Number 3 of volume 6 of Psychological Research records incorporates a number original research articles that deal with a wide breath of conceptual issues in a systematic and rigorous fashion. Contributions can be divided into several major categories, two papers deal with psychometric aspects of measures of the sense of community in ones neighborhood and over claims of self maiming. A second category refers to research on basic processes as it is the case of the study on the facial recognition of emotional expressions, and the creation of a structural model of intrinsic motivation and, finally, a study of authoritarianism and its impact on different expressions of prejudice. With an orientation toward research with applied implications, a study of school anxiety and self-concept in adolescents and research project dealing with a macro-social diagnosis of risks of drug use. Finally, with an emphasis on social phenomena, research on the conceptualization and analysis of happiness, its frequency versus its intensity, and the study of individualism and collectivism are published in this issue. As in previous editions, I extend gratitude to the researchers that confer in the magazine their trust to submit their valuable contributions to the knowledge of human behavior, and especially to the reviewers of submitted papers, whos comments, suggestions and evaluations ensure the quality of the published work.
