La acción social ante la crisis global
2010
La crisis global exige profundas mutaciones en todos los subsistemas de la sociedad, y requiere de nuevas conceptualizaciones, mapas conceptuales y transiciones técnicas en el ámbito de la intervención social. A partir de las convulsiones del Estado de Bienestar, de las reducciones presupuestarias, del aumento de las demandas en situación de emergencia, de las exigencias de la cultura actual del derecho y de los procesos de mundialización, se recrea el lugar de la acción social: como atención a las privaciones, despliegue de las capacidades y fomento de la acción conjunta. Asimismo, se necesita abrir la acción social a distintos actores: al Estado con sus administraciones, al mercado con su…
You cannot speak and listen at the same time: a probabilistic model of turn-taking.
2017
Turn-taking is a preverbal skill whose mastering constitutes an important precondition for many social interactions and joint actions. However, the cognitive mechanisms supporting turn-taking abilities are still poorly understood. Here, we propose a computational analysis of turn-taking in terms of two general mechanisms supporting joint actions: action prediction (e.g., recognizing the interlocutor's message and predicting the end of turn) and signaling (e.g., modifying one's own speech to make it more predictable and discriminable). We test the hypothesis that in a simulated conversational scenario dyads using these two mechanisms can recognize the utterances of their co-actors faster, wh…
Analyzing multidimensional movement interaction with generalized cross-wavelet transform
2021
Humans are able to synchronize with musical events whilst coordinating their movements with others. Interpersonal entrainment phenomena, such as dance, involve multiple body parts and movement directions. Along with being multidimensional, dance movement interaction is plurifrequential, since it can occur at different frequencies simultaneously. Moreover, it is prone to nonstationarity, due to, for instance, displacements around the dance floor. Various methodological approaches have been adopted for the study of human entrainment, but only spectrogram-based techniques allow for an integral analysis thereof. This article proposes an alternative approach based upon the cross-wavelet transfor…
A Coupled Oscillator Model of Interactive Tapping
2009
Background: Synchronization in music has been a popular experimental basis for studying social interactions, as musicians are required to synchronize to each other’s beats and integrate abstract social information in order to coordinate their actions as part of a non-verbal communication process. A finger-tapping paradigm has been used in studies of sensorimotor synchronization as well as coordination dynamics within and between people (Repp 2005). Recent models of tapping dynamics have included two error-correction mechanisms: phase and period correction (Repp & Keller). They have generally been linear models, which are oversimplifications of these dynamics. Aims: To model the dynamics cap…

Sensorimotor Coarticulation in the Execution and Recognition of Intentional Actions
2017
Humans excel at recognizing (or inferring) another's distal intentions, and recent experiments suggest that this may be possible using only subtle kinematic cues elicited during early phases of movement. Still, the cognitive and computational mechanisms underlying the recognition of intentional (sequential) actions are incompletely known and it is unclear whether kinematic cues alone are sufficient for this task, or if it instead requires additional mechanisms (e.g., prior information) that may be more difficult to fully characterize in empirical studies. Here we present a computationally-guided analysis of the execution and recognition of intentional actions that is rooted in theories of m…
Sensorimotor Communication for Humans and Robots: Improving Interactive Skills by Sending Coordination Signals
2018
During joint actions, humans continuously exchange coordination signals and use nonverbal, sensorimotor forms of communication. Here we discuss a specific example of sensorimotor communication-"signaling"-which consists in the intentional modification of one's own action plan (e.g., a plan for reaching a glass of wine) to make it more predictable or discriminable from alternative action plans that are contextually plausible (e.g., a plan for reaching another glass on the same table). We first review the existing evidence on signaling in human-human interactions, discussing under which conditions humans use signaling. Successively, we distill these insights into a computational theory of sig…
Investigating cognitive mechanisms of social interaction through musical joint action
2016
Contagion, Empathy and Theory of Mind (ToM) are important social cognitive mechanisms that develop gradually in human ontogeny, enabling humans to interact with other human beings in a complex manner. However, the development of cognitive mechanisms for early social interaction is still underexplored. Therefore, the aim of the current paper is to investigate these mechanisms in a broader range from a theoretical as well as empirical perspective. In particular, we propose a musiccentered approach, which allows us to investigate cognitive mechanisms of social interaction independently of children’s language skills in a musical joint action setting. In our theoretical part, we delineate the so…
Social effects of interpersonal synchronization during listening to music compared to a metronome: What can we learn from implicit measures?
2016
Interpersonal coordination, such as simultaneous rhythmic movement, is a fundamental way to form socioemotional connections. The social and emotional power of music might further strengthen such interpersonal bonds. Here, we tested if interpersonal synchronization (synchronous vs. asynchronous finger-tapping) affects sympathy and helpfulness more strongly when listening to music compared to a metronome. We tested 40 participants and used an explicit and an implicit measure to assess their social orientation toward a tapping partner (i.e., one of two experimenters). Participants directly rated the friendliness of the experimenter on a 9-point Likert scale. As a more indirect or implicit meas…
