The main question it aims to answer is:\n\nDo adults use a substitution heuristic when judging non-symbolic proportions, leading them to answer an easier, yet incorrect question?\n\nResearchers will compare performance at baseline with one of two conditions in order to see if forced behavioral changes can change performance on the task.\n\nParticipants will be asked to compare two images and judge which has the higher proportion of the target color. Each participant will also be assigned to one of two condition where they either receive a further incentive for correct selections or are required to use more time when making their calculations.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '64 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Typically developing people within the target age range\n\nExclusion Criteria:\n\n* Individuals with known developmental or cognitive disorders\n* Participants must speak/read sufficient English to read and complete the informed consent document'}, 'identificationModule': {'nctId': 'NCT06762366', 'briefTitle': 'Substitution Heuristic on Proportional Tasks', 'organization': {'class': 'OTHER', 'fullName': 'Rutgers, The State University of New Jersey'}, 'officialTitle': 'Substitution in Adult Proportional Reasoning', 'orgStudyIdInfo': {'id': 'Pro2024002168'}, 'secondaryIdInfos': [{'id': 'R00HD104990', 'link': 'https://reporter.nih.gov/quickSearch/R00HD104990', 'type': 'NIH'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Additional Incentive', 'description': 'In this arm of the experiment, participants will receive the additional incentive intervention.', 'interventionNames': ['Behavioral: Additional Incentive']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Response Delay', 'description': 'In this arm of the experiment, participants will receive the response delay intervention.', 'interventionNames': ['Behavioral: Response Delay']}, {'type': 'SHAM_COMPARATOR', 'label': 'Baseline Performance', 'description': 'In this arm of the study, participants will complete the task as it is typically administed.', 'interventionNames': ['Behavioral: Baseline Performance']}], 'interventions': [{'name': 'Additional Incentive', 'type': 'BEHAVIORAL', 'description': 'During this behavioral intervention, participants will be given additional compensation for correct answers.', 'armGroupLabels': ['Additional Incentive']}, {'name': 'Response Delay', 'type': 'BEHAVIORAL', 'description': 'During this behavioral intervention, participants will not be allowed to respond with their judgements until after a certain amount of time has passed.', 'armGroupLabels': ['Response Delay']}, {'name': 'Baseline Performance', 'type': 'BEHAVIORAL', 'description': 'In this intervention, the participant completes the task as it is typically administer for a baseline performance measure.
