Cardiac interoceptive processing across psychopathy dimensions: evidence from t...
Campos, Carlos; Sá, Catarina; Mazer, Prune; Pasion, Rita; Garcez, Helena; Paiva, Tiago O.; Braga, Patrícia Vilela; Rocha, Nuno BarbosaPsychopathy is a multidimensional personality structure encompassing interpersonal, affective, and behavioral traits. Interoception (ability to perceive and subjectively experience inner bodily states) may be a putative mechanism underlying the etiological pathways of psychopathy. Individual differences in interoceptive processing across psychopathy dimensions may interfere with the ability to perceive somatic ...
Uncertainty deconstructed: conceptual analysis and state-of-the-art review of t...
Botelho, Catarina; Fernandes, Carina; Campos, Carlos; Pasion, Rita; Garcez, Helena; Ferreira-Santos, Fernando; Barbosa, Fernando; Maques-Teixeira, JoãoRisk and uncertainty are central concepts of decision neuroscience. However, a comprehensive review of the literature shows that most studies define risk and uncertainty in an unclear fashion or use both terms interchangeably, which hinders the integration of the existing findings. We suggest uncertainty as an umbrella term that comprises scenarios characterized by outcome variance where relevant information ab...
The Intolerance of Uncertainty Scale (IUS): Translation and adaptation to Europ...
Botelho, Catarina; Barbosa, Fernando; Campos, Carlos; Fernandes, Carina; Ferreira-Santos, Fernando; Marques-Teixeira, João; Pasion, RitaIntolerance of uncertainty is defined as the individual’s excessive propensity to find unacceptable the probability of a negative event occurring (Dugas et al., 2001b; Buhr & Dugas, 2002). This propensity is brought up bya set of negative beliefs about uncertainty and its consequences (e.g., uncertainty is unacceptable and should be avoided, and/or it leads to the inability to act;Buhr & Dugas, 2002; Freeston e...
Abnormal habituation of the auditory event-related potential P2 component in pa...
Mazer, Prune; Macedo, Inês; Paiva, Tiago O.; Ferreira-Santos, Fernando; Paison, Rita; Barbosa, Fernando; Almeida, Pedro; Silveira, CelesteAuditory event-related potentials (ERP) may serve as diagnostic tools for schizophrenia and inform on the susceptibility for this condition.Particularly, the examination of N1 and P2 components of the auditory ERP may shed light on the impairments of information processing streams in schizophrenia. However, the habituation properties (i.e., decreasing amplitude with the repeated presentation of an auditory stim...
Psychopathy, criminal intentions, and abnormal appraisal of the expected outcom...
Próspero-Luis, João; Moreira, Pedro Miguel Silva; Paiva, Tiago O.; Teixeira, Cátia P.; Costa, Patrício Soares; Almeida, Pedro R.Purpose Impaired emotional learning is one of the hallmark features of psychopathy. The abnormal processing of cues of reward and punishment, and its impact in decision‐making, has mostly been supported by laboratorial studies. In this report, we have analysed the effect of psychopathy in the formation of attitudes towards committing theft, and its impact in the intention to reoffend after release. Methods A se...
Empathic, moral and antisocial outcomes associated with distinct components of ...
Almeida, Pedro R.; Seixas, Maria João; Ferreira-Santos, Fernando; Vieira, Joana B.; Paiva, Tiago O.; Moreira, Pedro S.; Costa, Patrício SoaresIn the present report we analyzed the associations between the facets of the recent Triarchic Measure of Psychopathy (TriPM) and distinct dimensions of empathy, morality, and antisocial behavior. Three hundred and seventy-four participants from the community completed the TriPM, the Interpersonal Reactivity Index and the Moral Foundations Questionnaire. A subset of one hundred and three participants completed a...
