The roughening behavior of a one-dimensional interface fluctuating under quenched disorder growth is examined while keeping an anchored boundary. The latter introduces detailed balance conditions which allows for a simple but thorough analysis of equilibrium aspects at both macroscopic and microscopic scales. It is found that the interface roughens linearly with the substrate size only in the v...

We show some connections between psychodynamic view of the psychic system, in which dissociation is a basic element of the system dynamics, and neural level of the brain. The dissociation represents competition among complexes that correspond to ideas or mental representations in parallel distributed processing (PDP). In PDP models dissociation represents low synaptic strength among mental repr...

Research has shown that attempts to suppress a thought can cause an increase in the frequency of the thought. These paradoxical effects of thought suppression play a key role in cognitive-behavioral models of several emotional disorders. Laboratory studies of this phenomenon, however, have yielded mixed results; and narrative summaries of the literature have not been able to draw firm conclusio...

This study investigated the differences between the Standard and Short forms of MicroCog by comparing Domain scores for a clinical sample of 351 substance abusers which gave a significant difference between scores on the Spatial Processing Domain. Implications for research and clinical use are discussed.

(Central) auditory processing disorder (C)APD has been defined as a neural deficit in the processing of auditory stimuli and its underlying brain activity (Chermak & Musiek, 2007), although there is no consensus in the field surrounding its definition, diagnosis, assessment or intervention (DeBonis & Moncrieff, 2008; McArthur, 2009). Auditory training is one form of intervention often used to t...

Representational neglect, which is characterized by the failure to report left-sided details of a mental image from memory, can occur after a right hemisphere lesion. In this study, we set out to verify the hypothesis that two distinct forms of representational neglect exist, one involving object representation and the other environmental representation. As representational neglect is considere...

Numerous psychophysical studies have described perceptual learning as long-lasting improvements in perceptual discrimination and detection capabilities following practice. Where and how long-term plastic changes occur in the brain is central to understanding the neural basis of perceptual learning. Here, neurophysiological research using non-human primates is reviewed to address the neural mech...

Previous studies have demonstrated a left perceptual bias while looking at faces, due to the fact that observers mainly use information from the left side of a face (from the observer's point of view) to perform a judgment task. Such a bias is consistent with the right hemisphere dominance for face processing and has sometimes been linked to a left gaze bias, i.e. more and/or longer fixations o...


 Background: Mental disorders are psychological or behavioral that occur in a person, generally associated with affective, behavioral, cognitive and perceptual disorders. Schizophrenic patients have symptoms including thought process disorders, affective emotional volitional psychomotor secondary the form of delusions hallucinations.
