OBJECTIVE The aim of this study was to examine the concurrent validity of a newly developed computerized memory diagnostic system (MDS) with the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet (CERAD-K). METHODS Subtests of the MDS and CERAD-K, including the auditory-verbal, visuo-spatial, and working memory tests, were administered to 43 adu...

To determine the mechanism of STM decline following brain damage, patients with left hemisphere damage and aphasia (LHD+), patients with left hemisphere damage without aphasia (LHD-), and persons with right hemisphere dysfunction (RHD) were examined. An auditory-verbal memory task, as well as a series of visual memory tasks, consisting of designs, objects and pictures, were used. Patients with ...

INTRODUCTION Dissociation is a disruption in the integrated functions of consciousness, memory, identity, and perception. Dissociative symptoms include derealization/depersonalization, absorption, and amnesia. These experiences can cause a loss of control over mental processes, including memory and attention. In literature, there is a paucity of research concerning the relationships between dis...

We used a previously validated automated machine learning algorithm based on adaptive boosting to segment the hippocampi in baseline and 12-month follow-up 3D T1-weighted brain MRIs of 150 cognitively normal elderly (NC), 245 mild cognitive impairment (MCI) and 97 Dementia of the Alzheimer's type (DAT) ADNI subjects. Using the radial distance mapping technique, we examined the hippocampal corre...

Much interest has recently been directed toward the knowledge of collocations in the field of second language learning since they have been asserted to improve fluency. The current study was intended to examine the effect of verbal and visuospatial working memory spans on the processing of collocations using a Self-Pace Reading Task (SPRT) and relevant working memory tasks. To this end, partici...

There are two main common misconceptions: the first is that dyslexia’s chief characteristic is difficulty with reading. This is very often not the case. An adult with dyslexia may be slightly slow in reading but otherwise competent. The chief characteristics of dyslexia in adulthood are weaknesses in phonology, auditory short-term memory (working memory), and visual processing skills. These wea...

background: the purpose of the present study was to evaluate the psychometric properties (validity and reliability) of the persian version of the sustained auditory attention capacity test in children with attention deficit hyperactivity disorder. methods: the persian version of the sustained auditory attention capacity test was constructed to assess sustained auditory attention using the metho...
