A Stochastic Model of Personality Differences Based on PSI Theory

Round 1

Reviewer 1 Report

This is an important research study modeling personality. It would be interesting to see applications of this model.

 

A careful proofreading would help. E.g., p.3, ln.117: please remove the extra space after "response"; p.16, ln.505: "pf"->"of".

 

Please make sure to define acronyms at first use. E.g., p.7, ln.290: "STAR".

 

Please remove the blank spaces on p.11, p.13 and p.15.

 

It is surprising not to see a conclusion for this paper. Adding such a section might be beneficial for readers.

 

it might be of interest to add more discussion about other possible factors that might activate the four systems besides affect.

We would like to thank the reviewer for their kind words and their thoughtful suggestions for improving the presentation of our work!

1. A careful proofreading would help. E.g., p.3, ln.117: please remove the extra space after "response"; p.16, ln.505: "pf"->"of". 

l.117, Space removed (now, l.136), l.527 corrected.

2. Please make sure to define acronyms at first use. E.g., p.7, ln.290: "STAR".

The STAR acronym is now explained in a footnote (p.8).

3. Please remove the blank spaces on p.11, p.13 and p.15.

These blank spaces had to be inserted to avoid floating of figures and tables. This will hopefully be resolved in production.

4. It is surprising not to see a conclusion for this paper. Adding such a section might be beneficial for readers.

This has also been suggested by Reviewer 2 - a brief Conclusions section has been added to the manuscript.

5. it might be of interest to add more discussion about other possible factors that might activate the four systems besides affect.

The authors agree with reviewer 1 that alternative explanations beyond cognition and affect regulation (which are the focus of our current study) should be discussed. In the revised manuscript we have added some sentences describing possible extensions of the mathematical model in the Conclusions section. Also, in the original manuscript, temperament, motives and volition had already been briefly mentioned in the Introduction. We believe that a more detailed discussion would interfere with our goal to provide a self-contained introduction, suitable for readers unfamiliar with the theory, to the aspects of PSI theory that are directly relevant to the model presented here.

Reviewer 2 Report

The article presents one of the modern and original theories of personality: Personality Systems Interactions (PSI) theory. Currently, this theory is gaining more and more popularity in different countries of the world, and the publication of this article will undoubtedly contribute to PSI theory popularization. It is very important that the article presents the substantiation and confirmation of the main provisions of the theory with the help of mathematical modeling.

The article is written in good scientific language in accordance with the requirements for modern scientific publications. The content of all sections of the article complies with the rules.

I read the article with pleasure and, in general, I rate this article very highly.

I have only a few small comments and recommendations that, in my opinion, will help improve the text.

1.    I suggest adding " PSI theory" to the keywords

2.    I believe that 14 sources in the list of references are not enough for a modern article on a topical issue. The authors cited only 5 publications in English on PSI theory (line 49), but I think publications in other languages, such as Spanish, can be included to show the popularity of the theory.

3.    In my opinion, the article lacks brief Conclusions, which will present possible practical applications of this study, as well as prospects for further research.

 I wish the authors success!

1. I suggest adding " PSI theory" to the keywords

“PSI theory” has been added to keywords (p.1).

2. I believe that 14 sources in the list of references are not enough for a modern article on a topical issue. The authors cited only 5 publications in English on PSI theory (line 49), but I think publications in other languages, such as Spanish, can be included to show the popularity of the theory. 

Many more references have been added to the manuscript, including one in Spanish.

3. In my opinion, the article lacks brief Conclusions, which will present possible practical applications of this study, as well as prospects for further research.

This has also been suggested by Reviewer 1 – a brief Conclusions section has been added to the manuscript.

I wish the authors success!

We would like to thank the reviewer again for this encouragement.

Reviewer 3 Report

Thanks for an interesting and well-written manuscript investigating dynamical behaviour of a differential equation model for the PSI theory.

 

I only had one minor suggestion:

In line 234 you specify that b_t^+ = b_t^- initially, but ælater on (in line 324) you make this assumption always.

We thank the reviewer for their kind words.

I only had one minor suggestion:

We have rewritten the sentence to clarify that b_t^+ = b_t^- =0 is assumed in our study, see ll.253-255.
