The use of the effect size in JCR Spanish journals of psychology: from theory to fact

In 1999, Wilkinson and the Task Force on Statistical Inference published "Statistical Methods and Psychology: Guidelines and Explanation." The authors made several recommendations about how to improve the quality of Psychology research papers. One of these was to report some effect-size index in the results of the research. In 2001, the fifth edition of the Publication Manual of the American Psychological Association included this recommendation. In Spain, in 2003, scientific journals like Psicothema or the International Journal of Clinical and Health Psychology (IJCHP) published editorials and papers expressing the need to calculate the effect size in the research papers. The aim of this study is to determine whether the papers published from 2003 to 2008 in the four Spanish journals indexed in the Journal Citation Reports have reported some effect-size index of their results. The findings indicate that, in general, the followup of the norm has been scanty, though the evolution over the analyzed period is different depending on the journal.     

A 'quantum' of truth in a field of lies: the investigation of emotional truth in a child analysis

Following Bion’s ideas of analytical research the author intends to consider the need to pursue emotional truth between patient and psychotherapist in order to produce a psychological development. It is shown through the analysis of a child how emotional falsification can distort first of all the definition of the child identity. Successively the attention is focused on how lies, as an unconscious element that twist the research of the truth, obstruct the development of thoughts able to transform emotions.Using a quantisation physical model of space, the author hypothesises that the transformation of β elements in α elements is always in an unstable equilibrium. The distortion of emotional truth co‐produced by lies affects the oscillation β?α at a primitive level of transformation, changing the “physical” state of the analytical field from conductor to insulator. The most important consequence of the particular point of view suggested by the quantistic model is that in the third analytical space the same definition of α elements or β elements depends on the analyst’s point of view. This change of perspective can vitalise the analytical thinking of patient and analyst during an impasse.     

Testing the predictors of boredom at school: Development and validation of the precursors to boredom scales

Background. Boredom has been found to be an important emotion for students' learning processes and achievement outcomes; however, the precursors of this emotion remain largely unexplored. Aim. In the current study, scales assessing the precursors to boredom in academic achievement settings were developed and tested. Sample. Participants were 1,380 grade 5–10 students in mathematics classes. Method. The Precursors to Boredom Scales were tested for structural and convergent validity with multi‐level confirmatory factor analyses (ML‐CFA), and differences in the perception of the precursors of boredom due to gender were investigated. Results. The first ML‐CFA found support for the structural validity of the Precursors to Boredom Scales. In a second ML‐CFA, the newly developed boredom scales showed good convergent validity with several key aspects of instructional quality. Finally, the results supported previous research that found no gender differences in academic self‐concept and interest. Conclusion. The precursors contained in our scales are empirically separable. Implications of the current findings for research on boredom among students are discussed.     

Lexico-semantic processing in Williams syndrome

People with Williams syndrome, a neurodevelopmental genetic syndrome, typically have good language skills as compared to other cognitive abilities, as far as intellectual disability is concerned. They have a large vocabulary and they frequently use uncommon or rarely-used words. This has led some authors to consider that they have a peculiar semantic system, different from that of people with typical development. In this study, we tested this hypothesis by comparing the performance of a group of young adults with Williams syndrome to a control group using various lexico-semantic tasks, including semantic and phonological fluency. The results indicate that the semantic system of people with Williams syndrome does not seem to differ much from those in the control group because the words they produced were similar to those of the control group with regard to word frequency, length or the typicality of the responses within the categories.     

Influence of the sex and gender in the sexual behavior of adolescents

The aim of this study is to evaluate the relation between gender and sex with the sexual behavior of adolescents. The sample comprised 815 teenagers (M=15.65, Sd.=1.42). The assessment instruments were the BEM Sex Role Inventory, the Sexual Opinion Survey, the Questionnaire of Risk Perception of Bayés and a questionnaire designed for the study. The results revealed that the majority of adolescents do not match the traditional gender stereotypes, defining themselves as adrogynes (34.4%). The teenagers who are defined as adrogynes or masculine carry out more sexual behaviors, and who display more erotophilia. The need to include the variable "gender" as a category of analysis in research on sexual behavior is indicated.     

Social psychological processes in family and school: more evidence on their relative etiological significance for bullying behavior

This study looked at students' perceptions of the three socialization processes of connection, regulation, and autonomy with their parents and teachers, and the relation of these issues to bullying peers. Self-reported data were collected from a representative sample of Norwegian eighth graders (N=2,083, 1,010 boys, and 1,073 girls). Findings partially confirm our hypotheses that we generated from earlier research into general antisocial behavior. For both genders, parent regulation and teacher regulation had a direct impact on bullying behavior. Parent connection and teacher connection also had an impact on bullying behavior, but these effects were indirect and were mediated by regulation and autonomy from parents and teachers. Some of the socialization processes had different impacts on bullying behavior for boys and girls. Parent autonomy and teacher autonomy had impact (although weak) on bullying behavior for boys only. In general, the variables related to the parents were of more importance for bullying behavior than the variables related to the teachers.     

Therapists' verbal behavior category system

This paper presents the theoretical and methodological basis of a therapist's verbal behavior category system that allows us to study clinical psychologists' language from a functional-analytic framework and with a rigorous observation method. The procedure to develop the coding system is explained in detail from a very early stage of exploratory observation, to the systematic observation through the use of The Observer XT software. An analysis of intra- and inter-rater reliability using the kappa coefficient and taking into account the factors that affect the values of Cohen's index was carried out. Results show high levels of observer accuracy (between approximately 87% and 93%) that justify the application of this category system to study therapists' verbal behavior in session.     

Local Identity and the Role of Individual Differences in the Use of Natural Resources: The Case of Water Consumption1

A field study assessed the role of social value orientation (SVO) and identification with the local community on water conservation behavior in Italy. Participants (N = 758) completed a self‐reported questionnaire, during summer and Easter time. It was expected that SVO and local identification would affect cooperation in conserving water resources. Consistent with the hypotheses, the highest levels of voluntary cooperation were detected among prosocial persons with high local identity, while the lowest levels of cooperation were detected among proself persons with low local identity. Other factors (e.g., perception of local authority's legitimacy, place of residence, severity of water scarcity condition) did not affect the hypothesized interaction. The theoretical and practical implications of the findings are discussed.
