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.

Purpose: The descriptive correlational study was designed to examine the relationship of eating behavior to depression, trait anger, anger expression, Behavior Activation System(BAS) and Behavior Inhibition System(BIS) in adolescent women. Method: 437 women aged 15 to 18 years were recruited from two high schools located in Seoul, Korea. The instruments used were SCL's depression scale, Spielberger's state trait anger expression inventory-Korean version for trait anger and anger expression, the Korean-BAS/BIS scale for behavior activation system and behavior inhibition system, and Eating Attitude Test(EAT-26) for eating behavior. Results: The score of EAT significantly correlated with depression, trait anger, anger expression, BAS and BIS. The EAT score also had a significant relationship with anger-in and anger-out. Depression only correlated with the dieting among factors of EAT, Trait anger, anger-in and anger-out showed a significant correlation with EAT factors such as dieting and oral control. BAS significantly correlated with dieting; whereas, BIS revealed a relationship with bulimia/food preoccupation. Conclusion: Based on this results, various variables need to be included for a nursing intervention program leading to healthy diet behaviors of adolescent women.

To inspect how the different sensitivities in BAS (or BIS) moderate on the HRV pattern stimulated by positive or negative affective sound, we measured the electrocardiogram (ECG) of 25 students, consisted of 4 groups depending on the BAS (or BIS) sensitivity, while listening music or being exposed to noise. The power spectral density of HRV was derived from the ECG, and the power of HRV was calculated for 3 major frequency ranges (low frequency [LF], medium frequency [MF], and high frequency [HF]). We found that the index MF/(LF+HF), while listening music, was 20 % higher in the individuals with a low BIS but high BAS than in the individuals with a low sensitivity In both BIS and BAS. Moreover, in the former group this index was 30 % higher while listening music than while being exposed to noise. From these results we suggest that individuals with a low BIS but high BAS be more sensitive to positive affective stimuli than other groups, and the index MF/(LF+HF) be applicable to evaluate positive affects.

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.

Generic medicine (GM), which is an alternative drug product for branded medicine (BM), is used less in Japan than in other OECD countries. Therefore, we investigate why the medical consumers of Japan avoid the use of GMs even though the efficacy and safety of the medicines have already been proven. We theorize that effectiveness or risk of GMs are related to the consumer attitude toward GMs is affected by the behavioral approach/activation system (BAS) which promotes actions to reach the desired state, and the behavioral inhibition system (BIS) which suppresses behaviors to avoid negative outcomes. To see which of the BAS and BIS dimensions are related to GM usage, we surveyed 374 Japanese consumers and found that Quality, Efficacy, Safety, & Cost-effectiveness with the BAS, and Functional Risk, Financial Risk, Social Risk, Physical Risk, Psychological Risk, & Time Risk with the BIS had a significant effect on consumer attitude to GMs. These results are important in that they 1), confirm the role of BAS/BIS in attitudes to GMs, 2), provide guidelines when marketing GMs, 3), help governments promote the use of GMs as a cost-saving measure, and 4), guide future surveys regarding consumer attitudes to GMs.

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.

행동활성화체계(BAS)/ 행동억제체계(BIS)는 서로 독립적이고 구분되는 신경 기저와 작용 방식을 가졌기 때문에 사람들은 이 두 체계에서 각기 독립적인 민감성을 보이리라고 가정할 수 있으며, 개인의 기질이나 성격 특성 및 광범위한 전반적 정서 경험 경향성과도 밀접하게 관련된다고 가정된다. 본 연구에서는 뇌자도(MEG)에서 취득한 신호를 가지고 EEG에서 얻은 신호 및 자기 보고식 질문지를 통한 비교 분석 연구를 수행하였다. 총 9명 (male=6, female=3)을 대상으로 EEG/MEG를 수행한 후 BIS/BAS 질문지를 수행하여 비교 분석하였다. 자기 보고식 질문지와 EEG/MEG와의 상관관계 및 통계분석을 통하여 EEG와 MEG에서 일치성 및 상관성을 살펴보고 향후 성격 및 감성성향 판단 및 분류에 있어서 MEG의 효용성 측면을 살펴보고자 함이 본 연구의 목적이다.

This study was designed to investigate the relations of motivation to related variables, and the motivation by student's variables basically through measure of motivation system about science learning. For this, 496 fourth-grade students and 425 eighth-grade students were required to accomplish a questionnaire on behavioral inhibition/activation system about science learning (SL-BIS/BAS), and self-efficacy. Based on these materials, SLBIS/BAS by student's variables and relations between the system to self-efficacy were analyzed. The result of this study shows the following:First, the sensitivity about SL-BIS in the eighth-grade was higher than in the fourth-grade. But sensitivity about SLBAS and self-efficacy in the eighth-grade was lower than in the fourth-grade Hence, the difference in sensitivity about SL-BIS/BAS agree with difference in motivation. Second, there were low negative correlation with SL-BIS and self-efficacy, and positive correlation with SL-BAS and self-efficacy. In addition, two systems account for 41% of self-efficacy, it showed that SL-BIS/BAS relates to self-efficacy. Through the results of this study, relations of motivation to related variables, and the motivation by student's variables were identified. These results would be helpful for teachers to understand the difference about motivation by students' variables and to make a plan for the appropriate strategies for learners.

The EEG asymmetry of prefrontal lobe has been researched to analyze the affect such as depression or anxiety and the behavioral characteristics such as BIS(Behavioral Inhibition System)/BAS(Behavioral Activational System) on the basiss of alpha band. However there has been several proposals about the importance of beta asymmetry pointing out the limitation of alpha asymmetry. Here, for 44 numbers of 4-year-old children, by comparing alpha asymmetry and beta asymmetry with BIS/BAS results respectively, we propose the way to classify the characteristics of affect and behavioral trend. We also found that BIS is related with beta-asymmetry, while BAS is related with alpha-asymmetry. As for the affective trait, we use the alpha asymmetry following the other results. Our results seem to be consistent with the other results that the synapse formation of young children is more active at the hemisphere than the right hemisphere.
