The Portuguese version of Addenbrooke’s Cognitive Examination–Revised (ACE-R) in the diagnosis of subcortical vascular dementia and Alzheimer’s disease

The aim of this study was to investigate the accuracy of the Portuguese version of Addenbrooke’s Cognitive Examination–Revised (ACE-R) in detecting and differentiating early stage subcortical vascular dementia (SVD) from early stage Alzheimer’s disease (AD). Ninety-two subjects (18 SVD patients, 36 AD patients, and 38 healthy controls) were assessed using the ACE-R. Between-group’s differences were evaluated using the Quade’s rank analysis of covariance. The diagnostic accuracy and discriminatory ability of the ACE-R were examined via receiver operating characteristic (ROC) analysis. The ACE-R was able to successfully discriminate between patients and healthy subjects. The mean ACE-R total scores differed between SVD and AD patients; there were also significant differences in attention and orientation and in memory measures between the groups. An optimal cut-off of 72/73 was found for the detection of AD (sensitivity: 97%; specificity: 92%) and SVD (sensitivity: 100%; specificity: 92%).

Conflicts with Friends: A Multiplex View of Friendship and Conflict and Its Association with Performance in Teams

Drawing on conservation of resources theory, multiplex social networks research, and the emerging conflict involvement perspective, the purpose of this study is to develop and test a multiplex view of conflict that explicitly accounts for the nature of the social relationships between those involved in intrateam conflict and how these multiplex relationships differentially impact team performance. Data were collected from 120 teams engaged in a 4-month business simulation. Relationship conflicts occurring among team members who are friends have a negative impact on team performance, whereas those occurring between non-friends have a positive impact on team performance. Although we also find non-friend task conflicts to be beneficial for team performance, friend task conflicts have no impact on team performance. This study highlights the dark side of workplace friendships and admonishes managers to pay close attention not only to conflicts among employees, but also to the relational closeness of those involved in conflict. The current study provides empirical support for the emerging conflict involvement perspective by explicitly assessing the number of individuals involved in conflict as well as the type of relationships between them. We also extend research on multiplex relationships from the individual to the team level of analysis. Finally, we respond to calls for studies of multiplexity that include both positive and negative relationships.     

Scrutinizing the Emotional Nature of Intuitive Coherence Judgments

Dual‐system models propose that cognitive processing can occur either intuitively or deliberately. Unlike deliberate decision strategies, intuitive ones are assumed to have an emotional component attached to the decision process. We tested if intuitive decisions are indeed accompanied by an emotional response while deliberate decisions are not. Specifically, we conducted a psychophysiological study in which participants were instructed to decide either intuitively or deliberately if three simultaneously presented words were semantically coherent or incoherent (triad task). The degree of emotionality of these two decision strategies (intuitive vs. deliberate) was compared using changes in electrodermal activity (EDA) and the reaction time (RT) effect of an affective priming paradigm as primary measurements. Based on a valence‐arousal model, our results revealed that intuitive and deliberate judgments do not differ as to their emotional valence but that they do differ in emotional arousal. Most notably, sympathetic activation during intuitive judgments was significantly lower compared to sympathetic activation during deliberate judgments. Our results reflect that a relaxed state of mind—manifested in low sympathetic activity—could underlie the holistic processing that is assumed to facilitate the proliferation of semantic associations during coherence judgments. This suggests that coherence judgments made under an (instructed) intuitive decision mode have a specific psychophysiological signature and that arousal is the differentiating component between intuitive and deliberate decision strategies. © 2016 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd.     

Affective dimension in cognitive maps of Barcelona and São Paulo

This paper analyses the relationship between city and affection as revealed through an investigation into the feelings and emotions of a sample of inhabitants of Barcelona and São Paulo towards their cities. A study of affection in the context of a city has its origin in the assumption that it is possible to develop an ethical‐affective rationality in the creation of spaces of both public and private interest, a dimension that can serve to optimize the action of the inhabitants of a city. The theoretical/methodological approach adopted was essentially interdisciplinary, with a basis in social psychology, as can be seen in the data‐gathering instrument. In order to assess the city's affective dimension, individual interviews were carried out and a questionnaire was applied to individuals in groups. In the latter subjects were asked to make a drawing representing their city and to answer some questions regarding this pictorial representation. The sample consisted of 200 subjects, half of whom were from Barcelona and half from São Paulo. Most were in the age range 18–35, undergraduate or graduate students, with females and residents of the metropolitan areas of the two cities studied being in the majority. The qualitative data were classified according to their meaning and content, using the categories that had been established in the pilot study, namely contrasts, insecurity, pleasantness, and belonging. A statistical analysis was then performed on the resulting categories. After being categorized, catalogued, and qualified by metaphors, the responses gave the following images: city of contrast, city of attraction, city of destruction, city of surprises, city of movement, and pleasant city. These images show feelings and emotions about Barcelona and São Paulo that act as representations. This presents the need to revise the affective dimension in the meaning structure of cognitive maps as proposed by Lynch. As a result, the new category of affective maps is therefore proposed, as being the category that expresses affective meanings and serves as an indication of the level of esteem for the city, two aspects that act as reference points for the involvement and participation of a city's inhabitants.     

The processing of two-digit numbers in bilinguals

We explored possible between-language influences when bilinguals processed two-digit numbers. Spanish/English bilinguals and German/English bilinguals performed a number comparison task with Arabic digits and verbal numbers in their first language (L1) and second language (L2) while the unit-decade compatibility was manipulated. The two bilingual groups showed regular compatibility effect with Arabic digits. In L1, Spanish/English bilinguals showed reverse compatibility effect, while German/English bilinguals showed regular compatibility effect. However, both groups of bilinguals presented reverse compatibility effect in English (L2), which suggested that the bilinguals' L1 did not determine the processing of number words in their L2. The results indicated that bilinguals processed two-digit number words selectively in their L1 and L2 and that they did not transcode L2 numbers into Arabic format.
