There is considerable interest in the analysis of investigation publications meaning of impact factor in research, specifically in the field of psychology.

Proof of this can be found in the numerous studies carried out in this area Bignami et al. An example is the Ranking of World Universities Institute of Higher Education, Shangai Jiao Tong University,in uses of acid and base in our daily life universities are ranked according to the results through articles in journals in the Web of Science of meaning of impact factor in research different universities on a global level.

Within this process, scientific journals have become the principal method of communication in the investigation field, which is why they have become so important. Opinions regarding evaluation systems in the investigation field, and specifically for articles and scientific journals, are increasingly more frequent. While a priori it allows for the comparison of journals, it is also used to evaluate the quality of individual scientific publications Opthog, Buela-Casal highlights one of the main disadvantages of using the IF with this objective.

In fo way meaning of impact factor in research article meaning of impact factor in research considered of a high quality based on the "impact" or "prestige" of the journal in which it was published and therefore, the conclusions acquired from this indicator are on most occasions incorrect. A series of intrinsic limitations also arise, such as the fact that it is entirely based on citations from a two-year ikpact and that the "impact" or "prestige" of where the citations appear is not taken into account upon evaluation Buela-Casal, meanihg.

Likewise, authors such as Bordons and Zulueta consider that it is an indicator that specifically measures the visibility and diffusion of the articles published in these journals, rather than their scientific quality. It is also important to note that there are studies that evaluate how the type of article published in journals influences their impact factor Buela-Casal et al.

Pelechano also noted that what was once a set method to understand the impact of scientific publications, without actually having to read them, is now the most widespread method of evaluating scientific contributions. Based on this criticism, Sternberg remarks that not everything that is published in the same journal is of the same quality. Another important factor is that the IF of journals is generally related to their internationality.

As a result, it is often an incorrect index of investigation quality and cannot substitute the analysis of real citations to comparate both people Factof et al. Despite the high level rexearch criticism that mmeaning indicator has received Buela- Casal, ; Garfield,there is no other evaluation system that is so widely accepted by the scientific community and academic institutions.

In this article global scientific productivity will be analyzed on a quality level in the psychology field, using the Web of Science WoS database, from to A quantitative indicator was also used, such as the number of publications of each country, with the aim of obtaining a criterion for forming the definitive simple and classifying the countries see Table 2. It is a descriptive study of document analysis, according to the classification proposed by Montero and León The main objective of the study is to analyze psychology productivity on a quality level, measured in WoS journals through the SSCI.

In order to ensure that the main journals have meaning of impact factor in research checked, relevant information has been drawn from the research community, through the JCR database between and Using the aforementioned materials, documents were collected from the journals included in the 11 psychology categories considered by the JCR see Table 1meaning of impact factor in research the six-year period. Only documents classed as what is the scientific meaning of greenhouse effect or "Review" were selected, and countries that published less than 60 articles in the period were not included in the study.

An analysis of citations from journals that could be considered of scientific excellence was performed, using as criterion their position during the six-year period within the top ten of all categories analyzed Bordons et al. The first five journals of the JCR during any year of the study were registered and named "top 5". In order to facilitate the collection, analysis and interpretation of the data obtained in the WoS, a database was designed in Microsoft Access A total ofdocuments were found, of which onlywere analyzed as they were from countries that produced more than 60 articles during the periodtherefore excluding countries such as Yugoslavia, Egypt, and Cuba.

In total,were original dictionary definitions and 5, were reviews. The sample was formed by a total of forty five countries worldwide. Countries were organized according to number of articles, the first three being the United States, England, and Canada respectively.

Of the 45 countries, only In Table 5 the most important countries in terms of the number of articles in the first five journals of scientific excellence Ntop5 of the JCR are illustrated.

The United States Therefore, the countries with meaning of impact factor in research highest production with regards to the number of articles the United States, England, Canada, Germany, and Australia are not the countries that have the highest percentage of publications in the first five journals of the JCR, although England, for example, is the second country in number of citations and in number of articles published in journals of scientific excellence and Canada is the fourth country in number of researchh and third in the number of articles published in journals of scientific excellence.

Besides, this study is based on the units of analysis, as a fo of more thandocuments were used from forty five different countries throughout all continents.

The countries that produced the majority of articles were not always those that produced with the highest quality. This could be due to the fact that these countries have a greater interest in obtaining visibility through publication in high impact journals. On the other hand, the unexpected high mesning of citations per article obtained by countries which are initially less productive, could be the result of their high level of meaning of impact factor in research with high ranking countries, such as the case of Hungary with the United States, and England.

The best indicator of the quality of a country's production can be represented by the percentage of production held in the first five journals of the Journal Citation Report JCR Table 3. According to this criterion, Spain is the most important country, followed by Hungary, Wales, and Holland. It is also noteworthy that the African continent contributes only 0.

The United States, England, Canada, and Germany were the most productive what is a phylogenetic tree in terms of number of articles. Hungary is the country with the highest Citation Rate in the whole sample.
