    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, 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.

    A Cluster Analysis on Sexual Boredom Profiles in A Community Sample of Men and Women
    (Edições Universitárias Lusófonas, 2021-06-11) Oliveira, Leonor B. de; Rosa, Pedro Joel; Carvalho, Joana Patrícia Pereira de; Nobre, Pedro; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    Research 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.

    Consolidación memoria implícita : efecto de la valencia emocional y tiempo de exposición mediante el uso de priming perceptual
    (Edições Universitárias Lusófonas, 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.

    Cultural differences in vocal emotion recognition: a behavioural and skin conductance study in Portugal and Guinea-Bissau
    (Edições Universitárias Lusófonas, 2021) Cosme, Gonçalo; Tavares, Vânia; Nobre, Guilherme; Lima, César; Sá, Rui Miguel Moutinho; Rosa, Pedro Joel; Prata, Diana; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    Cross-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.

    Desenvolvimento e Validação da Escala de Literacia Mediática e Informacional para Alunos dos 2º e 3º Ciclos do Ensino Básico em Portugal
    (Edições Universitárias Lusófonas, 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.

    Exploring hypersexuality pathways from eye movements : the role of (sexual) impulsivity
    (Edições Universitárias Lusófonas, 2021) Carvalho, Joana Patrícia Pereira de; Rosa, Pedro Joel; Štulhofer, Aleksandar; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    Background: Impulsivity is regarded as a key factor underpinning hypersexuality like-conditions. However, impulsivity is a multifaceted construct, and existing research has not been capturing such complexity, which includes the effects of domain-general and domain-specific impulsivity in hypersexuality. Aim: The aim of this study was to test the predictive role of specific impulsivity domains, ie, domain-general and domain-specific, in hypersexuality and its associated consequences. Methods: Fifty-five men and 58 women went through an emotional Go/-no-Go task (including sexual, high-valence positive, and neutral pictures), aimed at capturing domain-general and domain-specific impulsivity. Ocular metrics were further considered in order to increase the validity of the experimental task, and provide a metric of attention capturing. The study was carried out in a community sample. Outcomes: Self-reported (general)impulsivity and commission errors toward high-valence positive and sexual pictures (signaling domain-general and domain-specific impulsivity, respectively) were settled as independent variables, along with Time to First Fixation to stimuli, capturing early/uncontrolled attention. Scores on hypersexuality and negative consequences emerging from hypersexual behavior were settled as outcome variables. Results: Self-reported (general)impulsivity was the only predictor of hypersexuality scores, while negative consequences were best accounted by higher fixation time to sexual pictures. In all, findings did not support the role of domain-specific impulsivity (ie, sexual impulsivity) in hypersexuality. Clinical translation: Findings tentatively suggest that hypersexuality, as captured at the community level, may be best positioned within the general spectrum of psychopathology, thus influencing educational and clinical intervention protocols aimed at addressing hypersexuality related complaints. Protocols would be expected to primarily target general psychopathology phenomena, rather than specific sexual aspects. Strengths & limitations: This study implemented an innovative approach to capture different impulsivity domains, thus adding to previous literature in the field. However, the current study precludes the generalization of findings to clinical samples, where psychological comorbidities are expected to impact results. Further, findings must be read with caution given to limited effect sizes. Conclusion: While hypersexuality was related to self-reported (general) impulsivity, findings on the negative consequences associated with hypersexual behavior mirrored response patterns found in depression. Such evidence aligns with the assumption that hypersexuality related phenomena might be better positioned in the psychopathology domain, rather than simply framed as a specific sexual problem.

    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.

    Is Pupil Activity Associated With the Strength of Memory Signal for Words in a Continuous Recognition Memory Paradigm?
    (Edições Universitárias Lusófonas, 2021-11-23) Oliveira, Jorge; Fernandes, Marta; Rosa, Pedro Joel; Gamito, Pedro; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    Research on pupillometry provides an increasing evidence for associations between pupil activity and memory processing. The most consistent finding is related to an increase in pupil size for old items compared with novel items, suggesting that pupil activity is associated with the strength of memory signal. However, the time course of these changes is not completely known, specifically, when items are presented in a running recognition task maximizing interference by requiring the recognition of the most recent items from a sequence of old/new items. The sample comprised 42 healthy participants who performed a visual word recognition task under varying conditions of retention interval. Recognition responses were evaluated using behavioral variables for discrimination accuracy, reaction time, and confidence in recognition decisions. Pupil activity was recorded continuously during the entire experiment. The results suggest a decrease in recognition performance with increasing study-test retention interval. Pupil size decreased across retention intervals, while pupil old/new effects were found only for words recognized at the shortest retention interval. Pupillary responses consisted of a pronounced early pupil constriction at retrieval under longer study-test lags corresponding to weaker memory signals. However, the pupil size was also sensitive to the subjective feeling of familiarity as shown by pupil dilation to false alarms (new items judged as old). These results suggest that the pupil size is related not only to the strength of memory signal but also to subjective familiarity decisions in a continuous recognition memory paradigm.

    Ocular fixations modulate audiovisual semantic congruency when standing in an upright position
    (Edições Universitárias Lusófonas, 2021-06-02) Rodríguez-Martínez, Guillermo; Castillo-Parra, Henry; Rosa, Pedro Joel; Marroquin-Ciendúa, Fernando; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    Introduction: Multisensory audiovisual semantic congruency is the process by which visual information is perceived as integrated to auditory stimuli, because both coincide in terms of simultaneity and semantic correspondence. This study was aimed at establishing whether visual percepts, which semantically correspond to auditory stimuli, are associated with ocular fixations in modulating bottom-up areas while keeping a body posture alignment between the up-direction and the idiotropic axes, as well as in another orientation corresponding to a vectorial opposition between the up-direction and the head idiotropic axis. Method: Two groups (one for each position) were selected from a sample of 88 people. A bistable image was presented on a screen of a fixed 120 Hz eye-tracker device, providing background auditory stimuli so as to establish semantic congruencies and their relations to ocular fixations. Results: It was found that audiovisual semantic congruency is associated with fixations when idiotropic vectors are aligned with the up direction. Fixations manifested in bottom-up modulating areas are not associated with multisensory audiovisual semantic congruency when the head idiotropic vector is parallel with the gravity vector. Eye fixations decrease significantly if the head idiotropic axis is aligned with the gravity vector. Conclusion: It is concluded that body position can affect visual perceptual processes involved in the occurrence of semantic congruency.

    O papel mediador da autorrevelação sexual na relação entre a expressão de sentimentos e a satisfação sexual em adultos heterossexuais
    (Edições Universitárias Lusófonas, 2019) Pascoal, Patrícia; Lopes, Catarina Rasteiro; Rosa, Pedro Joel; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    O objetivo de deste estudo foi testar um modelo de mediação da expressão de sentimentos e a satisfação sexual via autorrevelação, enquanto processo, é uma variável mediadora significativa da associação entre a expressão de sentimentos e a satisfação sexual. A amostra deste estudo foi constituída por 564 participantes (370 mulheres, 65,60%), cisgénero, heterossexuais, numa relação diádica de exclusividade e compromisso. Foram testados dois modelos: um modelo de mediação simples e um modelo de mediação moderada, sendo este último usado para testa a influência do género no modelo de mediação. Os resultados demonstraram que, globalmente, homens e mulheres apresentaram valores médios idênticos na autorrevelação sexual e satisfação sexual; se contudo, na expressão de sentimentos, as mulheres apresentaram valores significativamente superiores. A expressão de sentimentos revelou-se uma variável preditora significativa da satisfação sexual e a autorrevelação sexual como uma variável parcialmente mediadora do modelo. No entanto, o género não modera a expressão de sentimentos e a autorrevelação. O presente estudo demonstra que a expressão de sentimentos e a autorrevelação sexual são importantes aspetos da satisfação sexual de ambos os géneros.

    Perceptual reversals and time-response analyses within the scope of decoding a bistable image
    (Edições Universitárias Lusófonas, 2022) Rodríguez-Martínez, Guillermo; Marroquín-Ciendúa, Fernando; Rosa, Pedro Joel; Castillo-Parra, Henry; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    A bistable image admits two possible interpretations, so that the observer can recognize the two percepts, but never at the same time. The alternations between percepts are called “perceptual reversals”. When the observer’s position is different from the upright position, the ability to make perceptual alternations may be impaired. Besides, the recognition of the percepts of a bistable image can be a complex reaction time visual task, if it involves recognizing two different conceptual units, added to the fact of having to make a subsequent report. A visual task was performed by 88 people in order to establish whether the perception of Boring’s bistable image My girlfriend or my mother-in-law is associated with areas that condition its interpretation. It was assumed that decoding the image and reporting the perceived percept implied a complex reaction time. The task itself was done in front of a fixed 120 Hz eye-tracker, in two opposite body positions. Analyses were made reviewing the association of the percepts with bottom-up modulation areas of the image, and considering ocular fixations made 200 and 250 milliseconds before the time of the report. The records of these fixations were obtained so as to establish which of the two reaction times (200 ms or 250 ms) was involved in the bottom-up modulation process from the moment of ocular fixation to the reports given by the participants. It was concluded that perceptual reversals decrease significantly when head idiotropic axis points in the gravity vector direction, in comparison to the upright position. Likewise, associations between visual percepts and bottom-up modulating areas of the image were found when analyses were done by considering ocular fixations made 250 ms before the moment of the report. Interpreting Boring’s bistable image implies a complex visual task in accordance with the results obtained.

    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.
    (Edições Universitárias Lusófonas, 2020) Pires, Carla Maria Batista Ferreira; Rosa, Pedro Joel; Vigário, Marina; Cavaco, Afonso Miguel das Neves; 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.
