abstract = {Individuals with severe depressive symptoms present diminished facial expressions compared to
healthy individuals. This reduced facial expression, which occurs in most depressive patients could
impair social relationships. The current study sought to investigate whether pictures with social
interaction cues could elicit different modulations of facial expressions and mood states in individuals
with depressive symptoms compared to healthy individuals. A total of 85 individuals were divided into
depressive and non-depressive groups based on their beck depression inventory scores. Participants
viewed pictures containing neutral (objects), affiliative (people interacting socially), and control
(people not interacting) scenes. Electromyographic signals were collected during the entire period of
visualization of the blocks, and emotional questionnaires were evaluated after each block to assess
sociability and altruism (prosocial states). In non-depressed individuals, affiliative pictures increased
the activity of the zygomatic muscle compared to both neutral and control pictures and reduced fear
of rejection compared to neutral pictures. During the visualization of the affiliative block, zygomatic
major muscle activation was higher and fear of rejection was lower in the non-depressive individuals
than in the depressive. These effects reflected the low expressions of smiling and sociability to
affiliative pictures in depressive individuals. These findings highlight the importance of smiling and
prosocial states in social interactions, especially in these individuals.},
