Assessing selective sustained attention in 3- to 5-year-old children: evidence from a new paradigm

Area of Science:

• Cognitive Psychology
• Developmental Neuroscience
• Child Psychology

Background:

• Selective sustained attention (SSA) is vital for advanced cognitive functions.
• Existing research on developmental interactions between exogenous and endogenous attentional factors is limited.
• A lack of developmentally appropriate research paradigms hinders progress.

Purpose of the Study:

• To introduce and validate a novel research paradigm for investigating SSA in preschoolers.
• To examine the interplay of exogenous and endogenous factors on attentional control during early development.
• To provide a tool for differentiating attentional control mechanisms from task engagement.

Main Methods:

• Development of a novel, developmentally appropriate task for preschoolers.
• Psychometric and parametric evaluation of the new task.
• Application of the task to investigate SSA with both exogenous and endogenous factors.

Main Results:

• The novel task demonstrates good psychometric and parametric properties.
• The paradigm successfully allows for the simultaneous investigation of exogenous and endogenous attentional factors.
• Performance changes can be attributed to specific attentional control mechanisms.

Conclusions:

• The developed task is a valuable tool for studying SSA development in young children.
• This paradigm facilitates a nuanced understanding of how different attentional control mechanisms interact.
• Future research can utilize this task to explore developmental trajectories of attentional control.
