A listener's aesthetic engagement with a musical piece often reaches peaks in response to passages experienced as especially beautiful. The present study examined the extent to which responses to such self-identified beautiful passages (BPs), in self-selected music, may be distinguishable in terms of their affective qualities. In an online survey, participants indicated pieces in which they considered specific passages to be outstandingly beautiful. In the lab, they listened to these pieces while physiological recordings were taken. Afterwards, they provided ratings on their experience of the BPs, where items targeted emotion response, underlying engagement mechanisms, and aesthetic evaluation. Cluster-analyses based on emotion ratings suggested three BP subtypes that we labelled low-Tension-low-Energy (LTLE), low-Tension-high-Energy (LTHE) and high-Tension-high-Energy (HTHE) BPs. LTHE and HTHE BPs induced greater interest and were more liked than LTLE BPs. Further, LTHE and HTHE clusters were associated with increases in skin-conductance, in accordance with the higher arousal reported for these BPs, while LTLE BPs resulted in the increases in smiling and respiration-rate previously associated with processing fluency and positive valence. LTLE BPs were also shown to be lower in tempo and polyphony than the other BP types. Finally, while both HTHE and LTHE BPs were associated with changes in dynamics, they nevertheless also showed distinct patterns whereby HTHE BPs were associated with increases in pitch register and LTHE BPs, with reductions in harmonic ambiguity. Thus, in line with our assumption that there is more than one kind of experience of musical beauty, our study reveals three distinct subtypes, distinguishable on a range of facets.

Body orientation of gesture entails social‐communicative intention, and may thus influence how gestures are perceived and comprehended together with auditory speech during face‐to‐face communication. To date, despite the emergence of neuroscientific literature on the role of body orientation on hand action perception, limited studies have directly investigated the role of body orientation in the interaction between gesture and language. To address this research question, we carried out an electroencephalography (EEG) experiment presenting to participants (n = 21) videos of frontal and lateral communicative hand gestures of 5 s (e.g., raising a hand), followed by visually presented sentences that are either congruent or incongruent with the gesture (e.g., “the mountain is high/low…”). Participants underwent a semantic probe task, judging whether a target word is related or unrelated to the gesture‐sentence event. EEG results suggest that, during the perception phase of handgestures, while both frontal and lateral gestures elicited a power decrease in both the alpha (8–12 Hz) and the beta (16–24 Hz) bands, lateral versus frontal gestures elicited reduced power decrease in the beta band, source‐located to the medial prefrontal cortex. For sentence comprehension, at the critical word whose meaning is congruent/incongruent with the gesture prime, frontal gestures elicited an N400 effect for gesture‐sentence incongruency. More importantly, this incongruency effect was significantly reduced for lateral gestures. These findings suggest that body orientation plays an important role in gesture perception, and that its inferred social‐communicative intention may influence gesture‐language interaction at semantic level.

Research on fine-grained dynamic psychological processes has increasingly come to rely on continuous self-report measures. Recent studies have extended continuous self-report methods to simultaneously collecting ratings on two dimensions of an experience. For all the variety of approaches, several limitations are inherent to most of them. First, current methods are primarily suited for bipolar, as opposed to unipolar, constructs. Second, respondents report on two dimensions using one hand, which may produce method driven error, including spurious relationships between the two dimensions. Third, two-dimensional reports have primarily been validated for consistency between reporters, rather than the predictive validity of idiosyncratic responses. In a series of tasks, the study reported here addressed these limitations by comparing a previously used method to a newly developed two-handed method, and by explicitly testing the validity of continuous two-dimensional responses. Results show that our new method is easier to use, faster, more accurate, with reduced method-driven dependence between the two dimensions, and preferred by participants. The validity of two-dimensional responding was also demonstrated in comparison to one-dimensional reporting, and in relation to post hoc ratings. Together, these findings suggest that our two-handed method for two-dimensional continuous ratings is a powerful and reliable tool for future research.

Body orientation of gesture entails social-communicative intention, and may thus influence how gestures are perceived and comprehended together with auditory speech during face-to-face communication. To date, despite the emergence of neuroscientific literature on the role of body orientation on hand action perception, limited studies have directly investigated the role of body orientation in the interaction between gesture and language. To address this research question, we carried out an EEG experiment presenting to participants (n=21) videos of frontal and lateral hand gestures of five-seconds (e.g., raising a hand), followed by visually presented sentences that are either congruent or incongruent with the hand gesture (e.g., 'the mountain is high/low…'). All participants underwent a semantic-probe task, judging whether a target word is related or unrelated to the gesture-speech event. EEG results suggest that, during the perception phase of handgestures, while both frontal and lateral gestures elicited power decrease in both the alpha (8-12Hz) and the beta (16-24Hz) bands, lateral gestures elicited reduced power decrease in the beta band when compared with frontal gestures. For sentence comprehension, at the critical word whose meaning is congruent/incongruent with the gesture, frontal gestures elicited an N400 effect for gesture-sentence incongruency. More importantly, this incongruency effect was significantly reduced for lateral gestures. The findings suggest that body orientation plays a crucial role in gesture perception, and that its inferred socialcommunicative intention influences gesture-sentence semantic integration in an interactive manner.
