  • Current textbooks, websites, research articles, and popular resources have stated that gifted individuals have longer and more pronounced responses to stimuli than the general population. This overexcitable nature of gifted persons has provided a commonly used lens to conceptualize, identify, and understand giftedness and gifted persons’ behaviors. Yet there are reasons to be skeptical about the evidence demonstrating that the gifted population is more overexcitable than the nongifted population. A meta-analysis was conducted to investigate the existence and strength of the giftedness–overexcitability (OE) relationship as presented in a number of studies comparing the OE scores of intellectually gifted and nongifted samples. Gifted samples were found to have higher mean OE scores than nongifted samples. However, the effect size for psychomotor OE was not statistically significant, while the effect sizes for the emotional and sensual OEs were small. Calculated effect sizes for intellectual and imaginational OEs were medium. A number of important limitations and implications exist.

  • Many scholars of gifted education have often argued and believed that gifted individuals are neurologically overexcitable while non-gifted persons are not (Chang & Kuo, 2013; Harrison & Haneghan, 2011; Piechowski, 1979, 2006; Silverman, 2000a; Siu, 2010; Tieso, 2007a). This means that gifted persons are more sensitive, intuitive, empathic, and physically and emotionally aware. Some scholars have suggested that this significant degree of overexcitability may even mean that gifted persons are morally superior to non-gifted persons (Silverman, 1994). Over the past thirty years, this relationship between overexcitability (OE) and giftedness has become increasingly popular, as many websites, textbooks, and researchers have asserted it as true. These resources have also advocated a particular treatment and understanding of gifted persons due to their overexcitable nature.Recently, however, some scholars have questioned the validity of the giftedness overexcitability relationship (Mendaglio, 2002; Pyrt, 2008; Tillier, 2009a). So, while the past thirty years have seen a rise in the perception that gifted persons are overexcitable (Silverman, 2008), these scholars have contended that there is actually little empirical data demonstrating this relationship (Mendaglio; Pyrt; Tillier).Using a systematic review of studies that compared gifted and non-gifted samples' OE scores, this dissertation attempted to provide some clarity to this burgeoning debate. This process involved a research synthesis that used a priori established criteria to identify, describe, and evaluate the findings and methodologies of a body of literature's most rigorously conducted studies (Petticrew, 2001). The evaluation phase of the systematic review included both qualitative and quantitative techniques. These findings revealed that it is unclear that gifted individuals are significantly more overexcitable than non-gifted individuals. Consequently, researchers, practitioners, and gifted persons themselves should reconsider the relationship between giftedness and overexcitability.
