Effective actions motivated by zero-order and first-order actions are examined. Particular attention is devoted to a variational procedure that is consistent with the structure equations involving the Lorentz connection. Attention is drawn to subtleties that can arise in varying higher-order actions and an efficient procedure developed to handle these cases using the calculus of forms. The effect of constrained variations on the field equations is discussed.

Behavioral relevance of consciousness for human action: explorations with the simon task paradigm Gök, Selvi Elif; Hohenberger, Annette Edeltraud; Department of Cognitive Sciences (2016) The motivation of this thesis is to investigate whether consciousness has an effect on human behaviors. To this aim an exploratory approach is adopted where an experimental design with two parts is developed. In the first part, participants are first presented objects moving to the left or to the right in accordance with a rule (i.e. familiarization phase), and then transferred to a subsequent two-choice stimulus-response task for stimuli presented at the center of the screen (i.e. Simon phase). Although th...
Antecedents and consequences of achievement goals Kahraman, Nurcan; Sungur, Semra; Department of Educational Sciences (2011) This study aimed to investigate the antecedents and consequences ofachievement goals. While self efficacy, task value, fear of failure, perceived parents’ and teachers’ achievement goals were investigated as antecedents of achievement goals in science, students’ metacognition and coping strategies were examined as consequences of achievement goals in science. In this investigation, a model of the potential associations among these variables was proposed and tested by using path analysis. 977, 7th grade, ele...
Dynamical aspects of decision making under uncertainty Taşkın, Kemal; Gökçay, Didem; Department of Cognitive Sciences (2016) Decision making is defined as the mental process of choosing among a set of alternatives. Although several aspects of decision making have been investigated so far in cognitive science, dynamics of this process as a whole remained to be studied in detail. In this context, we investigated the effects of consecutive decisions on the current decision in a decision making task under uncertainty. In the attempt of elaborating these effects, we analyzed responses of participants to risky choices in two experiment...
Computer apology: The effect of the apologetic feedback on users in computerized environment Akgun, Mahir; Çağıltay, Kürşat; Tzeng, Jeng-Yi (2005-07-08) Apologizing or praising has various effects on people's motivation levels. One way to employ emotions in computerized environments is to present humanized messages like apologetic statements. In this study, a game offering apologetic statements for a group of subjects was used to understand the effect of apologetic statements in computerized environment. Findings have shown that the apologetic feedbacks made the subjects feel more respected, more comfortable, and more sensitive to their feelings. These find...
Measuring risk tolerance in finance: Does the decision frame matter? Özdemir, Özlem (2013-06-01) Risk taking behavior has great influence on the decision making process of individuals. In this respect, the methodology used in assessing individuals’ risk tolerance becomes an important issue. However, there is lack of unique and commonly used risk tolerance measure in literature. There are mainly two different approaches in measuring risk tolerance in literature; lottery versus financial risk assessment technique (FRT). The purpose of this study is to investigate whether measurement techniques differ wi...
