The Look that Binds: Partner-Directed Altruistic Motivation and Biased Perception in Married Couples

Area of Science:

• Social Psychology
• Cognitive Psychology
• Relationship Science

Background:

• Facial trustworthiness is often linked to positive personality traits and elicits positive social responses.
• It remains unclear if perceiving someone as having benign motivations influences their perceived facial trustworthiness.

Purpose of the Study:

• To investigate whether altruistic motivation towards a partner influences the perception of their facial trustworthiness.
• To explore the reciprocal relationship between motivational processes and perceptual mechanisms in relationships.

Main Methods:

• Elderly married couples completed questionnaires assessing altruistic motivation, accommodative behaviors, marital satisfaction, and trust.
• Participants later performed a face-processing task using spousal and stranger faces.

Main Results:

• Higher motivation to prioritize a spouse's well-being predicted perceiving the spouse's neutral face as more trustworthy.
• Other relationship functioning variables did not predict perceived facial trustworthiness.

Conclusions:

• Motivational processes, specifically altruistic motivation, can shape basic perceptual mechanisms related to facial trustworthiness.
• This finding highlights a reciprocal dynamic influencing relationship climates.
