L2 Prediction Guided by Linguistic Experience

천은진 한국영어교육학회 2020 ENGLISH TEACHING(영어교육) Vol.75 No.-

Research suggests that prediction is important for language comprehension and learning. Accordingly, it becomes crucial to understand factors that can influence prediction. In this regard, speakers’ prior linguistic experience such as parsing bias has been claimed to affect prediction in the error-based learning account. To test this claim, the current study, using the visual world eye-tracking paradigm, investigated if L2 speakers’ anticipatory eye movements are influenced by their parsing bias, and if individuals’ parsing bias interacts with their working memory capacity and/or vocabulary size for the prediction. The results showed no main effect of the parsing bias on the prediction overall, and the parsing bias did not interact with the working memory capacity and/or the vocabulary size for the prediction. Importantly, however, the speakers’ parsing bias significantly interacted with the trials. The influence of the parsing bias over the course of this experiment suggests that L2 speakers’ prediction is guided by their recent experience with linguistic input as well as long-term linguistic experience.

Objectives: The objective of this study was to compare psychological characteristics, such as temperament, character, defense style and personality of major depressive disorder (MDD) to trauma and stress related disorder (TSRD). Methods: The study used a total of 140 patients, divided into two groups (69 MDD, 71 TSRD). These data was obtained from a database of patients who had visited a Yeungnam University Hospital’s psychiatric department from January 2011 to December 2017. Levels of stress were rated based on the Korean version of the Social Readjustment Rating Scale. Psychological characteristics between the two groups were compared using the Temperament and Character Inventory (TCI), the Defense Style Questionnaire (DSQ), and the Personality Disorder Questionnaire-4+ (PDQ-4+). Also, a hierarchical multiple regression analysis was conducted to investigate the effects of temperament, character, and defense mechanisms on severity of depression. Results: No significant difference was noticed in demographic characteristics and the level of stress between the two groups. The patients with MDD recorded higher scores in Beck Depression Inventory (BDI) (t=3.092, p<0.05) and Beck Anxiety Inventory (BAI) (t=2.473, p<0.05) than the patients with TSRD. The MDD patients also exhibited higher harm avoidance (p<0.012) but lower self-directness (p<0.002) scores. The MDD patients used maladaptive defense style (p<0.049) more frequently than trauma and related disorder patients. The MDD patients also recorded higher scores on schizoid (p<0.001), borderline (p<0.001), avoidant (p<0.016) personality disorders. Hierarchical multiple regression analysis and path analysis showed that defense mechanism interrelates with temperament and personality traits and significantly affected the severity of depression. Conclusion: These findings would be useful in understanding MDD patients. Various psychotherapies can improve the defense mechanisms of depressed patients and help manage depression.

Objectives:The purpose of this study was to examine the relationships of anxiety& depressive symptoms according to the severity of alcohol use in patients with alcohol use disorder. Methods:A total of 85 patients with alcohol use disorders were enrolled in this study. The severity of alcohol use was measured by the Korean version of alcohol use disorders identification test(AUDIT-K)& National Alcohol Screening test(NAST). Anxiety and depressive symptoms were measured by using the Beck Anxiety Inventory(BAI) and the Beck Depression Inventory(BDI), respectively. Pearson’s correlation test was applied to correlate among the severity of alcohol use, anxiety and depressive symptoms. Results:The mean scores of AUDIT-K, NAST, BAI and BDI were 22.22(±8.28), 6.24(±3.25), 18.64(±13.08), and 22.05(±10.13), respectively. Pearson’s correlation test showed that between the score of AUDIT-K and NAST, BAI or BDI, there were positively significant correlations(r=.534, p<.01 r=.231, p<.05 r=.334, p<.01), respectively. And in cases of≥26 score of AUDIT-K, there were much more positive correlations with BAI(r=.425, p<.05). Conclusion:The results of this study demonstrated that patients with alcohol use disorders have high co-morbid anxiety and depressive disorders. Overall, the greater severity of alcohol use may be associated with more anxiety and depressive symptoms. However, it is suggested that in the patients with severe alcohol use, correlation appeared to be positive only for anxiety symptoms.

To investigate psychopathoIogy and executive functions of attention deficit hyperactivity disorder (ADHD) children according to intelligence level, this study included 197 ADHD children who visited the outpatient department of neuropsychiatry of YeungNam University Medical Center, from July 2000 to June 2002. The children were divided into groups based on their intelligence levels. They were compared by the Personality Inventory for Children (PIC), Conncers' Continuous Performence Test (CPT), and Wisconsin Card Sorting Test (WCST). There were significant differences in PIC, on the subscales of verbal development, socialization and autism. In the CPT, there was no significant difference. In the WCST, there were significant differences in the total number of errors, the number of perseverative errors, the number of completed categories and the number of trials needed to complete the first category. Considering these results, the intelligence level of ADHD children is related to their disabilities and behavioral symptoms.Executive functions such as abstract thinking, categorization, working memory and flexibility had significant relationship to the intelligence levels of ADHD children. Therefore, the intelligence level of children with ADHD influences the higher executive functions of regulating attention and information processing rather than attentional functions and capacity alone.

Electroencephalography is the most practical and accessible neuroimaging technique. An abnormal pattern of asymmetric activity in the frontal regions due to relative hyperactivity over the right and/or relative hypoactivity over the left frontal regions has been demonstrated in the electroencephalographic studies of depression. Alterations in brain functional cortical connectivity in resting-state networks and a loss of selectivity in resting functional connectivity were detected in an electroencephalographic study of major depressive disorder. Researchers suggested that several electroencephalography-based methods may be useful biological marker for predicting antidepressant response. Alpha- and theta-band EEG abnormalities, the combined Antidepressant Response Index(ATR), cordance, EEG source localization have the potential to offer predictors of treatment response. Future studies will be needed to validate their usefulness for clinical practice.

EEG biofeedback or neurofeedback is a promising tool for treating dysregulation of central nervous system. But evidence for its benefit in adult psychiatric patient is supported largely by case reports and uncontrolled studies. In this article author reviewed current studies of neurofeedback treatment in depressive and anxiety disorders. Additionally, recent progress has been made in understanding neural mechanism of neurofeedback, such as up-regulation of functional connectivity and induction of microstructural changes of gray and white matter. Integrated EEG and real time functional MRI imaging allows users to self-control electrical and hemodynamic activities of brain simultaneously.

자살의 생물학적 기전

Suicide is a behavior that is intended to cause death by itself and requires medical treatment, resulting in suicidal attempt or completion. Suicide causes loss of life, damages the body, costs a lot of medical expenses, and causes families to fall into sorrow and suffering therefore this suicide is a huge loss to family and society. There have been attempts to reduce and prevent suicide by understanding the mechanism of suicide. The mechanism of suicide can be thought of as psychological mechanism and biological mechanism. In the past, if we considered the psychological and biological mechanisms separately, the development of neuroscience now connects and integrates these two. Psychological factors affect biological factors and biological temperaments also affect perception or thinking about the situation and increase psychological vulnerability. Distant factors in suicidal behavior-such as childhood adversity and family and genetic predisposition-increase the lifetime risk of suicide. They alter the response to stress and other processes through changes in gene expression and regulation of emotional and behavioral characteristics. Distant factors affect the biological system and consequently changes in these systems can increase the risk of suicide. In other words, the distal factor does not directly induce suicidal behavior but rather acts indirectly through developmental or mediating factors. These mediating factors are impulsive aggressive and anxious trait, and chronic use of substances. The mechanism of this disorder is the abnormality of the serotonin system and the abnormality of the lipid level. Proximal factors are associated with the onset of suicide events and include changes in the major neurotransmitter systems, inflammatory changes, and dysfunction of glial cells in the brain. A series of studies, including a variety of research methods and postmortem and in-vivo imaging studies, show the impairment of the serotonergic neurotransmitter system and hypothalamic-pituitary-adrenal axis stress response system for suicidal behavior. These disorders lead to suicidal behavior due to difficulty in cognitive control of mood, pessimism, reactive aggression, abnormality in problem solving abilities, excessive response to negative social signals, severe emotional distress, and cognitive dysregulation of suicidal ideation.

Objectives: There are several studies about the prevalence of comorbid personality in the patients with panic disorder, and the comparison of defense mechanisms between patients with panic disorder and those with normal controls. The purpose of this study is to investigate specific factors of personality and defense mechanisms that affect symptoms in panic disorder patients. Methods: We recruited 38 patients with panic disorder according to the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorder, 4th edition. We investigated specific factors of personality and defense mechanisms affecting symptoms in the patients using the Symptom Checklist-90-Revised (SCL-90-R), the Personality Disorder Questionnaire-4+,and the Defense Style Questionnaire. Results: The defense style turned out to be more primitive as the positive symptom distress level of SCL-90R increased. The factors of personality affecting panic disorder were dependence, avoidance, degree of depress and negativistic personality, while the factors of defense mechanism that influence symptoms of panic disorder were maladaptive defense style, acting out and somatization. In contrast, the symptomatic factor of panic disorder that affects maladaptive defense style was interpersonal sensitivity of SCL-90R. Conclusion: The finding suggests that the level of maturity in defense mechanism is negatively correlated with the severity of symptoms in panic disorder. Interpersonal themes, such as dependence and avoidant personality, can worsen the symptoms of panic disorder.
