Fig 1. Effect sizes across Studies 1 and 2.

Effect sizes for the enjoyment (green) and emotional amplification (red) of shared experiences are centered on zero, while participants effect sizes for participants’ motivation to choose shared experiences (blue) are consistently large. Standardized effect estimates: Cohen’s d (Studies 1a, 1b, 1d; Studies 2a-c, Valuation), Cohen’s d (Study 1c) and standardized regression coefficients (Studies 2a-c, Enjoyment). 95% confidence intervals were calculated via bootstrapping (Studies 1a-d, Studies 2a-c, Valuation), or by assuming a quadratic log-likelihood surface (Wald-Method; Studies 2a-c, Enjoyment).
