Hormonal and modality specific effects on males' emotion recognition ability

Area of Science:

• Neuroscience
• Psychology
• Endocrinology

Background:

• Emotion recognition is vital for social communication.
• Factors influencing emotion recognition accuracy in males are not well understood.
• Hormonal influences, specifically testosterone and cortisol, are potential moderators.

Purpose of the Study:

• To investigate factors affecting emotion recognition accuracy in males.
• To examine the impact of stimulus modality (voice, face, audio-visual) on accuracy.
• To explore the association of baseline testosterone and cortisol levels with emotion recognition performance.

Main Methods:

• 282 males participated in the study.
• Participants categorized nonverbal emotional content from voice, face, and audio-visual stimuli.
• Accuracy and reaction times were recorded; hormone levels (testosterone, cortisol) were measured.

Main Results:

• Audio-visual stimuli significantly improved emotion recognition accuracy compared to unimodal stimuli.
• Testosterone showed a potential positive association with recognition accuracy.
• Cortisol was linked to reaction time, and a significant, though small, interaction effect between testosterone and cortisol was observed for accuracy and reaction time.

Conclusions:

• Congruent audio-visual stimuli enhance emotion recognition in males.
• The interaction between testosterone and cortisol influences males' accuracy and response times in emotion recognition tasks.
• This study provides novel insights into the neuroendocrine underpinnings of male socio-emotional processing.
