Tracking the Development of Post-Error Slowing in Arithmetic: Longitudinal Patterns from Childhood to Adolescence
SymposiumTalk-05
Presented by: Eveline Jacobs
Adaptive post-error adjustments are critical for learning and performance. They allow individuals to modify their behavior after making a mistake with the goal to improve task outcomes. These adjustments are typically studied in highly controlled laboratory tasks, such as Flanker or Stroop tasks. Much less is known about how people implement post-error adjustments in ecologically relevant academic contexts, such as arithmetic, where such adjustments may reflect strategic, metacognitive processes. Moreover, their developmental trajectory remains underexplored, leaving questions about how children of various ages and adolescents differ in their capacity to adapt following errors unanswered. The present longitudinal study examined post-error slowing (PES) during arithmetic performance across three age groups: 7-8-year-olds (n = 114), 10-11-year-olds (n = 102), and 13-14-year-olds (n = 99). Participants completed the same arithmetic task at two time points, approximately one year apart. Both cross-sectional and longitudinal results indicated reliable PES across all age groups, with a gradual decrease in magnitude throughout the primary school years. Although PES was consistently observed, its relationship with arithmetic performance was weak and limited to the youngest age group, suggesting that the functional significance of PES in arithmetic may be age-dependent. By examining PES in arithmetic, this study extends the investigation of post-error adjustments beyond laboratory paradigms, offering new insights into how children and adolescents adapt to mistakes in real-world academic tasks and how these processes develop with age.
