Studies of locomotion in virtual environments assume that correct geometric principles define the relationship between walking speed and environmental flow. However, we have observed that geometrically correct optic flow appears to be too slow during simulated locomotion on a treadmill. Experiment 1 documents the effect in a head-mounted display. Experiment 2 shows that the effect is eliminated when the gaze is directed downward or to the side, or when the walking speed is slow. Experiment 3 shows that the effect is unchanged by stride length. Experiment 4 verifies that the effect is not attributable to image jitter. The change in …

Assessment procedures in social work emerged within the historical context of modernist empiricism. They are lodged in assumptions of objectivity, measurement accuracy, value neutrality and scientific expertise. Within the context of postmodern constructionism, the grounds for traditional assessment are thrown into question. While such critique may seem to threaten the assessment tradition, such a conclusion is unwarranted. Rather, one may locate within the assessment tradition and constructionist writings converging lines of thought. Through the collaborative extension of two assessment exemplars—the genogram and the ecomap—we suggest new and more promising potentials for assessment practices in social work.

During self-motion, the world normally appears stationary. In part, this may be due to reductions in visual motion signals during self-motion. In 8 experiments, the authors used magnitude estimation to characterize changes in visual speed perception as a result of biomechanical self-motion alone (treadmill walking), physical translation alone (passive transport), and both biomechanical self-motion and physical translation together (walking). Their results show that each factor alone produces subtractive reductions in visual speed but that subtraction is greatest with both factors together, approximating the sum of the 2 separately. The similarity of results for biomechanical and passive self-motion support H. B. …
Psychologie Jenseits Postmoderner Kritik, Kenneth J. Gergen
Psychologie Jenseits Postmoderner Kritik, Kenneth J. Gergen
Psychology Faculty Works
Postmodernes Denken formuliert wichtige Einwände gegenüber Vorstellungen von individuellem Wissen, Objektivität und Wahrheit. Statt ihrer wird die gemeinschaftliche (communal) Konstruktion von Wissen betont, liegt der Schwerpunkt auf Objektivität als einer intersubjektiven (relational) Errungenschaft und auf Sprache als einem pragmatischen Medium, das lokale Wahrheiten hervorbringt. Diese Entwicklungen bedeuten nicht notwendigerweise das Ende wissenschaftlicher Psychologie. Vielmehr laden sie dazu ein, eine Reihe neuer Fragen in Hinblick auf die Möglichkeiten traditioneller Forschung und ihrer Bedeutung im kulturellen Leben zu stellen. Wichtiger noch: Eine solche Kritik eröffnet neuartige, theoretisch, methodologisch und praktisch bedeutsame Perspektiven. Anzeichen einer solchen Ausrichtung häufen sich, was zeigt, dass grundlegende …
