Behavioral Genetics and Predisposition to Aggressive Behavior

This paper is an introduction to behavioral genetics for researchers and practioners in language development and disorders. The specific aims are to illustrate some essential concepts and to show how behavioral genetic research can be applied to the language sciences. Past genetic research on language-related traits has tended to focus on simple etiology (i.e., the heritability or familiality of language skills). The current state of the art, however, suggests that great promise lies in addressing more complex questions through behavioral genetic paradigms. In terms of future goals it is suggested that: (a) more behavioral genetic work of all types should be done—including replications and expansions of preliminary studies already in print; (b) work should focus on fine-grained, theory-based phenotypes with research designs that can address complex questions in language development; and (c) work in this area should utilize a variety of samples and methods (e.g., twin and family samples, heritability and segregation analyses, linkage and association tests, etc.).

Quality Of Health Services

Abstract. The quality of health services depends on the contribution of all the professionals involved in the system, including certain groups, usually forgotten and underrated, such as the health-transport technicians (HTT). With the aim of improving this group's performance, an intervention program, focusing on the development of the workers' technical and social skills, was designed in a collective of enterprises. Information about the first stage of this program, consisting of the assessment of these workers' social skills, is offered in this study. A specific questionnaire was developed: The Health-Transport Technicians Social Skills Questionnaire (HTT-SSQ), made up of three scales (assertive, passive, and aggressive behavior). It was administered to a large sample (N = 530) from the above-mentioned association. The psychometric properties of the questionnaire were analyzed, with quite satisfactory indexes of internal consistency and factor validity, and the group's deficiencies (excess or deficit) were evaluated.

The Social

This article explores commonly discussed theories of violent video game effects: the social learning, mood management, and catharsis hypotheses. An experimental study was carried out to examine violent video game effects. In this study, 103 young adults were given a frustration task and then randomized to play no game, a nonviolent game, a violent game with good versus evil theme (i.e., playing as a good character taking on evil), or a violent game in which they played as a “bad guy.” Results indicated that randomized video game play had no effect on aggressive behavior; real-life violent video game-playing history, however, was predictive of decreased hostile feelings and decreased depression following the frustration task. Results do not support a link between violent video games and aggressive behavior, but do suggest that violent games reduce depression and hostile feelings in players through mood management.
