A capacidade de noticing do pensamento algébrico dos alunos: um estudo na forma...
Cabral, Joana; Mendes, Fátima; Oliveira, HéliaA capacidade de noticing é fundamental para as práticas do professor, pelo que é importante que a formação (inicial e contínua) promova oportunidades para que os formandos a desenvolvam. Em particular, é essencial que os (futuros) professores desenvolvam a capacidade de noticing do pensamento dos alunos, em domínios matemáticos específicos, como o pensamento algébrico. O presente artigo tem como objetivo compr...
The Psychometric Properties of a Portuguese Version of the Trait-Meta Mood Scal...
Cabral, Joana; Brandão, Tânia; Lamela, DiogoThis study examined the psychometric properties of the Portuguese version of Trait Meta-Mood Scale (TMMS). The TMMS is a self-report measure that assesses stable individual differences in the way people attend, discriminate, and repair their mood and emotions. Exploratory and confirmatory factor analyses (CFA) were conducted in a sample of 1070 Portuguese university students, aged 17–30 years. Attachment, copin...
Personal stigma, determinants of intention to use technology, and acceptance of...
Lamela, Diogo; Cabral, Joana; Coelho, Sara; Jongenelen, Inês MartinsDespite showing comparable levels of efficacy, internet-based psychological interventions (IPI) exhibited lower acceptance and intention of use as compared to psychological treatment delivered by face-to-face methods. Surprisingly, no research has inspected whether IPI acceptance is associated with variables linked with intentions of technology use and with barriers to seeking professional psychological help, s...
Awakening: Predicting external stimulation to force transitions between differe...
Deco, Gustavo; Cruzat, Josephine; Cabral, Joana; Tagliazucchi, Enzo; Laufs, Helmut; Logothetis, Nikos K.; Kringelbach, Morten L.A fundamental problem in systems neuroscience is how to force a transition from one brain state to another by external driven stimulation in, for example, wakefulness, sleep, coma, or neuropsychiatric diseases. This requires a quantitative and robust definition of a brain state, which has so far proven elusive. Here, we provide such a definition, which, together with whole-brain modeling, permits the systematic...
Disrupted brain structural connectivity in Pediatric Bipolar Disorder with psyc...
Fernandes, Henrique M.; Cabral, Joana; Hartevelt, Tim J. van; Lord, Louis-David; Gleesborg, Carsten; Møller, Arne; Deco, Gustavo; Whybrow, Peter C.Bipolar disorder (BD) has been linked to disrupted structural and functional connectivity between prefrontal networks and limbic brain regions. Studies of patients with pediatric bipolar disorder (PBD) can help elucidate the developmental origins of altered structural connectivity underlying BD and provide novel insights into the aetiology of BD. Here we compare the network properties of whole-brain structural ...
Altered ability to access a clinically relevant control network in patients rem...
Figueroa, Caroline A.; Cabral, Joana; Mocking, Roel J. T.; Rapuano, Kristina M.; van Hartevelt, Tim J.; Deco, Gustavo; Expert, Paul; Schene, Aart H.Neurobiological models to explain vulnerability of major depressive disorder (MDD) are scarce and previous functional magnetic resonance imaging studies mostly examined "static" functional connectivity (FC). Knowing that FC constantly evolves over time, it becomes important to assess how FC dynamically differs in remitted-MDD patients vulnerable for new depressive episodes. Using a recently developed method to ...
A Kuramoto model of self-other integration across interpersonal synchronization...
Heggli, Ole Adrian; Cabral, Joana; Konvalinka, Ivana; Vuust, Peter; Kringelbach, Morten L.Human social behaviour is complex, and the biological and neural mechanisms underpinning it remain debated. A particularly interesting social phenomenon is our ability and tendency to fall into synchronization with other humans. Our ability to coordinate actions and goals relies on the ability to distinguish between and integrate self and other, which when impaired can lead to devastating consequences. Interper...
Discovery of key whole-brain transitions and dynamics during human wakefulness ...
Stevner, A. B. A.; Vidaurre, D.; Cabral, Joana; Rapuano, K.; Nielsen, S. F. V.; Tagliazucchi, E.; Laufs, H.; Vuust, P.; Deco, G.; Woolrich, M. W.The modern understanding of sleep is based on the classification of sleep into stages defined by their electroencephalography (EEG) signatures, but the underlying brain dynamics remain unclear. Here we aimed to move significantly beyond the current state-of-the-art description of sleep, and in particular to characterise the spatiotemporal complexity of whole-brain networks and state transitions during sleep. In...
Dynamical exploration of the repertoire of brain networks at rest is modulated ...
Lord, Louis-David; Expert, Paul; Atasoy, Selen; Roseman, Leor; Rapuano, Kristina; Lambiotte, Renaud; Nutt, David J.; Deco, GustavoGrowing evidence from the dynamical analysis of functional neuroimaging data suggests that brain function can be understood as the exploration of a repertoire of metastable connectivity patterns ('functional brain networks'), which potentially underlie different mental processes. The present study characterizes how the brain's dynamical exploration of resting-state networks is rapidly modulated by intravenous i...
Forms of Self-Criticizing and Self-Reassuring Scale: Adaptation and Validation ...
Carvalho, Célia Barreto; Benevides, Joana; da Motta, Carolina; Cabral, Joana; Pereira, Carolina; Teixeira, Marco; Peixoto, ErmelindoSelf-criticism may be understood as a harmful self-evaluation that implies feelings of uselessness and guilt towards perceptions of failure. Goals: to explore the latent structure and other psychometric properties of the Forms of Self-Criticizing and Reassuring Scale for Children (FSCRS -C) of the Portuguese population. Method: the FSCRS-C was administered to 249 Azorean children. Results: a two-dimensional mod...
