What Does Your Voice Reveal About You?

The first goal of the present study was to explore how 21 voice measures related to self-reported personality and communication styles. The second goal was to test the assertion of Trait Activation Theory (TAT) that traits are activated in relevant situations and that verbal behavior is the result of an interplay between individual differences and situations. The voice of 138 participants was measured in the lab via steady voice and continuous speech tasks, whereas personality and communication styles were self-reported using the HEXACO and Communication Styles Inventory. To test TAT, four scenarios were developed to activate the communication styles of Informality and Expressiveness. It was hypothesized that the activated communication styles will interact with relevant situations and will be expressed through changes in voice (i.e., pitch variation). Regarding the first goal, an explorative approach revealed that voice characteristics are informative mainly for the personality traits of Openness to Experience, Emotionality, and Conscientiousness and the communication styles of Emotionality and Questioningness. Regarding the second goal, the interactions between situations and communication styles provided mixed support for TAT. Implications and limitations of the study are discussed.

Why Not Interview?

Honesty-Humility is a valuable predictor in personnel selection; however, problems with self-report measures create a need for new tools to judge this trait. Therefore, this research examines the interview as an alternative for assessing Honesty-Humility and how to improve judgments of Honesty-Humility in the interview. Using trait activation theory, we examined the impact of interview question type on Honesty-Humility judgment accuracy. We hypothesized that general personality-tailored questions and probes would increase the accuracy of Honesty-Humility judgments. Nine hundred thirty-three Amazon Mechanical Turk workers watched and rated five interviews. Results found that general questions with probes and specific questions without probes led to the best Honesty-Humility judgments. These findings support the realistic accuracy model and provide implications for Honesty-Humility-based interviews.

Your Care Mitigates My Ego Depletion: Why and When Perfectionists Show Incivility Toward Coworkers

Drawing on ego depletion theory and trait activation theory, this study examines why and when employee perfectionism personality is linked with incivility toward coworkers. The study indulges ego depletion as a mediator between perfectionism personality and incivility toward coworkers, with coworker empathic concern moderating the relationship between perfectionism personality and ego depletion. A three-waved questionnaire was incorporated with sample of 253 employee-coworker dyads. Our findings demonstrate that dimensions of perfectionism personality are positively associated with incivility toward coworkers. In addition, our study confirms that ego depletion mediates the relationship between self-oriented perfectionism, other-oriented perfectionism, and incivility toward coworkers. Furthermore, our study shows that high levels of coworker empathic concern weakens the direct effect of self-oriented perfectionism on ego depletion along with the indirect effect of self-oriented perfectionism on incivility toward coworkers. Theoretical and practical implications of the study are discussed in the organizational context.

The Trickle-Down Effect of Responsible Leadership on Employees’ Pro-Environmental Behaviors: Evidence from the Hotel Industry in China

Based on the trickle-down effect model, social learning theory and trait activation theory, this study explores the mechanisms of multi-level responsible leadership on employees’ pro-environmental behaviors in the hotel industry in China. The results show that responsible leadership positively influences employees’ pro-environmental behaviors; mid-level responsible leadership significantly mediates the positive relationship between high-level responsible leadership and employees’ pro-environmental behaviors; and the perceived role of ethics and social responsibility positively moderates the relationship between responsible leadership and employees’ pro-environmental behaviors. The results of this study provide empirical support for further analysis of the “black box” of responsible leadership on employees’ pro-environmental behaviors, fill the gap of the trickle-down model in leadership, and provide new directions for sustainable value creation in hospitality industry organizations.

Machiavellian Leader Effectiveness

Research on the effectiveness of Machiavellian leaders has found contradictory results. By linking socioanalytic and trait activation theory to the Machiavellianism and leadership literature, we argue that political skill may explain these findings by moderating the relation between Machiavellianism and leadership effectiveness. Using a multisource design and moderated mediation analyses with 153 leaders, 287 subordinates, and 153 superiors, we show that leaders who are both strongly politically skilled and high on Machiavellianism successfully enact transformational leadership, mediating improved leader effectiveness. However, when leader political skill is low, high Machiavellianism is negatively associated with (subordinate-rated) transformational leadership, resulting in lower leader effectiveness ratings by superiors. We discuss these results in light of current research on Machiavellianism in leadership and work contexts.

On second thought… The influence of a second stage in the ultimatum game on decision behavior, electro-cortical correlates and their trait interrelation

In this study, we tested the influence of a second bargaining stage in an ultimatum game (UG) concerning behavioral responses, electro-cortical correlates and their moderations by the trait’s altruism, anger, anxiety and greed in 92 participants. We found that an additional stage led to more rejection in the 2-stage UG (2SUG) and that an increase in offer in the second stage led to more acceptance. The FRN during a trial was linked to expectance evaluation concerning the fairness of the offers, while midfrontal theta was a marker for the needed cognitive control to overcome the respective default behavioral pattern. The FRN responses to unfair offers were more negative for either low or high altruism in the UG, while high trait anxiety led to more negative FRN responses in the first stage of 2SUG, indicating a higher sensitivity to unfairness. Accordingly, the mean FRN response, representing the trait-like general electrocortical reactivity to unfairness, predicted rejection in the first stage of 2SUG. Additionally, we found that high trait anger led to more rejections for unfair offer in 2SUG in general, while trait altruism led to more rejection of unfair offers that were not improved in the second stage of 2SUG. In contrast, trait anxiety led to more acceptance in the second stage of 2SUG, while trait greed even led to more acceptance if the offer was worse than in the stage before. These findings suggest, that 2SUG creates a trait activation situation compared to the UG.

Effects of coworker's idiosyncratic deals on witness's creative process engagement: roles of responsibility for change and perceived exploitative leadership

Emerging research in the idiosyncratic deals literature is to examine its negative effects. Thus far, much remains unknown about how and when idiosyncratic deals are associated with employee creative process engagement. Invoking fairness heuristic theory and trait activation theory, we propose and test a model that coworker's idiosyncratic deals have a negative association with witness's creative process engagement through psychological contract violation. Furthermore, we theorize and test the combination of the responsibility for change and perceived exploitative leadership as important boundary conditions, associate interact with coworker's idiosyncratic deals to strengthen the positive impact on psychological contract violation, thereby reducing witness's creative process engagement. We use two time-lagged studies to provide support for these mediation and moderation effects, and also discuss the theoretical and practical implications of these findings.

A Mediated Moderation Model: Personality, Team Psychological Safety and Team Performance

Team performance as the foundation of organization in dealing with the complexity of the work and increasing the its competitiveness. Literature have shown that team psychological safety is an important predictor of team performance. This study use Trait Activation Theory to develop and present a model that aims to find the interaction between personality, team psychological safety and team performance. Regarding personality framework, this study uses the perspective of The Five-Factor Model. The results suggest that: First, the indirect effects of Conscientiousness personality on team performance will be stronger in (a) work that requires freedom and (b) work with high attention/detail requirements. Second, the indirect effects of extraversion personality on Team performance will be stronger in (a) jobs that require high social skills, (b) jobs with a high level of competition requirements, and (c) work where someone must often deal with unpleasant responses. Third, the indirect effect of openness personality on team performance will be stronger in (a) work that requires freedom and (b) work with high requirements of creativity.
