A Test and Extension of the Demand/Control/Social Support Model: Prediction of Wellness/Health Outcomes in Greek Teachers

The present study investigated the relationship between job characteristics, coping strategies and job satisfaction, burnout and somatic complaints in 215 Greek secondary school teachers in the urban area of Thessaloniki, as part of the EUROTEACH project (11 countries, 2164 teachers). The study aimed at testing the hypotheses of the Demand-Control-Social support model (Karasek, <citeref rid="bib20">1979</citeref>); and examining whether additional job characteristics (working hours, environmental risks, meaningfulness and physical exertion) as well as the inclusion of coping strategies could improve the model. Instruments included the Leiden Quality of Work Questionnaire for Teachers; the SCL-90 somatisation scale; the Maslach Burnout Inventory; and the CISS. Results indicated that all three components of the original model are associated with the outcomes with some associations being nonlinear. However, the moderating effects of control and social support are not supported by the data. Regarding coping, results indicated that coping variables can explain variance in most of the outcomes of the study, in addition to all job characteristics. Regarding the additional job characteristics, meaningfulness of work is the most important predictor. In order to understand these findings better, the Greek data were compared to that of the EUROTEACH group. This comparison revealed that the Greek teachers differ from their European counterparts in most study variables. The direction is mainly to the positive side, with the exception of the experience of less control on the job. The implications of these findings concerning model-based studies on teachers are discussed.     

Performing well in an evaluative situation: The roles of perceived competence and task-irrelevant interfering thoughts

Abstract

This research expands on previous research by arguing and demonstrating that high perceived competence buffers the detrimental effects of an evaluative situation. In Study 1 (n=75, 38.7% male), the situation (evaluative vs. non-evaluative) and perceived competence (high vs. low) were manipulated, whereas in Study 2 (n=42, 33.3% male), perceived competence relied on naturally occurring differences in perceived competence. The results of Study 1 indicate that people may underachieve in an evaluative situation. More importantly, in Study 2 it was demonstrated that such an evaluative situation had only a negative effect on test performance among individuals low in perceived competence. The occurrence of task-irrelevant interfering thoughts during task completion accounted for this inimical effect of an evaluative situation on test performance among these individuals.     

Constructing Confidence Intervals for Effect Size Measures of an Indirect Effect

Confidence intervals for an effect size can provide the information about the magnitude of an effect and its precision as well as the binary decision about the existence of an effect. In this study, the performances of five different methods for constructing confidence intervals for ratio effect size measures of an indirect effect were compared in terms of power, coverage rates, Type I error rates, and widths of confidence intervals. The five methods include the percentile bootstrap method, the bias-corrected and accelerated (BCa) bootstrap method, the delta method, the Fieller method, and the Monte Carlo method. The results were discussed with respect to the adequacy of the distributional assumptions and the nature of ratio quantity. The confidence intervals from the five methods showed similar results for samples of more than 500, whereas, for samples of less than 500, the confidence intervals were sufficiently narrow to convey the information about the population effect sizes only when the effect sizes of regression coefficients defining the indirect effect are large.     

Eyewitness Memory and Metamemory in Product Identification: Evidence for Familiarity Biases

Research on the reliability of eyewitness memory for criminal events has been extensively studied, but eyewitness memory in civil cases has not. However, many of these civil cases revolve around eyewitness memory for events that transpired decades ago. We have developed a paradigm with which to study memory for specific product brand identification, a common question in civil cases involving product liability. Participants were asked to follow recipes and were then given surprise memory tests on the specific brands of products used. In addition, they were asked to report their subjective confidence for each response. Memory and performance was poor after even a brief delay, as was metamemory accuracy: Confidence regarding brand name recall was a poor indicator of accuracy. Participants also displayed a strong familiarity bias. They frequently reported using familiar, common brands, when no such products were actually used. This was especially true at longer delays, after which false identification of familiar products was twice as common as correct responses.     

The development of work discussion groups in educational settings

This paper describes the application and development of the work discussion method within educational settings. In the first section of the paper, I outline some key contextual factors that are important to consider when setting up work discussion groups within schools. A number of case examples are then described, illustrating a range of central issues that can emerge. By developing a deeper understanding about the meaning of behaviour and the emotional factors that impact on teaching and learning, I hope to demonstrate how work discussion groups can help teachers to develop their capacity to manage the challenges of their work, role and relationships with pupils. More broadly, I hope to illustrate how these groups can help to promote a learning environment for all, in which development and growth is promoted at a personal, professional and whole school level.     

Witness Vetting: What Determines Detectives' Perceptions of Witness Credibility?

During the course of a criminal investigation witness vetting, a detective's process of determining the credibility and weight of witness information, can lead to errors in an investigation that can go virtually unchallenged. Witness confidence, opportunity to view, and type of information proffered were examined in relation to detective inferences about witness reliability, accuracy, and probable cause to arrest. Experiment 1 involved 39 sworn law enforcement officers, and experiment 2 involved 43 sworn law enforcement officers and 86 mock detectives. Participants viewed a digital recording depicting a witness describing a gas station robbery (Experiment 1) or a campus mugging (Experiment 2). Witness confidence and detectives' inferences about culprit information influenced the vetting process and lent credibility to a confident witness whose accuracy was objectively unknown. Furthermore, the evidence indicates that sworn law enforcement are comparable with untrained observers in their use of social inference cues (i.e. confidence) in determining witness credibility; however, social inference can be assuaged by the rational, rule‐governed, decision framework established for witness vetting. Social inference processes inherent in the detective‐witness dyad is influenced by legal procedures in vetting witness information. Copyright © 2013 John Wiley & Sons, Ltd.     

Parent–child resemblance and kin investment: Physical resemblance or personality similarity?

Resemblance between parents and children has been suggested as an indicator of kinship. Because men, unlike women, cannot be certain about parenthood, resemblance may influence men more than women when making investment decisions. In the present paper we examine the relation of physical resemblance and personality similarity with parental investment for 90 Dutch parents and their school-age children. For mothers investment was linked to personality similarity, whereas for fathers investment was linked to physical resemblance, suggesting that fathers are influenced by physical cues when making investment decisions, whereas mothers are influenced by psychological cues.     

Intuition, reason, and metacognition

Dual Process Theories (DPT) of reasoning posit that judgments are mediated by both fast, automatic processes and more deliberate, analytic ones. A critical, but unanswered question concerns the issue of monitoring and control: When do reasoners rely on the first, intuitive output and when do they engage more effortful thinking? We hypothesised that initial, intuitive answers are accompanied by a metacognitive experience, called the Feeling of Rightness (FOR), which can signal when additional analysis is needed. In separate experiments, reasoners completed one of four tasks: conditional reasoning (N = 60), a three-term variant of conditional reasoning (N = 48), problems used to measure base rate neglect (N = 128), or a syllogistic reasoning task (N = 64). For each task, participants were instructed to provide an initial, intuitive response to the problem along with an assessment of the rightness of that answer (FOR). They were then allowed as much time as needed to reconsider their initial answer and provide a final answer. In each experiment, we observed a robust relationship between the FOR and two measures of analytic thinking: low FOR was associated with longer rethinking times and an increased probability of answer change. In turn, FOR judgments were consistently predicted by the fluency with which the initial answer was produced, providing a link to the wider literature on metamemory. These data support a model in which a metacognitive judgment about a first, initial model determines the extent of analytic engagement.     

Teacher performance goal practices and elementary students' behavioral engagement: a developmental perspective

We investigated growth trajectories for classroom performance goal practices and for student behavioral engagement across grades 2 to 5 for 497 academically at-risk elementary students. This study is the first longitudinal investigation of performance goal practices in the early elementary years. On average, teacher use of performance goal practices increased and students' behavioral engagement declined across the four years. Using autoregressive latent trajectory (ALT) models, we examined the synchronous relations between teacher-reported performance goal practices and teacher-reported student behavioral engagement. As expected, as students move into classrooms with a new teacher with less emphasis on performance goal practices, they become more behaviorally engaged in school. Gender did not moderate these results. Implications for teacher professional development are discussed.     

Teachers' attunement to students' peer group affiliations as a source of improved student experiences of the school social-affective context following the middle school transition

A randomized control trial examined the impact of a professional development program on rural teachers' attunement to student social dynamics, and the influence of teacher attunement on students' school experiences. In intervention schools serving Latino and White rural early adolescents, teachers (N = 14) received training on social dynamics and aspects of early adolescent adjustment; control school teachers (N = 12) received no training. Social cognitive mapping procedures assessed and compared students' and teachers' perceptions of peer groups; structured observations assessed teachers' management of social dynamics. Students (N = 225) self-reported their perceptions of the school social-affective context. Intervention and control schools differed on teacher attunement and management of the social environment. Students whose teachers were more attuned to peer group affiliations evidenced improved views of the school social environment. Findings are discussed in terms of attunement as an element of teachers' invisible hand, and for teachers' role in promoting productive contexts for students during the middle school transition.
