Resumen
The general aim of this thesis is to evaluate the behavioural and neurophysiological influence of Predictive and Non-predictive Reward strategies offered in a game, Temperament and Sex, on Inhibitory Control in children aged 4 to 5 years. In order to approach the subject, a state of the art on children's self-regulation skills, their developmental milestones and the intervening factors (first article) was elaborated. The methodological design used was a cross-sectional, non-experimental and correlational design that considered 149 children aged 4 to 5 years. The instruments used were 2 Tablet games designed for the study and a child temperament questionnaire. For this questionnaire, a psychometric analysis was carried out on a sample of the Chilean population (second article). The empirical part of the study was conducted in two stages, firstly, a behavioural measurement of the participating children was conducted (third article), and secondly, the neural correlate of inhibitory control in the presence of both types of reward was assessed in a subsample of 16 children. The main findings indicate that the influence of different types of rewards on inhibitory control in the sample studied responds differently to older age groups. It is also mentioned that temperament and gender influence inhibitory response. Finally, the paper concludes with an integrated synthesis of the results obtained, discussing the contribution of the study, its implications, limitations and future projections.
