Are text comprehension and calculation processes in word problem solving sequential or interactive? An eye-tracking...

Area of Science:

• Cognitive Psychology
• Educational Psychology
• Developmental Psychology

Background:

• Word problem difficulty is influenced by linguistic and arithmetic factors.
• The interplay between these processes (sequential vs. interactive) remains debated.
• Limited research exists on eye-movement behavior during word problem solving with varying task characteristics.

Purpose of the Study:

• To investigate how linguistic and arithmetic task characteristics affect eye-movement behavior in children solving word problems.
• To determine if text comprehension and calculation processes are sequential or interactive.

Main Methods:

• Monitored eye movements of children aged 10-13 years during word problem solving.
• Manipulated linguistic factors (consistency, nominalization) and arithmetic factors (operation type).
• Analyzed eye movements in relation to numerical and textual elements of the problems.

Main Results:

• Increased linguistic or arithmetic difficulty led to increased overall eye movements.
• Arithmetic difficulty shifted eye movements towards numerical elements; linguistic difficulty shifted them towards textual elements.
• Increased arithmetic difficulty also increased processing of textual elements, suggesting interaction.

Conclusions:

• Text comprehension and calculation in word problem solving are not strictly separate or sequential.
• These processes appear to interact and may share cognitive resources.
• Eye-movement analysis provides insights into the cognitive mechanisms underlying word problem solving.
