Research Project
Full description Adolescence is a period of substantial cognitive development, yet relatively little is known about how the underlying cognitive processes that support goal-directed behaviour develop and interact during this period. This project examined individual differences in selective attention, inhibitory control, and decision-making in a cross-sectional sample of 253 typically developing adolescents aged 13-20 years. Participants completed a battery of behavioural tasks, including measures of visual attention, inhibitory control, delay discounting, and perceptual decision-making, alongside self-report measures of impulsivity. Computational modelling approaches were applied to estimate latent cognitive parameters underlying task performance, including attentional processing, inhibitory control, evidence accumulation, and decision thresholds. The project also aimed to characterise the latent structure of cognitive control during adolescence and identify which cognitive processes exhibit age-related variation. Findings contribute to understanding the development of cognitive control and provide a foundation for future investigations linking behavioural and computational measures to their underlying neural mechanisms.
