Official title
Changing Quantitative Reasoning Across Development
Overview
The goal of this study is to understand the cognitive processes underlying quantitative and relational reasoning, including the understanding of mathematical information (e.g., numbers, proportions, percentages, geometry) and related relational concepts (e.g., analogies, the concepts same/different), as well as how people's reasoning can be changed by external factors. The main question it aims to answer is: How does the introduction of a secondary task affect the behavior of children and adults when reasoning about proportions in different formats? Participants will be asked to make judgements about images with and without the presence of a distractor task.
Interventions
- Behavioral Verbal Interference Task
During the second half of the study, participants will undergo an interference task such as repetition of the word "the"; or shadowing a radio broadcast in order to increase cognitive load and disrupt the use of a mental workspace.
Primary outcome measures
- Overall Performance [Time frame: After enrollment in a single study session]
