Abstract Naïve realists hold that the phenomenology of veridical perceptual experience is in part constituted by environmental objects subject perceiving. Although naïve realism well-motivated considering cognitive and epistemic roles experience, it considered difficult to explain hallucinatory imaginative experiences. This paper provides three arguments address these explanatory problems syste...

AIMS This study aimed to establish the contribution of hallucination proneness, anxiety, suggestibility, and fantasy proneness to psychotic-like experiences (PLEs) reported during brief sensory deprivation. METHOD Twenty-four high and 22 low hallucination-prone participants reported on PLEs occurring during brief sensory deprivation and at baseline. State/trait anxiety, suggestibility, and fa...

Introduction: Many conditions can mimic psychiatric symptoms. Amongst them, intracranial mass and space occupying lesions have a significant importance. Aggression and hallucination are seen in association with a basal frontal lesion, and may mimic psychotic syndromes. Case Presentation: A 37-year-old man with no previous mental illness presented with a month history of headache, blurred vision...

Disjunctivism about perceptual appearances, as I conceive of it, is a theory which seeks to preserve a naïve realist conception of veridical perception in the light of the challenge from the argument from hallucination. The naïve realist claims that some sensory experiences are relations to mind-independent objects. That is to say, taking experiences to be episodes or events, the naïve realist ...

Disjunctivism about perception is a view about the relation between veridical experiences and hallucinations. Suppose that I see a green cube, and my experience is veridical—no illusion or hallucination is involved.1 The veridical experience, according to disjunctivists, includes as constituents the bit of the world that is perceived and the perceptual relation that the subject bears to it, and...

BACKGROUND The pathophysiology of auditory verbal hallucinations remains poorly understood. AIMS To characterise the time course of regional brain activity leading to auditory verbal hallucinations. METHOD During functional magnetic resonance imaging, 11 patients with schizophrenia or schizoaffective disorder signalled auditory verbal hallucination events by pressing a button. To contro...

Schizophrenic patients suffer from hallucination which its causality is not yet fully understood. This paper attempts to approach this mystery from the perspective of quantum mechanical theories. A novel approach has been adopted to demonstrate the hallucination as a time evolution of percepts basis states in the Hilbertian consciousness which are desynchronised from the time in real world. The...
