Motivation modulates the effect of approach on implicit preferences

Area of Science:

• Cognitive Psychology
• Social Psychology
• Neuroscience

Background:

• Implicit preferences, or unconscious biases, influence behavior and decision-making.
• Motivational states, such as hunger and thirst, are known to affect cognitive processes.
• The interplay between internal states and the formation of automatic preferences requires further investigation.

Purpose of the Study:

• To investigate whether motivational states modulate the formation of implicit preferences.
• To examine the influence of thirst and hunger on implicit preference for approached stimuli.
• To compare the effects of motivational states on implicit versus explicit preferences.

Main Methods:

• Three studies were conducted using behavioral tasks involving approach and avoidance.
• Participants engaged in activities where they approached one of two similar items (beverages or chips) while disregarding the other.
• Motivational states were manipulated (hunger) or measured (thirst, hours since last food intake).

Main Results:

• A significant implicit preference for the approached item emerged across all three studies.
• This implicit preference was modulated by participants' motivational states: thirst and hunger amplified the effect.
• The moderation effect by motivational states was observed for implicit preferences but not for explicit preferences.

Conclusions:

• Motivational states play a crucial role in shaping implicit preferences.
• Bodily needs can enhance the formation of automatic positive biases towards stimuli.
• Implicit and explicit preference systems may be differentially affected by internal motivational states.
