Dynamic structures of parent-child number talk: An application of categorical cross-recurrence quantification analysis and companion to Duong et al. (2024) [PDF]
Tutorials in Quantitative Methods for PsychologySocial interactions, particularly parent-child conversations, play a critical role in children’s early learning and pre-academic skill development. While these interactions are bidirectional, complex, and dynamic, much of the research in this area tends ...

Cross recurrence quantification analysis of precision grip following peripheral median nerve block [PDF]
Journal of NeuroEngineering and Rehabilitation, 2013 Precision grip by the thumb and index finger is vulnerable to sensorimotor deficits. Traditional biomechanical parameters offer limited insight into the dynamical coordination between digits during precision grip. In this study, the thumb and index finger were viewed as "coupled systems", and a cross recurrence quantification analysis (CRQA) was used ...

Measuring Coupling of Rhythmical Time Series Using Cross Sample Entropy and Cross Recurrence Quantification Analysis [PDF]
Computational and Mathematical Methods in Medicine, 2017 The aim of this investigation was to compare and contrast the use of cross sample entropy (xSE) and cross recurrence quantification analysis (cRQA) measures for the assessment of coupling of rhythmical patterns. Measures were assessed using simulated signals with regular, chaotic, and random fluctuations in frequency, amplitude, and a combination of ...
