Formal Timing Analysis of Mixed Music Scores

Interactive music systems coordinate in real-time an artificial perception of dynamics of human musicians with timely execution of machine reactions. As every human performance will differ from another, it is a challenging task to be able to predict the behavior or such systems in response to any possible performance, and prevent unwanted outcomes. We present here the application of formal models and methods from the real-time systems verification literature to the static analysis of interactive music systems. We consider in particular the good parameters problem, which consists in synthesizing a set of timing parameter valuations (representing performances here) guarantying a good behavior of the system analyzed. The methods presented have been applied to the system Antescofo, and are general enough to apply to other interactive music systems

A narrative review of interventions addressing the parental-fetal relationship

Background Expectant parents develop varying degrees of emotional affiliation with the unborn child. Interventions supporting this relationship may be beneficial given its link to maternal health behaviour during pregnancy, as well as the parental–infant bond after birth. Aim To identify and describe the effects of programmes and strategies that have addressed the parental–fetal relationship. Method English-language primary studies, published between 2005–2015, were identified and their methodological quality was assessed. Databases used included CINAHL, Cochrane Library, MEDLINE, PsycINFO and Web of Science. Key search terms included maternal/paternal–fetal attachment, prenatal bond, parental–fetal relationship and intervention. RCTs, non-RCTs, observational and non-comparative studies, before and after studies and case studies were included. Findings Twenty-seven papers were included. Studies evaluated the effects of various strategies, including ultrasound and screening procedures, fetal awareness interventions, social and psychological support techniques, educational programmes and relaxation strategies. Results are inconsistent due to the diversity of interventions and significant variation in methodological quality. Conclusion There is insufficient evidence to support definitive conclusions regarding the efficacy of any included intervention. A number of limitations, such as non-probability sampling, lack of blinding, and insufficient follow-up weaken the evidence. The inclusion of fathers in only three studies reflects the overall neglect of men in research regarding the prenatal relationship. Further in-depth study of the nature of the maternal/paternal–fetal relationship may be needed in order to allow for the identification of interventions that are consistently beneficial and worthwhile

Tapping to a slow tempo in the presence of simple and complex musical meters reveals experience-specific biases for processing music

Musical meters vary considerably across cultures, yet relatively little is known about how culture-specific experience influences metrical processing. In Experiment 1, we compared American and Indian listeners\u27 synchronous tapping to slow sequences. Inter-tone intervals contained silence or to-be-ignored rhythms that were designed to induce a simple meter (familiar to Americans and Indians) or a complex meter (familiar only to Indians). A subset of trials contained an abrupt switch from one rhythm to another to assess the disruptive effects of contradicting the initially implied meter. In the unfilled condition, both groups tapped earlier than the target and showed large tap-tone asynchronies (measured in relative phase). When inter-tone intervals were filled with simple-meter rhythms, American listeners tapped later than targets, but their asynchronies were smaller and declined more rapidly. Likewise, asynchronies rose sharply following a switch away from simple-meter but not from complex-meter rhythm. By contrast, Indian listeners performed similarly across all rhythm types, with asynchronies rapidly declining over the course of complex- and simple-meter trials. For these listeners, a switch from either simple or complex meter increased asynchronies. Experiment 2 tested American listeners but doubled the duration of the synchronization phase prior to (and after) the switch. Here, compared with simple meters, complex-meter rhythms elicited larger asynchronies that declined at a slower rate, however, asynchronies increased after the switch for all conditions. Our results provide evidence that ease of meter processing depends to a great extent on the amount of experience with specific meters

Age and schooling effects on early literacy and phoneme awareness

Previous research on age and schooling effects is largely restricted to studies of children who begin formal schooling from the age of 6 and the measures of phoneme awareness used have typically lacked sensitivity for beginning readers. Our study addresses these issues by testing children aged 4-6 (first two years of formal schooling in the UK) on a sensitive dynamic measure of phoneme awareness and tests of early literacy. There were significant effects of both age and schooling on dynamic and static measures of phoneme awareness, word reading, spelling and letter-name knowledge but no significant age × time interactions. This indicates that older children within this age group generally outperform their younger classmates (although they do not make faster progress), and that this advantage is developed prior to the start of school

Attachment preference in auditory German sentences: Individual differences and pragmatic strategy

Relative clauses modify a preceding element, but as this element can be flexibly located, the point of attachment is sometimes ambiguous. Preference for this attachment can vary within languages such as German, yet explanations for differences in attachment preference related to cognitive strategies or constraints have been conflicting in the current literature. The present study aimed to assess the preference for relative clause attachment among German listeners and whether these preferences could be explained by strategy or individual differences in working memory or musical rhythm ability. We performed a sentence completion experiment, conducted post hoc interviews, and measured working memory and rhythm abilities with diagnostic tests. German listeners had no homogeneous attachment preference, although participants consistently completed individual sentences across trials according to the general preference that they reported offline. Differences in attachment preference were moreover not linked to individual differences in either working memory or musical rhythm ability. However, the pragmatic content of individual sentences sometimes overrode the general syntactic preference in participants with lower rhythm ability. Our study makes an important contribution to the field of psycholinguistics by validating offline self-reports as a reliable diagnostic for an individual’s online relative clause attachment preference. The link between pragmatic strategy and rhythm ability is an interesting direction for future research

Continuous Interaction with a Virtual Human

Attentive Speaking and Active Listening require that a Virtual Human be capable of simultaneous perception/interpretation and production of communicative behavior. A Virtual Human should be able to signal its attitude and attention while it is listening to its interaction partner, and be able to attend to its interaction partner while it is speaking – and modify its communicative behavior on-the-fly based on what it perceives from its partner. This report presents the results of a four week summer project that was part of eNTERFACE’10. The project resulted in progress on several aspects of continuous interaction such as scheduling and interrupting multimodal behavior, automatic classification of listener responses, generation of response eliciting behavior, and models for appropriate reactions to listener responses. A pilot user study was conducted with ten participants. In addition, the project yielded a number of deliverables that are released for public access
