  • The study was designed to investigate implicit and explicit memory effec representations of bilinguals. Hierarchical model of bilingual information processing word naming and translation tasks in the context of semantically categorized or rar Experiments 1 and 2, bilinguals first viewed stimulus words and performed naming or tr then implicit and explicit memory tasks. In experiment I, word recognition times(exp were significantly faster for semantic category condition than random category condi naming task and lexical decision taskOmplicit memory task)showed no difference in e experiment 2, naming task and exlicit memory task showed categorization effect but fOWE a and implcit memory task showed no categorization effect. These findings support the which posits that memory representations of bilinguals are composed of two independer a and one common conceptual store.

  • The purpose of this study is to determine whether the mean fundamental frequency (F0) changes depending on language, task, or language proficiency for Korean-English bilinguals. A total of forty-eight Korean-English speakers (28 balanced bilinguals and 20 Korean dominant bilinguals) participated in the study. Participants were asked to read aloud two types of tasks in English and Korean. For statistical analyses, the language ${\times}$ task two-way repeated ANOVAs were conducted within the balanced bilingual group first, and then group ${\times}$ language two-way mixed ANOVAs. The results showed that the females in both bilingual groups changed their mean F0 depending on the language they used and the tasks (p<.05), whereas no significant results were found in the males in either group under any conditions. The mean fundamental frequency in the Korean reading task was significantly higher than that in the English reading task for females in both balanced and Korean dominant bilingual groups. Thus, changes in mean F0 depending on language and context may reflect gender-specific characteristics, and females seem to be more sensitive to the socio-cultural standards that are imposed on them.

  • Observation is one of the important aspects in science and science education. However. observation has so many varieties that the purpose and the meaning of scientific observations used in science education are different in persons, contexts, and subjects. In this study, we tried to understand the natures of scientific observation and investigated students' observational activities using four observation tasks: candle, double pendulum, iron filings around bar magnet, two electric bulbs connected in series. We required the subjects to observe the given tasks and described what did they observe. Based on students' observational descriptions, students' observational activities could be classified in four categories: primitive, interpretive, operational, and interfered observation. Also, we could find that some of the descriptions were non-observational activities such as predicting and questioning and so on. Finally, implications for the teaching of observation in science education are suggested.

  • 영어와 한국어의 통사구조의 차이로 인하여, 이중언어자와 비이중언어자인 한국 대학생의 영어 문장 유형에 따른 통사 처리에 있어 차이가 있을 것이다. 네가지 영어 문장 유형, 수동태, 관계사절, 물주구문, 가정법 구문 등으로 문장 완성 과제를 실험하여 이중언어자와 비이중언어자의 문장완성 시간과 오류율을 측정하였다. 실험 결과 비이중언어자인 한국 대학생은 다른 문장 유형에 비하여 물주구문에서의 통사처리 수행에 있어 이중언어자와 유의한 차이를 보였다. 이로부터 이중언어자와 한국 대학생의 영어 문장의 통사 정보처리의 자동화 및 어순효과 정보와 생물 주어(word animacy)구문 단서, 즉 대부분의 주어는 살아있는 사물의 명사로 이루어져 있다는 단서(Gass, l987)의 사용에 대하여 논의하였다.

  • Purpose: This study was to develop and verify the effects of the exercise-cognitive combined dual-task training program on cognitive function and depression of the elderly with mild cognitive impairment (MCI). Methods: A non-equivalent control group pretest-posttest design was used. The participants were assigned into two groups: an experimental group receiving an exercise-cognitive combined dual-task (n=20) and a control group receiving a simple-task (n=18). After 8 weeks of intervention (2 days per week), the change in depression and cognitive functions were compared between the groups. Results: General cognitive function (t=-2.81, p=.011), frontal cognitive function (Z=-3.50, p<.001), attention/working memory function (U=-2.91, p=.004), depression (t=4.96, p<.001) of the experimental group were significantly increased than those of the control group. Conclusion: The findings of the study showed that an exercise-cognitive combined dual-task program for MCI was effective in improving general cognitive function, frontal and executive function, attention/working memory function, and reducing depression.

  • Researchers have shown the negative compatibility effect (NCE) consistently using arrows. However, they provided inconsistent interpretations about the reason why the NCE happens. The purpose of the present study is to test the factors suggested to be critical for the NCE including automatic inhibition, updated information and top-down control. Presented with arrays of masked prime and targets composed of colored double-headed arrows, participants demonstrated invulnerable NCE on the basis of direction of arrows in the judgment of direction with corresponding hands (Experiment 1), with reverse-mapping hands (Experiment 2) and even in the color-judgment task (Experiment 3). These results imply that the main sources of NCE might be perceptual dominance and inherent properties of stimuli and responses; this contrasts with previously proposed explanations.

  • The study was designed to investigate implicit and explicit memory for words with processing theory.From experiment 1 to experiment 3,in a study phase,subjects first viewed stimulus words and were required to rate likeness of words of semantic processing task and to count lines of words of perceptual processing task.In a test phase,subjects were tested by implicit word completion task and explicit cued recall task.In experiment 1,levels of processing (LOP)effects were examined.Lop effects were obtained on the explicit memory tasks but not on the implicit memory tasks.In experiment 2,repertition of perceptual processing task influenced onlu implicit memory task.In experiment 3,bepertiotion of semantic processing task affected both implicit memory task and explicit memory task.These findings suggest that repetition effect of stimulus words are explanied better in dual process theory than transfer-appropriate processing theory.
