Based on dual process models of information processing, the present research addressed how explicit disgust sensitivity is re-adapted according to implicit disgust sensitivity via self-perception of automatic behavioral cues. Contrary to preceding studies (Hofmann, Gschwendner, & Schmitt, 2009) that concluded that there was a "blind spot" for self- but not for observer perception of automatic behavioral cues, in the present research, a re-adaption process was found for self-perceivers and observers. In Study 1 (N = 75), the predictive validity of an indirect disgust sensitivity measure was tested with a double-dissociation strategy. Study 2 (N = 117) reinvestigated the hypothesis that self-perception of automatic behavioral cues, predicted by an indirect disgust sensitivity measure, led to a re-adaption of explicit disgust sensitivity measures. Using a different approach from Hofmann et al. (2009), the self-perception procedure was modified by (a) feeding back the behavior several times while a small number of cues had to be rated for each feedback condition, (b) using disgust sensitivity as a domain with clearly unequivocal cues of automatic behavior (facial expression, body movements) and describing these cues unambiguously, and (c) using a specific explicit disgust sensitivity measure in addition to a general explicit disgust sensitivity measure. In Study 3 (N = 130), the findings of Study 2 were replicated and display rules and need for closure as moderator effects of predictive validity and cue utilization were additionally investigated. The moderator effects give hints that both displaying a disgusted facial expression and self-perception of one- own disgusted facial expression are subject to a self-serving bias, indicating that facial expression may not be an automatic behavior. Practical implications and implications for future research are discussed.
Student misbehavior and its treatment is a major challenge for teachers and a threat to their well-being. Indeed, teachers are obliged to punish student misbehavior on a regular basis. Additionally, teachers’ punishment decisions are among the most frequently reported situations when it comes to students’ experiences of injustice in school. By implication, it is crucial to understand teachers’ treatment of student misbehavior vis-à-vis students’ perceptions. One key dimension of punishment behavior reflects its underlying motivation and goals. People generally intend to achieve three goals when punishing misbehavior, namely, retribution (i.e., evening out the harm caused), special prevention (i.e., preventing recidivism of the offender), and general prevention (i.e., preventing imitation of others). Importantly, people’s support of these punishment goals is subject to hierarchy and power, implying that teachers’ and students’ punishment goal preferences differ. In this dissertation, I present three research projects that shed first light on teachers’ punishment and its goals along with the students’ perception of classroom intervention strategies pursuing these goals. More specifically, I first examined students’ (i.e., children’s) general support of each of the three punishment goals sketched above. Furthermore, I applied an attributional approach to understand and study the goals teachers intend to achieve when punishing student misbehavior. Finally, I investigated teachers’ and students’ support of the punishment goals regarding the same student misbehavior to directly compare their views on these goals and reactions pursuing them. In sum, the findings show that students generally prefer retribution and special prevention to general prevention, whereas teachers prefer general prevention and special prevention to retribution. This ultimately translates into a "mismatch" of teachers and students in their preferences for specific punishment goals, and the findings suggest that this may indeed enhance students’ perception of injustice. Overall, the results of the present research program may be valuable for the development of classroom intervention strategies that may reduce rather than enhance conflicts in student-teacher-interactions.
English prepositions take only a small proportion of the language but play a substantial role. Although prepositions are of course also frequently used in English textbooks for secondary school, students fail to incidentally acquire them and often show low achievements in using prepositions correctly. The strategy commonly employed by language instructors is teaching the multiple senses of prepositions by rote which fails to help the students to draw links between the different meanings in usage. New findings in Cognitive Linguistics (CL) suggest a different approach to teaching prepositions and thus might have a strong impact on the methodologies of foreign language teaching and learning on the aspects of meaningful learning. Based on the Theory of Domains (Langacker, 1987), the notions of image schemas (Johnson, 1987) as well as the Conceptual Metaphor Theory (Lakoff & Johnson, 1980), the present study developed a CL-inspired approach to teaching prepositions, which was compared to the traditional teaching method by an empirical study conducted in a German school setting. Referring to the participants from the higher track and the medium track, who are at different proficiency levels, the results indicate that the CL-inspired teaching approach improved students" performance significantly more than the traditional approach in all the cases for the higher track and in some cases for the medium track. Thus, these findings open up a new perspective of the CL-inspired meaningful learning approach on language teaching. In addition, the CL-inspired approach demonstrates the unification of the integrated model of text and picture comprehension (the ITPC model) in integrating the new knowledge with related prior knowledge in the cognitive structure. According to the learning procedure of the ITPC model, the image schema as visual image is first perceived through the sensory register, then is processed in the working memory by conceptual metaphor, and finally it is integrated with cognitive schemata in the long term memory. Moreover, deep-seated factors, such as transfer of mother tongue, the difficulty of teaching materials, and the influence of prior knowledge, have strong effects on the acquisition of English prepositions.
Audiences' movie evaluations have often been explored as effects of experiencing movies. However, little attention has been paid to the evaluative process itself and its determinants before, during, and after movie exposure. Moreover, until recently, research on the subjective assessment of specific film features (e.g., story, photography) has played a less important role. Adding to this research, this dissertation introduces the idea of subjective movie evaluation criteria (SMEC) and describes the scale construction for their measurement and its validation process. Drawing on social cognition theories, SMEC can be defined as standards that viewers use for assessing the features of films and conceptualized as mental representations of - or attitudes towards - specific movie features guiding cognitive and affective information processing of movies and corresponding evaluative responses. Studies were conducted in five phases to develop and validate scales for measuring and examining the structure of SMEC. In Phase I, open-ended data were categorized and content validated via a modified structure formation technique and items were developed. Subsequently in Phase II, participants completed an online questionnaire including revised and pilot-tested items. Exploratory factor analyses were iteratively applied to explore the latent structure and to select items. The resulting 8-factor model was cross-validated with different samples in Phase III applying confirmatory factor analyses which yielded good fit indices, thereby supporting structural validity. In Phase IV, latent state"trait analyses were carried out to examine the reliability, occasion specificity, common consistency, and method specificity of the eight dimensions. All factors - Story Verisimilitude, Story Innovation, Cinematography, Special Effects, Recommendation, Innocuousness, Light-heartedness, and Cognitive Stimulation - are reliable and are largely determined by stable individual differences, albeit some of them also show substantial systematic, but unstable effects due to the situation or interaction. These results provide evidence for the substantive validity of the SMEC scales. Finally, in Phase V the nomological network of SMEC was explored (external validity by examining correlations with related constructs like film genre preferences and personality traits). Taken together, whereas the SMEC concept - compatible with contemporary social cognition theories - provides a framework to theorize and address research questions about the role of movie evaluation criteria and evaluative processes, the SMEC scales are the proper tool for investigating the role of these criteria and the processes they are involved in.
Schizophrenia is a chronic mental health disorder, which changes rapidly the life of the persons and their families, who suffer from it. It causes high biological and psychological vulnerability as well as cognitive, emotional and behavioral disorders. Nowadays, evidence-based pharmacotherapy and psychotherapy are available aiming the rehabilitation and recovery of individuals with schizophrenia. A democratic society is obliged to give these people the opportunity to have an access to those treatments.
The following three published studies present this dissertation thesis and have a common focus on the implementation of evidence-based psychotherapy in individuals with schizophrenia.
The first study evaluates the efficacy of the Integrated Psychological Therapy (IPT) in Greece, one of the most evaluated rehabilitation programs. IPT was compared to
Treatment as Usual (TAU) in a randomized controlled trial (RCT) with 48 individuals with schizophrenia. Significant effects favouring IPT were found in working memory,
in social perception, in negative symptoms, in general psychopathology and in insight. This study supports evidence for the efficacy of IPT in Greece.
The second study evaluates a second hypothesis, when IPT is more and less effective regarding treatment resistant schizophrenia (TRS) and non treatment resistant
schizophrenia (NTRS). It is a part of the first paper. Significant effects favouring NTRS were found for verbal memory, for symptoms, for functioning and quality of
life. Effect sizes showed superiority of NTRS in comparison to TRS. IPTTRS showed on the other side some significant improvements. This study presents the initial findings of a larger study to be conducted internationally for the first time.
The third study is a systematic review, which aims to evaluate the efficacy of Cognitive Behavioral Therapy (CBT), of Meta Cognitive Therapy (MCT), Metacognitive Training (MCTR), Metacognitive Reflection and Insight Therapy
(MERIT), of various Rehabilitation Programs and Recovery Programs in individuals with schizophrenia. 41 RCTs and 12 Case Studies were included. The above interventions are efficacious in the improvement of cognitions, symptoms, functional outcome, insight, self-esteem, comorbid disorders and metacognitive capacity.
The three studies provide insight regarding the importance of evidence-based psychotherapy in persons with schizophrenia leading to recovery and reintegration into
society. Future RCTs with larger samples and long-term follow up, combining evidence-based psychotherapies for individuals with schizophrenia need to be done.
Science education has been facing important challenges in the recent years: the decline in student’s interest in scientific topics, and moreover, the decrease of students pursuing science beyond their compulsory studies (Bennett, Hogarth, Lubben, 2003). As a result, research has focus on examining different approaches that could attempt to improve the situation. One of these approaches has been the use of context-based problem-solving tasks (Kölbach & Sumfleth, 2011; Bennett, Hogarth, Lubben, 2003). While research into context-based problem-solving tasks suggest that they are very motivating for students, it is still unclear how they influence motivation. Following an experimental pretest-postest design, two studies examined the effects of context-based task characteristics of contextualization, complexity, and transparency, on students’ motivational variables, performance, and metacognitive experiences.
Results from both studies suggest that the task characteristic of contextualization directly influences how students’ interest is triggered and maintained throughout the task. On the other hand, the task characteristics of complexity and transparency had different effects for the other dependent variables of effort, difficulty, and solution correctness.
Moreover, data shows that other motivational variables such as anxiety and success expectancies are strongly influenced by the interaction of the parameters under study. The dissertation concludes that appropriate design and use of context-based task characteristics can benefit students’ learning processes and outcomes.
Harvesting Season?
(2022)
Efforts to induce customers to buy groceries through the Internet have existed for around twenty years. Early on, the market structures of the digital grocery trade were still strongly fragmented and poorly coordinated. Due to the technological advancement in the past decade, the digital purchase of groceries has become more attractive. The adoption rate of these services varies greatly between different regions. In Germany in particular, the digital grocery trade is stagnating at a comparatively low level. In this regard, this dissertation analyzes both the retail-side market structures and the expectations and obstacles of German consumers.
The year 2020 connotes a turning point for the online grocery trade, as daily routines such as grocery shopping were subject to strict regulations imparted at a governmental level in order to reduce COVID-19 infections. At the same time, despite this opportunity, the digital grocery trade has not yet established itself nationwide in Germany. This can be attributed to a lack of investments, but also to inadequate digitization measures. A stronger synchronization between the digital and stationary offer, better integration of digital food services at a regional level as well as adapted, target group-appropriate digital solutions for the efficient breakdown of usage barriers will benefit service usage. The importance of stable food chains and distribution channels was illustrated by the COVID-19 pandemic. Further research should help to develop the digital food trade into a stable and sustainable supplementation of the stationary store.
Emotion regulation – an empirical investigation in female adolescents with nonsuicidal self- injury
(2015)
Nonsuicidal self-injury (NSSI) was included as a condition for further study in the DSM-5. Therefore, it is necessary to investigate the suggested diagnostic criteria and the clinical and psychological correlates. In order to provide an optimal treatment best tailored to the patients need, a clear differentiation between Borderline Personality Disorder (BPD) and NSSI is needed. The investigation of personality traits specific to patients with NSSI might be helpful for this differentiation. Furthermore, social difficulties can often be a trigger for NSSI. However, little is known about how adolescents with NSSI perceive social situations. Therefore, we examined how adolescents with NSSI process emotional expressions. A new emotion recognition paradigm (ERP) using colored and morphed facial expressions of happiness, anger, sadness, disgust and fear was developed and evaluated in a student sample, selected for being high (HSA) or low socially anxious (LSA). HSA showed a tendency towards impaired emotion recognition, and the paradigm demonstrated good construct validity.
For the main study, we investigated characteristics of NSSI, clinical and psychological correlates, personality traits and emotion recognition. We examined 57 adolescents with NSSI diagnosis, 12 adolescents with NSSI without impairment/distress and 14 adolescents with BPD, 32 clinical controls without NSSI, and 64 nonclinical controls. Participants were interviewed regarding mental disorders, filled out self-report questionnaires and participated in the ERP.
Results indicate that adolescents with NSSI experienced a higher level of impairment than clinical controls. There were similarities between adolescents with NSSI and adolescents with BPD, but also important differences. Adolescents with NSSI were characterized by specific personality traits such as high harm avoidance and novelty seeking compared to clinical controls. In adolescents with BPD, these personality traits were even more pronounced. No group differences in the recognition of facial expressions were found. Nonetheless compared to the control group, adolescents with NSSI rated the stimuli as significantly more unpleasant and arousing.
In conclusion, NSSI is a highly impairing disorder characterized by high comorbidity with various disorders and by specific personality traits, providing further evidence that NSSI should be handled as a distinct diagnostic entity. Consequently, the proposed DSM-5 diagnostic criteria for NSSI are useful and necessary.
Previous research revealed that teachers hold beliefs about gifted students combining high intellectual ability with deficits in non-cognitive domains, outlined in the so-called disharmony hypothesis. Since teachers’ beliefs about giftedness can influence which students they identify as gifted, the empirical investigation of beliefs is of great practical relevance. This dissertation comprises three research articles that investigated teacher beliefs about gifted students’ characteristics in samples of pre-service teachers using an experimental vignette approach. Chapter I starts with a general introduction into beliefs, and presents the research aims of the present dissertation. The first article (Chapter II) focused on the interaction of beliefs about giftedness and gender in a sample of Australian pre-service teachers and tested if social desirability occurred when using the vignette design. Beside evidence for beliefs in line with the disharmony hypothesis, results revealed typical gender stereotypes. However, beliefs about giftedness appeared not to be gender specific and thus, to be similar for gifted girls and boys. The vignette approach was found to be an adequate design for assessing teacher beliefs. The second article (Chapter III) investigated teacher beliefs and their relationship to motivational orientations for teaching gifted students in a cross-country sample of German and Australian pre-service teachers. Motivational orientations comprise cognitive components (self-efficacy) and affective components (enthusiasm). Findings revealed beliefs in the sense of the disharmony hypothesis for pre-service teachers from both countries. Giftedness when paired with beliefs about high maladjustment was found to be negatively related to teachers’ self-efficacy for teaching gifted students. The third article (Chapter IV) examined the role of teachers’ belief in a just world for the formation of beliefs using a sample of Belgian pre-service teachers. It was found that the stronger pre-service teachers’ belief in a just world was, the more they perceived gifted students’ high intellectual ability as unfair and thus, neutralized that injustice by de-evaluating students’ non-cognitive abilities. In a general discussion (Chapter V), findings of the three articles are combined and reflected. Taken together, the present dissertation showed that teacher beliefs about gifted students’ characteristics are not gender specific, generalizable over countries, negatively related to teacher motivation and can be driven by fairness beliefs.
The aim of this dissertational work was to examine physiological (heart rate variability measures) and biomechanical parameters (step features) as possible anticipating indicators of psychological mood states. 420 participants (275 male and 145 female, age: M=34.7 years ± 9.7) engaged in a 60-minute slow endurance run while they were asked questions via a mobile answering and recording device. We measured several mood states, physiological measures, and biomechanical parameters. We used a latent growth curve analysis to examine the cross-lagged effects. Results demonstrated significant (p ≤.05) relationships between biomechanical shoe features anticipating psychological mood states, as well as psychological mood states anticipating physiological parameters.
