In two studies, the aim of this research was to develop and validate a Polish version of the reduced Discounting Inventory. In Study 1 (N = 623) items extraction from the 48-item DI was based upon item-total correlation and items with highest coefficients were considered. The reduced Discounting Inventory resulted in sixteen items. Cronbach's a coefficient was .78, and the item-total correlations ranged between .59 and .77. The correlation between Polish versions of reduced Discounting Inventory and longer 48-item Discounting Inventory was .85. Next, the reduced Discounting Inventory was evaluated in terms of factorial and construct validity. The structure of the instrument was analysed by Confirmatory Factor Analyses procedure. It indicated that the four-factor structure had the best fit to the data. Additionally, we show that this reduced Discounting Inventory closely parallels the longer 48-item inventory its relation to traditional discounting measures using pairs of hypothetical choices (expect for the delay discounting subscale). Finally, in study 2, the test-retest reliability of the reduced Discounting Inventory over a 3-month interval was assessed (247 subjects of the 623 individuals who participated in Study 1). Results indicated good stability of the reduced measure (>= .88). It is concluded that the reduced Discounting Inventory has notable psychometric properties and that it can serve as an alternative measure of discounting when situations do not allow the use of longer inventories.
Implementing innovation laboratories to leverage intrapreneurship are an increasingly popular organizational practice. A typical feature in these creative environments are semi-autonomous teams in which multiple members collectively exert leadership influence, thereby challenging traditional command-and-control conceptions of leadership. An extensive body of research on the team-centric concept of shared leadership has recognized the potential for pluralized leadership structures in enhancing team effectiveness; however, little empirical work has been conducted in organizational contexts in which creativity is key. This study set out to explore antecedents of shared leadership and its influence on team creativity in an innovation lab. Building on extant shared leadership and innovation research, we propose antecedents customary to creative teamwork, that is, experimental culture, task reflexivity, and voice. Multisource data were collected from 104 team members and 49 evaluations of 29 coaches nested in 21 teams working in a prototypical innovation lab. We identify factors specific to creative teamwork that facilitate the emergence of shared leadership by providing room for experimentation, encouraging team members to speak up in the creative process, and cultivating a reflective application of entrepreneurial thinking. We provide specific exemplary activities for innovation lab teams to increase levels of shared leadership.
In modern times of evolving globalization and continuous technological developments, organizations are required to respond to ever-changing demands. Therefore, to be successful in today’s highly uncertain environments, organizations need employees to actively search for opportunities, anticipate challenges, and act ahead. In other words, employee proactivity in the workplace represents a highly valuable resource in nowadays organizations. Empirical studies conducted as part of this thesis advance the research on the outcomes of proactivity from the individual perspective. The main contribution of this thesis pertains to revealing several important individual and contextual conditions under which engaging in proactivity will have negative and positive effects on employees’ well-being and their consequent behaviours, as well as shedding light on the unique psychological mechanisms through which these effects unfold. From a practical standpoint, this research underscores the importance of creating work environments that support employees’ autonomous motivation for proactivity and urge organizations and managers to be mindful about the pressures they place on employees to be proactive at work. Besides, this thesis stimulates research efforts aimed at further extending our knowledge of when and how individual proactive behaviours at work will do more good than harm for those who enact them.
Interoception is an often neglected but crucial aspect of the human minimal self. In this perspective, we extend the embodiment account of interoceptive inference to explain the development of the minimal self in humans. To do so, we first provide a comparative overview of the central accounts addressing the link between interoception and the minimal self. Grounding our arguments on the embodiment framework, we propose a bidirectional relationship between motor and interoceptive states, which jointly contribute to the development of the minimal self. We present empirical findings on interoception in development and discuss the role of interoception in the development of the minimal self. Moreover, we make theoretical predictions that can be tested in future experiments. Our goal is to provide a comprehensive view on the mechanisms underlying the minimal self by explaining the role of interoception in the development of the minimal self.
The functional significance of the N400 evoked-response component is still actively debated. An increasing amount of theoretical and computational modelling work is built on the interpretation of the N400 as a prediction error. In neural network modelling work, it was proposed that the N400 component can be interpreted as the change in a probabilistic representation of meaning that drives the continuous adaptation of an internal model of the statistics of the environment. These results imply that increased N400 amplitudes should correspond to greater adaptation, which can be measured via implicit memory. To investigate this model derived hypothesis, the current study manipulated expectancy in a sentence reading task to influence N400 amplitudes and subsequently presented the previously expected vs. unexpected words in a perceptual identification task to measure implicit memory. As predicted, reaction times in the perceptual identification task were significantly faster for previously unexpected words that induced larger N400 amplitudes in the previous sentence reading task. Additionally, it could be demonstrated that this adaptation seems to specifically depend on the process underlying N400 amplitudes, as participants with larger N400 differences during sentence reading also exhibited a larger implicit memory benefit in the perceptual identification task. These findings support the interpretation of the N400 as an implicit learning signal driving adaptation in language processing.
Background and Aims: Ostarek et al. (2019) claimed a conclusive
demonstration that language comprehension relies profoundly on
visual simulations. They presented participants with visual noise during sentence-picture verification (SPV) and measured lateralized button response speed. The authors selectively eliminated the classical congruency effect (faster yes decisions when pictures match the objects implied by the sentences) with ‘‘high level’’ noise made from images of other objects. However, that visual noise included tool pictures, known to activate lateralized motor affordances. Moreover, some of their sentences described motor actions. This raises the question whether motor simulation may have contaminated their results.
Methods: Replicating Ostarek et al. (2019), 33 right-handed
participants performed SPV but either without visual noise or while viewing (a) only left-handled or (b) only right-handled or (c) alternatingly left- and right-handled tools. Accuracy and reaction times of manual yes responses were analyzed. Additionally, hand-relatedness of sentences was rated.
Results: Replicating Ostarek et al. (2019), the classical SPV congruency effect appeared without noise and vanished when alternatingly handled tools were presented. Crucially, it reappeared when noise objects were consistently either left- or righthandled. Higher hand-relatedness of sentence content reduced SPV performance and accuracy was lower with right-handled noise.
Conclusion: First, we demonstrated an interaction between motor-
related language, visual affordances and motor responses in SPV.
This result supports the embodied view of language processing.
Second, we identified a motor process not previously known in SPV. This extends our understanding of mental simulation and calls for methodological controls in future studies.
Seit dem 01. 04. 2017 erfolgte eine umfangreiche Reform der Psychotherapie-Richtlinie. Neben der Einführung neuer Leistungen (z. B. Akutbehandlung, psychotherapeutische Sprechstunde) wurden auch Änderungen im Ablauf und der Beantragung von Psychotherapie beschlossen. Beispielsweise ist der Bericht an den Gutachter bzw. die Gutachterin seltener eine notwendige Voraussetzung zur Durchführung einer psychotherapeutischen Behandlung, als dass zuvor der Fall war. Im Zuge der Reform wurde auch der Leitfaden für die Gestaltung des Berichts an den Gutachter bzw. die Gutachterin überarbeitet.
Vor dem Hintergrund der Psychotherapie-Richtlinien-Reform ist das Werk „Leitfaden für den VT-Bericht an den Gutachter“ von Daniel Surall und Oliver Kunz sehr willkommen. Das Buch gliedert sich insgesamt in zehn Kapitel, in denen die Autoren ausführlich auf den reformierten Bericht an den Gutachter bzw. an die Gutachterin eingehen. In den ersten beiden Kapiteln fassen die Autoren die Änderungen zur Psychotherapie-Richtlinie und im Bericht an den Gutachter / die Gutachterin zusammen. In den folgenden sechs Kapiteln wird auf die einzelnen Abschnitte des neuen Berichts an den Gutachter/die Gutachterin eingegangen. Sehr hilfreich ist hierbei, dass die Autoren zahlreiche Fallbeispiele nutzen, um die einzelnen Abschnitte des Berichts an den Gutachter/die Gutachterin zu erläutern. Auch die übersichtliche Darstellungsform in Form von Tabellen (z. B. zur Darstellung der Verhaltensanalyse) erleichtert den Leser_innen die Nachvollziehbarkeit der Inhalte. Erfreulich ist auch, dass die Autoren hinsichtlich der Antragstellung auch immer auf Unterschiede zwischen erwachsenen Patient_innen und Kindern und Jugendlichen eingehen. Im neunten Kapitel des Leitfadens wird ausführlicher das Thema Umwandlungs- und Fortführungsanträge aufgegriffen. Dies ist insbesondere sinnvoll, da nach der neuen Psychotherapie-Richtlinie für Kurzzeitanträge in der Regel keine Berichtspflicht besteht und Umwandlungs- und Fortführungsanträge in der Praxis häufiger als zuvor von Relevanz sein dürften. Im zehnten Kapitel wird in knapper Weise darauf eingegangen, wie bei Ablehnung oder Kürzung von beantragten Leistungen vorgegangen werden kann.
Das Buch umfasst einen umfangreichen Anhang (67 Seiten), in dem Beispiele für Berichte an den Gutachter / die Gutachterin und Behandlungspläne für verschiedene psychische Störungen zu finden sind. Auch hierbei werden sowohl Berichte für Erwachsene als auch für Kinder und Jugendliche präsentiert. Zudem beinhaltet der Anhang des Buches das Berner Inventar für Therapieziele, Auszüge aus dem AMDP-Befundbogen (Arbeitsgemeinschaft Methodik und Dokumentation in der Psychiatrie, 2018)<\litr>, den Leitfaden zum Erstellen des Berichts an die Gutachter_innen (PTV 3) sowie einer Gegenüberstellung des alten und des neuen Leitfadens für den Bericht an die Gutachter_innen.
Bei dem von Surall und Kunz vorgelegten Buch handelt es sich um einen äußerst hilfreichen Leitfaden, der Therapeut:innen bei der Abfassung des Berichts an den Gutachter / die Gutachterin im Rahmen der Verhaltenstherapie unterstützen kann. Hierbei kann der Leitfaden Psychotherapeut_innen in Ausbildung bei der Abfassung ihrer ersten Anträge unterstützen. Aber auch erfahrenen Kolleg_innen können bei dem Übergang in die neuen Antragsformalitäten, die mit der Reform der Psychotherapie-Richtlinie einhergingen, unterstützen werden. Hierbei ist insbesondere die Im Anhang befindliche Gegenüberstellung des alten und des neuen Leitfadens für den Bericht an den Gutachter / die Gutachterin hilfreich, um sich einen schnellen Überblick über die Änderungen zu verschaffen. Insgesamt werden die einzelnen Abschnitte des Berichts an den Gutachter / die Gutachterin sehr gut strukturiert und verständlich erläutert. Die vielen Beispiele und die ausführlichen Materialien im Anhang ergänzen zudem die Erläuterungen und erleichtern das Verständnis. Zu Beginn des Buches wäre zudem noch eine Abbildung hilfreich gewesen, die den Ablauf der Beantragung von Psychotherapie schematisch darstellt, um einen genaueren Überblick über die Beantragung von Psychotherapie nach der neuen Psychotherapie-Richtlinie zu erhalten. Auch ein Stichwortverzeichnis würde die Suche nach bestimmten Inhalten erleichtern.
Zusammenfassend kann festgehalten werden, dass es sich bei dem Werk von Surall und Kunz um einen sehr empfehlenswerten Leitfaden handelt, der im Rahmen der Antragstellung von Verhaltenstherapie genutzt werden kann. Aufgrund der klaren Struktur und Anschaulichkeit durch viele Beispielanträge bringt das Buch alle Voraussetzungen mit, um sich als Standartwerk zu etablieren, dass Therapeut_innen bei der Beantragung von Verhaltenstherapie in äußerst hilfreicher Weise unterstützt.
This study investigated how touching and being touched by a humanoid robot affects human physiology, impressions of the interaction, and attitudes towards humanoid robots. 21 healthy adult participants completed a 3 (touch style: touching, being touched, pointing) x 2 (body part: hand vs buttock) within-subject design using a Pepper robot. Skin conductance response (SCR) was measured during each interaction. Perceived impressions of the interaction (i.e., friendliness, comfort, arousal) were measured per questionnaire after each interaction. Participants' demographics and their attitude towards robots were also considered. We found shorter SCR rise times in the being touched compared to the touching condition, possibly reflecting psychological alertness to the unpredictability of robot-initiated contacts. The hand condition had shorter rise times than the buttock condition. Most participants evaluated the hand condition as most friendly and comfortable and the robot-initiated interactions as most arousing. Interacting with Pepper improved attitudes towards robots. Our findings require future studies with larger samples and improved procedures. They have implications for robot design in all domains involving tactile interactions, such as caring and intimacy.
Hintergrund
Essstörungen sind prävalent, chronifizieren häufig und gehen trotz wirksamer Behandlungsansätze oft mit Rückfällen einher. Prävention ist daher entscheidend, jedoch sind viele aktuelle Präventionsprogramme ressourcenintensiv. Internetbasierte Interventionen können eine kostengünstige und niedrigschwellige Alternative darstellen, sind jedoch bislang nur wenig untersucht.
Fragestellung
Wie wirksam ist ein internetbasiertes, unbegleitetes Präventionsangebot?
Material und Methode
Die Intervention wurde auf Basis verhaltenstherapeutischer Techniken neu entwickelt und im Rahmen eines randomisierten Wartekontrollgruppendesigns an 200 Studierenden pilotiert. Vor und nach der Intervention bzw. Wartezeit wurden Daten zu essstörungsspezifischer Pathologie (Eating Disorder Examination-Questionnaire, EDE‑Q), Wohlbefinden (WHO-Five Well-Being Index, WHO-5) sowie Selbstwert (Rosenberg Self-Esteem Scale, RSES) erhoben und varianzanalytisch untersucht.
Ergebnisse
Die Intervention wurde von 43 % der Teilnehmenden vollständig durchlaufen. Der Selbstwert nahm in der Interventionsgruppe im Vergleich zur Wartekontrollgruppe stärker zu (η2p= 0,33). Auf den anderen Variablen ergaben sich keine signifikanten Unterschiede zwischen den Gruppen.
Schlussfolgerung
Unbegleitete Online-Selbsthilfe erscheint vielversprechend, um den Selbstwert zu verbessern und damit einen Beitrag zur Prävention von Essstörungen zu leisten. Untersuchungen in größeren, heterogenen Gruppen sind künftig nötig, um ggf. vorhandene, kleinere Präventionseffekte zu entdecken.
Purpose:
Current research supports the effectiveness of mindfulness-based interventions for maladaptive eating behaviors associated with obesity and eating disorders. To investigate potential underlying mechanisms at work, reliable and valid instruments that allow for an exhaustive assessment of the context-specific construct Mindful Eating (ME) are needed. Therefore, the current work aimed to develop a comprehensive inventory reflecting a wide range of ME attitudes and behaviors: The Mindful Eating Inventory (MEI).
Methods & Results:
Study 1 describes the item pool development for an initial version of the MEI comprising various steps (compilation of items, expert ratings, focus groups and think aloud protocols by laypersons). Within Study 2, the factor structure of this initial version was explored in an online sample of N = 828 participants and the item pool was shortened via a sequential process based on statistical and content-related considerations. Exploratory factor analyses yielded a seven-factor structure. This structure could be confirmed within Study 3 on an independent online sample of N = 612 participants using confirmatory factor analysis. Criterion validity was supported by hypotheses-confirming correlations with eating-specific and global health-relevant outcomes.
Conclusion:
Our findings demonstrate that the MEI is a valid and reliable (in terms of internal consistency and retest-reliability) tool, which allows for a comprehensive assessment of various ME attitudes and behaviors within one parsimonious inventory. It further enabled us to propose a so far missing, initial scientific operational definition of this eating-specific construct, that may help to advance future research and clinical application by clarifying mechanisms of action.
The force of numbers
(2021)
The study has two objectives: (1) to introduce grip force recording as a new technique for studying embodied numerical processing; and (2) to demonstrate how three competing accounts of numerical magnitude representation can be tested by using this new technique: the Mental Number Line (MNL), A Theory of Magnitude (ATOM) and Embodied Cognition (finger counting-based) account. While 26 healthy adults processed visually presented single digits in a go/no-go n-back paradigm, their passive holding forces for two small sensors were recorded in both hands. Spontaneous and unconscious grip force changes related to number magnitude occurred in the left hand already 100-140 ms after stimulus presentation and continued systematically. Our results support a two-step model of number processing where an initial stage is related to the automatic activation of all stimulus properties whereas a later stage consists of deeper conscious processing of the stimulus. This interpretation generalizes previous work with linguistic stimuli and elaborates the timeline of embodied cognition. We hope that the use of grip force recording will advance the field of numerical cognition research.
Mental health problems are highly prevalent worldwide. Fortunately, psychotherapy has proven highly effective in the treatment of a number of mental health issues, such as depression and anxiety disorders. In contrast, psychotherapy training as is practised currently cannot be considered evidence-based. Thus, there is much room for improvement. The integration of simulated patients (SPs) into psychotherapy training and research is on the rise. SPs originate from the medical education and have, in a number of studies, been demonstrated to contribute to effective learning environments. Nevertheless, there has been voiced criticism regarding the authenticity of SP portrayals, but few studies have examined this to date.
Based on these considerations, this dissertation explores SPs’ authenticity while portraying a mental disorder, depression. Altogether, the present cumulative dissertation consists of three empirical papers. At the time of printing, Paper I and Paper III have been accepted for publication, and Paper II is under review after a minor revision.
First, Paper I develops and validates an observer-based rating-scale to assess SP authenticity in psychotherapeutic contexts. Based on the preliminary findings, it can be concluded that the Authenticity of Patient Demonstrations scale is a reliable and valid tool that can be used for recruiting, training, and evaluating the authenticity of SPs.
Second, Paper II tests whether student SPs are perceived as more authentic after they receive an in-depth role-script compared to those SPs who only receive basic information on the patient case. To test this assumption, a randomised controlled study design was implemented and the hypothesis could be confirmed. As a consequence, when engaging SPs, an in-depth role-script with details, e.g. on nonverbal behaviour and feelings of the patient, should be provided.
Third, Paper III demonstrates that psychotherapy trainees cannot distinguish between trained SPs and real patients and therefore suggests that, with proper training, SPs are a promising training method for psychotherapy.
Altogether, the dissertation shows that SPs can be trained to portray a depressive patient authentically and thus delivers promising evidence for the further dissemination of SPs.
Background
Despite the prevalence of obsessive-compulsive disorder (OCD), its precise identification remains challenging. With the Zohar-Fineberg Obsessive-Compulsive Screen (ZF-OCS; 5 or 6 items), a brief instrument is widely available mainly in English. As there is a lack of empirical studies on the ZF-OCS, the aim of the present study was to translate the items into German and investigate the instrument in a nonclinical sample.
Methods
In two consecutive online surveys, n = 304 and n = 51 students participated. Besides the ZF-OCS, they answered established measures on OCD, depression, health anxiety, general anxiety and health-related well-being.
Results
Whereas internal consistency was low (α = .53–.72; ω = .55–.69), retest reliability (rt1,t2 = .89) at two weeks was high. As expected, we found high correlations with other OCD instruments (r > .61; convergent validity), and significantly weaker correlations with measures of depression (r = .39), health anxiety (r = .29), and health-related well-being (r = −.28, divergent validity). Nonetheless, the correlations with general anxiety were somewhere in between (r = .52).
Conclusions
Due to heterogeneous OCD subtypes, the ZF-OCS asks diverse questions which probably resulted in the present internal consistency. Nevertheless, the results on retest reliability and validity were promising. As for other OCD instruments, divergent validity regarding general anxiety seems problematic to establish. Even so, the ZF-OCS seems valuable for screening purposes, as it is short and easy to administer, and may facilitate initiating subsequent clinical assessment. Further studies should determine the instrument’s diagnostic accuracy.

We describe a mathematically simple yet precise model of activation suppression that can explain the negative-going delta plots often observed in standard Simon tasks. The model postulates a race between the identification of the relevant stimulus attribute and the suppression of irrelevant location-based activation, with the irrelevant activation only having an effect if the irrelevant activation is still present at the moment when central processing of the relevant attribute starts. The model can be fitted by maximum likelihood to observed distributions of RTs in congruent and incongruent trials, and it provides good fits to two previously-reported data sets with plausible parameter values. R and MATLAB software for use with the model is provided.
Parents, peers, and teachers provide a powerful context for school students' well-being. However, a detailed and systematic analysis of how parental, peer, and teacher support relate to students' well-being, measured by the dimensions self-worth, psychological and physical well-being, is still missing. To address this research gap, the following study investigates 733 adolescent German students from grades 7 and 8 (M-age = 13.97, SD = 0.41, 52% girls) with respect to their perceived supportive relationships at home and within the school context. The study considers gender, socioeconomic status, and school form as potential confounders. The results of the structural equation model, analyzed with the statistical software R, indicate that perceived teacher support was positively related to students' self-worth and physical well-being, while peer support was related to psychological well-being. Students who perceived their parents as supportive reported higher well-being with respect to all three dimensions investigated.
