Fear recognition ability predicts differences in social cognitive and neural functioning in men

Area of Science:

• Neuroscience
• Social Cognition
• Psychology

Background:

• Facial fear recognition is crucial for social interaction.
• Amygdala damage can impair fear recognition.
• Individual differences in social cognition exist within the general population.

Purpose of the Study:

• To investigate the prevalence and implications of impaired facial fear recognition in men.
• To test if poor fear recognition predicts deficits in other social cognition domains.
• To examine neural underpinnings of social information processing in individuals with and without fear recognition deficits.

Main Methods:

• Tested facial fear recognition in 341 men.
• Administered psychological tests for social cognition (e.g., theory of mind).
• Utilized functional magnetic resonance imaging (fMRI) to compare brain activity in low vs. normal fear scorers during face perception tasks.

Main Results:

• 8.8% of men showed impaired fear recognition.
• Low fear scorers (LFS) performed worse on theory of mind tests compared to normal fear scorers (NFS).
• fMRI revealed reduced amygdala, fusiform gyrus, and anterior superior temporal cortex activation in LFS viewing direct gaze faces, with absent amygdala-anterior temporal cortex connectivity.

Conclusions:

• Significant individual differences in social cognitive skills are present in healthy men.
• Compromised neural systems for social information processing may underlie these differences.
• Impaired fear recognition is associated with broader social cognition deficits and altered brain function.
