A and B: relationship between mean percentage change in number-pair bisection error induced by the combined visuo-vestibular stimulation paradigm (x-axis) compared with the corresponding caloric alone condition and change in mean monetary amount donated during the dictator game task (y-axis). A: a negative correlation was observed during RIGHTCOLD + RIV stimulation, which biases participants toward smaller magnitudes. That is, individuals that manifested larger biases toward smaller number manifested a proportional change in decisions during the dictator game (i.e., became correspondingly less generous). B: conversely, during LEFTWARM + RIV which induces biases toward larger magnitudes resulted in increased monetary donations during the dictator game. C and D: %change in mean monetary amount donated for each individual, negative during the RIGHTCOLD + RIV condition (reflecting less generosity; C) and positive during the LEFTWARM + RIV condition (reflecting increased generosity; D).
