Preface

The publication of the number 3, volume 7, corresponding to the winter 2017 of Psychological Research Records required an increasingly complex process of pear evaluation due to the growing number of manuscripts received for evaluation. In this issue in particular, a series empirical articles of broad conceptual breath and rigorous methodology are included. Contributions can be divided into several major categories; the largest number is related to different facets child development. Among the manuscripts reviewed using double blind refereeing as the evaluation technique, are the following: “Internalizing and externalizing problems in children in relation to coping”; “Mental arithmetic in children and its relation to cognitive abilities”; “Flexibility of episodic memory in preschool children: time and consequence” and, “BRIEF-P (Behavior Rating Inventory of Executive Function-Preschool Version) (Spanish adaptation): Reliability and validity”. Another grouping is related to health: “Construction and validation of an assertiveness scale in doctor–patient relationships”, and “Family functioning and suicide attempts at a public hospital of Argentina”. Other items covered in this issue have to do with psycho-physiological variables and social and cultural phenomena. The article on physiology is “Serotonin-2C receptor agonist Ro 60-0175 decreases the expression of ethanol-induced sensitizations”. And the articles on social and cultural themes are: “Addictive behavior to social network sites and its relationship with the problematic use of the mobile phone” and “Conditioners of satisfaction with life of native peoples in Mexico”. As in previous editions of the journal, I want to express my deep appreciation to researchers that confer their confidence and submit their valuable contributions to the understanding of human behavior.
