Seeing why they cannot see: Understanding the syndrome and causes of posterior cortical atrophy

Posterior cortical atrophy (PCA) is a syndrome defined by focal neurodegeneration of the parietal, occipital, and occipito‐temporal cortices and associated with progressive dysfunction of visual processing, praxis, numeracy and reading. The condition is most commonly caused by (and viewed as an atypical presentation of) Alzheimer's disease, although can also be caused by other degenerative diseases. The current paper examines the relationship of PCA to other degenerative syndromes, and considers what comparisons of these syndromes and disease phenotypes can tell us about underlying disease mechanisms. The focus then turns to neuropsychological investigations of the cognitive basis of symptoms which, although unusual in the broader context of a dementia clinic, are particularly characteristic of the PCA syndrome, before exploring implications for clinical management and patient and carer support.     

Pilot Testing and Preliminary Psychometric Validation of the Polish Translation of the EORTC INFO25 Questionnaire

The quality of information that oncological patients receive from health care professionals is an underestimated issue in Poland and Eastern European countries. There is lack of sufficient data on this subject. The European Organization for Research and Treatment of Cancer (EORTC) supplies a new tool for measuring the quality of information provided to cancer patients. The purpose of the study is the translation into Polish, pilot testing and preliminary validation of the EORTC information module (INFO25). Following the EORTC translation procedures, forward and back translations of the questionnaire were performed (English?→?Polish, Polish?→?English). The intermediate version of the INFO25 was pilot-tested together with the general questionnaire of quality of life (EORTC QLQ-C30). Reliability, validity and known-group comparison tests were performed. A total of 21 patients with different cancer diagnoses were recruited into the study (7 women and 14 men; mean age of 60,2 years, age range 25–73 years). Apart from filling out the INFO25, patients were interviewed about the difficulties with answering every questionnaire item. Patients' comments were analyzed and minor language changes were made to the initial translation. The internal consistency of the INFO25 showed a reliability of 0,78. The final version of the Polish translation of the INFO25 module was obtained and approved by the EORTC Quality of Life Department. It can now be used in clinical setting and for scientific purposes.     

How does green suit me? Consumers mentally match perceived product attributes with their domain‐specific motives when making green purchase decisions

Nowadays, environment‐friendly products are widely accepted by society. However, market share of sustainable technologies demanding higher investments or behavioral changes is rather small, indicating that consumers seem to generally approve of sustainable products, but rarely perceive them as being compatible with their needs. The present research introduces a model emphasizing the importance of consumers perceiving the product as being suitable to match their motives relevant to the product domain. In investigating a sample of 531 car drivers, the hypothesized model was tested in the realm of a highly relevant sustainable product: electric vehicles (EVs). Findings based on structural equation modeling showed that participants' perceived matching with EV attributes was related to their domain‐specific motives (hedonic, freedom, ecological, and financial motives) and a global preference towards the product. Specific to sustainable products, ecological motives strongly influenced participants' matching processes by positively affecting perceived matching with all product attributes. Participants' purchase intentions, in turn, were strongly affected by their perceived matching of the product with their motives. The added value of the model with respect to self‐image theories and implications for sustainable product marketing are examined through discussion. Copyright © 2014 John Wiley & Sons, Ltd.

How does aging affect recognition-based inference? A hierarchical Bayesian modeling approach

The recognition heuristic (RH) is a simple strategy for probabilistic inference according to which recognized objects are judged to score higher on a criterion than unrecognized objects. In this article, a hierarchical Bayesian extension of the multinomial r-model is applied to measure use of the RH on the individual participant level and to re-evaluate differences between younger and older adults' strategy reliance across environments. Further, it is explored how individual r-model parameters relate to alternative measures of the use of recognition and other knowledge, such as adherence rates and indices from signal-detection theory (SDT). Both younger and older adults used the RH substantially more often in an environment with high than low recognition validity, reflecting adaptivity in strategy use across environments. In extension of previous analyses (based on adherence rates), hierarchical modeling revealed that in an environment with low recognition validity, (a) older adults had a stronger tendency than younger adults to rely on the RH and (b) variability in RH use between individuals was larger than in an environment with high recognition validity; variability did not differ between age groups. Further, the r-model parameters correlated moderately with an SDT measure expressing how well people can discriminate cases where the RH leads to a correct vs. incorrect inference; this suggests that the r-model and the SDT measures may offer complementary insights into the use of recognition in decision making. In conclusion, younger and older adults are largely adaptive in their application of the RH, but cognitive aging may be associated with an increased tendency to rely on this strategy.     

(How) does positive and negative extended cross‐group contact predict direct cross‐group contact and intergroup attitudes?

Knowing that fellow ingroup members have cross‐group contact can affect how people think, feel, and behave towards an out‐group. Previous research on extended contact focused almost exclusively on positive cross‐group interactions, neglecting the fact that extended contact can also be negative. In this contribution, we introduce negative extended contact and investigate how both forms of extended contact predict direct cross‐group contact and intergroup attitudes. In two cross‐sectional studies (N₁ = 286, N₂ = 237), we found evidence that positive and negative extended contact uniquely predict intergroup attitudes, and that direct cross‐group contact mediates this effect. In Study 2 , we also provide initial evidence that extended contact might either prepare for or impair direct contact by changing ingroup norms and intergroup self‐efficacy, which in turn influence feelings of intergroup anxiety.     

Daily Work Stress and Relationship Satisfaction: Detachment Affects Romantic Couples’ Interactions Quality

Psychologically detaching from work in the private setting is crucial to recover from work stress and promotes well-being. Moreover, broad evidence documents negative effects of stress on relationship quality. However, the interpersonal consequences of detachment have barely been studied. We seek to investigate, in daily life, whether and how detachment affects the interaction quality with the romantic partner. We propose that stress impedes detaching from work, and that detachment in turn, promotes individuals’ ability to engage in positive interactions at home, which increases individual and relational well-being. In a first experience sampling study, involving 106 dual-earner couples with young children, detachment mediated the association between work stress and not only the stressed individual’s, but also their partner’s relationship quality. However, positive (affectionate) behaviors did not play a significant role in this process. In a second experience sampling study, involving 53 dual-earner couples with preschool children, detachment was associated with more affectionate interactions, which in turn, predicted lower actor, but not partner evening strain. These results suggest that detachment from work not only affects the working individual’s, but also their close partner’s the perception of their interactions, showing that detachment plays an important mediating role in the stress spillover and crossover process. This emphasizes the relevance of addressing interpersonal processes in the association between detachment and well-being.     

Rasch analysis of a simplified Beck Depression Inventory

Depression is one of the most clinically relevant mood disorders, and many assessment instruments have been developed to measure it. Probably the most frequently used instrument is Beck’s Depression Inventory (BDI). The simplified BDI (BDI-S) is a more efficient version of the BDI that has been shown to be no less reliable or valid. As the BDI-S has not yet been subjected to rigorous tests of Item Response Theory, it is the aim of the present paper to conduct such an analysis using the Rasch model. This study subjected a simplified version of the BDI consisting of 20 items (BDI-S20) to a Rasch analysis in a sample of N = 5,035 participants. The scale, minus one misfitting item (BDI-S19), yielded a good approximation to Rasch assumptions. Moderate differential item functioning (DIF) was present. It is concluded that the BDI-S19 is an internally valid instrument for assessing depression, although some room for improvement exists.
