Hypo<strong>the</strong>ses 7: Personality traits moderate <strong>the</strong> relationship between managerial tacit knowledge and
individual performance.
Table 4 shows <strong>the</strong> results <strong>of</strong> <strong>the</strong> hierarchical regression analysis related to H7. Findings indicate that
personality traits moderate <strong>the</strong> effect <strong>of</strong> managerial tacit knowledge on individual performance in <strong>the</strong>
typology depicted in Figure 1 as pure moderator and quasi moderator.

Overall managerial tacit knowledge and associated sub-scales (managerial o<strong>the</strong>rs, task and self)
were entered into step 1 <strong>of</strong> <strong>the</strong> regression analysis. In step 2 <strong>the</strong> moderator variables, agreeableness,
openness, and conscientiousness were entered. Interaction terms were entered into step 3 <strong>of</strong> <strong>the</strong>
regression model. Managerial tacit knowledge variables entered in step 1 account for 6.3% <strong>of</strong> <strong>the</strong>
variance in individual performance. Of <strong>the</strong> three sub-scales associated with <strong>the</strong> managerial tacit
knowledge variable, only ‘managing self’ was found to influence individual performance (β = -0.183, t
=-3.199, p =.002).
In <strong>the</strong> second step, <strong>the</strong> moderator factors, agreeableness, openness, and conscientiousness were
entered into <strong>the</strong> equation to examine <strong>the</strong>ir effects as predictors <strong>of</strong> individual performance. When,
<strong>the</strong>se moderator factors were entered in <strong>the</strong> regression model, <strong>the</strong> R² increased from 6.3% to 16.5%
accounting for a change <strong>of</strong> approximately 10% in individual performance.
In <strong>the</strong> third step, <strong>the</strong> 12 interaction terms were entered into <strong>the</strong> model. It can be seen from Table 4
that <strong>of</strong> <strong>the</strong> variance explained by interaction terms, 24.1% was significant (p
