The Cattell-Horn-Carroll (CHC) or three-stratum model of intelligence envisions human intelligence as a hierarchy. General intelligence (g) is situated at the top, under which are a group of broad intelligences such as verbal, visuospatial processing, and quantitative knowledge that pertain to more specific areas of reasoning. Some broad…

Working memory capacity (WMC) and fluid intelligence (Gf) are highly correlated, but what accounts for this relationship remains elusive. Process-overlap theory (POT) proposes that the positive manifold is mainly caused by the overlap of domain-general executive processes which are involved in a battery of mental tests. Thus, executive processes…

Numerous recent studies seem to provide evidence for the general intellectual benefits of working memory training. In reviews of the training literature, Shipstead, Redick, and Engle (2010, 2012) argued that the field should treat recent results with a critical eye. Many published working memory training studies suffer from design limitations…

The aim of this study is to describe naive conceptions of creativity and offer some explanation for their variability. Two methods are used to analyze conceptions of creativity. The first one consists of analyzing adjectives that are associated by naive judges with the notion of creativity of an advertisement. The second one consists of predicting…

Many people believe that environmental factors promote giftedness and invest in many programs to adopt gifted students providing them with challenging activities. Intellectual giftedness is founded on fluid intelligence and extends to more specific abilities through the growth and inputs from the environment. Acknowledging the roles played by the…

In our prior study the negative correlation between Topology, a behavioral measure of fluid reasoning, and adult age diminished with the increase in the level of expertise in a cognitively-demanding domain of expertise in the game of GO. The present fMRI study was designed to investigate neural substrates of Topology. The modified topology…

Researchers have examined inductive reasoning to identify different cognitive processes when participants deal with inductive problems. This article presents a prescriptive theory of inductive reasoning that identifies cognitive processing using a procedural strategy for making comparisons. It is hypothesized that training in the use of the…

A new analysis of data from 15 cognitive tasks completed by 93 subjects with scores on the Cattell Culture Fair test show that differences in Cattell score systematically affected performance on some tasks more than on others. Implications for theories of local and global differences in mental ability are discussed. (SLD)

Previous studies indicate increasing, significant univariate and multivariate correlation between reaction time (RT) tasks and intelligence. Using multiple regression analyses, data from an earlier study by Brown and Boretz were reanalyzed to further investigate the relationship between the speed at which an individual is able to process stimuli…

The influence of intelligence, self-concept, and causal attributions on metamemory and the metamemory-memory behavior relationship in grade-school children was studied. Following the assessment of intelligence, self-concept, and causal attributions, 105 children each from grades 3, 5, and 7 were given a metamemory interview and a sort-recall task.…

The Cattell Culture Fair Intelligence Test (CCFIT) was administered to a large sample of American, Nigerian, and Indian adolescents, and item data were examined for cultural bias. The CCFIT was designed to measure fluid intelligence, which is not influenced by cultural differences. Four different item analysis techniques were used to determine…

Studies of human problem solving have traditionally used deterministic tasks that require the execution of a systematic series of steps to reach a rational and optimal solution. Most real-world problems, however, are characterized by uncertainty, the need to consider an enormous number of variables and possible courses of action at each stage in…
