The rhythm of melatonin synthesis in the epiphysis and its control by light

The paper deals with the central regulation of the circadian rhythm of the melatonin in the pineal gland by light according to the literature. Examples of the effects of melatonin and their inclusion in the total endocrine complexity are pointed out. Possibilities for a therapy of chronobiological diseases with bright light resulting from animal experiments are discussed in connection with requirements for a future application to the therapy of human beings.     

A cautionary note on the use of probability values to evaluate interobserver agreement

Proposed methods of assessing the statistical significance of interobserver agreements provide erroneous probability values when conducted on serially correlated data. Investigators who wish to evaluate interobserver agreements by means of statistical significance can do so by limiting the analysis to every k(th) interval of data, or by using Markovian techniques which accommodate serial correlations.     

Elevation in Response to Entertainment Portrayals of Moral Virtue

Media psychologists have long puzzled over how individuals can experience enjoyment from entertainment such as tragedies that often elicit profound feelings of sadness. The present research examines the idea that a focus on “meaningful” entertainment and affective responses identified as “elevation” may provide a framework for understanding many examples of sad or dramatic entertainment. The results of this study suggest that many types of meaningful cinematic entertainment feature portrayals of moral virtues (e.g., altruism). These portrayals, in turn, elicit feelings of elevation (e.g., inspiration) that are signified in terms of mixed affect and unique physical responses (e.g., lump in throat). Ultimately, elevation also gives rise to motivations to embody moral virtues, such as being a better person or helping others.     

Body Covering and Body Image: A Comparison of Veiled and Unveiled Muslim Women,Christian Women,and Atheist Women Regarding Body Checking,Body Dissatisfaction,and Eating Disorder Symptoms

Although Islam is the fastest growing religion worldwide, only few studies have investigated body image in Muslim women, and no study has investigated body checking. Therefore, the present study examined whether body image, body checking, and disordered eating differ between veiled and unveiled Muslim women, Christian women, and atheist women. While the groups did not differ regarding body dissatisfaction, unveiled Muslim women reported more checking than veiled Muslim and Christian women, and higher bulimia scores than Christian. Thus, prevention against eating disorders should integrate all women, irrespective of religious affiliation or veiling, with a particular focus on unveiled Muslim women.     

Pupillary Stroop effects

We recorded the pupil diameters of participants performing the words’ color-naming Stroop task (i.e., naming the color of a word that names a color). Non-color words were used as baseline to firmly establish the effects of semantic relatedness induced by color word distractors. We replicated the classic Stroop effects of color congruency and color incongruency with pupillary diameter recordings: relative to non-color words, pupil diameters increased for color distractors that differed from color responses, while they reduced for color distractors that were identical to color responses. Analyses of the time courses of pupil responses revealed further differences between color-congruent and color-incongruent distractors, with the latter inducing a steep increase of pupil size and the former a relatively lower increase. Consistent with previous findings that have demonstrated that pupil size increases as task demands rise, the present results indicate that pupillometry is a robust measure of Stroop interference, and it represents a valuable addition to the cognitive scientist’s toolbox.     

Vulnerability schemas of individuals in couples relationships: a cognitive perspective

The professional literature has recently given attention to addressing individual schemas in couples relationships, with particular emphasis on the fact that individual vulnerability has a significant impact on couples relationships. This article addresses how this vulnerability can be restructured during the course of couples therapy. Case vignettes are used to illustrate how the model can be applied. Some of the implications of this model are considered in the discussion section.Authors note: Portions of this article were published in Norwegian by the first author and appear in Nordby, T.T.
