In an effort to investigate the effects of chatbots on English listening and reading skills, 46 college students participated in the current study. Participants consisted of first-year students who enrolled in an English class at a university in South Korea. They were randomly divided into two groups: one experimental group (n=24) and one control group (n=22). During 16 weeks, the experimental group engaged in chats with a chatbot, named Elbot, while the control group did not. There were pre- and post-tests to confirm the effects of the chatbot usage. Major findings are as follows: First, participants in both groups significantly improved listening and reading skills. On the post-listening test, however, the experimental group showed more improvements. Their listening proficiency level improved from intermediate to advanced level after engaging in chat with the chatbot. Limitations and implications for theory and practice are discussed at the end.

Objectives：Developmental reading disorder is a condition which manifests significant developmenttal delay in reading ability or persistent errors. About 3-7% of school-age children have this condition. The purpose of the present study was to validate the diagnostic values of Word/Nonword Reading Test and Letter-Symbol Discrimination Task for the purpose of overcoming the caveats of Basic Learning Skills Test. Methods：Sixty-three reading-disordered patients(mean age 10.48 years old) and sex, age-matched 77 normal children(mean age 10.33 years old) were selected by clinical evaluation and DSM-IV criteria. Reading I and II of Basic Learning Skills Test, Word/Nonword Reading Test, and Letter-Symbol Discrimination Task were carried out to them. Word/Nonword Reading Test：One hundred usual highfrequency words and one hundred meaningless nonwords were presented to the subjects within 1.2 and 2.4 seconds, respectively. Through these results, automatized phonological processing ability and conscious letter-sound matching ability were estimated. Letter-Symbol Discrimination Task：mirror image letters which reading-disordered patients are apt to confuse were used. Reliability, concurrent validity, construct validity, and discriminant validity tests were conducted. Results：Word/Nonword Reading Test：the reliability(alpha) was 0.96, and concurrent validity with Basic Learning Skills test was 0.94. The patients with developmental reading disorders differed significantly from normal children in Word/Nonword Reading Test performances. Through discriminant analysis, 83.0% of original cases were correctly classified by this test. Letter-Symbol Discrimination Task：the reliability(alpha) was 0.86, and concurrent validity with Basic Learning Skills test was 0.86. There were significant differences in scores between the patients and normal children. Factor analysis revealed that this test were composed of saccadic mirror image processing, global accuracy, mirror image processing deficit, static image processing, global vigilance deficit, and inattention-impulsivity factors. By discriminant analysis, 87.3% of the patients and normal children were correctly classified. Conclusion：The patients with developmental reading disorders had deficits in automatized visuallexical route, morpheme-phoneme conversion mechanism, and visual information processing. These deficits were reliably and validly evaluated by Word/Nonword Reading Test and Letter-Symbol Discrimination Task.

Objective : The purpose of this study was to investigate the effect of brain-timing training using an Interactive Metronome (IM) on the reading abilities of children with low brain-timing abilities. Methods : A single-group pretest and posttest (retrospective study) were conducted in 8 children whose timing abilities were lower than that for their age average and who were trained from 2019 to 2021. Brain-timing training was conducted 2 or 3 times per week, with 70 sessions in total and 40-50 minutes per session, depending on the developmental characteristics of the child. Changes in brain-timing ability before and after the training were measured using the IM Long-Form Assessment (LFA), and reading ability was measured using the Basic Academic Skills Assessment:Reading (BASA:R). Results : On the basis of the results of the brain-timing ability evaluation using the LFA, the reaction times of all the children during motor tasks were decreased, resulting in statistically significant improvements in their brain-timing abilities (p < .05). Moreover, the raw scores in the BASA:R reading and fill-in-the-blank tests were significantly improved (p < .05). Conclusion : This study is meaningful in that it presents a clinical basis for brain-timing training to improve the reading abilities of children.

The purpose of this study was to examine the relationship between children's information processing ability and basic learning abilities. To collect the data, two tests were given to 99 children. The Korean K-ABC(Moon & Byun, 1997) and Pictorial Basic Learning Abilities for Children(Kim, 2011) were used to examine the relationship between children's information processing and basic learning abilities. The collected data were analyzed by correlation analysis and multiple regression analysis. According to the results of this study, there was a significant positive correlation between information processing(sequential processing, simultaneous processing) and basic learning abilities including reading, writing, and basic mathematics. And information processing significantly affected basic learning abilities. Namely, simultaneous processing explained 22% of basic learning abilities and by adding sequential processing, the explanation was increased to 25%. In conclusion, the results of this study suggest various implications about children's basic learning abilities. These implications will help teachers and parents to understand their children's learning.

The visual span refers to the number of letters that can be accurately recognized without moving one's eyes. The size of the visual span is affected by sensory factors such as perimetric complexity, crowding, and mislocation of letters. Korean Hangul utilizes rather unique alphabetic-syllabary writing system, quite different from English and Chinese writing systems. Due to this combinatorial nature of the script, the visual span for Hangul characters can also be affected by the letter type (e.g., CV vs CVCC). The present study examined the effect of syllable complexity on the visual span for Hangul by comparing letter recognition accuracy across four letter type conditions (C only, CV, CVC, and CVCC). We also aimed to determine the meaningful letter type(s) that is associated with differences in reading abilities in Korean. Using a trigram presentation method, we found that overall recognition accuracy declined as syllable complexity increased. However, the visual span for CVC type was greater than that for CV type, suggesting that the effect is not necessarily linear, and that there might be other factors affecting the visual span for these types of letters. C and CV type showed fairly strong positive correlations with reading comprehension, suggesting that these might be the meaningful units for measuring visual span in relating to reading abilities.
