The possibilities of the psychosemantic method in the study of social anhedonia in patients with schizophrenia
Bibliographic record
Abstract
The results of a study of social anhedonia in patients with schizophrenia are presented. The subject of the study is social anhedonia in patients with schizophrenia. The purpose of the work: to conduct a theoretical analysis of the possibilities of the psychosemantic approach and to present empirical data on the features of the subjective semantic structure of social experience in patients with schizophrenia, its links with the severity of social anhedonia and the characteristics of social motivation. It clarifies that patients with schizophrenia with pronounced social anhedonia show active social avoidance, instead of the expected indifference. Special attention is paid to the psychosemantic approach, which makes it possible to describe the structure of subjective semantic coordinates of social experience in patients with schizophrenia and to identify its relationship with motivation for social avoidance. The study involved 42 patients aged 23 to 46 years (mean age = 34.8 years, SD = 7.4) with a diagnosis of "F20.0 paranoid schizophrenia" with more than 5 years of illness, in a state of subremission, without pronounced psychotic symptoms. Adapted methods "Scale of social anhedonia" (Eckblad et al., 1982), "Scale of social avoidance and distress" (D. Watson, R. Friend, 1969), "A brief scale of fear of negative social assessment" (M. Leary, 1983), "The Toronto scale of alexithymia" (G. Taylor, J. Parker, R. Bagby, 1994); SPSS Statistics program ver.22. It has been revealed that social anhedonia in patients with schizophrenia is associated with the peculiarities of the subjective semantic structure of social experience; patients with schizophrenia, regardless of the available characteristics and context, characterize others as evil and malevolent, which leads them to the inability to enjoy social interaction; these features mediate motivation for social avoidance, and also prevent the acquisition of emotional experience from an actual situation of social interaction. The novelty of the results lies in the application of a psychosemantic method, namely a directed associative experiment, in which subjects were consistently presented with images representing photographs of the eyes of professional actors expressing various emotional states. The results obtained complement previous studies in the field of social motivation of patients with schizophrenia. Scope of the results: development and implementation of psychocorrective and psychotherapeutic programs.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
