    Adaptive Non-Immersive VR Environment for Eliciting Fear of Cockroaches : a Physiology-Driven Approach Combined with 3D-TV Exposure
    (Universidad de San Buenaventura, 2020) Rosa, Pedro Joel; Luz, FIlipe Costa; Junior, Roberto; Oliveira, Jorge; Morais, Diogo; Gamito, Pedro; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    Non-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.

    Attentional orienting to biologically fear-relevant stimuli: data from eye tracking using the continual alternation flicker paradigm
    (Edições Universitárias Lusófonas, 2011) Rosa, Pedro Joel; Gamito, Pedro; Oliveira, Jorge; Morais, Diogo; Saraiva, Tomaz; Escola de Psicologia e Ciências da Vida
    Snakes are thought as fear-relevant stimuli (biologically prepared to be associated with fear) which can lead to an enhanced attentional capture when compared fear-irrelevant stimuli. Inherent limitations related to the key-press behaviour might be bypassed with the measurement of eye movements, since they are more closely related to attentional processes than reaction times. An eye tracking technique was combined with the flicker paradigm in two studies. A sample of university students was gathered. In both studies, an instruction to detect changes between the pair of scenes was given. Attentional orienting for the changing element in the scene was analyzed, as well the role of fear of snakes as a moderator variable. The results for both studies revealed a significant shorter time to first fixation for snake stimuli when compared to control stimuli. A facilitating effect of fear of snakes was also found for snakes, presenting the highly fear participants a shorter a time to first fixation for snake stimuli when compared to low-feared participants. The results are in line with current research that supports the advantage of snakes to grab attention due their evo-biological significance.

    Consolidación memoria implícita : efecto de la valencia emocional y tiempo de exposición mediante el uso de priming perceptual
    (2019) Polo, Javier; Castillo-Parra, Henry; Rosa, Pedro Joel; Oliveira, Jorge; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    Se 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.

    Desenvolvimento e Validação da Escala de Literacia Mediática e Informacional para Alunos dos 2º e 3º Ciclos do Ensino Básico em Portugal
    (University of Lusophone Humanities and Technology, 2018) Costa, Conceição; Tyner, Kathleen; Rosa, Pedro Joel; Sousa, Carla Patrícia Gonçalves e; Henriques, Sara; Faculdade de Ciências Sociais, Educação e Administração
    A comunicação e a partilha de significados num mundo altamente mediatizado requer múltiplas literacias. Independentemente das definições e abordagens, estas literacias têm vindo a abrir debates críticos sobre quais as competências que os cidadãos devem ter e desde quando elas devem ser adquiridas. No presente estudo damos conta do processo de desenvolvimento e validação de uma Escala de Literacia Mediática e Informacional (ELMI) para alunos dos 2º e 3º ciclos do Ensino Básico em Portugal. A validade de construto foi examinada via Análise Fatorial Exploratória (AFE) para uma amostra de 1151 participantes. A AFE revelou uma estrutura trifatorial constituída por 22 itens que explicam 53.23% da variância total. A escala apresenta uma consistência interna global excelente (ωt = .92), com adequada consistência interna para todas as subescalas (α de Cronbach e α Ordinal > .70). Os resultados evidenciam boas qualidades psicométricas da ELMI que poderá ser um instrumento vantajoso para o prognóstico e avaliação de intervenções relacionadas com a literacia mediática.

    Does caffeine matter for arousal? Affective and autonomic responses induced by caffeine in coffee intake: evidence from a double-blind tasting task
    (Edições Universitárias Lusófonas, 2021-03-26) Rodrigues, Fernando; Diogo, Julien; Rodrigues, Carla; Figueira, Cláudia; Rosa, Pedro Joel; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    Coffee 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.

    Grabbing attention while reading website pages: the influence of verbal emotional cues in advertising
    (Edições Universitárias Lusófonas, 2011) Ferreira, Paulo Jorge Quaresma; Rita, Paulo; Morais, Diogo; Rosa, Pedro Joel; Oliveira, Jorge; Gamito, Pedro; Santos, Nuno; Soares, Fábio; Sottomayor, Catarina; Escola de Psicologia e Ciências da Vida
    The increasing use of the World Wide Web has promised a huge advertising platform for marketers. Investment in online advertising is growing and is expected to overcome traditional media. However, recent studies have reported that users avoid looking at advertising displayed on the World Wide Web. This study aimed at examining the impact of verbal emotional cues (negative/neutral/positive) to capture attention on website’s advertising areas through an eye tracker system. The results revealed significant statistical differences between fixations to negative, positive words and neutral words. Significant differences between the number of fixations and recognition of the target words were found only for the negative valence words. We conclude that negative emotional words could play a major role on user attention to advertising.

    Hemispheric asymmetries in recognition memory for negative and neutral words
    (Edições Universitárias Lusófonas, 2011) Oliveira, Jorge; Gamito, Pedro; Perea, Maria; Ladera, Valentina; Morais, Diogo; Rosa, Pedro Joel; Saraiva, Tomaz; Escola de Psicologia e Ciências da Vida
    Federmeier and Benjamin (2005) have suggested that semantic encoding for verbal information in the right hemisphere can be more effective when memory demands are higher. However, other studies (Kanske & Kotz, 2007) also suggest that visual word recognition differ in function of emotional valence. In this context, the present study was designed to evaluate the effects of retention level upon recognition memory processes for negative and neutral words. Sample consisted of 15 right-handed undergraduate portuguese students with normal or corrected to normal vision. Portuguese concrete negative and neutral words were selected in accordance to known linguistic capabilities of the right hemisphere. The participants were submitted to a visual half-field word presentation using a continuous recognition memory paradigm. Eye movements were continuously monitored with a Tobii T60 eye-tracker that showed no significant differences in fixations to negative and neutral words. Reaction times in word recognition suggest an overall advantage of negative words in comparison to the neutral words. Further analysis showed faster responses for negative words than for neutral words when were recognised at longer retention intervals for left-hemisphere encoding. Electrophysiological data through event related potentials revealed larger P2 amplitude over centro-posterior electrode sites for words studied in the left hemifield suggesting a priming effect for right-hemisphere encoding. Overall data suggest different hemispheric memory strategies for the semantic encoding of negative and neutral words.

    Sexual health and the pandemic crisis : testing the role of psychological vulnerability/protective factors on sexual functioning and sexual distress during a critical life period
    (Edições Universitárias Lusófonas, 2022-01) Nobre, Pedro; Rosa, Pedro Joel; Vasconcelos, Priscila; Tavares, Inês; Carvalho, Joana Patrícia Pereira de; Gomes, Ana Luísa de Matos Dias Quinta; Moura, Catarina; Carrito, Manuela; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    Recent findings suggest that the current COVID-19 pandemic has a potential negative impact in several areas of life, including sexual health. However, less is known about the psychological dimensions that may work as vulnerability/protective factors for the development of sexual problems in the current pandemic. The current study used a longitudinal design to examine the role played by personality trait factors (neuroticism, extraversion) as well as psychosexual factors (sexual beliefs) in predicting sexual functioning and sexual distress across time during the current pandemic crisis. A total of 528 individuals (337 women) completed a web survey assessing sexual health indicators and psychological factors. The first wave was conducted during the confinement period in Portugal (N = 528) between May and June 2020 and the second four months later (N = 146), when strict confinement rules were over. Generalized estimating equations (GEE) were used to examine the ability of psychological factors to predict sexual functioning and distress across time, while controlling for age and gender. Results indicated that sexual distress at time point 2 was lower than during confinement, and men had lower levels of sexual functioning post-confinement while no significant difference was observed for women. Moreover, higher levels of neuroticism and age-related beliefs significantly predicted lower sexual functioning as well as higher sexual distress, whereas lower levels of extraversion predicted lower sexual functioning after controlling for age and gender effects. Findings support the role of psychological vulnerability factors to predict sexual problems across time and may have important implications in the prevention and treatment of sexual dysfunctions.

    Validation of a new tool for evaluating subjects’ satisfaction with medicine package leaflets : a cross-sectional descriptive study
    (Associacao Paulista de Medicina, 2019-09-01) Pires, Carla; Rosa, Pedro Joel; Vigário, Marina; Cavaco, Afonso; CBIOS (FCT) - Centro de Investigação em Biociências e Tecnologias da Saúde; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    BACKGROUND: Package leaflets of medicines need to be intelligible, but tools for their evaluation are scarce. OBJECTIVE: To validate a new tool for assessing subjects’ satisfaction with medicine package leaflets (LiS-RPL). DESIGN AND SETTING: Cross-sectional descriptive study conducted in two regions of Portugal (Lisbon and Centre). METHODS: 503 participants (53.1% male) were selected according to convenience and homogenously distributed into three groups: 1 to 6; 7 to 12; and > 12 years of schooling. LiS-RPL was developed based on international regulation guidelines and was initially composed of 14 items. Twelve package leaflets were tested. Dimensionality calculations included: exploratory factor analysis and minimum rank factor analysis; Kaiser-Meyer-Olkin index and Bartlett’s sphericity test to assess matrix adequacy for exploratory factor analysis; exploratory bifactor analysis with Schmid-Leiman solution to detect possible existence of a broad second-order factor; and Bentler’s Simplicity Index and Loading Simplicity Index to assess factor simplicity. Diverse coefficients were calculated to assess reliability. RESULTS: Minimum rank factor analysis detected a two-factor or single-factor structure. Exploratory factor analysis with 12 items showed a two-factor structure, explaining 69.11% of the variance. These items were strongly correlated with each other (r = 0.80). Schmid-Leiman: all items seemed to represent the general factor (loadings above 0.50), which was 76.4% of the extracted variance. Simplicity indices were good (percentile 99): Bentler’s Simplicity Index of 0.99 and Loading Simplicity Index of 0.48. Internal consistency indexes indicated good reliability. LiS-RPL was shown to be homogenous. CONCLUSION: LiS-RPL is a validated tool for evaluating subjects’ satisfaction with medicine package leaflets.
