- Empathy by default: correlates in the brain at restPublication . Silva, Patrícia Oliveira; Maia, Liliana; Coutinho, Joana; Frank, Brandon; Soares, José Miguel; Sampaio, Adriana; Gonçalves, ÓscarBackground: Empathy, defi ned as the ability to access and respond to the inner world of another person, is a multidimensional construct involving cognitive, emotional and self-regulatory mechanisms. Neuroimaging studies report that empathy recruits brain regions which are part of the social cognition network. Among the different resting state networks, the Default Mode Network (DMN) may be of particular interest for the study of empathy since it has been implicated in social cognition tasks. Method: The current study compared the cognitive and emotional empathy scores, as measured by the Interpersonal Reactivity Index, with the patterns of activation within the DMN, through the neuroimaging methodology of resting-state functional magnetic resonance. Results: Results suggest a signifi cant positive correlation between cognitive empathy and activation of the bilateral superior medial frontal cortex nodes of the DMN. Contrastingly, a negative correlation was found between emotional empathy and the same brain region. Conclusions: Overall, this data highlights a critical role of the medial cortical regions of the DMN, specifi cally its anterior node, for both cognitive and emotional domains of the empathic process.
- Evidências de validade da versão portuguesa do ìndice de Reatividade Interpessoal para CasaisPublication . Coutinho, Joana; Beiramar, Ana; Silva, Carla; Lema, Alberto; Lima, Vânia; GraceIII, Randolph; Oliveira-Silva, Patrícia; Gonçalves, Óscar; Sampaio, AdrianaEste estudo teve como principal objetivo traduzir e adaptar para língua portuguesa o Índice de Reatividade Interpessoal para Casais (IRIC), analisando as propriedades psicométricas da versão portuguesa. Esse é um instrumento de avaliação da empatia em casais, que resultou da adaptação de uma das mais usadas escalas de empatia, o Índice de Reatividade Interpessoal de Davis, para o contexto das relações íntimas. O IRIC avalia dimensões de empatia cognitiva (tomada de perspetiva) e emocional (preocupação empática), importantes para a estabilidade e satisfação das relações conjugais. A escala original foi traduzida para português e administrada a 148 sujeitos que estavam numa relação amorosa há pelo menos um ano. A maioria dos sujeitos eram mulheres com uma média de idades de 27 anos. Os resultados revelam uma estrutura fatorial semelhante à escala original, valores adequados de consistência interna (alfa de Cronbach=0,82) e bons níveis de validade externa com uma escala de ajustamento diádico.
- Interplay between the salience and the default mode network in a social-cognitive task toward a close otherPublication . Costa, Cátia Ribeiro da; Soares, Jose M.; Oliveira-Silva, Patrícia; Sampaio, Adriana; Coutinho, Joana F.Social cognition relies on two main subsystems to construct the understanding of others, which are sustained by different social brain networks. One of these social networks is the default mode network (DMN) associated with the socio-cognitive subsystem (i.e., mentalizing), and the other is the salience network (SN) associated with the socio-affective route (i.e., empathy). The DMN and the SN are well-known resting state networks that seem to constitute a baseline for the performance of social tasks. We aimed to investigate both networks' functional connectivity (FC) pattern in the transition from resting state to social task performance. A sample of 38 participants involved in a monogamous romantic relationship completed a questionnaire of dyadic empathy and underwent an fMRI protocol that included a resting state acquisition followed by a task in which subjects watched emotional videos of their romantic partner and elaborated on their partner's (Other condition) or on their own experience (Self condition). Independent component and ROI-to-ROI correlation analysis were used to assess alterations in task-independent (Rest condition) and task-dependent (Self and Other conditions) FC. We found that the spatial FC maps of the DMN and SN evidenced the traditional regions associated with these networks in the three conditions. Anterior and posterior DMN regions exhibited increased FC during the social task performance compared to resting state. The Other condition revealed a more limited SN's connectivity in comparison to the Self and Rest conditions. The results revealed an interplay between the main nodes of the DMN and the core regions of the SN, particularly evident in the Self and Other conditions.
- Nodes of the default mode network implicated in the quality of empathic responses: a clinical perspective of the empathic responsePublication . Oliveira-Silva, Patrícia; Maia, Liliana; Coutinho, Joana; Moreno, Ana Filipa; Penalba, Lucia; Frank, Brandon; Soares, José Miguel; Sampaio, Adriana; Gonçalves, Óscar F.The ability to empathize with another person's inner experience is believed to be a central element of our social interactions. Previous research has focused on cognitive (e.g., theory of mind) and emotional (e.g., emotional contagion) empathy, and less on behavioral factors (i.e., the ability to respond empathically). Recent studies suggest that the Default Mode Network (DMN) mediates individual variability in distinct empathy-related behaviors. However, little is known about DMN activity during actual empathic responses, understood in this study as the ability to communicate our understanding of the others’ experience back to them. This study used an empathy response paradigm with 28 participants (22-37 years old) to analyze the relationship between the quality of empathic responses to 14 empathy-eliciting vignettes and patterns of attenuation in the DMN. Overall, the results suggest that high levels of empathic response, are associated with sustained activation of the DMN when compared with lower levels of empathy. Our results demonstrate that the DMN becomes increasingly involved in empathy-related behavior, as our level of commitment to the other's experience increases. This study represents a first attempt to understand the relation between the capacity for responding in a supportive way to others’ needs and the intra-individual variability of the pattern of the DMN attenuation. Here we underline the critical role that the DMN plays in high-level social cognitive processes and corroborate the DMN role in different psychiatric disorders associated with a lack of empathy.
- Reviewing working memory training gains in healthy older adults: a meta-analytic review of transfer for cognitive outcomesPublication . Teixeira-Santos, Ana C.; Moreira, Célia S.; Magalhães, Rosana; Magalhães, Carina; Pereira, Diana R.; Leite, Jorge; Carvalho, Sandra; Sampaio, AdrianaThe objective of this meta-analytic review was to systematically assess the effects of working memory training on healthy older adults. We identified 552 entries, of which 27 experiments met our inclusion criteria. The final database included 1130 participants. Near- and far-transfer effects were analysed with measures of short-term memory, working memory, and reasoning. Small significant and long-lasting transfer gains were observed in working memory tasks. Effects on reasoning was very small and only marginally significant. The effects of working memory training on both near and far transfer in older adults were moderated by the type of training tasks; the adopted outcome measures; the training duration; and the total number of training hours. In this review, we provide an updated review of the literature in the field by carrying out a robust multi-level metaanalysis focused exclusively on working memory training in healthy older adults. Recommendations for future research are suggested.
- Vagal modulation of 1-month-old infants to auditory stimuli is associated with self-regulatory behaviorPublication . Cruz, Sara; Ferreira-Santos, Fernando; Oliveira-Silva, Patrícia; Ribeiro, Eugénia; Gonçalves, Óscar; Sampaio, AdrianaDuring infancy, cardiac vagal modulation has been associated with attentional and social engagement behaviors. While studies have shown that infants display a behavioral repertoire that enables them to interact with others by being able to regulate themselves in order to attend to and to discriminate emotional and social cues, vagal modulation to sensory stimuli and its association with behavioral outcomes at early ages remains to be addressed. In this study, we analyzed the cardiac vagal response of 1-month-old infants to two auditory stimuli intensities and whether vagal response was associated with social interactive and self-regulatory abilities. Therefore, we recorded cardiac and respiratory physiological responses in 28 infants using a Biopac System. Neurobehavioral assessment was performed using the Neonatal Behavioral Assessment Scale. We observed increased respiratory sinus arrhythmia (RSA) amplitude to both auditory stimuli intensities when compared to baseline. No intensity effect was found for the RSA response. Additionally, we observed that higher RSA amplitude to both auditory stimuli was positively correlated with adjusted self-regulatory behaviors, suggesting a convergence between multiple measures assessing infants' state regulation. Results are discussed in light of 1-month-old infants' auditory stimuli processing and its implications for regulatory behaviors and the emergent social-like behaviors.
