Item Adaptive Non-Immersive VR Environment for Eliciting Fear of Cockroaches : a Physiology-Driven Approach Combined with 3D-TV Exposure(International Journal of Psychological Research, 2020) Rosa, Pedro Joel; Luz, FIlipe Costa; Junior, Roberto; Oliveira, Jorge; Morais, Diogo; Gamito, PedroNon-immersive VR environments are related to the least interactive application of VR techniques, such that interaction with the VR environment can occur commonly by 3D-TV without full immersion into the environment. This study presents how 3D-TV exposure combined with physiology recording can elicit fear of cockroaches among individuals with different levels of fear. Thirty-six participants, set apart into three fear groups (low vs. moderate vs. high), were exposed to VR environment with cockroaches for 4 minutes while recording and using cardiac activity as input to the VR environment. Results revealed significant effects on self-report measures and heart rate between different fear groups. Moreover, participants with higher levels of fear were more likely to trigger cockroaches into the scenario due to their cardiac acceleration. Overall results suggest that our physiology-driven VR environment is valid for fear elicitation while having potential use in therapeutic domain.Item Aggressive communication style as predictor of cyberbullying, emotional wellbeing, and personal moral beliefs in adolescence(2021) Pereira, Nádia Margarida Salgado; Ferreira, Paula Alexandra Nunes da Costa; Simão, Ana Margarida Vieira da Veiga; Paulino, Ana Paula Oliveira; Oliveira, Sofia; Mora Merchan, Joaquin A.Different forms of verbal aggression are often presented in cyberbullying and are used to harm others in online communication. This study proposed to understand the influence of an aggressive communication style on adolescents’ intentions to engage in cyberbullying, their emotional well-being, and personal moral beliefs. A convenience sample of 218 adolescents (Mage = 14.67, SD = 0.84, 53% girls) in Portugal responded to questionnaires. Structural equation modeling analyses were conducted to test mediating effects. An aggressive communication style may lead adolescents to perceive cyberbullying behavior as fair, and to decrease their emotional well-being. Moreover, this communication style may contribute to adolescents’ intentions to engage in cyberbullying, and whether they believe this type of behavior is fair or unfair may determine those intentions. These findings contribute to an understanding of determiners of cyberbullying and the provision of insights to develop school interventions in this field.Item Assessing the Unidimensionality of Clayton’s Environmental Identity Scale Using Confirmatory Factor Analysis (CFA) and Bifactor Exploratory Structural Equation Modeling (bifactor-ESEM)(University of California Press, 2021) Moreira, Paulo; Loureiro, Ana Luisa Cardoso Marques Teixeira; Inman, Richard; Olivos-Jara, PabloA relevant intrapersonal characteristic for understanding intentions and behavior toward environmental sustainability is the degree to which nature is important for a person’s self-definition. Clayton’s Environmental Identity (EID) scale purports to measure this construct. However, a limited number of prior exploratory studies of this measure have supported different factor structures. Hence, our initial aim was to develop an understanding of the dimensionality of Clayton’s 24-item EID scale by testing competing latent structures using confirmatory factor analysis. We analyzed self-reported data from 458 adults (Mage = 26.7 years; 81% female). Four a priori models (a first-order model, a second-order model, a unidimensional model, and a bifactor model) did not show satisfactory fit to the data. An ancillary analysis using bifactor exploratory structural equation modeling (bifactor-ESEM) indicated a bifactor model with three specific factors had a good fit to the data. The factor loadings of this model and values for bifactor indices (Omega Hierarchical and Explained Common Variance [ECV]) indicated a single mean score across all EID scale items taps into an essentially unidimensional construct and is therefore appropriate to interpret. In sum, our study provides a critical insight into the dimensionality of Clayton’s EID scale that will be valuable when applying this measure for research and intervention purposes.Item Attitudes of Police Recruits Toward Offenders: The Impact of the Police Training on Attitudinal Change(2021-10-06) Cunha, Olga Cecília Soares da; Carvalho, Filipa; Rodrigues, Andreia de Castro; Gonçalves, Rui Abrunhosa; Cruz, Ana Rita Pereira daThe traditional prevailing perspectives on attitudes assume that attitudes, once formed, are relatively stable over time. However, research has revealed that attitudes may be influenced by different factors that may contribute to change them. The present longitudinal study aims to understand if the police recruits’ attitudes towards offenders change after police training. Besides, we aim to understand the impact of sociodemographic and personality variables on recruits’ attitudes towards offenders and which variables predict recruits’ attitudes. The Attitude Scale towards Offenders (ATO) and the NEO-FFI Personality Inventory were used in a sample of 74 recruits of a Portuguese Police Force - Guarda Nacional Republicana -, in two distinct moments (at the beginning and at the end of the police training programme). Results revealed that at the end of the training recruits hold more negative attitudes towards offenders. Those who had previous professional experience in the army hold more positive attitudes, but only at the beginning of the training. Only attitudes towards offenders at the beginning of the police training predict recruits’ attitudes towards offenders at the end of the training. These results emphasize the importance of initial and continuous training of recruits and police officers, especially in terms of their attitudes towards offenders.Item Buss-Perry Aggression Questionnaire: Factor Structure and Measurement Invariance among Portuguese Male Perpetrators of Intimate Partner Violence(2021) Cunha, Olga Cecília Soares da; Peixoto, Maria Manuela; Cruz, Ana Rita Pereira da; Gonçalves, Rui AbrunhosaThis study was conducted at Psychology Research Centre (UID/PSI/01662/2013), University of Minho, and supported by the Portuguese Foundation for Science and Technology and the Portuguese Ministry of Science, Technology and Higher Education through national funds and co-financed by FEDER through COMPETE2020 under the PT2020 Partnership Agreement (POCI-01-0145-FEDER-007653). The study was also supported by Grant SFRH/ BD/66110/2009 from the Portuguese Foundation for Science and Technology awarded to the first author.Item A Cluster Analysis on Sexual Boredom Profiles in A Community Sample of Men and Women(The Journal of Sex Researc, 2021-06-11) Oliveira, Leonor B. de; Rosa, Pedro Joel; Carvalho, Joana Patrícia Pereira de; Nobre, PedroResearch evidence of the attributes of sexual boredom is extremely limited. Understanding variability in the experience of sexual boredom may offer relevant insights for the field of human sexuality. This study aimed to explore the co-occurrence of sexual boredom and other sexuality-related dimensions. The sample consisted of 1021 participants aged between 18 and 75 years old (M = 32.68, SD = 8.79). A genderstratified cluster analysis was performed to classify individuals regarding their scores on sexual boredom, general boredom, sexual sensation seeking, sexual desire, sexual excitation, sexual pleasure, and sexual satisfaction. A three-cluster solution was revealed for both men and women. Based on our findings, we put forward a profile for the sexually bored individual, who is more likely to be married or cohabiting with a partner, to have a boredom prone personality, to lack sexual sensation seeking, experience low sexual pleasure and satisfaction, and to present with sexual arousal and/or desire problems. Women dealing with sexual boredom might present low sexual desire for their partner but experience high sex desire for attractive others. Results are critically discussed and implications for sexual therapy explored.Item Cognitive Stimulation of Elderly Individuals with Instrumental Virtual Reality-Based Activities of Daily Life(2019-01-01) Gamito, Pedro; Oliveira, Jorge; Morais, Diogo; Coelho, Cátia; Santos, Nuno; Alves, Catarina; Galamba, Ana; Soeiro, Miguel; Brito, RodrigoAs the demographic structure in western societies ages, the prevalence and impact of cognitive decline rises. Thus, new solutions to tackle this problem are required. The use of Information and Communication Tech- nologies (ICT)-based cognitive exercises has emerged in the last few decades, though with inconsistent results. Hence, we conducted a pre-post treatment study to further investigate this approach. We designed a set of virtual reality exercises that mimic activities of daily living by which the patient can train different cognitive domains. Twenty-five participants, ages 65–85, underwent 12 training sessions between the pre-treatment and post-treatment assessments. Significant increases were seen between the two assessments for some of the neuropsychological measures: visual memory, attention, and cognitive flexibility. Results also suggest that participants with lower baseline cognitive performance levels improved most after these sessions.Item Community sanctions: Offenders’ perceptions about their appropriateness(2021) Andrade, Joana Raquel Mendes; Cruz, Ana Rita Pereira da; Cunha, Olga Cecília Soares da; Gonçalves, Rui Abrunhosa; Rodrigues, Andreia de CastroItem Computerized cognitive training using virtual reality on everyday life activities for patients recovering from stroke(2020-04-07) Oliveira, Jorge; Gamito, Pedro; Lopes, Beatriz; Silva, Ana Rute Tavares; Galhordas, João; Pereira, Eduarda; Ramos, Elisabete; Silva, Ana Paula Lopes da; Jorge, Áurea; Fantasia, AntónioRecent studies argue that the use of virtual reality tasks depicting activities daily living may be an effective means for cognitive rehabilitation. The aim of this study was to test an ecologically oriented approach in virtual reality resembling the demands of everyday life activities for cognitive rehabilitation following stroke. The sample comprised 30 sub-acute stroke patients recovering from stroke in a rehabilitation hospital. They were assessed in a single-arm pre-post intervention study on global cognition, executive functions, memory and attention abilities. The intervention consisted of virtual reality in a multidomain cognitive training approach depicting everyday life tasks (preparing food, choosing clothes, shopping, etc.). Improvements were found in the assessed cognitive domains at 6 to 10 post-treatment sessions. In-depth analysis through reliable change scores has suggested larger treatment effects on global cognition. Overall results suggest that the use of virtual reality-based exercises on everyday life activities may be a useful cognitive rehabilitation approach to provide short-term gains in cognition following stroke.Item Connectedness and well-being in simulated nature(Wiley, 2021) Pasca, Laura; Carrus, Giuseppe; Loureiro, Ana Luisa Cardoso Marques Teixeira; Navarro, Oscar; Panno, Angelo; Tapía-Follen, Cesar; Aragonés, Juan IgnacioPeople relate to nature physically, cognitively and emotionally, and this relationship fosters their well-being. There are several types of environments that vary according to their degree of naturalness, raising the question of whether they each exert different effects on people, connectedness and well-being. In order to study the extent to which environmental connectedness and well-being are a function of viewing different types of nature, we conducted a study with 454 participants from five different countries, who viewed images on a computer screen of one of three types of environment (totally natural, quasi-natural or non-natural) and responded to a series of associated items. The results of a mediation analysis showed an indirect effect of type of environment on well-being through positive and negative affect and connectedness to nature. The corresponding ANOVAs revealed differences in the connectedness and well-being elicited by different types of environment, and in preference: totally natural and quasi-natural environments (with no differences between them) showed differences with non-natural environments. Therefore, our study results suggest the usefulness of images of natural environments in fostering people's well-being and connectedness to nature.Item Consolidación memoria implícita : efecto de la valencia emocional y tiempo de exposición mediante el uso de priming perceptual(Cuadernos Hispanoamericanos de Psicología, 2019) Polo, Javier; Castillo-Parra, Henry; Rosa, Pedro Joel; Oliveira, JorgeSe estudió el efecto de la valencia emocional y los tiempos de exposición en la consolidación de la memoria implícita mediante el uso del paradigma de priming perceptual enmascarado modificado, con reconocimiento de emociones bajo condiciones de consciencia limitada. Se presentaron rostros priming con expresiones emocionales de felicidad, rabia y neutro, en tiempos de exposición de 17ms, 33ms y 83 ms; posteriormente, los sujetos ejecutaron la tarea de memoria implícita, la cual consistía en recordar la emoción del rostro target de la primera tarea. Se encontraron diferencias estadísticamente significativas a nivel de la valencia emocional entre los diferentes tiempos de exposición en la tarea de procesamiento perceptual, en comparación con la tarea de consolidación de la memoria implícita a nivel de los tiempos de reacción. Igualmente, se encontraron diferencias estadísticamente significativas en los tiempos de exposición al comparar la tarea de procesamiento perceptual y la de consolidación de la memoria implícita. Los resultados obtenidos explican que existe una correlación entre las respuestas correctas de esta última tarea y las valencias emocionales, con cada uno de los tres tiempos de exposición. Estos resultados sugieren que las valencias emocionales influyen diferencialmente en las tareas de procesamiento perceptual y consolidación de la memoria implícita.Item COVID-19 and disenfranchised grief(Frontiers in Psychiatry, 2021) Albuquerque, Sara; Teixeira, Ana Margarida; Rocha, José CarlosItem Cultural differences in vocal emotion recognition: a behavioural and skin conductance study in Portugal and Guinea-Bissau(Psychological Research, 2021) Cosme, Gonçalo; Tavares, Vânia; Nobre, Guilherme; Lima, César; Sá, Rui Miguel Moutinho; Rosa, Pedro Joel; Prata, DianaCross-cultural studies of emotion recognition in nonverbal vocalizations not only support the universality hypothesis for its innate features, but also an in-group advantage for culture-dependent features. Nevertheless, in such studies, differences in socio-economic-educational status have not always been accounted for, with idiomatic translation of emotional concepts being a limitation, and the underlying psychophysiological mechanisms still un-researched. We set out to investigate whether native residents from Guinea-Bissau (West African culture) and Portugal (Western European culture)—matched for socio-economic-educational status, sex and language—varied in behavioural and autonomic system response during emotion recognition of nonverbal vocalizations from Portuguese individuals. Overall, Guinea–Bissauans (as out-group) responded significantly less accurately (corrected p < .05), slower, and showed a trend for higher concomitant skin conductance, compared to Portuguese (as in-group)—findings which may indicate a higher cognitive effort stemming from higher difficulty in discerning emotions from another culture. Specifically, accuracy differences were particularly found for pleasure, amusement, and anger, rather than for sadness, relief or fear. Nevertheless, both cultures recognized all emotions above-chance level. The perceived authenticity, measured for the first time in nonverbal cross-cultural research, in the same vocalizations, retrieved no difference between cultures in accuracy, but still a slower response from the out-group. Lastly, we provide—to our knowledge—a first account of how skin conductance response varies between nonverbally vocalized emotions, with significant differences (p < .05). In sum, we provide behavioural and psychophysiological data, demographically and language-matched, that supports cultural and emotion effects on vocal emotion recognition and perceived authenticity, as well as the universality hypothesis.Item Development and validation of the Portuguese version of the Eating Disorder Diagnostic Scale(Elsevier, 2018) Santos, Isabel Olímpia Figueiredo dos; Machado, Paulo Manuel Pinto Pereira Almeida; Esteves, Francisco GomesThis article presents the psychometric properties for the Portuguese population of a brief self-report scale for diagnosing anorexia nervosa (AN), bulimia nervosa (BN), and binge-eating disorder (BED): the Eating Disorder Diagnostic Scale (Stice et al., 2000). Method: To study the psychometric properties of EDDS, an exploratory factor analysis was done first, followed by a confirmatory factor analysis. Results: The results of the exploratory factor analysis revealed the existence of three components and the confirmatory factor analysis showed a structure with three latent variables (Body and Weight Concerns, Binge Eating Behaviour and Compensatory Behaviours), with a second order variable (Eating Disorder Symptoms) with a good adjustment fit. The internal consistency and the test–retest correlations revealed an adequate reliability and the inter-correlations of the EDDS subscales with other measures of the same and different constructs, supported the convergent and discriminant validity of this measure. Conclusions: Summing up, the EDDS seems to be a useful measure to assess eating disorders symptomatology in the Portuguese population.Item Diagnostic precision of the Wisconsin Card Sorting Test in assessing cognitive deficits in substance use disorders(2021-04-01) Faustino, Bruno; Oliveira, Jorge; Lopes, Paulo Jorge FerreiraThe Wisconsin Card Sorting Test (WCST) is a widely used neuropsychological instrument to assess executive functions related to cognitive flexibility and abstract reasoning. However, there is a lack of studies investigating the diagnostic precision of this instrument in sub- stance use disorders. In this study, we aimed at assessing the sensitivity and specificity of the WCST in discriminating the performance of participants with substance use disorder with cognitive deficits and participants from the general population without cognitive defi- cits. The sample comprised three groups of participants with substance use disorders (opi- oid use disorder in harm reduction with methadone maintenance; opioid use disorder in treatment in a therapeutic community; alcohol use disorder in a therapeutic community) and a normative group of healthy adults. The total sample consisted of 587 participants that were assessed with cognitive tests for executive functions, general cognitive function- ing, and self-reported depression. The results showed differences between groups in most WCST variables, providing evidence of discriminant validity for this test. Convergent validity was also established by weak to moderate correlations with general cognitive functioning. Cutoff points based on receiver operating characteristic (ROC) curves were calculated for the WCST variables. Overall, the WCST was sensitive to changes in cognitive flexibility and abstract reasoning that are key features of substance use disorders.Item Do parents of children with cancer want to participate in treatment decision-making?(ICMJE, 2020) Salvador, Ágata; Crespo, Carla Alexandra Mesquita; Roberto, Magda Sofia; Barros, LuísaPurpose: This study aimed to describe parents’ preferences regarding their role in treatment decision-making when a child has cancer and examines whether their preferences were related to the parents (sex and education level), patients’ characteristics (age group and treatment status), and healthcare context features (parents’ perception of family-centered care). Methods: Two-hundred and twenty-eight parents of children/adolescents with cancer were recruited from two Portuguese pediatric oncology wards. Participants provided sociodemographic and clinical information. The Control Preferences Scale for Pediatrics was used to assess the parents’ preferred role in treatment decision-making. The Measure of Process of Care assessed the parents’ perception of family-centered care (family-centered services and providing general information subscales). Results: Results showed that parents preferred a passive-collaborative role (44.8%), followed by collaborative (27.8%), passive (20.9%) and active-collaborative (6.5%). None preferred an active role. Chi-square test showed that most of the parents preferring an active-collaborative role had higher education degrees, while those preferring a passive role had lower education degrees. Additionally, groups did not differ according to the parents’ sex, patients’ age and treatment status. A multivariate analysis of variance showed that parents preferring an active-collaborative role reported lower scores on family-centered services compared to those preferring passive-collaborative and passive roles. Finally, no differences were found concerning providing general information scores. Conclusions: This study’s findings may guide professionals in identifying parents’ preferences regarding their participation in treatment decision-making process. Mapping their preferences may support professionals in promoting desirable levels of parental involvement when decisions are necessary in pediatric oncology context.Item Does caffeine matter for arousal? Affective and autonomic responses induced by caffeine in coffee intake: evidence from a double-blind tasting task(Journal of Applied Cognitive Neuroscience, 2021-03-26) Rodrigues, Fernando; Diogo, Julien; Rodrigues, Carla; Figueira, Cláudia; Rosa, Pedro JoelCoffee is consumed worldwide, but there are different types of espresso blends, each with its unique concentration of caffeine, which can have different effects on the human being. The aim of this study was to understand the effect of the impact of caffeine on the autonomic nervous system, evaluating the physiological changes and subjective responses due to different levels of caffeine intake. A double-blind tasting task consisting of one within-subject factor design (caffeine level: high / double caffeine mixture (blend A) vs single-charge caffeine mixture (blend B) vs low-caffeine mixture (blend c) allowed us to assess participants’ autonomic responses using Heart Rate Variability (HRV) and Pupillary Reactivity (PR). Arousal was also assessed through the Self-Assessment Manikin (SAM). Results revealed statistically significant differences in HRV and PR between coffee blends, showing the blend A,a more pronounced autonomic response that blend C. However, no significant differences were found in arousal level among coffee blends. These results are similar to previous research that pointed out to a discordance between subjective and objective measures when caffeine is consumed.Item Dropout among Perpetrators of Intimate Partner Violence Attending an Intervention Program(2022) Cunha, Olga Cecília Soares da; Silva, Andreia Fernandes da; Cruz, Ana Rita Pereira da; Rodrigues, Andreia de Castro; Braga, Teresa; Gonçalves, Rui AbrunhosaBatterer intervention programs (BIPs) are one of the most relevant strategies to reduce intimate partner violence (IPV). However, the rates of dropout are significantly high, which may impact the effectiveness of such strategies. Literature has identified several factors associated with BIP dropout; nonetheless findings remain inconsistent. The aims of this study were to analyze the differences between perpetrators who completed the program and those who droped out, in terms of sociodemographic, violence-related and intrapersonal variables, as well as identify the predictors of dropout. 83 IPV perpetrators completed a set of measures that assessed attitudes toward domestic violence, physical and psychological abuse of a partner, aggression, coping skills, and readiness to change. Variables related to past criminal history and sociodemographics were also colletected. 42.2% of IPV perpetrators failed to complete the intervention program. The results revealed that age and previous convictions by other crimes than IPV discriminated perpetrators who completed the program from those who droped out, such that, being young and having a previous conviction predicted dropout. These findings reveal a need to further analyze the impact of these factors so BIPs can be tailored to meet the specificities of IPV perpetrators and prevent treatment dropout.Item Effects of contact with nature on connectedness, environmental identity and evoked contents(Taylor & Francis, 2020) Mena-García, Antonio; Olivos-Jara, Pablo; Loureiro, Ana Luisa Cardoso Marques Teixeira; Navarro, OscarNatural experiences influence identity and the way of interacting with the environment, and their effects are varied, including wellbeing and positive thoughts towards nature. This study analyses the effects produced as a result of real or virtual experiences of nature. A total of 288 people took part in this research, distributed among three experimental conditions: nature walk, images of nature and control group. Changes were registered in terms of connectedness and environmental identity, caused by the experimental conditions and differences in the free evocations generated. Connection to nature was higher among those who took part in the nature walks, related to the evocation of positive emotions, memories of social experiences in nature and pro-environmental reflections. These results are interesting for the field of environmental education and the promotion of environmental values and behaviours.Item Energy-Saving Behavior: the Different Roles of Altruism and of Environmentalism(Editorial Pontifica Universidad Jeveriana, 2019) Loureiro, Ana Luisa Cardoso Marques Teixeira; Lima, Maria LuisaThis experimental study, in which 118 university students participated, addresses how environmental and altruistic cues induce energy-saving behavior and intention, and their interaction with environmental and altruistic values, thus testing the influence of context or situational variables in energy-saving behavior and intention. Additionally, it does an empirical approach to the role that environmental and altruistic values may have as individual predictors of energy-saving. Environmental and altruistic situational cues are operationalized by environment and altruism conceptual priming. The results reveal an interaction between situational variables and personal values: environment priming induced more energysaving behavior among individuals with lower altruistic values. The same effect is not observed for energy-saving intention. When the environment and altruism priming were present, individuals with lower altruistic values had less energy-saving intentions. These results underline the importance of distinguishing environmental and altruistic frames and motives when explaining energy-saving behavior.
