A review of emotion deficits in schizophrenia

Open access

Abstract

Emotion deficits in schizophrenia have been described since the time of Kraepelin. However, no comprehensive review of clinical emotion studies has ever been conducted. In this work, studies that used diagnostic criteria and were published in English were selected from an extensive PubMed search. Fifty-five studies on emotion expression repeatedly showed that individuals with schizophrenia (IWSs) display fewer overt expressions than nonpatient comparison subjects (NCSs) in verbal, facial, and acoustic channels. No clear differences were found between IWSs and depressed subjects. Sixty-nine studies examined emotion experience in schizophrenia. IWSs report higher anhedonia, and they tend to show more negative emotions in real-life event studies. In evocative studies, they report a similar degree of pleasantness and a similar or higher degree of unpleasantness. From 110 studies, it can be concluded that emotion recognition is impaired in schizophrenia in all channels. These deficits in social perception are correlated with neurocognitive deficits and some social skills. IWSs show dysfunction in the three domains of emotion expression, emotion experience, and emotion recognition, and these dysfunctions appear to be independent of each other across domains. These deficits in basic emotion processing may be linked to psychopathology and functional outcomes.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Because people with schizophrenia have varied emotion-processing difficulties, it is uncertain whether impaired imitation of emotional stimuli reflects imitation itself or other emotional processes.

    “Third, because patients display a variety of problems in processing of emotions, 46 it is unclear whether a deficit in voluntary or automatic imitation of emotional stimuli 11,12,47,48 would reflect a specific impairment in imitation, or other aspects of emotion processing”
  • Individuals with schizophrenia show diminished positive and negative emotions in response to emotional movie clips, food, and social exchange, even when taking medication.

    “Individuals with schizophrenia show diminished positive and negative emotions in response to emotional movie clips [387], food [388], and social exchange [389-391], even when taking medication [388].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
