  2. The free and cued selective reminding test for predicting progression to alzheimer's disease in patients with mild cognitive impairment: A prospective longitudinal study

    Lemos, Raquel; Maroco, João; Simões, Mário R.; Santiago, Beatriz; Tomás, José; Santana, Isabel
    Amnestic mild cognitive impairment (aMCI) patients carry a greater risk of conversion to Alzheimer's disease (AD). Therefore, the International Working Group (IWG) on AD aims to consider some cases of aMCI as symptomatic prodromal AD. The core diagnostic marker of AD is a significant and progressive memory deficit, and the Free and Cued Selective Reminding Test (FCSRT) was recommended by the IWG to test memory in cases of possible prodromal AD. This study aims to investigate whether the performance on the FCSRT would enhance the ability to predict conversion to AD in an aMCI group. A longitudinal study was conducted...

  3. The informative value of type of repetition: Perceptual and conceptual fluency influences on judgments of truth

    Silva, Rita Rocha da; Garcia-Marques, Teresa; Reber, Rolf
    We contrast the effects of conceptual and perceptual fluency resulting from repetition in the truth effect. In Experiment 1, participants judged either verbatim or paraphrased repetitions, which reduce perceptual similarity to original statements. Judgments were made either immediately after the first exposure to the statements or after one week. Illusions of truth emerged for both types of repetition, with delay reducing both effects. In Experiment 2, participants judged verbatim and paraphrased repetitions with either the same or a contradictory meaning of original statements. In immediate judgments, illusions of truth emerged for repetitions with the same meaning and illusions of falseness...

  4. Exogenous attention to fear: Differential behavioral and neural responses to snakes and spiders

    Soares, Sandra Cristina de Oliveira; Kessel, Dominique; Lorca, María Hernández; Rubio, María J. García; Rodrigues, Paulo; Gomes, Nuno; Carretié, Luis
    Research has consistently shown that threat stimuli automatically attract attention in order to activate the defensive response systems. Recent findings have provided evidence that snakes tuned the visual system of evolving primates for their astute detection, particularly under challenging perceptual conditions. The goal of the present study was to measure behavioral and electrophysiological indices of exogenous attention to snakes, compared with spiders - matched for rated fear levels but for which sources of natural selection are less well grounded, and to innocuous animals (birds), which were presented as distracters, while participants were engaged in a letter discrimination task. Duration of...

  5. Beware the serpent: The advantage of ecologically-relevant stimuli in accessing visual awareness

    Gomes, Nuno; Silva, Samuel; Silva, Carlos Fernandes da; Soares, Sandra Cristina de Oliveira
    Snakes and spiders constitute fear-relevant stimuli for humans, as many species have deleterious and even fatal effects. However, snakes provoked an older and thus stronger evolutionary pressure than spiders, shaping the vision of earliest primates toward preferential visual processing, mainly in the most complex perceptual conditions. To the best of our knowledge, no study has yet directly assessed the role of ecologically-relevant stimuli in preferentially accessing visual awareness. Using continuous flash suppression (CFS), the present study assessed the role of evolutionary pressure in gaining a preferential access to visual awareness. For this purpose, we measured the time needed for three...

  6. Denying psychological properties of girls and prostitutes

    Rubini, Monica; Roncarati, Alessandra; Ravenna, Marcella; Albarello, Flavia; Moscatelli, Silvia; Semin, Gün R.
    This study examines the negative stereotypes of the category of women and their subcategories through the language of insults. Participants produced a list of epithets induced by the same hypothetical scenario in which the protagonist was presented either as a 'prostitute' or as a 'girl' (i.e., nonprostitute). Findings showed that the prostitute was addressed with taboo-related insults exaggerating sexual behavior, whereas the girl was mainly given warnings and intellectual insults. The implications of these results are discussed in relation to the underlying processes.

  7. The Impact of body dissatisfaction on distressing sexual difficulties among men and women: The mediator role of cognitive distraction

    Carvalheira, Ana Alexandra; Godinho, Leonor Figueiredo; Costa, Pedro Alexandre
    Research has demonstrated a negative impact of cognitive distraction on sexual activity, and body dissatisfaction has been associated with less satisfying and fewer sexual activities. In the current study we examined the extent to which cognitive distraction, based on body appearance and sexual performance, mediated the impact of body dissatisfaction on sexual difficulties among women and men. A sample of 493 women (Mage = 30.61) and 595 men (Mage = 37.90) completed an online survey. Women reported significantly higher levels of distressing sexual difficulties, significantly more body dissatisfaction, and greater cognitive distraction based on appearance than men. In contrast, men reported higher cognitive distraction...

  8. Modern Families: Parenting desire, intention, and experience among portuguese lesbian, gay, and bisexual individuals.

    Costa, Pedro Alexandre; Bidell, Markus
    The aim of this study was to examine parenting desire, intention, and experience among a sample of lesbian, gay, and bisexual individuals (N = 568) from Portugal between the ages of 18 and 76 years. Approximately 7% (n = 38) reported having children, with the majority stating a biological kinship with their children primarily from previous heterosexual relationships. The central focus of the current study includes participants without children (n = 530), on average 12 years younger than those with children. Among this group, 65% stated a desire to have children and 56% stated the intention to have children in...

  9. Worries, coping strategies and well-being in adolescence: Highlights from HBSC study in Portugal

    Matos, Margarida Gaspar de; Camacho, Inês; Reis, Marta; Costa, Diogo; Galvão, Diana
    The aim of this study was to understand adolescents’ worries and the strategies used to face them, and what makes them feel good. In this study, 3869 adolescents participated, of which 46.8% boys, attending grades 8 and 10, mean age 14.7 years, SD = 1.18, included in the Portuguese Health Behaviour in School-Aged Children survey 2014. In the first quantitative study, simple descriptive analyses and chi-squares were carried out and a regression model associated the intensity and frequency of worries with a decrease in perceived well-being; in a second qualitative study, content analysis was carried out regarding open questions about types of worries and ways to cope with worries and...

  10. Longitudinal factor analysis of public expenditure composition and human development in Brazil after the 1988 constitution

    Sousa, Rossana Guerra de; Paulo, Edilson; Maroco, João
    The way public policies are managed in Brazil has changed since the 1988 Federal Constitution. This study aimed to identify how changes in the structure of public expenditure composition at Brazilian federal states influenced local human development in these states. The states’ public expenditures were categorized according to their nature as spending indices whereas human development was measured through a human development index (HD). To verify the relationships between these variables, an accounting-social theoretical model was created and estimated through latent growth modeling (LGM). The LGM measurement period comprised five administration cycles of the Brazilian states (1988–2011). Variables were measured on data of the second year of state...

  11. Validation of the psychometric properties of cognitive fusion questionnaire. A study of the factorial validity and factorial invariance of the measure among osteoarticular disease, diabetes mellitus, obesity, depressive disorder, and general populations

    Costa, Joana; Maroco, João; Pinto-Gouveia, José
    Background The cognitive fusion questionnaire (CFQ) is a self‐report questionnaire that assesses the extent to which individuals are psychologically entangled with, and dominated by the form–content of their thoughts. The aim of this study was to replicate the factor structure of CFQ in osteoarticular disease, diabetes mellitus, obesity, depressive disorder, and normative population. It further examined the factorial invariance of the CFQ across these 5 groups. Method Data from 299 participants (N General Population = 67, N Osteoarticular Disease = 73, N Diabetes Mellitus = 47, N Depressive Disorder = 45, and N Obesity = 60) were subjected to confirmatory factorial analysis (CFA) to replicate the structural...

  13. Seeing the conflict: An attentional account of reasoning errors

    Mata, André; Ferreira, Mário Augusto Boto; Voss, Andreas; Kollei, Tanja
    In judgment and reasoning, intuition and deliberation can agree on the same responses, or they can be in conflict and suggest different responses. Incorrect responses to conflict problems have traditionally been interpreted as a sign of faulty problem-solving—an inability to solve the conflict. However, such errors might emerge earlier, from insufficient attention to the conflict. To test this attentional hypothesis, we manipulated the conflict in reasoning problems and used eye-tracking to measure attention. Across several measures, correct responders paid more attention than incorrect responders to conflict problems, and they discriminated between conflict and no-conflict problems better than incorrect responders. These results are consistent with a two-stage account of reasoning, whereby sound problem solving...

  14. Factors affecting the well-being of adolescents living with unemployed parents in times of economic recession: Findings from the portuguese HBSC study

    Frasquilho, Diana; Matos, Margarida Gaspar de; Marques, Adilson; Gaspar, Tânia; Almeida, José Miguel Caldas de
    Objectives: Using a national representative sample of adolescents with unemployed parents, this study examined which factors (sociodemographic and of satisfaction with family life and peers) are related to the negative effect of parents' unemployment on emotional well-being. Study design: Cross-sectional survey study. Methods: Data on adolescents (14.1 ± 1.7 years old), with at least one parent unemployed (n ¼ 1311, 53.2% girls), was provided by the Portuguese Health Behaviour in School-aged Children study. Descriptive statistics and logistic regression analyses were performed. Results: A high proportion of adolescents reported being emotionally affected by father's unemployment but not by their mother's. Older boys and older girls were more likely to report that...

  15. Smoking is unrelated to female sexual function

    Costa, Rui Miguel; Peres, Luís
    Background. Previous research shows that smoking status is unrelated to female sexual difficulties. However, degree of nicotine dependence has not been measured, and the assessment of sexual functioning has not specified penile–vaginal intercourse (henceforth, intercourse), which is more clearly impaired by sexual difficulties than other sexual behaviors. Objectives. To test if smoking status is associated with poorer female sexual function during intercourse, and if nicotine dependence rather than smoking status is related to poorer female sexual function. Methods. During 2012, 129 Portuguese community women reported their smoking status, and completed the Fagerstr¨om Test for Nicotine Dependence, the Female Sexual Function Index (FSFI), and an adaptation of the FSFI to assess sexual functioning specifically during intercourse,...

  16. Practicing ethnography in migration-related detention centers: A reflexive account

    Esposito, Francesca
    Feminist scholars, as well as community psychologists, have advocated the role of reflexive engagement in the research process in order to challenge power relations. Moreover, the liberating potential of storytelling, especially when working with issues of diversity and marginalization, has been stressed. The purpose of this article is to reflect on an ethnographic work underway in the Identification and Expulsion Center-CIE of Ponte Galeria, Rome. How the researcher's identities, values, and experiences, alongside power and privilege, have influenced her positioning in the research setting and the relationships formed with the different setting members is the subject of discussion. In sharing...

  17. Cross-cultural measurement invariance of adolescent self-report on the pediatric quality of life inventory™ 4.0

    Stevanovic, Dejan; Atilola, Olayinka; Vostanis, Panos; Balhara, Yatan Pal Singh; Avicenna, Mohamad; Kandemir, Hasan; Knez, Rajna; Franic, Tomislav; Petrov, Petar; Maroco, João; Supic, Zorica Terzic; Bagheri, Zahra
    This study evaluated the cross-cultural measurement invariance of the Pediatric Quality of Life Inventory version 4.0 (PedsQLTM) among adolescents sampled from Bulgaria, Croatia, India, Indonesia, Nigeria, Serbia, and Turkey. The multiple-indicator multiple-cause (MIMIC) model was used, which allowed controlling of demographic variables (i.e., age, gender, and socioeconomic status). Significant effects of country on scores within the PedsQLTM domains were observed, with up to 17 items showing differential item functioning (DIF) across the countries. We did not find support for cross-cultural measurement invariance hypotheses for scores on the PedsQLTM adolescent self-report in this study. Researchers should use caution in making cross-cultural quality of life comparisons while using...

  18. Leadership as an emergent feature in social organizations: Insights from a laboratory simulation experiment

    Curral, Luís A.; Silva, Pedro Marques-Quinteiro Fernandes da; Gomes, Catarina; Lind, Pedro G.
    Recent theoretical contributions have suggested a theory of leadership that is grounded in complexity theory, hence regarding leadership as a complex process (i.e., nonlinear; emergent). This article tests if complexity leadership theory promotes efficiency in work groups. 40 groups of five participants each had to complete four decision making tasks using the city simulation game SimCity4. Before engaging in the four decision making tasks, participants received information regarding what sort of leadership behaviors were more adequate to help them perform better. Results suggest that if complexity leadership theory is applied, groups can achieve higher efficiency over time, when compared with...

  19. Work-related activities that may contribute to musculoskeletal symptoms among dental students: Validation study

    Garcia, Patrícia Petromilli Nordi Sasso; Presoto, Cristina Dupim; Maroco, João; Campos, Juliana Alvares Duarte Bonini
    Background: Dentists are exposed to occupational hazards, such as musculoskeletal disorders, in which symptoms can manifest early in clinical practice. Objectives: To estimate the reliability and validity of the Portuguese version of the “Questionnaire on work-related activities that may contribute to musculoskeletal symptoms” when applied to dental students. Methods: 553 Brazilian students participated in the study. The one-factor structure originally proposed was tested through confirmatory factor analysis (CFA) using the indexes c2/df, CFI, GFI, and RMSEA. After observing an inadequate good fit (c2/df=7.140, CFI=0.791, GFI=0.778, RMSEA=0.129), the sample was subdivided into 3 groups and an exploratory factor analysis was conducted (EFA) (n=255). A CFA was then...

  20. Impact of sociodemographic characteristics, nutritional status and perceived stress in body weight concern of female college students

    Dias, Juliana Chioda Ribeiro; Silva, Wanderson Roberto da; Maroco, João; Campos, Juliana Alvares Duarte Bonini
    Aim: to estimate the contribution of nutritional status, perceived stress and sociodemographic variables in college students’ body weight concern. Method: participated 850 Brazilian students of one public university. Information such as age, area of study and schedule of the undergraduate course, body weight and height, economic status, household’s education level, household, studies funding and medication intake due to studies and labour activity were collected. Perceived stress and body weight concern were assessed, respectively, with the Portuguese versions of the Perceived Stress Scale (PSS) and the Weight Concerns Scale (WCS). The impact of several variables on body weight concern was verified...
