Show summary
Ensemble musicians engage with each other visually through glances and body motion. We conducted a case study to test how string quartet musicians would respond to playing conditions that were meant to discourage or promote visually communicative behaviour. A quartet performed in different seating configurations under rehearsal and concert conditions. Quantity of head motion was reduced when musicians’ gaze was constrained. Differences in gaze and body motion between musicians reflected their musical roles in the ensemble. Overall, our findings suggest that gaze and motion dynamics vary within and between performances in response to changing musical, situational and social factors.

Music performance can be cognitively and physically demanding. These demands vary across the course of a performance as the content of the music changes. More demanding passages require performers to focus their attention more intensity, or expend greater “mental effort.” To date, it remains unclear what effect different cognitive-motor demands have on performers' mental effort. It is likewise unclear how fluctuations in mental effort compare between performers and perceivers of the same music. We used pupillometry to examine the effects of different cognitive-motor demands on the mental effort used by performers and perceivers of classical string quartet music. We collected pupillometry, motion capture, and audio-video recordings of a string quartet as they performed a rehearsal and concert (for live audience) in our lab. We then collected pupillometry data from a remote sample of musically-trained listeners, who heard the audio recordings (without video) that we captured during the concert. We used a modelling approach to assess the effects of performers' bodily effort (head and arm motion; sound level; performers' ratings of technical difficulty), musical complexity (performers' ratings of harmonic complexity; a score-based measure of harmonic tension), and expressive difficulty (performers' ratings of expressive difficulty) on performers' and listeners' pupil diameters. Our results show stimulating effects of bodily effort and expressive difficulty on performers' pupil diameters, and stimulating effects of expressive difficulty on listeners' pupil diameters. We also observed negative effects of musical complexity on both performers and listeners, and negative effects of performers' bodily effort on listeners, which we suggest may reflect the complex relationships that these features share with other aspects of musical structure. Looking across the concert, we found that both of the quartet violinists (who exchanged places halfway through the concert) showed more dilated pupils during their turns as 1st violinist than when playing as 2nd violinist, suggesting that they experienced greater arousal when “leading” the quartet in the 1st violin role. This study shows how eye tracking and motion capture technologies can be used in combination in an ecological setting to investigate cognitive processing in music performance.

Moving to music is a universal human phenomenon, and previous studies have shown that people move to music even when they try to stand still. However, are there individual differences when it comes to how much people spontaneously respond to music with body movement? This article reports on a motion capture study in which 34 participants were asked to stand in a neutral position while listening to short excerpts of rhythmic stimuli and electronic dance music. We explore whether personality and empathy measures, as well as different aspects of music-related behaviour and preferences, can predict the amount of spontaneous movement of the participants. Individual differences were measured using a set of questionnaires: Big Five Inventory, Interpersonal Reactivity Index, and Barcelona Music Reward Questionnaire. Liking ratings for the stimuli were also collected. The regression analyses show that Empathic Concern is a significant predictor of the observed spontaneous movement. We also found a relationship between empathy and the participants’ self-reported tendency to move to music.

The present study tested two assumptions concerning the auditory processing of microtiming in musical grooves (i.e., repeating, movement-inducing rhythmic patterns): 1) Microtiming challenges the listener's internal framework of timing regularities, or meter, and demands cognitive effort. 2) Microtiming promotes a “groove” experience—a pleasant sense of wanting to move along with the music. Using professional jazz musicians and nonmusicians as participants, we hypothesized that microtiming asynchronies between bass and drums (varying from −80 to 80 ms) were related to a) an increase in “mental effort” (as indexed by pupillometry), and b) a decrease in the quality of sensorimotor synchronization (as indexed by reduced finger tapping stability). We found bass/drums-microtiming asynchronies to be positively related to pupil dilation and negatively related to tapping stability. In contrast, we found that steady timekeeping (presence of eighth note hi-hat in the grooves) decreased pupil size and increased tapping performance, though there were no conclusive differences in pupil response between musicians and nonmusicians. However, jazz musicians consistently tapped with higher stability than nonmusicians, reflecting an effect of rhythmic expertise. Except for the condition most closely resembling real music, participants preferred the on-the-grid grooves to displacements in microtiming and bass-succeeding-drums-conditions were preferred over the reverse.

Previous research has shown that during recognition of frontal views of faces, the preferred landing positions of eye fixations are either on the nose or the eye region. Can these findings generalize to other facial views and a simpler perceptual task? An eye-tracking experiment investigated categorization of the sex of faces seen in four views. The results revealed a strategy, preferred in all views, which consisted of focusing gaze within an ‘infraorbital region’ of the face. This region was fixated more in the first than in subsequent fixations. Males anchored gaze lower and more centrally than females.

Two patients (TC and SS) with lesions that included the hippocampal regions (predominantly on the left side) were severely impaired in their recall of simple, verbally stated facts. However, both patients remembered spatial information that was temporally associated with semantic information. Specifically, TC and SS could not recall explicitly the content of an episode, but their spontaneous oculomotor behavior showed that they retained some information about the event as their gaze automatically returned to the locations on the computer screen where visual information had been paired to verbally presented information. Thus, this spatial information is implicit, automatically retrieved, and eye-based, as when one patient (TC) was asked to point with the finger to the same positions he was impaired. In addition, in an old/new recognition task, TC and SS and an additional patient, OB, showed significant changes in eye pupil diameter when viewing novel visual stimuli compared to stimuli that they had previously seen, also when they (incorrectly) declared with confidence that an old item was new. The spared memory of these patients, despite severe amnesia for the learning episodes, is characterized by a re-enactment of previous eye fixations that were associated with each (forgotten) episode and physiological responses (as indexed by pupillometry) to previously seen stimuli. Such spared memory can be seen as a type of ‘‘snapshot’’ memory, which automatically processes eye-based spatial information and whose content remains implicit. Finally, we surmise on the basis of the neuroanatomical findings of these patients, that neural substrates in the spared (right) hemisphere might support both the eye fixations’ re-enactment and implicit visual pattern recognition

Women's sexual preferences can change over the hormonal cycle, as several studies, based on responses to questionnaires, diaries, and ratings of photographs, have indicated increased sexual interests around the time of ovulation. However, fewer studies have measured changes in attention or interest to sexually significant stimuli in terms of physiological responses that are not under voluntary control and measure sexual interest indirectly (i.e., without mention of sexual feelings or activities). In the present study, we indexed changes in sexual interest in terms of changes in the eye pupil's size. Pupillary diameter is known to have a proportional relation to the observer's level of interest and attention to a visual stimulus as well as to physical pleasure. Fourteen women (7 being “pill” users) viewed photos on a computer screen while their pupil diameters were recorded using an infrared eye-tracking device. Three measures were taken for each participant during three time windows that estimated the ovulatory, luteal, and menstrual phase of the cycle. We found an increase in mean pupil diameter for sexually significant stimuli during the fertile phase and this pupillary change was also specific to pictures of the participants' actual sexual partners. Moreover, this effect was only seen for women who did not use oral contraceptives. These findings confirm that women's attention for sexually significant stimuli is higher during their fertile phase of the menstrual cycle, and that changes in sexual interest are implicitly measurable using pupillometry

Touch is a key means of interpersonal communication. The hormone oxytocin has been closely linked with affectionate touch. In this preliminary study, we investigate how altering the emotional expression and identity of visually perceived human faces may affect the hedonic experience of soft stroking touch. Conversely, the effects of social touch upon face perception are investigated. Finally, this study uses intranasal oxytocin administration (40IU) to elucidate the role of this hormone for social touch. Images of angry, neutral and happy facial expressions were chosen from the Karolinska Directed Emotional Faces database. In addition, two types of “hybrid” faces that showed anger or happiness only in the lowest spatial frequencies (1-6 cycles/image) and a neutral expression in the rest of the bandwidth (7-128 cycles/image) were used. Faces in the five emotion conditions were of the same 20 men and 20 women and were matched for luminance. Images were displayed in a pseudorandomised order for 3 sec and accompanied by touch (soft strokes of 3cm/sec to the forearm) or control stimulation (70Hz vibration presented once/sec to the dorsum of the hand). To avoid bias, the experimenter performing touch and vibration stimuli wore a silk glove and was hidden from view. The outcome measures of this double-blind, placebo-controlled within-subjects study were pupil diameter and subjective ratings of touch and face perception. Three main hypotheses were tested in this preliminary investigation. 1) Socially relevant seen emotion affects perception of social touch. 2) Pupil size reflects the pleasantness and subjective relevance of social touch. 3) Social touch and oxytocin affect perception of human face stimuli. The significance of preliminary findings was assessed with one-tailed, paired t-tests. As hypothesized, pilot data (N=9) showed an effect of socially relevant seen emotion on perception of touch pleasantness (but not touch intensity). When subjects viewed angry faces, touch pleasantness (6.0±0.4, mean±SD) was significantly lower than with neutral (6.2±0.4, p=0.033) or happy face stimuli (6.4±0.4, p=0.028). Overall, soft stroking was significantly more pleasant than the control stimulus (p=0.018) but both were equally intense (p=0.44) during oxytocin and placebo sessions (N=5). As expected, pupil size increased during pleasant, social touch relative to control stimulation (mean diameter difference 0.04±0.02 mm, p=0.032). Finally, there was a trend towards reduced ratings of perceived anger during social touch in the oxytocin session only (p=0.056; placebo session p=0.33), consistent with an anxiety-reducing effect of oxytocin and social touch.
