Engaging Mental Effort: Process- and Person-Based Reward Experiences, Effort Reinforcement Intervention, and Cascading Effects on Challenging Tasks (NCT07557732)

๐ŸŸข Recruiting Observational / Diagnostic ๐Ÿง  Behavioral & Psychological Program Sponsor: University of California, Davis

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

Brief Summary: The goal of this clinical trial is to investigate the influences of children's prior experiences with rewards following successes at school and interventions aimed at influencing children's preferences for challenging cognitive tasks. The main questions this study aims to answer are as follows: 1. Does the frequency of process-based rewards (e.g., rewards for working hard) vs. outcomes-based rewards (i.e., rewards for a good grade) predict children's preferences for challenging cognitive tasks? 2. Does providing rewards for taking on effortful cognitive tasks increase children's preferences for challenging cognitive tasks more than providing rewards for performing well on cognitive tasks? 3. Does receiving rewards for taking on effortful cognitive tasks increase children's challenge-seeking in novel tasks and questionnaires relevant for academic achievement that have not been previously linked with rewards? Participants will complete the following tasks: 1. A matrix completion problem solving task, with options to seek tips for solving problems and options to quit early. 2. A response inhibition task, with options to complete a harder or easier version of the task. 3. A cognitive flexibility task, with options to complete a harder or easier version of the task. 4. A puzzle completion task, with an option to quit early. 5. Answer a set of questions about academic effort 6. Parents will complete a set of questions about how they responded to children's recent successes and failures at school.
