The relationship between the Rorschach Prognostic Rating Scale (RPRS) and the Wechsler Adult Intelligence Scale (WAIS) was investigated to identify the factors, intelligence and others, which contribute to the RPRS. Correlation between the RPRS total and WAIS FSIQ showed that approximately 43% of the variance in the RPRS total can be accounted for by the variance in the FSIQ. Verbal IQ is not s...

Twenty-four studies utilizing the Wechsler Adult Intelligence Scale (WAIS) Digit Span subtest--either the Reliable Digit Span (RDS) or Age-Corrected Scaled Score (DS-ACSS) variant--for malingering detection were meta-analytically reviewed to evaluate their effectiveness in detecting malingered neurocognitive dysfunction. RDS and DS-ACSS effectively discriminated between honest responders and di...

Dimensional structures underlying the Wechsler Memory Scale-Fourth Edition (WMS-IV) and Wechsler Memory Scale-Third Edition (WMS-III) were compared to determine whether the revised measure has a more coherent and clinically relevant factor structure. Principal component analyses were conducted in normative samples reported in the respective technical manuals. Empirically supported procedures gu...

As one of the psychological instruments that successfully provides an overview level intelligence children, Wechsler Intelligence Scale For Children (WISC) test needs to be evaluated its validity with psychometric procedures. The consists 10 subtests in which each subtest has many diverse items. This study included 315 kindergarten students age range 5-6 years. data obtained from it is then ana...

The Flynn effect has been widely researched in Western and European nations, while it has been comparatively understudied in Asian countries. This study examines possible Flynn effects in China from 1985-86 and to 2011-12. Results are reported for an IQ increase among 12 year olds on the Full Scale IQ WISC-R (Wechsler Intelligence Scale for Children- Revised) of 6.19 IQ points, a gain on the Pe...

We examine updated Wechsler IQ data in 7-year old twins from the Louisville Twin Study for evidence of an interaction between the heritability of IQ and socioeconomic status. Data records that had never been entered were recovered, allowing us to increase previously reported sample sizes by more than 20%. Twin families were assigned socioeconomic status scores using a Hollingshead index based o...
