Stroop interference is a composite phenomenon: Evidence from distinct developmental trajectories of its components

Only one previous developmental study of Stroop task performance (Schiller, 1966) has controlled for differences in processing speed that exist both within and between age groups. Therefore, the question of whether the early developmental change in the magnitude of Stroop interference actually persists after controlling for processing speed needs further investigation; work that is further motivated by the possibility that any remaining differences would be caused by process(es) other than processing speed. Analysis of data from two experiments revealed that, even after controlling for processing speed using z‐transformed reaction times, early developmental change persists such that the magnitude of overall Stroop interference is larger in 3rd‐ and 5th graders as compared to 1st graders. This pattern indicates that the magnitude of overall Stroop interference peaks after 2 or 3 years of reading practice (Schadler & Thissen, 1981). Furthermore, this peak is shown to be due to distinct components of Stroop interference (resulting from specific conflicts) progressively falling into place. Experiment 2 revealed that the change in the magnitude of Stroop interference specifically results from joint contributions of task, semantic and response conflicts in 3rd‐ and 5th graders as compared to a sole contribution of task conflict in 1st graders. The specific developmental trajectories of different conflicts presented in the present work provide unique evidence for multiple loci of Stroop interference in the processing stream (respectively task, semantic and response conflict) as opposed to a single (i.e. response) locus predicted by historically – favored response competition accounts.

Teacher’s use of praise,clarity of school rules and classroom climate: comparing classroom compositions in terms of disruptive students

Clarity of school rules and teachers’ use of praise are strategies suggested to facilitate a positive classroom climate. Studies indicate difficulties for teachers to use such approaches in classrooms with higher levels of disruption. To study (1) if student-rated clarity of school rules, use of praise, and classroom climate differ between students in classes with lower numbers of disruptive students versus classes with higher numbers, (2) if clarity of school rules and teacher’s use of praise are longitudinally associated with classroom climate, (3) if the possible longitudinal association differs between groups, classes (n = 109) in school grades 5–7 were divided into two groups, based on head teacher ratings of disruptive students in class. Baseline and 12-month follow-up responses collected within a Swedish trial were used to perform multiple regression analysis, to compare groups and to investigate possible longitudinal associations. Students in classes with less disruption rated all variables more positively. Classroom climate deteriorated over time in both groups, even if the low disruption group perceived their climate as more positive at follow up. Clarity of school rules did not substantially contribute to classroom climate longitudinally, whereas teacher’s use of praise to some extent did. The difference in longitudinal associations between groups was marginal, hence our hypothesis on weaker associations in the high disruption group could not be confirmed. Clarity of school rules is not longitudinally associated with classroom climate, but teachers may positively influence the learning environment by giving praise, regardless of level of disruption.     

Examining the narrative roles in suicide notes

The present study examines suicide notes, using a sample of suicide notes from published corpora (N = 50), combined with a sample of recent suicide notes from a suicide website (N = 50). The present study proposes a model of differentiation in completed suicides. The characteristics of the suicide notes were analysed using a content dictionary developed by Giles in 2007, and the data subjected to smallest space analysis. Four themes of suicide completer were discovered: Egoistic Victim, Anomic Hero, Altruistic Professional and Fatalistic Revenger. The implications of these findings and the potential use in therapy work with suicide survivors and those with suicidal ideation are discussed, as well as suggestions for the direction of future research.     

Drawing to reconstruct: Pilot study on acknowledging prisoners' internal and external resources in a penitentiary institution

Since the first offender rehabilitation treatments, all theoretical approaches have been focusing on reducing risk factors that may influence recidivism, without satisfactory results. Recent resilience research has instead shown the important mediating or moderating role of protective factors and provided the theoretical principles for the Good Lives Model Comprehensive. This holistic model suggests the importance of integrating the reduction of risk factors with the reinforcement of protective factors in offenders' treatment programs. This combined action is considered the main condition through which offenders are motivated to change their life and develop a sense of agency on their current life conditions. This article presents a pilot study, aimed at analyzing the feasibility of a psychosocial intervention, based on graphic workshops. The purpose of the intervention is helping prisoners strive toward adaptation in jail, and facilitating the redesign of their life beyond bars. Drawing activities allowed prisoners to enhance their own internal and external resources, and recognize risk and protective factors that could influence their successful reintegration into society. The main limit of this study is directly linked to the setting of the penitentiary institution where the study was conducted, which is characterized by a high prisoners' turn over.     

Time estimation: does the reference memory mediate the effect of knowledge of results?

This study presents evidence for the role of knowledge of results (KR) in the estimation of medium time intervals (4-12 s durations). Experiment 1 tested the hypothesis that KR operates at the same stage of temporal processing as attention. The absence of an interaction of attention and KR is taken as evidence against this hypothesis. Experiments 2 and 3 further studied the effects of KR in a reproduction and a production task, respectively. The effects of KR were small in the reproduction and substantial in the production task. The results are interpreted in terms of a clock-based timing model and the findings taken together converge on the interpretation that KR affects the reference memory (RM), rather than the other components of the model.
