Intelligence Testing Article Analysis



PSY/450 Diversity and Cultural Factors in Psychology


     Intelligence testing has long been a controversial task of recognizing the cognitive processes by which people acquire and apply knowledge; specifically “recognition, categorization, thinking and memor[ization]” (Shiraev & Levy, 2010, p. 121).  Regardless, cross-culturally intelligence is tested, even at the earliest of ages in infancy, in an effort to identify when and where intelligence stems (but reliability and validity of infant tests remain questionable).  Peterson (1922) describes intelligence as “one’s ability to be affected by a wide range of circumstances and to delay reaction …with respect to their bearing on the attainment of any particular end” (p. 388).  With that in mind, it is possible to see how general intelligence and multiple intelligence theories are viewed and evaluated when testing is applied to children. 
General Intelligence Theory
     In trying to explain the differences among individuals using the general intelligence theory or g theory, Charles Spearman (1863-1945) suggests that human intelligence is portrayed as some type of measureable energy.  As such, he led the quest for tests that could measure the g factors correlating to others in deeming intelligence levels common to all tests (Loh, n.d.).  Thus, if someone’s IQ scores are high on one test he or she will typically score high on other IQ tests and vice versa if his or her scores are low.  That stated, “Lewis and McGurk argue for the failure of any predictive power in present tests of infant intelligence” …but indicate such tests “may [only] reflect [an] infant’s current mental capacity” (McGlannan, Matteny Jr, Wilson, Lewis,  & McGurk, 1974, p. 37).  Bayley, according to McGlannan, et. al., (1974), argues that rapid growth of intelligence during the infancy period as the reason for the inability to measure stable, predictable g factors in the very young, which could reinforce a skills based intelligence rather than an innate ability.
Multiple Intelligence Theory
      First proposed by Howard Gardner in 1983, his work initially suggests that there are seven types of intelligence: Linguistic intelligence, logical-mathematical intelligence, musical intelligence, bodily-kinesthetic intelligence, spatial intelligence, interpersonal, and intrapersonal intelligence.  However, after additional research, Gardner and his colleagues considered adding additional intelligences under the umbrella of multiple intelligences (MI).  They are naturalist intelligence, spiritual intelligence, moral intelligence, and existential intelligence, but to Gardner only naturalist intelligence adds the core values that describe intelligence, thus increasing his MI list to eight intelligences (Smith, 2008).  As mentioned, while testing during infancy may have little or no predictive validity; such tests may have a high validity on measuring a child’s cognitive abilities.  Although, the processes by which one acquires intelligences vary based on a person’s “environmental, social, psychological, and cultural circumstances,” corroborating Gardner’s ideals of eight levels or avenues, if you will, of developing intelligence (Cole, et. al., 1971, as restated by Shiraev & Levy, 2010, p. 127).       
Evaluating the Effectiveness of Intelligence Testing
     Cross-culturally intelligence testing itself can prove to be difficult as testing formats are largely provided in Western terminology and do not account for language, economic, nor cultural variables.  Shiraev and Levy (2010) provide an example of internal bias as familiar ethnic group verbiage, leading to higher scores for one group over another.  Furnham and McClelland (2009) concur that “word usage in verbal intelligence testing has a significant effect on test scores” (p. 544).  By changing a single word to a high frequency word (e.g., from precede to before), more people are able to comprehend quicker, thus achieving higher scores.  Therefore, when evaluating intelligence there are many things that must be considered culturally, such as one’s cultural vocabulary, cultural literacy, cognitive style, and age.  After all, “the people, as representatives of a particular culture, define intelligence” (Shiraev & Levy, 2010, p. 135).  
Conclusion
     Regardless of whether one believes there is a single determining g factor  to intelligence or a series of eight MIs, the process of uncovering someone’s mental abilities and capacity to problem-solve can be challenging.  Rapid growth in infancy makes it difficult to validate Spearman’s theories about general intelligence (g theory) at such a young age, according to the Bayley Scales of Infant Development (McGlannan, et. al., 1974).  While Gardner’s theories branch out to allow for more diverse intellectual abilities: linguistic, logical-mathematical, musical, bodily-kinesthetic, spatial, interpersonal, intrapersonal, and naturalist intelligence; thus taking into account the cognitive processes of intelligence.  While evaluating intelligence testing in general can be difficult because of the many biases, applying IQ testing to infants is controversial and unreliable for any predictive use of intelligence.  However, that does not mean changes in the future will not make such testing’s highly affective and useful so that globally everyone’s intellectual opportunities can improve.
