Stimulus-based lexical distinctiveness as a general word-recognition mechanism

Word recognition is generally assumed to be achieved via competition in the mental lexicon between phonetically similar word forms. However, this process has so far been examined only in the context of auditory phonetic similarity. In the present study, we investigated whether the influence of word-form similarity on word recognition holds in the visual modality and with the patterns of visual phonetic similarity. Deaf and hearing participants identified isolated spoken words presented visually on a video monitor. On the basis of computational modeling of the lexicon from visual confusion matrices of visual speech syllables, words were chosen to vary in visual phonetic distinctiveness, ranging from visually unambiguous (lexical equivalence class [LEC] size of 1) to highly confusable (LEC size greater than 10). Identification accuracy was found to be highly related to the word LEC size and frequency of occurrence in English. Deaf and hearing participants did not differ in their sensitivity to word LEC size and frequency. The results indicate that visual spoken word recognition shows strong similarities with its auditory counterpart in that the same dependencies on lexical similarity and word frequency are found to influence visual speech recognition accuracy. In particular, the results suggest that stimulus-based lexical distinctiveness is a valid construct to describe the underlying machinery of both visual and auditory spoken word recognition.     

The ingroup as pars pro toto: projection from the ingroup onto the inclusive category as a precursor to social discrimination

In an approach to intergroup discrimination and tolerance, it is assumed that the outgroup's difference from the ingroup is evaluated with reference to the prototype of the higher-order category that includes both groups. Two correlational studies yielded evidence that (a) group members tend to perceive their ingroup as relatively prototypical for the inclusive category (projection), (b) members highly identified with both ingroup and inclusive category (dual identity) tend to project most, and (c) relative prototypicality is related to negative attitudes toward the outgroup. The latter relation was further specified in Study 3, manipulating the valence of the inclusive category. Projection was related to more negative attitudes toward the outgroup when the inclusive category was primed positively but to more positive attitudes when it was primed negatively. The meaning of dual identities for intergroup relations is discussed.     

Self-perceived clinical competence,gender and workplace setting predict burnout among psychotherapists

Work-related stress, or burnout, is elevated among healthcare staff but the specific risk factors for psychotherapists are not clear, which makes it difficult to design interventions to target this population. Therefore, the aim of this study was to investigate a set of background variables and work-related risk factors for burnout among psychotherapists. Potential protective factors such as level of education, number of years in the profession and access to clinical supervision were investigated. Symptoms of burnout were measured with the Copenhagen Burnout Inventory, and data were collected from 327 psychotherapists. In this group, 62% reported moderate or high levels of burnout symptoms, with significantly higher levels of personal- and work-related burnout than client-related burnout. Being female, having low self-perceived competence and working in the public sector were associated with higher levels of burnout. Other factors, such as age, work experience, level of education or having clinical supervision, were not associated with burnout after controlling for gender, perceived competence and workplace setting. These results confirm previous research that underlines the importance of perceived competence and control over one's work environment, and that women are at higher risk of burnout, possibly because of factors outside of work. The importance of perceived competence as a protective factor suggests that methods that increase therapeutic competence may play an important role in countering work-related stress. In conclusion, there may be a need to continue to develop and integrate specific burnout prevention interventions for psychotherapists.     

A new semantical approach to the logic of preference

A possible world semantics for preference is developed. The remainder operator () is used to give precision to the notion that two states of the world are as similar as possible, given a specified difference between them. A general structure is introduced for preference relations between states of affairs, and three types of such preference relations are defined. It is argued that one of them, actual preference, corresponds closely to the concept of preference in informal discourse. Its logical properties are studied and shown to be plausible.     

Experiments: Why and How?

An experiment, in the standard scientific sense of the term, is a procedure in which some object of study is subjected to interventions (manipulations) that aim at obtaining a predictable outcome or at least predictable aspects of the outcome. The distinction between an experiment and a non-experimental observation is important since they are tailored to different epistemic needs. Experimentation has its origin in pre-scientific technological experiments that were undertaken in order to find the best technological means to achieve chosen ends. Important parts of the methodological arsenal of modern experimental science can be traced back to this pre-scientific, technological tradition. It is claimed that experimentation involves a unique combination of acting and observing, a combination whose unique epistemological properties have not yet been fully clarified.     

Subjective Wellbeing and Income: Empirical Patterns in the Rural Developing World

A commonality in the economics of happiness literature is that absolute income matters more for the subjective wellbeing of people at low income levels. In this article, we use a large sample of people in rural areas of developing countries with relatively low income levels to test whether subjective wellbeing an increasing function of absolute income in our sample, and to analyze the existence of adaptation and social comparison effects on subjective wellbeing. Our sample includes 6,973 rural households in 23 countries throughout Asia, Africa, and Latin America. The average total income per adult equivalent in our sample was US$ 1555, whereas levels of subjective wellbeing resembled levels found in previous research using cross-country data. We find that, despite low levels of absolute income, levels of subjective wellbeing of our respondents resemble levels found in previous research using cross-country data. We also find remarkable similarities in many of the determinants of subjective wellbeing previously tested. Our data show that absolute income covariates with subjective wellbeing, but—as for richer samples—the magnitude of the association is lower once we control for adaptation and social comparison. Finally, our results suggest that social comparison has a stronger effect than adaptation in explaining the subjective wellbeing of our sample. Our findings highlight the importance of adaptation and social comparison even at low levels of absolute income.     

Evidenz für psychodynamische Langzeittherapie

Despite continually increasing evidence for the effectiveness of psychodynamic psychotherapy in general, the empirical status of long-term psychodynamic psychotherapy (LTPP) remains controversial. Convincing outcome studies of LTPP were lacking for a long time. This article gives an overview of available systematic reviews addressing the evidence for LTPP. The findings suggest that LTPP can yield large and stable effects across a variety of diagnoses and particularly in complex mental disorders, which even tend to increase after termination of treatment. In comparison to other shorter or less intensive methods of psychotherapy, LTPP has proven to be significantly superior with respect to most outcome domains. First economic analyses suggest that LTPP may be cost-effective in the long run. The comparison of randomized controlled with observational studies revealed no significant differences in outcome; however, the evidence for LTPP is frequently challenged by proponents of other therapeutic approaches or scientific orientations. The criticisms were repeatedly answered and none of the concerns raised by critics identified an issue that would have affected the overall conclusions of the available reviews. Nevertheless, further studies are urgently required to broaden the evidence base for LTPP in order to allow more refined analyses addressing the effects of specific forms of LTPP both in specific disorders and in comparison to specific forms of alternative therapies.     

The role of objective health indicators and neuroticism in perceived health and psychological well-being among patients with chronic heart failure

A total of 119 clinically stable patients with symptomatic congestive heart failure (34 females, 85 males) were recruited from an outpatient hospital practice to explore the role of objective health indicators and neuroticism in subjective health (physical limitations) and psychological well-being. Patients were grouped according to the New York Heart Association functional class criteria (NYHA: indicator of functional status) and proatrial natriuretic factor (proANF), a cardiac hormone that maintains normal fluid balance and vascular resistance. Scores on these two objective indicators of disease severity were generally unrelated to psychological measures, whereas neuroticism scores (EPQ-N) were significantly correlated with indicators of subjective health (perceived disease-related physical limitations) and psychological well-being (depression, general life-satisfaction). Significant interactions between proANF and neuroticism appear due to low physical limitation score among subjects with elevated level of proANF and low scores on neuroticism. High physical limitation was reported by subjects with high level of proANF as well as high scores on neuroticism. Moreover, a marginal significant interaction between NYHA and EPQ-N scores in relation to severity of depression was detected by analyses from two-way ANOVA. Gender differences were due to higher proANF scores in males than females, whereas females scored higher than males on EPQ-N, perceived physical limitation and depression. Results from path analyses supported an indirect effect of neuroticism via perceived physical limitation for males. Possible mechanisms involved in these relations are discussed.
