Publicação Acesso Aberto Music and states of consciousness: A narrative review of the broader significance of music to understanding absorption, mind wandering and creative thought2024-10-11 - Palhares, Pedro T.; Sas, Madalina I.; Gonçalves, Óscar F.Due to music's extraordinary capacity to temporarily alter mental and physical states, the domain of musical experience offers a natural and accessible field of investigation for the study of states of consciousness. However, despite the continued emergence of music-related investigations into conscious experience, their research paradigms remain on the fringes of consciousness research, with the broader significance of their contributions often overlooked. In this narrative review, we aimed to address this gap by offering a twofold contribution. Firstly, we have highlighted and critically assessed key contributions of empirical research in music psychology and music neuroscience to our understanding of non-ordinary states of consciousness, such as absorption, mind wandering and creative thought, emphasizing the broader significance of exploring consciousness through music. Secondly, we have identified the unique aspects of music that offer special insight into consciousness and discussed how these aspects can shape future investigations. Overall, our review underscores the importance of integrating music into consciousness research and highlights avenues for future exploration in this interdisciplinary field.Publicação Acesso Aberto Visual perceptual learning of form–motion integration: Exploring the involved mechanisms with transfer effects and the equivalent noise approach2024-09-26 - Donato, Rita; Contillo, Adriano; Campana, Gianluca; Roccato, Marco; Gonçalves, Óscar F.; Pavan, AndreaBackground: Visual perceptual learning plays a crucial role in shaping our understanding of how the human brain integrates visual cues to construct coherent perceptual experiences. The visual system is continually challenged to integrate a multitude of visual cues, including form and motion, to create a unified representation of the surrounding visual scene. This process involves both the processing of local signals and their integration into a coherent global percept. Over the past several decades, researchers have explored the mechanisms underlying this integration, focusing on concepts such as internal noise and sampling efficiency, which pertain to local and global processing, respectively. Objectives and Methods: In this study, we investigated the influence of visual perceptual learning on non-directional motion processing using dynamic Glass patterns (GPs) and modified Random-Dot Kinematograms (mRDKs). We also explored the mechanisms of learning transfer to different stimuli and tasks. Specifically, we aimed to assess whether visual perceptual learning based on illusory directional motion, triggered by form and motion cues (dynamic GPs), transfers to stimuli that elicit comparable illusory motion, such as mRDKs. Additionally, we examined whether training on form and motion coherence thresholds improves internal noise filtering and sampling efficiency. Results: Our results revealed significant learning effects on the trained task, enhancing the perception of dynamic GPs. Furthermore, there was a substantial learning transfer to the non-trained stimulus (mRDKs) and partial transfer to a different task. The data also showed differences in coherence thresholds between dynamic GPs and mRDKs, with GPs showing lower coherence thresholds than mRDKs. Finally, an interaction between visual stimulus type and session for sampling efficiency revealed that the effect of training session on participants’ performance varied depending on the type of visual stimulus, with dynamic GPs being influenced differently than mRDKs. Conclusion: These findings highlight the complexity of perceptual learning and suggest that the transfer of learning effects may be influenced by the specific characteristics of both the training stimuli and tasks, providing valuable insights for future research in visual processing.Publicação Acesso Aberto The emotional movie database (EMDB): an expanded toolkit for emotion research2026-03-16 - Carvalho, Sandra; Coelho, Catarina Gomes; Mendes, Augusto J.; Gonçalves, Óscar F.; Leite, JorgeEmotion-eliciting film clips are widely used in psychological, neuroscientific, and affective computing research as standardized stimuli for the study of emotional responses. The Emotional Movie Database (EMDB) was originally developed to provide silent film clips for emotion research; however, limitations in stimulus diversity motivated its expansion. The present study extends the EMDB by introducing four additional emotional categories—social exclusion, social inclusion, unpleasant landscapes, and extreme sports—together with an expanded set of neutral film clips. Two complementary validation experiments were conducted. Experiment 1 (laboratory-based; n = 117) assessed social exclusion, social inclusion, unpleasant landscapes, and extreme sports clips, whereas Experiment 2 (web-based; n = 128) evaluated social exclusion, social inclusion, and newly recorded neutral clips. Participants rated each clip on valence, arousal, and dominance using the Self-Assessment Manikin (SAM) and reported the discrete emotions experienced. The results provide descriptive normative data for the newly added categories. Social exclusion clips were associated with negative valence (M = 2.16, SD = 1.07) and moderate-to-high arousal (M = 5.97, SD = 2.06), whereas social inclusion clips showed positive valence (M = 7.17, SD = 0.92) and moderate arousal (M = 4.68, SD = 1.72). Unpleasant landscape clips were rated as negatively valenced (M = 2.77, SD = 0.99) with relatively low arousal (M = 4.53, SD = 2.01). Extreme sports clips showed positive valence (M = 6.25, SD = 1.12) and intermediate arousal (M = 5.34, SD = 1.95). Newly recorded neutral clips consistently elicited near-neutral valence (M = 5.11, SD = 0.42) and low arousal (M = 2.31, SD = 1.36), supporting their use as baseline control stimuli. This work provides initial validation evidence and descriptive norms for an expanded set of EMDB film clips, broadening the affective space covered by the database and supporting its use in experimental research on emotion across laboratory-based and online settings.Publicação Acesso Aberto Mind-wandering facilitates creative performance in a musical improvisation task2026-04-01 - Palhares, Pedro T.; Branco, Diogo; Gonçalves, Óscar F.Mind-wandering is widely assumed to impair ongoing task performance, yet findings from creative cognition research suggest that it can be beneficial under some conditions — an inconsistency rooted in coarse mental state classifications and low-ecological-validity tasks. We tested whether mind-wandering during active creative production facilitates or impairs real-time creative output in the ecologically valid setting of live jazz improvisation. 52 musicians performed a musical improvisation task while random thought-probes sampled ongoing mental states: focused attention, mind-wandering, mind-blanking, and task-related interference. Expert judges rated each performance for creativity and overall improvisational quality. Mental states were phenomenologically distinct across dimensions of intentionality and meta-awareness, and critically, this phenomenological heterogeneity translated into functional heterogeneity in their associations with creative output. Mind-wandering predicted higher creativity than focused attention, task-related interference suppressed creativity, and mind-blanking was neutral to modestly positive. Overall quality was mainly driven by expertise. State × expertise interactions revealed that the creative benefits of mind-wandering were strongest for less- and mid-experienced improvisers. These findings show that during improvisatory creative action, mind-wandering need not derail performance. Instead, it may mark adaptive loosening of cognitive control that supports generative spontaneity and flexibility crucial to creative expression.
