A minimal ingroup advantage in emotion identification confidence

Area of Science:

• Psychology
• Social Psychology
• Cognitive Science

Background:

• Accurate emotion expression decoding is vital for social interaction.
• Perceiver confidence, not just accuracy, impacts social functioning.
• Previous research linked ingroup advantage in emotion recognition to cultural familiarity.

Purpose of the Study:

• To investigate if an ingroup advantage in emotion decoding confidence exists beyond cultural boundaries.
• To explore the role of social-cognitive processes in this ingroup advantage.
• To determine if arbitrary group membership influences both accuracy and confidence in emotion recognition.

Main Methods:

• Two experiments were conducted using distinct sets of facial emotion stimuli.
• Participants labeled emotion expressions and reported their confidence levels.
• Minimal ingroup membership was manipulated while keeping cultural context constant.

Main Results:

• Participants demonstrated higher accuracy in decoding emotion expressions from minimal ingroup members.
• Participants reported significantly greater confidence when decoding ingroup expressions.
• Both accuracy and confidence showed an ingroup advantage, irrespective of cultural background.

Conclusions:

• Ingroup advantages in emotion decoding confidence are not solely dependent on cultural familiarity.
• Social-cognitive factors contribute significantly to the ingroup advantage in emotion recognition confidence.
• Arbitrary group affiliations can elicit biases in emotion perception and confidence.
