Losing more than gaining from overall stable prices: the differential perception of increasing versus decreasing prices made the Euro look like a price booster

The present research examined whether price trend misperceptions can be explained by the differential perception of increasing versus decreasing prices. We expected price increases (losses to consumers) to be perceived as being more intense than price decreases (gains to consumers) of the same magnitude. This tendency, in turn, should be positively associated with how people perceive the overall price trend. To test this reasoning, participants in the first two studies were asked to compare German Mark (DM) and Euro prices. First, participants received a menu containing 21 dishes with DM prices, and their price trend expectations were assessed. Then, participants indicated for each dish to what extent the price had changed. Finally, participants' overall price trend judgments were assessed. In both studies, results indicate that price trend judgments were biased toward rising prices. In addition, price increases were perceived as rising more than price decreases of the same magnitude were perceived as falling. This tendency was positively associated with overall price trend judgments, even after controlling for expectations. Study 3 was to replicate these findings in a different domain to demonstrate the general nature and impact of the hypothesized effect. Copyright © 2007 John Wiley & Sons, Ltd.     

Mortality of geriatric and younger patients with schizophrenia in the community

Little is known about the differences in mortality among non-institutionalized geriatric and younger patients with schizophrenia. In this study long-term mortality and suicidal behavior of all the geriatric (age > or = 65 years), middle-age (age 41-64 years), and young (age 15-40 years) subjects with schizophrenia living in a Chinese rural community were compared. A 10 year follow-up investigation among a 1994 cohort (n = 510) of patients with schizophrenia was conducted in Xinjin County, Chengdu, China. Compared with young subjects, geriatric subjects with schizophrenia were more likely to be female, have more previous physical illness, never accepted treatment, and practice religious (p < or = 0.01). There were no significant differences of suicide attempts among the three groups. Young subjects had a higher rate of suicide (1,033.8 per 100,000 person-years), and geriatric subjects had a higher rate of deaths due to other causes (accident and natural causes) (4,314.2 per 100,000 person-years). Standardized mortality ratios for both suicide and deaths due to other causes were highest in young subjects and the lowest in geriatric subjects. Patients with schizophrenia in all age groups had a marked increase in mortality and suicide. Specific intervention strategies for decreasing mortality and suicide should be developed for patients with schizophrenia in different age groups.     

Gender Role Self-Concept and Gender-Typed Communication Behavior in Mixed-Sex and Same-Sex Dyads

The focus of this study was the relation between both gender role self-concept and gender role attitudes with gender-related behavior of interacting partners. We observed gender-typed communication behaviors of mixed-sex and same-sex dyads and measured gender role self-concept and gender role attitudes. Thirty mixed-sex dyads, 19 women dyads, and 15 men dyads participated in a behavior observation study. The results revealed that the activation of gender role self-concept varies depending on the gender of the interacting people. Furthermore, we found that context and gender of the interacting persons moderated the relation between self-concept and behavior. Participants' gender role attitudes did not correlate with their own behaviors but did with their partners' behaviors.     

Psychoanalysis as a creative shaping process2

The author first explains the concepts of creativity, play and aesthetic experience. He then outlines the psychoanalytic process as a creative one that shapes reality. Making a link between psychoanalysis and the humanities, he demonstrates that creative play is a fundamental aspect of the human experience of reality. Aesthetic experiences during the psychoanalytic process are comparable to the play by which children structure their world and artists' activity in following their urge to shape. Furthermore it is shown that creative actualisation testifies to a quasi‐biological need for coherence and structure. Through modern hermeneutics, the truth claims of aesthetic shaping can be established in epistemological terms. The basic principles of hermeneutics‐historicity, linguisticity and communicative experience‐find their psychoanalytic counterparts in memory, representational shaping and transference‐countertransference. Psychoanalysis is demonstrated to be simultaneously a science and an art. On the basis of a case history, aesthetic experience is shown to constitute a specific and unique form of access to psychic reality. Aesthetic experience and creativity do not only aid recovery from ‘bad psychological states’, they are also indispensable for the entire understanding of internal and external reality. It is possible to develop this understanding through a creative psychoanalytic attitude.     

Nascent entrepreneurship and the developing individual: Early entrepreneurial competence in adolescence and venture creation success during the career

What predicts a person's venture creation success over the course of the career, such as making progress in the venture creation process and multiple successful venture creations? Applying a life span approach of human development, this study examined the effect of early entrepreneurial competence in adolescence, which was gathered retrospectively by means of the Life History Calendar method. Human and social capitals during the founding process were investigated as mediators between adolescent competence and performance. Findings were derived from regression analyses on the basis of prospective and retrospective data from two independent samples (N = 88 nascent founders; N = 148 founders). We found that early entrepreneurial competence in adolescence had a positive effect on making progress in the venture creation process. Nascent founders' current human and social capital also had a direct effect, but it did not mediate the effect of early competences. Finally, the data revealed that early entrepreneurial competence in adolescence positively predicted habitual entrepreneurship (multiple successful venture creations) exhibited over a longer period of the individual career (specifically, 18 years). In line with the results from prospective longitudinal studies on early precursors of entrepreneurship, our findings underscore the long neglected importance of adolescent development in the explanation of entrepreneurial performance during the subsequent working life.     

Responses of urban crows to con- and hetero-specific alarm calls in predator and non-predator zoo enclosures

Urban animals and birds in particular are able to cope with diverse novel threats in a city environment such as avoiding novel, unfamiliar predators. Predator avoidance often includes alarm signals that can be used also by hetero-specifics, which is mainly the case in mixed-species flocks. It can also occur when species do not form flocks but co-occur together. In this study we tested whether urban crows use alarm calls of conspecifics and hetero-specifics (jackdaws, Corvus monedula) differently in a predator and a non-predator context with partly novel and unfamiliar zoo animal species. Birds were tested at the Tiergarten Schönbrunn in the city of Vienna by playing back con- and hetero-specific alarm calls and control stimuli (great tit song and no stimuli) at predator (wolf, polar bear) and non-predator (eland antelope and cranes, peccaries) enclosures. We recorded responses of crows as the percentage of birds flying away after hearing the playback (out of those present before the playback) and as the number of vocalizations given by the present birds. A significantly higher percentage of crows flew away after hearing either con- or hetero-specific alarm calls, but it did not significantly differ between the predator and the non-predator context. Crows treated jackdaw calls just as crow calls, indicating that they make proper use of hetero-specific alarm calls. Responding similarly in both contexts may suggest that the crows were uncertain about the threat a particular zoo animal represents and were generally cautious. In the predator context, however, a high percentage of crows also flew away upon hearing the great tit control song which suggests that they may still evaluate those species which occasionally killed crows as more dangerous and respond to any conspicuous sound.     

Relaxation‐induced cortisol changes within lunch breaks – an experimental longitudinal worksite field study

The aim of the worksite study presented here is to elucidate the cortisol reducing impact of different ways of spending lunch breaks. With the help of the so‐called silent room cabin concept it was possible to induce a relaxation opportunity that provides visual and territorial privacy. In order to evaluate its proposed effects, 14 call centre agents were distributed to either 20 min progressive muscle relaxation (PMR) or small talk break group. Participants were analysed in a controlled trial for a period of 6 months (1 day each month with five daily measurements at awakening, awakening +30 min, start of lunch break, end of lunch break, and bedtime) using saliva cortisol measurements as a stress indicator. Results indicated that only the PMR break reduced awakening, lunchtime, and bedtime cortisol response. Although further intervention research is required, our results suggest that post‐lunch PMR may sustainably reduce participants' cortisol states in real worksite settings.     

Gender characteristics of cerebral hemodynamics during complex cognitive functioning

Functional Transcranial Doppler sonography (fTCD) has been applied to assess peak mean cerebral blood flow velocity (MFV) with a high temporal resolution during cognitive activation. Yet, little attention has been devoted to gender-related alterations of MFV, including spectral analysis. In healthy subjects, fTCD was used to investigate a series of cerebral hemodynamic parameters in the middle cerebral arteries (MCA) during the Trail Making Tests (TMT), a means of selective attention and complex cognitive functioning. In females, there was a frequency peak at 0.375 Hz in both MCA, and we observed a dynamic shift in hemispheric dominance during that condition. Further, after the start phase, there was an MFV decline during complex functioning for the entire sample. These novel results suggest condition-specific features of cerebral hemodynamics in females, and it adds to the notion that gender is a fundamental confounder of brain physiology.
