SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

Cognition is an international journal that publishes theoretical and experimental papers on the study of the mind. It covers a wide variety of subjects concerning all the different aspects of cognition, ranging from biological and experimental studies to formal analysis. Contributions from the fields of psychology, neuroscience, linguistics, computer science, mathematics, ethology and philosophy are welcome in this journal provided that they have some bearing on the functioning of the mind. In addition, the journal serves as a forum for discussion of social and political aspects of cognitive science.
Papers will be selected on the basis of their scientific quality and degree of innovation. A paper's theoretical relevance to cognition, overall soundness of the argument and degree of empirical motivation, especially from converging sources, are more important than adherence to specific methodological principles. Because Cognition enjoys a wide readership from many disciplines, authors should explicitly consider the general theoretical issues raised by their work and its relevance to other topics and methods. Material should be suited to the character of the Journal, and should describe work done and methods used in a clear and explicit manner (allowing reproduction of the methods by others).
Cognition occasionally publishes special issues devoted to a research area that has seen rapid recent progress, promising new approaches, and convergence among different disciplines.
Contributions: • Full theoretical and experimental papers on the study of the mind •Brief articles reporting original empirical findings, major theoretical advances or crucial developments that warrant rapid communication to the scientific community •Proposals for special issues on a new and important area in the field •Discussions •Book reviews
Reviewers please refer to Editorial Policy on Reviewing for Cognition.
Cognition publishes many of the most important papers in cognitive science and is the premier international and interdisciplinary journal in the field. It is required reading for anyone who wishes to keep up to date in this exciting research area.
