In 1990, Thomas J. Bouchard, Jr. and colleagues published the widely cited 1990 “Minnesota Study of Twins Reared Apart” (MISTRA) Science IQ study. To arrive at conclusion that “IQ is strongly affected by genetic factors,” Bouchard omitted their control group reared-apart dizygotic twin (“DZA”) IQ-score correlations. Near-full-sample correlations after study’s 2000 endpoint show monozygotic (“MZ...

Article history: Received 26 January 2013 Accepted 22 February 2013 Available online 21 March 2013 Kagitcibasi and Biricik (2011) presented generational IQ gains for Turkey on the Goodenough Draw-a-Man test (Draw-a-Person). Following their results (their Table 1) the mean IQ gain from 1977 to 2010 (33 years) across three different population groups was 5.24 IQ (per decade dec = 1.59 IQ points)....

Although the intelligence quotient (IQ) is the most popular intelligence test in the world, little is known about the underlying biological mechanisms that lead to the differences in human. To improve our understanding of cognitive processes and identify potential biomarkers, we conducted a comprehensive investigation of 158 IQ-related genes selected from the literature. A genomic distribution ...

The present study compared children with Attention-Deficit Hyperactivity Disorder (ADHD) and controls on a selected set of clinical measures of executive function (EF). A total of 92 children (51 ADHD, 41 control), ages 6-16, completed measures chosen from a larger neuropsychological battery to illustrate diverse components of the EF construct (planning, inhibitory control, response preparation...

The IQGAP [IQ-motif-containing GAP (GTPase-activating protein)] family members are eukaryotic proteins that act at the interface between cellular signalling and the cytoskeleton. As such they collect numerous inputs from a variety of signalling pathways. A key binding partner is the calcium-sensing protein CaM (calmodulin). This protein binds mainly through a series of IQ-motifs which are locat...

the aim of this study was to examine the effect of a rhythmic motor program on the perceptual – motor abilities (pma) and the intelligence quotient (iq) of educable mentally retarded (emr) children. the sample consisted of 24 emr girls (mean age = 11.98+1.43 years and iq = 70.58+ 9.95). then, they were matched and assigned to two groups of intervention and control according to their iq and pma ...

Laser refractive surgery for myopia increases the eye's higher-order wavefront aberrations (HOA's). However, little is known about the impact of such optical degradation on post-operative image quality (IQ) of these eyes. This study determined the relation between HOA's and IQ parameters (peak IQ, dioptric focus that maximized IQ and depth of focus) derived from psychophysical (logMAR acuity) a...

Social media has become an integral part of people’s lives. People share their daily activities, experiences, interests, and opinions on social networking websites, opening the floodgates of information that can be analyzed by marketers as well as consumers. However, low barriers to publication and easy-to-use interactive interfaces have contributed to various information quality (IQ) problems ...
