How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Some researchers suggest that deficits in attention and working memory influence the development of dyslexia, whereas others propose that these deficits are more likely due to reduced global processing speed. The current study aimed to investigate behavioral performance in children with dyslexia compared to typically developing controls on two task...
Previous work suggests that threat-related stimuli are stored to a greater degree in working memory compared to neutral stimuli. However, most of this research has focused on stimuli with physically salient threat attributes (e.g., angry faces), failing to account for how a “neutral” stimulus that has acquired threat-related associations through di...
Background and objectives
Few studies have evaluated the link between working memory (WM) and post-traumatic stress disorder (PTSD). Further, it is unknown whether this relationship is accounted for by other relevant variables including negative affect, emotional dysregulation, or general non-WM-related cognitive control deficits, which are associa...
Background: Trait anxiety is characterized by impaired gating of threat from working memory (WM), allowing unnecessary
maintenance of anxious cognitions. Improving filtering efficiency of threatening information through computerized WM
training might reduce intrusive, worrisome thoughts.
Methods: We randomized high-trait anxious individuals to 9 se...
Evidence suggests that threatening stimuli induce attentional biases compared to neutral stimuli, leading to subsequent storage in working memory. The current study examined how threatening versus neutral word distracters influence attention, and how this affects the unnecessary storage of these task-irrelevant stimuli in working memory. We measure...
Working memory (WM) is a core cognitive ability important for everyday functioning. A burgeoning area of research suggests that WM can be improved via working memory training (WMT) paradigms. Additionally, recent research has shown that WM may be enhanced through noninvasive neuromodulation such as transcranial direct current stimulation (tDCS). In...
Current theories propose that anxiety adversely impacts working memory (WM) by restricting WM capacity and interfering with efficient filtering of task‐irrelevant information. The current study investigated the effect of shock‐induced state anxiety on WM capacity and the ability to filter task‐irrelevant neutral stimuli. We measured the contralater...
Reward-related stimuli capture attention, even when they are task irrelevant. A consequence of attentional prioritization of reward-related stimuli is that they may also have preferential access to working memory like other forms of emotional information. However, whether reward-related distracters leak into working memory remains unknown. Here, us...
Many individuals with obsessive-compulsive disorder report that obsessional thoughts and compulsive behaviors are often motivated by “not just right” experiences (NJREs). Individuals who experience NJREs often report symptoms related to symmetry, order, and arrangement (SOA). The current study sought to develop a brief picture-based measure of NJRE...
Dyslexia is a brain-based reading disability characterized by deficit in phonological processing. In this paper the effect of computer working memory (WM) training on EEG signals of 15 dyslexic children has been investigated. For this purpose, three sets of EEG were recorded from the subjects before and after the computer treatment. Each set of EEG...
The aim of the present study was to evaluate the psychometric properties of an expert system computer program to help children to be diagnosed with autistic disorder. Developing expert systems requires a knowledge base and inference machine. To provide the knowledge base of expert system, items of the history of autism-related diagnosis were collec...
Anger has always been recognized as a natural emotion of human being, however, inappropriate expression of anger has negative consequences such as destructive effects on the living quality of the family, interpersonal behaviour and mental states of the individuals. For this reason, conducting research in the area of anger management is considered t...
The objective of the present study is to evaluate the workshops for teaching new parenting styles based on problem solving approach. One of the advantages of these workshops is the fact that parents along with their children participate in various activities and are encouraged to ponder upon issues. Each session consists of a lesson plan presenting...
Introduction:The present study was conducted with the aim of surveying the effectiveness of Donald Meichenbaum cognitive behaviour modification therapy .Method:The method of this study is pure experimental research with pre test-post test with control group .The society of study , contains all high school students in the Tehran. For performing this...
The ability to solve problems is one of the crucial skills in our life. Along with brisk changes in new societies, social demands and standards have been changed, and human being, now is facing new and more complicated challenges. Resolving many of these new problems require a higher level of thinking abilities. Since many individuals possess poten...
