Objective: This study aimed at determining personality traits, cognitive strategies of emotion regulation, attachment styles, and brain-behavioral systems as predictors of impulsiveness, active and non-active addiction potential among university students. Method: All the male students of Azad University of Ahwaz in the academic year 2013-2014 constituted the statistical population of this study...
J. A. Gray's (1975) theory distinguishes between two motivational systems, which he refers to as the behavioral activation system (BAS) and the behavioral inhibition system (BIS). D. C. Fowles (1980) has shown that heart rate responses reflect activity of the BAS, and electrodermal responses reflect activity of the BIS. Both BAS and BIS are reliably activated during in-vivo exposure to fearful ...
To analyze the involvement of different brain regions in behavioral inhibition and impulsiveness, differences in activation were investigated in fMRI data from a response inhibition task, the stop-signal task, in 1709 participants. First, areas activated more in stop-success (SS) than stop-failure (SF) included the lateral orbitofrontal cortex (OFC) extending into the inferior frontal gyrus (ve...
Mutual inhibition among behavioral command systems frequently has been suggested as a possible mechanism for switching between incompatible behaviors. Several neural circuits in crayfish that mediate incompatible behaviors have been found to interact through inhibition; this accounts for increased stimulus threshold of one behavior (e.g., escape tailflip) during performance of others (eating, w...
Objectives This study aimed to predict the intensity of pain based on the amount of alexithymia in patients with chronic pain, and in this relationship, the behavioral inhibition system has a mediating role. Methods The present study has a correlational design and carried out with a structural equation modeling approach. The statistical population comprised all 20-60 years old patients with ch...
Gray's Reinforcement Sensitivity Theory postulates that the behavioral inhibition system (BIS) is responsible for regulating anxiety and fear in response to external stimuli, while activation (BAS) processing positive cues such as rewards. Dickman's model distinguishes dysfunctional impulsivity (DI), characterized by non-reflective decision-making, from functional (FI), which reflects propensit...
Background: Previous studies have shown that impulsive or uncontrolled behaviors in addicts to obtain the drug and drug abuse may be due to overcome one of the brain/behavioral systems. In this study we sought to answer the question whether the overcoming can be associated with relapsing or not? Materials and methods: The method of research was causative-comparative. To achieve our aim, we cate...
BACKGROUND Williams syndrome (WS) has provided researchers with an exciting opportunity to understand the complex interplay among genes, neurobiological and cognitive functions. However, despite a well-characterized cognitive and behavioral phenotype, little attention has been paid to the marked deficits in social and behavioral inhibition. Here we explore the neural systems that mediate respon...
The purpose of this study was to investigate the relationship between brain systems behavior and impulsivity, with high-risk sexual behavior. The review was detailed co-relational research. The population consists of all undergraduates of universities in Mashhad were enrolled in the academic year 1396. A total of 100 students male volunteered and were chosen using the sampling method. Data was ...
