effect of in order to test the memory state in patients with non-insulin dependent diabetes mellitus (niddm) after glycemic control, one-hundred patients referring to isfahan endocrine and metabolism research center were simply randomized. they were compared in point of memory state with one hundred cases as the control group. the wechsler memory scale test was utilized to evaluate the memory s...

objective: working memory is the ability of maintaining and manipulating the required information for operating generalization in future. the aim of the present research is to investigate the effectiveness of neurofeedback therapy on the working memory in children with adhd.  methods: 24 children with adhd who had the required standards to participate in the study were selected by accessible sa...

an ideal orthodontic force system should exert continuous light force. thus, many efforts have been made to improve the memory characteristics of elastomeric chains. the aim of this study was to compare elastomeric chains (ecs) claimed by their manufacturers to offer high memory with traditional ones according to their force-extension diagrams.in this in-vitro study, ecs were divided into six g...

  Numerous studies conducted in laboratory animals and humans indicate that angiotensin converting enzyme inhibitors reinforce memory and learning. In this paper we study the effect of injection of enalapril into the cerebral ventricles on spatial memory of white mice in the double- y maze, following the induction of an Alzheimer- like amnestic model with scopolamine. To estimate the duration o...

visual memory is an important cognitive ability, which has been studied in individuals with autism spectrum disorders (asds). in such studies meaningful shapes were used more frequently. since meaningless shapes provide a better assessment of short term visual memory, in this study we used them to evaluate visual memory in children and adolescents with asds compared to the normal group.four vis...

The limited capacity of visual working memory (VWM) can be maximized by combining multiple features into a single representation through grouping principles such as connection, proximity, and similarity. In this study, we sought to understand how VWM organizes information by investigating how connection and similarity cues are used either alone or in the presence of another grouping cue. Furthe...

In "hybrid search" tasks, such as finding items on a grocery list, one must search the scene for targets while also searching the list in memory. How is the representation of a visual item compared with the representations of items in the memory set? Predominant theories would propose a role for visual working memory (VWM) either as the site of the comparison or as a conduit between visual and ...

Working memory (WM), an important posit in cognitive science, allows one to temporarily store and manipulate information in the service of ongoing tasks. WM has been traditionally classified as an explicit memory system-that is, as operating on and maintaining only consciously perceived information. Recently, however, several studies have questioned this assumption, purporting to provide eviden...

Although many of our perceptual biases stem from long-term, repeated exposure, current theories of visual search assume a central role for visual working memory (VWM) in guiding attention to target information. Crucially, whether a VWM representation guides attention depends on the relative priority that the memory has within VWM. Here, in a combined visual search/VWM task, we used attentional ...
