Can interpersonal hypersensitivity under subconscious condition explain paranoid symptom in schizophrenia?

Abstract

These findings suggest that schizophrenia patients exhibit attentional bias to interpersonal interaction behaviors at both conscious and subliminal levels but toward opposite directions. Our findings shed light on the subconscious deficits under the paranoid symptom in schizophrenia.

Continuous flash suppression operates in local spatial zones: Effects of mask size and contrast

“…Since surround suppression could operate in interocular, monocular and binocular presentations (Chubb, et al, 1989;Paffen et al, 2004;Paffen et al, 2005), our findings support a previous claim by , who posited that the use of large maskers and spatially similar targets facilitated the observation of temporal frequency selectivity in CFS. Moreover, the demonstration of surround suppression in CFS raises important implications for schizophrenia research, which has recently adopted the technique to examine the unconscious processing of eye gaze (Seymour, Rhodes, Stein & Langdon, 2016), affective faces (Kring, Siegel & Barrett, 2014) and interpersonal interactions (Zhu et al, 2015). As schizophrenic patients have been found to exhibit weaker surround suppression for stimuli defined by size and contrast, but not luminance and orientation (Tibber et al, 2013), it would be interesting to see if their performances on CFS tasks are related to their deficits in surround suppression.…”

“…This emotion dysregulation can also be observed in Disruptive Mood Dysregulation Disorder, Oppositional Defiant Disorder, the Severe Mood Dysregulation Disorder and the Sensory Processing Disorder. In schizophrenia, this extreme sensitivity to the environment can manifest itself through the extreme emotional intensity and variability experienced (Myin-Germeys et al, 2000), the higher levels of emotional reactivity to daily life stress (Myin-Germeys et al, 2001), the emotional overinvolvement (Leff, 1976) and interpersonal hypersensitivity (Zhu et al, 2017). In BD this extreme sensitivity can be understood as enhanced sensitivity to rewarding stimuli (Alloy & Nusslock, 2019) and an emotional reactivity to the environment that influences the different phases.…”

“…Cette dysrégulation des émotions peut également être observée dans le trouble de la régulation de l'humeur, le trouble oppositionnel avec provocation, le trouble sévère de l'humeur et le trouble du traitement sensoriel. Dans la schizophrénie, cette sensibilité extrême à l'environnement peut se manifester par une intensité et une variabilité émotionnelles extrêmes (Myin-Germeys et al, 2000), des niveaux plus élevés de réactivité émotionnelle au stress de la vie quotidienne (Myin-Germeys et al, 2001), une implication émotionnelle excessive (Leff, 1976) et une hypersensibilité interpersonnelle (Zhu et al, 2017). Dans le TB, cette sensibilité extrême peut être comprise comme une sensibilité accrue aux stimuli gratifiants (Alloy & Nusslock, 2019) et une réactivité émotionnelle à l'environnement qui influence les différentes phases.…”
