iran’s economy has experienced an average inflation rate of 18.77 percent during the period of 1979-2010. many economists believe that the budget deficits are one of the main determinants of the chronic and relatively high inflation. this paper investigates the relationship between budget deficits and inflation. dynamics of iran’s monetary sector, based on the three cointegration relations i.e....

Awareness of deficits after brain injury represents a significant clinical and theoretical challenge, but relatively little is known about the neuroanatomical correlates of specific types of deficit awareness. We examined the awareness correlates of left versus right prefrontal cortex lesions in comparison to left and right posterior lesions including two types of awareness measures--metacognit...

In addition to physical disability, multiple sclerosis (MS) is increasingly recognized for its association with neuropsychological (NP) impairment, including cognitive deficits and disorders of mood and affect. NP impairment can occur as early as the first demyelinating episode. Often insidious in nature, NP impairment has a significant impact on a wide range of quality-of-life measures includi...

OBJECTIVE Fronto-striatal dysfunction has been discussed as underlying symptoms of Tourette syndrome (TS) with co-morbid Obsessive Compulsive Disorder (OCD). This suggests possible impairments of executive functions in this disorder, which were therefore targeted in the present study. METHODS A comprehensive series of neuropsychological tests examining attention, memory and executive function...

To explore the idea that deficits in source monitoring may underlie positive symptoms of schizophrenia, the current study compared schizophrenic patients' performance (n=15) on an internal source-monitoring task with that of normal controls (n=15). On the basis of a source-monitoring task in which participants had to recall whether they had verbalized answers or merely thought about these answe...

This research examined the development of the ability to monitor memory strength and memory absence at retrieval. In two experiments, 7-year-olds, 10-year-olds, and adults enacted and imagined enacting a series of bizarre and common actions. Two weeks later, they completed a memory test in which they were asked to determine whether each action had been enacted, had been imagined, or was novel a...

Greater extent of resection (EOR) of low-grade gliomas is associated with improved survival. Proximity to eloquent cortical regions often limits resectability and elevates the risk of surgery-related deficits. Therefore, functional localization of eloquent cortex or subcortical fiber tracts can enhance the EOR and functional outcome. Imaging techniques such as functional MRI and diffusion tenso...

The current study aimed to address error monitoring impairments in dementia using an intervention for execution deficits. Thirty-eight participants completed the Naturalistic Action Test (NAT) under two conditions: Standard and User-Centered. The Standard NAT followed the manual procedures; in the User-Centered NAT, objects were arranged sequentially, and distractor items were separated from ta...
