This study investigates the speech articulatory coordination in schizophrenia subjects exhibiting strong positive symptoms (e.g. hallucinations and delusions), using a time delay embedded correlation analysis. We show that the schizophrenia subjects with strong positive symptoms and who are markedly ill pose complex coordination patterns in facial and speech gestures than what is observed in healthy subjects. This observation is in contrast to what previous studies have shown in Major…

Multimodal Approach for Assessing Neuromotor Coordination in Schizophrenia Using Convolutional Neural Networks

TLDR
The best performing multimodal network improves the mean F1 score for detecting schizophrenia by around 18% with respect to the full vocal tract coordination (FVTC) baseline method implemented with fusing FAUs and MFCCs.

Extended Study on the Use of Vocal Tract Variables to Quantify Neuromotor Coordination in Depression

TLDR
Changes in speech production that occur as a result of psychomotor slowing, a key feature of Major Depressive Disorder, are used to non-invasively diagnose MDD by using more subjects, taking into account more eigenvalue features and incorporating TVs related to place of articulation and the glottal source.

Vocal and Facial Biomarkers of Depression based on Motor Incoordination and Timing

TLDR
This work derives novel multi-scale correlation structure and timing feature sets from audio-based vocal features and video-based facial action units from recordings provided by the 4th International Audio/Video Emotion Challenge (AVEC).

Facial expressiveness in patients with schizophrenia compared to depressed patients and nonpatient comparison subjects.

TLDR
The patients with schizophrenia and the patients with depression presented similar deficits in various expressive modalities: posed and spontaneous emotional expression, smiling, coverbal gestures, and verbal output.

Automated Facial Expressions Analysis in Schizophrenia: A Continuous Dynamic Approach

TLDR
By defining dynamic and intensity AUs activation characteristic features, this work found evidence for blunted affect and reduced positive emotional expressions in patients, and designed learning algorithms which achieved up to 85 % correct schizophrenia classification rate, and significant correlation with negative symptoms severity.

Psychomotor retardation in depression: Biological underpinnings, measurement, and treatment

Social risk and depression: Evidence from manual and automatic facial expression analysis

TLDR
The finding that automatic facial expression analysis was both consistent with manual coding and produced the same pattern of depression effects suggests that automatic Facial expression analysis may be ready for use in behavioral and clinical science.

Language in Schizophrenia Part 1: An Introduction

  • G. Kuperberg
  • Psychology, Medicine
    Lang. Linguistics Compass
  • 2010
TLDR
Clinical characterizations of language output and the phenomenon of positive thought disorder are reviewed and evidence for the predominant theory of language dysfunction in schizophrenia: that it arises from abnormalities in semantic memory and/or working memory and executive function is given.

Cognitive remediation: a promising tool for the treatment of schizophrenia

TLDR
The present paper reviews the state of the art in cognitive remediation and demonstrates the effectiveness of board games in improving cognitive functioning, which seems to be a highly promising therapeutic avenue owing to its ease of use.

Negative v positive schizophrenia. Definition and validation.

TLDR
Criteria for dividing the schizophrenic syndrome into three subtypes was developed: positive, negative, and mixed schizophrenia, and significant differences were noted using external validators such as premorbid adjustment, indices of cognitive dysfunction, ventricular brain ratio, and course in hospital.

Facial Action Coding System

TLDR
An overview of FACS and the Action Units is provided, its reliability as a measure, and how it has been applied in some key areas of psychological research are provided.
