Elizabeth M. Payment, Lisa Emery & Erica Camp Decisions in the Dictator Game were dependent on offer types., and this finding was slightly more pronounced in the younger adults. Younger adults, in the DG, were influenced by picture age and gender, where as older adults were not. Although the correlations were non-significant due to the small sample size, there was a slight tendency for generativity to correlate positivity with DG offers to past participants, and for the CAII to correlate negatively with DG offers. Participants 30 young adults (15 men, 15 women, Ages 18-33; M=26.2 years) 13 older adults (4 men, 9 women; ages 60 – 73; M = 65.1 years) All participants were paid $10 for their participation.

Please type how much money you would like to split with this individual using the keyboard. The offers young adults made were influenced by the Age, Sex, and Offers of “Prior Participants”, F(3,81) = 15.63, p <.001, η p 2 =.37 The offers older adults made were only influenced by the Offers of “Prior Participants”, F(3,30) = 11.85, p <.001, η p 2 =.54 (Effect size for three-way interaction: η p 2.=.06) Older and Younger adults made equivalent offers to “Future Participants”, and this did not vary across conditions. This research is part of Elizabeth Payment’s Senior Honors Thesis, and was supported by an Office of Student Research Grant from Appalachian State University, and a WiSE award from the Department of Psychology. Correlations with Motivational & Cognitive Variables *Age difference significant at p <.01 Additional reprints may be obtained at Agelabs.appstate.edu Design: 2 (Picture Age: Young vs. Old) x 2 (Picture Sex: Female vs. Male) x 4 (Previous Offer Type: Fair, Slightly Unfair, Moderately Unfair, Very Unfair) Previous research shows that older adults sometimes make less profitable decisions in financial games like the Ultimatum game and the Dictator game, in that older adults tend to make more generous offers when serving as the “proposer” than do young adults (Bailey et al., 2012). These differences in financial decisions between older and younger adults could be attributable to changes in motivation. Here, we report pilot data from a version of the Dictator Game in which participants made offers to “Prior Participants”, and were given information on the offers that these prior participants made.
