dc.description.abstract | Investigaciones previas han determinado que los Tiempos de Reacción (TR) correspondientes a diferentes tareas neurocognitivas se distribuyen como una función exgaussiana, es decir una combinación entre una función exponencial y una normal. Estudios recientes muestran que los parámetros μ y σ de la distribución corresponden a los procesos perceptuales y motores, mientras que el parámetro τ corresponde al proceso de toma de decisiones involucrado en dichas tareas. El presente estudio tiene como fin determinar si existen cambios significativos asociados a la edad (adultos jóvenes vs adultos) en alguno de los parámetros μ, τ y σ obtenidos de los TR correspondientes a una tarea de aprendizaje contextual ajustados a una distribución exgaussiana. Para ello se utilizó una tarea de aprendizaje contextual denominada “Contextual Cueing Task”; los TR de la tarea se ajustaron a la distribución exgaussiana usando la toolbox DISTRIB en Matlab, obteniéndose los tres parámetros correspondientes a dicha función μ, σ, τ. Esta tarea fue aplicada a 20 participantes (8 mujeres) con edades entre 19 a 43 años, con quienes se conformaron dos grupos de estudio; el primero Adultos jóvenes (n=10) con edades entre 19 a 26 años, y el segundo Adultos (n=10) con participantes de 27 a 43 años. Los resultados mostraron la edad y el contexto no ejerce un efecto significativo sobre los parámetros μ, σ, τ de la función exgaussiana. | spa |

dc.description.abstractenglish | Previous research has determined that the corresponding Reaction Times (TR) to different neurocognitive tasks are distributed as an ex-Gaussian function, that is, a combination between an exponential and a normal function. Recent studies show that parameters μ and σ of the distribution correspond to the perceptual and motor processes, while that the parameter τ corresponds to the decision-making process involved in these tasks. The purpose of this study is to determine if there are significant changes associated with the age (young adults vs adults) in any of the parameters μ, τ and σ obtained from the TR corresponding to a contextual learning task adjusted to an ex-Gaussian distribution. For this, a contextual learning task called “Contextual Cueing Task” was used; The TRs of the task were fitted to the ex-Gaussian distribution using the DISTRIB toolbox in Matlab, obtaining the three parameters corresponding to said function μ, σ, τ. This task was applied to 20 participants (8 women) aged between 19 to 43 years, with whom they formed two study groups; the first Young adults (n = 10) aged 19 to 26 years, and the second Adults (n = 10) with participants aged 27 to 43 years. The results showed the age and context do not have a significant effect on the parameters μ, σ, τ of the function ex-Gaussian. | eng |
