues were present. Thirdly, working memory capacity modulated the ambiguity resolution process. Participants with different WMCs showed different parsing behaviors, and this difference manifested itself in both the interpretive and post-interpretive stages of processing. Participants with lower WMC had limited cognitive resources for processing ambiguous sentences, whereas those with larger WMC were more adept at resolving ambiguity in a context-dependent manner. These findings offer new insights into L2 shallow sentence processing as well as WMC constraints in L2 ambiguity resolution.
