This study examines how words are associated in adolescents with depressive symptoms. For the main purpose of this paper two research questions were raised. The first question was whether and how a depressive disorder would be related to the words associated when being primed by a school-related stimulus item. The second question was whether age and gender would be related. In an attempt to respond to these two major concerns, a word association task was administered. Results showed that there was a similar ranking pattern in the most frequent words produced by all three groups of participants: the typical, potential, and risky groups. By contrast, the frequency ratios of a particular set of associated words were different at a statistically significant level across the three groups. As regards these main findings, this study proposed that a semantic relationship, a semantic network, and semantics of emotional words should be taken into consideration in interpreting the words associated most frequently in response to school-related stimuli in adolescents with depressive symptoms.

This study investigated Korean heritage speakers' phonological knowledge compared with L2 learners and native controls. The results of a picture-word discrimination task using three alveolar stop sounds /t/, /th/ and /t'/ in Korean revealed radical differences between heritage speakers and L2 learners compared with native controls: heritage speakers' phonemic sensitivity to distinguish the three stop sounds was as robust as native speakers' even at the early stages of general oral proficiency whereas L2 learners' increased steadily as their general oral proficiency improved. In addition, heritage speakers' high performance was consistent regardless of conditions (e.g., tal for the image of 'the moon' in Match condition vs. thal or ttal in Mismatch condition) whereas L2 learners showed significantly lower accuracy rates in Mismatch condition, indicating they failed in rejecting mismatched stop sounds. Based on the results, we suggest that adult acquisition of phonology in heritage language is a process of retrieving and strengthening old phonological memories, which is different from encoding new sound memories in the case of typical adult second language learning.

It has been subject to debate regarding whether the increase of length of residence (LOR) in a second language (L2) community can facilitate the acquisition of L2 sounds or not (Flege & Fletcher, 1992; Jia et al., 2006). To shed further light on this issue, this study examined 34 Chinese speakers' acquisition of L2-English /I/-/i/ over 5 years, during which the participants varied in LORs in England. Their perception and production of /I/-/i/ were repeatedly tested with AXB discrimination tasks and read-aloud tasks in 2012 (Test1), 2013 (Test2), 2014 (Test3) and 2017 (Test4). After-test questions were asked to collect information on daily language use during the intervals of two tests. It was found that the participants' perception performance significantly improved during the first year of arrival but “fossilized” from then on. LOR was found to have played a significant effect on their perceptual improvement in Test2 but not in Test3 and Test4. However, findings from the production tests indicated that the “intensive” exposure to native English input during the first year of arrival did not significantly benefit participants' accuracies in producing /I/ in general; LOR was non-significant on their production of /I/ in any of the four tests. Overall, LOR was found to have significantly benefited participants' perception but not production at the first year of arrival, while it did not play a significant effect on perception or production from then on. Findings from the after-test questions suggested that LOR alone can hardly facilitate the acquisition of L2 sounds. Particularly, as hypothesized by SLM-r, the perceived L1-L2 distance and the quantity/quality of L2 input during the period of staying in an L2-speaking community are critical for the success of L2 sounds acquisition (Flege et al., 2021).

Given the number of bilingual individuals worldwide, many of patients with Alzheimer's disease (AD) or Parkinson's disease (PD) are bilinguals. Yet little is known about the consequences of the two neurodegenerative diseases on the language of bilingual patients. In this paper, we review the available data in the bilingual literature, specifically the decline of language in patients with AD and PD at the lexical and grammatical levels. Our literature search of three electronic databases identified nine articles on bilingual patients with AD and five on those with PD that analyzed the lexicon and grammar of these patients. The findings of these studies are inconsistent but suggest that AD and PD should affect both languages in bilingual patients. They also show a trend that AD results in greater difficulties with lexicon and L2 grammar, while PD affects L1 grammar to a greater extent. This pattern is as expected by the declarative/procedural model that each disease affects a distinct memory system.
