Sex differences on the Attention Test (AC), the Raven's Standard Progressive Matrices (SPM), and the Brazilian Cognitive Battery (BPR5), were investigated using four large samples (total N=6780), residing in the states of Minas Gerais and Sao Paulo. The majority of samples used, which were obtained from educational settings, could be considered a…

This study investigated the extent to which learning approaches can be accounted for by personal factors (i.e., demographics, ability, and personality). The participants were 443 students in a university in mainland China. The Revised Two-factor Study Process Questionnaire, the NEO Five-Factor Inventory-3, and the short form of Raven's Advanced…

The general factor of mental ability ("g") may reflect general biological fitness. If so, "g"-loaded measures such as Raven's progressive matrices should be related to morphological measures of fitness such as fluctuating asymmetry (FA: left-right asymmetry of a set of typically left-right symmetrical body traits such as finger…

The present study explored whether first and second order cognitive holding power perceived by children in mathematical classrooms, fluid intelligence, and mathematical achievement predicted their performance on standard problems, and especially realistic problems. A sample of 119 Chinese 4-6th graders were administered the word problem test, the…

This paper examines possible improvement to problem solving skills as a function of playing the video game "Portal 2." Stealth assessment is used in the game to evaluate students' problem solving abilities--specifically basic and flexible rule application. The stealth assessment measures will be validated against commonly accepted…

The article reports the results of three studies designed to extend the psychometric analyses of cultural intelligence (CQ) and to examine its utility in the prediction of cross-cultural adaptation. The first study supported the proposed four-factor (Cognitive, Meta-cognitive, Motivational, and Behavioral) structure of CQ in a large sample of…

The relationship between educational age and chronological age and measures of information processing and intelligence was studied in a group of children of 7 to 14 years of age (N=268) in a rural area in the Ntcheu district (Malawi). There was a relatively weak relationship between chronological and educational age in this area, and the impact of…

Flynn has proposed a grand integrative theory, which he calls "scientific spectacles," to explain the phenomenon of rising IQ scores across multiple decades known as the Flynn effect (FE). In his theory, he purports that modern society has placed increasing value and emphasis on the application and education of scientific…

The current study aimed at investigating the effect of the Master Thinker program on developing critical thinking skills of 11th grade students in Bahrain. Specifically, this research attempts to examine the hypothesis: Teaching the Master Thinker program will be significantly effective in developing critical thinking and its skills (inference,…

The concept of general intelligence ("g") summarizes the well established finding that scores on separate cognitive tasks are positively correlated, indicating a trait common to many aspects of information processing. Inspection time is a well-established correlate of IQ, where those of a higher IQ can correctly identify a briefly…

College undergraduates learned word lists involving three-term contingencies (stimulus-response-outcome). Learning rate was correlated approximately 0.5 with scores on Raven's Advanced Progressive Matrices (Raven) but did not correlate significantly with several tasks (inspection time, card-sorting, trail-making, PASAT) shown to be associated with…

Background: Children with cerebral palsy (CP) are at greater risk for a limited intellectual development than typically developing children. Little information is available which children with CP are most at risk. This study aimed to describe the development of non-verbal intellectual capacity of school-age children with CP and to examine the…

The purpose of this study was to identify possible differences between high- and low-risk sex offenders. The subjects included 285 sex offenders on probation. They were evaluated with the Static-99, Abel Assessment, Raven's, and MMPI-2. A criminal history review identified the number of prior offenses and the age/sex category in the index offense.…

This research study investigates effects of character education activities on the self-esteem of intellectually able and less able students in the lower elementary level in Kuwait. The participants were 39 students in grade three with an average age of eight years old. Students were first divided into two ability subgroups (intellectually able vs.…

The study investigated the effects of mediated learning experience (MLE) intervention on Remedial school learners' cognitive functioning as measured by the Ravens Coloured Progressive Matrices (RCPM). The sample comprised 67 participants (males = 35; females = 32; mean age = 11.8) from Grade 4 through to Grade 7. Participants were given the RCPM…
