Matters of Interest: The Objects of Research in Science and Technoscience

This discussion paper proposes that a meaningful distinction between science and technoscience can be found at the level of the objects of research. Both notions intermingle in the attitudes, intentions, programs and projects of researchers and research institutions—that is, on the side of the subjects of research. But the difference between science and technoscience becomes more explicit when research results are presented in particular settings and when the objects of research are exhibited for the specific interest they hold. When an experiment is presented as scientific evidence which confirms or disconfirms a hypothesis, this agrees with traditional conceptions of science. When organic molecules are presented for their capacity to serve individually as electric wires that carry surprisingly large currents, this would be a hallmark of technoscience. Accordingly, we propose research on the ontology of research objects. The focus on the character and significance of research objects makes this a specifically philosophical project.     

Nonlinear dynamics: theoretical perspectives and application to suicidology

Despite decades of research, the prediction of suicidal behavior remains limited. As a result, searching for more specific risk factors and testing their predictive power are central in suicidology. This strategy may be of limited value because it assumes linearity to the suicidal process that is most likely nonlinear by nature and which can be more adequately described and analyzed with nonlinear dynamics. The goal of moving nonlinear dynamics from theory to practice and to real-world phenomena can now be realized with Internet-based monitoring systems such as the Synergetic Navigation System.

Enhancing the learning of sport skills through external-focus feedback

The authors examined how the effectiveness of feedback for the learning of complex motor skills is affected by the focus of attention it induces. The feedback referred specifically either to body movements (internal focus) or to movement effects (external focus). In Experiment 1, groups of novices and advanced volleyball players (N = 48) practiced "tennis" serves under internal-focus or external-focus feedback conditions in a 2 (expertise) x 2 (feedback type) design. Type of feedback did not differentially affect movement quality, but external-focus feedback resulted in greater accuracy of the serves than internal-focus feedback during both practice and retention, independent of the level of expertise. In Experiment 2, the effects of relative feedback frequency as a function of attentional focus were examined. A 2 (feedback frequency: 100% vs. 33%) x 2 (feedback type) design was used. Experienced soccer players (N = 52) were required to shoot lofted passes at a target. External-focus feedback resulted in greater accuracy than internal-focus feedback did. In addition, reduced feedback frequency was beneficial under internal-focus feedback conditions, whereas 100% and 33% feedback were equally effective under external-focus conditions. The results demonstrate the effectiveness of effect-related, as opposed to movement-related, feedback and also suggest that there is a need to revise current views regarding the role of feedback for motor learning.     

Hindsight bias in gustatory judgments

Being in hindsight, people tend to overestimate what they had known in foresight. This phenomenon has been studied for a wide variety of knowledge domains (e.g., episodes with uncertain outcomes, or solutions to almanac questions). As a result of these studies, hindsight bias turned out to be a robust phenomenon. In this paper, we present two experiments that successfully extended the domain of hindsight bias to gustatory judgments. Participants tasted different food items and were asked to estimate the quantity of a certain ingredient, for example, the residual sugar in a white wine. Judgments in both experiments were systematically biased towards previously presented low or high values that were labeled as the true quantities. Thus, hindsight bias can be considered a phenomenon that extends well beyond the judgment domains studied so far.     

From self‐defeating to other defeating: Examining the effects of leader procrastination on follower work outcomes

This research examines the influence of leader procrastination on employee attitudes and behaviours. While previous studies have typically viewed procrastination as a form of self‐defeating behaviour, this research explores its effects on others in the workplace. In Study 1, using data collected from 290 employees, we demonstrate the discriminant and relative predictive validity of leader procrastination on leadership effectiveness compared with laissez‐faire leadership and directive leadership. In Study 2, based on dyadic data collected in three phases from 250 employees and their 23 supervisors, we found that leader procrastination was associated with follower discretionary behaviour (organizational citizenship behaviour and deviant behaviour). Additionally, job frustration was found to mediate the relationship between leader procrastination and follower outcomes. The quality of the leader–follower relationship, as a boundary condition, was shown to mitigate the detrimental effects of leader procrastination. Together, the findings suggest that leader procrastination is a distinct form of negative leadership behaviour that represents an important source of follower job frustration.

Practitioner points

• Leader procrastination is different from laissez‐faire and directive leadership and can be detrimental to followers.
• Job frustration mediates the relationship between leader procrastination and follower discretionary behaviour.
• Organizations should facilitate high‐quality LMX relationships as a method for mitigating the negative effects of leader procrastination.

     

Psychotherapie der Psychosen

In this paper the psychotherapy of patients with schizophrenic, schizoaffective and affective psychoses is outlined. Psychoanalytic, cognitive-behavioural and systemic approaches and their theoretical concepts as well as the therapeutic techniques are de- scribed. The settings of individual, group and family therapy are also presented. A survey of the types of psychoanalytic therapy with their eldest historic roots is given with the development of the various psychodynamic concepts for schizophrenic and affective psychoses including schizoaffective psycho-ses. The different kinds of psychotherapy are compared to each other with respect to the aims. Finally this paper deals with the effectiveness of the therapies and discusses the pros and cons of relatively short randomised controlled trials compared with long term psychotherapies without control groups.
