In this study the mechanisms that control attention in natural scenes was examined. It was explored whether familiarity with the environment makes participants more sensitive to changes or novel events in the scene. Previous investigation of this issue has been based on viewing 2D pictures/images of simple objects or of natural scenes, a situation which does not accurately reflect the challenges of natural vision. In order to examine this issue, as well as the differences between 2D and 3D environments, two experiments were designed in which the general task demands could be manipulated. The results revealed that familiarity with the environment significantly increased the time spent fixating regions in the scene where a change had occurred. The results support the hypothesis that we learn the structure of natural scenes over time, and that attention is attracted by deviations from the stored scene representation. Such a mechanism would allow attention to objects or events that were not explicitly on the current cognitive agenda.

Is attention drawn to changes in familiar scenes? Karacan, Hacer (Uke); Hayhoe, Mary M. (Informa UK Limited, 2008-01-01) In this study, we examined the mechanisms that control attention in natural scenes. We asked whether familiarity with the environment makes subjects more sensitive to changes or novel events in the scene. Previous investigation of this issue has been based on viewing 2-D images of simple objects or of natural scenes, a situation that does not accurately reflect the challenges of natural vision. We found that familiarity with the environment significantly increased the time spent fixating regions in the scen...
THE ROLE OF SENSE OF COHERENCE AND PHYSICAL ACTIVITY IN POSITIVE AND NEGATIVE AFFECT OF TURKISH ADOLESCENTS Oztekin, Ceyda; Tezer, Esin (2009-06-01) This study investigated the role of sense of coherence and total physical activity in positive and negative affect. Participants were 376 (169 female, 206 male, and 1 missing value) student volunteers from different faculties of Middle East Technical University. Three questionnaires: Sense of Coherence Scale (SOC), Physical Activity Assessment Questionnaire (PAAQ), and Positive and Negative Affect Schedule (PANAS) were administered to the students together with the demographic information sheet. Two separat...
The biomechanical relationship between incisor and condylar guidances in deep bite and normal cases Darendeliler, N; Dincer, M; Soylu, Reşit (Wiley, 2004-05-01) The purpose of this study was to investigate the biomechanical relationship between the condylar and anterior guidances in deep bite malocclusion and control groups. The subjects consisted of 18 deep bite patients and 14 normal occlusions. A four-bar mechanism was described on the lateral cephalogram films and a computer program, for which the lengths of the links measured on the films were the inputs, was developed. The computer program was used to calculate the angles of rotation of the mandible and the c...
Somatotype as a predictor of psychological characteristics of female university students Asci, FH; Kin, A; Kosar, SN (2001-01-01) The purpose of this study was to investigate the interrelationship between somatotype and psychological characteristics including physical self-perception, self-concept and anxiety. Ninety-eight volunteer female university students (M-age =21.60 +/- 1.93) who enrolled in elective courses from Physical Education and Sports Department voluntarily participated in this study. Somatotype components - endomorphy, mesomorphy, ectomorphy- were determined by using Heath Carter Method. In addition, "Marsh Physical Se...
The Effect of Cinematherapy on Perfectionism and Related Schemas Aka, Basak Tuerkueler; Gençöz, Faruk (2010-06-01) This study aimed to reveal the effect of cinematherapy on perfectionism and related early maladaptive schemas and investigate the contribution of participants' identification with the film on this process. Accordingly, demographic information form, Multidimensional Perfectionism Scale (Hewitt & Flett, 1991a; 1991b), three Early Maladaptive Schema (Emotional Inhibition, Unrelenting Standards-Hypercriticalness, Approval. Seeking-Recognition Seeking) items from Young Schema Questionnaire (Young & Brown 2001), ...
