Serial dependence (SD) shows how past experiences influence current perceptions. This study reveals that while stimulus bias is stable, response bias strengthens with age, developing fully in adulthood.
Area of Science:
- Cognitive Neuroscience
- Developmental Psychology
- Perception
Background:
- Serial dependence (SD) describes how prior stimuli and responses bias current perception.
- SD aids in stabilizing perception by reducing sensory noise, but its developmental course is unclear.
Purpose of the Study:
- To investigate the developmental trajectories of stimulus and response biases in serial dependence across different age groups.
- To differentiate the developmental paths of stimulus-based and response-based biases within SD.
Main Methods:
- Utilized generalized linear mixed-effects (GLME) modeling to analyze stimulus and response biases simultaneously.
- Compared GLME analysis with conventional separate analyses of previous stimulus and response biases.
- Examined three age groups to track developmental changes in SD.
Main Results:
- Previous stimulus bias (repulsion) remained stable across age groups.
- Previous response bias (attraction) was significantly weaker in children and adolescents compared to adults.
- GLME analysis revealed distinct developmental trajectories for stimulus and response biases, outperforming separate analyses.
Conclusions:
- The repulsion bias from preceding stimuli is established early in development (by ~10 years old).
- The attraction bias related to responses matures later, reaching adult levels in adulthood.
- These findings illuminate the developmental integration of opposing mechanisms in perceptual processing.
