The purpose of the present study was to investigate the responses to positive/negative emotional stimuli for the different sensitivities of behavioral activation system (BAS) and behavioral inhibition system (BIS). We recorded If-channel EEG data for 8 BAS sensitive subjects an48 BIS sensitive subjects. EEGs were analyzed with LORETA (Low-resolution electromagnetic tomography) From scalp-recorded electrical potential distribution, LORETA computes the three-dimensional intracerebral distributions of current density for specified EEG frequency bands. hs results , significant differences between the BAS sensitive group ant the BIS sensitive group appeared LORETA alpha activities over the prefrontal lobe and the cingulate gyrus. Prefrontal regions and limbic system including cingulate gyrus are involved in emotional processing. Moreover, subjects with the high BAS sensitivity. responded more sensitively to the positive stimulation than subjects with the high BIS sensitivity. Therefore, our results suggest the possibility of correlation between BAS/BIS sensitivity and positive/negative emotional stimuli.

The purpose of this study was to identify the reexamination effects of behavioral activation·inhibition scale(Choi & Huh, 2010) on self-determination in order to analysis situational structure for P·E class which is perceived by students. To obtain the purpose, 656 high-school students from Gyeonggi-do area answered questionnaire using convenient sampling method. Data which is obtained through self-administration was analyzed using by the frequency analysis, multiple reguression analysis, EFA, and CFA with SPSS 18.0 and AMOS 16. Results were as followed. First, the more students have friend relation, teacher behavior, emotion change, and positive class attitude that are sub-factors of behavioral activation·inhibition, the more they have self-determination. Second, the less students have typical class structure, negative teacher's attitude, punishment, and lack of self-efficacy, the more they have self-determination. Overall results were discussed for practical application in P·E class.

The common features of the behavioral inhibition and the action monitoring that are considered as one of the executive functions were investigated using event-related brain potentials (ERPs) and source localization analysis. The electrophysiological correlates of behavioral inhibition and action monitoring ate analyzed when the subjects performed the Go/NoGo task. Two ERP components of behavioral inhibition termed as N200 and P300 in NoGo condition were differ from those of Go condition, that is the amplitudes of NoGo N200 and P300 are largest on the fronto-central region, which may reflect the inhibitory control of frontal lobe required in NoGo condition. The error-related negativity (ERN) observed on the fronto-central region when the subjects committed error was much larger in amplitude and faster in latency than those of the correct-related negativity (CRN), which may indicate that the signal of action monitoring is much more required for the error response. The correlation analysis for the ERP components of behavioral inhibition and action monitoring revealed the significant negative correlation among the latencies of NoGo N200 and P300 and the amplitude of ERN, which may reflects that the faster subjects inhibit response, the more monitor their own action. The close relationship between behavioral inhibition and action monitoring was also supported by the results of source localization analysis, which showed the common neural sources of NoGo N200 and ERN was anterior cingulate cortex.

Objective : Impaired response inhibition has been suggested to play an important role in the pathophysiology of obsessive-compulsive disorder (OCD). The aim of this study was to evaluate the response inhibition in patients with OCD, by using the Go/NoGo paradigm, and to better understand its associations with clinical symptoms. Methods : The participants included 63 OCD patients and 80 healthy volunteers matched in age and sex. response inhibition was evaluated using computerized Go/NoGo task, in which their commission error rates, omission error rates, and mean response times were measured. The severity of clinical symptoms in the OCD patients was assessed using Montgomery-Asberg Depression Scale and Yale-Brown Obsessive Compulsive Scale. Result : OCD patients showed significantly impaired inhibition and higher omission errors rates despite their slower response time, compared to normal controls. Clinical symptoms were not correlated with commission errors and omission errors. Conclusion : The present results indicate that impairment in response inhibition may play a critical role in the pathophysiology of OCD as a trait. These findings suggest that deficit of response inhibition may contribute to developing and maintaining clinical symptoms such as compelling need to repeat certain actions in patients with OCD.

The purposes of this study were to look at the patterns of Korean preschoolers' cortisol levels at home and to examine the relations of cortisol pattern to the preschooler's internalizing behavioral tendency with focused on behavioral inhibition and internalizing problematic behavior. The subjects of the study were forty 4-year old preschoolers(27 boys and 13 girls). Saliva was collected at home during the weekends, and cortisol was analyzed by Radioimmunoassay procedure. "Strange Peer Situation Experiment" developed by Rubin, Coplan, Fox and Calkins(1995) and revised by Rubin, Burgess and Hastings(2002) was used to measure the preschooler's behavior inhibition. Problematic behavior was measured through a "Korean Children's Behavior Checklist" (Oh, K. J., Lee, H. R., Hong, K. E., & Ha, E. H., 1997). The results were as follows: First, on average for a 4-year old, the level of cortisol was 0.22 in the morning, and 0.14 in the afternoon. There was a pattern that cortisol levels had declined in the afternoon. There was no difference in cortisol levels between genders. Secondly, there was a tendency that children of higher inhibition level at the lab showed the higher cortisol levels in the morning. However, this difference was not statistically significant. Thirdly, the higher the cortisol levels at home, the more showed internalizing behavior. Externalizing behavior was not correlated with the cortisol levels. It was concluded that cortisol may be related to children's internalizing behavior tendency.

The purpose of the present study was to investigate the differences of nonlinear characteristics of electroencephalogram (EEG) depending on different sensitivities of behavioral activation system (BAS) and behavioral inhibition system (BIS) of young and elderly groups. The EEGs from Fpl and Fp2 electrodes were recorded during resting condition. The young and elderly groups consisted of 19 and 31 healthy right-handed volunteers, respectively. We estimated 1/f scaling exponent which reflects the nonlinear dynamical complexity of EEG. As results, we found the differences of 1/f scaling exponent between young ant elderly BAS sensitive groups. The 1/f scaling exponent of young BAS sensitive group showed significantly higher values than those of elderly BAS sensitive group at the left prefrontal area (Fpl). The young BAS sensitive group had also a tendency to higher 1/f scaling exponent at the right prefrontal area (Fp2). Decrease of the 1/f scaling exponent indicates the increase of complexity and the decrease of the amount of information related to the statistical distribution. Therefore, the elderly BAS sensitive group has higher complexity than young BAS sensitive group, though they were all classified as BAS sensitive group by BAS/BIS scale. Our results suggest the possibility of correlation between BAS sensitivity an4 age.

This study is aimed to inspect how the different sensitivities in Behavioral activation system (BAS) and Behavioral inhibition system (BIS) modulate on the properties of physiological responses stimulated by positive or negative affective sound. We measured the electroencephalogram (EEG) of 32 students, consisted of four groups depending on the BAS and BIS sensitivities, during listening to meditation music or noise. The EEG was recorded at Fp1 and Fp2 sites. After listening to music or noise, subjects reported the affect induced by the sound. For EEG, the power in the alpha band at Fp2, especially in the alpha-2 band (9.0-11.0 Hz) increased during the subjects listening to music, while the power at Fp1 increased during noise. During listening to meditation music, there is a tendency that the left-sided activation in prefrontal cortex (PFC) is positively correlated with the difference of BAS(Z)-BIS(Z). During listening to noise, there is a tendency that the right-sided activation in PFC is dominant in case any of the sensitivity of BAS or BIS is high. From these results we suggest that the physiological responses of different individuals in BAS and BIS react differently under the same emotionally provocative challenge.

Neurodevelopmental disorders are complex conditions that pose difficulty in the modulation of proper motor, sensory and cognitive function due to dysregulated neuronal development. Previous studies have reported that an imbalance in the excitation/inhibition (E/I) in the brain regulated by glutamatergic and/or GABAergic neurotransmission can cause neurodevelopmental and neuropsychiatric behavioral deficits such as autism spectrum disorder (ASD). NMDA acts as an agonist at the NMDA receptor and imitates the action of the glutamate on that receptor. NMDA however, unlike glutamate, only binds to and regulates the NMDA receptor subtypes and not the other glutamate receptors. This study seeks to determine whether NMDA administration in mice i.e., over-activation of the NMDA system would result in long-lasting behavioral deficits in the adolescent mice. Both gender mice were treated with NMDA or saline at early postnatal developmental period with significant synaptogenesis and synaptic maturation. On postnatal day 28, various behavioral experiments were conducted to assess and identify behavioral characteristics. NMDA-treated mice show social deficits, and repetitive behavior in both gender mice at adolescent periods. However, only the male mice but not female mice showed increased locomotor activity. This study implies that neonatal exposure to NMDA may illicit behavioral features similar to ASD. This study also confirms the validity of the E/I imbalance theory of ASD and that NMDA injection can be used as a pharmacologic model for ASD. Future studies may explore the mechanism behind the gender difference in locomotor activity as well as the human relevance and therapeutic significance of the present findings.

The purpose of this study was to examine early emotionality and mothering and fathering antecedents of inhibition of children at age 3 years in a sample of 100 children(51 boys; 49 girls). In order to assess child's behavioral inhibition and mothering, the behaviors of each child-mother dyad was videotaped in a structured lab situation. Data on Fathering behavior were gathered through questionnaires. 2X2ANOVA, Hierachical Regression Analyses and Fisher's Z test were conducted for the statistical analyses. The main results were as follows; 1) Only small portion of the variance in subsequent inhibition could be explained by early emotionality(i.e.negative, positive, and the interaction of both emotionality). 2) High negativity coupled with low positivity in infancy predicted high inhibition especially for girls. 3) In general, sensitive mothering and appropriateness of mothers' response were related to child's low inhibition, while parental intrusiveness and negative affect increased child's inhibition. 4) Mothering appeared more influential in the case of children who showed low positivity during infancy. The importance of distinguishing positive and negative emotionality in infancy and studying parental behavior to predict child's inhibition were discussed.
