Targets of the memorized position and visual contexts]

The goal of this study was to determine whether a sensorimotor or cognitive encoding is used to encode a target position and save it into iconic memory. The methodology consisted of disrupting a manual aiming movement to a memorized visual target by displacing the visual field containing the target. The nature of the encoding was inferred from the nature and the size of the errors relative to a control. The target was presented either centrally or in the right periphery. Participants moved their hand from the left to the right of fixation. Black and white vertical stripes covered the whole visual field. The visual field was either stationary throughout the trial or was displaced to the right or left at the extinction of the target or at the start of the hand movement. In the latter case, the displacement of the visual field obviously could only be taken into account by the participant during the gesture. In this condition, our hypothesis was that the aiming error would follow the direction of visual field displacement. Results showed three major effects: (1) Vision of the hand during the gesture improved the final accuracy; (2) visual field displacement produced an underestimation of the target distance only when the hand was not visible during the gesture and was always in the same direction displacement; and (3) the effect of the stationary structured visual field on aiming precision when the hand was not visible depended on the distance to the target. These results suggest that a stationary structured visual field is used to support the memory of the target position. The structured visual field is more critical when the hand is not visible and when the target appears in peripheral rather than central vision. This suggests that aiming depends on memory of the relative peripheral position of the target (allocentric reference). However, in the present task, cognitive encoding does not maintain the "position" of the target in memory without reference to the environment. The systematic effect of the visual field displacement on the manual aiming suggests that the role of environmental reference frames in memory for position is not well understood. Some studies, in particular those of Giesbrecht and Dixon (1999) and Glover and Dixon (2001), suggested differing roles of the environment in the retention of the target position and the control of aiming movements toward the target. The present observations contribute to understanding the mechanism involved in locating and grasping objects with the hand.     

Does power corrupt? The moderating effect of status

Findings on the effect of power on corruption are mixed. To make sense of these mixed results, three studies were conducted to examine the moderating role of status on this effect. In Study 1, corrupt intent was measured using a corruption scenario that contained manipulations of power and status. In Study 2, corrupt behaviour was measured in a corruption game that contained manipulations of power and status. Study 3 was conducted in real organisational settings, and aimed to expand the external validity of Studies 1 and 2. The results of all three studies consistently indicated that the effect of power was moderated by status. Specifically, power increased corruption when status was low, whereas this effect disappeared when status was high. The implications of reducing the facilitating effect of power on corruption by considering status from the perspective of social hierarchy are discussed.     

Effects of telephone support on exercise capacity and quality of life in patients with chronic obstructive pulmonary disease: a meta-analysis

The aim of this meta-analysis was to evaluate the effects of disease education or pulmonary rehabilitation programs assisted with telephone support on physical capacity and quality of life (QOL) in chronic obstructive pulmonary disease (COPD) patients. A systematic search of PubMed, Embase, Web of Science and The Cochrane Library was conducted until May 2017. Randomized controlled trials (RCTs) examining the effects of telephone-assisted intervention versus a control group on exercise tolerance and QOL in patients with COPD were included. Two independent authors assessed the methodological quality of the trials using the Cochrane risk of bias tool. A meta-analysis was conducted with the Revman5.3 to quantify the effects of telephone-assisted interventions on walking capacity and QOL. In total, 10 studies involving 1037 participants were included. Due to the effect of telephone-assisted interventions, statistically significant results were found on Saint-George’s Respiratory Questionnaire (SGRQ) symptom scores [standard mean difference (SMD) ?.18, 95% confidence interval (CI) ?.33, ?.03, p-value .02)], SGRQ impact scores [SMD ?.35, 95% CI ?.60, ?.10, p-value .006)], SGRQ activity scores [SMD ?.30, 95% CI ?.45, ?.15, p-value < .0001)], SGRQ total score [SMD ?.36, 95% CI ?.51, ?.21, p-value < .00001)]. The effects on 6-min walk test (6MWT) and all Chronic Respiratory Questionnaire (CRQ) subscales were not significant (p > .05) based on the insufficient evidence. In conclusion, the role of telephone-assisted interventions in the management of COPD remains equivocal. Some encouraging results were seen with regard to SGRQ symptom, SGRQ impact, SGRQ activity and SGRQ total score. We believe that more methodologically rigorous large-scale randomized controlled trials are necessary to answer this study question.     

The use of religion in coping with grief among bereaved Malay Muslim parents

The purpose of this study is to explore the influence of religion on bereaved parents after the death of a child. Literature had attempted to understand how religiosity may influence parental grief both in positive and negative ways. However, this area is scarcely explored in the Malaysian context. This qualitative study involved 11 bereaved parents who lost their children due to accidents (n?=?9) and homicide (n?=?2). Open-ended questions that focused on the importance, activities, and role of religion in the grieving process among Malay parents were asked. According to the thematic analysis, some of the main themes found were that the bereaved parents described religion as a beneficial mechanism in helping them to adapt with their losses through various responses that indicated the perception that religion as a guidance. However, other than the positive impact, religiosity can also lead the bereaved parents to experience negative effects of using religion as a coping strategy. The influence of culture is prevalent in the current study as the theme of mystical belief and paranormal experiences were also reported. This study provides some professional implication from the possible use of religion in intervention.     

Treatment Effectiveness of PMTO for Children's Behavior Problems in Iceland: Child Outcomes in a Nationwide Randomized Controlled Trial

Well‐documented treatment methods must be tested following their implementation in community service agencies and across different cultures to ensure continuing effectiveness. This study was a randomized controlled trial (RCT) of Parent Management Training—the Oregon model (PMTO), conducted within a nationwide implementation in Iceland. Families of 102 clinically referred children with behavior problems were recruited from five municipalities throughout Iceland. Child age ranged from 5 to 12; 73% were boys. Families were randomly assigned to either PMTO or services usually offered in the communities (SAU). Child adjustment was measured with a latent construct based on parent, child, and teacher reports of externalizing and internalizing problems and social skills. Prepost intent‐to‐treat analyses showed that PMTO treatment led to greater reductions in child adjustment problems relative to the comparison group, obtaining a modest to medium effect size based on the construct score. Only one indicator (parent‐rated Social Skills) showed significant change independently and information on amount and kind of treatment in the SAU was limited. Overall, findings indicate that PMTO is an effective method to treat children's behavior problems in a Northern European culture and supply evidence for the method's successful implementation in community settings in Iceland. This is one of few nationwide implementation studies of PMTO outside the United States and the first RCT in Iceland to test a treatment model for children's behavior problems.     

Dissociative Experiences and Trauma Exposure Among Newly Arrived and Settled Young War Refugees

War-traumatized refugee adolescents are a vulnerable and understudied group. This study of two different groups of war-traumatized youth (N = 77) resettled in Sweden (newly arrived refugee adolescents, n = 42, 13–19 years, and settled students with childhood war experiences, n = 35, 11–18 years) evaluated their war experiences, refugee journey, general trauma exposure, posttraumatic stress symptoms, and dissociative experiences. Both groups had experienced many traumas and a substantial proportion reported levels consistent with posttraumatic stress (71% in the newly arrived group and 34% among the settled students) and dissociation (36% and 23%, respectively). The study also provides information about the type of adverse events experienced by war-refugee adolescents, including their own subjective appraisals of the worst events. The results show that the extent of trauma exposure and posttraumatic and dissociative symptomatology among refugee adolescents are considerable even after a period of resettlement, a finding that has educational, clinical, and social implications.     

Men's sense of humor and women's responses to courtship solicitations: an experimental field study

Producing humor might function as a fitness indicator associated with greater desirability during dating selection. A male confederate in a bar was instructed to tell (or not tell) funny jokes to two other male confederates. A few minutes later, when the second of two male confederates left, the first male confederate asked a female who was near his table and who had heard the funny jokes for her phone number. The previous expression of humor was associated with greater compliance with the male confederate's request and with a higher positive evaluation. The possible effects of humor are discussed from an evolutionary perspective.     

A Computationally Efficient State Space Approach to Estimating Multilevel Regression Models and Multilevel Confirmatory Factor Models

Although the state space approach for estimating multilevel regression models has been well established for decades in the time series literature, it does not receive much attention from educational and psychological researchers. In this article, we (a) introduce the state space approach for estimating multilevel regression models and (b) extend the state space approach for estimating multilevel factor models. A brief outline of the state space formulation is provided and then state space forms for univariate and multivariate multilevel regression models, and a multilevel confirmatory factor model, are illustrated. The utility of the state space approach is demonstrated with either a simulated or real example for each multilevel model. It is concluded that the results from the state space approach are essentially identical to those from specialized multilevel regression modeling and structural equation modeling software. More importantly, the state space approach offers researchers a computationally more efficient alternative to fit multilevel regression models with a large number of Level 1 units within each Level 2 unit or a large number of observations on each subject in a longitudinal study.     

Female Christ-figures in Films: A Feminist Critical Analysis of Breaking the Waves and Dead Man Walking

The discussion about the identity of the Christian ethics continue to be an important issue – not least in a Scandinavian context. In Denmark this is partly due to the legacy of K. E. Løgstrup. This question is also important in the light of the discussion about the relation between religion and politics. In the present article it is argued that a Lutheran attempt to keep religion and politics separate from each other is both a misreading of Luther and a highly problematic venture in a contemporary society. Further, the article discusses the problem of relating religion to politics with respect to potential conflicts. From an ecclesial perspective, it is then argued that religion and politics are inseparable and that this does not entail a dismissal of the common political discourse. Lastly, the article argues – from a Lutheran standpoint – for a possible understanding of the sources of public law as encompassing the unity and difference of religion and politics at one and the same time.     

The role of verbal memory in regressions during reading

During reading, participants generally move their eyes rightward on the line. A number of eye movements, called regressions, are made leftward, to words that have already been fixated. In the present study, we investigated the role of verbal memory during regressions. In Experiment 1, participants were asked to read sentences for comprehension. After reading, they were asked to make a regression to a target word presented auditorily. The results revealed that their regressions were guided by memory, as they differed from those of a control group who did not read the sentences. The role of verbal memory during regressions was then investigated by combining the reading task with articulatory suppression (Exps. 2 and 3). The results showed that articulatory suppression affected the size and the accuracy of the initial regression but had a minimal effect on corrective saccades. This suggests that verbal memory plays an important role in determining the location of the initial saccade during regressions.
