Visual adaptation to thin and fat bodies transfers across identity

Visual perception is highly variable and can be influenced by the surrounding world. Previous research has revealed that body perception can be biased due to adaptation to thin or fat body shapes. The aim of the present study was to show that adaptation to certain body shapes and the resulting perceptual biases transfer across different identities of adaptation and test stimuli. We designed two similar adaptation experiments in which healthy female participants adapted to pictures of either thin or fat bodies and subsequently compared more or less distorted pictures of their own body to their actual body shape. In the first experiment (n = 16) the same identity was used as adaptation and test stimuli (i.e. pictures of the participant’s own body) while in the second experiment (n = 16) we used pictures of unfamiliar thin or fat bodies as adaptation stimuli. We found comparable adaptation effects in both experiments: After adaptation to a thin body, participants rated a thinner than actual body picture to be the most realistic and vice versa. We therefore assume that adaptation to certain body shapes transfers across different identities. These results raise the questions of whether some type of natural adaptation occurs in everyday life. Natural and predominant exposure to certain bodily features like body shape – especially the thin ideal in Western societies – could bias perception for these features. In this regard, further research might shed light on aspects of body dissatisfaction and the development of body image disturbances in terms of eating disorders

Chapter 10 - The Path to Present-Day Libraries

Elementary Education in Finland and the United States

Education is a part of society that affects everyone; it has to thrive in order for future generations to succeed in taking our place. For this reason, it is often debated how to best construct an education system that will be most effective. Through this debate comes the need for reform to morph education systems to fit the changing times and the fluctuating educational needs produced by the progression of time. By identifying Finland as a leading nation in the education world and as something to strive for, we can compare it to the underperforming education system of the United States to explore where the differences lie and how they impact student success rates as shown on the Programme for International Student Assessment. Before diving into educational variations, we look first at a whole picture view of the two countries to gain an idea of the societal context in which to analyze the dissimilarities in their education systems, as well as a background of the ideological fundamentals that form the foundation of their school structures. After gaining a deeper understanding of the social features and common beliefs surrounding education, the reform movements and current education systems of the two countries will be compared side by side, leading up to the identification of areas of Finnish success that can be modified to meet the needs of the United States

Monte Carlo Simulations of Star Clusters - IV. Calibration of the Monte Carlo Code and Comparison with Observations for the Open Cluster M67

We outline the steps needed in order to incorporate the evolution of single and binary stars into a particular Monte Carlo code for the dynamical evolution of a star cluster. We calibrate the results against N-body simulations, and present models for the evolution of the old open cluster M67 (which has been studied thoroughly in the literature with N-body techniques). The calibration is done by choosing appropriate free code parameters. We describe in particular the evolution of the binary, white dwarf and blue straggler populations, though not all channels for blue straggler formation are represented yet in our simulations. Calibrated Monte Carlo runs show good agreement with results of N-body simulations not only for global cluster parameters, but also for e.g. binary fraction, luminosity function and surface brightness. Comparison of Monte Carlo simulations with observational data for M67 shows that is possible to get reasonably good agreement between them. Unfortunately, because of the large statistical fluctuations of the numerical data and uncertainties in the observational data the inferred conclusions about the cluster initial conditions are not firm.Comment: 15 pages, 24 figure

Star Clusters

This review concentrates almost entirely on globular star clusters. It emphasises the increasing realisation that few of the traditional problems of star cluster astronomy can be studied in isolation: the influence of the Galaxy affects dynamical evolution deep in the core, and the spectrum of stellar masses; in turn the evolution of the core determines the highest stellar densities, and the rate of encounters. In this way external tidal effects indirectly influence the formation and evolution of blue stragglers, binary pulsars, X-ray sources, etc. More controversially, the stellar density appears to influence the relative distribution of normal stars. In the opposite sense, the evolution of individual stars governs much of the early dynamics of a globular cluster, and the existence of large numbers of primordial binary stars has changed important details of our picture of the dynamical evolution. New computational tools which will become available in the next few years will help dynamical theorists to address these questions.Comment: 10 pages, 3 figures, Te

The Impact of Shame, Self-Criticism and Social Rank on Eating Behaviours in Overweight and Obese Women Participating in a Weight Management Programme

Recent research has suggested that obesity is a stigmatised condition. Concerns with personal inferiority (social rank), shame and self-criticism may impact on weight management behaviours. The current study examined associations between social comparison (shame, self-criticism), negative affect and eating behaviours in women attending a community based weight management programme focused on behaviour change. 2,236 participants of the programme completed an online survey using measures of shame, self-criticism, social comparison, and weight-related affect, which were adapted to specifically address eating behaviour, weight and body shape perceptions. Correlation analyses showed that shame, self-criticism and social comparison were associated with negative affect. All of these variables were related to eating regulation and weight control (p < 0.001). Path analysis revealed that the association of shame, hated-self, and low self-reassurance on disinhibition and susceptibility to hunger was fully mediated by weight-related negative affect, even when controlling for the effect of depressive symptoms (p < 0.050 to p < 0.010). In addition, feelings of inadequacy and unfavourable social comparisons were associated with higher disinhibition and susceptibility to hunger, partially mediated through weight-related negative affect (p = 0.001). These variables were negatively associated with extent of weight loss during programme attendance prior to the survey, while self-reassurance and positive social comparisons were positively associated with the extent of weight loss prior to the survey (p < .050). Shame, self-criticism, and perceptions of inferiority may play a significant role in self-regulation of eating behaviour in overweight people trying to manage their weight

Memories of shame experiences with others and depression symptoms: the mediating role of experiential avoidance

Background: Shame experiences have been suggested to be related with psychopathological symptoms and with self-relevant beliefs. Recent studies also suggest that avoidant-focused strategies (e.g., rumination, thought suppression and dissociation) mediate the impact of shame memories and depression symptoms. However, experiential avoidance has been found to mediate the relation between early experience of abuse and psychopathological symptoms. Our goal was to test the mediating effect of experiential avoidance in the relation between both the nature of shame experiences at the hands of caregivers and the centrality of shame memories with others, and depression symptoms. Method: Using structural equation modelling, we assessed the frequency and nature of recalled shame experiences at the hands of caregivers, the centrality of shame experiences with others throughout childhood and adolescence, experiential avoidance and depression symptomatology in 161 participants from general population. Results: Experiential avoidance mediates the impact of shame experiences with caregivers and depression symptoms. Experiential avoidance also mediated the association between the centrality of shame experiences with others and depression symptoms. Conclusion: Our results suggest that shame memories with others do not per se impact on depression symptoms, but rather the unwillingness to experience them and the attempts to control them. Hence, our results emphasize the importance of addressing affect regulation processes such as avoidance when dealing with shame memories, particularly with patients who experience depression symptoms
