In a controlled laboratory experiment we ask participants to give a detailed answer to an open question. The treatment variable is whether or not they see the phrase “thanks in advance.” Our participants react to the treatment by exerting less effort in answering the request even though they perceive the phrase as polite.

Flow-Erleben wird als Motivationsursache gesehen und soll den Weg zu Freude und Glück darstellen. Insbesondere wegen dem oft zitierten Fachkräftemangel in naturwissenschaftlichen und technischen Berufen ist eine Motivationssteigerung in naturwissenschaftlichen Unterrichtsfächern wichtig. Denn trotz Leistungssteigerungen in internationalen Vergleichstests möchten in Deutschland deutlich weniger Schüler*innen einen solchen Beruf ergreifen als in anderen Industriestaaten. Daher gilt es, möglichst früh Schüler*innen für naturwissenschaftlich-technische Fächer zu begeistern und insbesondere im regelrecht verhassten Physikunterricht flow-Erleben zu erzeugen. Im Rahmen dieser Arbeit wird das flow-Erleben von Studierenden in klassischen Laborexperimenten und FELS (Forschend-Entdeckendes Lernen mit dem Smartphone) als Lernumgebung untersucht. FELS ist eine an die Lebenswelt der Schüler*innen angepasste Lernumgebung, in der sie mit Smartphones ihre eigene Lebenswelt experimentell untersuchen. Es zeigt sich, dass sowohl klassische Laborexperimente als auch in der Lebenswelt durchgeführte, smartphonebasierte Experimente flow-Erleben erzeugen. Allerdings verursachen die smartphonebasierten Experimente kaum Stressgefühle. Die in dieser Arbeit herausgefundenen Ergebnisse liefern einen ersten Ansatz, der durch Folgestudien erweitert werden sollte. N2 - The present work examines to what extent physical experiments induce a flow-experience in students. Experiencing flow is seen as a source of motivation and should represent the path to joy and happiness. In particular, because of the often-cited shortage of employees in the natural sciences and technical professions, increasing motivation in natural sciences subjects is important. Because despite performance increases in international comparative tests, significantly fewer students in Germany want to take up such a profession than in other industrialized countries. It is therefore important to get students enthusiastic about scientific and technical subjects as early as possible and, in particular, to create a flow experience in the downright hated physics class. In the context of this work, the flow-experience of students is examined as a learning environment in classic laboratory experiments and FELS (inquiry-based learning with the smartphone, based on the German term: Forschend-Entdeckendes Lernen mit dem Smartphone). FELS is a learning environment adapted to the students' living environment, in which they use smartphones to experimentally examine their own living environment. It turns out that both classic laboratory experiments and smartphone-based experiments create flow-experiences. However, the smartphone-based experiments hardly cause any feelings of stress. The results found in this work provide a first approach, which should be expanded through follow-up studies.

While envy has been considered a status-related emotion and is likely to be experienced in response to perceiving another’s higher status, there is a lack of research exploring how status perceptions influence the emergence of envy on SNSs. This is important because SNSs typically quantify social interactions and reach with metrics that indicate users’ relative rank and status in the network. To understand how status perceptions impact SNS users, we introduce a new form of metric-based digital status rooted in SNS metrics that are available and visible on a platform. Drawing on social comparison theory and status literature, we conducted an online experiment to investigate how different forms of status contribute to the proliferation of envy on SNSs. Our findings shed light on how metric-based digital status influences feelings of envy on SNSs. Specifically, we could show that metric-based digital status impacts envy through increasing perceptions of others’ socioeconomic and sociometric statuses. Our study contributes to the growing discourse on the negative outcomes associated with SNS use and its consequences for users and society.

We extend these studies through a design that distinguishes between innocuous communication and communication about a cartel, sanctioning only the latter. To this aim, we introduce a participant in the role of the competition authority, who is properly incentivized to judge communication content and price setting behavior of the firms. Using this novel design, we revisit the question whether a leniency rule successfully destabilizes cartels. In contrast to existing experimental studies, we find that a leniency rule does not affect cartelization. We discuss potential explanations for this contrasting result.

We study one particular context in which ignorance can be beneficial: iterated strategic interactions in which voluntary cooperation may be sustained into the final round if players voluntarily forego knowledge about the time horizon. We experimentally examine this option to remain ignorant about the time horizon in a finitely repeated two-person prisoners’ dilemma game. We confirm that pairs without horizon knowledge avoid the drop in cooperation that otherwise occurs toward the end of the game. However, this effect is superposed by cooperation declining more rapidly in pairs without horizon knowledge during the middle phase of the game, especially if players do not know that the other player also wanted to remain ignorant of the time horizon.

Relatives, spouses, and friends are modestly to moderately similar in various characteristics, e.g., personality characteristics, interests, appearance. The role of psychological (e.g., skills, global appraisal) and social (e.g., gender, familial status) similarities in personal relationships and the association with relationship quality (emotional closeness and reciprocity of support) were examined in four independent studies. Young adults (N = 456; M = 27 years) and middle-aged couples from four different family types (N = 171 couples, M = 38 years) gave answer to a computer-aided questionnaire regarding their ego-centered networks. A subsample of 175 middle-aged adults (77 couples and 21 individuals) participated in a one-year follow-up questioning. Two experimental studies (N = 470; N = 802), both including two assessments with an interval of five weeks, were conducted to examine causal relationships among similarity, closeness, and reciprocity expectations. Results underline the role of psychological and social similarities as covariates of emotional closeness and reciprocity of support on the between-relationship level, but indicate a relatively weak effect within established relationships. In specific relationships, such as parent-child relationships and friendships, psychological similarity partly alleviates the effects of missing genetic relatedness. Individual differences moderate these between-relationship effects. In all, results combine evolutionary and social psychological perspectives on similarity in personal relationships and extend previous findings by means of a network approach and an experimental manipulation of existing relationships. The findings further show that psychological and social similarity have different implications for the study of personal relationships depending on the phase in the developmental process of relationships. N2 - Verwandte, Partner und Freunde ähneln sich in einer Vielzahl von Merkmalen wie z.B. Persönlichkeitseigenschaften, Einstellungen oder Aussehen. Die Bedeutung von Ähnlichkeit in psychologischen und demografischen Eigenschaften von Beziehungspartnern und die Zusammenhänge mit der Qualität der Beziehung wurden in vier unabhängigen Studien untersucht. Junge Erwachsene (N = 456; M = 27 Jahre) und Paare aus vier verschiedenen Familienformen (N = 171 Paare, M = 38 Jahre) beurteilten in einem PC-gestützten Fragebogen die sozialen Beziehungen in ihrem ego-zentrierten Netzwerk hinsichtlich wahrgenommener Ähnlichkeit, emotionaler Nähe und Reziprozität der Unterstützung. Ein Teil der Paare (77 Paare und 21 Einzelpersonen) nahm an der Ein-Jahres-Längsschnittstudie teil. In zwei Experimenten (N = 470; N = 802) wurde die Wahrnehmung von Ähnlichkeit manipuliert, um die Kausalwirkung auf die emotionale Nähe und die Erwartung von reziprokem Verhalten in Beziehungen zu prüfen. Die Studien zeigten, dass innerhalb eines sozialen Netzwerkes ähnliche Beziehungspartner auch emotional näher beurteilt wurden, es jedoch kaum wechselseitige Beeinflussungen innerhalb bestehender Beziehungen gab. In spezifischen Beziehungen, wie Eltern-Kind- oder Freundschaftsbeziehungen, konnte psychologische Ähnlichkeit den Effekt der fehlenden genetischen Verwandtschaft teilweise aufheben. Merkmale der Person moderierten diese Zusammenhänge auf der Beziehungsebene. Die Ergebnisse verknüpfen die evolutionspsychologische und die sozialpsychologische Perspektive der Ähnlichkeitsforschung und ergänzen bisherige Befunde durch den Einsatz des Sozialen Netzwerkansatzes und der experimentellen Manipulation von bestehenden Beziehungen. Zudem zeigen die Befunde, dass psychologische und demografische Ähnlichkeit unterschiedliche Implikationen für die Beziehungsforschung haben, in Abhängigkeit von der Entwicklungsphase der Beziehung.

As a basis, learning and forgetting mechanisms need to be understood in order to guide a change process efficiently and successfully. Our research aims to get a better understanding of individual differences and mechanisms in the change context by performing an experiment where individuals learn and later re-learn a complex production process using a simulation setting. The individual’s performance, as well as retentivity and prior knowledge is assessed. Our results show that higher retentivity goes along with better learning and forgetting performances. Prior knowledge did not reveal such relation to the learning and forgetting performances. The influence of age and gender is discussed in detail.

Since the number of knowledge-intensive processes is increasing more and more nowadays, the efficient design of knowledge transfers at business processes as well as the target-oriented improvement of them is essential, so that process outcomes satisfy high quality criteria and economic requirements. This particularly challenges knowledge management, aiming for the assignment of ideal manifestations of influence factors on knowledge transfers to a certain task. Faced with first attempts of knowledge transfer-based process improvements [1], this paper continues research about the quantitative examination of knowledge transfers and presents a ready-to-go experiment design that is able to examine quality of knowledge transfers empirically and is suitable to examine knowledge transfers on a quantitative level. Its use is proven by the example of four influence factors, which namely are stickiness, complexity, competence and time pressure.
