Gender Differences in Motor Coordination at Young Students at Psychology

The instruments: Two hand coordination test from Vienna Tests System. Results highlight that young female students have the ability to calibrate, correct the errors and to learn from errors statistically significant than young male students and the young male students are statistically significant more precisely in competing the task.

The incremental validity of the dark triad in predicting driving aggression.

This research tested the association between the Dark Triad and driving aggression as well as the incremental validity of the Dark Triad in predicting aggressive driving and the mediation role of the Dark Triad in the relationship between Big Five personality factors and aggressive driving. 274 undergraduate students in Study 1 and 95 amateur drivers in Study 2 completed measures of the Dark Triad (Machiavellianism, Narcissism and Psychopathy), the Big Five personality factors and the aggressive driving expression. Results showed that all the Dark Triad traits were related to aggressive driving behavior in both Study 1 and Study 2 and that the Dark Triad predicted driving aggression after the effect of the Big five personality factors was controlled, with Psychopathy being the strongest predictor of driving aggression in both Study 1 and Study 2. Machiavellianism and Psychopathy mediated the relationship between Emotional Stability, Agreeableness, Conscientiousness on one hand and aggressive driving on the other hand.

The link between personality, aggressive driving, and risky driving outcomes – testing a theoretical model

This study tested a theoretical model of the relationship between the Big Five Personality Factors, aggressive driving and ‘risky driving outcomes’ (accidents, traffic tickets, and license suspension). It also tested the mediation effect of aggressive driving in the relationship between the five factor personality model and risky driving outcomes. Structural equation modeling was used to analyze the 293 participants’ responses. Bivariate correlations showed that aggressive driving was negatively related to emotional stability, agreeableness, and conscientiousness and positively related to risky driving outcomes. Agreeableness was negatively related to accidents, tickets, and license suspension. Conscientiousness was negatively related to tickets. The structural model was supported by data in which agreeableness predicted risky driving outcomes. Emotional stability, agreeableness, and conscientiousness predicted aggressive driving, which in turn predicted risky driving outcomes. Aggressive driving was shown to be a mediator in the relationship between agreeableness and risky driving outcomes.

The HEXACO Model of Personality and Risky Driving Behavior

This research tested the association between the HEXACO personality model and risky driving behavior as well as the predictive power of the HEXACO model in explaining risky driving behavior compared with the Big Five model. In Sample 1, 227 undergraduate students completed measures of the HEXACO personality model, the Big Five model, and driving aggression. In Sample 2, 244 community respondents completed measures of the HEXACO personality model, the Big Five model, and driving styles. Results showed that the Honesty–Humility factor is an important addition to personality models that aim to explain risky driving behavior as being related to all forms of driving aggression as well as to maladaptive and adaptive driving styles and having incremental validity in predicting verbally aggressive expression, risky driving, high-velocity driving, and careful driving. Moreover, compared with the Big Five model, the HEXACO model had better predictive power of aggressive driving.
