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.
Culture and violence
(2010)
The basic assumption of this study is that specific cultural conditions may lead to psychopathological reactions through which an increase in interpersonal violence may happen. The objective of this study was to define to what extent homicide rates across national cultures might be associated with the strength of their attitudes toward specific beliefs and values, and their scores in specific cultural dimensions. To answer this question, nine independent variables were defined six of which were related to the people- attitudes pertaining importance of religion (Religiosity), excessive feeling of choice and control (Omnipotence), clear-cut distinction between good and evil (Absolutism), proud of their nationality (Nationalism), approval of competition (Competitiveness), and high respect for authorities and emphasis on obedience (Authoritarianism). The data for these variables were collected from World Values Survey. For two cultural dimensions, Collectivism, and Power Distance, Hofstede- scores were used. The 9th variable was GNI per capita. After estimation of 7% missing values in the whole data through multiple imputation, a sample of 81 nations was used for further statistical analyses.
Results: Stepwise regression analysis indicated Omnipotence and GNI as the strongest predictors of homicide (β = .44 P = .000; β = -.27 P = .006 respectively). The 9 independent variables were loaded on two factors, socio-economic development (SED) and psycho-cultural factor (Psy-Cul), which were negatively correlated (-.47). The Psy-Cul was interpreted as an indicator of narcissism, and a mediator between SED and homicide. Hierarchical cluster analysis made a clear distinction among three main groups of Western, Developing, and post-Communist nations on the basis of the two factors.
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.
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.
Technical products have become more than practical tools to us. Mobile phones, for example, are a constant companion in daily life. Besides purely pragmatic tasks, they fulfill psychological needs such as relatedness, stimulation, competence, popularity, or security. Their potential for the mediation of positive experience makes interactive products a rich source of pleasure. Research acknowledged this: in parallel to the hedonic/utilitarian model in consumer research, Human-Computer Interaction (HCI) researchers broadened their focus from mere task-fulfillment (i.e., the pragmatic) to a holistic view, encompassing a product's ability for need-fulfillment and positive experience (i.e., the hedonic). Accordingly, many theoretical models of User Experience (UX) acknowledge both dimensions as equally important determinants of a product's appeal: pragmatic attributes (e.g., usability) as well as hedonic attributes (e.g., beauty). In choice situations, however, people often overemphasize the pragmatic, and fail to acknowledge the hedonic. This phenomenon may be explained by justification. Due to their need for justification, people attend to the justifiability of hedonic and pragmatic attributes rather than to their impact on experience. Given that pragmatic attributes directly contribute to task-fulfillment, they are far easier to justify than hedonic attributes. People may then choose the pragmatic over the hedonic, despite a true preference for the hedonic. This can be considered a dilemma, since people choose what is easy to justify and not what they enjoy the most. The present thesis presents a systematic exploration of the notion of a hedonic dilemma in the context of interactive products.
A first set of four studies explored the assumed phenomenon. Study 1 (N = 422) revealed a reluctance to pay for a hedonic attribute compared to a pragmatic attribute. Study 2 (N = 134) demonstrated that people (secretly) prefer a more hedonic product, but justify their choice by spurious pragmatic advantages. Study 3 (N = 118) confronted participants with a trade-off between hedonic and pragmatic quality. Even though the prospect of receiving a hedonic product was related to more positive affect, participants predominantly chose the pragmatic, especially those with a high need for justification. This correlation between product choice and perceived need for justification lent further support to the notion that justification lies at the heart of the dilemma. Study 4 (N = 125) explored affective consequences and justifications provided for hedonic and pragmatic choice. Data on positive affect suggested a true preference for the hedonic - even among those who chose the pragmatic product.
A second set of three studies tested different ways to reduce the dilemma by manipulating justification. Manipulations referred to the justifiability of attributes as well as the general need for justification. Study 5 (N = 129) enhanced the respective justifiability of hedonic and pragmatic choice by ambiguous product information, which could be interpreted according to latent preferences. As expected, enhanced justifiability led to an increase in hedonic but not in pragmatic choice. Study 6 (N = 178) manipulated the justifiability of hedonic choice through product information provided by a "test report", which suggested hedonic attributes as legitimate. Again, hedonic choice increased with increased justifiability. Study 7 (N = 133) reduced the general need for justification by framing a purchase as gratification. A significant positive effect of the gratification frame on purchase rates occurred for a hedonic but not for a pragmatic product.
Altogether, the present studies revealed a desire for hedonic attributes, even in interactive products, which often are still understood as purely pragmatic "tools". But precisely because of this predominance of pragmatic quality, people may hesitate to give in to their desire for hedonic quality in interactive products - at least, as long as they feel a need for justification. The present findings provide an enhanced understanding of the complex consequences of hedonic and pragmatic attributes, and indicate a general necessity to expand the scope of User Experience research to the moment of product choice. Limitations of the present studies, implications for future research as well as practical implications for design and marketing are discussed.
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.
The present thesis investigates attitudes and prosocial behavior between workgroups from a social identity and intergroup contact perspective. Based on the Common In-group Identity Model (CIIM; Gaertner & Dvoidio, 2000), it is hypothesized that "optimal" conditions for contact (Allport, 1954) create a common identity at the organizational level which motivates workgroups to cooperate and show organizational citizenship behavior (OCB) rather than intergroup bias. Predictions based on the CIIM are extended with hypotheses derived from the In-group Projection Model (IPM; Mummendey & Wenzel, 1999) and the Self-Categorization Model of Group Norms (Terry & Hogg, 1996). Hypotheses are tested with data from N1 = 281 employees of N2 = 49 different workgroups and their workgroup managers of a German mail-order company (Study 1). Results indicate that group- and individual-level contact conditions are predictive of lower levels of intergroup bias and higher levels of cooperation and helping behavior. A common in-group representation mediates the effect on out-group attitudes and intergroup cooperation. In addition, the effect of a common in-group representation on intergroup bias is moderated by relative prototypicality, as predicted by the IPM, and the effect of prosocial group norms on helping behavior is moderated by workgroup identification, as predicted by the Self-Categorization Model of Group Norms. A longitudinal study with Ntotal = 57 members of different student project groups replicates the finding that contact under "optimal" conditions reduces intergroup bias and increases prosocial behavior between organizational groups. However, a common in-group representation is not found to mediate this effect in Study 2. Initial findings also indicate that individual-level variables, such as helping behavior toward members of another workgroup, may be better accounted for by variables at the same level of categorization (cf. Haslam, 2004). Thus, contact in a context that makes personal identities of workgroup members salient (i.e., decategorization) may be more predictive of interpersonal prosocial behavior, while contact in a context that makes workgroup identities salient (i.e., categorization) may be more predictive of intergroup prosocial behavior (cf. Tajfel, 1978). Further data from Study 1 support such a context-specific effect of contact between workgroups on interpersonal and intergroup prosocial behavior, respectively. In the last step, a temporal integration of the contact contexts that either lead to decategorization, categorization, or recategorization are examined based on the Longitudinal Contact Model (Pettigrew, 1998). A first indication that a temporal sequence from decategorization via categorization to recategorization may be particularly effective in fostering intergroup cooperation is obtained with data from Study 2. In order to provide a heuristic model for research on prosocial behavior between workgroups, findings are integrated into a Context-Specific Contact Model. The model proposes specific effects of contact in different contexts on prosocial behavior at different levels of categorization. Possible mediator and moderator processes are suggested. A number of implications for theory, future research and the management of relations between workgroups are discussed.
