the behavioral data of Dual-task paradigm from GDT and BART under the Influence of social exclusion and cognitive load on risk decision making

The experimental program was presented on a 17 inch computer screen with a resolution of 1366 * 768. All levels of memory tasks, as well as BART and GDT paradigms, were presented using Eprime2.0, and their behavioral results were recorded. After the subjects enter the room, the main experimenter introduces the experimental content and requirements to them, obtains their informed consent, and enters the experimental stage. Randomly divide the participants into two groups: social exclusion group and social acceptance group, and then complete the online ball throwing task of each group and fill out the post cyberball questionnaire. Afterwards, we entered the risk decision-making behavior experiment and completed the BART paradigm under 2 numerical memory conditions, the BART paradigm under 4 numerical memory conditions, the GDT paradigm under 2 numerical memory conditions, and the GDT paradigm under 4 numerical memory conditions in the order of ABBA balance. Before each task begins, the participants are first presented with experimental instructions, and then three practice experiments are conducted to make them understand the experimental rules, sequence, and button reactions clearly. In the formal experiment, the GDT task included 36 dice guessing and 36 numerical memory judgment tasks, while the BART task included 48 balloon filling and 48 numerical memory judgment tasks. Descriptive statistical analysis was conducted on the recognition number response time, BART value, number of blown balloons, and GDT value of the rejection and acceptance groups under high and low cognitive loads. The mean and standard deviation of risk decision-making performance of the rejection and acceptance groups under different loads are shown in 4-1.
