In this study we suggest the need to value the relations between prosocial behavior and some personal variables like sex and age in a group of students of preschool educational level of four and five years. We worked with a sample of 92 students (59.8% male and 40.2% female) and the Questionnaire of Prosocial Behavior of Weir and Duveen. The results indicate that, perhaps the instrument has adecuate levels of validity and reliability, there are not statistical relations between age, sex and prosocial behavior, but compared means are major in older students (p <0.018).

In the present study we made a psychometrical analysis of the Emotional Intelligence Questionnaire in a sample of 162 people 20 and 62 aged (42.8% male and 57.2% female) from four organizations at Arequipa, two public, and other two private. The statistical analysis points that the items present an adequate homogeneity according to the item-test correlations, and the questionnaire has a three components structure: Self-knowledge, control and empathic ability, Inadequate management of emotions, and Negative Emotions. Moreover, we calculate the reliability of this instrument by mean of the Cronbach’s Alpha Test, which reports a coefficient of α = 0.733.
