RESUMO

The current research investigated the relationship of some leadership behaviors, thereafter called Executive Leadership, with the concentration levels of testosterone found in the human saliva. The research also investigated the corelations among Executive Leadership behaviors, the digital ratio (2nd:4th) and the concept of internal Locus of Control. The digit ratio is defined as the division of the length of 2nd finger (index finger) by the length of 4th finger (ring finger). Such study aimed at providing additional subsidies for adopting a biosocial model to understanding leadership. A group of 169 male students enrolled in a postgraduation program was selected as participants. They answered an Executive Leadership behaviors self assessment questionnaire (self perception). The questionnaire was based on the Inventário Fatorial de Personalidade - IFP. The subjects were grouped based on their questionnaires scores: (1) low self perception of leadership (BPL), (2) average self perception of leadership (MPL) e (3) high self perception of leadership (APL). Through statistic analysis the 10 most characteristic participants of each of the three groups were selected. These 30 participants were submitted to collection and analysis of saliva testosterone concentration level, using the kit provided by Salimetrics Inc (catalog nº 1-2412). On top of that, their index and ring fingers´s length was measured, as means to obtain data to calculate the digital ratio. The Rotter Scale was used to assess the Locus of Control (LoC). The main hypothesis - the three groups would differ with regards to the concentration of testosterone found in their saliva - was statistically confirmed, therefore there is direct positive relationship between self perception of leadership and concentration of T in the saliva. The hypothesis of inverse relationship between self perception of leadership and Digit Ratio was not confirmed. The research data also did not confirm relationship between internal Locus of Control and self perception of leadership. The results obtained through the research offer an important contribution for future studies of integrated biosocial leadership models.
