Estimate and confidence intervals around effect size ds of the comparison between non-anthropomorphism and sad-anthropomorphism in Experiments 1, 2, and 3.

Note. Effect sizes from Ahn et al. are drawn from Study 1 for campaign evaluation and Study 2 for anticipated guilt. Positive effects reflect comparisons in which the sad-anthropomorphism mean was higher than the non-anthropomorphism mean. Experiment 1–3 confidence interval values, which appear in brackets, represent 95% confidence intervals based on the noncentral t distribution [57], using guidelines outlined by Wuensch [58]. Note also that effect sizes and confidence intervals for Experiment 1 were calculated from between-condition independent-sample t-tests in light of the requirement for corresponding degrees of freedom requirements for noncentral t confidence interval estimation. Meta-analyzed effect sizes and respective 95% confidence intervals are based on Experiments 1–3 (see Meta-Analytic Summary of Experiments).Estimate and confidence intervals around effect size ds of the comparison between non-anthropomorphism and sad-anthropomorphism in Experiments 1, 2, and 3.
