Exploratory behaviour and executive functions: A relationship that can be manipulated?

ABSTRACT This thesis examined the possibility of a relationship between exploratory behaviour and executive functions (i.e. cognitive development) in 137 children (76 boys and 61 girls (Mpre = 5.3 years; SD = .6; Mpost = 6.3 years; SD = .6)). Additionally, the effect of an intervention, aimed at improving children’s executive functioning, on their exploratory behaviour was examined using a pretest posttest intervention design. This question was tested on a sample of 247 children containing 137 boys and 110 girls (Mpre = 5.3 years; SD = .6; Mpost = 6.3 years; SD = .6). Parents were randomly assigned to the intervention- or control group. Parents of forty children were trained on how to stimulate their children’s social- and cognitive functioning, with a major focus on executive functioning, and parents of 207 children were not. Executive functions are known to be trainable and believed to be related to the development of exploratory behaviour.

This question was tested on a sample of 247 children containing 137 boys and 110 girls (Mpre = 5.3 years; SD = .6; Mpost = 6.3 years; SD = .6). Parents were randomly assigned to the intervention- or control group. Parents of forty children were trained on how to stimulate their children’s social- and cognitive functioning, with a major focus on executive functioning, and parents of 207 children were not. Executive functions are known to be trainable and believed to be related to the development of exploratory behaviour. Playhouse, a newly developed task, assesses the quality of exploration. The executive functions; inhibition, working memory and attention, were measured with the Amsterdam Psychological Tasks. The results suggest that a relationship between children’s executive functioning and their quality of exploratory behaviour exists. However, these relationships had a small effect. Additionally, it was found that children’s executive functioning and quality of exploratory behaviour depend on their age. However, it remains unclear whether the improved executive functions with increasing age affect the increasing quality of exploratory behaviour with increasing age. Furthermore, the results in this study suggest that training parents to stimulate their children’s social- and cognitive functioning, with a major focus on executive functioning does not affect their quality of exploratory behaviour. Further research in this area is necessary in order to get a more accurate understanding of the relationship between children’s executive functioning and their explorative behaviour, and the psychometric properties of Playhouse.Show less
