Key result
Codependent individuals exhibited an ambivalent emotional response and reduced recognition of emotional tone for visual and auditory stimuli compared to healthy controls.
Why the study?
The emotional disturbances of individuals with codependency are often ignored, prompting an investigation into their emotional perception across visual, auditory, tactile, and olfactory modalities.
Cross-Sectional (n=30)
No
Codependent individuals exhibit altered emotional perception and EEG responses, particularly in visual and auditory modalities, suggesting a neurophysiological basis for their emotional dysregulation.

Small EEG study of emotional perception in codependency; leaves open clinical relevance pending larger replication.
The emotional disturbances of individuals with codependency are often ignored. This study aimed to investigate the emotional perception of codependent individuals in four modalities – visual, auditory, tactile and olfactory. An EEG study was performed and presented pleasant and unpleasant stimuli selected by a panel of experts for each modality. Participants (fifteen codependent individuals and fifteen healthy volunteers) were instructed to assess the emotional impact and pleasantness of stimuli. The method of EEG spaces was used to visualize how close perceived stimuli were according to EEG data. The results showed ambivalence of emotional response to emotional stimuli with social component and lack of recognition of emotional tone detected in EEG and behavioral levels. The empathy feeling in codependent individuals was detected for fewer emotional stimuli. The group differences were associated with evolutionary newer modalities (auditory and visual). The lack of emotional perception in codependent subjects was determined by social factors and was detected in visual and auditory modalities, which were more involved in social interactions than olfactory and tactile modalities.

Portnova et al. (2023) conducted a cross-sectional in Codependency (n=30). Codependency vs. Healthy volunteers was evaluated on Difference in subjective pleasantness and EEG indexes between pleasant and unpleasant stimuli. Codependent individuals exhibited an ambivalent emotional response and reduced recognition of emotional tone for visual and auditory stimuli compared to healthy controls.
