Quality of Life in the European Union and the United States of America: Evidence from Comprehensive Indices

The main question of this article is about the quality of life in the European Union and the United States measured by different comprehensive indicators (HDI, WBI, WISP, OLS, PWI, ABS, HLE). On the world scale moderately different levels of quality of life characterize the European Area and the US. In objective terms, the US is more at the top level regarding economy and science, whereas Europe is more at the top level regarding social concerns in a broad sense. In subjective terms, which means to rely on the usual subjective measures, the average of US population seems to be slightly better off than the average of the EU population. That said, the differences inside the EU are often more significant than those between the EU and the US. Many EU countries in Northern and Western Europe show higher satisfaction levels than the US, and Eastern Europe is especially low in respect to the satisfaction of its population. It is rather obvious that the choice of criteria and values influences the results of the comparisons of nations and supranational unions to a considerable degree.     

Spontaneously occurring images and early memories in people with body dysmorphic disorder

A semi‐structured interview assessing the presence and characteristics of spontaneous appearance‐related images was designed and administered. A total of 18 patients with body dysmorphic disorder (BDD) and 18 normal controls took part. The BDD patients were found to have spontaneously occurring appearance‐related images that were significantly more negative, recurrent, and viewed from an observer perspective than control participants. These images were more vivid and detailed and typically involved visual and organic (internal body) sensations. The study also found that BDD images were linked to early stressful memories, and that images were more likely than verbal thoughts to be linked to these memories. Implications for theory and clinical practice are discussed.     

Changing the working self alters the emotions prompted by recall

Results from three studies indicated that emotional responses to memories can be changed by altering the working self. In particular, these results showed that emotional reactions to memories: (1) were especially positive when memories were perceived to be central to the working self (Experiment 1); (2) were muted when the working self was changed by adopting a third-person perspective during recall (Experiment 1); (3) of an event in the life of each participant's mother weakened when an individual was induced to experience a self that felt less close to their mother (Experiment 2) and (4) of a childhood event provoked especially positive emotional reactions after exposure to a mortality salience manipulation that increased perceived self-worth (Experiment 3). The extent to which mother was included in the self (Experiment 2) and self-worth (Experiment 3) plausibly mediated the effects of the manipulations on participants' emotional reactions to recalled events.     

Unravelling the motivational yarn: A framework for understanding the instigation of implicitly motivated behaviour resulting from deprivation and positive affect

Research suggests that the motivation to perform specific behaviours can originate in the unconscious. This implicit motivation can generally be traced to two basic sources: Deprivation of essential resources and positive affect attached to the specific behaviour. Yet, whereas previous research has increased our understanding of the emergence of implicit motivation, there is little theoretical analysis and empirical research that addresses how these sources interact in producing motivation. This chapter presents a framework for the comprehension of implicitly motivated behaviour resulting from deprivation and positive affect. The framework consists of two essential components. First, it proposes that mental representations of behaviour direct and prepare individuals to engage in behaviour. Second, it suggests that a reward signal either emanating from deprivation or positive affect acts upon behaviour representations to produce motivated behaviour. We present several findings supporting the framework and discuss these findings in the context of non-conscious goal pursuit and needs.     

Monaural Loudness Adaptation for Middle-Intensity Middle-Frequency Signals: The Importance of Measurement Technique

Using the Simple Adaptation technique (SA) and the Ipsilateral Comparison Paradigm (ICP), the authors studied monaural loudness adaptation to a middle-intensity [60 dB(A)] tone at signal frequencies of 250, 1000, and 4000 Hz in the left and right ears. Adaptation effects were absent when the SA procedure was used. However, they were observed uniformly across all frequency values with the ICP, a result that challenges the assertion in the literature, on the basis of SA measures, that loudness adaptation for middle-intensity signals occurs only at frequencies above 4000 Hz. The ICP features periodic intensity modulations (±10 dB relative to the base signal) to accommodate listeners' needs for referents by which they can gauge subtle changes in the loudness of the adapting tone, a key component that is missing in the SA method. Adaptation effects in this investigation were similar in both ears, supporting the equal susceptibility assumption common in loudness adaptation studies.     

Hedonic Intensity of Disappointment and Elation

This research is an investigation of the hedonic intensities of elation and disappointment following the outcomes of risky gambles using two principles: disappointment aversion and the principle of limited emotion processing. Disappointment aversion implies a stronger impact of disappointment compared with elation; the principle of limited emotion processing predicts a smaller impact of elation if it occurs with a real gain, and a smaller impact of disappointment if it occurs with a real loss. Both principles support each other in the gain domain but operate against each other in the loss domain. It was predicted that disappointment would outweigh elation in the gain domain. For the loss domain, this question was left open to empirical scrutiny. Participants were provided with hypothetical gambles and were required to imagine having won, not won, lost, or not lost, money. Results supported the prediction for the gain domain; mixed results emerged for the loss domain. The model adds to the understanding of the cognitive and emotional processes following the outcomes of risky events.     

Anxiety sensitivity and intolerance of uncertainty: Evidence of incremental specificity in relation to health anxiety

Anxiety sensitivity (AS) reflects the fear of arousal-related sensations and intolerance of uncertainty (IU) represents the dispositional fear of the unknown. Within cognitive–behavioral models, AS and IU are individual difference variables considered central to the phenomenology of health anxiety. However, prior studies have cast doubt on whether both variables incrementally contribute to our understanding of health anxiety. Addressing limitations of these prior studies, the present study examined the incremental specificity of AS and IU as these two variables relate to health anxiety in a large medically healthy sample of community adults (N = 474). Both AS and IU incrementally contributed to the concurrent prediction of health anxiety beyond both negative affect and one another. However, within these analyses, the physical dimension of AS and the inhibitory dimension of IU were the only AS and IU dimensions to evidence incremental specificity in relation to health anxiety.
