Motivation and attention can have a profound influence on perception, learning and memory. Neuromodulatory systems, especially the noradrenergic (NE) system, co-vary with psychological states to modulate cortical arousal, influence sensory processing and promote synaptic plasticity. There is even some suggestion that the NE system might facilitate functional recovery after brain damage. Post-sy...

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...

Introduction: Studies related to investigating reasons of mental disorders emphasize on role of environmental factors in creation of the disorders. For this reason, in this paper, a research was conducted to investigate the relationship between BIS/BAS systems and emotional regulation difficulties with alexithymia. Methods: 200 undergraduate students of University of Tabriz in majors includi...
