Challenges in this area can be exacerbated in individuals with depression and anxiety, potentially leading to social exclusion in severe cases. The purpose of this study was to examine (1) the influence of different facial expressions on the perceiver\u2019s motivational states and (2) whether negative cognitive biases associated with depression and anxiety affect these states. These states were measured using brain\u2019s relative left frontal alpha asymmetry (rLFA) in electroencephalography (EEG) signals, a marker of approach (positive rLFA) or withdrawal (negative rLFA) motivation in brain. While rLFA reflects stable motivational tendencies, it also varies dynamically in response to stimuli. Prior research suggests that viewing angry faces enhances approach motivation, while viewing sad faces reduces it, with neutral faces serving as a baseline. This study, conducted at the University of Jyv\u00e4skyl\u00e4 as part of the Multiface project, involved 21 participants (16 female) assessed for depression and trait anxiety symptoms using the DASS-42 -questionnaire. Unlike earlier research relying on photographs or videos, this study employed a live model to present angry, sad, and neutral expressions in a naturalistic setting. \nA correlation analysis revealed a strong positive linear relationship across the three facial expressions. However, neither a one-sample t-test nor a repeated-measures analysis of variance showed significant differences in rLFA from zero or among expressions. As a result, the expected approach-inducing effect of angry faces and the approach-reducing effect of sad fac-es were not observed. Additionally, no significant correlation was found between rLFA and symptoms of trait anxiety or depression. This pioneering study underscores the need for further neuroimaging research using live human faces to better understand the motivational mechanisms underlying facial expression perception and related biomarkers in depression and anxiety.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2025-02-20T11:01:18Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2025-02-20T11:01:18Z (GMT).
