Anterior Cruciate Ligament Reconstruction: Flowchart of Technical Options and R...
Guerra Pinto, Francisco; Alçada, Rita; Pacheco, Jácome; Moraes Sarmento, Gonçalo; Martinho, Carlos; Martins, António; Alçada, RitaThe anterior cruciate ligament (ACL) reconstruction is one of the most frequently performed orthopedic surgeries. Despite the extensive literature available, it is difficult to find a pragmatic description of the different technical variants that can guide multiple surgical decisions. In this review article, the technical variants of ACL reconstruction are systematically described, namely in the collection and ...
Designing a mood-mediated multi-level reasoner
Gomes, Samuel; Rocha, José Bernardo; Dias, João; Martinho, CarlosPsychology-oriented research extensively studied how affect influences human decision making. Particularly, the cognitive tuning assumption suggests that mood can serve to regulate between shallow and deliberative decisions - a more negative mood means higher deliberation. This work proposes a model that mimics the cognitive tuning assumption. To that end, the Collective Risk Dilemma (CRD) game For the Planet w...
Heroine’s learning journey: motivating women in stem online courses through the...
Costa, Luis Felipe Coimbra; Gomes, Samuel; Santos, Ana Moura; Xexéo, Geraldo Bonorino; De Lima, Yuri Oliveira; Prada, Rui; Martinho, Carlos; Dias, JoãoAlthough Science, Technology, Engineering, and Mathematics (STEM) are essential for the development of society, men hugely outnumber women in the majority of STEM fields in higher education, a factor that hinders inclusion and restricts the possibility of having different points-of-view. Previous studies indicate multiple causes of low female motivation in STEM degrees and careers, which inspired several initia...
Modeling students’ behavioral engagement through different in-class behavior st...
Gomes, Samuel; Costa, Luis; Martinho, Carlos; Dias, João; Xexéo, Geraldo; Moura Santos, AnaBackground The growing necessity of providing better education, notably through the development of Adaptive Learning Systems (ALSs), leveraged the study of several psychological constructs to accurately characterize learners. A concept extensively studied in education is engagement, a multidimensional construct encompassing behavioral expression and motivational backgrounds. This metric can be used to not only ...
Serious game-based psychosocial intervention to foster prosociality in cyberbul...
Ferreira, Paula; Veiga Simão, Ana; Paiva, Ana; Martinho, Carlos; Prada, Rui; Rocha, JoséBystanders of cyberbullying play an important role in the resolution of such situations and therefore, it is beneficial to promote self-regulation strategies that enable them to engage in prosocial behavior in these contexts. We propose that serious game-based psychosocial interventions with profile-based social agents can encourage prosocial bystander behavior in cyberbullying. A pilot quasi-experimental study...
Reward-mediated individual and altruistic behavior
Gomes, Samuel; Alves, Tomás; Dias, João; Martinho, CarlosRecent research has taken a particular interest in observing the dynamics between individual and altruistic behavior. This is a commonly approached problem when reasoning about social dilemmas, which have a plethora of real-world counterparts in the fields of education, health, and economics. Weighing how incentives influence in-game behavior, our study examines individual and altruistic interactions in the con...
Exploring empathy in cyberbullying with serious games
Ferreira, Paula; Veiga Simão, Ana; Paiva, Ana; Martinho, Carlos; Prada, Rui; Ferreira, Aristides I.; Santos, FranciscoThis study examined whether experiencing a multiplayer serious game could foster cognitive empathy in adolescent bystanders of cyberbullying, empathic concern for these situations and affective empathy towards those involved during game play. We also explored the players’ selfreflections about cyberbullying scenarios in the game. A quasi-experimental design was used. While participants in an alternative interve...
The influence of reward on the social valence of interactions
Alves, Tomas; Gomes, Samuel; Dias, João; Martinho, CarlosThroughout the years, social norms have been promoted as an informal enforcement mechanism for achieving beneficial collective outcomes. Among the most used methods to foster interactions, framing the context of a situation or setting in-game rules have shown strong results as mediators on how an individual interacts with their peers. Nevertheless, we found that there is a lack of research regarding the use of ...

Marcos, Adérito; Carvalho, Elizabeth; Martinho, Carlos; Cláudio, Ana Paula; Carmo, Maria Beatriz; Rocio, VitorEste artigo apresenta reflexões seminais acerca da utilização de tutores virtuais no sistema de e-learning da Universidade Aberta. O tutor virtual é uma analogia do tutor humano, adota uma interface antropomórfica com características emocionais, comumente denominado de avatar, que integra inteligência artificial e pode constituir uma abordagem interessante, tanto para o professor como para os estudantes, se se ...
Virtual tutoring
Marcos, Adérito; Cláudio, Ana Paula; Martinho, Carlos; Barros, Daniela Melaré Vieira; Carvalho, Elizabeth; Carmo, Maria Beatriz; Seixas, SóniaThe project VIRTUAL TUTORING – the virtual tutor as learning mediating artifact in online university education, is an ongoing project, with the main goal of analyzing the pedagogic impact of an anthropomorphic user interface on a typical distance learning environment targeted to support online higher education. This demands the creation of animated avatars for virtual tutors, able to display intelligent behavio...
