A thesis is an aptitude test for students. The approval of the thesis is proof that the student has sufficient research and reporting skills to graduate but does not guarantee the quality of the research and the results of the research as such, and the thesis is therefore not necessarily suitable to be used as an academic source to refer to. If you would like to know more about the research discussed in this thesis and any publications based on it, to which you could refer, please contact the supervisor mentioned.
Abstract
This study investigated the developmental patterns of intelligence, emotional intelligence (EI), and motor skills in children and adolescents aged 4.4 to 21.6 years, with a focus on the influence of socioeconomic status (SES). Using data from 1,474 German-speaking participants across Germany, Austria, and Switzerland, and employing Generalized Additive Models for Location, Scale, and Shape (GAMLSS), the study modeled both linear and non- linear growth trajectories. Results indicated that intelligence followed a linear development pattern, while EI and motor skills showed significant non-linear trajectories. SES had a strong and stable influence on intelligence and gross motor skill development, but little to no effect on fine and visuomotor skills or EI. Notably, the correlation between intelligence and EI remained significant after controlling for age, particularly within the low SES group, suggesting stronger developmental interdependence. The findings highlight the complex, domain-specific nature of child and adolescent development and emphasize the role of SES in shaping developmental outcomes. Keywords: intelligence, emotional intelligence, motor skills, socioeconomic status, child development, GAMLSS
