aim and background: cognitivists have recently paid extensive attention to source monitoring deficit as an impairment in schizophrenic patients and is used in clarification of major symptoms including hallucination and delusion. therefore, the present study aimed to explore the effects of source monitoring ability in auditory hallucination. methods and materials: this causal-comparative study u...

BACKGROUND Hallucinations are a core diagnostic criterion for psychotic disorders and have been investigated with regard to its association with childhood trauma in first-episode psychosis samples. Research has largely focused on auditory hallucinations, while specific investigations of visual hallucinations in first-episode psychosis remain scarce. OBJECTIVES The aims of this study were to d...

BACKGROUND Charles Bonnet Syndrome (CBS) is widely considered a transient condition without adverse consequence, questioning the need for treatment. Yet, while this view may be true of the majority of people with CBS, it is recognised that some have negative experiences and outcomes. Here, we attempt to better understand negative outcome CBS and the factors that influence it. METHODS 4000 mem...

BACKGROUND Research has been studying the relationships between drug use and the risk of suffering psychopathological disorders. This study analyzed the relationships existing between this use and certain psychotic disorder risk variables: hallucination, schizotypy and cognitive fusion. METHOD Several screening questionnaires on drug use (CAGE), a questionnaire on "cognitive fusion" (TAFS), a...

OBJECTIVE This study aims to revise empirical studies that were used to evaluate the effectiveness of cognitive-behavioral group treatment programs in the treatment for schizophrenia and other psychotic disorders. METHOD Articles in English that were published between the years of 1980 and 2011 (july) have been searched in the: PsycINFO, PsycARTICLES and MEDLINE databases by using "(1) psycho...

BACKGROUND The Kii peninsula of Japan is one of the foci of amyotrophic lateral sclerosis and parkinsonism-dementia complex (ALS/PDC) in the world. The purpose of this study is to clarify the neuropsychological features of the patients with ALS/PDC of the Kii peninsula (Kii ALS/PDC). METHODS The medical interview was done on 13 patients with Kii ALS/PDC, 12 patients with Alzheimer's disease, ...

Due to the under-sparsity or over-sparsity, the widely used regularization methods, such as ridge regression and sparse representation, lead to poor hallucination performance in the presence of noise. In addition, the regularized penalty function fails to consider the locality constraint within the observed image and training images, thus reducing the accuracy and stability of optimal solution....

The content, modality, and perceptual attributes of hallucinations and other psychotic symptoms may be related to neural representation at a single cell and population level in the cerebral cortex. A brief survey of some principles and examples of cortical representation and organization will be presented together with evidence for a correspondence between the neurobiology of brain areas activa...

Face hallucination refers to inferring an High-Resolution (HR) face image from the input Low-Resolution (LR) one. It plays a vital role in LR face recognition by both manual and computer. The eigentransformation method based on Principal Component Analysis (PCA), which represents face image as a linear combination of the eigenfaces, has attracted considerable interests because of its simplicity...

Fig. 1. Group-mean percent-correct recognition of the target keywords for the health-control participants (top panel) and patient participants (middle panel) as a function of signal-to-masker ratio (SMR) along with the group-mean best-fitting psychometric functions under the no-priming condition (open triangles and dash curve), false-priming condition (open squares and dash curve), and true-pri...
