Visualising future behaviour: Effects for snacking on biscuit bars, but no effects for snacking on fruit.

Area of Science:

• Behavioral Science
• Cognitive Psychology
• Nutrition Psychology

Background:

• Dietary choices significantly impact public health.
• Understanding psychological interventions to promote healthy eating is crucial.
• Visualization techniques are explored as potential tools for behavior modification.

Purpose of the Study:

• To investigate the effect of visualizing snacking on fruit versus biscuit bars on subsequent consumption intentions and behaviors.
• To determine if the specific content of visualized behavior influences its effectiveness.
• To assess the role of background variables in the efficacy of visualization interventions.

Main Methods:

• A randomized controlled trial with 223 participants.
• Three groups: visualizing fruit snacking, visualizing biscuit bar snacking, and a control (no visualization).
• Measured intentions, attitudes, immediate selection, and consumption of fruit and biscuit bars.

Main Results:

• Visualizing fruit snacking showed no significant effect on fruit intentions or consumption after accounting for background variables.
• Visualizing biscuit bar snacking led to significantly greater intentions to consume biscuit bars (β = 0.19, p < 0.01).
• Effectiveness of visualization appears dependent on the specific behavior being visualized.

Conclusions:

• The specific content of visualized behaviors is a critical factor in their psychological impact.
• Visualization of unhealthy snack consumption may inadvertently increase intentions to consume those snacks.
• Further research is required to determine if visualization can be effectively tailored to promote healthy eating, such as increased fruit consumption.
