61 A- und B-Jugendspieler durchliefen eine Reihe psychologischer Tests zu impliziten und expliziten Motiven, zur Selbstregulation, Handlungs-Lageorientierung, Willensbahnung und zur Persönlichkeit. 52 dieser Spieler nahmen einige Wochen danach an einem experimentellen Testspiel auf kleinem Feld teil. Insgesamt sechs Spiele wurden gespielt, die erste Halbzeit unter normalen Bedingungen, die zweite Halbzeit unter erhöhtem mentalen Druck. Stress wurde ausgelöst durch eine unerwartete Bewertungssituation während der Halbzeitpause. Wichtige Erfolgsvariablen wie die Anzahl erzielter Tore und Scorerpunkte konnten über Faktoren der Persönlichkeit und der Willensbahnung erklärt werden und anhand von Varianzen des Passverhaltens als Handlungsschnelligkeit erkannt werden. Die jeweiligen Vereine konnten als dynamische Systeme mit spezifischen Charakteristika beschrieben werden, welche sich nachhaltig im Spielverhalten wieder finden lassen (u. a. durch die Dynamik der Cortisolregulation). Eine neu entworfene Methodik der Spielanalyse (Passspielanalyse durch Intervallbildung) führte zu einem Gros der Ergebnisse.

Everyday life experience tells us that individual differences apparently matter. Although confronted with the same situation, individuals seem to act and react in different ways. On a behavioral and self-report level, individual differences are well documented. Over the past decades, they have been systematically assessed and embedded in complex theories of personality. On the other hand, the influence of personality differences on cognitive processes and their cerebral substrate is far from being entirely understood. Especially the complex interplay of two or more aspects, like individual differences (e.g., in motivational processes), cognitive functions (e.g., intuition), cerebral activation and lateralization, and humoral processes (e.g., cortisol), are seldom aim of psychological research. The Personality Systems Interaction (PSI) theory (Kuhl, 2000, 2001) provides a theoretical framework, which tries to incorporate the above-mentioned aspects. On the background of PSI theory, the aim of the present work was to investigate differences in motivational processing and how they are related to hemispherical asymmetries, cognitive processing, and humoral reactivity. Each of the three research articles presented throughout the present work tackles different aspects of this general research question. For this, a variety of different methodological techniques were used (e.g., questionnaires, implicit measures, electroencephalography, etc.) to approach the aforementioned goal. The first research paper presented in the current work examines the relationship between the implicit affiliation motive and intuition, as a form cognitive processing. Previous research already demonstrated that affiliation-laden primes facilitate intuitive thought (Kuhl & Kazén, 2008). Therefore, it could be expected that trait affiliation motive would also be correlated with intuition. Intuition in turn is thought to be a function of right hemispheric processes. An association between trait affiliation and intuition could therefore indirectly indicate a lateralization to the right side for affiliation. With the first study of the present work, the author tested this association. Thirty-nine students filled in the Operant Motive Test for the assessment of implicit affiliation, a variant of the Thematic Apperception Test. Then, 9 months later, participants engaged in a Remote Associates Test in which they intuitively had to indicate whether three words are semantically related. As expected, the implicit affiliation motive significantly predicted the accuracy of identifying related word triads. No other implicit or explicit measure, nor state or trait positive affect was associated with intuition. With the second research article, the aforementioned indirect association between affiliation and lateralized processing was investigated more directly. Previous research on relationships between personality and EEG resting state frontal asymmetries mainly focused on individual differences with respect to motivational direction (i.e., approach vs. withdrawal). By contrast, the second article investigated frontal asymmetries as a function of individual differences in implicit affiliation motive. The goal was not only to contribute to the validation of PSI theory and to the investigation of the laterality of the affiliation motive, but also to disentangle the contribution of different social motives to frontal EEG asymmetries. The consideration of social motives, such as the affiliation motive, seemed to be necessary, because a recent meta-analysis showed that the association between approach motivation and frontal asymmetries is negligible or that unidentified moderators drive this association. From previous research and the results from the first paper presented in the current work, an association between affiliation motive and right frontal activity was predicted. Additionally, to control for possible associations with motivational direction, trait behavioral inhibition, behavioral activation, and anger were assessed and correlated with frontal asymmetries. Seventy-two right-handed students were tested. As expected and in accordance with the findings from the first paper, the author found that relative right frontal activity (indicated by low alpha frequency power) was associated with the affiliation motive. To explore brain regions responsible for this association at scalp sites, a source localization algorithm was applied. Intracranial distribution of primary current densities for the alpha band spectrum in source space was estimated and correlated with implicit affiliation scores. A significantly correlating area could be identified in the right ventromedial prefrontal cortex (Brodmann Area 10). No other associations at scalp sites or in source space could be found for motivational direction. The third research article presented in the current work highlights motivational differences slightly different from those presented above. It deals with dynamic motivational processes, such as action orientation, and how they moderate the association between cerebral asymmetries and the physiological stress reaction. Hypothalamus pituitary adrenocortical (HPA) system activity and frontal brain asymmetries have both been linked to stress and emotion but their relationship remains unclear, especially when additionally considering individual differences. Therefore, participants were exposed to public speaking stress while salivary cortisol levels (as a marker of HPA activity) and resting frontal EEG alpha asymmetries were assessed before and after stress induction. The results indicate that higher post stressor cortisol levels were associated with higher relative left frontal activity. State oriented participants showed a stronger association between cortisol response and left frontal activity than action oriented participants. The above-mentioned findings are discussed referring to PSI theory and their possible implications. Additionally, shortcomings of the present research and possible remedies will be presented.

It has been established that specific implicit motive profiles predict job performance and career progression. However, it has not been a topic of examination to distinguish the role implicit motives play in developing certain leadership behaviors that, in turn, lead to job performance and success. My hypotheses were that, firstly, the ownership structure of organizations will play a distinct role in establishing the implicit motives that lead to managerial progression and, secondly, implicit motives will better predict long-term (general) leadership behaviors whereas explicit motives will better predict situation-specific leadership behaviors. In Study 1 the effects of three types of organizations as well as the effects of executive level/responsibility on the implicit motive profiles of managers were assessed. The types of organizations were family-owned and -led, foreign-owned and family-led, as well as publicly-owned and -led after previous family ownership. Data collection took place between the years 2004 and 2010. It could be demonstrated that an organization's ownership structure was significantly correlated with the implicit motives of managers, while executive level/responsibility was not. In Study 2 implicit and explicit motives were tested as predictors of competency scores in three separate cases. Case 1 consisted of data from one pharmaceutical company based in Spain; Case 2 encompassed data from 13 different companies in several industries and countries; and Case 3 included data for one global services and technology company with headquarters in the US. Data were collected between the years 2002 and 2010. The results yielded were inconsistent across cases. Unexpectedly, both implicit and explicit motives were predictive of competency scores. Beside the main effects, interaction effects of implicit motives and congruity between implicit and explicit motives were considered. I also included implicit motives of the CEO, as scored in the letter to the shareholder, as well as the congruence of manager implicit motives with CEO implicit motives into these analyses. Effects of these variables were also inconsistent across cases. Study 3 extended previous investigations to explore the effects of implicit and explicit motives as well as leadership styles on organizational climate. Organizational climate was observed from two perspectives: actual climate as perceived by subordinates and ideal climate as desired by managers. Based on management data collected in the years 2000 through 2008 for four companies in the agriculture, mining, telecommunications and transportation sectors, findings indicated that only leadership styles consistently accounted for changes in organizational climate. However, ideal desired climate could also be partially explained by managers’ explicit motives in some cases. As expected, implicit motives did not predict organizational climate in any of the analyses.

Approach and Avoidance motivation are two of the oldest psychological concepts of behavior. Whereas approach motivation corresponds to the strong urge to come close to an object, state or person (e.g., during states of sexual attraction), avoidance motivation corresponds to the strong urge to avoid a specific situation (e.g., evade a dangerous situation). This dissertation deals with the electroencephalographic (EEG) markers of approach and avoidance motivation, assessed using event-related-potentials and brain oscillations in a low frequency band (alpha band). The first manuscript shows a left hemispheric processing advantage for approach-related stimuli. Specifically, we report a reduction in the alpha band (as an inverse maker for cortical activity) for erotic, but not for control pictures. Notably, we are the first to report alpha-asymmetries using an event-related design. In the second manuscript we describe evidence (a) for separating approach motivation from the affective dimensions of valence and arousal and (b) for an enhanced attention-related early EEG amplitude (P1 component) only for approach-related but not for control pictures. Up to our knowledge, we are the first to associate the P1 component with approach motivation. In the third manuscript we report an enlarged P1 component for increased avoidance motivation, as measured by the negative affect scale of the German Positive and Negative Affect Schedule (PANAS; Krohne, Egloff, Kohlmann, & Tausch, 1996). In more detail, state negative affect correlated positively with the P1 component, as a marker of increased selective attention. As far as we know, no study ever showed that state negative affect has an influence on attention. Therefore, we consider these findings regarding previous findings on trait negative affect, specifically on anxiety and phobia. All findings are discussed in the context of established views and models, such as Personality Systems Interaction (PSI) theory, hypervigilance theory, wanting versus liking and are also integrated into the findings from neuroimaging studies.
