This thesis examined the relationship between temperament and developmental stuttering, focusing on attention and inhibitory control. Three research objectives guided the studies. A temperament questionnaire revealed children who stutter (CWS) had higher negative reactivity and lower self-regulation than children who do not stutter (CWNS). Neuropsychological tasks assessed attentional networks and inhibitory control. CWS showed lower orienting network efficiency and struggled with endogenous response inhibition while performing comparably on externally triggered tasks. Overall, CWS differed from CWNS in temperament, particularly in self-regulation and negative reactivity, offering insight into developmental stuttering and paving the way for future longitudinal research.
