Transactive memory in decision-making teams: implications for team effectiveness

The transactive memory system (TMS) construct is one of the most extended theoretical approaches to understand the role of cognitive processes at group level in the effectiveness of work teams. This study examined the relationships among TMS, performance, satisfaction and functional communication in decision-making teams. 40 four-person teams were asked to suppose they were expert consulting teams advising a fictitious organization on how to solve a problem with their employees. Results showed a mediating effect of TMS on the relationships between functional communication, perceived team performance and satisfaction. Contrary to our expectations, TMSs were not related to performance as evaluated by external raters. These findings suggest the importance of team communication in the formation of TMSs, as well as their implications for the effectiveness of decision-making teams.     

Sexuality in children 9-14 years old

The aim of this study was to analyze sexual behaviors and attitudes of children 9-14 years old in Spain. In this article we present data from 470 children of which 52% are boys and 48% girls. In order to evaluate the sample, Information, Attitudes and Behaviors related to Health Questionnaire (CIACS-II) was used. Results evidence that boys 9 years old already show behaviors that evidence their interest towards sexuality. 8% have sometimes masturbated and 9% have used pornography for becoming excited. 14% of children 11-12 years old have already had sexual relations and 38% state to have sexual fantasies. Girls start to masturbate and to have sexual relations later than boys and show a prevalence of sexual fantasies and use of pornography very lower. It is necessary sexual education programs to be implanted since early ages in schools.     

Conceptualizing and testing random indirect effects and moderated mediation in multilevel models: new procedures and recommendations

The authors propose new procedures for evaluating direct, indirect, and total effects in multilevel models when all relevant variables are measured at Level 1 and all effects are random. Formulas are provided for the mean and variance of the indirect and total effects and for the sampling variances of the average indirect and total effects. Simulations show that the estimates are unbiased under most conditions. Confidence intervals based on a normal approximation or a simulated sampling distribution perform well when the random effects are normally distributed but less so when they are nonnormally distributed. These methods are further developed to address hypotheses of moderated mediation in the multilevel context. An example demonstrates the feasibility and usefulness of the proposed methods.     

Risky assessments: participant suicidality and distress associated with research assessments in a treatment study of suicidal behavior

The purpose of this study was to examine patterns of self-reported suicidality and distress during research assessments in a sample of 63 women meeting criteria for borderline personality disorder and current and chronic suicidality. The risk management protocol we used during the two-year study period (University of Washington Risk Assessment Protocol; UWRAP) is described. Results indicated that changes in suicidality following assessments were small and relatively infrequent, and were just as likely to reflect decreases in suicidality as increases (17.5% versus 16.4% of sessions, respectively). Further, longitudinal analyses indicated that changes in suicidality became increasingly rare over the course of the 2-year study. Ratings of distress were more changeable than suicidality, underscoring the need for separate measurement of these constructs when assessing risk. With the aid of the UWRAP, our assessors judged 15 participants as high-risk status in 28 assessment sessions (3.7% of all sessions). In comparison to the rest of the sample, these individuals were of significantly greater clinical severity as measured by the HRSD 17-item, GAF scores, number and severity of previous suicide attempts, and number of previous psychiatric hospitalizations. Low-intensity risk intervention strategies (e.g., validating participant's feelings) were typically sufficient to reduce risk in these participants. Overall, our findings indicate that research with highly suicidal individuals can be done safely with the use of well-trained assessors and an appropriate crisis management protocol.     

Embodied temporal perception of emotion

The role of embodiment in the perception of the duration of emotional stimuli was investigated with a temporal bisection task. Previous research has shown that individuals overestimate the duration of emotional, compared with neutral, faces (S. Droit-Volet, S. Brunot, & P. M. Niedenthal, 2004). The authors tested a role for embodiment in this effect. Participants estimated the duration of angry, happy, and neutral faces by comparing them to 2 durations learned during a training phase. Experimental participants held a pen in their mouths so as to inhibit imitation of the faces, whereas control participants could imitate freely. Results revealed that participants overestimated the duration of emotional faces relative to the neutral faces only when imitation was possible. Implications for the role of embodiment in emotional perception are discussed.     

A multilevel model of safety climate: cross-level relationships between organization and group-level climates

Organizational climates have been investigated separately at organization and subunit levels. This article tests a multilevel model of safety climate, covering both levels of analysis. Results indicate that organization-level and group-level climates are globally aligned, and the effect of organization climate on safety behavior is fully mediated by group climate level. However, the data also revealed meaningful group-level variation in a single organization, attributable to supervisory discretion in implementing formal procedures associated with competing demands like safety versus productivity. Variables that limit supervisory discretion (i.e., organization climate strength and procedural formalization) reduce both between-groups climate variation and within-group variability (i.e., increased group climate strength), although effect sizes were smaller than those associated with cross-level climate relationships. Implications for climate theory are discussed.     

Teacher and parent perceptions of behavior problems among a sample of African American,Hispanic, and non-Hispanic white studients

A multiracial/multiethnic sample of middle school adolescents and their teachers was used to assess whether teacher ratings of student behavior problems varied according to teacher-student racial/ethnic differences and students' perception of teachers' attitudes toward them. No significant mean score differences were found for Hispanic or non-Hispanic white students according to the race/ethnicity of the teachers doing the ratings. However, African American students rated by Hispanic and non-Hispanic white teachers had significantly higher mean total behavior problem scores than African American students rated by African American teachers. Teacher ratings were also compared to those made by parents. The percentage of students rated as cases by teachers but not by parents differed significantly by race/ethnicity of student. Other findings indicated highly significant relationships between student-perceived teacher disparagement and the assignment of high behavior problem scores to students by teachers.

The authors express their appreciation to Superintendent Octavio Visiedo, Dr. James Mennes, Dr. Sylvia Rothfarb, and the cooperating staff and teachers of the Dade County Public Schools for their support in the conduct of this research.
