Establishing the next generation at work: leader generativity as a moderator of the relationships between leader age, leader-member exchange, and leadership success

In this study, the authors investigated leader generativity as a moderator of the relationships between leader age, leader-member exchange, and three criteria of leadership success (follower perceptions of leader effectiveness, follower satisfaction with leader, and follower extra effort). Data came from 128 university professors paired with one research assistant each. Results showed positive relationships between leader age and leader generativity, and negative relationships between leader age and follower perceptions of leader effectiveness and follower extra effort. Consistent with expectations based on leadership categorization theory, leader generativity moderated the relationships between leader age and all three criteria of leadership success, such that leaders high in generativity were better able to maintain high levels of leadership success at higher ages than leaders low in generativity. Finally, results of mediated moderation analyses showed that leader-member exchange quality mediated these moderating effects. The findings suggest that, in combination, leader age and the age-related construct of generativity importantly influence leadership processes and outcomes.     

Hot Sauce,toy guns,and graffiti: A critical account of current laboratory aggression paradigms

In 1996, Tedeschi and Quigley published a review of laboratory aggression research that included many damning criticisms of the genre. This paper revisits Tedeschi and Quigley's critique, and examines the ways that subsequent researchers have addressed the weaknesses they identified. In particular, it examines three new laboratory aggression paradigms (Hot Sauce, Bungled Procedure, and Experimental Graffiti Paradigms) that have attempted to improve upon the “classic” paradigms (Teacher/Learner & Essay Evaluation Paradigms, Competitive Reaction Time Game, Point Subtraction Aggression Paradigm, and Bobo Modelling Paradigm). In each case, this review will show, that although some aspects of the new designs are indeed improvements, many of Tedeschi and Quigley's arguments still apply. In conclusion, this investigation will identify a number of factors that future laboratory aggression researchers should consider. These include: The perceptions and motivations of the aggressor; the apparent distance between the aggressor and the target; the availability of non‐aggressive response options; the problems of demand characteristics, permissive cues and agentic shift; the differences between proactive and reactive aggression, and the distinction between overt and covert forms of aggression.

Kombination von Settings und Verfahren in der Psychotherapie

Literature research and own clinical experiences confirm the significance of a combined use of settings and methods in the area of inpatient and outpatient psychotherapy. For inpatient treatment, the combined use of methods, such as individual psychotherapy, group therapy, creative therapies, and sport, are an essential part of the treatment. In outpatient treatment, the regulations of the German insurance do not permit such combinations. Nevertheless, they occur and are often proactively initiated by the patients. The various combined use of psychotherapy and psychotropics is very well studied, but also the combination of settings, i.e. supplementary inpatient treatment, day treatment, and outpatient treatment have to be considered. While administering their therapies, psychotherapists should keep in mind possibly concurrently ongoing treatments as well as former therapies and their effects on the patients. With the exception of combinations with psychotropic treatment, there exist almost no empirical data in this important field.     

Modeling how, when, and what is learned in a simple fault-finding task

We have developed a process model that learns in multiple ways while finding faults in a simple control panel device. The model predicts human participants' learning through its own learning. The model's performance was systematically compared to human learning data, including the time course and specific sequence of learned behaviors. These comparisons show that the model accounts very well for measures such as problem-solving strategy, the relative difficulty of faults, and average fault-finding time. More important, because the model learns and transfers its learning across problems, it also accounts for the faster problem-solving times due to learning when examined across participants, across faults, and across the series of 20 trials on an individual participant basis. The model shows how learning while problem solving can lead to more recognition-based performance, and helps explain how the shape of the learning curve can arise through learning and be modified by differential transfer. Overall, the quality of the correspondence appears to have arisen from procedural, declarative, and episodic learning all taking place within individual problem-solving episodes.     

Psychometric evaluation of the Multidimensional Assessment of Fatigue scale for use with pregnant and postpartum women

Although fatigue is a common experience for pregnant women and new mothers, few measures of fatigue have been validated for use with this population. To address this gap, the authors assessed psychometric properties of the Multidimensional Assessment of Fatigue (MAF) scale, which was used in 2 independent samples of pregnant women. Results indicated that the psychometric properties of the scale were very similar across samples and time points. The scale possesses a high level of internal consistency, has good convergent validity with measures of sleep quality and depression, and discriminates well from a measure of social support. Contrary to previous evaluations of the MAF, data strongly suggest that the scale represents a unidimensional construct best represented by a single factor. Results indicate that the MAF is a useful measure of fatigue among pregnant and postpartum women.

Effects of menstrual cycle phase on reporting levels of aggression using the buss and perry aggression questionnaire

The Aggression Questionnaire [Buss and Perry, 1992, Journal of Personality and Aggression, vol. 63, pp. 452–459] was administered to women at menses and during the midluteal phase of their menstrual cycles to assess changes in reporting aggressive behavior as a function of menstrual phase. Men served as a control group, and also received the questionnaire twice, once at session I and once at session II. Women at menses reported a significantly higher level of physically aggressive behavior than during the midluteal phase. A similar but non‐significant trend was found for reporting verbal aggression. There were no changes in reporting of anger or hostility across the menstrual cycle. This produced a significant sex‐difference on reporting physical aggression between men and women at the midluteal phase but not at menses. Aggr. Behav. 29:531–538, 2003. © 2003 Wiley‐Liss, Inc.
