To judge a book by its weight you need to know its content: Knowledge moderates the use of embodied cues

Participants evaluated a book as more important when it weighed heavily in their hands (due to a concealed weight), but only when they had substantive knowledge about the book. Those who had read a synopsis (Study 1), had read the book (Study 2) and knew details about its plot (Study 3) were influenced by its weight, whereas those unfamiliar with the book were not. This contradicts the widely shared assumption that metaphorically related perceptual inputs serve as heuristic cues that people primarily use in the absence of more diagnostic information. Instead, perceptual inputs may increase the accessibility of metaphorically congruent knowledge or may suggest an initial hypothesis that is only endorsed when supporting information is accessible.     

The effects of affective states on the formation of performance expectancies

Positive vs. negative affective states are associated with the use of broad vs. specific knowledge structures. These findings were applied to the field of performance expectancies. It was predicted that individuals with positive mood should infer their performance expectancies concerning a specific task from their general self-concept, whereas given negative mood, performance expectancies should be inferred from the relevant specific self-concept. In an experiment, positive vs. negative mood was induced in 158 university students. General and specific self-concepts were assessed. Furthermore, we assessed task-specific performance expectancies and task performance. Specific self-concept was predictive of expectancies given negative mood, whereas with positive mood, expectancies could only be predicted on the basis of the general self-concept. Furthermore, mean expectancies were higher and less accurate with positive mood. The results are in line with the theoretical predictions. They underline that affective states also influence the formation of motivational variables like performance expectancies.     

Possibilities of objective assessment of the course of activation in ideomotor training

An active exploration of movement tasks is accompanied with central nervous activation. Its systematical examination needs a teamwork of scientists of various branches of knowledge (i.e. physiology, psychology, sport sciences). Mental training (motor imagination - MI) was chosen as a model for such examinations. In connection with the execution of MI there are characteristic chances of the mean alpha frequency of the EEG, heart rate, respiration rate and skin conductance. The time course of these parameters depends on the number, the duration and the sequence of MI. A graduated submaximal load on ergometer has no influence on the course of the examined parameters. Our investigation allows the conclusion that different activation processes go on within different subsystems during the execution of MI. From a physiological point of view it seems to be necessary that a concrete paradigm of MI must be examined concerning the course of the parameters and, thus, to guarantee the effort of MI.     

Cognitive processes mediating behavioral change.

The present experiment was designed to test the theory that psychological procedures achieve changes in behavior by altering the level and strength of self-efficacy. In this formulation, perceived self-efficacy. In this formulation, perceived self-efficacy influences level of performance by enhancing intensity and persistence of effort. Adult phobics were administered treatments based upon either performance mastery experiences, vicarious experiences., or they received no treatment. Their efficacy expectations and approach behavior toward threats differing on a similarity dimension were measured before and after treatment. In accord with our prediction, the mastery-based treatment produced higher, stronger, and more generalized expectations of personal efficacy than did the treatment relying solely upon vicarious experiences. Results of a microanalysis further confirm the hypothesized relationship between self-efficacy and behavioral change. Self-efficacy was a uniformly accurate predictor of performance on tasks of varying difficulty with different threats regardless of whether the changes in self-efficacy were produced through enactive mastery or by vicarious experience alone.     

Causal Models of Physical Exercise Participation: Testing the Predictive Power of the Construct "Pressure to Change"

This study examines 2 different causal models to predict physical exercise motivation and behavior under a longitudinal perspective. The first model includes 5 latent variables that were hypothesized to have an impact on exercise intention and behavior: behavior-specific social support, exercise self-efficacy, perceived health benefits, perceived barriers, and subjective vulnerability to cardiovascular disease. The second model was based on all variables of the first model, but additionally included the new variable "pressure to change." Pressure to change was defined as the extent to which a person feels the necessity that specific personal life circumstances (e.g., health status, social relations) may not remain as they are and ought to be changed. It was hypothesized that the inclusion of health-related pressure to change would result in a better prediction of exercise intention. The proposed causal models were tested separately at the stages of exercise adoption and maintenance. Covariance structure analyses (LISREL) confirmed that pressure to change may be an important factor in the motivational process that leads to the adoption of regular physical exercise. Adding this latent variable to the basic model improved the amount of explained variance in exercise intention by 6%. Furthermore, the results did not support the assumption that cognitive control is critical especially during the acquisition of exercise behaviors, but may be less influential once the behavioral routines have been established. Our data rather indicate that regular physical exercise, even if performed on a regular basis for years, always remains a behavior that requires a high level of cognitive guidance.     

Gender differences in causal attributions by college students of performance on course examinations

Gender differences in causal attributions and emotions for imagined success and failure on examinations were investigated. Males made stronger ability attributions for success than females, whereas females emphasized the importance of studying and paying attention. Males more than females attributed failure to a lack of studying and low interest, but females were more likely than males to blame an F on a lack of ability. Females experienced stronger emotions than did males; they felt happier than males did after success but felt more like a failure than did males after imagining receiving an F on an examination. Some of the gender differences in causal attributions, especially for ability attributions, depended on the gender-type of the subject matter of the examinations. The implications of these findings are discussed.     

Virtuelle Objekte und ihre Verwendung

Zusammenfassung. Wir leben in einer Epoche, die man als Post-Gutenberg-Epoche bezeichnen kann. Das dominierende Zeichensystem ist nicht mehr die Schrift, sondern das elektronische Zeichen. Ungef?hr das Jahr 1950 wird als Wendepunkt zwischen diesen beiden Epochen angesehen, und zwar deshalb, weil in den Jahren nach dem 2. Weltkrieg die amerikanischen Haushalte mit Fernsehger?ten ges?ttigt waren und sich somit dieses neue Zeichensystem durchgesetzt hatte. Thema dieses Aufsatzes ist die Ver?nderung unserer Zeichensysteme und damit unserer Symbolwelten, der Wandel von der Welt des Schriftzeichens zur Welt des elektronischen Zeichens, die dadurch entstandene M?glichkeit, elektronische Objekte zu schaffen, die ich virtuelle Objekte nennen m?chte, die Manipulation von Objektwahl und Objektbeziehung, die damit einhergeht und die Rolle, die uns Analytikern in einer solchen Welt zukommt. Diese elektronischen Zeichen haben mit gro?em Tempo ein Eigenleben entwickelt, es ist eine ganze Klasse neuer Objekte entstanden, die Klassen der virtuellen Objekte. Dies sind elektronisch ver?nderte, erg?nzte oder rein elektronisch produzierte Objekte. Damit verbunden ist eine Industrialisierung von Objektwahl und Objektbeziehung. Es entsteht die manipulierte Objektwahl und Objektbeziehung und die Verdr?ngung natürlicher Objekte durch virtuelle. Dieser Vorgang ist auch mit einem Wechsel des Sozial- und Kulturverst?ndnisses verbunden. Es entstehen neue Muster des Sozial- und Kulturverst?ndnisses, die man als Industriefeudalismus bezeichnen k?nnte. Ziel des Beitrags ist es, über die Ver?nderung unserer Zeichenwelt und die damit verbundene Industrialisierung von Objektbeziehung zu reflektieren und sie, soweit schon m?glich, zu deuten.

Virtual objects and their application: about the industrial production of object relationships

Summary. We live in an epoch that could be designated as the post-Gutenberg-era. Writing is no longer the dominant sign system. It is replaced by electronic signs. We consider approximately the year 1950 as the turning-point between these two epochs, because by then, in the years after the 2nd World War the American households were saturated with televisions. Thereby, the new sign system asserted itself. The topic of this article is the transformation of our sign system and thereby of our worlds of symbols, the leap from the world of written signs into the world of electronic signs, and the possibility born out of it to create electronic objects, which I prefer to call virtual objects. The manipulation of object-choice and object-relationships accompanying this change and the role assigned to analysts in this new world will be considered as well. These electronic signs developed quickly a life of their own. A totally new class of objects came into being, the class of virtual objects. These are electronically transformed, completed or wholly electronically produced objects. This procedure is accompanied by an industrialization of object-choice and object-relationships. The manipulated object-choice and object-relationship is born and, moreover, a displacement of natural objects through virtual ones. A change of the socio-cultural understanding is also a consequence of this process. New patterns of socio-cultural understanding develop, that could be described as industrial feudalism. The goal of this article is to describe the transformation of our world of signs and the connected industrialization of object relationships, and to interprete them according to our present possibilities.
