RELATIONSHIP OF VERBAL IQ WITH PERFORMANCE IQ AND FULL SCALE IQ ALONG WITH ANATOMICAL CHARACTERISTICS

Abstract

The connection between the complete brain size and general mental ability (GMA) was acknowledged universally. Connection between the performance intelligence quotient (PIQ) score and anatomical characteristics such as complete brain size, height, gender and weight are also narrated in many research papers. Very little study has been compiled to derive the relationship of verbal IQ (VIQ) with PIQ, full scale IQ (FSIQ) and anatomical characteristics. The current research report aims to develop the relationship of VIQ with the above mentioned variables. It is identified herein that VIQ is unequal variance random variable, and its mean is positively connected with FSIQ (P<0.0001), PIQ (P=0.1903), height (P= 0.0002), brain size (P=0.0181) and gender (P=0.0002), while it is negatively interrelated with the joint interaction effects of PIQ and height (PIQ*Height) (P<0.0001) and FSIQ*Gender (P<0.0001). Variance of VIQ is negatively interrelated with gender (P=0.0017), brain size (P=0.0040), height (P=0.0970), FSIQ*Gender (P=0.0032), while it is positively interrelated with PIQ (P=0.0321), Gender* Height (P=0.0322) and Gender*Brain size (P=0.0441). It is concluded herein that VIQ is higher for females with higher FSIQ, PIQ, larger brain size, longer height, and lower interaction effects of FSIQ*Gender and PIQ*Height.
