Questions versus statements: challenging an assumption about semantic illusions

In previous semantic-illusion research the tacit assumption has been that questions and statements-to-be-verified of similar semantic content lead to a similar proportion of semantic illusions. This assumption was made despite the fact that questions are thought to have different processing demands from those of statements. This paper presents empirical evidence that questions tend to lead to more semantic illusions than do statements-to-be-verified. Two experiments were carried out to provide a direct comparison between the semantic-illusion rates for statements and for questions. In Experiment 1, open-ended questions led to significantly more semantic illusions than did true/false statements. Experiment 2 replicated this effect using multiple-choice response options in the question condition. It is concluded that the syntactic form of a sentence affects the way in which semantic information is processed, and the implications of the findings are discussed.     

Suicidal Behavior in the Western Pacific Region: Characteristics and Trends

Current knowledge of suicidal behavior in the Western Pacific region is relatively limited when compared to other areas of the world. This area is characterized by a wide diversity of social, economic, and cultural aspects that do not permit any homogenous reading of suicide phenomena. Data from countries of the region included in this article suggest the existence of important differences among nations in terms of gender, age, and methods of suicide, as well role of mental illness. In addition, the Western Pacific region appears to be affected by higher rates of suicide than other areas in the world, with signs of progressive worsening in recent years and worrying predictions for the next two decades. The Suicide Trends in At‐Risk Territories (START) Study, initiated by the World Health Organization Regional Office in Manila, seeks to research the incidence of both fatal and nonfatal suicidal behavior in countries of the region and to implement interventions for suicide attempters. This ambitious project is expected to standardize data collection procedures and improve the knowledge cultural factors in suicide.     

Competitive conflict regulation and informational dependence in peer learning

The present set of studies investigates the role of competitive conflict regulation and informational dependence in peer learning. Previous studies have shown that peer work on identical information produces not only confrontation of viewpoints but also competitive conflict regulation, the latter of which is detrimental for learning. Conversely, working on complementary information produces positive interactions but also informational dependence, and good quality information transmission is needed to foster learning. The present research shows that discussion aids (note‐taking and access to the study materials during discussion), a variable related to the quality of informational input, moderated the relationship between information interdependence and learning. This moderation was mediated by competitive conflict regulation: Students who worked on identical information with discussion aids reported more competitive conflict regulation than those without discussion aids, which in turn reduced learning, a pattern that did not appear for students working on complementary information. Moreover, when students worked on complementary information, the good quality of information transmission elicited by discussion aids led to high levels of learning for all students. Contributions to research on resource interdependence, socio‐cognitive conflict, and peer learning are discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

Judging a book by its cover: the unconscious influence of pupil size on consumer choice

Past research suggests that men perceive women with large pupils as especially attractive. We employed an innovative methodology to examine whether this effect influences consumer decision-making. A popular psychology book was published with two slightly different front covers. Both covers contained the same photograph of a woman; however, the woman's pupils on one cover were digitally enlarged. Readers indicated whether they were male or female, and whether they possessed the cover with small or large pupils. A significantly greater percentage of men than women had chosen the cover with the large pupils. None of the participants who attempted to guess the nature of the experiment was correct, suggesting that the influence exerted by pupil size was unconscious. These findings provide further support for the notion that people's judgments are unconsciously swayed by pupil size, and demonstrate that this effect operates in a real world setting.     

Norms and screening utility of the Dutch version of the Children's Depression Inventory in clinical and nonclinical youths

This study aimed to (a) assess relationships between the Children's Depression Inventory (CDI) and DSM-oriented depression and anxiety scales of the Youth Self Report, (b) develop reliable norms for the CDI, and (c) determine CDI cutoff scores for selecting youngsters at risk for depression and anxiety. A total of 3,073 nonclinical and 511 clinically referred children and adolescents from The Netherlands and Belgium were included. Results showed that CDI scores were significantly related to DSM-oriented symptoms of both depression and anxiety. CDI scores correlated highly with depression symptoms and moderately with anxiety symptoms. Norms for the CDI were determined by means of multiple regression analysis and depended on sex, age, and country. CDI cutoff scores for selecting individuals at risk for depression and anxiety as measured by the DSM-oriented depression and anxiety scales of the Youth Self Report were determined by means of multiple regression analysis and receiver operating characteristic analysis. A CDI score of 16 was found to have the most optimal balance between sensitivity and specificity for depression, whereas a score of 21 provided the best sensitivity and specificity for anxiety in a subsample of children. We conclude that the CDI is an effective instrument for screening depression and to a lesser extent anxiety in primary and secondary care centers, before applying further assessment of high-risk individuals.     

Enhancing Emotion-Regulation Skills in Police Officers: Results of a Pilot Controlled Study

Police officers are routinely exposed to situations that elicit intense negative emotions; thus, officers have a particularly strong need for effective methods of regulating such emotions. The main purpose of this study was to investigate whether a manualized emotion-regulation training (Integrative Training of Emotional Competencies; iTEC; Berking, 2010a) can improve the emotion-regulation skills of police officers. First, self-reports of 9 emotion-regulation skills were assessed in a sample of officers (N = 31) and compared to those of a matched community-based control group. Then, the effects of the training on the emotion-regulation skills of officers were evaluated in a time-staggered design with a waitlist control condition. Results indicate that, compared to controls, officers have difficulties in accepting and tolerating negative emotions, supporting themselves in distressing situations, and confronting emotionally challenging situations. The training significantly enhanced successful skill application, especially some skills with which officers reported difficulty applying. These findings suggest that a focus on emotion-regulation skills may be an important component for programs aimed at preventing mental-health problems in police officers.     

Engaging in imagery versus verbal processing of worry: Impact on negative intrusions in high worriers

Chronic, excessive, and uncontrollable worry is the defining characteristic of generalised anxiety disorder. Worry largely consists of verbal thought and it has been postulated that this predominance of verbal thought in worry may contribute to its perseveration. In an investigation of this issue, high worriers were trained to engage in either imagery or verbal processing. Mentation was sampled before and after a five-minute period of worry during which participants engaged in either imagery of the worry topic or verbal processing of the worry topic. Verbal worry resulted in a significant increase in negative intrusions, consistent with previous research. Furthermore, imagery was associated with a decrease in negative intrusions. The results support the theory that the predominantly verbal nature of worry may be responsible for the uncontrollability and maintenance of worry.
