Incremental versus saturation hypotheses for behavioral nudge in reducing sugar consumption.

Objective: This field experiment examined the efficacy of a behavioral nudge intervention towards lowering sugar intake in Indonesia. Specifically, two competing hypotheses were tested as to whether behavioral nudge played an additive role (i.e.

BMI and explicit-implicit cues on food choice: The fake food buffet in the United Kingdom and Indonesia.

We examined whether people with high BMI sampled from two different countries were more susceptible to behavioural change via an implicit, rather than explicit, intervention. We measured BMI and used three types of cue interventions (implicit vs explicit healthy lifestyle cue vs neutral cue) to examine their impact on our participants' food choice using the Fake Food Buffet. Healthiness of the meal chosen was measured by the percentage of healthy food items in the meal.

The sociodemographic context of observed solitary and social smoking behaviours using a behavioural ecological approach.

This study used a behavioural ecological approach by observing whether solitary and social smoking varied as a function of gender and stress. In sample 1 ( = 414), the result was consistent with the tend-and-befriend hypothesis, in that more female smokers were observed to engage in social smoking during high stress. When the number of smokers observed by stress condition was controlled for in sample 2 ( = 587), this effect was non-significant.
