It has been hypothesized the greater left frontal activation reflects the positive (approach) behaviors, whereas the greater right frontal activation reflects the negative (withdrawal) behaviors. However, the role of hemispheric lateralization on emotions is still debated. Moreover, the frontal electrodes consisting of F4/F3 and F8/F7 pairs are commonly used in FAA analysis, but few studies have examined the role of different frontal electrode pairs. This study aimed to clarify the FAA in response emotional clips comparing to resting-state and the influence of difference pairs of frontal sites (F4/F3: medial–frontal sites vs. F8/F7: lateral–frontal sites). The participant were 10 healthy females (aged 20–32 years; M = 25.80, SD = 4.85). Two sets of emotional clips (4 clips per set) were used to elicit target emotional states (sadness, fear, happiness, and neutral). The FAA was calculated using the equation: ln[right] − ln[left] alpha power (8.5–13 Hz). The results found the significantly decreased FAA at F4/F3 pair in response to negative clips (sad; t(9) = 2.787, p = 0.021, fear; t(9) = 2.344, p = 0.044) and significantly increased FAA at F8/F7 pair in response to neutral clips (t(9) = −2.902, p = 0.018) when compared to resting-state. Moreover, the significantly changes among emotional clips can be detected from FAA. All FAA scores from F4/F3 were positive, whereas most FAA scores from F8/F7 were negative. These findings indicated that FAA is associated with emotional response, especially with negative stimuli, and is still valuable tool for studying affective response. However, the selection of frontal electrode pairs is also important. Finally, the difference of alpha power between left and right frontal electrodes seem to be more important than positive or negative FAA values.

Amygdala and prefrontal cortex are the important brain structures involved in emotional processing. Frontal alpha (8.5-13 Hz) asymmetry (FAA) has been received most attention to be a neuro-biomarker of emotion, but the brain asymmetry on other spectral frequencies, particularly in frontal theta (4.5-8 Hz) asymmetry (FTA), are needed to be clarified. This study aimed to investigate the FTA in response to emotional clips and the influence of difference pairs of frontal sites (F4/F3: medail-frontal vs. F8/F7: lateral-frontal). The participant were 10 healthy females (aged 20-32 years; M = 25.80, SD = 4.85). Two sets of emotional clips (4 clips per set) were used to elicit target emotional states (sadness, fear, happiness, and neutral). The FTA was calculated using the equation: ln[right]–ln[left] theta power. The results found the significantly decreased FTA at F4/F3 pair in response to negative and neutral clips when compared to resting-states. The significant reduction of FTA among types of emotional clips was obviously demonstrated at F4/F3 pair. However, only one pair of emotional clip (fear and happiness) can be revealed with FTA at F8/F7 pair. These findings indicated that FTA can be used for studying emotional response, especially with negative stimuli, and may be a valuable tool as a neuro-biomarker of emotion apart from the FAA. However, the selection of frontal electrode pairs is important. The FTA between dorsolateral-prefrontal electrodes seem to be sensitive with emotional response than the FTA between ventrolateral-prefrontal sites.

The research samples include executives, teachers and middle-school students of Nakhawittayakom School in Mahasarakham Province in academic year 2013, accounted for 76 people in total. Twenty-two executives and teachers were selected through purposive sampling. Fifty-four students were selected from multistage sampling.
The research instruments were 1) self-assessment reports of academic year 2011 of Nakhawittayakom School; 2) focus-group interviews for teacher, executive and student groups on the topic of problems and needs of developing students’ learning processes of Nakhawittayakom School in Mahasarakham Province through notes and tape recording; 3) questionnaires about problems and needs of developing students’ learning processes of Nakhawittayakom School in Mahasarakham Province.
Data procedure and data analysis were conducted through qualitative research. In conclusion, the data were written by descriptive analysis to examine accuracy and reliability to use empirical data to conduct as questionnaires. Then the questionnaires would be brought back to the responders to ensure the reality. Also, the data would be brought for priority setting through PNI-modified Priority Needs Index with the formula of PNI modified = (I – D)/D
Research Results The top five priorities of problems and needs of developing students’ learning processes of Nakhawittayakom School in Mahasarakham Province in terms of school policies and management were ranked as follows 1) classroom facilities such as desks, chairs, fans and temperature stimulated learning efficiency; 2) the number of ICT media was enough for the demand; 3 ) the number of necessary material was enough for the demand; 4) personnel had enough expertise such as art, music and dancing art; 5) the school supported job creation and supplement career for the students. The top five priorities of problems and needs of developing students’ learning processes of Nakhawittayakom School in Mahasarakham Province in terms of teachers were ranked as follows 1) the teachers understood the research process; 2) the teachers had capacity to teach by using project-based learning; 3) the teachers had capacity to give lesson that improve student’s analytic and synthetic skills; 4) the teachers received continue developing and supervision in learning management; 5) the teachers had capacity to generate ICT medias. The top five priorities of problems and needs of developing students’ learning processes of Nakhawittayakom School in Mahasarakham Province in terms of students were ranked as follows 1) the students had abilities in foreign language communication; 2) the students understood the learning through research processes; 3) the students had diverse techniques for knowledge exchange; 4) the students reached the expected O-Net score of the school; 5) the students were able to think, do and solve problems. The top ten priorities of problems and needs of developing students’ learning processes of Nakhawittayakom School in Mahasarakham Province were ranked as follows 1) the students had abilities in foreign language communication; 2) the students understood the learning through research processes; 3) classroom facilities such as desks, chairs, fans and temperature stimulated learning efficiency; 4) the number of ICT media was enough for the demand; 5) the number of necessary material was enough for the demand ; 6) personnel had enough expertise such as art, music and dancing art; 7) the students had diverse techniques for knowledge exchange; 8) the students reached the expected O-Net score of the school; 9) the school supported job creation and supplement career for the students; 10) the students were able to think, do and solve problems.

The difference between age groups, gender, and the limitations of using this test with Thai kindergarteners were examined, too. The subjects in this study were 386 students, whose ages ranged from 3 years and 6 months through 6 years and 5 months, studying in kindergarten.
The result found that normal Thai children attained a mean raw score on the Beery VMI at a younger age than normal American children. There were 32 children (8.29%) who had a below average score for visual-motor integration. The mean of the Beery VMI, 5th edition of Thai kindergarteners between age groups was significantly different at the level of 0.001. Kindergarteners in the age range from 3 years and 6 months through 3 years and 11 months had the lowest mean of the Beery, VMI 5th edition, while the 6 years to 6 years 5 months kindergarteners had the highest. Also the finding indicates that the mean of the Beery VMI, 5th edition increased as the age of the group increased. For the gender variable there was no significant difference at the level of 0.05 between boys and girls.
The findings revealed that the Beery VMI, 5th edition was effective in evaluating visual-motor integration of Thai kindergarteners for planning intervention and special training.
