Original Text: Letter-3

We exerted changes that you proposed to us. Our answers to your questions are:
1- About your first question: we used 250 volunteer students with accessible sampling method then by applying so many exclusion criteria only 80 subjects remained. Because of our study type (a comparative study) and our instruments (they were so many and time consuming) 40 persons in each group were sufficient.
2- About your second question: our primary assumption was ; BA and BS students have at least normal IQ, but for excluding subjects with high IQ, in the last stage of forming groups, we used Raven IQ test and then excluded them (only 5 persons had more than 110 IQ that were excluded).at first Because of few number of them(5 person) we didn’t mentioned but at this stage we add it.
3- About your third question: WCST is a one of the most popular and available neuropsychological instrument, although it is not as accurate as imaging instruments like fmri and EEG but it can show differences in function of the frontal lobe, so we believe that our study is a neuropsychological study but is not perfect and it can play role as starter for more accurate studies in this area. Furthermore in the last part of our study this problem was mentioned as weak point and restriction of our study.
4- But your question about executive functions: we didn’t designed our study about executive functioning because resent studies have showed that in addition to frontal lobe, many other areas (like posterior regions) of the brain have role in executive functions but our aim was to investigate about Emotional Intelligence and it’s relation to prefrontal cortex (in the other word anterior regions of the brain). Our question was” can we attribute emotional intelligence to anterior regions of brain as like as IQ that is more attributed to posterior regions?. In the other word we want to answer to this main question: “Is success of people with normal IQ and low EQ more related to differences in function of anterior regions of brain (frontal lobe) instead of posterior regions (other three lobe)?” although we know that answer to this question needs too more accurate and specific studies.

Revised Text:

We have made the changes that you proposed to us. Our answers to your questions are:

1- First question: we used 250 volunteer students with accessible sampling methods. After applying several exclusion criteria, only 80 subjects remained. Because of the study type (a comparative study) and our instruments (they were numerous and time consuming), 40 persons in each group were sufficient.

2- Second question: Our primary assumption was that BA and BS students have at least a normal IQ. For excluding subjects with high IQ's in the last stage of forming groups, we used the Raven IQ test and excluded those (5 persons) with an IQ of greater than 110. At first, due to the small number, we didn’t mentioned them but at this stage we added the information.

3- Third question: WCST is a one of the most popular and available neuro-psychological instruments. Although it is not as accurate as imaging instruments like fmri and EEG, it can show differences in function of the frontal lobe, so we believe that our study is a neuro-psychological study. While not perfect, it can play a role as starter for more accurate studies in this area. Furthermore, in the last part of our study this problem was mentioned as a weak point and restriction of our study.

4- Your question about executive functions: We didn’t design our study for executive functioning because recent studies have shown that, in addition to the frontal lobe, many other areas (like the posterior regions) of the brain have a role in executive functions. Our aim was to investigate Emotional Intelligence and its' relationship to the prefrontal cortex (in other words, the anterior regions of the brain). Our question was, ”Can we attribute emotional intelligence to anterior regions of the brain as well as IQ, which is more attributed to the posterior regions?"

In the other words, we want to answer this main question: “Is success of people with a normal IQ and low EQ more related to differences in function of anterior regions of the brain (frontal lobe) than the posterior regions (the other three lobes)?” We know that, to answer this question, more accurate and specific studies are needed.
