  • Recently, there are so many studies that herbal composition has the effect on enhancing the memorial ability. But there are few studies whether it has effect on enhancing attentional ability. The purpose of present study is to prove the effects of a herbal composition(ChongA 100) on enhancing not only memorial but also attentional ability. The memorial ability interfered by amyloid-${\beta}$ was evaluated with passive avoidance test Y-maze task. The attentional ability was studied with attentional set-shifting task(ASST). The 200mg/kg of ChongA100 could significantly recover the shortened latency of passive avoidance test and the interfered alternation of Y-maze task. The number of trials in ASST was significantly reduced as well. Our study suggests that it has effects on enhancing both memorial and attentional ability.

  • The purpose of this study was to investigate the differences between attentional networks according to sex and reflection-impulsivity in the cognitive styles of young children. The subjects of the study were 78 5-year-old children from the kindergarten or daycare center in Busan(with 40 in the reflection group, and 38 in the impulsivity group). The tests were conducted by using the Mating Familiar Test and the Attentional Network Test for young children. The study has used two independent t-tests to find out the differences between attentional networks according to sex, and reflection-impulsivity in the cognitive styles of young children. The results of this study were as follows. First, the boys with reflection cognitive style were significantly slower than the girls with the same style(t=2.18, p<.05). Second, young children with reflection cognitive style were significantly faster in the case of alerting effects than those with impulsivity cognitive style(t=-2.53, p<.05). The young children with reflection cognitive style were slower than those with impulsivity cognitive style in the case of orienting effect(t=2.04, p<.05). Children with a combination of both conflict effect and reflection cognitive style were significantly faster than those with impulsivity cognitive style(t=-2.89, p<.01). The results of the study suggested that there was a difference between attentional networks according to sex and reflection-impulsivity cognitive styles of young children.

  • 본 연구에서는 다양한 연령대의 운전자 집단(대학생, 중년 및 고령운전자)에 따라 주의능력 및 외부환경 적응능력에 대한 주관적 역량평가와 운전이동성 사이의 관련성에 차이가 있는지, 그리고 이러한 관련성이 운전자들의 동기특성에 따라 차별적으로 달라질 수 있는지 살펴보았다. 본 연구의 주요 결과를 요약하면 다음과 같다. 첫째, 운전자의 연령 증가에 따라 주관적 운전역량 평가 수준이 낮아지는 경향이 있었고, 특히 외부환경 적응능력에 대한 평가는 고령운전자 집단뿐만 아니라 중년운전자 집단에게서도 낮아질 수 있다는 것이 관찰되었다. 둘째, 주의능력에 대한 주관적 평가는 세 개의 운전자 집단 모두에서 운전이동성을 정적으로 예측하였으나 외부환경 적응능력은 고령운전자 집단에서만 이러한 관련성이 관찰되었다. 셋째, 대학생운전자 집단과 중년운전자 집단의 경우 두 가지 동기특성 중 접근동기만이 정적으로 운전이동성을 예측하였으나, 고령운전자 집단의 경우는 회피동기만이 부적으로 운전이동성을 예측하였다. 넷째, 중년운전자 집단의 경우에는 접근동기 수준이 높고 주의능력에 대한 주관적 평가가 높을수록 운전이동성이 증가하였으나, 고령운전자 집단의 경우는 회피동기 수준이 높고 자신의 외부환경 적응능력이 저하되어 있다고 평가할수록 운전이동성이 유의하게 낮아지는 경향이 관찰되었다. 이러한 결과는 운전자의 운전이 동성에 미치는 주관적 운전역량 평가와 동기특성의 효과가 운전자의 연령대별로 차별화될 수 있다는 것을 시사한다.

  • The current study explored how Korean-speaking children processed the multiple acoustic cues (VOT and f0) for the stop laryngeal contrast (/t'/, /t/, and /$t^h$/) and examined whether individual perceptual strategies could be related to a general cognitive ability performing executive functions (EF). 15 children (aged from 7 to 8) participated in the speech perception task identifying the three Korean laryngeal stops (3AFC) on listening to the auditory stimuli of C-/a/ with synthetically varying VOT and f0. They completed a series of EF tasks to measure working memory, inhibition, and cognitive shifting ability. The findings showed that children used the two cues in a highly correlated manner. While children utilized VOT consistently for the three laryngeal categories, their use of f0 was either reduced or enhanced depending on the phonetic categories. Importantly, the children's processing strategies of a f0 suppression for a tense-aspirated contrast were meaningfully associated with children's better cognitive abilities such as working memory, inhibition, and attentional shifting. As a preliminary experimental investigation, the current research demonstrated that listeners with inefficient processing strategies were poor at the EF skills, suggesting that cognitive skills might be responsible for developmental variations of processing sub-phonemic information for the linguistic contrast.

  • Objectives : Allergic children have known to have multiple behavior problems. Among them, attentional ability disorder is one of the most common problems. This study is to examine relationship between learning ability and allergic rhinitis by analyzing EEG status of children. Methods : We analyzed cognitive functions of two different children groups; 21 children with allergic rhinitis and 19 normal children with CANS 3000(Central & Autonomic Nervous System, LAXTHA Inc., Korea), cognitive functions assessment program by EEG. Results : 1. According to mean active EEG rhythm of Theta, Alpha, SMR, M-beta, there were no significant difference between allergic rhinitis and the normal group. 2. According to mean active EEG rhythm of right H-beta, Gamma wave allergic rhinitis group's value was significantly higher than that of the normal group. 3. According to mean cognitive strength, response, concentration, left / right brain activity and learning ability score, there were no significant difference between allergic rhinitis and the normal group. 4. According to mean workload score, allergic rhinitis group's value was significantly higher than that of the normal group. Conclusions : It is likely that allergic rhinitis group, which showed relatively high frequency EEG rhythm, is more fragile to stress and less active on mental processing. Along side with physical examination, psychological assessment should also be conjugated on treating children with allergic rhinitis.
