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.

Feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. Simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of Local Binary Pattern features. In this paper, we investigate the use of local binary patterns for percep...

OBJECTIVES The main purpose of this study was to culturally adapt the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) to Turkish and to evaluate its internal consistency, validity, and reliability. MATERIALS AND METHODS The Turkish version of CAPE-V was developed, and with the use of a prospective case-control design, the voice recordings of 130 participants were collected accordin...

OBJECTIVE Individuals are able to recognize common objects even when portions of them are obscured from view, reflecting the operation of neural perceptual closure processes. This study evaluates the integrity of object recognition and perceptual closure as a function of sensory and cognitive manipulations. METHOD Object recognition was examined in 26 subjects with schizophrenia and 23 nonpsy...

Humans perform saccadic eye movements two to three times per second. When doing so, the nervous system strongly suppresses sensory feedback for extended periods of time in comparison to movement time. Why does the brain discard so much visual information? Here we suggest that perceptual suppression may arise from efficient sensorimotor computations, assuming that perception and control are fund...

The present study was designed to assess the effects of the Transcendental Meditation (TM) program on strength of the nervous system, perceptual reactance, reaction time, and auditory threshold. Three reaction time indices of strength of the nervous system were utilized: 1) Nebylitsyn's index, 2) the slope index, and 3) the low level stimulation index. Absolute auditory threshold was the fourth...
