Depressive Tendency Biases Ensemble Perception of Emotional Faces

Area of Science:

• Cognitive Psychology
• Affective Science
• Neuroscience

Background:

• Individuals with depression show deficits in encoding single facial expressions.
• The impact of subclinical depressive tendencies on perceiving average emotions from multiple faces is largely unknown.

Purpose of the Study:

• To investigate if depressive tendencies influence explicit and implicit ensemble perception of emotion.
• To determine how varying exposure durations affect emotion perception in individuals with high and low depressive symptoms.

Main Methods:

• Study 1: Participants with high depressive symptoms (HDS) and low depressive symptoms (LDS) judged emotion in face sets (2000ms vs. 50ms exposure).
• Study 2: Assessed automatic ensemble emotion perception using a probe identification task under similar exposure conditions.

Main Results:

• HDS group showed a bias toward anger in explicit perception at 2000ms, but not at 50ms.
• Both HDS and LDS groups exhibited similar automatic (implicit) coding of ensemble emotion across exposure times.

Conclusions:

• Depressive tendencies can selectively bias explicit ensemble emotion perception.
• Implicit, automatic processing of ensemble emotion is not affected by depressive tendencies.
