Overview of the most important similarities and differences between schizophrenia and ASD, differentiated according to the three interconnected dimensions of self, intersubjectivity and relation to the life-world.

	Schizophrenia	Autism Spectrum Disorder
Self-Constitution	- disorder of the minimal self/impaired basic self-affection	- intact basic self-affection
	- interpersonal self is reduced - deviations of the interpersonal self are fundamental - there are indications of a narrative self-disorder, but they are not considered central
Intersubjectivity	Both can be characterized as:  1. a reduced participation in the intersubjectively constituted lifeworld/common sense  2. a diminished interbodily resonance Social understanding in general and the implicit understanding of social cues in particular appear to be more severely reduced in ASD than in schizophrenia.
Relation to the life-world: to lived space: to time: delusional experience:	1. patients can lose the sense of a subjective center 2. impairment of bodily/operative intentionality 3. no preference on non-social objects ⇒ relationship with the life-world is fragmented	1. Patients keep their subjective center 2. no impairment of operative intentionality 3. increased fixation on non-social objects ⇒ relationship with the life-world is stable
	- objects themselves can be perceived as altered e.g.: micropsia, dysmegalopsia e.g.: sensory hyper- or hyposensitivity
	- fragmentation of the intentional arc/disturbed retentional-protentional structure - no stereotypes	- intact retentional-protentional structure - implementation of stereotypes so that the present continues unchanged; the flow of time can be interrupted by external changes
	- difficulties in perspective-taking
	- subjectivized perception or “self-centrality” - externalizing attribution bias/minimal self-disorder as influencing factors for delusion ⇒ resulting in persistent delusional experience	- no subjectivized perception - no externalizing attribution bias/minimal self-disorder ⇒ resulting in short-lasting delusional experience
