Effects of Personal Epistemology on the Understanding of Multiple Texts

We examined whether the text understanding of students holding naïve and sophisticated epistemological beliefs was differentially affected by text format, also controlling for effects of gender, word decoding, and prior knowledge on understanding. The participants were 39 Norwegian first-year teacher students, and the topic of reading was attention-deficit hyperactivity disorder (ADHD). It was found that only readers holding sophisticated epistemological beliefs displayed adequate understanding when reading multiple, partly conflicting, texts about ADHD, whereas students holding naïve epistemological beliefs gained better understanding when reading a single textbook-like source with identical content. This finding, however, depended on the level of understanding being measured by the criterial task, with only the task measuring deeper situational text understanding showing an interaction between epistemological beliefs and text format. This study provides evidence that not only knowledge itself, but also personal beliefs about knowledge, may enhance or constrain deeper understanding of multiple texts.     

Photographic Evidence and the Problem of Theory-Ladenness

Scientists use visualisations of different kinds in a variety of ways in their scientific work. In the following article, we will take a closer look at the use of photographic pictures as scientific evidence. In accordance with Patrick Maynard’s thesis, photography will be regarded as a family of technologies serving different purposes in divergent contexts. One of these is its ability to detect certain phenomena. Nonetheless, with regard to the philosophical thesis of theory-ladenness of observation, we encounter certain reservations concerning the status of photography and that of photographic pictures in the process of measurement in science. Accordingly, the aim of this paper is twofold: We will discuss suggested solutions both for the technological and for the psychological part of the problem of theory-ladenness appearing in the context of the use of photography in scientific observations. The essential proposal will be to follow Christian Suhm in his advice to make a distinction between theory-relativity and theory-ladenness.     

Sexual Abuse and the Christian Congregation: The Role of Gender in Pastoral Care for Victims

This study investigated the role of gender in the care for victims of sexual abuse within three Swedish Christian denominations. Questionnaires anchored by vignettes illustrating different abuse situations were answered by 421 clerics. The main findings were that female respondents apprehended the described situations as more likely to occur than male respondents did, and that levels of preparedness to offer pastoral care and belief in the likelihood of the situations to occur were higher when a female was the victim or a male was the perpetrator. Denominational differences were found concerning level of personal discomfort when hearing about the abuse.     

Migranten in sozial schwachen Stadtteilen von Berlin

Background

The aim of the present study was to compare psychological distress and substance use between migrant and non-migrant populations in a socially deprived area of Berlin.

Methods

A population-based random sample stratified for age (18?C57?years) and gender (50% female) was retrieved from the registration office. A total of 143 persons were included in the study. The participation rate was 48.5% when contact was established. Psychological distress was assessed using the General Health Questionnaire (GHQ-28) with its four subscales, somatic symptoms, anxiety/insomnia, social dysfunction and severe depression. Substance use was quantified using the Alcohol Use Identification Disorder Test (AUDIT) and the Fagerstr?m Test for Nicotine Dependence (FTND).

Results

Of the study population 51.3% were first or second generation migrants and lived more often in single households. Migrants had lower educational levels and lower employment rates. The mean scores of migrants and non-migrants did not differ on any of the subscales somatic symptoms, anxiety/depression, social dysfunction or severe depression of the GHQ-28. Non-migrants showed significantly higher risks regarding alcohol use.

Discussion

The present study did not reveal any differences regarding symptom profiles in the spectrum of anxiety and depression between non-migrants and migrants who lived in a socially deprived area. Migrants may compensate higher social risk profiles with lower risks regarding alcohol use. Larger samples have to inform on possible differences regarding smoking and other substances.     

Early drinking onset: A study of prevalence and determinants among 13‐year‐old adolescents in Norway

Early drinking onset is associated with different psychosocial adjustment problems among adolescents. The aim of this study was to assess determinants associated with early drinking and to identify factors predicting early drinking onset among adolescents. The study included 1,550 eighth‐graders with a mean age of 13.5 years from 41 schools. A total of 24% (boys 29%, girls 19%) had ever drunk alcohol, while 14% had drunk some alcohol in the last 30 days. Further, early drinking was associated with gender, religion, school performance, smoking and bullying in the bivariate tests. Predictors of early drinking onset were identified by generalized linear mixed models with two multivariable models created. The first model included social and environmental variables. Entering intentions, expectancies, attitudes and norms into the multivariable analysis resulted in a significant improvement of the model fit constituting 86% in the second model. The percentage correctly classified those (56%) who had been drinking in the second model which was two times higher compared to the first model. Gender, religion and smoking emerged as significant predictors of drinking in both models.     

Differences in top-down influences on the reversal rate of different categories of reversible figures

Understanding the mechanisms underlying the multistability of reversible figures may provide valuable insights into the normal functioning of our visual system. The proposed factors that control the perceptual alternations of reversible figures can be classified into bottom-up and top-down processes. In the present study, we report differences in top-down effects on the reversal rate depending on whether a structural perspective (Necker cube, Schr?der staircase) or a meaningful content (duck/rabbit figure, chef/dog figure) is subject to the reversal phenomenon. In order to activate top-down mechanisms explicitly the subjects had the instruction to bring the reversal rate under voluntary control. The results indicated that both slowing down and speeding up the rate of alternations was more effective for the content-reversal figures (duck/rabbit, chef/dog) than for the rather abstract perspective-reversal figures (Necker cube, Schr?der staircase). In order to investigate the effect of meaningfulness in figure/ground reversals, the effect of the same instructional variable was also determined for Rubin's vase/faces and the Maltese cross. The results showed a similar tendency as in the case of the comparison between perspective reversals and content reversals. Possible cognitive processes that may play a role in top-down influences on figure reversal and theoretical implications of these findings for the interaction of bottom-up and top-down processes are discussed.     

Moving to higher ground: The dynamic field theory and the dynamics of visual cognition

In the present report, we describe a new dynamic field theory that captures the dynamics of visuo-spatial cognition. This theory grew out of the dynamic systems approach to motor control and development, and is grounded in neural principles. The initial application of dynamic field theory to issues in visuo-spatial cognition extended concepts of the motor approach to decision making in a sensori-motor context, and, more recently, to the dynamics of spatial cognition. Here we extend these concepts still further to address topics in visual cognition, including visual working memory for non-spatial object properties, the processes that underlie change detection, and the ‘binding problem’ in vision. In each case, we demonstrate that the general principles of the dynamic field approach can unify findings in the literature and generate novel predictions. We contend that the application of these concepts to visual cognition avoids the pitfalls of reductionist approaches in cognitive science, and points toward a formal integration of brains, bodies, and behavior.     

Memory for Textual Conflicts Predicts Sourcing When Adolescents Read Multiple Expository Texts

This study investigated whether memory for conflicting information predicted mental representation of source-content links (i.e., who said what) in a sample of 86 Norwegian adolescent readers. Participants read four texts presenting conflicting claims about sun exposure and health. With differences in gender, prior knowledge, and interest controlled for, and with self-reported critical reading strategies also included in a multiple regression analysis, it was found that the better participants remembered that the texts presented conflicting claims on the issue, the more likely they were to include source-content links in their mental representations of the texts.
