이준규 ( Lee¸ Junkyu ) 한국외국어대학교 외국어교육연구소 2021 외국어교육연구 Vol.35 No.4

작업기억력과 같은 개인차 변인이 외국어교육에 미치는 영향은 상대적으로 덜 연구가 되어왔다. 개인차 변인의 중요성을 고려하여, 이 연구는 작업기억력의 영향력을 영어합성어의 의미합성을 통해 탐색하고자 한다. 영어모국어화자(L1) 집단과 고급수준의 영어학습자(L2) 집단이 실시간 의미 적합도 판단과제에 참여하였다. 이 과제에서 참여자들은 juice stone과 같이 영어에서 의미적으로 허용되지 않은 단어 연쇄를 가능한 한 빠르고 정확하게 판단하였다, 이러한 의미 차단과정의 정확도와 속도가 연산 폭 과업으로 측정된 작업기억력과 관련성이 있는지를 탐색하였다. 선형혼합모형 분석결과 L2집단의 정확도 점수는 작업기억력과 상관관계가 있는 것으로 나타났지만, 반응시간은 관련이 없는 것으로 나타났다. L1 집단에서는 정확도와 반응시간 모두 작업기억력과 관련성을 갖지 않았다. 외국어교육에서 개인차 변수에 대한 중요성에 대한 논의가 강조되었다. Despite the general consensus of the importance of individual difference in foreign language education, little is known the role of individual difference variables including working memory capacity. This study aims to examine the role of working memory capacity in sematic integrations of L2 compound comprehension. Along with an operation span task, L1 and L2 group participated in an online semantic acceptability task where the participants judged the acceptability of semantically ill-formed noun-noun compounds as quickly and accurately as possible. Three experimental conditions were manipulated by adding homonyms either to modifiers or to heads. Linear mixed effect regression revealed that the accuracy scores of L2 group in the experimental conditions were associated with the working memory scores; however, the response time were not correlated with the operations span measures. The importance of individual difference variables in foreign language education was highlighted.

RELATION PRIMING AND COMPOUND PROCESSING IN A SECOND LANGUAGE

JUNKYU LEE 사단법인 한국언어학회 2010 언어학 Vol.0 No.57

This study investigates online semantic integration patterns of second language (L2) speakers in processing familiar compounds in comparison with those of first language (L1) speakers. Particularly, adopting the Competition-Among-Relations-In-Nominals theory (Gagne & Shoben 1997, 2002) as a theoretical framework, this study examines whether L1 and L2 speakers demonstrate relation priming, in which previous exposure to a compound (e.g., tennis court) facilitates the processing of a subsequent compound (e.g., tennis shoes) which has the same first constituent and the same semantic relation. In an online lexical sense decision task, an L1 and an L2 group were asked to judge whether familiar compounds, operationalized as the existence in a large English corpus, had a sensible interpretation. Results revealed the effect of relation priming in both L1 and L2 group, indicating that a modifier in a compound plays a key role in online semantic integrations of two constituents in the compound. The finding also suggests that compound processing requires an obligatory process of selecting the interpretable relations between two nouns to establish a unified representation. An implication for the architecture of the lexicon was also discussed in relation to lexicalized and novel compounds.

Unaccusativity and Derivational Morphology in Second Language

Junkyu Lee 한국응용언어학회 2010 응용 언어학 Vol.26 No.2

This paper investigates second language (L2) learners’ knowledge of split intransitivity through derivational morphology, a rarely explored L2 empirical domain. Participants from three populations (advanced-ESL, high-advanced-ESL, and native-speakers of English) evaluated the acceptability of decontextualized words containing -er and re- affixes in English. The results revealed that, in the -er test, the high-advanced-ESL group behaved comparably to the NS group while, in the re- test, both the advanced-ESL and the high-advanced-ESL, groups differed significantly from the NS group. The asymmetrical findings were discussed in terms of the Unaccusative Trap Hypothesis (Oshita, 2001) and compositional differences of the two affixes. Also, the importance of researching the acquisition of the systematic nature of the L2 lexicon was highlighted, considering that not every facet of the lexicon is random, as was the case in this study.

Capital Mobility, Financial Risk, Institutions and Redistributive Spending

Junkyu Lee,Jeffrey B. Nugent 서울대학교 경제연구소 2004 Seoul journal of economics Vol.17 No.3

As democracy spreads, the importance of redistribution policies is believed to increase, bringing with them the threat of weakening incentives and slowing growth. Yet, to date the determinants of redistribution policies have rarely been investigated outside a few OECD countries and outside the context of narrowly defined transfer payments. This paper examines the determinants of a broader class of redistribution policies, namely, the share of public spending on health, education and welfare in total government spending in a larger set of countries (a panel data set consisting of 105 countries) over the period 1988-2000. In particular, the paper views redistributive spending as emanating from two global trends: deregulation of international capital movements and the spread of democratic institutions. Our basic hypothesis is that because of the risks involved in international capital mobility and the fact that their use of standard macroeconomic policies is increasingly limited by international rules of the game, governments find redistributive spending policies convenient tools for dealing with the distributive effects inherent in these risks, especially when financial crises actually occur. The results, with both fixed and random effects models, support most of the hypotheses, several of them quite strongly.

Ambiguity Advantage or Disadvantage? Lexical Access to Second Language Homonymy

Junkyu Lee(이준규) 한국영어학학회 2010 영어학연구 Vol.16 No.2

Recent first language (L1) psycholinguistic research (e.g., Rodd et al. 2002) has challenged a robust finding known as ambiguity advantage effect, in which words having multiple meanings are accessed faster than counterparts having a single meaning. This paper investigates whether second language (L2) learners shows the ambiguity advantage effect when comparing words having multiple meanings and few senses (e.g., bat) with words that have a single meaning and few senses (e.g., boy). In a visual lexical decision task, an L1 group and an L2 group showed opposite patterns in processing semantically ambiguous words. The L1 group processed ambiguous words slower than unambiguous words (i.e., ambiguity disadvantage effect) whereas the L2 group accessed ambiguous words faster than unambiguous words (i.e., ambiguity advantage effect). The findings are discussed in relation to the possible differences in the architecture of the L1 and the L2 mental lexicons.

Semantic Acceptability of Second Language Noun-noun Compounds and its Correlates with Linguistic Profiles

Junkyu Lee 한국영어학학회 2015 영어학연구 Vol.21 No.3

In psycholinguistics literature, a main divergence on noun-noun compounds such as orange juice is how the combinations of two nouns are mentally represented: full-listing models, full-paring models, and dual-route models. This study aims to address this representational issue by examining second language learners' offline semantic acceptability data while considering linguistic profiles of compounds (i.e., frequencies and the number senses of each constituents). L1 group and L2 group of an advanced level of English proficiency were asked to evaluate the semantic acceptability of 120 noun-noun compounds (60 well-formed and 60 ill-formed) on a 6-point scale. A multiple regression analysis revealed that the semantic acceptability by L1 group was positively correlated with the frequencies of compounds as a whole, which is in support of full-listing models. In contrast, a comparable statistical method for L2 group found that the semantic acceptability by L1 group was positively associated with the frequencies of compounds as a whole and are inversely with the number of senses of each constituent; and thus, the L2 data seem to lend a support for dual-route models

The Role of Head Nouns in Real-time Semantic Integration of Second Language Noun-noun Compounds

Junkyu Lee 한국영어학학회 2012 영어학연구 Vol.18 No.3

This study aims to investigate the role of head nouns during real-time interpretations of noun-noun compounds in English. A major debate in the first language (L1) psycholinguistics is which constituent (i.e., either a modifier or a head) plays more significant role in the online interpretation of noun-noun compounds. In the second language (L2) literature, this debate has been understudied. Implementing a priming method and focusing on a case where primes and targets share the second constituent, namely, the head noun, this study examines the facilitations of reaction times of the first and the second language speakers; an exposure to a noun-noun compound (e.g., orange tree) speeds up the interpretation of a subsequent compound (e.g., peach tree) when the two noun-noun compounds have the same thematic relation in comparison to a pair that have different thematic relation. On a computerized lexical sense decision task, L1 and L2 participants judged whether a series of compounds is sensible as quickly and accurately possible. Linear mixed-effect models revealed that the response patterns of the L1 and the L2 group did not differ significantly and both groups responded faster to the targets of the same relation than to those of the different relation. The findings were discussed with respect to the L1 debate on the real-time semantic integration and in terms of L2 compound processing.
