Behavioral synchrony has been linked to endorphin activity (Cohen et al., 2010; Sullivan and Rickers, 2013; Sullivan et al., 2014; Tarr et al., 2015, 2016; Weinstein et al., 2016). This has been called the synchrony effect. Synchrony has two dominant phases of movement; in-phase and anti-phase. The majority of research investigating synchrony's effect on endorphin activity has focused on in-pha...

Ongoing interactions among cortical neurons often manifest as network-level synchrony. Understanding the spatiotemporal dynamics of such spontaneous synchrony is important because it may (1) influence network response to input, (2) shape activity-dependent microcircuit structure, and (3) reveal fundamental network properties, such as an imbalance of excitation (E) and inhibition (I). Here we de...

Previous research has shown that the matching of rhythmic behaviour between individuals (synchrony) increases cooperation. Such synchrony is most noticeable in music, dance and collective rituals. As well as the matching of behaviour, such collective performances typically involve shared intentionality: performers actively collaborate to produce joint actions. Over three experiments we examined...

Human communication is a dynamical and interactive process that naturally induces an active flow of interpersonal coordination, and synchrony, along various behavioral dimensions. Assessing and characterizing the temporal dynamics of synchrony during an interaction is essential for fully understanding the human communication mechanisms. In this work, we focus on uncovering the temporal variabil...

During the 1980s, the North Sea plankton community underwent a well-documented ecosystem regime shift, including both spatial changes (northward species range shifts) and temporal changes (increases in the total abundances of warmer water species). This regime shift has been attributed to climate change. Plankton provide a link between climate and higher trophic-level organisms, which can forag...

Many biological populations fluctuate in synchrony over large geographic regions. This behavior may increase the chance of extinction. The combination of time-scale separation between interacting species and weak spatial linear diffusive coupling is one mechanism that can generate synchrony; however, accounting for travel time between habitat patches may destabilize this synchrony. Here, we sho...

BACKGROUND Assessment of mother-child interactions is a core issue of early child development and psychopathology. This paper focuses on the concept of "synchrony" and examines (1) how synchrony in mother-child interaction is defined and operationalized; (2) the contribution that the concept of synchrony has brought to understanding the nature of mother-child interactions. METHOD Between 1977...

Rhythmic synchronization phenomena in interpersonal communication are classified into two, based on its temporal aspect and behavioural form similarity aspect. We focus on the temporal aspect, movement synchrony, the gestalt-like perception of movement rhythmicity or coordination. With the aid of THEME, we aim to describe it based on statistical definition of objective behavioural data. Behavio...

Repeated spike patterns have often been taken as evidence for the synfire chain, a phenomenon that a stable spike synchrony propagates through a feedforward network. Inter-spike intervals which represent a repeated spike pattern are influenced by the propagation speed of a spike packet. However, the relation between the propagation speed and network structure is not well understood. While it is...

Researchers from various disciplines are concerned with the study of affective phenomena, especially arousal. Expressed affective modulations, which reflect both an individual’s internal state and external factors, are central to the communicative process. Bone et al. developed a robust, unsupervised (rule-based) method which provides a scale-continuous, bounded arousal rating from the vocal si...
