Introversion and extroversion are common personality traits that can vastly influence the way an individual’s cognitive abilities are utilized. Individuals will fall on this continuum based on how internally-focused or externally-focused they tend to be. As this is a central trait, it may seem logical that the level of introversion/extroversion could impact multiple, less central personality traits and cognitive abilities affecting many aspects of the individual’s life. The current study was designed to explore the possibility of differences in short-term memory, IQ scores, and errors made between extroverts and introverts. As extroverts tend to be more outward-focused, it may be logical to expect extroverts to have better short-term memory retrieval than introverts. It also may be logical to expect internally-driven introverts to perform better on the intelligent quotient assessment. Participants took a personality inventory to measure their levels of introversion and extroversion, along with an evaluation of their IQ and memory performance with errors. Results were analyzed in SPSS using three separate t-tests. Introverts performed significantly better than extroverts did on the intelligent quotient assessment, suggesting a higher level of attention to detail. Surprisingly, perhaps due to their impulsive and efficient nature, extroverts performed significantly better on the short-term memory task then did the introverts. They were also less likely to make as many errors when performing the short-term memory task. These findings suggest that there is a link between personality and cognitive abilities. Further implications suggest using personality research in education and utilizing different personalities in therapy treatments.
