It has become fashionable to equate constructs of working memory (WM) and general intelligence (g). Few investigations have provided direct evidence that WM and g measures yield similar ordering of individuals. Correlational investigations have yielded mixed results. The authors assess the construct space for WM and g and demonstrate that WM shares substantial variance with perceptual speed (PS...

We study the results of a descriptive and exploratory study, with the intent to understand the results of a 21 male schizophrenic patients interned in a Portuguese Mental Health Care Centre, evaluated with neuropsychological test. We tried also to link these tests with variables such as schooling, family contact or lengh of internment. The assessment instruments were: Digits Series and Vocabula...

The n-back task requires participants to decide whether each stimulus in a sequence matches the one that appeared n items ago. Although n-back has become a standard “executive” working memory (WM) measure in cognitive neuroscience, it has been subjected to few behavioral tests of construct validity. A combined experimental–correlational study tested the attention-control demands of verbal 2and ...

ôbjective: ëmotional intelligence (ëï) is a set of competencies that enable us to engage in sophisticated information processing of emotions and emotion-relevant stimuli and to use this information as a guide for thinking and behavior. prefrontal cortexes (pfç) of brain and related regions have an important role in emotion and emotional regulation. âccordingly, we conducted a study to investiga...

Objectives: The aim of the present study was to determine the effectiveness of attention training on the math performance of elementary school students with intellectual disability. Methods: The present research was a quasi-experimental study by pre-test, post-test design with the control group. The study population comprised students with intellectual disability aged 10-12 years. Subjects wer...

Traditional approaches to non-monotonic reasoning fail to satisfy a number of plausible axioms for belief revision and suffer from conceptual difficulties as well. Recent work on ranked preferential models (RPMs) promises to overcome some of these difficulties. Here we show that RPMs are not adequate to handle iterated belief change. Specifically, we show that RPMs do not always allow for the r...

BACKGROUND The purpose of the present study was to introduce a new device specifically designed to evaluate the cutting efficiency of mechanically driven endodontic instruments. MATERIAL AND METHODS Twenty new Reciproc R25 (VDW, Munich, Germany) files were used to be investigated in the new device developed to test the cutting ability of endodontic instruments. The device consists of a main f...

Objective: The study assessed the effect of a single session of repetitive peripheral magnetic stimulation (rpMS) combined with manual stretch on wrist and finger flexor muscle spasticity. Methods: Forty chronic patients after CNS lesion with a severe wrist and finger flexor spasticity with a Modified Ashworth Score (MAS, 0-5) of either 2, 3 or 4 participated and formed two groups. A single ses...

Introduction: Attention Deficit Hyeperactivity Disorder (ADHD) is a relatively prevalent disorder in children and is associated with some other disorders including depression. This problem also affects the emotional characteristics and intelligence quotient. The aim of this study was to examine the relationship of Emotional Characteristics (EC) and depression with Intelligence Quotient (IQ) in ...
