Stochastic catastrophe analysis of switches in the perception of apparent motion.

The influence of adaptation and stochastic fluctuations on spontaneous perceptual changes for bistable stimuli.

Spontaneous perceptual change was studied by measuring the probabilities of the first two spontaneous pattern switches as a function of time following the onset of a bistable apparent quartet for which either horizontal or vertical motion is perceived. Contrary to the classical satiation hypothesis (Köhler & Wallach, 1944), differential time-dependent adaptation of the perceived compared with t...

Structural modeling of pain perception in people with chronic pain syndrome based on behavioral inhibition system: mediated by pain catastrophe and perceived social support

Abstract Introduction: Chronic pain, especially skeletal muscle pain, is very common and can affect the quality of life and health of the patient and families; Therefore, the present study was conducted to investigate the relationship between behavioral inhibition system and pain perception by mediating role of pain catastrophe and perceived social support in people with chronic pain syndrome....

The Generation of Earthquake PGA Using Stochastic Finite Fault Method in Alborz Region

Time-history analysis is defined as a kind of dynamic analysis increasingly used in design of structures and evaluation of existing ones. One of the important issues in the Time-history analysis is selecting earthquake records. In this case, seismic design provisions states that time histories shall have similar source mechanisms, geological and seismological features with region under study. A...

Standardization and Evaluation of Psychometric Properties of the self-perceived burden Questionnaire (SPBQ) in chronic pain patients

Background and Objectives: Self-perception burden is one of the most important aspects of chronic pain. the present study is to determine the psychometric properties of the Self-perception burden Scale a sample of Iranian chronic pain patients. Methods: In this study, 324 male and female chronic pain patients in Tehran were examined by the available sampling method. For convergent validity, the...
