The purpose of this study was to investigate the relationship between goal orientation (Learning, Performance approach and Performance avoidance) and audit judgment with the mediator role of self-efficacy. The goal orientation is a personality trait that can be effective in performing tasks. The study is a pre-survey type-applied study. Also, a questionnaire was used to survey the subjects and ...

Previous studies have shown that autoimmune mice perform very poorly on active avoidance learning tasks. In the current studies, mice with lupus-like systemic autoimmunity were able to learn active, as well as passive, avoidance protocols with shock as reinforcement. Therefore, the behavioral deficits seen in active avoidance tasks are not a consequence of the use of electric shock. Rather, the...

Several studies suggest an opponent functional relationship between the lateral habenula (LHb) and the ventral tegmental area (VTA). Previous work has linked LHb activation to the inhibition of dopaminergic neurons during loss of reward, as well as to deficits in escape and avoidance learning. We hypothesized that a dopamine signal might underlie the negative reinforcement of avoidance response...

introduction: the role of serotonergic fibers in avoidance learning is controversial. involvement of the dorsal raphe nucleus (drn), the main source of hippocampal projecting serotonergic fibers in acquisition, consolidation and retrieval of passive avoidance (pa) learning, was investigated by functional suppression of this area. materials and methods: drn functional inactivation was done by li...

background: different stressors induce learning and memory impairment and physical activity influence learning and memory enhancement. in this research, we investigated the effect of synchronized running activity with stress on acquisition and retention time of passive avoidance test. methods: male wistar rats were randomly divided into five groups as follows: control (co), sham (sh), exercise ...

morphine’s effects on learning and memory processes are well known to depend on synaptic plasticity in the hippocampus. whereas the role of the hippocampus in morphine-induced amnesia and state-dependent learning is established, the biochemical and molecular mechanisms underlying these processes are poorly understood. the present study intended to investigate whether administration of morphine ...
