<p>The manuscript presents a novel and interesting work for the scientific literature in psychology, is original and increases knowledge about how the cultural context influences intellectual activity in adolescents. Also, this manuscript presents a quantitative investigation, an adequate sample has been used to achieve the objective of the study and the data analyzes are appropriate. The results derived from the work provide interesting information for the educational practice and the field of psychology.</p>
<p>The work is grammatically correct, although it has some small spelling errors (ie. Page 2-3 the sentence is cut; page 3, line 7 "intellectual level of a adolescent"). In order to improve the manuscript, I include some recommendations:<br>1.The introduction section is not very clear. The introduction begins to give way to a review of the literature that includes different approaches to the object of study, but the references used are obsolete and information on the current state of the matter is not included, making it difficult for the reader knows if there are previous studies that support the cultural influence on intellectual activity and to what extent this influence occurs. It would be important to include information on similar studies in that cultural study groups or in other countries. In addition, all this information should be grouped and organized in a clear way, grouping the introduction and review of the literature so that the introduction leads to the objective of the work.</p>
<p>2. The method should be divided into sections such as participants, instruments, design and procedure, and data analysis to facilitate the reading and understanding of this section.</p>
<p>3. Participants should include the number of men and women for each subsample.</p>
<p>4. The design and procedure section should include the beginning of the method section where the part of the information definition is described. It would have to indicate how the selection of the participants was made, what inclusion criteria there were, why those specific schools were chosen. In addition, include how the instruments were administered, whether they were performed individually or during a class while everyone was together, how long it lasted approximately.5</p>
<p>5. Regarding the results, the tables could be grouped to facilitate their understanding. Table 1 and 2 can be grouped into a single one, as well as Tables 3 and 4. In such a way that at the same time that you see the mean scores for each sample in the table, you can check if there were significant differences between the groups.</p>
<p>6. It would be interesting to include the effect size in the results (Cohen's d) and to interpret the magnitude of the effect size in results section.</p>
<p>7. Regarding the discussion section, this section should be expanded and results further discussed based on new scientific literature that has analyzed the cultural influence on intelligence, and it would also be important to include limitations of this work as well as future lines of research.</p>
