When nudgees become nudgers: Exploring the use of self-nudging to promote fruit intake.

The current study explored (1) the immediate and prolonged effects of self-nudges promoting fruit intake in the home environment, (2) whether the effect of self-nudges on fruit intake persists after self-nudges are no longer used (i.e. a temporal spillover effect) and (3) whether self-nudges can install healthy eating habits that, in turn, explain the temporal spillover effect.

The effect of transparency on the temporal spillover effect of default nudges.

Previous studies show that the effects of (non-transparent) nudges can spill over to later similar decisions without nudges. In the current study, we aimed to determine whether such nudge temporal spillover effects are affected by making nudges transparent. The latter is recommended to (partly) mitigate ethical concerns surrounding the use of nudges.

The Effects of Nudges: One-Shot Only? Exploring the Temporal Spillover Effects of a Default Nudge.

Nudges, such as defaults, are generally found to be effective in guiding immediate behavioural decisions. However, little is known about whether the effect of a nudge can be lasting, meaning that it spills over to subsequent similar choices without the presence of a nudge. In three experiments, we explored the temporal spillover effects of a default nudge.

Nudging healthy eating in Dutch sports canteens: a multi-method case study.

Objective: To provide a micro-investigation into the long-term effects and process of implementation of a nudge intervention on food choice in sports canteens.

Design: Multi-method case study.

Setting: Eight products were added to the range of foods and drinks in two football canteens in the Netherlands for 3 and 15 weeks, serving as a baseline period.
