prevention of disabilities and handicaps, including mental relardation and low intelligence, is one of the important aims of health programmes. therefore, understanding the causes of such disabilities could reduce their incidence. a cause of low iq and mental retardation is prematurity and this could be the result of low age of mothers at the time of pregnancy. this study investigates the relat...

Objective(s): A novel IQ-SPECTTM method has become widely used in clinical studies. The present study compares the quality of myocardial perfusion images (MPI) acquired using the IQ-SPECTTM (IQ-mode),conventional (180° apart: C-mode) and L-mode (90° apart: L-mode) systems. We assessed spatial resolution, image reproducibility and quantifiability using various physical phantoms. Materials and Me...

Introduction: Children with cochlear implants (CIs) may experience few opportunities for positive musical experiences, and musical perception is therefore often not sufficiently developed. This paper investigates and discusses the relationship between intelligence quotient (IQ) and musical ability in children with CIs compared with children with normal hearing.                                  ...

Background: Congenital hypothyroidism (CH) is one of the preventable causes of intellectual disability. The aim of this study was to compare intelligence quotient (IQ) in early treated children with CH and healthy children. Materials and Methods: This cohort study was conducted on 78 early tre...

raven progressive matrices (rpms) and wechsler intelligence scale for children (wsic-r) are two common general intelligence measuring scales used in iranian high schools. in this paper the relationships between g factor scales and students’ reading comprehension, grammar, and vocabulary was examined by correlation and regression analysis. standard tests of grammar and vocabulary and cambridge k...

One of the main components in information quality (IQ) assurance is an IQ measurement model design and operationalization. One cannot manage IQ without first being able to measure it meaningfully and establishing a causal connection between the source of IQ change, the IQ problem types, the types of activities affected, and their implications. A better understanding is needed of the roots of IQ...

INTRODUCTION Although cognitive impairments in adults with Noonan syndrome seem to be limited to a low-average intelligence and slower processing speed, studies in children with Noonan syndrome have demonstrated more extensive cognitive problems. These include deficits in language skills, memory, attention, and executive functioning. This longitudinal study is the first to investigate intellect...
