The Effect of Reasoning Ability Enhancement on Academic Achievement of Iranian Foreign Language Learners

Leila Kamelifar


The ability to solve novel problems without retrieving information from memory and using logical reasoning is called fluid intelligence (Cattell, 1963). Fluid intelligence (Gf) is usually referred to as the ability to identify patterns and relationships with the help of reasoning. However, extensive studies (performed by Jaeggi et al., 2008; Vigneau & Bors, 2008) have shown that Gf can be improved and strengthened through training in its components of which inductive fluid reasoning is remarkable. In 1949, Cattell developed a test to measure cognitive abilities such as Gf . The underlying theories lagging behind the present research were the ideas of educability of Gf and the commonality shared by Cattell’s test and English conjunctive adverbs. Since the implementation of Cattell’s test and application of connectors involve different levels of fluidly inductive reasoning, the exposure to Cattell’s test through application of connectors might improve the test scores of writing test. To this end, a total number of 60 junior students at participated in this study. The experimental group had 10 sessions of treatment in learning connectors and Cattell’s test. The results showed the exposure to Cattell’s test could increase the writing scores of English conjunctive adverbs. Finally, based on the findings of this study, a cognitively tentative perceptual framework was proposed.
