Although researchers predominately test for linear relationships between variables, at times there may be theoretical and even empirical reasons for expecting nonlinear functions. We examined if the relation between intelligence (IQ) and perceived leadership might be more accurately described by a curvilinear single-peaked function. Following Simonton's (1985) theory, we tested a specific model, indicating that the optimal IQ for perceived leadership will appear at about 1.2 standard deviations above the mean IQ of the group membership. The sample consisted of midlevel leaders from multinational private-sector companies. We used the leaders' scores on the Wonderlic Personnel Test (WPT)-a measure of IQ-to predict how they would be perceived on prototypically effective leadership (i.e., transformational and instrumental leadership). Accounting for the effects of leader personality, gender, age, as well as company, country, and time fixed effects, analyses indicated that perceptions of leadership followed a curvilinear inverted-U function of intelligence. The peak of this function was at an IQ score of about 120, which did not depart significantly from the value predicted by the theory. As the first direct empirical test of a precise curvilinear model of the intelligence-leadership relation, the results have important implications for future research on how leaders are perceived in the workplace.

- Language, learning, and memory in children with and without single-suture craniosynostosis. [Journal Article]
- JNJ Neurosurg Pediatr 2016; 17(5):578-88
- CONCLUSIONS: Children with SSC continue to show poorer performance than controls on language, learning, and memory tasks at early elementary school age, even when controlling for known confounders, although mean differences are small. Multidisciplinary care, including direct psychological assessment, for children with SSC should extend through school age with a specific focus on language and conceptual learning, as these are areas of potential risk. Future research is needed to investigate language, memory, and learning for this population during the middle to high school years.
- Comparison of three ADHD screening instruments in college students of varying cognitive ability. [Journal Article]
- JAJ Atten Disord 2013; 17(5):449-54
- CONCLUSIONS: All three screeners exhibited acceptable reliability levels. Criterion validity was demonstrated by the relationship between the CAARS's inattention subscale and self-reported cases of ADHD. Criterion validity was also seen in the relationship found between the CAARS's hyperactivity/restlessness subscale and the total course performance even after controlling for cognitive ability. Contrary to past research cognitive ability exhibited a weak but significant relationship with a few screeners and screener subscales.

150 young bankers estimated their IQ (Academic/Cognitive Intelligence) and EQ (Emotional Intelligence) before taking an IQ test. Pearson correlations were r = .40 and .41 between IQ test (Wonderlic Personnel Test) scores (M = 32.8) and IQ estimates (M = 27.9) and EQ estimates, respectively. Women's mean self-estimated IQ was significantly lower than men's.

- CONCLUSIONS: Data from less than an hour's worth of testing pupils could predict school exam results 6 months later. These tests could, therefore, be used to reliably inform important decisions about how pupils are taught.
- The NFL combine: does it predict performance in the National Football League? [Journal Article]

The authors investigate the correlation between National Football League (NFL) combine test results and NFL success for players drafted at three different offensive positions (quarterback, running back, and wide receiver) during a recent 6-year period, 1999-2004. The combine consists of series of drills, exercises, interviews, aptitude tests, and physical exams designed to assess the skills of promising college football players and to predict their performance in the NFL. Combine measures examined in this study include 10-, 20-, and 40-yard dashes, bench press, vertical jump, broad jump, 20- and 60-yard shuttles, three-cone drill, and the Wonderlic Personnel Test. Performance criteria include 10 variables: draft order; 3 years each of salary received and games played; and position-specific data. Using correlation analysis, we find no consistent statistical relationship between combine tests and professional football performance, with the notable exception of sprint tests for running backs. We put forth possible explanations for the general lack of statistical relations detected, and, consequently, we question the overall usefulness of the combine. We also offer suggestions for improving the prediction of success in the NFL, primarily the use of more rigorous psychological tests and the examination of collegiate performance as a job sample test. Finally, from a practical standpoint, the results of the study should encourage NFL team personnel to reevaluate the usefulness of the combine's physical tests and exercises as predictors of player performance. This study should encourage team personnel to consider the weighting and importance of various combine measures and the potential benefits of overhauling the combine process, with the goal of creating a more valid system for predicting player success.

The present investigation examined the concurrent validity of the Wonderlic Personnel Test and Woodcock-Johnson-Revised Tests of Cognitive Ability which were administered to 37 college students, 27 women and 10 men, who ranged in age from 18 to 54 years (M=27.1, SD=8.7). Analysis yielded significant correlation coefficients between the Wonderlic Total score and the score for the WJ-R Broad Cognitive Ability Standard Battery (r = .55) and the Comprehensive Knowledge score (r= .34). Performance on the Wonderlic was not significantly correlated with fluid reasoning skills (r=.26) but was most strongly associated with overall intellectual functioning, as measured by the Woodcock-Johnson Standard Battery IQ score. While scores on the Wonderlic were more strongly associated with crystallized than fluid reasoning abilities, the Wonderlic test scores did not clearly show convergent and divergent validity evidence across these two broad domains of cognitive ability.

This study examined whether demand characteristics concerning music can change subjects' performance on the Wonderlic Personnel Test of intelligence. Participants (N= 60) were randomly assigned and informed either that Mozart's music typically enhances cognitive performance or diminishes it. They then completed the Wonderlic Personnel Test while listening to a Mozart piano sonata. The subjects with a positive set answered significantly more items correctly on the test (14%) than those with a negative set (p = .03). This result may hold implications for the study of the 'Mozart effect'.

We test the hypothesis that polymorphisms of the brain regulator genes MCPH1 and ASPM contribute to variations in human brain size and its correlates. We measured general mental ability, head circumference and social intelligence in 644 Canadian adults (496 Caucasians, 36 Orientals, 84 Mixed Race/Other and 28 Blacks; 257 men and 387 women). The gene polymorphisms were assessed from buccal DNA; mental ability by Wonderlic Personnel Test and Multidimensional Aptitude Battery; head circumference by stretchless tape; and social intelligence by prosocial attitude questionnaires. Although all measures were construct valid and the allele frequencies showed expected population differences, no relationship was found between the genes and any of the criteria. Among Caucasian 18-25 year olds, for example, the two mental ability tests correlated with each other (r=0.78, N=476, p<0.001), with head circumference (r=0.17, N=182, p<0.05) and with prosocial attitudes (r=0.23, N=182, p<0.001).
