The Beauty of the Zero : Replications and Extensions of the Hidden-Zero Effect in Delay Discounting Tasks
Unlike the presentation format in a typical delay discounting task (e.g., "Would you prefer [A] US$4.3 today OR [B] US$7.5 in 22 days?"), Magen et al. inserted a zero to each alternative (e.g., "Would you prefer [A] US$4.3 today and US$0 in 22 days OR [B] US$0 today and US$7.5 in 22 d...

Zusammenfassung: | Unlike the presentation format in a typical delay discounting task (e.g., "Would you prefer [A] US$4.3 today OR [B] US$7.5 in 22 days?"), Magen et al. inserted a zero to each alternative (e.g., "Would you prefer [A] US$4.3 today and US$0 in 22 days OR [B] US$0 today and US$7.5 in 22 days?") and found this manipulation effectively reduced delay discounting (d= .84), which was referred to as the hidden-zero effect. Study 1 was a direct replication of this effect. In Study 2, we tested whether the explicit-zero format could buffer against the detrimental effect of exposure to sexy cues on delay discounting. In Study 3, we explored the mechanism underlying the hidden-zero effect. Taken together, the hidden-zero effect was consistently found across all studies (N= 2,440) and our internal meta-analysis yielded a medium to large effect size (d= .52). |
