Abstract Background and Purpose. By 3 to 4 months of age, infants born full-term and without known disease display associative learning and memory abilities in the mobile paradigm, where an infant's leg is tethered to a mobile such that leg kicks result in proportional mobile movement. The first purpose of this study was to examine the learning and memory abilities of a group of infants born full-term compared with those of a comparison group. Little is known about the learning and memory abilities in infants born preterm, a group at known risk for future impairments in learning and movement. The second purpose of this study was to determine if and when an age-adjusted group of infants born prematurely display associative learning and memory abilities over a 6-week period. Subjects. Ten infants born full-term (38–42 weeks gestational age [GA]) and 10 infants born preterm (<33 weeks GA and <2,500 g) who were tethered and had control over the mobile movement were independently compared with a comparison group of 10 infants born full-term who were tethered and viewed a moving mobile but did not have control over the mobile movement. Infants in all 3 groups were seen at 3 to 4 months of age and were excluded from participation for any known visual or orthopedic diagnoses. Methods. Infants were tested using the mobile conjugate reinforcement paradigm, where one leg is tethered to an overhead mobile such that kicking with that leg results in proportional mobile movement. The kicking rates of the full-term group and the preterm group were compared with their own initial (baseline) kicking rates and with those of the comparison group. Results. After exposure to the conjugate relationship between kicking and mobile movement, the full-term group kicked more frequently compared with their own baseline levels and compared with the comparison group, fulfilling both criteria for learning and memory. In contrast, the preterm group did not increase their kicking rate according to both criteria. Discussion and Conclusion. These results suggest that infants born prematurely differ in their performance in the mobile paradigm as compared with age-matched infants born full-term. The mobile paradigm may provide clinicians with an important early assessment of infants' associative learning and memory abilities. Follow-up studies are needed, however, to further validate this paradigm as a clinical assessment tool.

Zusammenfassung. Menschliche Entwicklung vollzieht sich in der Interaktion von Biologie und Kultur. Deshalb müssen die jeweiligen öko-kulturellen Kontextbedingungen bei der Untersuchung von Entwicklung berücksichtigt werden. Untersuchungen in verschiedenen öko-kulturellen Kontexten stellen jedoch große Anforderungen an die verwendeten Untersuchungsmethoden. In dem vorliegenden Überblicksartikel werden diese methodischen Herausforderungen dargestellt und anhand von empirischen Beispielen aus dem Bereich der Kulturvergleichenden Forschung zur Lern- und Gedächtnisentwicklung von Säuglingen verdeutlicht. Die Beispiele beziehen sich auf das Habituationsparadigma, die Mobile-Aufgabe (mobile conjugate reinforcement task) sowie die A-nicht-B-Suchaufgabe. Lösungsmöglichkeiten werden entwickelt und mögliche Forschungsstrategien diskutiert.

Zusammenfassung. Berichtet wird über eine Längsschnittstudie mit vier Untersuchungszeitpunkten an 87 Kindern im Alter von 3 bis 24 Monaten. Ziel war es, die Assoziationen zwischen Kompetenzen zur nicht-sozialen Kontingenzwahrnehmung mit drei und sechs Monaten und dem späteren Entwicklungsstand mit einem bzw. zwei Jahren sowie der sprachlichen Entwicklung mit zwei Jahren zu analysieren. Die Kompetenz zur Wahrnehmung nicht-sozialer Kontingenzen wurde mittels Mobile Conjugate Reinforcement Paradigma (Mobiletest) sowie Visual Expectation Paradigma (VEP) erhoben. Der Entwicklungsstand wurde mit dem Entwicklungstest 6 Monate - 6 Jahre (ET 6-6) erhoben, die sprachliche Entwicklung mittels des Sprachtests für zweijährige Kinder (SETK-2). Es zeigte sich, dass die Ergebnisse des Mobiletests mit drei Monaten signifikante Bezüge zur Sprachentwicklung mit zwei Jahren aufwiesen. Das VEP mit sechs Monaten stand ebenfalls mit der Sprachentwicklung mit zwei Jahren, zusätzlich aber auch mit der kognitiven und sozialen Entwicklung mit einem Jahr in Verbindung. Diskutiert werden neben der Notwendigkeit zu einer altersspezifischen Differenzierung zwischen den beiden Paradigmen zur Wahrnehmung nicht-sozialer Kontingenzen auch die möglichen Verbindungslinien zwischen nicht-sozialer Kontingenzwahrnehmung und Entwicklung.

Listening, a significant dimension of the behavior of hearing-impaired children, may be measured directly by recording childrens' responses to obtain audio narrations programmed via a conjugate reinforcement system. Twelve hearing-impaired, school-aged children responded in varying ways to the opportunity to listen. Direct and continuous measurement of listening has relevance for evaluation of remediation methods and for discovery of variables potentially related to listening.

In this paper we argue that our comprehension of musical participation—the complex network of interactive dynamics involved in collaborative musical experience—can benefit from an analysis inspired by the existing frameworks of dynamical systems theory and coordination dynamics. These approaches can offer novel theoretical tools to help music researchers describe a number of central aspects of joint musical experience in greater detail, such as prediction, adaptivity, social cohesion, reciprocity, and reward. While most musicians involved in collective forms of musicking already have some familiarity with these terms and their associated experiences, we currently lack an analytical vocabulary to approach them in a more targeted way. To fill this gap, we adopt insights from these frameworks to suggest that musical participation may be advantageously characterized as an open, non-equilibrium, dynamical system. In particular, we suggest that research informed by dynamical systems theory might stimulate new interdisciplinary scholarship at the crossroads of musicology, psychology, philosophy, and cognitive (neuro)science, pointing toward new understandings of the core features of musical participation.

Abstract Rhythmic joint coordination is ubiquitous in daily-life human activities. In order to coordinate their actions towards shared goals, individuals need to co-regulate their timing and move together at the collective level of behavior. Remarkably, basic forms of coordinated behavior tend to emerge spontaneously as long as two individuals are exposed to each other’s rhythmic movements. The present study investigated the dynamics of spontaneous dyadic entrainment, and more specifically how they depend on the sensory modalities mediating informational coupling. By means of a novel interactive paradigm, we showed that dyadic entrainment systematically takes place during a minimalistic rhythmic task despite explicit instructions to ignore the partner. Crucially, the interaction was organized by clear dynamics in a modality-dependent fashion. Our results showed highly consistent coordination patterns in visually-mediated entrainment, whereas we observed more chaotic and more variable profiles in the auditorily-mediated counterpart. The proposed experimental paradigm yields empirical evidence for the overwhelming tendency of dyads to behave as coupled rhythmic units. In the context of our experimental design, it showed that coordination dynamics differ according to availability and nature of perceptual information. Interventions aimed at rehabilitating, teaching or training sensorimotor functions can be ultimately informed and optimized by such fundamental knowledge.
