Tapping to hip-hop: Effects of cognitive load, arousal, and musical meter on time experiences

(Abstract) Experiences of time vary intra- and interindividually, depending on factors such as attentional resource allocation and arousal. Music as a temporal art that is structured by multiple temporal layers is ideal for investigating human time experiences. The current study used examples of hip-hop music that varied in arousal but were constant in tempo. Participants judged the passage of time to be quicker when cognitive load was high in a dual-task condition, and perceived duration to be shorter when performing a concurrent motor task (tapping along with the music). Perceived musical arousal did not affect subjective time. Attending to a higher metrical level by tapping with half notes resulted in shorter duration estimates and a quicker passage of time, compared to tapping with eighth notes of the same music. Results were not influenced by spontaneous motor tempo, musical expertise, preference or familiarity with the music. Taken together, these findings indicate consistent effects of cognitive load and attention to meter on time experiences.

Data from: Disruption of the ascending arousal network in acute traumatic disorders of consciousness

Objective: To determine whether ascending arousal network (AAN) connectivity is reduced in patients presenting with traumatic coma. Methods: We performed high angular resolution diffusion imaging (HARDI) in 16 patients with acute severe traumatic brain injury who were comatose on admission and in 16 matched controls. We used probabilistic tractography to measure the connectivity probability (CP) of AAN axonal pathways linking the brainstem tegmentum to the hypothalamus, thalamus and basal forebrain. To assess the spatial specificity of CP differences between patients and controls, we also measured CP within four subcortical pathways outside the AAN. Results: Compared to controls, patients showed a reduction in AAN pathways connecting the brainstem tegmentum to a region of interest encompassing the hypothalamus, thalamus, and basal forebrain. Examining each pathway individually, brainstem-hypothalamus and brainstem-thalamus CPs, but not brainstem-forebrain CP, were significantly reduced in patients. Only one subcortical pathway outside the AAN showed reduced CP in patients. Conclusions: We provide initial evidence for the reduced integrity of axonal pathways linking the brainstem tegmentum to the hypothalamus and thalamus in patients presenting with traumatic coma. Our findings support current conceptual models of coma as being caused by subcortical AAN injury. AAN connectivity mapping provides an opportunity to advance the study of human coma and consciousness.

Perceiving arousal and valence in facial expressions: Differences between children and adults

Arousal and valence have long been studied as the two primary dimensions for the perception of emotional stimuli such as facial expressions. Prior correlational studies that tested emotion perception along these dimensions found broad similarities between adults and children. However, few studies looked for direct differences between children and adults in these dimensions beyond correlation. We tested 9-year-old children and adults on rating positive and negative facial stimuli based on emotional arousal and valence. Despite high significant correlations between children’s and adults’ ratings, our findings also showed significant differences between children and adults in terms of rating values: Children rated all expressions as significantly more positive than adults in valence. Children also rated positive emotions as more arousing than adults. Our results show that although perception of facial emotions along arousal and valence follows similar patterns in children and adults, some differences in ratings persist, and vary by emotion type.

Perception of valence and arousal in German emotion terms – A comparison between 9-year-old children and adults

Two major semantic features of emotion concepts have been shown to impact performance in emotion perception tasks: valence and arousal. To design psycholinguistic experiments with emotion terms as stimuli, norms are required which indicate valence and arousal values for individual words. Although such norms are usually obtained from ratings of adults, they are often also used in developmental studies. This procedure raises the question of whether children and adults perceive emotional valence and arousal of words in the same way, and consequently, whether adults’ ratings are adequate when constructing stimulus sets for children. The present study obtained valence and arousal ratings for 48 German emotion terms from three different groups: 9-year-old children and adults tested in a controlled laboratory setting, and adults tested via online survey. Results demonstrate high correlations for valence and arousal across settings. The comparison between children and adults also revealed high correlations, suggesting that children at the age of 9 already display adult-like behavior in their evaluation of emotion terms. A small difference was found for absolute rating values of arousal, with children rating words less arousing than adults. Overall, using adults’ norms in developmental studies on word processing seems to be a valid procedure.

Audio-visual perceived arousal in music performance

This dataset and R code are are linked to the manuscript: Järveläinen, H. Sound-accompanying movements enhance perceived arousal in music performance even from a distance. Proc. Sound and Music Computing conference SMC, Saint-Etienne, France, June 2022, (in press). The dataset Odf.RData contains functional measurements of perceived arousal in music performance, and the respective INLA model fit. The measurements are based on three-minute recordings from a solo piece for the English horn as specified in the article.
