Early schizophrenia alters perception, making the environment seem mysterious and objects overly significant. This study explores how disturbed intentional and embodied perception contribute to delusional experiences in schizophrenia.

Area of Science:

  • Phenomenology
  • Psychiatry
  • Cognitive Science

Background:

  • Schizophrenia onset involves altered environmental and object perception.
  • Patients experience the world as stage-like and objects as overly significant, sometimes merging with the body.

Purpose of the Study:

  • To explain perceptual alterations in early schizophrenia using phenomenological concepts.
  • To analyze the roles of intentional (gnostic) and embodied (pathic) perception in these changes.

Main Methods:

  • Utilizes Husserl's concept of intentional perception.
  • Employs Merleau-Ponty's concept of embodied perception.

Main Results:

  • Schizophrenic perception involves a 'paralysis of intentionality,' disrupting sense-making.

  • The 'pathic' component of perception becomes disinhibited, leading to idiosyncratic meanings.
  • Disturbed intentional perception results in heightened physiognomic and expressive qualities.

    • Conclusions:

    • Altered perception in schizophrenia stems from a breakdown in the interplay between intentional and embodied perception.
    • This breakdown leads to a loss of intersubjective reality and the emergence of delusional perception.
