Este estudio siguió un enfoque basado en procesos, en el que la variabilidad describe los cambios que ocurren momento a momento. El objetivo de este estudio es explorar las trayectorias intraindividuales del uso conjunto del cardinal numérico y la notación de cantidades. Veintitrés niños en edad preescolar de 4-5 años participaron en el estudio. Los niños asistían a la escuela pública en Cali-Colombia. En cuanto al método, se utilizó un diseño microgenético y una tarea denominada “Dar y anotar un número” para capturar la variabilidad. De la actuación de los niños. La tarea fue una adaptación de la tarea “Dar un número” de LeCorre y Carey (2007). Para el análisis de datos se implementó la técnica de análisis de conglomerados. Los resultados revelaron algunos patrones de las trayectorias intraindividuales del desempeño de los niños: (1) cinco patrones de cardinalidad, (2) cinco patrones de notaciones y (3) varios perfiles conjuntos para “dar” y “anotar” cantidades. En conclusión, nuestros hallazgos sugieren un proceso dinámico de uso conjunto de la cardinalidad y las notaciones, mostrando la coexistencia de diferentes niveles de complejidad. |

The aim of this study is to explore the intra-individual trajectories of the joint use of the numerical cardinal and the notation of quantities. Twenty-three preschool children of 4-5 years old participated on the study. The children were attending public school in Cali-Colombia. Regarding the method, a microgenetic design and a task called “Give and Note a Number” was used to capture the variability of the children’s performance. The task was an adaptation of the task “Give a Number” by LeCorre and Carey (2007). The technique of cluster analysis was implemented for data analysis. The results revealed some patterns of the intra-individual trajectories of the children’s performance: (1) five patterns of cardinality, (2) five patterns of notations, and (3) several joint profiles to“give” and “note” quantities. In conclusion, our findings suggest a dynamic process of the joint use of the cardinality and notations,showing the co-existence of different levels of complexity.brehmert.martinez@campusucc.edu.co2070-2089Universidad Cooperativa de Colombia, Facultad de Ciencias Sociales, Psicología, CaliPsicologíaCalihttps://www.journalppw.com/index.php/jppw/article/view/13875Journal of Positive Psychology & WellbeingBassano, D., & van Geert, P.
