Distinct developmental trajectories for explicit and implicit timing.

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Neuroscience

Background:

• Explicit timing involves conscious awareness of temporal intervals.
• Implicit timing occurs without conscious temporal processing.
• Cognitive capacity influences explicit timing performance in children.

Purpose of the Study:

• To investigate age-related differences in explicit and implicit timing.
• To examine the role of cognitive capacity in timing tasks.
• To determine if explicit and implicit timing have distinct developmental trajectories.

Main Methods:

• Participants aged 5, 8, and adults completed explicit and implicit timing tasks.
• Neuropsychological tests assessed participants' cognitive capacities.
• Temporal variability was measured as performance spread around a reference interval.

Main Results:

• Temporal variability decreased with age in explicit timing tasks.
• Younger children (5-year-olds) showed higher temporal variability linked to lower cognitive capacity.
• Implicit timing variability remained constant across ages and was independent of cognitive capacity.

Conclusions:

• Explicit and implicit timing exhibit different developmental patterns.
• Cognitive development significantly impacts explicit time perception.
• Implicit time processing appears independent of age and cognitive capacity in early development.
